Simulation of MIMO Antenna Systems in Simulink
and Embedded Matlab



Abstract

Multi-Input Multi-Output (MIMO) has emerged as
a hot topic in wireless communications during the last decade.
This is due to possible dramatic increases in reliability and
capacity as compared to single-antenna solutions. However, much
of the existing theoretical results are based on very simplistic
models of the antennas and transciever circuitry.

Researchers at the University of Southampton have created a type of memory glass of computer that could reduce costs of medical imaging.

The team, led by Professor Peter Kazansky in the Centre for research in Photonics of the University, used nano-structures to develop millimeter devices that change the way light moves through glass.

Known as polarization glass converters space varying monolithic, these devices redirect light in 'eddies' which can then be read in a manner similar to data in optical fibers.

The information can then be written ....etc

SLOT VIEW SIMULATION OF WIND ELECTRICAL SYSTEMS



ABSTRACT
As a result of increasing environmental concern, more and more electricity is generated from renewable sources. One way of generating electricity from renewable sources is to use wind turbines. A tendency to erect more and more wind turbines can be observed. As a result of this, in the near future wind turbines may start to influence the behaviour of electrical power systems. Therefore, adequate models to study the impact ....etc

Queueing Theory / Poisson process



General

Poisson process is one of the most important models used in queueing theory.
Often the arrival process of customers can be described by a Poisson process.
In teletraffic theory the customers may be calls or packets. Poisson process is a viable
model when the calls or packets originate from a large population of independent users.
In the following it is instructive to think that the Poisson process we consider represents
discrete arrivals (of e.g. calls ....etc

Introduction
This package presents computer models of electric machines leading to the assessment of the dynamic performance of open- and closed-loop ac and dc drives. The Simulink/Matlab implementation is adopted because of its inherent integration of vectorized system representations in block diagram form, of numerical analysis methods, of graphical portrayal of time evolutions of signals combined with the simple implementation of the functionality of controllers and power electronic excitations. The development o ....etc

Simulation generally involves some kind of model or simplified representation. During the course of a simulation, the model mimics important elements of what is being simulated. A simulation model may be a physical model, a mental conception, a mathematical model, a computer model, or some combination of all of these. Computer simulation is currently used in a wide range of applications, since physical models are often relatively expensive to build and unwieldy to move. Queuing systems are used to characterize a broad class of processes sharing ....etc

Abstract

Simulation based control schemes for a low-energy building system are introduced and compared in this paper. The simulation of a low-energy system is firstly constructed and a fast two-stage optimisation method is proposed to find the optimal control policy in short time. A Model Predictive Control (MPC) scheme and a Hierarchical Fuzzy Rule based Control (HFRC) scheme that is tuned online by a reinforcement learning (RL) agent are introduced. The MPC scheme runs the simulation ....etc

Computer Simulation of Sputtering and Collision Cascades in Ionic Materials


Sputtering

Definition

Sputtering is the removal of surface atoms due to energetic particle bombardment.
This is caused by collisions between the incoming particles and the atoms in the near surface layers of a solid.

Applications

Sputtering is not just an unwanted effect which destroys cathodes and contaminates plasmas.
It is used in many modern industrial processes includ ....etc
