An analytical design procedure to determine optimal noise hazard control strategies for industrial facilities is presented. Its objective is to determine a set of appropriate noise controls to eliminate or reduce noise levels so that workers' daily noise exposure does not exceed a permissible level. From a given noise control budget, engineering controls will be firstly implemented, followed by...

In this paper, a stochastic model [5] for the turbulent fiber laydown in the industrial production of nonwoven materials is extended by including a moving conveyor belt. In the hydrodynamic limit corresponding to large noise values, the transient and stationary joint probability distributions are determined using the method of multiple scales and the Chapman-Enskog method. Moreover, exponential...

Industrial computed tomography (CT) images often suffer from beam hardening (BH) artefacts. Since beam hardening correction (BHC) is crucial in industrial CT, it is worth acquiring a good understanding of the BHC algorithms. The purpose of this work concerns the development of a phantom-based framework to assess the performance of BHC algorithms in industrial CT, and its application on several ...

background: noise is one of the most important hazardous physical factors in industrial environments. this study aimed to determine the effects of noise exposure on serum cortisol level and some blood parameters among male workers of a steel production company. methods: this cross-sectional study was conducted on 50 male workers in a steel production company. in order to assess the changes in b...

background: noise pollution is one of the most harmful ambiance disturbances. it may cause many deficits in ability and activity of persons in the urban and industrial areas. it also may cause many kinds of psychopathies. therefore, it is very important to measure the risk of this pollution in different area. methods: this study was conducted in the department of medical physics and biomedical ...

background: noise is one of the most pervasive hazards in industrial settings. this retrospective study was carried out to assess the effects of noise exposure on hearing status, blood lipids and blood pressure of employees of a local fireclay mine. methods: two hundred and forty male workers were studied. data on audiometric measurements, blood lipids and blood pressure were derived from the w...

Because of their good support and easy deployment, wireless ad-hoc networks are currently widely being used for many industrial or military applications. Like other communication networks, environmental conditions can have considerable impact on the performance of wireless ad-hoc networks. Temperature is a good example which results in thermal agitation of the charge carriers. Consequently, we ...

Guidelines and regulations for the siting of industrial wind turbines (IWT) close to human habitation are generally predicated on the need to protect the sleep of the residents. ssumptions that IWT noise can be regarded as similar to other forms of environmental noise (traffic, rail and aircraft) and is masked by ambient noise. There has been no independent verification that these assumptions a...

The acoustic sound level caused as secondary effects of industrial energy conversion processes is often perceived as an unwelcome noise emitted into the enclosing surrounding. In order to verify design aspects for reducing such undesirable noise emission in particular within variable electric speed drive applications, suggested novel combinations of electrical and mechanical motor topologies ar...
