Military personnel are facing an increasing security threat posed by their smart phones and other mobile devices, argues an article on DefenseSystems.com. While the potential of mobile devices to leak personal secrets has been a cause for concern for all, the issue has the potential to be devestating for soldiers who could unwittingly leak crucial information to the enemy through compromised networks.

In the article, our very own Richard Forno, graduate program director for cybersecurity, shares his own concerns about cloud safety:

“One key area of emerging concern is data-in-motion within a cloud — i.e., ensuring that data is protected as it transits and/or exists in multiple servers at the same time, and by extension, the issue of ‘availability’ of data in a cloud environment,” Forno said. “The more moving parts you have to deal with, the easier it is to gum up the works, inadvertently cause self-inflicted problems, or make it easier for an adversary to do the same thing.”

Spectrum Wars: LightSquared vs. GPS

Professor Chuck LaBerge
Professor of the Practice, CSEE Dept/UMBC

11:30am-12:45pm Friday, 2 March 2012, ITE 231

The radio-frequency spectrum is a limited resource. Within the US, commercial use of the spectrum is administered by the Federal Communications Commission (FCC), while government use of the spectrum is administered by the National Telecommunications and Information Administration. Currently, the regulatory community is locked in a battle about spectrum utilization in the vicinity of 1.5 GHz. This struggle pits millions of users of GPS technology for position and time information against technical innovators desiring to bring 4G wireless communications to millions of users in underserved populations. So who wins the spectrum wars?

The talk will outline the technologies involved, and provide a time-line of the regulatory actions to date. There are some innovative things going on here, and some simple analysis will show why there are points of contention. A final resolution cannot be provided at this time, because the issue is currently an open discussion in FCC. And, as might expected, there are financial and political ramifications as well.

This talk will provide an interesting insight into how the 'real world' works.

Dr. LaBerge is Professor of the Practice of Electrical and Computer Engineering in the CSEE at UMBC, where he teaches a wide variety of courses ranging from Introductory Circuits to Error Correcting Codes. From 1975-2008, he was employed by Bendix, which became AlliedSignal, which became Honeywell through a series of corporate mergers. He retired in July 2008 as the Senior Fellow for Communications, Navigation, and Surveillance in Honeywell's Aerospace Research and Technology Center.

Dr. LaBerge has worked on precision landing systems and a wide variety of aeronautical radios and applications. He's recognized as an expert in issues involving interference to aeronautical systems. His technical, writing, and editorial contributions have received numerous citations from regulatory bodies, and he was the winner of the Best Paper of Conference at the 2000 IEEE/AIAA Digital Avionics Systems Conference.

Dr. LaBerge is a Senior Member of IEEE, a member of Tau Beta Pi, and an inductee in the Order of the Engineer. He received his BES-EE and MSE-EE, degrees, both with Honors, from The Johns Hopkins University and the PhD. in Electrical Engineering from UMBC. His three kids are older than his students.

Host: Prof. Joel M. Morris

Game enthusiasts of all stripes hunkered behind computer screens in the UMBC GAIM Lab for the 4th annual Global Game Jam—a fast-paced weekend where teams around the world conceive and creative video games around a common theme. The three-day event, which took place Friday, January 27th through the 29th, drew nearly forty participants ranging from undergraduate and graduate students, alumni, and even current game developers.

Dr. Marc Olano, professor of Computer Science and Electrical Engineering and Neal McDonald, assistant professor of Animation & Interactive Media, have been running the jam at the UMBC site since its inception four years ago. “It’s intense but I think people have a lot of fun,” says Olano, who is also the director of the Computer Science Program’s Game Development Track.

The weekend follows a strict itinerary. At 5 p.m. on Friday, a video keynote kicks off the competition and the secret theme is announced. From that point on, participants have until 3 p.m. on Sunday to complete a game from start to finish. Factor in eating and sleeping, and it’s not much time. “Three days is an extremely short period of time,” says Olano. “In terms of wall-clock time,” he says, “it’s a little less than two days.”

In previous years, themes included “As long as we’re together, there will always be problems,” or more simply, “extinction.” But this year, a theme was chosen that could be equally relatable to the nearly 11,000 participants from countries like Canada, Sweden, Brazil, France, Italy, Hungry, Israel, and Japan (to name a few). Instead of a phrase, this year’s theme was apicture: Ouroboros–a snake eating its own tail–which Wikipedia describes as a representation of “the perpetual cyclic renewal of life.”

Some teams were inspired by this idea of reincarnation, including the team responsible for Bit Exhaust, a game developed for the Microsoft Windows Phone platform. Reminiscent of Space Invaders, though graphically and conceptually more sophisticated, Bit Exhaust turns conquered foes into allies and visa versa. “What we took from the theme was rebirth and cyclic life,” reads the game description on the Game Jam Website. “Enemies and allies are constantly switching sides as you kill them and they die.”

