The G1- The mythical Google Phone

The G1- The mythical Google Phone

For well over a year, the rumors of a Google phone have been running rampant. After the iPhone made its debut a year and a half ago, hopeful Google-lovers have been fantasizing that the Google phone would address all the shortcomings of the beautiful, but in some ways, limited, Apple smartphone.

I"ve been using the iPhone since it arrived in June 2007. Then I happily upgraded to the 3G model this past July. I love it and couldn"t live without it, but I too was eagerly anticipating the arrival of the first Google phone. After side by side usage for a while, I"ve decided that the iPhone and the Google G1 are very different, and made for very different users. The iPhone is beautiful, simple, and a great media player, but the Google phone is a super-fast, highly customizable extra-smart smartphone.

Twitter Relaunches People Search

Twitter Relaunches People Search

You can now search for people on Twitter - again.

"The microblogging tool's re-launched people search. lets you query the service by username or first/last name to find other users," as per Mashable's Adam Ostrow. Twitter had this feature in the past; but earlier this year it was taken down for technical reason.

From Twitter Blog:Twitter is much more valuable when you can find the accounts of the people or organizations you care about-whether they're friends, news organizations, or the airline that will be taking to see your family over the holidays. You'll notice that our new name search is much faster, more relevant, and it even has a phonetic similarity algorithm which is basically fancy talk for spell check on names.

Computer engineers at Washington University in St. Louis are bringing the minimalist approach to medical care and computing by coupling USB-based ultrasound probe technology with a smartphone, enabling a compact, mobile computational platform and a medical imaging device that fits in the palm of a hand.

William D. Richard, Ph.D., WUSTL associate professor of computer science and engineering, and David Zar, research associate in computer science and engineering, have made commercial USB ultrasound probes compatible with Microsoft Windows mobile-based smartphones, thanks to a $100,000 grant Microsoft awarded the two in 2008. In order to make commercial USB ultrasound probes work with smartphones, the scientists had to optimize every aspect of probe design and operation, from power consumption and data transfer rate to image formation algorithms. As a result, it is now possible to build smartphone-compatible USB ultrasound probes for imaging the kidney, liver, bladder and eyes, endocavity probes for prostate and uterine screenings and biopsies, and vascular probes for imaging veins and arteries for starting IVs and central lines. Both medicine and global computer use will never be the same.

Viral epidemics poised to go mobile

Viral epidemics poised to go mobile
This image shows the different mechanisms of virus transmission between mobile phones.

If you own a computer, chances are you have experienced the aftermath of a nasty virus at some point. In contrast, there have been no major outbreaks of mobile phone viral infection, despite the fact that over 80 percent of Americans now use these devices. A team headed by Albert-Laszlo Barabasi, director of the Center for Complex Network Research at Northeastern University, set out to explain why this is true.

The scientists used calling and mobility data from over six million anonymous mobile phone users to create a comprehensive picture of the threat mobile phone viruses pose to users. The results of this study, reported in the May 22 issue of Science, indicate that a highly fragmented market share has effectively hindered outbreaks thus far. Further, their work predicts that viruses will pose a serious threat once a single mobile operating system's market share grows sufficiently large. This event may not be far off, given the 150 percent annual growth rate of smart phones.

"We haven't had a problem so far because only phones with operating systems, so-called 'smart phones', are susceptible to viral infection," explained Marta Gonzalez, one of the authors of the publication. "Once a single operating system becomes common, we could potentially see outbreaks of epidemic proportion because a mobile phone virus can spread by two mechanisms: a Bluetooth virus can infect all Bluetooth-activated phones in a 10-30 meter radius, while Multimedia Messaging System (MMS) virus, like a number of computer viruses, spreads using the address book of the device. Not surprisingly, hybrid viruses, which can infect via both routes, pose the most significant danger".

This study builds upon earlier research by the same group, which used mobile phone data to create a predictive model of human mobility patterns. The current work used this model to simulate Bluetooth virus infection scenarios, finding that Bluetooth viruses will eventually infect all susceptible handsets, but the rate is slow, being limited by human behavioral patterns. This characteristic suggests there should be sufficient time to deploy countermeasures such as antiviral software to prevent major Bluetooth outbreaks. In contrast, spread of MMS viruses is not restricted by human behavioral patterns, however spread of these types of viruses are constrained because the number of susceptible devices is currently much smaller.

As our world becomes increasingly connected we face unprecedented challenges. Studies such as this one, categorized as computational social science, are necessary to understand group behavior and organization, assess potential threats, and develop solutions to the issues faced by our ever-changing society.

"This is what statistical analysis of complex systems is all about: finding patterns in nature," said Gonzalez. "This research is vital because it puts a huge amount of data into the service of science".

Cell phone ringtones can pose major distraction

Cell phone ringtones can pose major distraction
Students exposed to a briefly ringing cell phone scored 25 percent worse on a test of material presented before the distraction.

A flurry of recent research has documented that talking on a cell phone poses a dangerous distraction for drivers and others whose attention should be focused elsewhere. Now, a newly released study in the Journal of Environmental Psychology finds that just the ring of a cell phone appears to be equally distracting, particularly when it comes in a classroom setting or includes a familiar song as a ringtone.

"In any setting where people are trying to acquire knowledge and trying to retain that information in some way, a distraction that may just seem like a common annoyance to people may have a really disruptive effect on their later retention of that information," said the study's main author, Jill Shelton, a postdoctoral psychology fellow in Arts & Sciences at Washington University in St. Louis.

The study includes an experiment in which Shelton poses as a student seated in the middle of a crowded undergraduate psychology lecture and allows a cell phone in her handbag to continue ringing loudly for about 30 seconds.

iPhone SMS Due September 25

iPhone SMS Due September 25

© bogenfreund
If you remember way back to the iPhone 3Gs launch and the release of iPhone firmware 3.0, you will remember the announcement of tethering and SMS messaging. There were some carriers that had the technology already, some that had it coming soon, and then there was AT&T. They had announced SMS messaging would happen by the end of the Summer, and tethering would happen soon. Well AT&T, guess what. you lied.

