Steel Plate Shear Wall (SPSW) is an emerging seismic load-resistant system that, compared to other systems, enjoys the advantages of stable ductile behavior, fewer detailing requirements, rapid constructability, and economy. American seismic provisions decree that a SPSW should be designed as a moment frame with a web infill plate. Specifically, in case of buildings taller than 160 ft, it decre...

Regarding to rapidly changing and highly competitive business environment it will become increasingly important for organizations to measure their performances appropriately. With respect to special characteristics of pharmaceutical industry and lack of reported performance measurement, this study tries to design an integrated performance measurement model for pharmaceutical companies. For gene...

Paper proposes a new design and a simulation model for the pico base station based on IEEE 802.16e standard and evaluates its performance in a mutihop-relay and mesh networks. The proposed base station design allows multihoprelay communications and thus opens a possibility for the proposed base station to be an element of mesh networks. The conventional IEEE 802.16e base stations interconnected...

in this paper, we study wsn design, as a multi-objective optimization problem using ga technique. we study the effects of ga parameters including population size, selection and crossover method and mutation probability on the design. choosing suitable parameters is a trade-off between different network criteria and characteristics. type of deployment, effect of network size, radio communication...

the design and application of a fuzzy logic based controller to a leakage current relay waspresented in this paper. a novel approach based on fuzzy logic to form the tripping action of leakagecurrent relay was investigated. in addition to the theoretical aspect of fuzzy logic, detection of a leakagecurrent, measurement of the leakage current, determination of its duration, trip opening of fault...

earlier studies have shown conclusively that a tuned liquid damper (tld) is effective for controlling vibrations in structures subjected to narrow-banded wind excitations. a recent numerical study has shown that if the design parameters of a tld are properly set, this device could also be very effective for controlling structural vibration to broad-banded earthquake excitations. here the result...
