in the present study, a model of a large lithium polymer (li-po) battery for use in the simulation of hybrid electric vehicles (hevs) is developed. to attain this goal, an equivalent circuit (ec) consisting of a series resistor and two rc parallel networks is considered. the accuracy and the response time of the model for use in an hev simulator are studied. the battery parameters identificatio...

Due to the simple structure, high torque density, low maintenance, and high efficiency, brushless direct current (BLDC) motors are widely used in automation and industrial applications. A control strategy based on single current sensor is proposed for a four-switch three-phase BLDC motor system to lower cost and improve reliability. The whole working process of the BLDC motor is divided into si...

In this paper the design of a new high-speed current mode BiCMOS logic circuits isproposed. By altering the threshold detector circuit of the conventional current mode logic circuitsand applying the multiple value logic (MVL) approach the number of transistors in basic logicoperators are significantly reduced and hence a reduction of chip area and power dissipation as wellas an increase in spee...

The current high level of interest in neutrino properties is well justified. Neutrino properties (such as masses, mixings, magnetic moments etc.) are of interest for a variety of reasons: (i) in their own right as fundamental parameters and (ii) as harbingers of new physics beyond the standard model (if e.g. mi 6= 0, θi 6= 0, μi 6= 0 etc.). I will not review here the kinematic limits on masses ...

Although teacher learning has often been overlooked in discussions surrounding classroom practice, it is believed that learning cultivates the resilience and vitality needed for teachers to thrive. Teachers have often been required to demonstrate a high level of skill and professionalism as they orchestrate tasks that maximise student engagement. Their work has consequently been compared to tha...
