With the evolving needs of today’s manufacturing industries in the area of product development, 3D CAD model has become very important. Often in many situations there is a need to remanufacture a physical part where the CAD data is not available with the manufacturer or is lost because of several reasons. In such cases reverse engineering is found to be an effective and efficient tool. Reverse ...

We analyze a general market for an industry of competing service facilities. Firms differentiate themselves by their price levels and the waiting time their customers experience, as well as different attributes not determined directly through competition. Our model therefore assumes that the expected demand experienced by a given firm may depend on all of the industry’s price levels as well as ...

background : noise pollution is one of the important issues of pollutant in workplaces and is almost one of the harmful agents for workers. at present, instrumental based inspections for determining the index levels of noise in workshops is performed. this method is requiring a time consuming and ex-pensive in large scale inspection for workplaces. classification of workplaces based on noise po...

noise is defined as unwanted or objectionable sound. human susceptibility to noise varies in terms of intensity, altitude, timbre of sound, personal sensibility, age, and history of ear disorder. noise pollution which is the result of heterogeneous and uncontrolled developments of cities is one the serious problems in large cities of iran. although noise pollution in kerman (located in southeas...

acoustic experimental data of irib (islamic republic of iran broadcasting) server room was taken to measure the acoustic noise characteristics of frequency and sound pressure level (spl). the purposes of this paper are measuring the noise pollution and its evaluation through the regulations. the measurements were taken in two stages. the first one was taken at 10 points by sound investigator 22...

background; noise mapping in industry can be useful to assess the risks of harmful noise, or to monitor noise in machine rooms. using gis -based software for plot of noise maps in an indoor noisy work environment can be helpful for occupational hygienists to monitor noise pollution. methods; this study was carried out in noisy packaging unit of a food industry in ghazvin industrial zone, to eva...

large urban areas are facing growing problems of noise pollutions. geospatial information systems (gis) can conveniently be adapted to gather, analyze and present noise information. gis can also be extended to answer to user specific problems through deterministic and statistics models. the objectives of this research were to measure urban traffic noise levels, analyze temporal and spatial dyna...

introduction: among the environmental pollutions, noise is very important for its physiological  and psychological effects on human. traffic noise is one of the most important pollutants and the  hospitals  are  one  of  the  critical  places  regarding  this  type  of  noise.  for  these  reasons,  in  the  summer  of  1382,  the  traffic  noise  of  mashhad  main  streets  around  the  hospit...
