This paper describes the computer aided engineering (CAE) approach to in,estigate the vibration of rolling piston type rotary compressors in the design and analysis stages. At first, the optimum design procedure for the compressor and piping system is presented. Then ,a compressor data base used for a dynamic simulation of the royary compressors are carried out. Finally, a practical application...

In male vertebrates the display of courtship behavior depends on the presence of testicular androgens. However, social experiences in adulthood can alter the hormonal dependence of courtship behavior in a variety of species, and we have previously proposed that these behavioral changes are linked to changes in neural metabolic capacity (cytochrome oxidase activity). Here we investigated the eff...

A team of specialist advisors, the authors of this paper, provided design advice to the architects and engineers of the EC Thermie target projects SUNH (Solar Urban Hew Housing) and SHINE (refurbished housing) during the design phase, which is still ongoing. M. Wilson is the co-ordinator of this task of advisors dealing with the ‘Specific Innovative Technologies’ (SIT) of: Daylighting (M. Wilso...

We study sources and consequences of uctuations in the U.S. housing market. Slow technological progress in the housing sector explains the upward trend in real housing prices of the last 40 years. Over the business cycle, housing demand and housing technology shocks explain one-quarter each of the volatility of housing investment and housing prices. Monetary factors explain less than 20 percent...

This paper explores the role of social impact assessment (SIA) as a tool to evaluate sustainability council estate redevelopment or regeneration. The first revises evolution concept SIA in recent years, arguing that it should be included core part planning approval process enhance community-centred decision-making practices, claimed by Just Space network London. To contribute this argument, how...

Symbioses include some of the clearest cases of coevolution, but their origin, loss or reassembly with different partners can rarely be inferred. Here we use ant/plant symbioses involving three plant clades to investigate the evolution of symbioses. We generated phylogenies for the big-eyed arboreal ants (Pseudomyrmecinae), including 72% of their 286 species, as well as for five of their plant ...

â housing as the smallest element of the habitats is one of the most important urban usage and one of the major development indices of a country. the purpose of this paper is investigation of housing situation of income groups and estimation of low income groups housing using statistical techniques in housing programming. this paper attempts to investigate the housing situation of income group ...
