in this paper, we show that every element of a discrete module is a sum of two units if and only if its endomorphism ring has no factor ring isomorphic to $z_{2}$. we also characterize unit sum number equal to two for the endomorphism ring of quasi-discrete modules with finite exchange property.

in this paper we introduce the concept of dirac structures on (hermitian) modules and vectorbundles and deduce some of their properties. among other things we prove that there is a one to onecorrespondence between the set of all dirac structures on a (hermitian) module and the group of allautomorphisms of the module. this correspondence enables us to represent dirac structures on (hermitian)mod...

The present paper presents a system used for performing design by making extended use of soft computing techniques. Throughout the paper the design of robotic grippers for flexible materials is used as a reference design case in both its conceptual and detailed design phases. The system contains three modules. The first module focuses on the conceptual design phase and is used for: a. the gener...

Let  be a commutative ring and  be a unitary  module. We define a semi prime sub module of a module and consider various properties of it. Also we define semi-radical of a sub module of a module and give a number of its properties. We define modules which satisfy the semi-radical formula and present the existence of such a module.

Soft biometric traits like gender, age, height, weight, ethnicity, and eye color cannot provide reliable user recognition because they are not distinctive and permanent. However, such ancillary information can complement the identity information provided by the primary biometric traits (face, fingerprint, hand-geometry, iris, etc.). This paper describes a hybrid biometric system that uses face ...

We present Galinha, a system that integrates multiple linguistic resources and tools. Galinha enables easy module integration and testing of prototypical configurations, thereby reducing the effort and backtracking usual in the construction of modular applications. Moreover, it has a soft learning curve, enabling new users and developers to use it successfully.

All rings are commutative with 1 6= 0, and all modules are unital. The purpose of this paper is to investigate the concept of 2-absorbing primary submodules generalizing 2-absorbing primary ideals of rings. Let M be an R-module. A proper submodule N of an R-module M is called a 2-absorbing primary submodule of M if whenever a, b ∈ R and m ∈M and abm ∈ N , then am ∈M -rad(N) or bm ∈M -rad(N) or ...

We have presented a multi-level adaptive hierarchical scheduling framework in our previous work. The framework targets compositional real-time systems which are composed of both hard and soft real-time systems. While static CPU portions are reserved for hard real-time components, the CPU portions of soft real-time components are adjusted during run-time. In this paper, we present the implementa...

Design parameters Abstract In rhis paper: we propose a Soft lP Generator which can add or remove PCM Codec modules arbitrarily. It can be applied ro PCM Codec IP designs rhat need to change their related modules corresponding to different working environments. It also can help us to easily manage our Soft IP modules, produce optimized modules, and remove unnecessary modules, in order ro reduce ...
