Journal Title: INTERNATIONAL JOURNAL OF MATHEMATICS TRENDS AND TECHNOLOGY - Year 2013, Vol 4, Issue 2
Abstract
Relational Algebra is that branch of algebra which deals about set operations on a given relation such as UNION,INTERSECTION,DIFFERENCE,CARTESIAN PRODUCT, PROJECTION ,SELECTION. In this paper we shall discuss these operations in terms of SQL(STRUCTURED QUERY LANGUAGE).

AN APPLICATION OF FUZZY SOFT RELATION IN DECISION MAKING PROBLEMS
Here we present the concept of soft relations and fuzzy soft relations and then applied in a decision making problem. In approximate reasoning, fuzzy soft relations have shown to be of a primordial importance. Huma...
Solving Fuzzy Two-Stage Programming Problem with Discrete Fuzzy Vector
The fuzzy two-stage programming problem with discrete fuzzy vector is hard to solve. In this paper, in order to solve this class of model, we design a algorithm by which we solve its deterministic equivalent programming...
Bootstrap Testing for Long Range Dependence
The presence of long-memory or long-range dependence (LRD) in a stochastic process has important consequences in statistical inferences. Lo develops a robust test for detecting the existence of LRD and derives its asympt...
