Near-fault ground motions have caused very much damage in the vicinity of seismic sources during recent earthquakes. It is well known that under specific circumstances, intensive ground shakings near fault ruptures may be characterized by short-duration impulsive motions. This pulse-type motion is generally particular to the forward direction, where the fault rupture propagates towards the site...

This paper concentrates on a new procedure which experimentally recognises gears and bearings faults of a typical gearbox system using a least square support vector machine (LSSVM). Two wavelet selection criteria Maximum Energy to Shannon Entropy ratio and Maximum Relative Wavelet Energy are used and compared to select an appropriate wavelet for feature extraction. The fault diagnosis method co...

Objective Bayesianism has been criticised on the grounds that objective Bayesian updating, which on a finite outcome space appeals to the maximum entropy principle, differs from Bayesian conditionalisation. The main task of this paper is to show that this objection backfires: the difference between the two forms of updating reflects negatively on Bayesian conditionalisation rather than on objec...

Large corporations can achieve significant cost savings by developing and employing a sophisticated and continuously updated, billing and credit policy. Days of sale outstanding (DSO) is a major cost driver for corporations with large revenues, as this leads to an increased risk of default, increased dunning and collection costs, a non-optimal billing procedure with attendant costs and perhaps ...

To improve the performance and the usability of the speech recognition devices, it is necessary for most applications to allow users to enter new words or personalize words in the system vocabulary. The voicetagging technique is a simple example of using speaker dependent spoken samples to generate baseform transcriptions of the spoken words. More sophisticated techniques can use both spoken sa...

many researchers have been efforted to identify the shape of distribution of stress and strength of castellated beam and base on that, offer a method for design that members. through this methods, comparing virendil method by simplicity and reasonable results, have been used widly. regardless from shortcoming of this method, there is two idea for distribution of stresses via primary bending in ...

salicylic acid play an important role in plants physiological processes. in this research the effect of salicylic acid on induction of somatic embryogenesis and plant pigments synthesis in the phloem and petiole explants of carrot in the b5 medium was investigated. we added treatments with 0, 0.5, 1.5, 2 and 3 mm to culture medium by experimental base on the randomized design to investigate the...

The computational fluid dynamics is concentrated on the forced air cooling of the CPU using a heat sink. This paper utilizes CFD to identify a cooling solution for a desktop computer, which uses an 80 W CPU maximum whereas this number will be increased in the range of 70-120W in the forthcoming desktop computer systems. The design is able to cool the chassis with one fan with air blowing over h...
