CSE Department Seminar by Dr. Krishna Kavi on November 19

Dr. Krishna Kavi Dr. Krishna Kavi, Professor in the Department of Computer Science and Engineering, will present a CSE Department Seminar on Friday, November 19, at 11:00 a.m. in the main department conference room, F223. His presentation is SDF - An Architectural Framework for Multicore Processors.

The topic of the seminar will be multicore and multithreaded architectures which have received considerable attention over the past few years. However, current implementations rely on conventional programming paradigms and require complex static or dynamic transformations of programs into concurrent threads. This requires either complex hardware to detect data and control hazards to reorder and issue multiple instructions, or complex compiler techniques.

Our Scheduled Dataflow (SDF) architecture differs from other multithreaded and multicore architectures in the following ways: i) our programming paradigm is based on dataflow, which reveals inherent parallelism to the hardware, thus reducing the hardware complexity significantly, ii) our processor cores are very simple and support fine-grained parallelism, iii) we completely decouple all memory accesses from execution pipeline and iv) our architecture supports speculative and transactional memory synchronizations. In this talk Dr. Kavi will present the SDF architecture and show how the model can be used to develop scalable multicore processors.

NSL members
NSL members (Back L-R): Mohamed Fazeen, Srikanth Jonnada, Dr. Ram Dantu, Enkh-Amgalan Baatarjav, Kalyan Pathapati Subbu, Neeraj Gupta;
(Front L-R): Brett McCormick, Vikram Chandrasekaran, Chris Barthold, Brandon Gozick.

The Network Security Lab (NSL), under Dr. Ram Dantu's supervision, has been actively involved in research projects in varied topics ranging from pervasive computing, context-aware computing, biomedical application development to privacy in online social networks and security in VoIP networks. Below are some highlights of the NSL:

Santi Phithakkitnukoon, a former Ph.D. student who is currently a Postdoctoral Research Fellow at MIT SENSEable City Lab, received acceptance of two of his papers "Behavior Based Call Predictor for a Smart Phone", and "ContextAlert: Context-Aware Alert Mode Control for a Mobile Phone" in ACM Transactions on Autonomous and Adaptive Systems and International Journal of Pervasive Computing and Communications respectively.

Huiqi Zhang, successfully defended his dissertation "Quantifying reciprocity in social networks" in April 2010. His work "Socioscope: Human Relationship and Behavior Analysis in Mobile Social Networks", was accepted in IEEE Transactions on Systems, Man and Cybernetics, Part A: Systems and Humans. He also had two papers "Smart Phone: Predicting the Next Call" and "Event Detection based on Call Detail Record" accepted and published in the proceedings of The 14th Pacific-Asia Conference on Knowledge Discovery and Data Mining 2010.

Vikram Chandrasekaran successfully defended his Master's thesis titled "Measuring Vital Signs Using Smart Phones" on October 15, 2010. His work involved using mobile phones for measuring vital signs of a human such as heart rate, blood pressure and respiratory patterns. He also developed a next generation 911 remote media control system that could reduce the communication time between the 911 dispatcher and a person needing help in a distress situation.

Mohamed Issadeen Mohamed Fazeen, Ph.D. student in CSE, is focusing on road safety using smart phones and brain computer interfaces (BCI). He is developing techniques that can measure changes in human motion using multiple sensors in a smart phone and human emotion using brain computer interface. He currently has a paper "Safe Driving Using Mobile Phones", under revision for IEEE Transactions on Intelligent Transportation Systems.

Enkh-Amgalan Baatarjav, a Ph.D. student in CSE, is currently a teaching assistant. His research interest is privacy in online social networks. His current work involves sampling large social networks to get representative data set and finding social closeness based on context of messages exchanges.

Kalyan Pathapati Subbu, Ph.D. candidate in CSE, is currently a teaching assistant. He is working on an Indoor localization and Navigation system using mobile phones as part of his dissertation. He is also developing new methods for sensing data using embedded sensors in mobile phones. He currently has a paper "Magnetic Maps for Indoor Navigation" along with Brandon Gozick under revision for IEEE Transactions on Instrumentation and Measurement.