In an official announcement this week, AT&T has announced SMS texting plans would be available on September 25th. That is decidedly three-days after summer. Here is the kicker, they have announced that tethering would appear "eventually." So, if SMS text messaging was supposed to be by the end of Summer, and it is late, then Tethering should be released when? What is later than "eventually"? I am not a temporal expert, but three days after eventually might just be never.

I love my iPhone, but I really hate AT&T and their support for the device. Ultimately, they are just shooting themselves in the foot. As soon as the millions of iPhone users can switch carriers, they will. At&T will have no one to blame but themselves. They could have kept me forever if they had just did what they said they would do.

The evolution of mobile phone

The evolution of mobile phone

If you agree with the line of thinking that a picture can replace a thousand words, you would surely agree with the extension - that a model can replace a zillion pictures. So assuming that it would be boring to look at a chart, however well-done, to visualize the evolution of a device, give your eyes a treat by looking at this creation by UK-based designer Kyle Bean to demonstrate the evolution of the mobile phone.

The design captures the evolution of the mobile phone in Russian Babushka doll style - starting from the earliest Motorola DynaTAC 8000X to the current Apple iPhone. A lesson or two for schools to make history more

Smartphone app monitors power consumption

Smartphone app monitors power consumption

A new application for the Android smartphone shows users and software developers how much power their applications are consuming. PowerTutor was developed by doctoral students and professors at the University of Michigan.

Battery-powered cell phones serve as hand-held computers and more these days. We run power-hungry applications while we depend on the phones to be available in emergencies.

"Today, we expect our phones to realize more and more functions, and we also expect their batteries to last," said Lide Zhang, a doctoral student in the Department of Electrical Engineering and Computer Science and one of the application's developers. "PowerTutor will help make that possible".

PowerTutor will enable software developers to build more efficient products, said Birjodh Tiwana, a doctoral student in the Department of Electrical Engineering and Computer Science and another of the program's developers. Tiwana said PowerTutor will allow users to compare the power consumption of different applications and select the leanest version that performs the desired task. Users can also watch how their actions affect the phone's battery life.

PowerTutor shows in real time how four different phone components use power: the screen, the network interface, the processor, and the global positioning system receiver.

To create the application, the scientists disassembled their phones and installed electrical current meters. Then they determined the relationship between the phone's internal state (how bright the screen is, for example) and the actual power consumption. That allowed them to produce a software model capable of estimating the power use of any program the phone is running with less than 5 percent error.

PowerTutor can also provide a power consumption history. It is available free at the Android Market at http://www.android.com/market/.

PowerTutor was developed under the direction of associate professor Robert Dick and assistant professor Morley Mao, both in the Department of Electrical Engineering and Computer Science, and Lei Yang, a software engineer at Google. The work is supported by Google and the National Science Foundation, and was done in collaboration with the joint University of Michigan and Northwestern University Empathic Systems Project.

Benign envy sells iPhones

Benign envy sells iPhones

People are willing to pay more for products that elicit their envybut that's only when they are motivated by a positive, non-malignant form of envy, as per a newly released study in the Journal of Consumer Research
"Our studies showed that people who had been made envious of someone who owned an iPhone were willing to pay 80 Euros more on average," write authors Niels van de Ven, Marcel Zeelenberg, and Rik Pieters (Tilburg University).

The scientists made some important discoveries about the motivations that result from different kinds of envy. "Note that two types of envy exist: non-malignant and malicious envy," the authors explain. "Non-cancerous envy exists if the advantage of the other person is deserved, and motivates people to attain a coveted good or position for themselves. This more motivating type of envy makes people pay an envy premium for the products that elicited their envy." Conversely, malicious envy occurs if the other person is believed to be undeserving; it evokes a desire to "pull down" the other person.

Cell phones help save the lives

Cell phones help save the lives

Simple mobile technology, like basic cell phones, can be used to save the lives of mothers in childbirth, and improve the care of newborns and children, reaching underserved populations in remote areas.

More advanced mobile technology can do even more, such as checking on patients, keeping records, improving diagnosis and therapy in the field, and letting community health workers consult general practitioners and specialists for guidance.

"With mobile technologies for health, called 'mhealth' or 'mobile health,' we're extending capabilities to where they don't exist today," says David Aylward, who heads mHealth Alliance, a partnership founded by the United Nations Foundation, the Rockefeller Foundation and the Vodafone Foundation.

"At the most basic level, mobile phones can be used to keep track of people, call for emergency assistance, remind them of appointments and share information," says Julian Schweitzer, PhD, former Chair of The Partnership for Maternal, Newborn & Child Care (PMNCH) and the Chair of the Finance Working Group for the UN Secretary-General's Global Strategy for Women's and Children's Health, launched in September. "But then you can layer on things like check lists, protocols, the steps to ensure a safe birth and action instructions in particular circumstances," says Dr. Schweitzer.

Increase in smart-phone litigation

Increase in smart-phone litigation
The flurry of recent smart phone patent suits is being driven by technology companies eager to capitalize on the speed and expertise of the US International Trade Commission, says a University of Illinois patent strategy expert Deepak Somaya.

The flurry of smart-phone patent suits at the U.S. International Trade Commission (ITC) is being driven by technology companies eager to capitalize on the speed and expertise of the specialized venue, says a University of Illinois patent strategy expert.

Business professor Deepak Somaya says that this current wave of patent litigation is a "clash driven by company strategies".

"Smart phones combine lots of amazing innovation from both computing and mobile telephony, and technology companies are seeing their patents as a potential source of leverage, as something that can help them improve their competitive position against other firms seeking to take advantage of this great confluence of technologies," he said. "When these firms go court shopping for filing patent cases, a number of of them are choosing to target the ITC over the more typical forum of the federal district courts".

