Introduction No Unix"class system administrator or user will get far without learning the basics of vi#1$, the widespread visual text"mode editor. Contrary to some misinformed opinions spread among users who are new to Unix"class systems, vi#1$ is n
CVS (Concurrent Versions System) is a tool that enables you to track changes to a set of files over time. CVS is commonly used in software development to allow multiple developers to coordinate changes, track versions, and permit simultaneous develo
In several cryptographic systems, a fixed element g of a group of order N is repeatedly raised to many diff erent powers. In this paper we present a practical method of speeding up such systems, using precomputed values to reduce the number of multi
The testing of software plays a very important role in the process of its development, since potentially every new piece of software contains bugs. Some of the bugs are just simple mistakes, like typos or omissions, that can be spotted quite easily
This documents describes the features and non-features of di erent C preprocessors, compilers, and environments. As such, it is an incomplete document, growing as information is gathered. It contains some material concerning ANSI C but it is not a s
An Introduction to Wavelets IEEE Wavelets are mathematical functions that cut up data into di erent frequency components, and then study each component with a resolution matched to its scale. They have advantages over traditional Fourier methods in
A cellular automaton is a decentralized computing model providing an excellent platform for performing complex computation with the help of only local information. Researchers, scientists and practitioners from di erent elds have exploited the CA pa
The ability to adapt to different computing environments or external changes is an important requirement for both stationary and mobile computing. Without this ability, all requirements have to be foreseen, which is often not possible in practice. Cl
关于换热器动态建模仿真的研究文章 摘要如下： This work presents the mathematical modelling and simulation of complex plate heat exchanger arrangements under milk fouling, using detailed dynamic models. A complex fouling model based on a reaction/mass transfer scheme is c
This paper presents an overview of recent progress in the area of multiple-input multiple-output (MIMO) space-time coded wireless systems. After some background on the research leading to the discovery of the enormous potential of MIMO wireless link
We have designed and implemented the Google File Sys- tem, a scalable distributed file system for large distributed data-intensive applications. It provides fault tolerance while running on inexpensive commodity hardware, and it delivers high aggrega
高清PDF文件 Preface Most every mathematics Ph.D. student must take a qualifying exam in com- plex variables. The task is a bit daunting. This is one of the oldest areas in mathematics, it is beautiful and compelling, and there is a plethora of material.
We consider the problem of discovering association rules between items in a large database of sales transactions. We present two new algorithms for solving this problem that are fundamentally di erent from the known algo- rithms.
一篇写得很清晰的论文，希望看了会有帮助 The physics of compressive sensing (CS) and the gradient-based recovery algorithms are presented. First, the di®erent forms for CS are summarized. Second, the physical meanings of coherence and measurement are given. Third, the g
Abstract—This paper presents a novel direct digital frequency synthesis (DDFS) ROM compression technique based on two properties of a sine function: (a) piecewise linear technique to approximate a sinusoid, and (b) variation in the slope of the sinu
There was a deep depression in the early 1990s in Finland, during which the number of jobs in Finnish industry decreased. By improving productivity, we can increase the price competitiveness of Finnish products and create the necessary conditions fo
The management of data in telecommunications system has many aspects whereof some, but not all, are addressed by traditional commercial DBMSs Data Base Management Systems . In particular the very high level of fault tolerance which is required in m
