let $alpha$ be an endomorphism and $delta$ an $alpha$-derivationof a ring $r$.  in this paper we  study the relationship between an$r$-module $m_r$ and the  general polynomial module  $m[x]$ over theskew polynomial ring $r[x;alpha,delta]$. we introduce the notionsof skew-armendariz modules and skew quasi-armendariz modules whichare generalizations of $alpha$-armendariz modules and extend thecla...

Abstract We compute projective dimension of translated simple modules in the regular block Bernstein–Gelfand–Gelfand category $\mathcal{O}$ terms Kazhdan–Lusztig combinatorics. This allows us to determine which projectives can appear at last step a minimal resolution for module, confirming conjecture by Johan Kåhrström. also derive some inequalities, Lusztig’s $\textbf{a}$-function, possible de...

Mobile agents can be seen as a new paradigm for distributed computing. One characteristic of mobile agents is their autonomy and pro-activity. This article present a framework designed on top of PMADE (Platform for Mobile Agent Distribution and Execution) to support our research in this domain. Our framework consists of three modules. The Map Module collects information on the available network...

Using scene analysis as the task, this research focuses on three fundamental problems in neural network systems: (1) limited processing resources, (2) representing schemas, and (3) learning schemas. The rst problem arises because no practical neural network can process all the visual input simultaneously and e ciently. The solution is to process a small amount of the input in parallel, and succ...

Let $R$ be a commutative ring with identity and $M$ be an unitary $R$-module. The intersection graph of an $R$-module $M$, denoted by $Gamma(M)$, is a simple graph whose vertices are all non-trivial submodules of $M$ and two distinct vertices $N_1$ and $N_2$ are adjacent if and only if $N_1cap N_2neq 0$. In this article, we investigate the concept of a planar intersection graph and maximal subm...

| Using object recognition in simple scenes as the task, this research focuses on two fundamental problems in neural network systems: (1) processing large amounts of input with limited resources, and (2) the representation and use of structured knowledge. The rst problem arises because no practical neural network can process all the visual input simultaneously and e ciently. The solution is to ...

Maintaining the main aspects of the algebraic specification language ASF as presented in [Bergstra&al.89] we have extend ASF with the following concepts: While once exported names in ASF must stay visible up to the top the module hierarchy, ASF permits a more sophisticated hiding of signature names. The erroneous merging of distinct structures that occurs when importing different actualizations...

Hands-on practice is an excellent learning medium for students, and we have developed a competition-based module to teach essential hard technical and soft project skills to students in mid-curriculum. Four groups of students were selected to participate in a 150 hour pilot module. The groups were tasked to design and build a wall-climbing robot with hammering ability to identify poorly adhered...

| This paper presents a writer independent system for large vocabulary recognition of on-line handwritten cursive words. The system rst uses a ltering module, based on simple letter features, to quickly reduce a large reference dictionary (lexicon) to a more manageable size; the reduced lexicon is subsequently fed to a recognition module. The recognition module uses a temporal representation of...

Thrombospondin-1 (TSP-1) is known to be subject to three unusual carbohydrate modifications: C-mannosylation, O-fucosylation, and O-glucosylation. We now describe a fourth: O-β-N-acetylglucosaminylation. Previously, O-β-N-acetylglucosamine (O-β-GlcNAc) was found on a threonine in the loop between the fifth and sixth cysteines of the 20(th) epidermal growth factor (EGF)-like module of Drosophila...