In research that will appear in the management journal Organization Science, Somaya and co-author Christine McDaniel, an economist with the ITC, investigated when companies targeted the ITC over the district courts for their import-related patent disputes. They observed that company strategy, the nationality of the defendant and previous experience with the ITC were significant factors when firms went court shopping for filing patent cases.

"Almost all the research on court-shopping is focused on the policy of the court is this likely to be a favorable or unfavorable court?" Somaya said.

However, the main difference between the ITC an independent, quasi-judicial federal agency that hears trade-related patent cases under section 337 of the Smoot-Hawley Tariff Act and district courts is the degree of specialization found at the ITC.

"At the ITC, 85 percent of cases involve patent issues, whereas the typical district court judge gets one patent case every five years," Somaya said. "Most of the time the district courts are dealing with criminal cases and civil suits. So a district court is a very general purpose forum, whereas the ITC is a highly specialized one. And this specialization goes hand-in-glove with the venue's speed and expertise, which can be very important for some patent cases, depending on the company's strategy".

Taking a patent dispute to the ITC requires that the patent infringement be import-related. Once its criteria are met, however, the ITC "becomes very attractive for a particular type of patent dispute one in which the company's strategy requires a quick and reliable decision," Somaya said.

And, as per Somaya, it is the company strategy aspect that has been attracting more smart-phone patent litigation to the ITC.

"Patent cases are commonly very complicated, and can take up a lot of time and money to resolve," he said. "But since the ITC has a streamlined and fast procedure, you don't have the same burden of educating a judge or jury about what the technology is, what the relevant case law is, and so on. There is a lot of expertise in the forum already, so the adjudication is fast, less random and, relatively-speaking, cost effective".

The one disadvantage to specialized venues such as the ITC is that they're less conducive to settling outside of court.

"Specialized venues don't leave much room for either party to play out the negotiation game," Somaya said. "If you're thinking about settling, which can be very cost effective in patent disputes, you often need more time time to conduct negotiations, time for both sides to adjust their expectations, time to devise a mutually acceptable agreement. Going to the ITC might instead rush you through adjudication and force you to incur all the accompanying costs.

"In that case, you appears to be better off going to a district court simply to have the time and flexibility to negotiate a settlement".

Time, however, is the one resource that companies like Nokia, Apple and Motorola all currently embroiled in patent litigation at the ITC don't have.

"When the dispute involves a pivotal fast-moving technology, time is of the essence," Somaya said. "Additionally, these smart-phone patents have very high strategic stakes for firms, so you have a situation that might be very difficult for the two parties to settle on".

Once a firm has reached this point-of-no-return with litigation, it makes sense to go with the cheaper, faster, and more expert venue, which is commonly the ITC, Somaya says.

"Essentially, there's so much at stake for the company owning the patents that they don't see an easy way to settle the dispute, so what they really need is a court decision in their favor," he said. "A company such as Apple simply wants to shore up the competitive advantage of the iPhone, and may not see much point in trying to negotiate a settlement".

How to Make Your Computer Live Longer

How to Make Your Computer Live Longer
© psd


Sometime I think losing a laptop is almost as traumatic as losing a pet. You spend so much time and effort getting to know what it, trying new things. You waste hours of your life playing with it. It even follows you around.

Okay, so I might be pushing the analogy, but the truth is, most of us don"t have the money to get a new laptop every 6 months. We"d like to keep the one we have alive and running for as long as possible.

So here are a few useful little tips that might extend the life your computer. Don"t worry, you probably already know them, but reminders never hurt anyone:

1. Shut it Down: This may sound simple but a number of of us just close the lid, turn of the monitor or set it to sleep mode. Completely shutting your computer down will keep it from overheating and leaking memory. Think of your computer like your brain, it can"t function without a good night"s sleep.

2. Defrag!: Again, another simple "duh" moment. Defrag your computer. Most PCs will even let you set up a regular defrag schedule once a week. Cleaning up your files on a regular basis will also keep your computer functioning at optimal speed.

3. Keep it Clean: During your regularly scheduled defrag, go ahead and run a scan for viruses, spyware, malware, all that bad stuff you can pick on the internet. Find a good program to keep your PC"s health good.

4. Don"t Drop It: Look, be nice to your laptops. Keep them in safe places, don"t expose them to weird temperatures and be sure not to eat or drink near them if possible. Also pets. I lost a laptop a few years ago to a cat pouncing on and then hairballing all over my keys, it broke my screen and something gross seeped into the circuitry. Trust me, helping your computer and your pets avoid each other is a good idea.

These might not be the most enlightening tips, but they"ll go along way in keeping your computer chugging along for an extra year or so.

Do you have tips for adding an extra life to your laptop?

Moving Video to "Captcha" Robot Hackers

Moving Video to

We see the popular "captcha" security mechanism often - wavy letters websites ask us to type into a box. It's used by web pages and newsletter sign-up forms to prevent computer robots from hacking into servers and databases. But these codes, which are becoming increasingly complicated for an average person to use, are not immune to security holes.

A research project led by Prof. Danny Cohen-Or of Tel Aviv University's Blavatnik School of Computer Sciences demonstrates how a new kind of video captcha code appears to be harder to outsmart. The foundation of the work, presented at a recent SIGGRAPH conference, is really pure research, says Prof. Cohen-Or, but it opens the door so security scientists can think a little differently.

"Humans have a very special skill that computer bots have still not been able to master," says Prof. Cohen-Or. "We can see what's called an 'emergence image' - an object on a computer screen that becomes recognizable only when it's moving - and identify this image in a matter of seconds. While a person can't 'see' the image as a stationary object on a mottled background, it becomes part of our gestalt as it moves, allowing us to recognize and process it".


