this research was performed to determine the efficiency effect of sedimentary environment of kerman city area on soil structure bycomparing natural and reconstituted consolidation curves. in this regard, four different criteria such as sensitivity strength, stresssensitivity, schmertman criteria and the result of the uniaxial compression test were used. the base of these criteria is to compare ...

Lossy image compression is used in many applications including remote sensing. Image size and number increase this often leads to the necessity apply compression. In lossy compression, it assumed that rate-distortion curves are monotonous functions assumption put into basis of control. However, has been shown recently there grayscale color images called “strange” for which not monotonous. paper...

The use of an alphabet of line segments to compose a curve is a possible approach for curve data compression. Curves having more sophisticated topology with self-intersections can be handled by methods considering recursive decomposition of the canvas containing the curve. We propose a graph theory based algorithm for tracing the curve directly to eliminate the decomposition needs. This approac...

The properties of hot dense helium at megabar pressures are studied with two first principles computer simulation techniques: path integral Monte Carlo simulation and density functional molecular dynamics. The simulations predict that the compressibility of helium is substantially increased by electronic excitations that are present in the hot fluid at thermodynamic equilibrium. A maximum compr...

Compression-compression fatigue testing of metallic-glass foam is performed. A stress-life curve is constructed, which reveals an endurance limit at a fatigue ratio of about 0.1. The origin of fatigue resistance of this foam is identified to be the tendency of intracellular struts to undergo elastic and reversible buckling, while the fatigue process is understood to advance by anelastic strut b...

In this paper, we study the scalability of an atmospheric modeling application on a cluster with commercially available off-the-shelf interconnects. It is found that interconnects with large latency and low bandwidth are major bottlenecks for performance scalability. Response curves for latency shows that for large message sizes latency is extremely sensitive to the size of the message. Thus, d...

Measurement of stress-strain curves under tension-compression reverse loadings is crucially important for the understanding Bauschinger effect aluminum alloy sheets. Uniaxial compression sheet metals carried out with supporting flat plates, which clamp a specimen to prevent it from buckling. The forces generate thickness stress and friction forces. In present study, influence force on curve val...

percutaneous vertebroplasty is a promising therapeutic technique for pain control in patients with pathologic fractures of vertebral bodies. percutaneous vertebroplasty is an appropriate treatment for vertebral pathologic fractures, which is resistant to other usual treatment. it is a useful and only choice in special cases, because of less tissue damage and there is no risk of open surgery and...

processing map for hot working of ti-if steel has been developed in the temperature range of 750 to 1100 °cand strain rate of 0.01 to 100 s-1. this map in the austenite region exhibits a single domain with a peak efficiencyof 45% occurring at 1025 °c and strain rate of 0.02 s-1. the domain extends over the temperature range of 1000to 1100 °c and strain rate range of 0.01 to 1 s-1. the true stre...
