Introduction Recent history has seen the market for Gallium Nitride (GaN) devices grow dramatically with the LED chip market alone predicted to reach $3.4 billion by the end of 2003. Combine this with the emergence of next generation DVD players, which use the GaN blue laser technology, unique GaN high power/high frequency devices and GaN photodetectors and the importance of GaN technology can ...

Texas Instruments (TI) reserves the right to make changes to its products or to discontinue any semiconductor product or service without notice, and advises its customers to obtain the latest version of relevant information to verify, before placing orders, that the information being relied on is current. TI warrants performance of its semiconductor products and related software to the specific...

this paper presents a mathematical model for a flow shop scheduling problem consisting of m machine and n jobs with fuzzy processing times that can be estimated as independent stochastic or fuzzy numbers. in the traditional flow shop scheduling problem, the typical objective is to minimize the makespan). however,, two significant criteria for each schedule in stochastic models are: expectable m...

Image restoration is one of classical inverse problems in image processing and computer vision, which consists of the recovering information about the original image from incomplete or degraded data. In this paper, we consider the problem of reduction of ringing that appears after image resampling. We introduce a novel method for image restoration, based on a quasi-solution method for a compact...

This paper describes a processor and an inter-processor communications interface integrated on a single chip for use in a distributed processing system. The system is based on work of the electronic systems design and parallel processing group at the Nottingham Trent University. The four main elements of the chip design are processor, memory, communication interface and packet routing switch al...

A simple analytical method is presented that shows some potential for application to the problem of extracting attenuation and backscatter coefficients in an inhomogeneous atmosphere from the return signal of a monostatic single-wavelength lidar system. The method assumes the validity of the single-scattering lidar equation and a power law relationship between backscatter and attenuation. For o...

This paper presents a new image-based parking space detection algorithm, the algorithm is based on a joint decision on multi-feature image processing algorithms, according to the data threshold of variance, correlation and edge-point density joint adjudicate the seize of paring space, it has a high recognition rate. And then the authors transplanted this algorithm into the FPGA platform, the ha...

One of the most compelling issues in the design of wireless communication components is to keep power dissipation between bounds. While low-power solutions are readily achieved in an applicationspecific approach, doing so in a programmable environment is a substantially harder problem. This paper presents an approach to lowpower programmable DSP that is based on the dynamic reconfiguration of h...