A truly "emerging" technology

In the new research paper, co-authored with colleagues in Taiwan, Saudi Arabia and India, Prof. Cohen-Or describes a synthesis technique that generates pictures of 3-D objects, like a running man or a flying airplane. This technique, he says, will allow security developers to generate an infinite number of moving "emergence" images that will be virtually impossible for any computer algorithm to decode.

"Emergence," as defined by the researchers, is a unique human ability to collect fragments of seemingly useless information, then synthesize and perceive it as an identifiable whole. So far, computers don't have this skill. "Computer vision algorithms are completely incapable of effectively processing emergence images," says Prof. Cohen-Or's faculty colleague Dr. Lior Wolf, a co-author of the study.

The researchers warn that it will take some time before this research can be applied in the real world, but they are currently defining parameters that identify the "perception difficulty level" of various images that might be used in future security technologies.

Finding Waldo in cyberspace
"We're not claiming in our research paper that we've developed a whole new captcha technology," says Prof. Cohen-Or. "But we are taking a step towards that - something that could lead to a much better captcha, to highlight the big difference between men and bots. If it were to be turned into a solution, however, we wouldn't be able to give humans a multiple choice answer or common word answer for what they see, so we'll need to develop a way to use it. We have a few ideas in the works".

The scientists are also developing methods of automatically generating "hidden" images in a natural background, like a pastoral mountain setting - a digital "Where's Waldo?" game. "We're trying to hide images like eagles or a lion in mountainscape," says Prof. Cohen-Or. Because the moving image blends into a static background, it's hard for bots to understand what the human eye perceives with only minimal training.

"This could be a tough thing for a robot to crack, so we're working hard to make it practical," he emphasizes. "A good captcha has to be something that's easy for people but hard for a machine".

Back to the future for computers

Back to the future for computers

A presentation at the Optical Fiber Communication Conference and Exposition/National Fiber Optic Engineers Conference (OFC/NFOEC) in San Diego on March 24 will examine the technologies that will emerge in the next three to four years to power warehouse-scale computing data centers, upon which companies such as Google, Amazon, Microsoft, Yahoo, Facebook, and a number of more are increasingly relying.

The advent of distributed, massive-scale "cloud computing" today is something of a return to the early part of 1980s, when computing was of a different sort. Rather than individual desktop or laptop machines, which are the current norm, computers were commonly time-shared among multiple users working on "dumb" terminals connected to a central machineoften located in some remote corner of the building.

Cloud computing basically makes use of the Internet to connect remote users to massive, warehouse-scale data centers that house large networks of processors and memory for crunching and storing data. These warehouse data centers promise to lower computing costs by sharing resources and taking advantage of economies of scale, says Network Architect Cedric Lam of Google, and they will relieve users of the hassles of maintaining and upgrading equipment and backing up their data.

But the real advantage of this type of computing, adds Lam, is portability. "Users enjoy the convenience of accessing their data from anywhere and at any time, so long as they have a network connection," he says.

At OFC/NFOEC 2010, Lam will discuss the optical interconnects and other optical networking technologies that will emerge in the next few years. Low-cost, high-bandwidth and high-density optical fiber interconnects are essential for this type of computing because they make it possible to lower power consumption and increase connectivity among individual processors within the clusters of connected computers in the warehouses. Optical connectivity is also used for the ultra-long-haul transport of information between data centers.

On the long-haul side, what will be most important in the next few years, Lam says, is maximizing the capacity of existing and newly installed optical lines, and minimizing the need for OEO regenerators over long distances. He says this appears to be accomplished by exploring new optical spectra besides the traditional C-band, and new ways to carry information, e.g. using new modulation formats and signal processing techniques to improve spectral efficiency and tolerances to transmission impairments.

How laptops can enhance learning

How laptops can enhance learning

Despite the distraction potential of laptops in college classrooms, new research shows that they can actually increase students' engagement, attentiveness, participation and learning.

To achieve this, however, the instructor must set the right stage, says University of Michigan professor Perry Samson.

Samson is a professor in the Department of Atmospheric, Oceanic and Space Sciences who has received honors for his educational technology work.

He has developed robust interactive student response system called LectureTools that utilizes students' laptops. A paper about how students report that LectureTools affected their learning is reported in the May edition of the journal Computers & Education.

"If you allow laptops in the classroom without a plan for how you'll use them, you can potentially invite disaster. It's unlikely that students will be so entranced by class material that they won't wander off to their favorite social networking sites," Samson said. "The key is to deliberately engage students through their computers. LectureTools does just that".

LectureTools is an interactive student response system and teaching module. Instructors at more than 400 colleges and universities have set up accounts to use it.

Samson recently surveyed close to 200 students who, over the past three semesters, have taken his Extreme Weather lecture course that utilized LectureTools. Students reported that while they did sometimes stray from in-class tasks, laptops with LectureTools made them feel more attentive, engaged and able to learn, compared with classes that don't use the system.

"Our surveys showed that while laptop computers can be a distraction, students of this generation feel that they are capable of productive multitasking," Samson said.

Through LectureTools, laptops serve as robust "clickers," providing drastically more interaction than the class polling that clicker-based student response systems offer.

LectureTools also allows students to take notes directly on lecture slides. Students can anonymously ask the instructor's aide a question through a chat window during class, and others can see these questions and answers. Students can also rate their own understanding of each slide, giving the professor valuable feedback.

"It is the first successful instance I've seen of dramatic use of information technology to augment the real-time classroom experience," said John King, vice provost for academic affairs and the William Warner Bishop Collegiate Professor of Information. "LectureTools significantly increases the interactivity between the student and the instructor without disrupting the flow of the class. The instructor gets a lot more detailed information about where the students are while maintaining normal operation in the class".

