Language and peace

This work's central thesis is that language, as historically used, has been a significant factor in creating political oppression, and economic and social discrimination. The editors argue that the challenge for the next century is to begin using language to inspire inclusion rather than exclusion.

Language and peace

This study seeks to demonstrate how critical discourse analysis can elucidate the relationship between language and peace. It provides a view on the notion of peace put forward by peace researchers, namely that peace includes not only the absence of war or physical violence, but also the absence of structural violence. Approaching the topic from various perspectives, the volume argues that language is a factor to be considered together with social and economic factors in any examination of the social conditions and institutions that prevent the achievement of a comprehensive peace. It illustrates a framework of concepts and methodologies that offer to help guide future linguistic research in this area, and also calls for foreign language, second language and peace educators to include critical linguistic education into their curricula and describes an approach for doing so.

A study of thermodynamic characteristics and predictive computer modelling of an air to water heat pump system

A study on heat pump thermodynamic characteristics has been made in the laboratory on a specially designed and instrumented air to water heat pump system. The design, using refrigerant R12, was based on the requirement to produce domestic hot water at a temperature of about 50 °C and was assembled in the laboratory. All the experimental data were fed to a microcomputer and stored on disk automatically from appropriate transducers via amplifier and 16 channel analogue to digital converters. The measurements taken were R12 pressures and temperatures, water and R12 mass flow rates, air speed, fan and compressor input powers, water and air inlet and outlet temperatures, wet and dry bulb temperatures. The time interval between the observations could be varied. The results showed, as expected, that the COP was higher at higher air inlet temperatures and at lower hot water output temperatures. The optimum air speed was found to be at a speed when the fan input power was about 4% of the condenser heat output. It was also found that the hot water can be produced at a temperature higher than the appropriate R12 condensing temperature corresponding to condensing pressure. This was achieved by condenser design to take advantage of discharge superheat and by further heating the water using heat recovery from the compressor. Of the input power to the compressor, typically about 85% was transferred to the refrigerant, 50 % by the compression work and 35% due to the heating of the refrigerant by the cylinder wall, and the remaining 15% (of the input power) was rejected to the cooling medium. The evaporator effectiveness was found to be about 75% and sensitive to the air speed. Using the data collected, a steady state computer model was developed. For given input conditions s air inlet temperature, air speed, the degree of suction superheat , water inlet and outlet temperatures; the model is capable of predicting the refrigerant cycle, compressor efficiency, evaporator effectiveness, condenser water flow rate and system Cop.

Language and identity in englishes

Key features include: • Discussion of language in relation to various aspects of identity, such as those connected with nation and region, as well as in relation to social aspects such as social class and race. • A chapter on undertaking research that will equip students with appropriate research methods for their own projects. • An analysis of language and identity within the context of written as well as spoken texts. Language and Identity in Englishes examines the core issues and debates surrounding the relationship between English, language and identity. Drawing on a range of international examples from the UK, US, China and India, Clark uses both cutting-edge fieldwork and her own original research to give a comprehensive account of the study of language and identity. With its accessible structure, international scope and the inclusion of leading research in the area, this book is ideal for any student taking modules in language and identity or sociolinguistics.

On the Error-Correcting Performance of some Binary and Ternary Linear Codes

In this work, we determine the coset weight spectra of all binary cyclic codes of lengths up to 33, ternary cyclic and negacyclic codes of lengths up to 20 and of some binary linear codes of lengths up to 33 which are distance-optimal, by using some of the algebraic properties of the codes and a computer assisted search. Having these weight spectra the monotony of the function of the undetected error probability after t-error correction P(t)ue (C,p) could be checked with any precision for a linear time. We have used a programm written in Maple to check the monotony of P(t)ue (C,p) for the investigated codes for a finite set of points of p € [0, p/(q-1)] and in this way to determine which of them are not proper.
