In this paper, the torque production of fractional slot concentrated winding (FSCW) permanent magnet synchronous machines (PMSM) are analyzed from the perspective of the air-gap field harmonics modulation accounting for slotting effect. It is found that the average torque of FSCW PMSM is produced by both the principle of conventional PMSM and the magnetic gearing effect. A finite element analys...

This paper presents an analytical study of the air-gap magnetic field a Surface Permanent Magnet (SPM) linear machine under no load. By means method images, complex expression conductor, inside air gap between two smooth iron surfaces, is retrieved. Then, integrating conductor expression, formulation current sheet and thus one SPM, using vertical sheets, obtained. At last, no-load for generic t...

The purpose of this paper is to present a new hybrid analytical model (HAM) based on winding function theory (WFT) for electromagnetic analysis performance one typical unbalanced two-phase induction motor (UTPIM). Different indexes modeling such as distribution, slotting effect, and magnetic saturation can be accurately considered by using the proposed HAM. For obtaining technique, reformulated...

An unsettled area of antitrust law is the regulation of the competitive process for product distribution and promotion. Competition for distribution involves vertical contracting with respect to product placement, promotional activity, or the decision to carry a particular product. This process includes controversial practices recently subject to intense scrutiny such as slotting allowances, lo...

We present an efficient and accurate reconstruction technique for computed tomography (CT) images from a geometrically unconstrained set of ray sums. Current CT-scanners are immobile. However, a new era in x-ray production could usher in new, lightweight, flexible and portable x-ray devices. The proposed device, currently under development, is envisioned as a flexible band with tiny x-ray emitt...

A microengineered array to sample clonal colonies is described. The cells were cultured on an array of individually releasable elements until the colonies expanded to cover multiple elements. Single elements were released using a laser-based system and collected to sample cells from individual colonies. A greater than an 85% rate in splitting and collecting colonies was achieved using a 3-dimen...

The FAMA-NCS protocol is introduced for wireless LANs and ad-hoc networks that are based on a single channel and asynchronous transmissions (i.e., no time slotting). FAMA-NCS (for floor acquisition multiple access with non-persistent carrier sensing) guarantees that a single sender is able to send data packets free of collisions to a given receiver at any given time. FAMA-NCS is based on a thre...

Accurate prediction of the energy consumption is critical for energy-efficient production systems. However, the majority of existing prediction models aim at providing only point predictions and can be affected by uncertainties in the model parameters and input data. In this paper, a prediction model that generates prediction intervals (PIs) for estimating energy consumption of a milling machin...
