This paper presents a methodology for the detection of broken rotor bar fault and power quality (PQ) disturbances in the supply to induction motor. These faults lead to increase in the temperature and decrease in the efficiency of the induction motor. Wavelet transform is applied to the stator current, for the extraction of the signature of the fault. These wavelet coefficients are fed as input...

the aim of the current study is to amplification the regularity region encompassed the mutations changing the myostatin gene express and also to determine sequential analysis. the blood samples taken from 12 najdi cattles in najdi cattle station in shushtar city, khuzestan province. then the dna extracted to amplification 730bp and 561bp fragments. sequencing was performed after the precision i...

spinal cord injury (sci) results in up regulation and/or down regulation of several genes that may affect neuronal death and subsequent loss of motor function and also neuropathic pain. to expand a practical therapy, it is essential to recognize the specific molecular pathways altered as a function of time after spinal cord injury. this will help to develop strategies for positive manipulation ...

We discuss the dynamics of signatures in the light of recent findings in motor learning, according to which a signature is a highly automated motor task and, as such, it is stored in the brain as both a trajectory plan and a motor plan. We then conjecture that such a stored representation does not necessarily include the entire signature, but can be limited to only parts of it, those that have ...

in this paper, a new field oriented control scheme with maximum torque for permanent magnet hysteresis synchronous (pmhs) motor has been presented. vector control method provides significant improvement to the dynamic performance of ac motors but in this method d- axis current is controlled such as the ratio of motor torque to motor current is a maximum, then the dynamic performance will be ver...

Three-phase induction motors (IMs) are considered an essential part of electromechanical systems. Despite the fact that IMs operate efficiently under harsh environments, there many cases where they indicate deterioration. A crucial type fault must be diagnosed early is stator winding faults as a consequence short circuits. Motor current signature analysis promising method for failure diagnosis ...

Despite the growing growth of technology, handwritten signature has been selected as the first option between biometrics by users. In this paper, a new methodology for offline handwritten signature verification and recognition based on the Shearlet transform and transfer learning is proposed. Since, a large percentage of handwritten signatures are composed of curves and the performance of a sig...

The trend to use inverter drives in industry is well established. It is desirable to monitor the condition of the motor/drive combination with the minimum of system intervention and at the same time retaining compatibility with the latest generation of AC PWM vector drives. This paper studies the effect of stator resistance asymmetry on the performance of the motor driven by a latest-generation...
