This paper investigates the ergodic capacity of multipath channels in the wideband regime with limited feedback. Our work builds on recent results that have established significant capacity gains achievable in the wideband/low-SNR regime, when there is perfect channel state information (CSI) at the transmitter. Furthermore, this benchmark gain can be obtained with just 1-bit of CSI at the trans...

Two companion papers describe an internally consistent general power theory valid for instantaneous and average power for systems with any number of wires, under conditions of unbalance, distortion or dc components. Measuring apparent power and power factor under non-ideal conditions, even in typical three-phase four wire systems, needs the resistances of the wires, particularly the neutral wir...

It is a fundamental decision making process in container terminals to allocate container transporting works among ALVs. Nowadays, container terminals tend to be larger in storage space and more efficient in handling. As a result, estimations of ALV travel times could be inaccurate, the scale of ALV work allocation could be quite large, and a fixed handling sequence could be hardly ensured befor...

The aim of this paper is to investigate and detect the multiple faults in machines using broken rotor bar and eccentricity fault frequencies techniques. It is proposed that using both current and instantaneous power signals simultaneously, will detect the multiple faults reliably, specifically using broken rotor bar fault frequencies and eccentricity fault frequencies under various load conditi...

Peak instantaneous power is a prognostic index of LV function but is difficult to measure. It is relatively load independent when corrected by preload (EDV2). Easier to acquire power estimates have been proposed--including mean and simplified power. These require only echo Doppler flow and cuff pressures, but their relationship to invasively derived results has not been studied. Using a well-va...

In this study, the vibration behavior of functional graded (FG) circular and annular nanoplate embedded in Visco-Pasternak foundation and coupled with temperature change is studied. It is assumed that a uniform radial magnetic field acts on the top surface of the plate and the magnetic permeability coefficient of the plate along its thickness are assumed to vary according to the volume distribu...

A deterministic inventory model with two levels of storage (own warehouse and rented warehouse) with non-instantaneous deteriorating items is studied. The supplier offers the retailer a trade credit period to settle the amount. Different scenarios based on the deterioration and the trade credit period have been considered. In this article, we have framed two models considering single warehouse ...

This paper inspects the misaligned motors by using diagnostic medium such as current, flux and instantaneous power signal. Misalignments in machines can cause decrease in efficiency and in the long-run it may cause disastrous failure because of unnecessary vibration, stress on motor & bearings and short-circuiting in stator and rotor windings. The measurements have been performed at full-load t...

This study compares the explanatory power of Martin Fishbein's and Icek Ajzen's theory of reasoned action, Icek Ajzen's theory of planned behavior, and a modified version of the theory of planned behavior, which includes a measure of moral obligation, to predict insurance agents' ethical intentions towards their clients. Two hundred and forty-five insurance agents in the U.S. were surveyed, wit...
