;2009-01-05 00:00:00 172;Edison Lecture Series 2009;

Last week, the Department of Electrical & Computer Engineering, IBM, the Central Texas chapter of IEEE, and Whole Foods, sponsored the 5th annual Edison Lecture Series.

Over 2,000 students participated in a free participatory demonstration of the fun and excitment of a career in technology. Companies and governmental organizations showed off robots, computer gaming, renewable energy, solar cars, and more in interactive pre-show demonstrations. The Lecture itself explored the effect of engineering advances on third world economies, communication, and health care.

The Edison Lecture has inspired and informed over 12,000 middle and high school students on The University of Texas at Austin campus over the last 5 years. Next year's topic is Innovation!


;2009-01-12 00:00:00 175;Evans Becomes IEEE Fellow;

Professor Brian L. Evans was elevated to IEEE Fellow, the highest grade of IEEE membership, for contributions to multicarrier communications and image display.

In multicarrier communications, Prof. Evans was recognized for his algorithms to maximize user bit rates in WiMax, cellular and DSL systems. In image display, he was recognized for his algorithms to improve image quality in printers. For both contributions, the algorithms were developed to be amenable for cost-effective implementation in products. Prof. Evans joined the UT Austin faculty in fall 1996.

;2009-01-26 00:00:00 176;Julien, Vikalo, Kwasinski Win CAREER Awards;

The Department of Electrical & Computer Engineering (UT-ECE) is delighted to announce that the National Science Foundation (NSF) has given three of our new professors a Faculty Early Career Development (CAREER) grant.

This highly competitive award is given to young faculty perceived as future leaders in integrating education and research.

Assistant Professor Christine Julien's grant is Opportunistic Middleware for Resource Constrained Delay Tolerant Networks. Haris Vikalo received a grant for Modeling, Estimation and Coding for Biosensor Arrays. Alexis Kwasinski's research project is Highly-available Power Supply through Distributed Generation Technologies: Reliability Analysis Framework Based on Operation Under Critical Conditions.

;2009-02-02 00:00:00 177;Lizy John Elevated to IEEE Fellow;

The department's first female IEEE Fellow, Professor Lizy John, was elevated for contributions to power modeling and performance evaluation of microprocessors. Dr. John has concentrated on allowing microprocessor designers to find problems early in the design process. Since pre-silicon microprocessors cannot be tested with full applications, Dr. John’s team developed a cloning technique to create miniature versions enabling an accurate estimation of performance and power. Dr. John's team has also worked on creating power and thermal stress programs (aka power viruses) to drive designs to extreme conditions and help design robust microprocessors and computer systems.

Another application of the cloning technique from John's group has been to hide the functionality of proprietary applications. Lockheed Martin is supporting John's research to create clones for their proprietary codes, enabling them to share codes without divulging proprietary information.

;2009-02-06 00:00:00 178;Touba Named IEEE Fellow;

Professor Nur Touba was named an IEEE Fellow—the highest grade of IEEE membership—for contributions to test data compression and built-in self-test for integrated circuits. Dr. Touba has developed a number of innovative techniques for automated design of testable and fault-tolerant circuits.

In particular, his research has focused on developing new techniques for built-in self-test (BIST), test data compression, delay fault testing, concurrent error detection, and design-for-testibility (DFT) in core-based designs. His research helps reduce the cost and increase the quality of manufacturing tests.

Dr. Touba served as Program Chair for the 2008 International Test Conference, General Chair for the 2007 Symposium on Defect and Fault Tolerance, and Program Chair for 2008 International Test Synthesis Workshop.

;2009-02-12 00:00:00 179;Neikirk - Wireless Sensors to Monitor Bridge Safety;

ECE professor Dean Neikirk just received funding for a 5-year program to use wireless sensors to identify failing bridges, lower the cost of monitoring those bridges, and improve the safety of new bridges. The $6.8M project addresses a chronic problem for the aging American highway infrastructure.

According to the American Society of Civil Engineers, deferred maintenance has left one-quarter of the nation’s bridges deficient. Congress mandated 2-year inspections in 1971, but at least 17,000 bridges did not meet the requirement in 2008, including 3 out of every 100 freeway bridges. The wireless sensor system being developed by Dr. Neikirk and principal investigator UT Civil Engineering Chairman Sharon Wood will make real-time monitoring possible for fracture-critical bridges (i.e., bridges in which one failing component could bring the entire bridge down), and lower the cost and time required for all bridge inspections.


