A study of Final State Effects (FSE) on the dynamic structure function of superfluid 4 He in the Gersch–Rodriguez formalism is presented. The main ingredients needed in the calculation are the momentum distribution and the semidiagonal two–body density matrix. The influence of these ground state quantities on the FSE is analyzed. A variational form of ρ 2 is used, even though simpler forms turn...

Ensemble learning technique attracted much attention in the past few years. Instead of using a single prediction model, this approach utilizes a number of diverse accurate prediction models to do the job. Many methods have been proposed to build such accurate diverse ensembles, of which bagging and boosting were the most popular. Another method, called Feature Subset Ensembles (FSE), is thoroug...

The Feynman-Smoluchowski Engine (FSE) is simply a ratchet and pawl device, connected by a shaft to a vane, that is small enough to rectify the effect of random bombardment of gas molecules on the vane. The significance of the FSE is that it has inspired much activity in the area of Brownian ratchets. There is considerable interest in both the FSE and Brownian ratchets as these models are findin...

We study the local minima relocation of the fractionally spaced Constant Modulus Algorithm(FSE-CMA) cost function in the presence of noise. Local minima move in a particular direction as the noise power increases and their number may be eventually reduced. In such cases the performance of FSE-CMA may fail to adequately reduce inter symbol interference (ISI), but achieve an approximated MMSE by ...

Folding Applying a set of inverse symmetry operations on a set of points. This procedure is one of the main steps in the folding unfolding method for evaluating the CSM of a set of points. Folding unfolding method A visual and computational procedure for evaluating the CSM of a set of points. Fuzzy subset A set whose elements have a range of values corresponding to the degree of membership in t...

This paper presents a new extension of fuzzy sets: R-fuzzy sets. The membership of an element of a R-fuzzy set is represented as a rough set. This new extension facilitates the representation of an uncertain fuzzy membership with a rough approximation. Based on our definition of R-fuzzy sets and their operations, the relationships between R-fuzzy sets and other fuzzy sets are discussed and some...

In recent years, the Fuzzy Relational Database and its queries have gradually become a new research topic. Fuzzy Structured Query Language (FSQL) is used to retrieve the data from fuzzy database because traditional Structured Query Language (SQL) is inefficient to handling uncertain and vague queries. The proposed model provides the facility for naïve users for retrieving relevant results of no...

Abstract : Fuzzy Logic is based on the idea that in fuzzy sets each element in the set can assume a value from 0 to 1, not only 0 or 1, as in crisp set theory. The degree of membership function is defined as the gradation in the extent to which an element is belonging to the relevant sets. Optimizing the membership functions of a fuzzy system can be viewed as a system identification problem for...
