Abstract: With the help of fractal geometry used to model the intermittency of energy input from wind to wave components, the theoretical spectra of the equilibrium range in wind-generated gravity waves proposed by Phillips are ...

Abstract: Lead (Pb)acid batteries are a lowcost power source for applications ranging from hybrid and electric vehicles (HEVs) to largescale energy storage. Efficient simulation, design, and management systems require the development ...

Abstract: Stateofcharge (SOC) estimation for valveregulated leadacid (VRLA) batteries is complicated by the switched linear nature of the underlying dynamics. A first principles nonlinear model is simplified to provide two switched ...

Abstract: Most of the allowable design strain in high-temperature component occurs in the primary creep stage, so the accumulation of creep strain in this stage must be considered. Performance degradation of 12Cr1MoVG steel during ...

Abstract: Using a process denoted here as the empirical mode decomposition and the Hilbert spectral analysis, the ages of the seiches on the Caribbean coast of Puerto Rico are determined from their dispersion characteristics with ...

Abstract: Failure risk assessment of pressure vessels and piping systems is an important part of their integrity management. Obviously, there are many shortcomings in risk analysis using only traditional procedures, which are mostly ...