Close to half of students surveyed said that having a laptop in class increased the amount of time they spent on tasks uncorrelation to the lecture. But a full 78 percent agreed that laptops in class made them more engaged. Approximately half said that having their laptops made them more attentive. Seventy percent said laptops had a positive effect on their learning.

LectureTools significantly increased class participation as well. The system allows students to chat with an instructor's aide, posing questions without raising a hand and having to speak up in front of their peers.

"You can ask the dumb question without fear," Samson said.

More than half of the students asked at least one question during the semester, which is a much higher percentage than Samson saw in classes without LectureTools, he said.

The paper is called "Deliberate Engagement of Laptops in Large Lecture Classes to Improve Attentiveness and Engagement".

Barrier to faster integrated circuits

Barrier to faster integrated circuits

College Park, MD (June 29, 2010) -- Integrated circuits, which enable virtually every electronics gadget you use on a daily basis, are constantly being pushed by the semiconductor industry to become smaller, faster, and cheaper. As has happened a number of times in the past and will continue in the future, integrated circuit scaling is perpetually in danger of hitting a wall that must be maneuvered around.

As per Maxime Darnon, a researcher at the French National Center for Scientific Research, in order to continue increasing the speed of integrated circuits, interconnect insulators will require an upgrade to porous, low-dielectric constant materials. Darnon and his colleagues discuss the details in the Journal of Applied Physics, which is published by the American Institute of Physics (AIP).

"The integration of a replacement, porous SiCOH (pSiCOH), however, poses serious problems such as an unacceptable 'roughening' that occurs during plasma processing," explains Darnon. "This is considered a 'showstopper' to faster integrated circuits at the moment, so a fundamental understanding of the roughening mechanisms that occur during the etch process of integrated circuit manufacturing is highly desirable to material designers and etch-process engineers.

Darnon's research team proposes a mechanism for the roughening of pSiCOH materials etched in a fluorocarbon-based plasma. They've shown that the problematic roughness results from a cracking of the denser top surface under ion bombardment, and that this roughness propagates through a slower etching of the dense top surface than the modified porous material beneath it. Perhaps more importantly, the team recommends ways to minimize this phenomenon so that the "showstopper" will only be a speedbump on the road to faster integrated circuits.

Small wires make big connections

Small wires make big connections

University of Illinois engineers have developed a novel direct-writing method for manufacturing metal interconnects that could shrink integrated circuits and expand microelectronics.

Integrated chips are made by wiring multiple transistors and electronic components together to perform complex functions. The connections between chips and circuit boards traditionally are made from pre-fabricated metal wires that connect to a designated bonding pad on a chip.

"Integrated functions require a number of wire connections. It's tedious and time-consuming to make and increases cost," said Min-Feng Yu, a professor of mechanical science and engineering at Illinois.

In addition, the bonding pad for traditional wire bonds takes up a substantial area of space. As technology has moved toward smaller electronics, shrinking wiring has been a substantial obstacle. A number of microelectronic devices are much smaller than the mandatory 50-by-50 micron square bonding site, prohibiting integrated functions on the very small scale.

"There's no existing cost-effective technology that would allow you to wire-bond microstructures," said Yu, "so let's get rid of those wires, and instead, why not directly produce them on-site between the connection points?".

Yu and graduate student Jie Hu developed a direct-write technique that produces tiny pure metal wires much smaller in diameter than traditional wires and requiring two orders of magnitude less bonding area. In a paper appearing in the July 16 edition of Science, they demonstrate as a number of as 20 of their new wires bonded to a single standard bonding site.

"This technique means the pads can be much smaller than what's needed for traditional wire-bonding technology," Yu said. This reduction in area could allow manufacturers to produce more chips per wafer of semiconductor material. It could also enable more complex integrated functions in microelectronics.

The pair have demonstrated their technique with both copper and platinum wires, and plan to explore the technique with other metals.

Yu likens their technique to writing with a fountain pen. "People's mindset is that you draw a line on a surface, but what we're doing is writing to 3-D space," he said.

The duo loaded a micropipette - a device that dispenses tiny amounts of liquid - with a copper electrolyte solution. When the pipette comes into close contact with the surface, a liquid bridge forms between the pipette tip and the bonding pad. The scientists then apply an electric current, which causes the copper in the solution to deposit as solid metal. As the tip moves through space, copper continues to deposit from the solution in the pipette, like ink from a pen, creating a wire. The challenge for Yu and Hu was calculating the correct speed to move the pipette tip to maintain the liquid bridge between the nozzle and the growing wire.

"It's liquid, so it can easily be shaped," Yu said. "As long as you maintain your speed within a certain range, you will always be able to produce uniform, high-quality wires."

They also had to figure out how to "write" the wires laterally for chip-to-chip bonding. Typical micropipette nozzles are flat at the end, but too much tilting breaks the liquid contact. The Illinois duo observed that a notched nozzle, with a 90-degree cut in the side, allowed lateral movement, meaning that the wires can arc from one bonding site to another, even if the chips are stacked or tiered.

The process is automated, so Yu hopes to develop arrays of micropipettes to produce wire bonds in bulk for more efficient manufacturing.

"An advantage is that you can do this in parallel," he said. "Instead of one nozzle, suppose you have 10, 20 or 100 working simultaneously. In one step, you can make tens or hundreds of bonds, and that is cost-saving."

In addition to wire bonds, the technique could produce a myriad of metal microstructures for various applications.

"The ability to fabricate metallic structures in 3-D can open up a number of other opportunities," Yu said. "It has lots of desirable properties aside from the electrical ones. You can imagine the structures that take advantage of the different properties of metal."

Spintronics' for next-generation computers

'Spintronics' for next-generation computers

Using powerful lasers, Hui Zhao, assistant professor of physics and astronomy at the University of Kansas, and graduate student Lalani Werake have discovered a new way to recognize currents of spinning electrons within a semiconductor.

