An Approximation Method for Fuzzy Fixed-Charge Transportation Problem
In this paper, we develop the fuzzy fixed charge transportation problem when the costs are the fuzzy numbers. The first step it transform into the classical fuzzy transportation problem. The next, we obtain the best approximation fuzzy on the optimal value of the fuzzy fixed-charge transportation problem. This method obtains a lower and upper bounds both on the fuzzy optimal value of the fuzzy ...
متن کاملAn improvement on LSB+ method
The Least Significant Bit (LSB) substitution is an old and simple data hiding method that could almost effortlessly be implemented in spatial or transform domain over any digital media. This method can be attacked by several steganalysis methods, because it detectably changes statistical and perceptual characteristics of the cover signal. A typical method for steganalysis of the LSB substitutio...
متن کاملOn approximation of the fully fuzzy fixed charge transportation problem
In the literature hardly any attention is paid to solving a fuzzy fixed charge transportation problem. In this paper, we consider the fully fixed-charge transportation problem and try to find both the lower and upper bounds on the fuzzy optimal value of such a problem in which all of the parameters are triangular fuzzy numbers. To illustrate the proposed method, a numerical example is presented.
متن کاملControllability via an Approximation Problem
Abstract This paper is concerned with a nonlinear time-discrete dynamical system whose dynamics is described by a system of vector di erence equations involving state and control vector functions. It can be seen as a contribution to the investigation of problems of controllability via the solution of an approximation problem. The motivation comes from an actual interdisciplinary research eld in...
متن کاملAn Improvement on LSB Matching and LSB Matching Revisited Steganography Methods
The aim of the steganography methods is to communicate securely in a completely undetectable manner. LSB Matching and LSB Matching Revisited steganography methods are two general and esiest methods to achieve this aim. Being secured against first order steganalysis methods is the most important feature of these methods. On the other hand, these methods don't consider inter pixel dependency. The...
