PREFACE

As is well known, research is an integral and an important part of any higher education process. Research activities being undertaken at the universities give the universities the status of being repository of knowledge. We at BITS, Pilani fully understand and appreciate the importance of research and accordingly we work most sincerely towards promoting basic and applied research activities. In addition to basic research activities, which are the back-bone of any applied/industrial research, we carry out applied and directed research also to sustain the research activities.

University research is usually economical too as compared to its counterpart i.e. researches being done at industrial set-up because for researches being done at universities, manpower in the form of very bright and creative students is always available. They undertake research projects as a part of their education process itself. Besides students, every teacher also has to conduct research as an integral part of his/her duties because teachers are expected not only to assimilate and disseminates the knowledge but also to generate new knowledge, which is possible only through research.

The number of students in higher degree institutions is increasing every year. There used to be about 7 million students in the institutions of higher learning a decade ago and this number has now grown to about 13.5 million students. This reflects the enormity of research pool available and we have to consciously utilize this energetic and creative pool of research students by providing them with proper guidance and directions for rapid economic growth of the country through research.

We at BITS believe in the philosophy that if the research fructifies into a commercially viable product or process, we must go for patenting the same which in due course would generate funds for further research through royalties obtained from these intellectual properties/patents. However if the research work is unlikely to generate sufficient economic input (such as for research related to certain basic sciences where commercial interest may not lie), it would be better to opt for publishing results rather than going for IPR/patents. Also, if we go for patenting, after filing the patent applications, publications are to be encouraged in the larger interest of scientific community/research. After all, the universities are the main forum for seeding and breeding of research ideas and we want to sustain this aspect. Also, through collaboration with industrial partners, we intend to go for and strengthen the process of scaling up of the research for commercialization of our intellectual properties and train our researchers in the delivery aspects of corporate research. Right now most of the research projects do not strictly follow a time line and such a practice may not be conducive for corporate research or even acceptable to the corporate world. Society also has to finally get benefited by the researches being done at the top class institutions such as BITS, Pilani and this could either be in form of a product or a process or policy or extension activity for socio-economic upliftment of every one in the society.

‘Research at BITS’ is an annual document that brings out the programme of Research, Consultancy and Publication work undertaken by BITS Pilani.

I. INTRODUCTION

Preamble

Research at BITS is a component of an integrated activity encompassing teaching as well as its linkages with the outside world of Academia and Industry. A large number of students at all levels in the three-tier structure of the educational programmes are involved in research. At the first-degree level, a one-semester full-time thesis-seminar course and at the higher degree level a dissertation course offer excellent opportunities to bright students to be involved in research. In the doctoral programme, a large number of Ph.D. students located on-campus, off-campus or at outside centres, are engaged in research work in various research areas. The Institute's linkages with industries, R&D Centres and other institutions in the country and abroad have given a further thrust to the research activities of the Institute.

Promotional Efforts for Research at Doctoral Level

Faculty Development Scheme
