Support for video transmission is rapidly becoming a common requirement. Video coding schemes such as H.26L are combined with multilayer multicast protocols such as SPLIT to improve the quality of video received at the receiver. In this paper, we built a simulation system using a modified version of JVT (Joint Video Team) encoding / decoding software package and Network Simulator NS-2, to evalu...

PURPOSE To analyze the effectiveness of anterior pelvic plating and subsequent percutaneous sacroiliac joint screw fixation in patients with unstable pelvic ring injuries. MATERIALS AND METHODS Thirty-two patients were included with twenty-one males and eleven females. The mean age was 41 years (range, 19-76). The mean follow-up period was 51 months (range, 36-73). According to AO-OTA classif...

Muscles behave as elastic springs during the initial strain phase, indicated as short range stiffness (SRS). Beyond a certain amount of strain the muscle demonstrates a more viscous behavior. The strain at which the muscle transits from elastic- to viscous-like behavior is called the elastic limit and is believed to be the result of breakage of cross-bridges between the contractile filaments. T...

This article presents the results of research into causes wear piston pin mounted in bosses by means a hinge joint and connecting rod small end thermocompression bond. Changes geometry pin-top surface structure, which are caused mutual influence mating surfaces variable lubrication conditions, presented. The progress scuffing as result insufficient elements or oil film breaking is demonstrated....

For many years, studies of chromosome evolution were dominated by the random breakage theory, which implies that there are no rearrangement hot spots in the human genome. In 2003, Pevzner and Tesler argued against the random breakage model and proposed an alternative "fragile breakage" model of chromosome evolution. In 2004, Sankoff and Trinh argued against the fragile breakage model and raised...

Understanding fluctuation-induced breakages in polymers has important implications for basic and applied sciences. Here I present for the first time an analytical treatment of the thermal breakage problem of a semi-flexible polymer model that is asymptotically exact in the low temperature and high friction limits. Specifically, I provide analytical expressions for the breakage propensity and ra...

The purpose of this study is to measure the size distribution of blasted rock using the digital image processing software “SplitDesktop system” in order to evaluate the efficiency of blasting operation. Site of study is a limestone quarry producing limestone for cement manufacturing. Fragmentation is the ultimate measure of efficiency of any production blasting operations. The degree of fragmen...

a r t i c l e i n f o Keywords: Loose agglomerates Breakage Discrete element method Fine particles This paper presents a numerical study of the breakage of loose agglomerates based on the discrete element method. Agglomerates of fine mannitol particles were impacted with a target wall at different velocities and angles. It was observed that the agglomerates on impact experienced large plastic d...
