Issuing four instructions per cycle, this wo rksta tio n/server processor uses the Visual Instruction Set and a nonblocking memo y system to accelerate multimedia applications. Itrasparc I is a second-generation superscalar processor. It is a high-performance, highly integrated, four-issue superscalar processor based on the Sparc Version 9 64-bit RISC architecture.' We have extended the core in...

The hydrostatic extrusion is a new method of extrusion process. The most important advantage of this method is reduction of friction and close tolerance for the coating thickness. In this study, the hydrostatic extrusion simulation of bimetallic wires has performed using of finite element method. In the following the advantages of hydrostatic extrusion compared to the direct extrusion are prese...

Forging dies at high temperatures are under contact pressure, variable mechanical loads and thermal shock, furthermore they should withstand wear and friction in a high level. So, in order to increase die life, the selection of die material, coating and hardness is essential. In this review, various methods used for die life enhancement such as carbide coating, using the super alloy stellite 6 ...

In our CG model, each nucleosome, inclusive of the histone core and the ∼1.65-turn wrapped DNA, is constructed from nc = 26 charged beads, each of size σc = 2.0 nm (Fig. S1a). The beads are arranged in three stacks, where the top and bottom stacks each contain 9 beads evenly placed along a circumference of radius ro = 4.30 nm and the middle stack contains 8 beads evenly placed along a circumfer...

This study investigated the nature and causes of unsafe driving behavior at roundabouts through an on-road study. Four urban double-lane with different layouts were selected for Sixty-six drivers (41 males 25 females) aged 18–65 years took part in Unsafe behaviors observed during situ survey divided into three categories: entry behaviors, circulation exit behaviors. Three chi-square automatic i...

In the present study, the finite element analysis of the hot deep drawing process of commercially pure (CP) titanium has been performed without the blank holder in order to investigate the influence of temperature (T), die radius (Rd) and blank diameter (D) on the maximum punch force (Fp) and minimum thickness of the blank (t). Tensile tests were first conducted to extract...

Background The performance of TVS, TRS and MRI for the diagnosis of DIE have been separately reported in earlier studies. However, the three methods have not been concurrently compared in terms of their overall performance and classified results as per different anatomical locations of DIE lesions in a large study population. This study was an attempt to compare pelvic magnetic resonance imagin...
