Parallel slotting technique is applied in both radiating patch and ground plane to achieve the size reduction of about 84%. Ansoft Designer V2 is emp...

OBJECTIVE To examine how the retail environment in which tobacco is sold has changed because of the slotting fees and trade promotions paid by the tobacco companies. Public policy options for dealing with this environment are also evaluated. DATA SOURCES A literature review, telephone interviews, and observation. RESULTS The tobacco companies have been dramatically increasing the volume of ...

The traditional Economic Order Quantity (EOQ) model ignores the physical limitations of distribution practices. Very often distribution centers (DC) have to deliver merchandize in manufacturer-specified packages, which can impose restrictions on the application of the economic order quantity. These manufacturer-specified packages, or ship-packs, include cases (e.g., cartons containing 24 or 48 ...

Solid rotor induction machines are still used in high-speed systems. A two-dimensional field-circuit model based on the finite element method and complex magnetic vector potential has been shown as a very time-effective tool analysis of their steady states compared to time-domain models. This continuation work presents validated computational algorithm that enables inclusion nonsinusoidal and/o...

As the development of hydrodynamic torque converters (HTCs) points toward increasing pump input power and rotation speed, negative effects cavitation are worsening. Most studies focus on suppressing fluid machinery to attenuate cavitation, such as noise, vibration, blade damage. Therefore, we proposed two stator suppression slotting methods suppress in HTCs: (1) both sides pressure suction (2) ...

For the estimation of the autocorrelation and the auto-spectral density from irregularly sampled laser Doppler data sets three types of estimators are known, the slotting technique, the direct spectral estimation and the interpolation with filter correction. In this paper similar estimation techniques are discussed for the cross-correlation and the cross-spectral density case of two randomly sa...
