A 2D analytical method for magnetic vector potential calculation in inner rotor surface mounted and surface inset permanent magnet machines considering slotting effects, magnetization orientation and winding layout has been proposed in this paper. The analytical method is based on the resolution of Laplace and Poisson equations as well as Maxwell equation in quasi- Cartesian coordinate by using...

This communication reports a numerical simulation of reentry induction by successive stimulation (S1-S2) that does not require an S1 gradient of refractoriness. The S1 action potential is uniform in space, so before the S2 stimulus there is no refractory gradient. Nevertheless, a unipolar S2 stimulus initiates quatrefoil reentry. The result supports the growing realization that virtual electrod...

In this paper I introduce the concept of "visual prototype" to capture one particular kind of work done by visual representation in the practice of science. I use an example from neuroscience; more particularly, the example of the visual representation of the pattern of convolutions (the gyri and sulci) of the human cortex as this pattern is constructed and used in the practice of mapping the f...

Concurrent objects andmultiparty compatibility. Data types describe values; behavioural types such as multiparty session types [4] and typestate [3] describe interactions. Here we introduce a simple actor language and show how multiparty compatibility [1] can be used to statically type-check systems of concurrent objects whose interfaces evolve dynamically in response to messages. Our program i...

This research aims at discovering the traits and abilities which characterize ideal leaders in the minds of employees in an Iranian context. After employing the strategy of phenomenology to reach the components of ideal leadership, 15 tenured middle managers and employees possessing decent management knowledge in the context were interviewed and after theme analysis, global, basic, and organizi...

This article commences with an elaboration of models of design as a process. It then introduces and describes a knowledge representation schema for design called design prototypes. This schema supports the initiation and continuation of the act of designing. Design prototypes are shown to provide a suitable framework to distinguish routine, innovative and creative design. DESIGN Although there ...
