  • The discrete wavelet transform (DWT) algorithms have a firm position in processing of signals in several areas of research and industry. As DWT provides both octavescale frequency and spatial timing of the analyzed signal, it is constantly used to solve and treat more and more advanced problems. The DWT algorithms were initially based on the compactly supported conjugate quadrature filters (CQFs). However, a drawback in CQFs is due to the nonlinear phase effects such as spatial dislocations in multi-scale analysis.

  • DWTs are constantly used to solve and treat more and more advanced problems. The DWT algorithms were initially based on the compactly supported conjugate quadrature filters (CQFs). However, a drawback in CQFs is due to the nonlinear phase effects such as spatial dislocations in multi-scale analysis. This is avoided in biorthogonal discrete wavelet transform (BDWT) algorithms, where the scaling and wavelet filters are symmetric and linear phase. The biorthogonal filters are usually constructed by a ladder-type network called lifting scheme.

  • USE OF MODERN BLOCK CIPHERS Symmetric-key encipherment can be done using modern block ciphers. Modes of operation have been devised to encipher text of any size employing either DES or AES. 1 USE OF MODERN BLOCK CIPHERS Electronic codebook (ECB) mode Error Propagation A single bit error in transmission can create errors in several in the corresponding block. However, the error does not have any effect on the other blocks.

  • THE recent development of various methods of modulation such as PCM and PPM which exchange bandwidth for signal-to-noise ratio has intensified the interest in a general theory of communication. A basis for such a theory is contained in the important papers of Nyquist1 and Hartley2 on this subject. In the present paper we will extend the theory to include a number of new factors, in particular the effect of noise in the channel, and the savings possible due to the statistical structure of the original message and due to the nature of the final destination of the information....

  • This paper presents a detailed case study of the Clickbot.A botnet. The botnet consisted of over 100,000 machines and ex- hibited some novel characteristics while also taking advantage of some characteristics of existing, well-known botnets. One of the most novel characteristics of the clickbot is that it was built to conduct a low-noise click fraud attack against syndicated search engines. This paper focuses on describing the novel aspects of the Clickbot.A botnet, and describes parts of our experience in in- vestigating it.

  • For many companies, social media use is still viewed as an experiment, where discrete projects are launched, usually by a few individuals in marketing or communications. Some said they limit their activities because they are in a “test” mode and lack resources to do more. Others said the organizations are wary because they perceive dangers in exposure and lack of control of the conversation on the Web. “Social media is a big ocean and we are pulling in a little bay where we are more protected,” said a global partner in a health and benefits consulting company.

  • The fracture toughness of medium density fiberboard (MDF) as a function of crack length was measured. Fracture toughness was determined from force–displacement and crack length data using a new energy analysis procedure that avoids the scatter of prior discrete analysis methods. Because crack lengths were difficult to observe, they were measured using digital image correlation (DIC). The R curves for two different densities of MDF, two thicknesses, and for both in-plane and through-the-thickness cracks all increased linearly with crack length.

  • Linear estimators for discrete and continuous systems were derived in Chapter 4. The combination of functional linearity, quadratic performance criteria, and Gaussian statistics is essential to this development. The resulting optimal estimators are simple in form and powerful in effect. Many dynamic systems and sensors are not absolutely linear, but they are not far from it. Following the considerable success enjoyed by linear estimation methods on linear problems, extensions of these methods were applied to such nonlinear problems....
