In the present paper, a complete literatures review of thermal barrier coating applications in diesel engines is performed to select a proper type and to find coating effects. The coating system has effects on the fuel consumption, the power and the combustion efficiency, pollution contents and the fatigue lifetime of engine components. Usually there are several beneficial influences by appl...

A previous paper [Applied Acoustics 66, pp.709-730, 2005] has shown that adding a quadratic residue diffuser (QRD) to the top of a T-shape barrier can provide better barrier performance than an equivalent purely absorptive barrier. In here, we extend the study to look at the performance when a QRD is made absorptive. This paper presents an investigation on the acoustic performance of a few well...

Barrier synchronization is commonly and widely used to synchronize the execution of parallel processor cores on multi-core Network-on-Chips (NoCs). Since its global nature may cause heavy serialization resulting in large performance penalty, barrier synchronization should be carefully designed to have low latency communication and to minimize overall completion time. Therefore, in the paper, we...

background: psychological and behavioral domains are important in coping with type ii diabetes. this study was conducted to assess supportive and coping obstacles in living with type ii diabetes among patients who visited hospitals affiliated to tehran university of medical sciences (tums). methods: this was a cross-sectional study with 600 subjects who participated in the study. data collectio...

In this paper, we consider convex quadratic semidefinite optimization problems and provide a primal-dual Interior Point Method (IPM) based on a new kernel function with a trigonometric barrier term. Iteration complexity of the algorithm is analyzed using some easy to check and mild conditions. Although our proposed kernel function is neither a Self-Regular (SR) fun...

Two dimensional noise barrier studies investigate the insertion loss in the shadow zone of an infinite noise barrier for a coherent line source. Such models are often preferred to avoid the high computational cost of three dimensional models. The major limitation of two dimensional barrier models is the constant cross section of the barrier in the third direction. This paper presents a new solu...

background: although the pap smear is known as one of the effective methods to detect the cervical cancer, a large group of women are reluctant to do the test because of various reasons. therefore, we carried out this study to determine the level of knowledge about cervical cancer and pap smear and the factors influencing the pap test screening among women. methods: in this cross-sectional stud...

The performance of nine different vapor barrier systems comprising polyethylene (PE) membranes were assessed. comprised virgin PE, 100% new regenerated PE and multilayered PE. Membranes joined either with tape suited to the individual system or an adhesive base on butyl rubber. evaluated compared using standard laboratory tests. Chemical analytical techniques physicomechanical tests used. Mecha...
