in this paper, the consequences of well-known characteristics of near-fault ground motions, forward directivity and fling step, on the seismic response control is investigated. an integrated fuzzy rule-based control strategy for building structures incorporated with semi active friction damping system with amplifying braces (fdsab) is developed. the membership functions and fuzzy rules of fuzzy...

in the present paper, an analysis was carried out to investigate effects of radiation on a free convection flow bounded by a vertical surface embedded in a porous medium with constant suction velocity. it was under the influence of uniform magnetic field in the presence of a homogenous chemical reaction and viscous dissipation with constant heat and mass flux. the non-dimensional governing equa...

Four experiments were conducted on auditory sensitivity and discrimination of goldfish within the acoustic near field. Experiment I studied the effects of the near field on sound pressure thresholds. The sensitivity of goldfish in terms of sound pressure appeared to vary with distance from the sound source. Experiment II studied stimulus generalization and frequency discrimination within the ne...

Moment-resisting frames have extensive usage in earthquake-prone areas and high ability in energy dissipation.After the earthquake in Northridge 1994,Kobe 1995 fixed connections of steel structures have shown poor performance and generally they were caught brittle fracture of beam flange weld to the column.In order to remedy to avoid similar situations in future earthquakes,researchers introduc...

Designing and manufacturing the multiple jets simulator and experimental investigation of the multiple jets in crossflow at low velocity ratios have been studied Together with design and build a low-speed wind tunnel. A specific rake is used to determine the flow field pressure and changes in static pressure measured by pressure taps in the near field of the jets. There are generally three regi...

The effect of orientation on near-field radiative heat transfer between two complex-shaped superellipsoid particles SiO 2 is presented. under study are 50 nm in radius and variable concavity. Orientation characterized by the degree rotational symmetry two-particle systems, conductance calculated using discrete system Green's function approach to account for all electromagnetic interactions. res...
