INTRODUCTION: Both theoretical and experimental evidence indicate that physiological deformations of bone tissue are not sufficient to stimulate osteocytes, the sensory cells in bone [1,2]. Indeed, it is believed that the interstitial fluid flow in the lacunar-canalicular porosity (PLC) plays an important role in amplifying bone tissue strains to the level osteocytes can sense[1,2], which is at...

Signal generation is one of the most critical problems in the microwave and millimeter-wave communication market. The demands of greater stability and low phase noise further increase complexity in the circuit design. Signal generation in the millimeter-wave bands can be realized either directly by an oscillator or by multiplication from a lower frequency. An effective solution is to multiply t...

This paper deals with the active vibration control of beam like structures with distributed piezoelechic sensor and actuator layers bonded on top and bottom surfaces of the beam. A finite element model based on Euler-Bernoulli beam theory has been developed. The contribution of the piezoelectric sensor and actuator layers on the mass and stiffness of the beam is colisidered. Three types of clas...

proper operations of transformer have several issues such as; preventing of unscheduled removal’s, increasing of reliability and continues supply of consumer demand. this result would be obtained that load and harmonic orders of sensitivity transformer at intervals appropriate for next hours and days is predicted to by selecting optimal utilization coefficient, reduction life of transformer is ...

A method of modelling multi-limbed saturated reactors under dynamic and steady-state conditions, allowing for both the electrical interconnection of the windings and the core construction, is presented. A selection of results from a digital computer program based on the simulation are given, illustrating the dynamic response of the reactor model to parameter changes under system energisation. T...

Multiphase induction machine; Rectangular air–gap flux; Third harmonic injection; Eleven-phase Abstract This paper presents a modified V/f control strategy using neural network with an improved flux pattern using third harmonic injection for multiphase induction machines. The control objective is to generate a nearly rectangular air–gap flux, resulting in an improved machine power density for t...

The paper concerns the validation of a method for solving elastodynamics problems for cracked solids. The proposed method is based on the application of boundary integral equations. The problem of an interface penny-shaped crack between two dissimilar elastic half-spaces under harmonic loading is considered as an example.
