Investigation of Offences against National Security

The study is a close scrutiny of the process of investigation of offences in India along with an analysis of powers and functions of the investigating agency. The offences, which are prejudicial to sovereignty, integrity and security of the nation or to its friendly relations with foreign states, are generally called the offences against national security. Offences against national security being prejudicial to the very existence of the nation and its legal system, is a heinous and terrible one. As early as 1971 the Law Commission of India had pointed out the need of treating the offences relating to national security and their perpetrators on a totally different procedural footing. The recommendation that, all the offences coming under the said category ought to be brought under the purview of a single enactment so as to confront such offences effectively. The discrepancies in and inadequacies of the criminal justice system in India as much as they are related to the investigations of the offences against national security are examined and the reforms are also suggested. The quality of criminal justice is closely linked with the caliber of the prosecution system and many of the acquittals in courts can be ascribed not only to poor investigations but also to poor quality of prosecution.

AN INVESTIGATION ON AIR-SEA INTERACTION IN THE INDIAN OCEAN DURING CONTRASTING MONSOONS

The study is undertaken with an objective to investigate the linkage between air-sea fluxes in the Indian Ocean and monsoon forcing. Since the monsoon activity is linked to fluxes, the variability of surface marine meteorological fields under the variable monsoon conditions is also studied. The very objective of the present study is to document various sea surface parameters of the Indian Ocean and to examine the anomalies found in them. Hence it is attempted to relate the anomaly to the variability of monsoon over India, highlighting the occasion of contrasting monsoon periods. The analysis of anomalies of surface meteorological fields such as SST, wind speed and direction, sea level pressure and cloud cover for contrasting monsoons are also studied. During good monsoon years, the pressure anomalies are negative indicating a fall in SLP during pre-monsoon and monsoon months. The interaction of the marine atmosphere with tropical Indian Ocean and its influence on ISMR continue to be an area of active research.

An Experimental Investigation of the Effect of Flange Angle on Radiation Patterns of V-Slot Waveguide Antenna

Results of exhaustive study of the effect of metallic flanges on H-plane radiation characteristics of V-slot waveguide antenna are presented . It has been established that the beam can be sharpened or broadened by varying the flange angle . The adjustment of the flange angle and flange width would further improve the radiation pattern , yielding optimum efficiency from the flanged system
