Abstract Background While near surface residual stress (NSRS) from milling is a driver for distortion in aluminum parts there are few studies that directly compare available techniques NSRS measurement. Objective We report application and assessment of four different evaluating versus depth milled parts. Methods The are: hole-drilling, slotting, cos(?) x-ray diffraction (XRD), sin 2 (?) XRD, al...

In this paper, a broadband rectangular microstrip patch antenna fed by coplanar waveguide feed with two slots in the ground plane is proposed. Investigations are carried out using coplanar waveguide feed with slotting in the ground plane to optimize the broadband operation. A sensitivity analysis shows the variation of return loss with different antenna parameters. This design of broadband ante...

The paper deals with modeling of synchronous reluctance motor (SynRM) accounting for all phenomena responsible for torque ripple. Based on winding function approach, the proposed model consists in computing self and mutual inductances considering no sinusoidal distribution of stator windings, slotting effect and no sinusoidal reluctance variation caused by the rotor saliency. Then, optimal curr...

Laser-Doppler Anemometry (LDA) is used to measure the velocity of gases and liquids with observations irregularly spaced in time. Equidistant resampling turns out to be better than slotting techniques. After resampling, two ways of spectral estimation are compared. The first estimate is a windowed periodogram and the second is the spectrum of a time series model. That is an estimated autoregres...

We develop a general-equilibrium model to capture key features of the retailing and of the manufacturing industry in order to understand how these two industries interact and how labor is allocated between them. We show that the observed shift in employment from manufacturing to retailing, the rise in retailer product assortment and the emergence of slotting allowances in many retail markets ar...

Many warehouse slotting algorithms have overlooked worker ergonomics. This research aimed to develop ergonomics guidelines based upon the back and shoulder postures electromyographic (EMG) responses of deltoid erector spinae muscles when individual items are picked from, or full cases replenished to, different shelf heights In first study two studies, participants lifted small representative pi...
