In this paper, the 3-user Gaussian MIMO interference channel is considered. The asymmetric distribution of the DoF, where different users have different number of DoF, is studied. Two cases are presented, the first is when all transmitters and receivers have equal number of antennas M , the other when the transmitters have M antennas each, while the receivers have N antennas each. It is assumed...

Wear coefficient is an important wear parameter. However, its value is often determined from wear tests which are conducted without taking into account both their transient wear and steadystate wear. This has resulted in wear coefficient values varying greatly from one case to another when they are determined by different investigators, making meaningful comparison difficult. Research work done...

1) Hydraulic Analysis of the Emergency Core Spray System in a BWR The emergency spray system of a BWR delivers cold water to the core after a large-break loss of coolant accident has emptied the reactor vessel. The system comprises a large water pool, a pump, a spray nozzle and connecting pipes (Figure 1). All pipes are smooth round tubes made of stainless steel with 10 cm internal diameter. Th...

design models of multi- stage, axial flow compressor are developed for gas turbine engines. axial flow compressor is one of the most important parts of gas turbine units. therefore, its design and performance prediction are very important. one-dimensional modeling is a simple, fast and accurate method for performance prediction of any type of compressors with different geometries. in this appro...

â â â â â â â â â â â  â  abstract â  the foreign exchange market (fx market) accounts for 40% of the total volume of the world’s e-commerce by its own. based on statistics, sometimes up to 90 per cent of the traders lose their total capital in this market just within six months to one year and leave this market. the probability of loss in the fx market can be estimated by probability theory....

in this paper the reflection coefficient of electromagnetic wave incidence on the walls of the buildings and obstacles that occurs in mobile communication path was modified by solving the riccati nonlinear equations. for this purpose, the building walls are assumed inhomogeneous layers where their permittivity changes as function of the wall thickness. using this reflection coefficient, a new p...

The main objective in this paper is creating a method for one-dimensional modeling of multi stage axial flow turbine. The calculation used in this technique is based on common thermodynamics and aerodynamics principles in a mean stream line analyses. In this approach, loss models have to be used to determine the entropy increase across each section in the turbine stage. Finally, the analysis an...
