Three Ph.D. students from the ebiquity lab have posters at the ACM Student Research Competition and General Poster Session of the 2012 Grace Hopper Celebration of Women in Computing conference. The GHC conference is the largest technical conference for women in computing and results in collaborative proposals, networking and mentoring for junior women and increased visibility for the contributions of women in computing. Conference presenters are leaders in their respective fields, representing industry, academia and government. Top researchers present their work while special sessions focus on the role of women in today’s technology fields.
The three ebiquity lab students with posters this year are:
Automation of Cloud Services lifecycle by using Semantic technologies,
Karuna Panda Joshi
We have developed a new framework for automating the configuration, negotiation and procurement of services in a cloud computing environment using semantic web technologies.We have developed detailed Ontologies for the framework. We have designed a prototype, called Smart Cloud Services, which is based on this framework and also incorporates NIST’s policies on cloud computing. This prototype is integrated with different cloud platforms like Eucalyptus and VCL.
A Knowledge-Based Approach To Intrusion Detection Modeling,
M. Lisa Mathews
Current state of the art intrusion detection and prevention systems (IDPS) are signature-based systems that detect threats and vulnerabilities by cross-referencing the threat/vulnerability signatures in their databases. These systems are incapable of taking advantage of heterogeneous data sources for analysis of system activities for threat detection. This work presents a situation-aware intrusion detection model that integrates these heterogeneous data sources and builds a semantically rich knowledge-base to detect cyber threats/vulnerabilities.
Unsupervised Coreference Resolution for FOAF Instances,
Jennifer Alexander Sleeman
Coreference Resolution determines when two entity descriptions represent the same real world entity. Friend of a Friend (FOAF) is an ontology about people and their social networks. Currently there is not a way to easily recognize when two FOAF instances represent the same entity. Existing techniques that use supervised learning typically do not support incremental processing. I present an unsupervised approach that supports both heterogeneous data and incremental online processing.

It’s very nice to see ebiquity alumna Akshaya Iyengar (MS, 2011) helping Wikipedia during its fund raising campaign. If you visit Wikipedia you might see her gracing a page you get, as I did just a minutes ago. See this screenshot and read her statement on why she has been donating to Wikipedia here. Her generosity has inspired me to contribute also.

Here’s a word cloud that visualizes the 200 most significant words extracted from over 400 papers from our research group over the past ten years. Significance was estimated by tf-idf where the idf data is from a collection of newswire articles (thanks Paul!). The word cloud was created with Wordle.

DARPA is developing a new component to track “quiet submarines” to be part of the Navy’s Anti Submarine Warfare toolkit and is using a software game to collect effective strategies for its use.
“Before autonomous software is developed for ACTUV’s computers, DARPA needs to determine what approaches and methods are most effective. To gather information from a broad spectrum of users, ACTUV has been integrated into the Dangerous Waters™ game. DARPA is offering this new ACTUV Tactics Simulator for free public download.
This software has been written to simulate actual evasion techniques used by submarines, challenging each player to track them successfully. Your tracking vessel is not the only ship at sea, so you’ll need to safely navigate among commercial shipping traffic as you attempt to track the submarine, whose driver has some tricks up his sleeve. You will earn points as you complete mission objectives, and will have the opportunity to see how you rank against the competition on DARPA’s leaderboard page. You can also share your experiences and insights from playing the simulator with others.”
This is a kind of crowdsourcing — leveraging the experiences of a large number of people playing a game. Applying various kinds of machine learning algorithms to the simulator data could be an effective way to train an autonomous tool for this task.

UMBC, SAIC, the National Cyber Security Alliance, the Tech Council of Maryland, and the Maryland Department of Business and Economic Development have joined to hold the Maryland Cyber Challenge and Conference on October 21-22, 2001. The event is designed to increase cyber awareness as a career choice in Maryland, improve the appreciation for cyber oriented curriculum in college and high schools, and convey cyber defense as a sport to increase interest in careers involving cyber security.
The competition will be divided into high school, collegiate and professional divisions. Qualifying rounds take place over the Internet between April and August 2011 using SAIC's Cyber Network Exercise System (CyberNEXS), a scalable training, exercise and certification system. The top eight teams in each division will meet at the MDC3 event in October for the final round followed by an award ceremony at UMBC. MDC3 participants will also be able to learn from and network with other cybersecurity professionals, researchers, and scholars at the conference, which will include presentations, a career fair and a vendor exhibition.
For more information see this press release and the SAIC MDC3 site.

UMBC will host the 2011 FIRST Lego League Maryland State Championship on Saturday February 26 in the UMBC Retriever Activities Center.
FIRST Lego League (FLL) an international competition for elementary and middle school students that is run by the FIRST organization with support by Lego. FLL teams use Lego Mindstorms kits to build small autonomous robots built with a limited number of sensors and motors that complete to perform predefined challenge given tasks.
"Guided by adult mentors and their own imaginations, FLL students solve real-world engineering challenges, develop important life skills, and learn to make positive contributions to society. FLL provides students age 9-14 with an opportunity to challenge their math and science skills in an internationally recognized competitive environment. FLL combines a hands-on, interactive robotics program with a sports-like atmosphere. Teams of up to 10 players focus on team building, problem solving, creativity, and analytical thinking to develop a well thought out solution to a problem currently facing the world – the Challenge."
The UMBC organizers, led by UMBC Mechanical Engineering Professor Anne Spence, need volunteers from the UMBC community to help on the tournament day as well as to help set up in on Friday. If you are interested in helping please register online. Volunteering to help in the Maryland FLL championship is a great way to help engage young people in science and technology and have some fun doing it.

China’s Tianhe-1A is being recognized as the world’s fastest supercomputer. It has 7168 NVIDIA Tesla GPUs and achieved a Linpack score of 2.507 petaflops, a 40% speedup over Oak Ridge National Lab’s Jaguar, the previous top machine. Today’s WSJ has an article,
“Supercomputers are massive machines that help tackle the toughest scientific problems, including simulating commercial products like new drugs as well as defense-related applications such as weapons design and breaking codes. The field has long been led by U.S. technology companies and national laboratories, which operate systems that have consistently topped lists of the fastest machines in the world.
But Nvidia says the new system in Tianjin—which is being formally announced Thursday at an event in China—was able to reach 2.5 petaflops. That is a measure of calculating speed ordinarily translated into a thousand trillion operations per second. It is more than 40% higher than the mark set last June by a system called Jaguar at Oak Ridge National Laboratory that previously stood at No. 1 on a twice-yearly ranking of the 500 fastest supercomputers.”
The NYT and HPCwire also have good overview articles. The HPC article points out that the Tianhe-1A has a relatively low Linpack efficiency compaed to the Jaguar.
“Although the Linpack performance is a stunning 2.5 petaflops, the system left a lot of potential FLOPS in the machine. Its peak performance is 4.7 petaflops, yielding a Linpack efficiency of just over 50 percent. To date, this is a rather typical Linpack yield for GPGPU-accelerated supers. Because the GPUs are stuck on the relatively slow PCIe bus, the overhead of sending calculations to the graphics processors chews up quite a few cycles on both the CPUs and GPUs. By contrast, the CPU-only Jaguar has a Linpack/peak efficiency of 75 percent. Even so, Tianhe-1A draws just 4 megawatts of power, while Jaguar uses nearly 7 megawatts and yields 30 percent less Linpack.
The (unofficial) “official” list of the fastest supercomputers is TOP500 which seems to be inaccessible at the moment, due no doubt to the heavy load caused by the news stories above. The TOP500 list is due for a refresh next month.
