1. | Title | Security and Management of Computer Networks |
Sponsor | DRDO | |
Period | 22 March 1993 to 22 May 1998 | |
Principal Investigato | Dr. A.K. Sarje | |
Brief Description | The aim of the project is to develop methods securing computer networks from passive and active attacks and to develop aids for network manager in monitoring and diagnostics of the secure networks. The development of security mechanisms for Computer Networks have not progressed at the same rate as the communication technology. Security mechanisms hinder communication and limit interconnectivity. Today, many networks are in place that cannot be used securely. A mechanism with emphasis on privacy and security is to be developed for computer networks. |
2. | Title | Generating Hindi from LTAG output for English text |
Sponsor | AICTE | |
Period | April 1996 to March 1999 | |
Principal Investigato | Prof. (Mrs) Kumkum Garg | |
Brief Description |
The technique to be used to design the MT package would be based on an AI approach, integrating the purely declarative Lexicon with the purely procedural parser/geenrator, into a resultant MT software that would be totally general and extensible to any bi-lingual translation. |
3. | Title | Object Oriented Implementation of Real Time Database Management Systems |
Sponsor | Defence Research and Development Organization, New Delhi | |
Period | Three years | |
Principal Investigato | Dr. R.C. Joshi | |
Brief Description | The Real Time Database Systems are extensively used in autopilot systems, automated factories with robots, war game simulation systems, etc. The objectives of the project include design of kernel suitable for Real Time Database applications with special emphasis on development of query language and its optimization, transaction processing techniques, concurrency control, buffer management and disk I/O scheduling. |
4. | Title | Generation of Efficient Computer Codes for the Estimation of RCS of Complex Bodies |
Sponsor | Department of Electronics, Govt. of India | |
Period | 4 years | |
Principal Investigato | Dr. (Mrs) Bharoti Sinha | |
Brief Description | The project aims for preparing softwares using numerical methods to estimate the energy scattered by any complex object. Since the scattered energy completely characterizes the object, its estimation is useful in many military and civilian applications. The numercial methods used to solve Maxwell's equations include Method of Moments, GO, PO & GTD. Newly developed "Shooting and Bouncing Ray" technique using NURBS surfaces is also being used to estimate RCS. |
5 | Title | Cavity-Backed Microstrip Patch Antennas |
Sponsor | University Grants Commission | |
Period | Dec 1997 to Dec 2000 | |
Principal Investigato | Dr. S.N. Sinha | |
Brief Description | The principal drawback of microstrip
antennas is their narrow impedence bandwidth which results from the small
seperation between the patch and the ground plane. The most simple way
to improve the bandwidth is to increase the thickness of the substrate.
However, this results in the generation of surface waves which cause a
reduction in radiation efficiency and scan blindness in an array.
Surface wave modes can be suppressed by enclosing the patch antenna within metal walls. In this project, therefore, detailed investigations are being carried out on the effect of cavity backing on the performance of microstrip patch antennas. The main objectives are:
