So far, there have been three major technological advances. The first industrial revolution in Britain began and hydraulic and steam machines were introduced to factories. The Second Industrial Revolution differentiated between components and assembly of products based on the division of labor. This led people to the era of cost-effective products and mass production. The Third Industrial Revol...
in practical situations, distribution network loads are the mixtures of residential, industrial, and commercial types. this paper presents a hybrid optimization algorithm for the optimal placement of shunt capacitor banks in radial distribution networks in the presence of different voltage-dependent load models. the algorithm is based on the combination of genetic algorithm (ga) and binary part...
for the past 3 decades, creating industrial clusters have been considered as an approach for the development of most small and medium enterprises. the goal of this programme is that all small and medium enterprises locating in a certain geoghraphic area can concentrate on cluster approach to collaborate in market research, production design, training and other activities that are not economical...
today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...
Solid waste is the unwanted or useless solid materials generated from combined residential, industrial and commercial activities in a given area. It may be categorised according to its origin (domestic, industrial, commercial, construction or institutional); according to its contents (organic material, glass, metal, plastic paper etc); or according to hazard potential (toxic, non-toxin, flammab...
in order to investigate the prevalence of infection with bovine viral diarrhoea virus(bvdv) of cattle in ahvaz,blood samples were collected from jugular vein of 572 cattle(521 female, 51 male) from industrial and nonindustrial farms. sera were stored at -20?c while waiting for analysis. the sera were tested by elisa, using a commercial elisa kit for detection of specific antibody to bovine vira...
A strategy to improve the performance of current commercial industrial robots is presented in this paper. This strategy involves cooperation of two robotic manipulators: the robotic controlled impedance device (RCID) and a commercial industrial robot. The RCID is a small six degrees-of-freedom (DOF) high bandwidth force–impedance controlled parallel manipulator, developed at the School of Engin...