Their findings could lead the way to development of superior computers and electronics. Results from their work in KU's Ultrafast Laser Lab would be reported in the recent issue of Nature Physics, a leading peer-evaluated journal, and was posted online in early August.

Zhao and Werake research spin-based electronics, dubbed "spintronics."

"The goal is to replace everything - from computers to memory devices - to have higher performance and less energy consumption," said Zhao.

The KU investigator said that future advancements to microchips would require a different approach for transmitting the sequences of ones and zeros that make up digital information.

"We have been using the charge of the electron for several decades," said Zhao. "But right now the size of each device is just 30 to 50 nanometers, and you don't have a number of atoms remaining on that tiny scale. We can't continue that way anymore because we're hitting a fundamental limit".

Instead of using the presence or absence of electronic charges, spintronics relies on the direction of an electron's rotation to convey data.

"Roughly speaking, an electron can be viewed as a tiny ball that spins like a baseball," said Zhao. "The difference is that a baseball can spin at any speed, but an electron can only spin at a certain speed - either counterclockwise or clockwise. Therefore, we can use one spin state to represent 'zero' and another to represent 'one.' Because a single electron can carry this information, this takes much less time and much less energy".

However, one major hurdle for spintronics scientists has been the difficulty in detecting the flow of spinning electrons in real time.

"We haven't been able to monitor the velocity of those spinning electrons, but velocity is linked to the spin current," Zhao said. "So there's been no way to directly detect the spin current so far".

The discovery by Zhao and Werake changes that.

The KU scientists have discovered that shining a laser beam on a piece of semiconductor generates different color lights if the spinning electrons are flowing, and the brightness of the new light is correlation to the strength of the spin current.

The optical effect, known as "second-harmonic generation," can monitor spin-current in real time without altering the current itself. Zhao compares his new method with a police officer's radar gun, which tracks a car's speed as it passes.

This vastly improves upon spin-current analysis now in use, which the KU researcher says is akin to analyzing still photographs to determine a car's speed, long after the car has sped away.

"Spintronics is still in the research phase, and we hope that this new technology can be used in labs to look at problems that interest researchers," said Zhao. "As spintronics become industrialized, we expect this could become a routine technique to check the quality of devices, for example".

New Pathsfor a Stressed-Out Internet

New Pathsfor a Stressed-Out Internet

The San Diego Supercomputer Center and Cooperative Association for Internet Data Analysis (CAIDA) at the University of California, San Diego, in a collaboration with scientists from Universitat de Barcelona in Spain and the University of Cyprus, have created the first geometric "atlas" of the Internet as part of a project to prevent our most ubiquitous form of communication from collapsing within the next decade or so.

In a paper published this week in Nature Communications, CAIDA researcher Dmitri Krioukov, along with Marián Boguñá (Universitat de Barcelona) and Fragkiskos Papadopoulos (University of Cyprus), describe how they discovered a latent hyperbolic, or negatively curved, space hidden beneath the Internet's topology, leading them to devise a method to create an Internet map using hyperbolic geometry. In their paper, Sustaining the Internet with Hyperbolic Mapping, the scientists say such a map would lead to a more robust Internet routing architecture because it simplifies path-finding throughout the network.

"We compare routing in the Internet today to using a hypothetical road atlas, which is really just a long encoded list of road intersections and connections that would require drivers to pore through each line to plot a course to their destination without using any geographical, or geometrical, information which helps us navigate through the space in real life," said Krioukov, principal investigator of the project.

Now imagine that a road - or in the case of the Internet, a connection - is closed for some reason and there is no geographical atlas to plot a new course, just a long list of connections that need to be updated. "That is basically how routing in the Internet works today - it is based on a topographical map that does not take into account any geometric coordinates in any space," said Krioukov, who with his colleagues at CAIDA have been managing a project called Archipelago, or Ark, that constantly monitors the topology of the Internet, or the structure of its interconnections.

Like a number of experts, however, Krioukov is concerned that existing Internet routing, which relies on only this topological information, is not really sustainable. "It is very complicated, inefficient, and difficult to scale to the rapidly growing size of the Internet, which is now accessed by more than a billion people each day. In fact, we are already seeing parts of the Internet become intermittently unreachable, sinking into so-called black holes, which is a clear sign of instability".

Krioukov and colleagues have developed an in-depth theory that uses hyperbolic geometry to describe a negatively curved shape of complex networks such as the Internet. This theory appears in paper Hyperbolic Geometry of Complex Networks, published by Physical Review E today. In their Nature Communications paper, the scientists employ this theory, Ark's data, and statistical inference methods to build a geometric map of the Internet. They show that routing using such a map would be superior to the existing routing, which is based on pure topology.

Instead of perpetually accessing and rebuilding a reference list of all available network paths, each router in the Internet would know only its hyperbolic coordinates and the coordinates of its neighbors so it could route in the right direction, only relaying the information to its closest neighbor in that direction, as per the researchers. Known as "greedy routing", this process would dramatically increase the overall efficiency and scalability of the Internet. "We think that using such a routing architecture based on hyperbolic geometry will create the best possible levels of efficiency in terms of speed, accuracy, and resistance to damage," said Krioukov.

However the scientists caution that actually implementing and deploying such a routing structure in the Internet might be as challenging, if not more challenging, than discovering its hidden space. "There are a number of technical and non-technical issues to be resolved before the Internet map that we found would be the map that the Internet uses," said Krioukov.

A computer may drive your car someday

NeuFlow is a supercomputer that mimics human vision to analyze complex environments, such as this street scene. (Image: Eugenio Culurciello/e-Lab)

Navigating our way down the street is something most of us take for granted; we seem to recognize cars, other people, trees and lampposts instantaneously and without much thought. In fact, visually interpreting our environment as quickly as we do is an astonishing feat requiring an enormous number of computations-which is just one reason that coming up with a computer-driven system that can mimic the human brain in visually recognizing objects has proven so difficult.

