Signal Processor for Millimetric Wave Radar Seeker for Antitank Guided Missile

The missile borne signal processor for the millimetric wave active radar seeker of the third generation type antitank guided missile (ATGM) system with lock-on-before-launch capability is discussed. The range and angle tracking systems are described and the results are presented. Feasible improvements in signal processor using coherent-on-receive scheme for achieving higher ranges, have been identified and are being implemented

Concepts And Measures of Outreach and Sustainability in Microfinance Institutions: A comprehensive literature review

The terms outreach and sustainability are used in many fields of study. The terms are among the most commonly raised concepts in microfinance literature as well. The purpose of this article is therefore, to introduce the terms and their application to the academic community of the finance discipline. The article emphasizes the concepts, the measures and existing schools of taught with regard to outreach and sustainability in microfinance institutions. Keywords: Outreach, sustainability, concept, measures, and school of taugh

Simulation of mirror inversion of quantum states in an XY spin chain using NMR

We report an experimental quantum simulation of unitary dynamics of an XY spin chain with pre-engineered couplings. Using this simulation, we demonstrate the mirror inversion of quantum states, proposed by Albanese et al. [Phys. Rev. Lett. 93, 230502 (2004)]. The experiment is performed with a 5-qubit dipolar coupled spin system using nuclear magnetic resonance techniques. To perform quantum simulation we make use of the recently proposed unitary operator decomposition algorithm of Ajoy et al. [Phys. Rev. A 85, 030303 (2012)] along with numerical pulse optimization techniques. Further, using mirror inversion, we demonstrate that entangled states can be transferred from one end of the chain to the other end. The simulations are implemented with high experimental fidelity, which implies that these kind of simulations may be possible in larger systems.Comment: 9 pages, 6 figure

On the morphology of Bostrychia tenella (Vahl) J. Agardh

Boergesen (1937) reported Bostrychia tenella (Va hI.) J. Ag. from Indian waters. Some details regarding the morphology of the alga are available to some extent by the works of Montagne(1828).Falken\>"rg (1901). Post (1936). Tseng(1942)and Joly (1954) . The detailed structure of the alga and the development of the reproductive structures are not known completely. Advantage was taken of the occurrence of Bostrychia tenella in the Gulf of Mannar at Mandapam to study the morphology of the species both from living specimans and from material fixed in 4% formalin and forma lin -acatic-alcohol. Suitable preparations were stained in eosine and mounted in glycerine for microscopic examination. Sometimes the material had to be softened by placing in 1 % acetic acid or 1 % lithium chloride solution. While thin sections were used frequantly. most datails could be observed on whole mounts and squashes of suitable pieces of the thallus of the alga

Development of a creep data base management system for engineering materials

A fully menu driven creep data base management system has been developed for various high temperature materials using the client /server (C/S) architecture with Sybase system. 10 as backend and power builder 4.0 as an inter-face. The relational data base constitutes of various classes of materials, their heat treatment, prior history and the related creep properties at different test condit-ions, in addition to the source process route and chemical composition details.Top-down approach has been adopted in designing the entity-relationship (E-R) model. The creep data is organized into the third normal form, and the entire system is divided into manageable modules. Coding for the system is done using Transact-SQL for data defin- ition, manipulation and control operations, and power script language for application development. This article briefly outlines the formulation of data base design, and the implemented E-R model, in addition , to the prese-ntation of various screen formats used for data entry and retrieval modules

Study of Variation in Upper Air Density Over India

The paper presents the seasonal variations and distribution of atmospheric density in the upper air over Indian region. The study reveals the density gradient has a down slope from North to South during winter and South to North, upto 200 mb level in summer. At 850 mb level the isopyenic lines forms a shallow through over East coast and at 700 mb level Bombay-Poona region while over the rest of the country the isopyenics show no special features. At 500 mb level three is a well marked trough of density over North Western India. Above 200 mb level an altogether different picture throughout the year is noticed

Love Wave Propagation in Poro elasticity

It is observed that on similar reasons as in classical theory of elasticity, SH wave propagation in a semi infinite poroelastic body is not possible and is possible when there is a layer of another poro elastic medium over it i.e., Love waves. Two particular cases are considered in one of which phase velocity can be determined for a given wave length. In the same case, equation for phase velocity is of the same form as that of the classical theory of Elasticity
