Hiring Students for Summer Text Mining Project

A new, interdisciplinary research project offers a total of five positions to graduate or undergraduate students from multiple disciplines who exhibit the right combination of initiative, skills and reliability. The project investigates undergraduate teaching at UMBC, and is led by the combined expertise of the Shriver Center, Interdisciplinary Studies Program and the Honors College. The students will work as an integrated, interdisciplinary team, and may expect to expand their own knowledge, skills and experience as a result. UMBC graduate students and exceptionally qualified undergraduate students will be considered.

A group of Academic and Student Affairs Division faculty and staff are working to better track, assess, strengthen and increase, and recognize and reward applied learning experiences across the UMBC Campus. In FY15, this group’s work has focused on creating a plan for assessing the impact of applied learning experiences (broadly defined) on students’ affective development.

Each position offers partial summer support funded by a Hrabowski Fund for Innovation: Implementation and Research grant.

80 hours (may span across 4-8 weeks depending on availability-no more than 20 hrs/week)

Stipend of $1150

The five graduate students we seek will have a background in the following skills/disciplines: Information Systems; Computer Science; Human Centered Computing; Instructional Systems Design; Applied Mathematics; Statistics; Human Services Psychology; Applied Sociology; Education; Language, Literacy & Culture; and Public Policy.

The project aims to continue for a minimum of three years, expanding subject to further successful funding. Students who perform well may be invited to extend their role.

One goal is to explore, through written student feedback, how diverse courses have contributed to their perception of growth in key attributes.  This first summer of the project will look at pilot data, exploratory analysis of scrappy, inconsistent, self-reported text, in order to figure out how to collect better, more uniform data in the Fall semester. One of the skill sets we wish for in the team would be a computer scientist able to mine text to seek the suggestion of themes, patterns or clues to what we would need to ask to get such patterns more clearly in the future.

All interested candidates should send a letter of interest, resume with references, and a statement with general summer weekly availability (e.g., Monday, Wednesdays & Fridays from 9am – 2pm) to Michele Wolff at by Wednesday, June 24.  Exceptionally qualified undergraduate students will also be considered.

Robotic assistive devices for independent living

Accessibility symbol

CSEE PhD student Kavita Krishnaswamy and Prof. Tim Oates write about their research using brain-computer interfaces and speech recognition tools to control robotic to assist individuals with reduced muscular strength. The piece, Robotic assistive devices for independent living, appeard in Robohub, "a non-profit online communication platform that brings together experts in robotics research, start-ups, business, and education from across the globe."

They describe their motivation as follows.

"One of the most craved aspects of the human experience is to be independent: the abilitiy to take care of one's self establishes a sense of dignity, inherent freedom, and profound independence. Our goal is to bring robotic assistive devices into the real world where they can support individuals with severe disabilities and alleviate the workload of caregivers, with the ultimate vision of helping people with severe physical disabilities to achieve physical independence without relying on others. As robotic assistive devices become ubiquitous, they will enable people with severe physical disabilities to confidently use technology in their daily lives, not just to survive, but to flourish."

They demonstrated the feasibility of integrating a brain-computer interface with speech recognition for self-directed arm repositioning tasks through a robotic interface for repositioning the simulated arm of an avatar using a Emotiv Epoc headset and Dragon NaturallySpeaking voice recognition software.

PhD proposal: Real-time Spectral Rendering of Atmospheric Optical Phenomena, 2pm 6/10

Ph.D. Dissertation Proposal

Real-time Spectral Rendering of Atmospheric Optical Phenomena

Ari Blenkhorn

2:00pm Wednesday, 10 June 2015, ITE 352

Glories, rainbows, and coronas are colorful atmospheric effects which occur when sunlight interacts with cloud droplets. Adding these effects to digital cloud environments will provide increased realism and a greater sense of immersion. Furthermore, these phenomena are the subject of active scientific research.  In both communities, high-resolution real-time rendering is desirable.

The color distribution of these phenomena is typically calculated using the Mie scattering theory, Debye series, or Airy theory. The calculations give the intensity of a single wavelength of light at a single scattering angle. They must be repeated for all desired wavelengths at all desired pixels of the final image.

