Abstract
In this paper, new descriptor observer design approaches are presented for multivariable systems with measurement noises. If the system matrix is stable, the proposed modified proportional and derivative observer technique allows us not only to decouple the measurement noise in any forms completely, but also obtain accurate estimations of both system states and measurement noises. If the system is detectable and the noise is bounded, it has been shown that two design parameters can provide more degrees of freedom. In this context, th ....etc

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

Reduced Instruction Set Computer (RISC) processor

INTRODUCTION
This project is aimed at designing of a Reduced Instruction Set Computer (RISC) processor using the Verilog Hardware Description Language (HDL). For a long time, programming languages such as C, Pascal & FORTRAN were being used to describe the computer programs that were sequential in nature. Similarly in the digital design field, designers felt the need for a standard language to describe digital circuits. Thus, HDL came into existence. HDL allowed ....etc

A NEW REDUCED SIZE MICROSTRIP PATCH ANTENNA WITH FRACTAL SHAPED DEFECTS


Abstract With development of communication with integration
technology, size reduction of microstrip antennas is becoming an
important design consideration for practical applications. Here a new
microstrip antenna with Koch shaped fractal defects on the patch
surface is presented. Using this method, the overall electric length
of the antenna is increased largely and hence the size of antenna is
reduced t ....etc

Abstract

A robust/adaptive stochastic observer is presented for stochastic nonlinear dynamics having excessive uncertainties. It was shown through a new theorem that the proposed nonlinear robust sliding mode observer has very accurate state estimate error characteristic. The observer uses the sliding mode technique for the robustness and a deterministic adaptive law to guarantees a globally asymptotically convergence observation error. Finally, an example is given to illustrate t ....etc

Abstract:
The field oriented control emerged as an important approach for the control of AC machines, and continues to be explored and developed in the literature. The estimation of the rotor flux from the measurable variables was the only method used to implement the vector control of the induction machine. To replace the estimator based on the mathematical model of the system, which can lead to unintended errors due to uncertainties on the model and on the measures we use an appropriate observer.

Difference between CISC and RISC:
CISC stands for Complex Instruction Set Computer. Most PC's use CPU based on this architecture. For instance Intel and AMD CPU's are based on CISC architectures. Typically CISC chips have a large amount of different and complex instructions. In common CISC chips are relatively slow (compared to RISC chips) per instruction, but use little (less than RISC) instructions. MCS-51 family microcontrollers based on CISC architecture.
RICS stands for Reduced Instruction Set Computer ....etc

REDUCED EMISSIONS OF OXIDES OF NITROGEN IN SHIP ENGINES




INTRODUCTION

Oxides of nitrogen emission from ship engines are significant on a global level. These emissions participate in the formation of photochemical smog and acid rain. Here we look at to some ways by which these emissions can be reduced
