A vague soft set is a mapping from a parameter set to the collection of vague subsets of the universal set. In this study, a vague soft relation is presented based on the Cartesian product of vague soft sets. The basic properties of these relations are studied to explain the concept of transitive closure of a vague soft relation. The symmetric, reflexive, and transitive closures of a vague soft set are introduced followed by examples to illustrate these relations. The concepts are further extended by proposing some of their properties. The existence and uniqueness of the transitive closure of a vague soft relation are established, and an algorithm to compute the transitive closure of a vague soft relation is also provided.

A three-dimensional micro-mechanical model for predicting the compressive strength of composite laminates is presented in this paper. The effect of initial misalignment of fiber angle on the compressive strength of fibrous composites is investigated. The compressive strength of fibrous composites is estimated using the actual initial misalignment of fibers in the rotated plane. The initial misalignment angles in both directions are defined as a curve in the form of a cosine function. Equilibrium equations are then derived for a Representative Volume Element (RVE) along the axis of the fibers using total potential energy principle. Minimization of the total potential energy with respect to the amplitudes defined by the initial waviness function of the fibers yields a formula used to define the maximum compressive strength of fibrous composite materials. The formula obtained in this paper is used to study continuous fiber/polymer matrix composites. The results obtained by the model presented in this paper are in a good agreement with experimental data obtained from compression tests on [±60ο/0ο] specimens and theoretical results available in the literature.

The aim of this work is to introduce for the first time the concept of D-set. This is done by defining a special type of cover called a D-cover. we present some results to study the properties of D-compact spaces and their relations with other topological spaces. Several examples are discussed to illustrate and support our main results. Our results extend and generalized many will known results in the literature.
