With the advent of multimedia, digital signal processing (DSP) of sound has emerged from the shadow of bandwidth-limited speech processing. Today, the main appli- cations of audio DSP are high quality audio coding and the digital generation and manipulation of music signals. They share common research topics including percep- tual measurement Techniques and analysis/synthesis methods. Smaller but nonetheless very important topics are hearing aids using signal processing technology and hardware architectures for digital signal processing of audio. In all these areas the last decade has seen a significant amount of application oriented research.

一篇關(guān)于TCP-Vegas的文獻(xiàn):Vegas is an implementation of TCP that achieves between 37 and 71％ better throughput on the Internet, with onefifth to one-half the losses, as compared to the implementation of TCP in the Reno distribution of BSD Unix. This paper motivates and describes the three key Techniques employed by Vegas, and presents the results of a comprehensive experimental performance study—using both simulations and measurements on the Internet—of the Vegas and Reno implementations of TCP.

Many of the pattern fi nding algorithms such as decision tree, classifi cation rules and clustering Techniques that are frequently used in data mining have been developed in machine learning research community. Frequent pattern and association rule mining is one of the few excep- tions to this tradition. The introduction of this technique boosted data mining research and its impact is tremendous. The algorithm is quite simple and easy to implement. Experimenting with Apriori-like algorithm is the fi rst thing that data miners try to do.

Semantic analysis of multimedia content is an on going research area that has gained a lot of attention over the last few years. Additionally, machine learning Techniques are widely used for multimedia analysis with great success. This work presents a combined approach to semantic adaptation of neural network classifiers in multimedia framework. It is based on a fuzzy reasoning engine which is able to evaluate the outputs and the confidence levels of the neural network classifier, using a knowledge base. Improved image segmentation results are obtained, which are used for adaptation of the network classifier, further increasing its ability to provide accurate classification of the specific content.

Imperfect C++ Practical Solutions for Real-Life Programming C++, although a marvelous language, isn t perfect. Matthew Wilson has been working with it for over a decade, and during that time he has found inherent limitations that require skillful workarounds. In this book, he doesn t just tell you what s wrong with C++, but offers practical Techniques and tools for writing code that s more robust, flexible, efficient, and maintainable. He shows you how to tame C++ s complexity, cut through its vast array of paradigms, take back control over your code--and get far better results.

This paper addresses the subject of SQL Injection in a Microsoft SQL Server/IIS/Active Server Pages environment, but most of the Techniques discussed have equivalents in other database environments. It should be viewed as a "follow up", or perhaps an appendix, to the previous paper, "Advanced SQL Injection". The paper covers in more detail some of the points described in its predecessor, providing examples to clarify areas where the previous paper was perhaps unclear. An effective method for privilege escalation is described that makes use of the openrowset function to scan a network. A novel method for extracting information in the absence of helpful error messages is described the use of time delays as a transmission channel. Finally, a number of miscellaneous observations and useful hints are provided, collated from responses to the original paper, and various conversations around the subject of SQL injection in a SQL Server environment.

"The GRAPHICS GEMS Series" was started in 1990 by Andrew Glassner. The vision and purpose of the Series was - and still is - to provide tips, Techniques, and algorithms for graphics programmers. All of the gems are written by programmers who work in the field and are motivated by a common desire to share interesting ideas and tools with their colleagues. Each volume provides a new set of innovative solutions to a variety of programming problems.