Now Eugenio Culurciello of Yale's School of Engineering & Applied Science has developed a supercomputer based on the human visual system that operates much more quickly and efficiently than ever before. Dubbed NeuFlow, the system takes its inspiration from the mammalian visual system, mimicking its neural network to quickly interpret the world around it. Culurciello presented the results Sept. 15 at the High Performance Embedded Computing (HPEC) workshop in Boston, Mass.

The system uses complex vision algorithms developed by Yann LeCun at New York University to run large neural networks for synthetic vision applications. One idea-the one Culurciello and LeCun are focusing on, is a system that would allow cars to drive themselves. In order to be able to recognize the various objects encountered on the road-such as other cars, people, stoplights, sidewalks, not to mention the road itself-NeuFlow processes tens of megapixel images in real time.

The system is also extremely efficient, simultaneously running more than 100 billion operations per second using only a few watts (that's less than the power a cell phone uses) to accomplish what it takes bench-top computers with multiple graphic processors more than 300 watts to achieve.

"One of our first prototypes of this system is already capable of outperforming graphic processors on vision tasks," Culurciello said.

Culurciello embedded the supercomputer on a single chip, making the system much smaller, yet more powerful and efficient, than full-scale computers. "The complete system is going to be no bigger than a wallet, so it could easily be embedded in cars and other places," Culurciello said.

Beyond the autonomous car navigation, the system could be used to improve robot navigation into dangerous or difficult-to-reach locations, to provide 360-degree synthetic vision for soldiers in combat situations, or in assisted living situations where it could be used to monitor motion and call for help should an elderly person fall, for example.

Other collaborators include Clement Farabet (Yale University and New York University), Berin Martini, Polina Akselrod, Selcuk Talay (Yale University) and Benoit Corda (New York University).

Netbooks Versus the Competition

Netbooks Versus the Competition

Sometimes, in life, the answers are very apparent, but that is not always the case. The matter of choosing the gear to outfit your office is not always as easily settled as one might think. Is it best to go with a PC or a Mac? Can I really afford the price associated with some of these models? What about the printer? Is the thought of printing the number of pages required in my office really practical given the cost of ink cartridges?

These are the sorts of questions that can arise when trying to make those initial decisions to build an office, or even the decisions regarding replacement of the out of date goods of yesteryear. Another question that many are finding themselves asking today is "Notebook, netbook, or tablet?" Consider this article for information to make that decision easier.

What are my options?
Buying a computer today is nothing like what it was ten years ago. First of all, walking out of the store with a computer might only mean carrying a small, traditional plastic bag. After all, many of the tablets and even some notebooks are so thin and light weight today that they could easily fit in a woman's purse and be carried without the person even feeling the added weight. Added to that, however, is the furthered agony of decision making. No longer is it as simple as choosing between five or ten desktop models in the local electronics store. Instead one is faced with a number of options for portable computing, including netbooks, notebooks, and the tablet. Most are familiar with all that a notebook (aka laptop) can do, so consider these evaluations of how the others stack up.

The newest thing in computer land is the tablet. These low cost, light weight handy devices are perfect for those looking for a secondary computer, or those who wish only to use the computer for photos, music, games, and email. They do have the internet as well, and a number of fun, functional, and funky applications, but they also have a couple major drawbacks. The first is that there is not yet a real functional version of traditional word processing and spreadsheet softwares that work on the tablet. Surely that will change in the near future, but as of now, that it something that one should not expect to accomplish on the tablet. Even Google Docs and Microsoft's online versions of word processing are not where they need to be to make this device functional in that way. The second major flaw is printing. You are not going to easily find ink cartridges that will work with these mini computers. This is going to change in the very near future as wireless printing has started to become a possibility, but you will still be limited when compared to the other computers that offer a wide variety of printer from ink cartridge or toner, wired or wireless, all-in-one or single function.

Netbooks, similarly, are newer to the market and have a number of advantages and disadvantages as compared to the more traditional notebook. These are not going to feature many of the added perks of a traditional computer, such as the DVD/CD drive and extended keyboards. However, the ultra-mini models, are light weight and easily carted from one venue to another, where they can be flipped open to do most everything that a traditional laptop can do, taking up a fraction of the space. The best part is, that unlike the tablet, these USB supporting mini pads are able to work with nearly every printer on the market, which means that you, like the rest of the computer world will also have another decision to make. Which brand? Which model? Ink cartridge or toner? Manufacturer's ink or third party?

Tech Solutions Start With Pattern Recognition

Tech Solutions Start With Pattern Recognition
Buy something online, enter your credit card number and mailing address. Simple. Then you come to the box with the CAPTCHA, the Completely Automated Public Turing Test to Tell Computers and Humans Apart. Here, the website attempts to confirm that you're a human, not some robot about to commit a cybercrime. You dutifully copy down the warped, watery-looking letters.

Incorrect. Another captcha appears. You try again. Also incorrect. A third captcha appears. You start rethinking your purchase.

University at Buffalo computer scientist Venu Govindaraju, who, along with his UB colleagues, pioneered machine recognition of human handwriting, believes that this annoying 21st-century problem has a decidedly old-fashioned solution: handwriting.

"Here at UB's Center for Unified Biometrics, we're the only ones who have proposed and thoroughly studied handwritten captchas," says Govindaraju. "Our perspective is that humans are good at reading handwriting, machines are not. It comes naturally to humans. But computer researchers typically consider handwriting a hopeless case, until someone comes along and shows them that it isn't".

Govindaraju should know. Research he and his UB colleagues conducted in the 1990s helped the U.S. Postal Service establish the first machines that could read handwritten addresses, a feat that a number of at the time -- particularly in industry -- said simply could not be done. In 1996, after years of research, the UB research enabled the USPS to be able to start machine-reading of handwritten addresses, boosting efficiency and saving the agency millions of dollars each year.