;2009-02-20 00:00:00 180;Integrating Wind Power into the Grid;

ECE professors, Mack Grady and Surya Santoso, are collecting the data needed to truly integrate wind power into the existing power grid—and creating the first university-lead phasor measurement network in the country. A collaboration between UT, the State of Texas, Austin Energy, and Schweitzer Engineering Inc. will make it possible for power operators in the future to maximize the use of this inexpensive, renewable, and non-polluting energy source.

Only 1% of the world’s electricity is supplied by wind. The reason is fundamental. Power systems are most efficient when production exactly matches demand and wind power is wildly variable and intermittent. Until recently, power engineers could broadly predict wind patterns, but their measurements lacked a common frame of reference. The ability to measure the relative voltage phase angle between two buses without expensive infrastructure allows Grady and Santoso to collect real data in real time and use real results, not projections, to create accurate simulations.

;2009-03-02 00:00:00 181;Smart Surveillance - Aggarwal;

Professor Jake Aggarwal has devoted the last 30 years of his career to making the world a safer place. His research is in computer vision, specifically in smart surveillance systems that identify suspicious activity and alert humans to follow-up. His approach has evolved from the basic problems of determining movement of a 3-dimensional object from 2-dimensional images to a sophisticated system that can recognize aggressive activity even with multiple players and a cluttered background.

Human sight is highly selective. We focus on what is important and filter the rest. It is unbelievably difficult to replicate the judgment that happens automatically and effortlessly for humans with cameras and computers, says Aggarwal. My group is currently studying ways to identify potential threats from suspicious driving patterns, human-vehicle interactions, and human activities. Preliminary results are very promising.

Aggarwal's work was recently cited in The Columbus Dispatch and in The Economist. He is also a recipient of the 2004 IAPR King-Sun Fu Prize, 2005 IEEE Kirchmayer Award, and the 2007 Okawa Prize.


;2009-03-20 00:00:00 183;Saving Energy using Flywheels;

ECE researcher Dr. Mark Flynn is greening ports world-wide by adding flywheels to cargo handling machinery. Flynn's high-speed motor controller design has been incorporated into flywheel energy storage systems sold by Vycon, Inc.

There are approximately 8,000 Rubber Tired Gantry (RTG) cranes operating at sea ports around the world which contribute significantly to port emissions, as such they have become a testing ground for new hybrid technologies. Flywheels provide significant fuel and emissions reductions via the capturing of braking energy generated when a container is lowered. The captured energy is then available to help hoist the next one.

Compared to other energy storage technologies used on RTG cranes such as conventional batteries and ultracapacitors, flywheels do not require routine replacement and offer lower maintenance, higher tolerance for rapid cycling, and freedom from aging and environmental limitations.


;2009-03-23 00:00:00 184;Seth Bank Conducts Nanocomposite Research;

Dr. Seth Bank's research into III-V compound semiconductors could cool down your laptop, increase the capacity and speed of fiber-optics, and make solar cells more efficient. Bank hopes to improve III-V compound semiconductors—used for everything from cell phone transistors to LED's in traffic lights—by embedding semi-metal nanoparticles in them.

One application for his nanocomposites is better connection between layers in multijunction solar cells. Bank is working with a start-up on this and hopes to demo state-of-the-art solar cells later this year. He is also working with ARO and DARPA on developing lasers that can detect trace gases and transmit over fiber-optics. Bank is also trying to grow a new material called graphene (a single layer of carbon atoms) that could replace current computer chip technology, conserving power and producing less heat.

Bank was helped recently when the National Institute of Standards and Technology gave his lab a molecular beam epitaxy (MBE) system. Such systems typically cost a million dollars. MBE has evolved into a popular technique for growing III-V compound semiconductors because it produces high-quality layers with good control of thickness, doping, and composition.

;2009-03-31 00:00:00 185;Improving Communications in Remote Areas;

Professor Christine Julien is using a grant from the National Science Foundation to solve persistent problems posed by delay-tolerant networks (DTNs)—heteterogeneous networks with spotty connectivity. DTNs are the norm in remote areas with inadequate energy resources and mobile nodes, complicating search and rescue operations and third world communications.

Previous solutions have been tailored for specific applications. Julien is stepping back and looking for common characteristics. The optimal solution to the frequent and long-lasting disconnects on DTNs would be communication protocols that adapt to changing conditions on-the-fly. The ability to collect and interpret information about the application's environment would be key to success.

Julien's solution is an adaptive middleware that coordinates communication among mobile applications running on devices that are only intermittently connected. The middleware helps software react to frequent configuration changes that occur as devices move and communication capabilities change.

