| Summary/Abstract |
An intelligent semi-active anti-vibration mount using a magnetorheological (MR) fluid is designed and developed for onboard applications. The mount consists of a load bearing elastomer, MR fluid chamber; MEMS based vibration sensor and a controller for closed loop feedback mechanism. The controller regulates the solenoid current in the MR fluid chamber, which in turn regulates the flow of MR fluid through the valve. Comparison of the performance of MR mount with a passive resilient rubber mount shows that the former provides 7 dB extra damping at resonance compared to the later and the isolation of MR mount starts at 10 Hz compared to 50 Hz by rubber mount. This mount can operate in real time, passive and active modes by using a closed loop feedback control mechanism. The efficacy of the mount for outdoor applications is evaluated by characterizing the mechanical, environmental, electrical and electromagnetic properties as per MIL-17185, JSS-55555 and IEC 61000 standards and found to be superior compared to passive mounts. The mount is being evaluated for onboard applications in INS Ranvijay.

| Summary/Abstract |
Strengthened Indo-US proximity has become a notable factor in the regional security architecture of the Indo-Pacific region, and also it raises ongoing concerns about its robustness. This article analyses the geostrategic, geoeconomic, security-related and defence-connected Indo-US relations in the region over the last two decades, highlighting the growing multidimensional convergence of US and Indian interests in the Indo-Pacific regional security architecture. In the final part, this article also sketches the future implications of Indo-US proximity and seeks to identify potential risks.

| Summary/Abstract |
A far-sighted food policy is essential to facilitate efficient functioning of food production and management systems, especially for a country like India where household level food security still remains elusive. In this context, reliable mechanisms for generating outlooks on key variables such as demand, supply, trade, prices, etc., of important food commodities forms an essential basis for planning. This paper explores the theoretical underpinnings as well as practical applications of the Cereal Outlook Model, a dynamic, partial-equilibrium model, developed by the authors with the specific purpose of generating future outlooks on major cereals in India. Based on this, projections as well as policy simulations on main demand and supply side variables of rice, wheat and maize were carried out for the period spanning 2011-2025. The model results indicate fast-growing trends in demand and supply of the three cereals considered. Though growth in demand would be sufficiently high due to growing per capita income, population and urbanisation; supply would keep pace owing to the emergence of new areas contributing towards incremental production. Consequently, the net trade of all three commodities would remain positive, though some signs of tapering off in net trade are expected in case of wheat and maize.