Neeraj Gupta, a Ph.D. student, is working on Next Generation 911 system. The system incorporates new telecommunications technologies of Voice over IP and he is trying to study the problems that it creates. For example, when a 911 operator receives a call from someone using VoIP, the location of the caller may not be easily accessible. In such a situation, it is hard for emergency responders to help. His paper titled "Next Generation 9-1-1: Architecture and challenges in realizing an IP-multimedia-based emergency service", has been accepted in the Journal of Homeland Security and Emergency Management. Mr. Gupta, a Teaching Fellow for the CSE Department, is teaching CSCE 1040.001 this semester.

Srikanth Jonnada is a graduate student with specific interests in mobile and network programming. As part of his Master's thesis, he is working on exact localization for obtaining heartbeat and pulse readings using a mobile phone.

Brandon Gozick is pursuing his Master's in CSE starting Fall 2010. He is working on different projects like indoor navigation system using smart phones and drunk driving detection using smart phones. He mainly focuses on Android application development.

Christopher Barthold is a physics senior working on developing mathematical models for orientation detection of mobile phones. In particular, he is trying to understand the motion changes while a phone is inside a user's pocket and how the built-in sensors see the world around it.

Brett McCormick, undergraduate student in Computer Science, is currently working on learning about computer network administration at NSL. He was in Washington, D.C. recently to receive an award from the NSF called "Advanced Technological Education Student Award for Excellence" for his work with his two-year school, Collin Community College, and the ATE center called Convergence Technology. Brett is also a journalist for the College of Engineering. You can read his blog here.

Dr. Paul Tarau presents two papers

Dr. Paul Tarau

In July 2010, Dr. Paul Tarau presented two papers: "Declarative modeling of finite mathematics" at the 12th International ACM SIGPLAN symposium on Principles and Practice of Declarative Programming held at Castle Hagenberg in Austria, and "A Unified Formal Description of Arithmetic and Set Theoretical Data Types" at the Intelligent Computer Mathematics Symposium, Calculemus 2010 in Paris, France. In September 2010, Dr. Tarau presented the paper "On Arithmetic Computations with Hereditarily Finite Sets, Functions and Types" at the 7th International Colloquium on Theoretical Aspects of Computing, ICTAC 2010 in Natal, Brazil.

Together with his paper "Everything Is Everything Revisited: Shapeshifting Data Types with Isomorphisms and Hylomorphisms" recently published in the journal "Complex Systems" and the paper "Hereditarily finite representations of natural numbers and self delimiting codes" presented at the "Mathematically Structured Functional Programming workshop" in Baltimore, these papers are part of a new research thread, at the intersection of foundational aspects of computer science and computational mathematics, that has recently received NSF support.

Dr. Tarau is also looking for a brave new Ph.D. student ready for the fairly steep learning curves of this high risk (but possibly high reward) line of research in theoretical computer science, with at least one year of support secured starting in Spring 2011.

News for Alumni

Alumni Focus

CSE Alumni Travis Coomer

Travis Coomer graduated from UNT in 1983 with a B.S. in Computer Science. Within days of graduation, Travis began working for LTV Aerospace in Grand Prairie, TX as a missile system software engineer. Twenty seven years later, Travis is still with the company (now Lockheed Martin Missiles and Fire Control) and was recently promoted to Vice President of Technical Operations and Applied Research.

In his first assignment, Travis was lucky enough to land on an experimental missile program called Short Range Homing Interceptor Technology. The objective of the program was to develop a missile that could shoot down an incoming ballistic missile with skin-to-skin contact. "Shooting down a bullet with a bullet" was how it was often described. His first assignment was to develop the code for the missile's autopilot – quite a challenge given that he had never heard of a missile autopilot and these were the days before the Internet so Googling for help was out of the question. In time, and with the helpful guidance of some seasoned systems engineers, the task was completed successfully – step one of a long career.

