What Is Scilab? There exist two categories of general scientific software: computer algebra systems that perform symbolic computations‚ and general purpose numerical systems performing numerical computations and designed specifically for scientific applications. The best-known examples in the first category are Maple‚ Mathematica‚ Maxima‚ Axiom‚ and MuPad. The second category represents a larger market dominated by MATLAB. Scilab belongs to this second category. Scilab is an interpreted language

communications and digital signal processing. Introduction to mobile radio communications. Spread spectrum. Modulation techniques. Introduction. Mobile communication has seen an unprecedented increase in the number of users over the past years. Its success in part is due to the various technologies that have been developed. It is not unlike other stationary communication systems in many respects however it does differ in others‚ one obvious one being the environment the signal and data propagate

David Perez Prof. David Finley ENG101/ENH255 8 September 2010 Smoke Signals Character Analysis #1 Sherman Alexie created a character named Victor who is portrayed in Alexie’s work this is what it means to Say Phoenix‚ Arizona. Alexie’s short story was also developed into a film by Chris Eyre named Smoke Signals. Victor is the main character in both the movie and the film and they are about him and his travel on the way to Arizona where is father passed away. With him he takes Thomas Builds-the-Fire

Algorithms In OFDM Systems Vineetha Mathai Dept. of Electronics Engineering‚ Madras Institute of Technology‚ Chennai-600044‚ India. e-mail: vineethamathai@yahoo.in Abstract—The channel estimation can be performed for analyzing effect of channel on signal by either inserting pilot tones into all of the subcarriers of OFDM symbols with a specific period or inserting pilot tones into each OFDM symbol. The block type pilot channel estimation has been developed under the assumption of slow fading channel

phase-lock-loop (PLL) is commonly used in microprocessors to generate a clock at high frequency (Fout=2GHz for example) from an external clock at low frequency (Fref = 100MHz for example). The PLL is also used as a clock recovery circuit to generate a clock signal from a series of bits transmitted in serial without synchronization clock (Figure below). The PLL may also be found in frequency demodulation circuits‚ to transform a frequency varying waveform into a voltage. The PLL uses a high frequency

normal retinal images the AVR ratio varies from 2/3 to 3/4.As diabetic retinopathy progresses‚ the vein becomes wider and the AVR ratio get decreased. Based on the AVR value disease detection is made and if it is found to be affected then further processing are required for the estimation of the stage of the disease. D.
