Data Throughput Evaluation of Internet Users over UMTS Wireless Network
Volume 1, Issue 3 , June 2007, Pages 1-7
Abstract
Although voice is a mandatory service in the wireless telecommunication networks, most of new data services are based on Internet. These services include http, telnet, SMTP, etc. In addition, mobile channel is a multipath fading channel. TCP/IP performance in the wired systems depends on the link congestion ... Read MoreUsing Multiple Description for a JPEG Coder
Volume 1, Issue 3 , June 2007, Pages 9-16
Abstract
In this paper we propose a good way to decrease the effects of noisy channels on the JPEG images using multiple description coding. In this way we can compress the data of image with a better signal to noise ratio. first, we use over sampling to increase the redundant of the data, then we divide the ... Read MoreNew Robust Nonlinear Controller Design Based on Predictive Control for Industrial Processes
Volume 1, Issue 3 , June 2007, Pages 17-23
Abstract
In this paper a new sliding mode controller based on predictive control is used for the first order system, which is a good model for the industrial process. In this method a developed predictive control is used to optimize the sliding mode control including sliding surface and switching function coefficient ... Read MoreStator Flux Oriented Vector Control of Interior Permanent Magnet Synchronous Motors with Maximum Power Factor Per Ampere Strategy
Volume 1, Issue 3 , June 2007, Pages 25-38
Abstract
Permanent magnet synchronous motors attract more attentions in motion control application in recent years. In this paper a novel stator flux oriented vector control scheme with maximum power factor to current trajectory is presented for a permanent magnet synchronous motor. This system is ... Read MoreSensor Network Self-Localization Using Fuzzy Logic
Volume 1, Issue 3 , June 2007, Pages 39-46
Abstract
Location awareness is an important capability for a series of enhanced wireless businesses. sensor networks are dense wireless networks of small low cost sensors, which collect and disseminate environmental data, for monitoring, military application and so on. Localization is an unconstrained optimization ... Read MoreNumerical Solution of Electronic Transport in Nanotransistors in Ballistic Regime for One and Two Dimensional System
Volume 1, Issue 3 , June 2007, Pages 47-53
Abstract
For accessing to higher speed and more densities in packaging, FET structures have become small increasing from day to day. Devices as small as 18nm can still exhibit acceptable transistor characteristics but At such small sizes, the nature of carrier transport in the device begins to change. In such ... Read MoreWeb Software Evaluation Using Artificial Neural Networks
Volume 1, Issue 3 , June 2007, Pages 55-62
Abstract
Software testing is one of the most important phases in the software development procedure which ensures the accordance of the software and its description. Testing is mainly a manual task accomplished by the human operators. This results in increasing the cost and time of the software ... Read MoreExponential Non-Linear Carrier Controller
