It is impractical and uneconomic to design a structure that remains elastic throughout severe ground motions. The main design philosophy is that minor structural damages are acceptable as long as the structure does not collapse. Hence, seismic base isolation of structures provides a better alternative in constructing seismic resistant structures. A fixed-base structure designed in accordance to...

The present work is an attempt to model, analyze, and control the flow at the base of an abruptly expanded circular duct by using design of experiments (DOE) and response surface methodology (RSM). Tiny-jets in the form of orifice were positioned at an interval of 900, 6.5 mm from the primary axis of the main jet of the nozzle. Experiments were conducted to measure two responses namely, base pr...

Energy reduction is one of the major problems in the design of a wireless sensor network (WSN). Multiple base stations can be used to dramatically reduce the energy consumption of sensor nodes. We consider the following problem of deploying k base stations in a wireless sensor network: Given a wireless sensor network where the location of each sensor node is known, partition the whole sensor ne...

In recent years many papers have been published for energy-efficient resource allocation in a cellular OFDMA system. In this paper we carried out combined user scheduling and power optimization based on per subcarrier or per base station for each with maximum transmits power in coordinated BS. Here three definitions of the energy efficiency are considered for system design with channel rate and...

This paper describes the results of an extensive study on the seismic behavior of a structure with damper and without damper under different earthquake acceleration frequency like Earthquake Altadena, Earthquake Lucerne and Earthquake New Hall. It is observed through nonlinear time history analysis that maximum displacement, maximum base shear and maximum acceleration can be effectively reduced...
