This paper investigates the replacement of a conventional steel coil spring with composite disc aim minimizing its weight. Simulation in CAD system Siemens NX 12 was used to determine spring’s behavior. The regression functions were stated based on numerical simulation. Based solution minimum weight found using software programmed Matlab. prototype discs manufactured from carbon fibre pre...

This paper studies the load sharing problem among heterogeneous cluster systems. The heterogeneous clusters we consider are time-sharing, and the computers in these clusters have different CPU powers and memory capacities. Load sharing means even workloads among all coordinated computers in the system. As some nodes suffer from high loading, it is necessary to migrate some jobs to the nodes wit...

In this paper, vibration analysis of thick functionally graded beam with simply supported boundary condition under constant axial load is studied. The beam has a uniform cross-sectional area and the mechanical properties of the fungtionally graded beam are assumed to be vary through the thickness of the beam. Fundamental relations, the equilibrium and stability equations based on the displaceme...

During goal-directed tasks, such as lifting low-lying objects, the human motor system regulates the body’s centre of mass (CoM) position to maintain equilibrium and prevent falling [1]. During lifting, any voluntary trunk movement will perturb that equilibrium, which will elicit an automatic postural response requiring the coordinated control of several joints [2]. To actively counter perturbat...