Travis remained with this missile effort as it progressed through several iterations of increasing capability and his interest turned to the launcher side of the missile business as he became lead software engineer for the launcher programs. These missile systems were wildly successful in their demonstrations and ultimately ended up becoming the PAC-3 missile system – the same missile system currently fielded to protect our armed forces around the world and rapidly being purchased by other friendly nations to protect their soldiers and home lands from enemy attack.

Although the CS degree from UNT got Travis in the door as a software engineer, his interest in looking at systems from a broader view soon led him to the integration labs where he learned to work across functional lines with the electrical and systems test engineering teams and ultimately became a part of the field team supporting multiple missile launch efforts at White Sands Missile Range. The opportunity to be a part of the launch team and be an eye witness to the successful culmination (read "boom") of such a complex effort was the highlight of this young engineer's career.

Subsequent assignments included support of the PAC-3 seeker captive carry tests (which included many nauseous hours of flying around in a bumpy C-130 while tracking F-16s as "targets"), managing multiple software efforts, being a functional section manager overseeing the software development efforts across all programs, and eventually being named the Director of Software Engineering for all Dallas based efforts.

In 2007 Travis was named the Director of Functional Engineering Management which expanded his responsibility to include oversight of all the engineering disciplines (systems, mechanical, electrical, software, test, and product support) for both the Dallas and Orlando, FL operations. Needless to say, the workload and travel expanded as well.

Although many years have passed and the memories of UNT have become somewhat faded, Travis would like to thank Denis Conrady, Tom Irby, Don Retzlaff, Jim Poirot, John Sharp, Susan Rulon, and Kathleen Swigger for their guidance through the CS curriculum.

Student News

Two students defend Ph.D. Dissertations

Garima Thakral's Ph.D. defense

Garima Thakral successfully defended her dissertation "Process-Voltage-Temperature Aware Nanoscale Circuit Optimization" in September 2010. In the picture above are (L-R) committee member Dr. Elias Kougianos, associate professor in the Department of Engineering Technology; Dr. Saraju P. Mohanty, major professor and associate professor in the Department of Computer Science and Engineering; Garima Thakral; Dr. Murali Varanasi, Chair of the Department of Electrical Engineering; and Dr. Armin Mikler, associate professor in the Department of Computer Science and Engineering.

Dissertation Abstract: Embedded systems are targeted towards portable applications and are desired to have low power consumption because such portable devices are typically powered by batteries. During memory accesses such systems such as laptops, cell phones media players, etc. consume a significant amount of power which affects the battery life. Therefore, efficient and leakage power saving cache designs are needed for longer operation of battery powered applications. Design engineers have limited control over certain parameters of the circuit and hence face numerous challenges that the process technology imposes on Static Random Access Memory (SRAM) circuit design.

As the process technology scales down deeper into the nanometer regime, the push for high performance and reliable systems becomes even more challenging. As a result, developing low-power designs, while maintaining better performance of the circuit, becomes a challenging task. Furthermore, a major need for accurate analysis and optimization of various forms of total power dissipation and performance in Nano-CMOS technologies, particularly in SRAMs, is another critical issue to be considered.

This dissertation proposes power-leakage and Static Noise Margin (SNM) analysis and methodologies to achieve optimized Static Random Access Memories (SRAMs). Alternate topologies of SRAMs, mainly 7-Transistor SRAM, are considered as a case study throughout this dissertation. The optimized cache designs are Process-Voltage-Temperature (PVT) tolerant and consider individual cells as well as memory arrays.

Tamara Scneider's Ph.D. defense

Tamara Schneider defended her dissertation "A Framework for Analyzing and Optimizing Regional Bio-emergency Response Plans" in October 2010. Her committee members are (L-R): Robert Renka, professor in the CSE Department, Armin Mikler, major professor and associate professor in the CSE Department; Tamara Schneider; Chetan Tiwari, assistant professor in the Geography Department; Rada Mihalcea and Yan Huang, both associate professors in the CSE Department.

