by application of design spectra in seismic analyses, determination of design spectra for different site conditions, magnitudes, safety levels and damping ratios will improve the accuracy of seismic analysis results. the result of this research provides different design acceleration spectra based on iran earthquakes database for different conditions. for this purpose first a set of 146 records ...

The purpose of the investigation was to derive the optimal configuration of the spectrum analyser when used for the exposure assessment around base stations, together with the associated uncertainty and the underlying rationale for the chosen settings. A base-band simulation model for both the spectrum analyser and the Universal Mobile Telecommunications System (UMTS) communication signals has ...

Recorded ground motions in near fault region have completely distinct nature from others that recorded in far field of the fault. Near source outcomes cause much of the seismic energy to appear in a single large and long period pulse at the beginning of the velocity record. Assaluyeh complex is located near the reverse Assaluyeh fault that is a segment of Mountain Front Fault. This complex cont...

An LSI is fabricated and measured to demonstrate the feasibility of the VDD-hopping scheme in a system level. In the scheme, supply voltage, VDD, is dynamically controlled through software depending on workload. The VDD-hopping scheme is shown to reduce the power to less than 1/4 compared with the conventional fixed-VDD scheme. The power saving is achieved without degrading the real-time featur...

A b s t r a c t m As many biomechanists indicate~ tendon plays important role for running or jumping motion. It stores the kinetic energy as a potential energy during stance and also absorbs the impulse at touch down. Inspired by such biomechanical studies~ we propose a new simple mechanical model for hindlimb of a dog to realize a robot that imitates dog running~ and the hardware design of one...

We solve the design spectrum problem for all theta graphs with 10, 11, 12, 13, 14 and 15 edges.
