Research and Research Careers in CS/IT/ECE

by Prof. Pankaj Jalote, Director, IIIT-Delhi

WHEN: 4-5PM, August 11, 2011

ABSTRACT: Most CS/IT/ECE (and other engineering disciplines as well) graduates will end up working for the many software companies in India. This is undoubtedly a very good career for most of the graduates. However, is it the right career for those who are at the top of the class or those who seek technical and technology challenges? This talk is for such graduates, who find the prospects of a "regular" software job not sufficiently satisfying. It discusses what research is, some aspects of a researcher, and the possibilities of a career in research in India - which besides being more challenging, is now getting more rewarding as well.

Innovations in Computing for Global Development at Microsoft Research India

by Dr. Ed Cutrell, Head, Technology for Emerging Markets group, Microsoft Research India

WHERE: Conference room, 3rd floor/Library
WHEN: 12-1PM, August 10, 2011

ABSTRACT: The Technology for Emerging Markets (TEM) group at Microsoft Research India seeks to address the needs and aspirations of people in the world's developing communities. Our research targets people who are just beginning to use computing technologies and services as well as those for whom access to computing still remains largely out of reach. Most of our work falls under the rubric of the relatively young field of Information and Communication Technology for Development (ICTD or ICT4D). By combining a variety of backgrounds and training, we are able to engage deeply with some of the complex problems associated with poverty and scarce resources. Our goal is to study, design, build, and evaluate technologies and systems that are useful for people living in underserved rural and urban communities  around the world. In this talk, I will give an overview of some of the recent work in the group, including:
1) a prototype pen-based system for rural microfinance
2) a phone broadcast system designed to assist an NGO serving urban sex workers, and
3) a mobile phone-based citizen news system for rural India.

Ed Cutrell manages the Technology for Emerging Markets (TEM) group at Microsoft Research India. Ed has been working in the field of human-computer interaction for more than a decade, studying everything from novel interaction techniques to interfaces for search and information retrieval. His current research focuses on Information and Communication Technologies for Development (ICT4D). In this work, he seeks to understand how people in the world's poor and developing communities interact with information technologies and explores new ways for technology to meet their needs and support socio-economic development. He is trained in cognitive neuropsychology, with a PhD from the University of Oregon.

Sensors and Sensor Network Applications for Nation and Society

by Prof. Prabhat Ranjan, Dhirubhai Ambani Institute for Information and Communication Technology, Gandhinagar (DA-IICT)

WHERE: Conference room, 3rd floor
WHEN: 1:30-2:30PM, August 9, 2011

Development of MEMS sensor, Wireless Communication and Low power miniaturized processors led to the possibility of Wireless Sensor Network(WSN) being used for a broad spectrum of applications. It has been nearly 15 years since we have promised wide spread use of WSN in
real life applications. However very few applications have seen regular deployment on long term basis in the real life scenario. More than 2 years of continuous outdoor deployment have not been reported.

We have been involved in a number of real life WSN projects for last 8 years, which are important to our Nation and Society. These cover wildlife tracking, planetary exploration, nuclear fusion, coral reef monitoring, assistive technology etc. While we try to use as much of common technology as possible in these projects, each one of them demands a set of new problems to be solved. In this talk, we share our experience in working on these systems and the way we have tried to approach these problems. We would also point out various open challenges that these have opened to WSN researchers. To take these projects to long term deployment stage needs a very dedicated effort over next few years and also requires a different approach in the way we work in academic community.

Prof. Prabhat Ranjan is Professor at Dhirubhai Ambani Institute for Information and Communication Technology, Gandhinagar (DA-IICT) since
2002. He was educated in Netarhat School(near Ranchi), IIT Kharagpur and Delhi University. He received his Ph D from University of California, Berkeley where he carried our research on “Nuclear Fusion” at Lawrence Berkeley Laboratory during 1983-86. He immediately returned to India after this and carried out research in Nuclear Fusion area at Saha Institute of Nuclear Physics, Calcutta and Institute for Plasma Research(IPR), Gandhinagar. He played a major role in India's Nuclear Fusion program and was Project Leader of the largest operational Indian Fusion Reactor, ADITYA, at Institute for Plasma Research from 1996-2002.

His current interests include applications of Wireless Sensor Network to Wildlife, Planetary Exploration (Chandrayaan mission), Nuclear Fusion, Healthcare, Agriculture etc. He has received National Science Talent Search Award, IBM Faculty Innovation Grant and HP Innovate 2009 award.

XML Structure and Content Semantic Similarity Detection
(jointly as part of ACM Distinguished Speaker series)

by Dr. Sanjay Madria, Missouri University of Science and Technology

WHERE: Class Room 2
WHEN: 3:30 - 4:30PM, August 5, 2011

Integration of XML documents demands consideration of similarities in both structure and content. This talk is about the structure and content semantic similarity detection of two XML documents from heterogeneous data sources. The talk will provide a description of the overall framework of XML integration based on content and structure semantic similarity using keys. This work introduces an approach to detect XML similarity and thus to join XML document versions using a change detection mechanism. In this approach, subtree keys still play an important role in order to avoid unnecessary subtree comparisons within multiple versions of the same document and the results improvement in the XML structure and content similarity comparisons. The main contribution is to provide an approach for evaluating semantic similarity between XML path expressions from two different XML structures. Comparisons with the previous systems shows that this approach has a better performance by a big order of magnitude in terms of detection, false-positive rates and execution time.

Sanjay Kumar Madria received his PhD in Computer Science from Indian Institute of Technology, Delhi, India in 1995. He is an Associate Professor, Department of Computer Science, at the Missouri University of Science and Technology (formerly, University of Missouri-Rolla), USA.
Earlier he was Visiting Assistant Professor in the Department of Computer Science, Purdue University, West Lafayette, USA.