Govindaraju believes a similar success can occur with captchas. One of his doctoral students at UB has graduated and was hired by Yahoo! on the basis of his work developing "simulated" handwritten captchas.

"We developed an archive that can automatically generate as a number of different styles of handwriting as we want," says Govindaraju.

The research is based on pattern recognition, a subfield of machine learning in computer science that is concerned with developing systems based on detecting patterns in data.

Similar issues are being studied by Govindaraju and his UB colleagues in order to develop "smart room" technologies, supported by an HP Labs Innovation Research award.

"Smart rooms" are indoor environments equipped with sensitive, but unobtrusive devices, such as cameras and microphones that can identify and track the movements and gestures of inhabitants for a broad range of applications, from providing supplemental supervision in assisted living facilities for the elderly or disabled, to monitoring office workplaces and retail establishments for security. Eventually, the goal is to extend "smart room" features to larger arenas, such as shopping centers, airports and other transportation centers.

Biometrics that CUBS scientists are studying for "smart room" applications include hand gestures as well as the more common biometrics of facial, voice and gait recognition.

"This, too, is all pattern recognition," Govindaraju says, "but instead of letters, here, we're trying to standardize gestures.

"It's like developing an alphabet of gestures so machines can be programmed to do gesture recognition. The idea is to control objects on a monitor without technology," he says.

Since its founding in 2003, CUBS has attracted approximately $10 million in federal and industry funding and has produced 17 doctoral-level graduates. The center advances machine learning and pattern recognition technologies to build engineered systems for both civilian and homeland security applications. It develops new methods for customizing devices that use data from physical biometrics, such as fingerprints, hand geometry and iris scans; behavioral biometrics, such as signature, voiceprint and gait; and chemical biometrics, such as DNA and body odor.

Is Satellite Internet for You?

Is Satellite Internet for You?

With so many broadband choices available today, it can be overwhelming when selecting the best choice for you. Satellite internet is a great broadband choice, but it's not the best option for everyone. How do you know if Satellite's right for you? Here are a few questions that will help you decide:
  1. Do you have access to a telephone line or a cable TV line? For those that aren't plugged into these networks, satellite internet is the way to go. Satellite internet delivers internet access through over-the-air satellite waves, and therefore aren't limited by the physical infrastructure the same way DSL, Cable, and even Fiber Optics broadband services are. That means, for those in remote parts of the world, or those that are in a mobile set-up (e.g. mobile home), satellite internet makes plenty of sense.
  2. Do you have space for a satellite dish? Sounds obvious, but it's necessary to have space to install an outdoor dish with a clear line-of-sight to the southern sky. If unsure, it might be worth it to consult with a provider's technician on whether your set-up is optimal for satellite service before signing any agreement, especially for multi-story apartment or condominium units.
  3. Do you live somewhere with inclement weather? On the flipside, the fact that satellite internet is not tied to a physical infrastructure means its subject to connectivity problems with moisture and precipitation in the atmosphere. Heavy storms may even cause prolonged periods of signal outages. It's, therefore, important to take into consideration the normal weather patterns in and around your area.
  4. Is speed a priority? Satellite internet, while considerably faster than traditional dial-up internet, ranges slower in download/upload speeds relative to other broadband solutions. Consumers can typically get 5mbps at the high-end for satellite service. Compare that to 15+mbps for cable, DSL, and fiber optics services. For casual internet users that require internet to email, browse the web, and chat with friends, satellite internet should be sufficient. But for heavier users, online gamers, those that download lots of media or stream video frequently, and business professionals that require VPN or VoIP connections, it might make sense to look elsewhere. Particularly for hard-core gamers, transmission latency in satellite internet might make for a frustrating experience.
  5. How much are you willing to spend? With satellite internet access, you get mobility and freedom from physical infrastructures. However, on average, the monthly rate of satellite service per mbps is the most expensive out of all the broadband solutions.

Better control of building blocks for quantum computer

Better control of building blocks for quantum computer
(Beeld: Artist's impression of the spin-orbit qubit. Like in a yo-yo toy, by moving the electron one controls its spin. Credit: Gemma Plum)

Researchers from the Kavli Institute of Nanoscience at Delft University of Technology and Eindhoven University of Technology have succeeded in controlling the building blocks of a future super-fast quantum computer. They are now able to manipulate these building blocks (qubits) with electrical rather than magnetic fields, as has been the common practice up till now. They have also been able to embed these qubits into semiconductor nanowires. The scientists' findings have been reported in the current issue of the science journal Nature (23 December).

Spin
A qubit is the building block of a possible, future quantum computer, which would far outstrip current computers in terms of speed. One way to make a qubit is to trap a single electron in semiconductor material. A qubit can, just like a normal computer bit, adopt the states '0' and '1'. This is achieved by using the spin of an electron, which is generated by spinning the electron on its axis. The electron can spin in two directions (representing the '0' state and the '1' state).

Electrical instead of magnetic.

Until now, the spin of an electron has been controlled by magnetic fields. However, these field are extremely difficult to generate on a chip. The electron spin in the qubits that are currently being generated by the Dutch researchers can be controlled by a charge or an electric field, rather than by magnetic fields. This form of control has major advantages, as Leo Kouwenhoven, scientist at the Kavli Institute of Nanoscience at TU Delft, points out: "These spin-orbit qubits combine the best of both worlds. They employ the advantages of both electronic control and information storage in the electron spin".

Nanowires.

There is another important new development in the Dutch research: the researchers have been able to embed the qubits (two) into nanowires made of a semiconductor material (indium arsenide). These wires are of the order of nanometres in diameter and micrometres in length. Kouwenhoven: "These nanowires are being increasingly used as convenient building blocks in nanoelectronics. Nanowires are an excellent platform for quantum information processing, among other applications".