Dissertation Abstract: The presence of naturally occurring and man-made public health threats necessitate the design and implementation of mitigation strategies, such that adequate response is provided in a timely manner. Since multiple varieties, such as geographic properties, resource constraints, and government mandated time-frames must be accounted for, computational methods provide the necessary tools to develop contingency response plans while respecting underlying data and assumptions.

A typical response scenario involves the placement of points of dispensing (PODs) in the affected geographic region to supply vaccines or medications to the general public. Computational tools aid in the analysis of such response plans, as well as in the strategic placement of PODs, such that feasible response scenarios can be developed. Due to the sensitivity of bio-emergency response plans, geographic information, such as POD locations, must be kept confidential.

The generation of synthetic geographic regions allows for the development of emergency response plans on non-sensitive data, as well as for the study of the effects of single geographic parameters. Further synthetic representations of geographic regions allow for results to be published and evaluated by the scientific community. This dissertation presents methodology for the generation of synthetic geographic regions.

Taiwan Experience

by Tomislav (Tommy) Janjusic

Tommy Janjusic in Taiwan

In Spring 2010, I had the pleasure of spending five months abroad conducting research and collaborating with a research group at the National Chiao Tung University in Taiwan.

The trip was part of a sabbatical visit by my major professor Dr. Krishna Kavi. Our goals were to learn as much as possible from our new colleagues, exchange ideas and to establish future research collaborations.

Taiwan, also known as Formosa (Beautiful Island in Portuguese), is a small island sitting just off of the southeastern coast of China. The island is roughly 13,892 square miles which is about 19 times smaller than the state of Texas. Despite its small size, it is home to nearly 23 million people which is just under a million people less than Texas. Talk about population density!

National Chiao Tung University (NCTU) is located in the city of Hsinchu, a highly industrial and extremely populated urban area in the northwest of the country. To the northeast of Hsinchu is Taipei, Taiwan's capital city and major industrial, financial and cultural hub. It is home to the second tallest building in the world, Taipei 101.

NCTU is Taiwan's oldest and one of the most prestigious universities. It is conveniently located near Hsinchu's Science Park, an area commonly known as the Silicon Valley of Asia. Thus it comes as no surprise that the university draws great benefit from the surrounding companies through collaborations and partnerships.

After arriving, I settled in an apartment complex roughly 20 minutes walking distance from the main campus. At first I was reluctant to wander around the city on foot. For one, most street signs are in Chinese and relatively few people outside the university speak English, and I didn't trust myself to find my way back. The first few days I took the bus to and from the main campus. However, soon enough I was eager to explore and expand my cultural horizons so I decided to take the bold step and walk to main campus. I thought I memorized the way, but commercial advertisements are piled up on top of each other to the point where everything looks the same and different at the same time. In other words I didn't even take a few steps and I was already lost. I wandered around for about an hour before I decided to purchase a map. I thought nothing can go wrong now that I have a map and my mood quickly changed from bad to worse when I realized that the map is in fact completely in Chinese. At this point it was a desperation move where I literally stopped every person on the street asking if they spoke English and if they could give me directions. In the end it took me a little over 3 hours to walk a distance that usually takes 15 minutes. That had to be some type of a record!

The group at NCTU that I worked with is the Computer Systems Group. Similar to our group they are comprised of students and professors conducting research in various aspects of computer architecture and compilers. However, unlike our group they are quite large with as many as 15-20 Master's and 5 Ph.D. students. Their weekly meetings are in fact sessions of various projects and one can tangibly learn from attending the meetings. Also, unlike in our group, the Ph.D. and Master's student relationship is more that of a mentor-mentee type. The cohesion in their group is noticeable, and the student interest led many times to new ideas and insight into my work as well as their work.

