Abstract By using the CFD (Computational Fluid Dynamics) software, RNG (Renormalization Group) turbulence model and mud shield module are employed to establish a three-dimensional mathematical of scouring around wind power pile foundation. The reliability is verified by literature results. A new foundation protection method proposed. thickness diaphragm protective layer 0.5 cm, 1 2 4 6 8 10 cm....

Japanese local governments have been encouraging public hospitals to use group purchasing of drugs to benefit from the economies of scale, and increase their bargaining power for obtaining discounts in drug purchasing, thus improving their financial situation. In this study, we empirically investigate whether or no...

Proposed and existing power-control systems for directsequence CDMA cellular networks measure instantaneous power, whereas theoretical analyses almost always assume long-term-average or local-mean power control. In this paper, the distinction between the two types of power control is clarified. The outage probability for direct-sequence CDMA systems using instantaneous power control is derived....
