Comparison of the dynamic behavior

چکیده
| The Inverse Discrete Cosine Transform (idct) is used in almost all video-decoders, like mpeg and hdtv. In de process of video decoding, the idct is a computationally heavy part. One of the performance characteristics is the power consumption , which is related to the dynamic behavior of the hardware. In this paper the signal transitions that occur in the multipliers are analyzed with vhdl, when two's complement arithmetic is changed in signed binary arithmetic. The simulations show that the signed binary multipliers need about three time less signal transitions than two's complement multipliers.

Comparison of Seismic Behavior of Buckling-restrained Braces and Yielding Brace System in Irregular and Regular Steel Frames under Mainshock and Mainshock-Aftershock
Due to low stiffness of braces after yielding, the structures with buckling-restrained braces (BRBs) experience high residual drifts during an earthquake, which can be intensified by aftershocks and causes considerable damages to structures. Also, due to poor distribution of stiffness, this problem is exacerbated for irregular structures. Recently, the yielding brace system (YBS) has been intro...

متن کاملComparison of Geotextile Layers Effects on Static and Dynamic behavior of Pavement
One of the methods for the improvement of soil against the tensile stresses is using the artificial supplements in soil such as metal belts or nets, polymer materials and natural fibers. Technically this method is called the reinforced of soil. When a pavement is located on soft soil, great deformations can occur as a result of the crossing of traffic load in superstructure layers of the body....
متن کاملPull-in behavior analysis of vibrating functionally graded micro-cantilevers under suddenly DC voltage
The present research attempts to explain dynamic pull-in instability of functionally graded micro-cantilevers actuated by step DC voltage while the fringing-field effect is taken into account in the vibrational equation of motion. By employing modern asymptotic approach namely Homotopy Perturbation Method with an auxiliary term, high-order frequency-amplitude relation is obtained, then the infl...
متن کاملEffects of the asymmetric behavior of the shape memory alloy on nonlinear dynamic responses of thick sandwich plates with embedded SMA wires
In the present article, the dynamic behavior of sandwich plates with embedded shape memory alloy (SMA) wires is evaluated for two cases wherein (i) the stress-strain curve of the superelastic behavior of the SMA wires is symmetric and (ii) the mentioned curve is non-symmetric. A modified version of Brinson’s constitutive model is proposed and used. The high non-linearity in the behavior stems f...
