Abstract:The VLSI design industry has grown rapidly during the last few decades. The complexity of the applications increases day by day due to which the area utilization increases. The tradeoff between area and speed is an important factor. The main focus of continued research has been to increase the operating speed by keeping the area and memory utilization of the design as low as possible. ...

An analysis of instrumented vehicle data revealed significant differences in operating mode profiles for vehicle operations in Atlanta, Georgia; Baltimore, Maryland; and Spokane, Washington. Differences in such operating mode characteristics as acceleration rates and cruise speed distributions are important in the development of new emissions models because certain vehicle and engine operating ...

In order to obtain more accurate predicted dynamic steady-state performance with shorter computation time, an available mathematical model is modified and presented. Using this modified model, performance of a typical switched reluctance motor (SRM) under a wide range of variations of operating conditions is obtained and discussed. These include variations of speed, voltage, load and switching ...

The Affinity Laws for fans (and pumps) provide a way of determining new fan or pump speed given fan or pump performance curve data and a desired operating point (combination of flow rate and pressure) that does not fall on the curve. However, the affinity law calculations require using a point on the curve (hereafter referred to as the “basic point”) to determine the new speed. Most references ...

This paper addresses linear quadratic regulation (LQR) for variable speed variable pitch wind turbines. Because of the inherent nonlinearity of wind turbine, a set of operating conditions is identified and then a LQR controller is designed for each operating point. The feedback controller gains are then interpolated linearly to get control law for the entire operating region. Besides, the aerod...

Uniformity in the deposition of granulated fertilizers seed furrow is essential for crop development and productivity. Quantitative (dose flow) qualitative factors (segregation formulation) influence fertilizer distribution throughout its application. This experiment aimed to compare two with different chemical formulations (04-14-08 04-30-10), using helical overflow metering mechanism at three...
