The growing rate of energy consumption is a reason for establishment of new power plants which leads to increment in fault current level. One of the solutions to overcome this problem is utilization of fault current limiters (FCLs). Another concerning issue in energy generation is the satisfactory voltage quality in grid and to deal with it, a power electronic based device, known as dynamics vo...

in this paper the critical strain energy release rate for t300/913 carbon-epoxy laminated composites has been studied using ansys finite element software based on virtual crack closure technique ( vcct ). compact tension ( ct ) specimen has been used for numerical analyses and the geometrical dimensions have been extracted from the existing references. the results obtained from the finite eleme...

cumin (cuminum cyminum) is an annual suitable for the dry and semi-dry areas of iran. recently, farmers have chosen to plant cumin because it requires less water and growth time. however, at harvest time, the resistance of cumin seed to shatter is low and, if careful attention is not paid to this fact, a major portion of the crop can be lost. when the connection force of the seed decreases, see...

A simple simulation method is proposed for calculating partition function ratios with emphasis on computing transition state theory rate constants. Potential energy histograms are calculated in one single high temperature simulation. Partition function ratios can then be computed for a wide range of temperatures from this information. We apply this high-temperature configuration-space explorati...

We study the evolution of the spectral index and the normalization (flux) of the non-thermal component of the electron spectra observed by RHESSI during 24 solar hard X-ray flares. The quantitative evolution is confronted with the predictions of simple electron acceleration models featuring the soft-hard-soft behaviour. The comparison is general in scope and can be applied to different accelera...

introduction: the relative costs of generating energy vary considerably depending on location. since hospital managers confront serious financial problems, they need to look for ways to use energy more efficiently. this study aimed to study the rate of energy use (water, gas and electricity) in a number of hospitals in isfahan from 1378 to 1382 and to compare the results with the available stan...

In this paper, a new method for characterizing the newborn heart rate variability (HRV) is proposed. The central of the method is the newly proposed technique for instantaneous frequency (IF) estimation specifically designed for nonstationary multicomponent signals such as HRV. The new method attempts to characterize the newborn HRV using features extracted from the time–frequency (TF) domain o...
