Montgomery modular multiplication is one of the fundamental operations used in cryptographicalgorithms, such as RSA andElliptic Curve Cryptosystem. The previous Montgomery multipliers perform a single Montgomery multiplication in approximately 2n clock cycles and it requires more numberof addition stages for large word length addition, where nis the size of of operandsoperands inbits. Inthis pa...

Inthis paper, a novel robust medical images watermarking scheme is proposed. In traditional methods, the added watermark may alter the host medical image in an irreversible manner and may mask subtle details. Consequently, we propose a method for medical image copyright protection that may remedy this problem by embedding the watermark without modifying the original host image. The proposed met...

In recent times, several extensions f data mining methods and techniques have been explored aiming at dealing with advanced databases. Many promising applications of inductive logic programming (ILP) to knowledge discovery in databases have also emerged inorder to benefit from semantics andinference rules of first-order logic. Inthis paper, an ILP framework forfrequent pattern discovery in spat...

Inthis paper, -we considersthe linear quadratic optimal control 4, problem on infinite time interval for linear time-invariant systems defined on Hilbert spaces. The optimal control is given by a feedback form in terms of solution r1 to the associated algebraic Riccati equation (ARE). A Ritz type approximation is used to obtain a sequence rl of finite dimensional approximations of the solution ...

We use a gauge fixing for the Rarita-Schwinger equations for helicity 3/2 fields in curved space that leads to a straightforward Hilbert space framework for their study and prove global existence and uniqueness of solutions to the Rarita-Schwinger evolution equations compatible with the constraints inthis framework. We discuss how these results might be applied to the global analysis of the ful...

in many active noise control (anc) applications, an online secondary pathmodelling method that uses a white noise as a training signal is required. this paperproposes a new feedback anc system. here we modified both the fxlms and thevss-lms algorithms to raised noise attenuation and modelling accuracy for theoverall system. the proposed algorithm stops injection of the white noise at theoptimum...

Wepresent a systemfor verifyingthe timing speci cations of digital interfaces. The systemis based on a static analysis of the temporal protocols on the control signals whichmake up the interface. Veri cationis performedbycheckingthat nocausal chainof events onthe control signals violates any of the protocol constraints on those same signals. While the systemdoes not performanychecking of functi...

Let $D=(V,A)$ be a finite simple directed graph. A function$f:Vlongrightarrow {-1,0,1}$ is called a twin minus dominatingfunction (TMDF) if $f(N^-[v])ge 1$ and $f(N^+[v])ge 1$ for eachvertex $vin V$. The twin minus domination number of $D$ is$gamma_{-}^*(D)=min{w(f)mid f mbox{ is a TMDF of } D}$. Inthis paper, we initiate the study of twin minus domination numbersin digraphs and present some lo...

In the first section we give a very short survey on current research on web-based ucational systems and related problems. Inthe second section we argue that knowledge r presentation and ontologies may offer solutions to basic problems inthis area. Since a wellfounded system of concepts, i.e. an ontology, will significantly advance knowledge sharing and interoperability. This will enable both th...
