Importance of estimating the centrality of the nodes in large networks has recently attracted increased interest. Betweenness is one of the most important centrality indices, which basically counts the number of shortest paths going through a node. Betweenness has been used in diverse applications such as social network analysis or route planning. In this paper we find a formula to obtain the betweeness-centrality for grids.

SMEs represent the backbone of most economics. Romanian economy is no exception. Their status represents a signal for the political decision-makers of the actual situation of the economy, because a powerful SMEs sector means a healthy economy. This paper presents the main economic results for SMEs in Romania, considering SMEs' performances in 2007 compared to 2006. The research has been conducted on a sample of 1256 SMEs - micro, small and medium sized enterprises - operating in all economic sectors, covering every age category and each of the eight development regions, being considered as representative for the goals of the research and for the Romanian SMEs' situation.

The rapid development of computer assisted language learning (CALL) has exerted a highly significant influence on college English teaching and learning. This paper intends to explore a brand new listening teaching model-Interactive Self-Access Listening (ISL) teaching model in MCALL (Multimedia CALL) environment and test its effectiveness in practical teaching implementation. After the quantitative data-collection and analysis, a conclusion is reached that most of the students show positive attitudes towards ISL and this model is effective to a large degree in the process of listening.

Following the development of computer science and database technology, distributed data stream processing system becomes a hot research field. In this paper, a distributed multiple data streams join query algorithm DMS-Join is proposed. DMS-Join algorithm can be used on window based data stream model. By rearranging sub join queries and locating them on various nodes, it can decrease the data transportation efficiently. The experiment results show that the algorithm is effective.

This paper presents the development of a piano-playing robot in order to provide people a mean of entertainment. The design and development of this research include two parts: the design of a dexterous hand for manipulating a piano and a linear motion control system. The paper first discussed the design of dexterous hand, and a CAD model is created to examine the feasibility of the hand. Then, a motion control solution was determined, a linear railing along with a rack and pinion gear are applied to produce the linear motion. Finally, a flow chart of the control system was presented. Experimental results show the piano robot can play designated notes.

development and implementing robust IT governance is a basic requirement for a majority of modern organizations. Peterson's IT governance model is establishing itself as an effective model to set up IT governance that will help IT departments adopt themselves with technological partners of businesses. But in this paper we analyze ITUP* which is bases upon ITIL¿ V3, as a model for IT governance, using as a reference IT governance model, other than Peterson model.

The Agile Method known as Scrum has been widely adopted in many companies due to its ability to handle scope changes and produce tangible deliverables at a fast rate. This article presents some limitations of Agile Methods and the results of using Scrum in a specific project. It was found that good practice in development of human computer interfaces have been left aside in favor of reducing sprint duration. The developers almost always "listen to what customers say instead of watch what customers do." This behavior has a tendency to negatively impact usability. This article proposes an Expert System to help developers design Human-computer Interfaces.
