Watermarking schemes evaluation Abstract鈥擠igital watermarking has been presented as a solution to copy protection of multimedia objects and dozens of schemes and algorithms have been proposed. Two main problems seriously darken the future of this technology though. Firstly, the large number of attacks and weaknesses which appear as fast as new algorithms are proposed, emphasizes the limits of this technology and in particu-lar the fact that it may not match users expectations. Secondly, the requirements, tools and methodologies to assess the current technologies are almost non-existent. The lack of benchmarking of current algorithms is bla-tant. This confuses rights holders as well as software and hardware manufacturers and prevents them from using the solution appropriate to their needs. Indeed basing long-lived protection schemes on badly tested watermarking technology does not make sense.

Generate Possion Dis. step1:Generate a random number between [0,1] step2:Let u=F(x)=1-[(1/e)x] step3:Slove x=1/F(u) step4:Repeat Step1~Step3 by using different u,you can get x1,x2,x3,...,xn step5:If the first packet was generated at time [0], than the second packet will be generated at time [0+x1],The third packet will be generated at time [0+x1+x2], and so on …. Random-number generation 1.static method random from class Math -Returns doubles in the range 0.0 <= x < 1.0 2.class Random from package java.util -Can produce pseudorandom boolean, byte, float, double, int, long and Gaussian values -Is seeded with the current time of day to generate different sequences of numbers each time the program executes

Login Manager V3.0(LM3.0) is an authentication system which can integrate with any existing website that meets the requirements. LM3.0 provides a gatekeeper where user must be authorized before entering the membership secured areas. Features: 1. Flexibility LM3.0 allows administrator to integrate it with the current unprotected website. This is especially useful if major changes are going to be painful. With LM3.0, you re just one step towards getting the security you needed most. 2. Speed LM3.0 uses PHP and MySQL which enables fast data transactions.

Text mining tries to solve the crisis of information overload by combining techniques from data mining, machine learning, natural language processing, information retrieval, and knowledge management. In addition to providing an in-depth examination of core text mining and link detection algorithms and operations, this book examines advanced pre-processing techniques, knowledge representation considerations, and visualization approaches. Finally, it explores current real-world, mission-critical applications of text mining and link detection in such varied fields as M&A business intelligence, genomics research and counter-terrorism activities.

This code outputs various NMEA strings to a com port. The code was originally used to test naviation programmes. First select the required com port and the required NMEA message string. There is a default starting position but this can be changed to suit just by typing in a new position. Click on the Start button the current position displayed will change according to the speed and heading selected and the selected NMEA string will be output to the com port and will reflect the current position as displayed. There is a text box which is normally not visible. If you change this to visible the relevant NMEA string can be displayed.

The code for this article was written for version 1.0 of the Active Template Library (ATL). The current version of the code (in SieveATL) was built with Visual C++ 6.0 and the ATL provided with that compiler. It may be slightly different than the code shown in the article. The directory SieveMFC contains an MFC version of a component equivalent to the ATL version discussed in the article. It was built with version 5 of the C++ compiler and the MFC version provided with it. The code discussed in the article was later adapted for Hardcore Visual Basic, Second Edition. Comparable Visual Basic versions are discussed in Chapter 10 of the book. Bruce McKinney

Solve the 8-puzzle problem using A * algorithme. Input: Program reads start state and goal state and heuristic (N or S) from EightPuzzle.INP file.0 representing blank. There are 2 Heuristic: 1. N: Number of misplaced tiles 2. S: Sum of Manhattan distance of current location and target location. Format: The first line write type of heuristic (N or S). Next is the status of departing and landing status. Between 2 states of 1 line blank. See examples EightPuzzle.INP
