Reliability and security are quickly becoming users’ biggest concern due to the increasing reliance on computers in all areas of society. Hardware-enforced, fine-grained memory protection can increase the reliability and security of computer systems, but will be adopted only if the protection mechanism does not compromise performance, and if the hardware mechanism can be used easily by existing...

Background: Among the challenges for implementation of Waterborne public transportation (WPT) are difficulties in procuring efficient ferries tailored towards local requirements. Fundamental questions on ferry’s environmental impact, speed and procurement costs linger transport (PTP) mind. Objective: In this paper, a methodology adopting platform architecture is illustrated by modular design ap...

The article describes essential parts of a prototype system for machine aided translation from Norwegian-Bokmal to Norwegian-Nynorsk. The central parts of the system are a bilingual word list, inflection paradigms, phrases, and routines to deal with compound words. There are also synt2ictic and semantic rules, but they can be considered as preliminary. The article also includes a simple compari...

Let R be an associative ring with identity, C(R) be the category of com-plexes of R-modules and Flat(C(R)) be the class of all at complexes of R-modules. We show that the at cotorsion theory (Flat(C(R)); Flat(C(R))−)have enough injectives in C(R). As an application, we prove that for each atcomplex F and each complex Y of R-modules, Exti (F,X)= 0, whenever Ris n-perfect and i > n.

We show that every semi-artinian module which is contained in a direct sum of finitely presented modules in $si[M]$, is weakly co-semisimple if and only if it is regular in $si[M]$. As a consequence, we observe that every semi-artinian ring is regular in the sense of von Neumann if and only if its simple modules are $FP$-injective.

In this paper, we introduce a generalization of Hilbert $C^*$-modules which are pre-Finsler modules, namely, $C^{*}$-semi-inner product spaces. Some properties and results of such spaces are investigated, specially the orthogonality in these spaces will be considered. We then study bounded linear operators on $C^{*}$-semi-inner product spaces.

In this paper, we have studied the vanishing and relative Cohen-Macaulyness of the functor for relative Cohen-Macauly filtered modules with respect to the ideal  (RCMF). We have shown that the for relative Cohen-Macaulay modules holds for any relative Cohen-Macauly module with respect to  with ........

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.

In an earlier work, we gave (additive) categorification of Grassmannian cluster algebras using the category CM(A) Cohen-Macaulay modules for a certain Gorenstein order A. this paper, each tilting object in CM(A), construct compatible pair (B,L) way that is consistent with mutation. This then determines quantum algebra and show that, when comes from rank one summands, (generically) isomorphic to...
