learning English The following appeared in a memorandum written by the vice president of Nature s Way, a chain of stores selling health food and other health-related products. "Previous experience has shown that our stores are most profitable in areas where residents are highly concerned with leading healthy lives. We should therefore build our next new store in Plainsville, which has many such residents. Plainsville merchants report that sales of running shoes and exercise clothing are at all-time highs. The local health club, which nearly closed five years ago due to lack of business, has more members than ever, and the weight training and aerobics classes are always full. We can even anticipate a new generation of customers: Plainsville s schoolchildren are required to participate in a fitness for life program, which emphasizes the benefits of regular exercise at an early age.

In this project we analyze and design the minimum mean-square error (MMSE) multiuser receiver for uniformly quantized synchronous code division multiple access (CDMA) signals in additive white Gaussian noise (AWGN) channels.This project is mainly based on the representation of uniform quantizer by gain plus additive noise model. Based on this model, we derive the weight vector and the output signal-to-interference ratio (SIR) of the MMSE receiver. The effects of quantization on the MMSE receiver performance is characterized in a single parameter named 鈥漞quivalent noise variance鈥? The optimal quantizer stepsize which maximizes the MMSE receiver output SNR is also determined.

LwIP是瑞士計算機(jī)科學(xué)院(Swedish Institute of Computer Science)的AdamDunkels等開發(fā)的一套用于嵌入式系統(tǒng)的開放源代碼TCP/IP協(xié)議棧。LwIP的含義是Light Weight(輕型)IP協(xié)議。LwIP可以移植到操作系統(tǒng)上，也可以在無操作系統(tǒng)的情況下獨(dú)立運(yùn)行。LwIP協(xié)議的基礎(chǔ)是在減少對硬件資源占用的前提下完成TCP/IP協(xié)議的主要功能

Traveling Salesperson Problem Our branch-and-strategy splits a branch and bound solution into two groups: one group including a particular arc and the other excluding this arc. 1.Each splitting incurs a lower bound and we shall traverse the searching tree with the "lower" lower bound. 2.If a constant subtracted from any row or any column of the cost matrix, an optimal solution does not change.

Playfair Cipher 1.not even the large number of keys in a monoalphabetic cipher provides security 2.one approach to improving security was to encrypt multiple letters 3.the Playfair Cipher is an example 4.invented by Charles Wheatstone in 1854,but named after his friend Baron Playfair Playfair Key Matrix 1.a 5X5 matrix of letters based on a keyword 2.fill in letters of keyword (sans duplicates) 3.fill rest of matrix with other letters Encrypting and Decrypting -plaintext is encrypted two letters at a time 1. if a pair is a repeated letter, insert filler like X’ 2. if both letters fall in the same row, replace each with letter to right (wrapping back to start from end) 3. if both letters fall in the same column, replace each with the letter below it (again wrapping to top from bottom) 4. otherwise each letter is replaced by the letter in the same row and in the column of the other letter of the pair

The code performs a number (ITERS) of iterations of the Bailey s 6-step FFT algorithm (following the ideas in the CMU Task parallel suite). 1.- Generates an input signal vector (dgen) with size n=n1xn2 stored in row major order In this code the size of the input signal is NN=NxN (n=NN, n1=n2=N) 2.- Transpose (tpose) A to have it stored in column major order 3.- Perform independent FFTs on the rows (cffts) 4.- Scale each element of the resulting array by a factor of w[n]**(p*q) 5.- Transpose (tpose) to prepair it for the next step 6.- Perform independent FFTs on the rows (cffts) 7.- Transpose the resulting matrix The code requires nested Parallelism.

QuickSteps books are recipe books for computer users. They answer the question 揌ow do I...??by providing a quick set of steps to accomplish the most common tasks with a particular program. The sets of steps are the central focus of the book. Sidebar QuickSteps provide information on how to do quickly many small functions or tasks that are in support of the primary functions. Sidebar QuickFacts supply information that you need to know about a subject. Notes, Tips, and Cautions augment the steps, but they are presented in a separate column to not interrupt the fl ow. Brief introductions are present, but there is minimal narrative otherwise. Many illustrations and fi gures, a number with callouts, are also included where they support the steps.

NN Functions a program in Lisp to demonstrate working of an artificial neuron. (Enter an input vector X and weight vector W. Calculate weighted sum XW. Transform this using signal or activation functions like logistic, threshold, hyperbolic-tangent, linear, exponential, sigmoid or some other functions (syntax provided) and display the output).