I propose accelerating the calculations by using general-purpose GPU computing to transform a single-threaded, CPU-based Mie scattering application into a collection of highly-parallel GPU calculations.  I also propose to reduce the number of wavelengths required by using importance sampling, a monte-carlo selection method which concentrates the computing resources on the wavelengths belonging to the most important regions of the visible spectrum.

Planned work includes development of both numerical and perceptually-based image quality metrics, of interest to optical physicists and interactive application developers, respectively. These metrics will guide development of the GPU kernel parallel structure and the selection of a suitable estimator for importance sampling.

Committee: Drs. Marc Olano, Penny Rheingans, Curtis Menyuk, Matthias Gobbert (Mathematics), Raymond Lee (USNA)

NSF site features CSEE Ph.D. student Kavita Krishnaswamy

UMBC CSEE Ph.D. student Kavita Krishnaswamy was featured in an NSF article Balancing life, health and research.

Balancing life, health and research, graduate student perseveres to increase access for persons with severe disabilities.

Kavita Krishnaswamy's doctoral dissertation defense at the University of Maryland, Baltimore County (UMBC), was fairly typical. Dissertation committee, doctoral candidate, explanatory slides, questions from the committee.

When it was over and time to deliberate, Tim Oates, Kavita's advisor, asked her to leave the room. Because Kavita delivered her presentation via a Beam Smart Presence System (BeamPro), she powered down the computer screen beaming her into the meeting.

This was business as usual for the computer science student whose research involves developing robotic prototypes to transfer, reposition and perform personal hygiene tasks for those with severe disabilities. She is also studying how to improve control over robotic interfaces for these individuals. Her tool kit includes elements of machine learning, artificial intelligence, brain-computer interfaces and other communication technologies.

You can read the rest on the NSF Discovery site.

CSEE research group demonstrates smart fabric for gesture recognition

inviz demonstration

CSEE Ph.D. student Alexander Nelson and faculty Ryan Robucci and Nilanjan Banerjee participated in the monthly TechBreakfast MeetUp where they demonstrated the research on developing 'invisible' sensing systems that can be embedded into fabrics.

Their Inviz system, developed in the UMBC Eclipse cluster of laboratories,  uses textile-based capacitive sensor arrays and micro-doppler radars embedded into bed sheets, pillows, wheelchair pads, and clothing, for environmental control and physical therapy for such paralysis patients. The sensors detect gestures regardless of evolving environmental and patient conditions and provides explicit real-time feedback to the user. Using low-cost and ultra-low power capacitive sensing and micro-radars built into headgear, the Inviz system can reduce hospital visits and therapy costs.

You can read more about the work in a paper that was awarded the best demonstration runner-up prize at the 2015 conference on Pervasive Computing and Communications (PerCom).

CyberDawgs take first place at Kaizen Capture the Flag event

Earlier this week, UMBC CyberDawg Christopher Gardner took first place out of approximately fifty competitors at Booz Allen Hamilton's Kaizen Capture The Flag event held at the Jailbreak Brewing Company in Laurel, MD.

The event focused around navigating through a series of progressively harder cybersecurity obstacles. The challenge's theme centered around a narrative that competitiors were assisting the FBI in finding and then defusing a bomb. Competitors needed to complete a series of increasingly harder challenges to locate clues and other information, such as examining an Android .apk to find a wireless access point password, finding the login page for an website's administration panel, and gaining access to a web server's log directory.

Congratulations again to Christopher and to all of the CyberDawgs who competed!

Interested in joining the CyberDawgs? Contact Julio Valcarcel () for more information — they’re always looking for new members heading into the 2015-2016 season!

Rick Forno comments on CareFirst data breach

In today's Baltimore Sun, CSEE's Rick Forno offers some early thoughts on yesterday's announced data breach at CareFirst, which affects 1.1 million insurance customers.

According to company officials, attackers gained access to names, birth dates, email addresses and insurance identification numbers. However, the database did not include Social Security or credit card numbers, passwords or medical information.

The information also could be sold on what is known as the dark web, parts of the Internet that cannot be found by search engines, and combined with other data, said Richard Forno, director of the University of Maryland, Baltimore County's graduate cybersecurity program.

"The information they got may or may not be useful directly, but it could help a bad guy get more clues about a person's identity," he said. "That could be useful to an adversary."

In many cases, data breaches can be larger than originally apparent, Forno added.

"As time goes on and the investigation continues, you never know if you'll find other leads that may change your initial assumptions," he said.