Bit Exhaust was the recipient of an award from Next Century Corporation, whose sponsorship allowed the Global Game Jam to be a free (and catered) event for all participants.

Even Microsoft sweetened the deal with the promise of a free phone for teams who chose to develop games for their windows phone platform (not surprisingly, six of the ten teams opted to do just that). In addition, Microsoft offered up two prizes to phone-based games: second place to Bit Exhaust, and first place to Survive the Serpent, a literal take on the event’s theme. The 2-D maze game features a character who must escape being eaten by a snake by outsmarting it into biting its own tail.

Each year the People’s Choice Award is given to the game that’s voted the best overall by its peers. This year the winner was Snake ‘N Bake, a two-player game where a snake must help a cupcake make it to the oven before the tasty confection gets hit by a fireball.

Though individual sites—like UMBC—can offer prizes, Olano stresses that the Global Game Jam is not a competition. “They really want it to be more about cooperation than about competitiveness,” he says of the event’s sponsor, the International Development Association (IGDA). It’s not uncommon, he says, for teams to help each other out during the three-day fest.

Olano says he is definitely planning to host the Global Game Jam again next year, which will again put UMBC among other local hosts including Shady Grove, American University, and George Mason University. The Global Game Jam is the largest gam jam event in the world, according to its website. “This year there were 246 locations around the world,” says Olano, and the number will only grow.

Google is running an Android Camp this summer where 30 selected students will attend an all-expense-paid program at Google’s headquarters in Mountain View, California, July 22-28.

The camp will include an interactive and collaborative curriculum focusing on a practical introduction to developing applications for Android and will explore the concepts behind Android, the framework for constructing an application, and the tools for developing, testing, and publishing software for the platform. Students will also get the opportunity to enjoy technical talks by Googlers, and social activities around the Bay Area.

To be eligible, you must be a current freshman or sophomore majoring in Computer Science, Computer Engineering or related area and have at least a year of proven Java development experience.  The application deadline is March 11.

For more information and to apply, see the 2012 Google Android Camp site.

By the end of 2012, Google plans to unveil their latest addition to the tech world: a pair of android-based digital glasses, reports the New York Times. With a built in camera, the glasses will monitor the wearer’s surroundings and present them with relevant information about nearby businesses, or information about friends who might be nearby. Like smartphones, the glasses will harness third-party 3G or 4G for internet access. The glasses are being developed by the Google X team based out of a top-secret lab in Google headquarters where the company’s top-minds have been thinking up plans for futuristic products like space elevators and driverless cars.

Priced about the same as a smartphone—$250 to $600—the glasses are reported to have the rugged and futuristic look of a pair of Oakley Thump glasses. The proposed navigation system for the glasses will be a series of subtle head nods.

A PCWorld article shed a not-so-favorable light on the proposed Google product, saying that glasses could be potentially hazardous if worn while driving. The glasses, like other mobile devices, also raise questions about personal security and the potential of Google harnessing “Big-brother”-like influence over its customers. It’s likely, too, that the product is bound to cause concern about the health implications of having a small screen sitting only a few inches from your eye.

FSO-MANETs: Free-Space-Optical Mobile Ad-Hoc Networks

Dr. Murat Yuksel
Computer Science and Engineering
University of Nevada, Reno

1:00pm Monday 27 February 2012, ITE 325b, UMBC

The recent proliferation of wireless technologies and choices available to user applications has triggered a tremendous wireless demand, and wireless nodes are expected to dominate the Internet soon. Reports show that usage of mobile Web and WiFi by smartphones is increasing sharply, with more than 80% of their data consumption landing on WiFi points, and this statistic does not even include a major smartphone brand, the iPhone. Accommodating this exploding wireless demand with cellular capacity does not seem possible in the long run. As the radio spectrum (RF) spectrum is getting scarcer and saturated by recent innovations in attaining high spectral efficiency gains such as hierarchical cooperative MIMO, we urgently need innovations that will enable leveraging of new wireless spectrums and substrates in order to respond to the exploding mobile wireless traffic demand. Further, the capacity gap between RF wireless and optical fiber backbone speeds will remain huge because of the limited availability of RF spectrum. Enabling optical spectrum in wireless communications is the needed revolution for ultra-high-speed mobile ad-hoc networks (MANETs) of the future.

