This is personal story about how high performance computing was developed at the NASA-Ames Research Center and elsewhere in NASA. There were people at Ames who were first class aerodynamic scientists and who could use computers. Thus, it was decided that some procurement short cuts were justified. We acquired computers in three quantum steps. First, in 1969, there was an IBM duplex 360/67 which was captured by a “midnight supply operation” from the Air Force. Next, in 1972, the ILLIAC IV at the University of Illinois became available because of an act of domestic terrorism and financial help from DARPA. Finally in 1975, there was one of Seymour Cray’s CDC 7600s, also from an Air Force source. In 1981, by which time Seymour Cray had his own company, a Cray 1S appeared at Ames, followed in 1984 by CDC Cyber 205 and a Cray X-MP/22. The last named machines were made available because of shameless earmarking by NASA Headquarters. However, confession being good for the soul, the NASA-Goddard Space Flight Center also benefited from the earmarking with twenty million dollar fund to develop a truly massively parallel computer, the Goodyear MPP with 16,000 processors, which was delivered in 1984. Now we are working with people at Ames on a quantum computer manufactured by D‐Wave Systems, Inc. The machine was installed at Ames last year and we are now working on various “benchmark” tests and developing operating systems for the machine. We believe that there is great promise for much more capable computing machines in this new quantum technology.

Data Analytics for Sustainability

Professor Katharina Morik
TU Dortmund University, Germany

11:00am-12:30pm, Thursday 22 May 2014, ITE 456, UMBC

Sustainability has many facets and researchers from many disciplines are working on them. Particularly knowledge discovery always considered sustainability an important topic (e.g., special issue on data mining for sustainability in Data Mining and Knowledge Discovery Journal, March 2012).

• Environmental tasks include risk analysis concerning floods, earthquakes, fires, and other disasters as well as the ability to react to them in order to guarantee resilience. The climate is certainly of influence and the debate on climate change received quite some attention.
• Energy efficiency demands energy-aware algorithms, operating systems, green computing. System operations are to be adapted to a predicted user behavior such that the required processing is optimized with respect to minimal energy consumption.
• Engineering tasks in manufacturing, assembly, material processing, and waste removal or recycling offer opportunities to save resources to a large degree. Adding the prediction precision of learning algorithms to the general knowledge of the engineers allows for surprisingly large savings.

Global reports on the millennium goals and open government data regarding sustainability are publicly available. For the investigation of influence factors, however, data analytics is necessary. Big data challenges the analysis to create data summaries. Moreover, the prediction of states is necessary in order to plan accordingly. In this talk, two case studies will be presented. Disaster management in case of a flood combines diverse sensor data streams for a better traffic administration. A novel spatiotemporal random field approach is used for smart routing based on traffic predictions. The other case study is in engineering and saves energy in the steel production based on the multivariate prediction of the processing end-point by the regression support vector machine.

PhD Dissertation Proposal

Learning and Executing Energy Efficient, Context-Dependent
Rules for Privacy and Security Management on Mobile Devices

Prajit Kumar Das

8:00am Friday, 16 May 2014, ITE325b

There are ongoing security and privacy concerns around mobile platforms that are increasingly being used by citizens. For example a newly discovered security flaw in WhatsApp that allows hackers using a malicious app to read chat messages stored on the SD card. The Brightest Flashlight application was reported to have logged precise location and a unique user identifier, which have nothing to with its intended functionality. Current mobile platform privacy and security mechanisms are limited to an initial installation phase permission acquisition method. In addition to that, the permissions are of the all or none form. This means that either the users accept all the permissions requested by the mobile app or they cannot use the app in question. Even if permissions were not structured as such, typically, users do not understand the permissions being requested or are too eager to use the application to even care to read them. These issues are present in all major mobile operating systems. Given the penetration of mobile devices into our lives, a fine-grained context-dependent security and privacy control approach needs to be created.

We propose a framework that will allow us to learn the privacy and security rules for a particular user, on their mobile devices. We do this by employing a simple user feedback mechanism. The rule learning framework consists of a “learning mode” where it observes and learns from user behavior and a “working mode” where it implements the learned rules to protect user privacy and provide security. The rules are represented to the user in plain English using an easily understandable construct. The rules are internally written in a logic based language and using Semantic Web technologies. The antecedents of the rules are context elements that are derived from an ontology using a query engine and an inference mechanism. The main contributions of our work include learning modifications to current rules and learning new rules to control the data flow between the various data providers on the user’s mobile device, including sensors and services and the consumer of such data. The privacy and security rule execution consumes significant energy due to the context detection. We create an energy model that allows us to make energy cost optimizations with regards to rule execution. We use a three-fold solution for achieving the said energy cost optimizations.

Distributed protocols for connectivity restoration
in damaged wireless sensor networks

Yatish K. Joshi

1:00pm Monday, 12 May 2014, ITE325b, UMBC

Decreasing costs and increasing functionality of embedded computation and communication devices have made Wireless Sensor Networks (WSNs) attractive for applications that serve in inhospitable environments like battlefields, planetary exploration or environmental monitoring. WSNs employed in these environments are expected to work autonomously and extend network lifespan for as long as possible while carrying out their designated tasks. The harsh environment exposes the individual nodes to q high risk of failure, which can potentially partition the network into disjoint segments. Therefore, a network must be able to self-heal and restore lost connectivity using available resources. The ad-hoc nature of deployment, harsh operating environment and lack of resources makes distributed approaches the most suitable choice for recovery.

