background and aims: since using city power for welding process is not allowed, diesel generators are used as a power supply in construction industries. they could be introduced as a main source of noise pollution. the purposes of this study were to assess and control noise pollution produced by construction diesel generators in hamadan, iran. methods: in this descriptive, cross-sectional study...

With the development of automobile industry, automobile glass type and quantity increased quickly. Automobile glass not only protects the passenger, but also affects the security, appearance of automobile and passenger’s comfort. As a result, optical performance of automobile glass, which is the most parameter, has provoked the attention of manufacturer and consumer. At present, the detection t...

Today, planning and control of logistic processes on automobile terminals are generally executed by centralised logistics systems, which cannot cope with high requirements for flexible order processing due to increasing dynamics and complexity. The main business processes on automobile terminals – notification of vehicles by automobile manufacturer, transport to automobile terminal, storage and...

Results of an epidemiology study of populations living near a freeway and in the high desert area of Southern California for levels of platinum, palladium and lead are presented. Three age groups (children, young adults, and mature adults) were sampled twice for blood, urine, hair, and feces. Air, water, and soil samples were collected in the areas of the residences of the two populations. The ...

This research introduces the scale of innovation intensity (SIIN) based on meta-taxonomy that subsumes other, less comprehensive taxonomies. The SIIN is similar to seismic scale used to measure the intensity of earthquakes. The intensity of technological change is measured by an indicator, called Magnitude, based on the impact of technological innovations on the economic system. The theory is a...

The present study was conducted with the aim of designing after sales service curriculum pattern of automobile industry in Iran. Methodology: This was a mixed exploratory study (qualitative and quantitative). The research population in both qualitative and quantitative pa...

This paper presents a multibaseline stereo technique specially suited to detecting obstacles. First, we describe traditional multibaseline stereo and explain why it is not suitable for obstacle detection. This analysis leads directly to a suitable method. Then we describe the obstacle detection system that we have built. Finally, we show results from our system for a variety of different obstac...

Highway pavement are deteriorating fast due to lack of timely maintenance, leading to higher vehicle operating costs, increasing number of accidents etc. Thus, timely maintenance of the highway pavement is essential. Because, once pavements start to deteriorate; they deteriorate rapidly beyond the point where maintenance is effective. Thus, there is an urgent need to develop a strategy for main...
