Permanent Magnet Machines (PMM) with a phase number (m) higher than three allow redundancy and lower torque ripple compared to their three phase counterparts. In this paper, a six phase permanent magnet machine with surface rotor magnets, designed with fractional slot tooth winding is proposed. A stator design with fractional slot tooth winding allows the design of a compact machine through sho...

In this paper, Finite Difference Time Domain (FDTD) is utilized to simulate metamaterials of Double Negative (DNG) origin that refers to those materials having simultaneous negative permittivity and permeability. The problem regarding space formulation is achieved by means of auxiliary differential equation method (ADE), which is easy, reliable and also causal process in nature thus making it p...

We develop a systematic framework for studying target space duality at the classical level. We show that target space duality between manifolds M and M̃ arises because of the existence of a very special symplectic manifold. This manifold locally looks like M×M̃ and admits a double fibration. We analyze the local geometric requirements necessary for target space duality and prove that both manifol...

A field-based new adaptive mesh generator, VEGA (VEctor-following Grid generator for Adaptive mesh), is developed for 2-D core–edge coupled tokamak plasma transport simulations. VEGA can generate timevarying and spatially non-uniform grids by using a stretching function. It provides two operation modes for generating non-uniform radial distributions. One is so-called ionmodewhere the grid is au...

Hidrocystoma is a rare cystic lesion arising from the sweat glands, and is classified into apocrine and eccrine variants, with the majority being of apocrine nature [1]. It is usually found in the head and neck region, and commonly affects the periorbital area [1, 2]. Apocrine hidrocystoma is characterized histopathologically by the presence of a unilocular or multilocular cyst situated in the ...

The article deals with an improved treatment of wall models for the simulation turbulent flows in framework Immersed Wall Boundaries on Cartesian grids. emphasis is put implementation a Lattice-Boltzmann Method solver without loss generality, since proposed approach can be used Navier–Stokes-based solvers straightforward way. model relies combination several key elements, namely i) removal grid...

Given an embedded cylinder in an arbitrary surface, we give a gauge theoretic definition of the associated Goldman flow, which is a circle action on a dense open subset of the moduli space of equivalence classes of flat SU(2)-connections over the surface. A cylinder in a compact nonorientable surface lifts to two cylinders in the orientable double cover, and the composite flow is the compositio...

the effect of single and double-layer anti-reflective coatings on efficiency enhancement of silicon solar cells was investigated. the reflectance of different anti-reflection structures were calculated using the transfer matrix method and then to predict the performance of solar cells coated by these structures, the weighted average reflectance curves were used as an input of a pc1d simulation....

The most popular way to animate fluids is to solve the underlying physical equations. In this poster we introduce a general framework for physically-based fluid animation: the multi-layer Navier-Stokes solver. The Navier-Stokes equations are solved on a series of nesting grids in successive passes. Then the velocity and pressure fields of different layers are synchronized through interpolations...
