Molodtsov introduced the theory of soft sets, which can be seen as an effective mathematical tool to deal with uncertainties, since it is free from the difficulties that the usual theoretical approaches have troubled. In this paper, we apply the definitions proposed by Ali et al. [M. I. Ali, F. Feng, X. Liu, W. K. Min and M. Shabir, On some new operations in soft set theory, Comput. Math. Appl....

In this paper, the notion of soft Jacobson radical a ring is defined. A relationship between and semisimple established. Some properties have been studied under homomorphism.

Distant soft tissue tumor metastasis isolated in the digit, presenting as a primary esophageal squamous cell carcinoma is considered extremely rare. Herein, we present a rare case of a 44-year-old male patient with squamous cell carcinoma of the esophagus associated with the clinical symptoms of progressive dysphagia and hoarseness in the course of 2 days. During the second course of chemothera...

in this note we introduce the notion of weak mccoy rings as a generalization of mccoy rings, and investigate their properties. also we show that, if is a semi-commutative ring, then is weak mccoy if and only if is weak mccoy.

Molodtsov introduced the concept of soft sets. In this paper, we present the definition of soft N -groups and construct some basic properties by using N -groups and Molodtsov’s definition of soft sets. We introduce the notions of soft N -subgroups, soft N -ideal, N -idealistic soft N -groups and soft N -group homomorphisms. Moreover, the relations between N -idealistic soft N -groups and soft N...

In this study, dynamic behavior of safety mechanism of a mechanical controller is investigated using 3D-FE simulation. This paper is concentrated on controller of a high acceleration projectile. The controller is located in the top of the projectile. Safety mechanism is divided to deformable and rigid parts. Deformable and rigid parts are simulated in Abaqus and Adams commercial soft wares; res...
