distributed generation (dg) sources are becoming more prominent indistribution systems due to the incremental demands for electrical energy. locationsand capacities of dg sources have great impacts on the system losses in adistribution network. this paper presents a study aimed for optimally determiningthe size and location of distributed generation units in distribution systems withdifferent l...

Abstract The movement of the floating connecting mechanism between a hydraulic support and scraper conveyor is space movement; thus, when pushes conveyor, there an error actual distance theoretical moving distance. As result, cannot obtain straightness requirement. Therefore, law analyzed programmed into Unity3D to realize accurate pushing via support. Coal Seam + Equipment Joint Virtual Straig...

in the present study, some biological aspects of capoeta trutta (heckel, 1843) have been examined for the aim of future stock assessment, exploitation and conservational managements. a total of 103 fish specimens were collected seasonally from seymareh river, tigris basin, iran, in four seasons during 2011-2012. observed maximum age was 4 + in both sexes and sex ratio obtained as 1m:1.9f. analy...

In low-latitude areas less than 10° in latitude angle, the solar radiation that goes into still increases as cover slope approaches angle. However, amount of water is condensed and then falls toward solar-still basin also increased this case. Consequently, yield significantly decreased, accuracy prediction method affected. This reduction inversely proportional to time which stays on inner side ...

Bush-crickets (Orthoptera: Tettigoniidae) generate sound using tegminal stridulation. Signalling effectiveness is affected by the widely varying acoustic parameters of temporal pattern, frequency and spectral purity (tonality). During stridulation, frequency multiplication occurs as a scraper on one wing scrapes across a file of sclerotized teeth on the other. The frequency with which these too...
