IEEE transactions on power electronics, 2019
Torque ripple has been a critical issue for high-performance applications using permanent magnet synchronous machines (PMSMs). An efficient approach to minimize torque ripple is to control the stator current to follow an optimized current reference ...

IEEE transactions on industrial electronics (1982. Print), 2019
Open-phase fault may lead to motor efficiency and performance degradation. Various fault-tolerant methods have been proposed to reconfigure the controller and to track the sinusoidal current references.

Journal of Climate, 2018
Global changes, such as human activities and climate change, increase the odds of worsening drought. The Gravity Recovery and Climate Experiment (GRACE) satellite provides an opportunity to monitor drought levels by the total amount of water, instead of ...

Let us begin with the following proposition formulated in the preceding chapter: it is all the more difficult to change an organization when the actors in the organization – leaders as well as employees – have a poor understanding of how it functions.

Leadership: A Frame of Reference
Management Science, 1957The word “leadership” has been widely used. Political orators, business executives, social workers, and scholars employ it in speech and writing. Yet, there is widespread disagreement as to its meaning. Among social scientists, the theoretical formulations of the leadership concept have continued to shift, focusing first upon one aspect and then upon ...

The objective of this chapter is to provide a frame of reference for the study’s research questions. I will therefore introduce the innovation concept (section 2.1) by distinguishing between innovation as an outcome (section 2.1.1) and innovation as a process (section 2.1.2).

The culture and the politics of early modern England have both inspired prodigious quantities of scholarship. These subjects have normally been studied separately, however, by experts trained in different disciplines, employing different tools, asking different questions and often taking little notice of each other’s preoccupations. The division partly
