The paper presents the development of a system which will help wirelessly monitor the health parameters of a soldier and also send and receive messages wirelessly from the base station computer. The system must also detect reduced vitals and alert the base station along with the GPS location so that a rescue team can be sent. The system comprises of a biosensor signal conditioning module, a GPS module, a keypad and a LCD. These are interfaced with the Stellaris LM4F120XL Launchpad, which in turn broadcasts messages wirelessly via the EZ430-RF2500 wireless module. These messages are sent to all the EZ430-RF2500 modules in the locality. A LabVIEW program has been developed to act as the central commanding station. This will process all the data from the individual soldiers, display the data and perform the functions mentioned. This will help in strategic planning of military missions and also to reduce casualties.

The experimental determination of the coefficient of hydraulic resistance of a perforated plate with a layer of balls adjoining to it Yu V Smorchkova, A N Varava, A V Dedov et al. Abstract. The shock/blast waves generated due to explosions cause wide spread damage to the objects in its path. Different techniques have been used to attenuate shock wave over pressure, to reduce the catastrophic effects. Perforated plates can be used effectively to attenuate the shock wave pressure. In this paper shock wave interaction with perforated plates is simulated using COMSOL multiphysics software. The pressure drop varied from 43.75% to 26% for porosity varying from 10% to 40.
