sometimes the need for non-circular ducts arises in many heat transfer applications because of lower pressure drop of non-circular cross section such as square duct compared to circular tube, particularly in compact heat. but square cross section has poor heat transfer performance and it is expected that using a nanofluid as a new heat transfer media may improve the heat transfer performance of...

introduction: one of the main sections of warm up is stretching which the importance of them is static and dynamic stretching. the purpose of this study was to examine the effects of static and dynamic stretching within a pre-exercise warm-up on the static and dynamic in soccer players. materials and methods: eighteen physical education female students (height: 159.68 ± 5.94 cm; mass: 60.21 ± 5...

In this paper, the energy absorption features of tri-layer explosive-welded deep-drawn cups subjected to quasi-static axial compressive loading are investigated numerically and experimentally. To produce the cups, tri-layer blanks composed of aluminum and stainless steel alloys were fabricated by an explosive-welding process and formed by a deep drawing setup. The quasi-static tests were carrie...

Scheduliig strategies for multiprocessor DSP are classified into four types: fully-dynamic, static-assignment, self-timed, and fully-static. The concept of static scheduling (self-timed or fullystatic) is extended to handle non-deterministic actors in the proposed quasi-static scheduling. Quasi-static scheduling minimizes run-time overhead with increased compilation complexity, thus adequate fo...

In this paper, nonlinear static analysis of moderately thick plate made of functionally graded materials subjected to mechanical transverse loading is carried out using dynamic relaxation method. Mindlin first order shear deformation theory is employed to consider thick plate. Discretized equations are extracted for geometrically nonlinear behavior analysis.Loading Conditions and boundary condi...

The article generalizes the description of tidal forces to case geodesics with non-zero angular momentum in metric static spherically symmetric black holes. We show that geodesic deviation equation can be diagonalized even non-radial free motion a test body gravitational field. present expressions for spatial components force metric. also solve Schwarzschild and demonstrate how presence its mag...