In this talk, I will present our work on exploring the potential for free-space-optics (FSO), a.k.a. optical wireless, in the context of very-high-speed mobile ad-hoc and opportunistic networking. We introduce basic building blocks for MANETs using FSO and present initial prototypes for multi-hop FSO building blocks and protocols operating under mobility. 3-D spherical structures covered with inexpensive FSO transceivers (e.g., LED/VCSEL and photo-detector pair) solve issues relevant to mobility and line-of-sight (LOS) management via availability of several transceivers per node. Such structures facilitate electronic LOS tracking (i.e., “electronic steering”) methods instead of traditional mechanical steering techniques used in FSO communications. By abstracting FSO directionality and LOS characteristics, our work also explores issues relating to routing and localization, and develops layer 3 protocols. FSO has been used at high-altitude communications, and this research enables FSO communications at lower-altitudes and in ad-hoc settings with redundancy of cheap optoelectronic components. This research also contributes to the new application of using solid-state lighting technology due to potential integration of illumination and communication functions in the same devices. Please refer to our project website for further information.

Brain-Computer Interface Technologies
in the Coming Decades (with Demonstration)

Dr. Kaleb McDowell
Translational Neuroscience Branch Chief
Army Research Laboratory

11:30-12:30 Friday, 24 February 2012, ITE 227, UMBC

As the proliferation of technology dramatically infiltrates all aspects of modern life, in many ways the world is becoming so dynamic and complex that technological capabilities are overwhelming human capabilities to optimally interact with and leverage those technologies. Fortunately, these technological advancements have also driven an explosion of neuroscience research over the past several decades, presenting engineers with a remarkable opportunity to design and develop flexible and adaptive brain-based neurotechnologies that integrate with and capitalize on human capabilities and limitations to improve human-system interactions. Major forerunners of this conception are brain-computer interfaces (BCIs), which to this point have been largely focused on improving the quality of life for particular clinical populations and include, for example, applications for advanced communications with paralyzed or "locked-in" patients as well as the direct control of prostheses and wheelchairs. Near-term applications are envisioned that are primarily task-oriented and are targeted to avoid the most difficult obstacles to development. In the farther term, a holistic approach to BCIs will enable a broad range of task-oriented and opportunistic applications by leveraging pervasive technologies and advanced analytical approaches to sense and merge critical brain, behavioral, task, and environmental information. Communications and other applications that are envisioned to be broadly impacted by BCIs are highlighted; however, these represent just a small sample of the potential of these technologies.

Kaleb McDowell (M'08-SM'11) was born in Frederick, MD, USA on July 10, 1970. He has a B.S in operations research and industrial engineering from Cornell University, Ithaca, NY, USA in 1992, an M.S. in kinesiology from the University of Maryland, College Park, MD, USA in 2000, and a Ph.D. in neuroscience and cognitive science from the University of Maryland, College Park, MD, USA in 2003.

He is currently the Chief of the Translational Neuroscience Branch and Chair of the Neuroscience Strategic Research Area at the U.S. Army Research Laboratory (ARL) in Aberdeen Proving Ground, MD, USA. Since joining ARL as a Research Psychologist in 2003, he has contributed to over 30 reviewed publications, and has led several major research and development programs focused on neuroscience, indirect vision systems and vehicle mobility. His current research interest focuses on translating basic neuroscience into applications for use by healthy populations in everyday, real-world environments.

Exploring the Web, Beyond Document Search

Professor Yi Chen
Computer Science, Arizona State University

1:00pm Friday 24 February 2012, ITE 325b, UMBC

Today we rely on Web Search Engines, like Google or Bing, to find relevant documents among trillions or quadrillions of documents on the Web. The Web also contains a vast amount of structured data in a variety of domains, such as travel, products, bibliographies, finance, and social networks. Current Web search engines and web database query interfaces are insufficient to satisfy the diverse search needs of web users. The information discovery processes are further complicated by the prevalence of uncertain data. At the same time, it is infeasible to request a web user to design clean databases and write precise SQL queries. In this talk, I will discuss the challenges, opportunities, and then some of the solutions that we have developed for empowering web users for effective information search on structured data. Furthermore, I will discuss how to enable successful social search so that complex computation tasks can be accomplished by leveraging social computing.

Yi Chen is an Associate Professor in Computer Science and an affiliate faculty in Biomedical Informatics at Arizona State University (ASU). She received her Ph.D. from the University of Pennsylvania and her B.S. from Central South University in 2005 and 1999, respectively. Her research interests include keyword search on structured data, learning uncertain data, workflow management and social computing, with applications in Web, social computing and healthcare. She is a general chair for SIGMOD'2012, a PC chair for KEYS’2009 and DBRank’2012. Yi Chen is a recipient of Outstanding Researcher Award in ASU CSE (2011), a Google Research Award (2011), IBM Faculty Award (2010) and an NSF CAREER Award (2009).
