Abstract

Let M be an R-module and N Î s[M]. A projective module P with a superfluous epimorphism p : P ® N is called projective cover of N in s[M]. Even if there are enough projective module in s[M], a module need not have a projective cover. To get projective cover, we need supplement which do not always exist. In this paper, we will investigate relation between supplement of a module M and existence projective cover of a factor module of M.

Abstract

As well known that the model reduction for large-scale linear dynamical systems based on Krylov subspace is called moments matching. In this method, one or more interpolation points is needed to construct  a certain Krylov subspace. In this paper, we propose the proof of theorem for moment matching at Markov parameter using the theorem which is obtained from standard block Arnoldi algorithm.

Abstract

A singular matrix A with size  has a inverse be called Drazin inverse and denoted by . This inverse can be obtained by specifying a generalized Modal matrix and Jordan canonical form  of matrix A. Generalized Modal matrix  is a matrix where its columns consisting of generalized eigen vectors  from the matrix A, while the Jordan canonical form  is a matrix which entries on its main diagonal consisting of Jordan block matrix . Next, two matrices were used to determine Drazin inverse of matrix A.

Abstract

Fuzzy graph is a graph which is consists of a pairs of vertex and edge that have degree contained on closed interval of real number [0,1] on each edge and vertex. Product fuzzy graph was defined by Dr. V. Ramaswamy and Poornima B by replacing “infimum” in definition of fuzzy graph by “product”. In this paper we study product fuzzy graph complete, in connection  complement of produk fuzzy graph, join of produk fuzzy graph and multiplication of produk fuzzy graph. We show that complement of the multiplication of two product fuzzy graphs complete is a multiplication of its complement, in which this disposition produces nil graph.

Abstract

This research paper will present an existing application and the opportunity m-government services base on mobile technology applications. First we examine the existing applications in mobile technology that can be used for m-government services around world. Secondly, we will look at the benefit and disadvantages those mobile technology applications for m-government services. In addition, it will provide an overview the development of ICT in Indonesia and recognizing the particular challenges that exist for e-government in Indonesia. Then, we will create an analysis as the citizen centered models for m-government base on smart phone mobile technology application.
