sensorless speed torque control of induction machines has been widely used in many industrial applications. the simple method of direct vector control can provide tacholess control as well as more complex approaches. in this method, the motor flux can be obtained by measuring voltage and current and integrating motor back electromotive force. the only required motor parameter is stator resistan...

A device which comprises three parts, electromotor, screw and cable, is proposed to suppress the vibration of a single-link flexible manipulator. The manipulator acted on jointly by the device and the load at manipulator’s end-effector is modeled as a cantilever beam with three concentrated loads at two end-points and midpoint. By taking the exserted length of the screw as control variable, the...

Zero-IF receivers are gaining interest because they enable low-cost WLAN OFDM terminals. However, Zero-IF receivers introduce IQ imbalance which may have a huge impact on the performance. Rather than increasing component cost to decrease the IQ imbalance, an alternative is to tolerate the IQ imbalance and compensate it digitally. Current solutions converge too slow for bursty WLAN communication...

We examined the stability of standard curves obtained with use of homogeneous enzyme immunoassay reagents (EMIT; Syva Corp., Palo Alto, CA) for assay of lidocaine, procainamide, N-acetylprocainamide, gentamicin, and theophylline, when stored at room temperature (23-24 degrees C) after reconstitution of the lyophilized materials. Standards were run and curves obtained for as long as 16 days afte...

The Proposed framework is to give a way choice calculation to versatile robots in extensive element/obscure situations. The proposed calculation permits a portable robot to explore through static hindrances, and finding the way keeping in mind the end goal to achieve the objective without crash. The point of the work is to diminish the danger of impacts and time of way following in situations w...

Sense amplifiers plays an important role in memories like Dynamic Random Access (DRAM) and Static Random Access (SRAM) for read and write operations. A sense amplifier compares the bit line voltage and its complement amplifies it to rail to rail output voltages. In this project, we mainly concentrated on the write operation. Sense amplifier is one of the peripheral circuits in memories that are...
