The sound level of air conditioning units is becoming increasingly more important to the OEM unit manufacturer and the end user of the product. Invariably, the compressor is a significant contributor to the overall sound. This paper will discuss the analysis techniques and ultimate results of redesigning a hermetic compressor housing with the goal of lowering the sound. level. The redesign proc...

Prescriptive planning models for affordable and subsidized housing policy design that have a local focus and which are intended to reflect aspects of current and/or best practices require detailed estimates of various structural parameters. These estimates should ideally reflect observations of actual housing units, households and development projects. We examine here three classes of structura...

We have constructed a new indirect ophthalmoscope. This instrument has a T-shaped housing composed of an illuminating tube and a viewing tube. A fiberoptic light source provides illumination. The inverted aerial image of the fundus coincides with the plane of the viewing window of the housing. This unit can be easily connected to a television camera for television ophthalmoscopy or to an image ...

n terms of housing issues, the primary public policy focus of economists has been the affordability of homes, mortgage availability, land-use regulation, and rent control. Studies of land-use regulation focus on the effects of regulation on the price of owner-occupied housing. Work on low-income housing has concerned itself more with issues of measurement and the debate over supply-side versus ...

This study uses a multivariate analysis to evaluate the housing and neighborhood characteristics that predict the residential choices made by non-Hispanic white, non-Hispanic black, Puerto Rican, and other Hispanic mover households in New York City from 1978 to 1987. This study evaluates minority housing choices in a multigroup context, rather than in a two-group context that implicitly assumes...

Mortgage markets are coming of age in a number of Eastern Europe and CIS countries. As they do, governments are looking to mortgage-loan associated subsidy schemes to respond to the popular demand for improved housing. This paper presents a detailed examination of the impact of two types of subsidy schemes—mortgage interest rate write-downs, both universal and income-targeted, and income-target...

Mice are used extensively in physiological research. Automated home-cage systems have been developed to study single-housed animals. Increased stress by different housing conditions might affect greatly the results when investigating metabolic responses. Urinary corticosteroid concentration is considered as a stress marker. The aim of the study was to compare the effects of different housing co...

Residential buildings are a key driver of energy consumption and also impact transportation and land-use. Energy consumption in the residential sector accounts for one-fifth of total U.S. energy consumption and energy-related CO2 emissions, with floor space a major driver of building energy demands. In this work a consistent, vintage-disaggregated, annual long-term series of U.S. housing stock ...