;2009-04-07 00:00:00 187;Dr. Patt Starts a Dialog;

Professor Yale Patt's keynote address at the 2009 PPoPP conference unleashed a hailstorm of protest from industry programmers that may lead to real change in commercial programming and computer architecture education. According to Ed Burnette on ZDNet, Dr. Patt had three main points: multi-core is not the holy grail, most programmers are stupid, and there should be lots of low-level interfaces for the non-stupid ones to use. The immediate reaction were multiple posts on ZDNet defending the use of high level languages as a matter of expediency, but the conversation quickly began to cover topics like:

Dr. Patt is the co-creator of the HPS paradigm and the two-level branch predictor, both used by almost every microprocessor manufacturer in the computer industry.

;2009-04-16 00:00:00 189;Mark Papermaster Named ECE Fellow;

Long-time External Advisory Committee member and UT-ECE alumnus, Mark Papermaster, was named an ECE Fellow last week. Mark has been instrumental in raising our profile and forging relationships with industry, says Chairman Tony Ambler. We have been very lucky to have his help and guidance on EAC.

Papermaster has over 25 years of experience of product and technology experience. He has an international reputation in the chip design field. Papermaster worked at IBM from 1982-2008. His last position was VP of IBM's blade server division. He begins a new job at Apple as senior vice president of Devices Hardware Engineering, reporting to Apple CEO Steve Jobs, on Friday, April 24. Papermaster will lead Apple’s iPod and iPhone hardware engineering teams.

;2009-04-20 00:00:00 190;Andrea Alù and Nader Engheta Propose New Cloaking Method;

from ScienceNews:

Cell phone antennas, radio receivers and GPS devices may one day go incognito. In a paper to appear in Physical Review Letters, Andrea Alù and Nader Engheta propose a new cloaking method that cancels out the electromagnetic waves bouncing off an object. The concept may ultimately lead to surreptitious sensors that can collect and send messages without detection.

The new cloak manipulates electromagnetic waves — including light — not by blocking out the waves, but by working with them. Previous cloaks worked by diverting waves around an object. We have shown how plasmonic materials and metamaterials may overcome a general and fundamental limit of currently available sensors, in that they are necessarily required to scatter around, affecting their own measurement, says Alù. In our paper, we have set the ground for a new general class of sensing devices that may see without being seen. This may have fundamental implications in conceiving novel non-invasive probing devices for a wide range of biological, optics, physics, and engineering applications.


;2009-04-29 00:00:00 192;IEEE 125th Anniversary Celebration;

UT-ECE, IEEE Central Texas Section, door64, the Austin Chamber of Commerce, and 1,000 engineers celebrated the 125th anniversary of the IEEE at Austin's Goodwill Center.

It was a full day, beginning with a Tech Fair at 11 a.m. Thirty seven local tech companies exhibited between sessions about entrepreneurship, consulting, and career development. ECE Chairman, Tony Ambler, and adjunct professor/Cirrus Logic Fellow, Eric Swanson, participated in a Panel Discussion about The Engineer of 2020.

The 3rd Annual BrainParty/125th Anniversary celebration featured UT-ECE graduate research and IEEE student groups. Free food, drinks, and live music preceeded a presentation of a proclamation by Governor Rick Perry. Only 8 celebrations are being held world-wide, with only 3 in the United States.


;2009-05-01 00:00:00 194;Large-Area Graphene on Copper Possible;

UT-ECE research to be published in the journal Science demonstrates, for the first time, that centimeter-square areas of copper foils can be covered almost entirely with mono-layer graphene bringing this intriguing material one step closer to commercial viability. Graphene, formed with carbon atoms linked together like nanoscopic chicken wire, holds great potential for nanoelectronics. It also shows promise for electrical energy storage, for use in composites, for thermal management, in chemical-biological sensing, and as a new sensing material for ultra-sensitive pressure sensors.

ECE Professors Sanjay Banerjee and Emanuel Tutuc and graduate students Seyoung Kim and Junghyo Nah are co-authors of “Large-Area Synthesis of High-Quality and Uniform Graphene Films on Copper Foils.”


;2009-05-11 00:00:00 195;Suzanne Barber Organizes Identity Management Summit;

Dr. Suzanne Barber is a national leader in identity management and the primary organizer of the recent summit: “The Digital Identity: A Double-Edged Sword”. At the summit, experts from industry, government, and academia discussed how shortfalls in even the most fundamental identity management needs, such as basic standards and definitions, are undermining efforts to make our digital identities as secure as our physical ones.

“In the meantime,” says Dr. Barber “we are developing software agents that can assess the trustworthiness of information from different sources. These ‘intelligent agents’ operate in complex environments with massive amounts of conflicting information. They evaluate the reliability of the source, coordinate information exchange, and can take into account cost considerations and timeliness as well. We are very excited by the rapid progress we are making in this area.”