Most solution strategies for tolerating the failure of multiple collocated nodes are based on centralized approaches that pursue the placement of additional relays to form a connected inter-segment topology. While they are the ideal solution for dealing with simultaneous multi-node failures, they need to utilize the entire network state to determine where and how recovery should occur. In addition to the scalability concern of these approaches, controlled placement of stationary relays in remote and inhospitable deployment area may not be logistically feasible due to resource unavailability and would not be responsive due to the delay in transporting the resources to the area. Space exploration is an example of those WSN applications in which placement of stationary relays is not practical.

In this proposal, we tackle the problem of connectivity restoration in a partitioned WSN in a distributed manner. We consider multiple variants of the problem based on the available resources and present novel recovery schemes that suit the capabilities and count of existing nodes.

Recoloring Web Pages For Color Vision Deficiency Users

Vikas Bansal

11:00am Thursday, May 8, 2014, ITE346, UMBC

Color vision begins with the activation cone cells. When one of the cone cells dysfunction, color vision deficiency (CVD) ensues. Due to CVD, users become unable to differentiate as many colors a normal person can. Lack of this ability results in less rich web experience, incomprehension of basic information and thus frustration. Solutions such as carefully choosing colors while designing or recolor web pages for CVD users exist. We first present the improvement in the time complexity of an existing tool SPRWeb to recolor web pages. After that we present our tool which explores the foreground-background relationship between colors in a web page. Using this relationship we propose an algorithm which preserves naturalness, pair-differentiability and subjectivity. In the last part, we add an additional step in to algorithm to ensure that the contrast in the parsed color pairs meets the required W3C guidelines. In evaluation, we found that our algorithm does significantly better in preserving pair-differentiability and produces lower total cost solutions than SPRWeb. Quantitative experimentation of modified algorithm shows that contrast ratio in each replacement pair is more than 4.5 as required for readability.

3:00pm Tuesday, 29 April 2014, ITE 456, UMBC

Delivering on the commitment in the President’s Climate Action Plan, the White House recently launched the Climate Data Initiative — a broad effort to leverage the Federal Government’s extensive, freely- available climate-relevant data resources to advance awareness of and preparedness for climate change impacts. This effort will help give communities across America the information and tools they need to plan for current and future climate impacts. Data from NOAA, NASA, the U.S. Geological Survey, the Department of Defense, and other Federal agencies was recently launched on climate.data.gov. Data and innovation challenges issued by public, private, nonprofit, and other organizations can help catalyze new, data-driven solutions that help communities understand and build resilience to climate change. NOAA and NASA recently announced an innovation challenge calling on researchers and developers to create data-driven simulations to help plan for the future and to educate the public about the vulnerability of their own communities to sea level rise and flood events.

Mr. Eric Letvin PE, Esq, is the Director of Hazard Mitigation and Risk Reduction Policy within the National Security Council in the Executive Office of the President. He coordinates the development and effective delivery of mitigation capabilities identified in the National Preparedness Goal, such as threat and hazard identification, risk and disaster resilience assessment, planning, and long-term vulnerability reduction.

When at NIST, Mr. Letvin is the Disaster and Failure Studies Program Director within NIST’s Engineering Laboratory. Mr. Letvin provides national coordination for conducting field data collection studies. He is also responsible for creating and maintaining a repository related to hazard events (earthquakes, hurricanes, tornadoes, windstorms, community-scale fires in the wildland-urban interface, structural fires, storm surge, flood, tsunami) and human-made hazards (accidental, criminal, or terrorist), the performance of the built environment during hazard events, associated emergency response and evacuation procedures.

Before coming to NIST, Mr. Letvin was Leader of Infrastructure Research and Resiliency in the Homeland Security Group of URS. He has participated in numerous post-disaster studies including the bombing of the Murrah Building in Oklahoma City, and Hurricanes Opal, Ike and Katrina.

ACTIVE Center Open House

4:00-5:00pm Monday, 28 April 2014 in ENGR 231

The ACTIVE Center (Engineering 231) is a new classroom that was created by the CSEE Department with support from the Hrabowski Fund for Innovation, BAE Systems, and Northrup Grumman. The ACTIVE Center is designed to facilitate active student learning and laptop-based laboratory activities, and features movable furniture and whiteboards, a smart projector, and flat-panel displays around the room. We are also developing and documenting a “virtual environment” for the classroom, by creating “design patterns” for how computing technology can be used in this type of space to facilitate student learning.

The classroom came online in February 2014, and four pilot courses are currently being offered in the space. On Monday, April 28, we will hold an open house and presentation in the ACTIVE Center to show the campus community how an intentionally designed classroom space can increase student engagement and improve learning outcomes. The open house will include a presentation by Dr. Marie desJardins, a Hrabowski Academic Innovation Fellow and lead PI for the ACTIVE Center project, and a Q&A session with instructors and students who are currently teaching and learning in the ACTIVE Center. We will share best practices for developing and using similar teaching spaces, and will present the current policy for requesting to use the space for future classes.

Please note that no food or drink (other than covered containers of water) are permitted in the ACTIVE Center, but light refreshments will be provided in the hallway following the presentation.

Capacity is limited, so please RSVP. For more information, contact Marie desJardins (Sorry, you need javascript to view this email address. ).