I found the Taiwanese hospitality to be considerable. The students and professors alike went out of their way to be accommodating. Likewise I had the pleasure to travel around the country and see the life outside the urban areas. While west Taiwan remains the urban industrial area, east Taiwan offers amazing natural sceneries. One cannot go about Taiwan and not notice the cultural richness this country offers. My trip to Taiwan was truly a memorable one, and I would strongly encourage anyone given the chance to visit Taiwan.

Homecoming 2010

UNT Homecoming 2010
Engineering Ambassadors at Homecoming (L-R): Oscar Angulo, Taylor Fisher and CSE student Brett McCormick.

More than 50 guests visited the College of Engineering tailgating tent in Mean Green Village adjacent to Fouts Field Stadium on Saturday, October 16, for Homecoming 2010. Several guests noted that this would be our last season gathering outside Fouts Field since the new football stadium will be ready for the 2011 season. Student Ambassadors answered questions and compared notes with alumni. A few recent graduates visited with Dean Tsatsoulis and Rick Reidy, interim Chairman of the Engineering Technology department.

Maybe nostalgia attracted alumni whose average graduation date was more than 20 years ago. Several alums brought their children who are in high school and considering attending UNT. Everyone enjoyed the student research presentations from Computer Science and Engineering, Electrical Engineering and Materials Science and Engineering.

Food attracted vegetarians and carnivores alike as options for both were available from the Italian cuisine buffet. Industry representatives found the level of energy and enthusiasm remarkable compared to their experience with "tailgating" events.

New Advanced Materials Analysis Lab will benefit
CENG faculty and students

UNT Logo

The University of North Texas will build one of the most advanced materials analysis laboratories at any university when it begins construction of its new Nanofabrication Analysis and Research Facility (NARF) in November at UNT's Discovery Park. This new lab will benefit both faculty and students in the College of Engineering.

The new $6 million facility will integrate UNT's Center for Advanced Research and Technology (CART) with a new clean room that will allow scientists to synthesize and process samples of new materials and then test and examine them at the molecular and atomic levels using CART's 27 state-of-the-art instruments and microscopes. CART is one of the nation's most extensive facilities for powerful materials characterization and analysis.

Additionally, the adjacent location of UNT's state-of-the-art business incubators will add to the uniqueness of the facility by giving the start-up businesses convenient access to NARF equipment and resources to better advance research. For more information, read this UNT press release.

V. Lane Rawlins

On November 12, The University of North Texas System Board of Regents approved a recommendation from Chancellor Lee Jackson naming V. Lane Rawlins as the sole finalist for the presidency of the University of North Texas–the system's flagship campus in Denton.

Rawlins, the former president of Washington State University and the University of Memphis, has been serving a one-year appointment as UNT's president since May 14, 2010, following Phil C Diebel's brief service as UNT's interim president.

This board action begins the minimum 21-day period required by Texas law before the System regents can vote to officially appoint Rawlins to the UNT presidency. If confirmed by the board next month, Rawlins will become UNT's 15th president. For more information, see this UNT press release.

UNT opens new Life Sciences complex

Life Sciences Complex

In October 2010, the University of North Texas opened its new Life Sciences complex, located one block east of West Sycamore Street and Avenue C. The four-story, state-of-the-art research facility with 87,000 square feet of space will support and enhance UNT's rapidly growing research in life sciences and be used for biochemistry and molecular biology, developmental physiology, genetics and plant science.

The new building, which connects to the existing Biology Building, includes an open atrium space on the first floor with connector bridges on the second and third floors to allow integration of faculty and staff in the current Biology Building with those in the new facility.

The complex includes an aquatics laboratory for the study of a wide range of human health issues and marine conservation issues as well as four climate-controlled rooftop research greenhouses designed for technologically advanced plant science research.

The building is projected to receive gold-level Leadership in Energy and Environmental Design certification from the U.S. Green Building Council, which means the design, construction and operation meet strict environmental standards. This will be UNT's first LEED-certified building to open. Construction on the building began in October 2008.
