Within the efforts of publishing online digital libraries, we propose in this paper a new model of a collaborative semantic annotation platform of digitized old documents, which is based on using new technologies of the Semantic Web. In our model, annotations associated with a digitized document are realized by a group of annotators interested in its documentary content to accelerate the Semantic Annotation Process. The annotations are expressed as a set of RDF tripks and stored in a data repository as an RDF graph. The data repositories are managed by an annotation server. With this generic structure of annotations, the available documents resources in the library are accessible and exploitable by various Semantic Web Applications using the same protocol and query language SPARQL, in contrast to the `classic libraries' where access to the documentary resources is limited by specialized web services.

Wireless mesh networks (WMNs) offer dependable and scalable solutions for services utilizing large bandwidth. Enhancement in the deployed number of applications based on wireless mesh networks necessitated a corresponding increased demand for higher bandwidth. This paper proposes a framework for effective management of bandwidth in WMNs making use of the concepts of cross layer design and ant colony methods.

The Wireless Mesh Network (WMN) is a highly capable technology that can offer low-cost and easy-deployable network connectivity to both small-size community networks and large-scale metropolitan networks. As a key emerging technology to provide the next generation broadband networking, WMN combines the advantages of both mobile ad hoc network (MANET) and traditional fixed network, attracting significant industrial and academic attentions. We present a new metric for routing in multi-radio, multihop wireless networks. We focus on wireless networks with stationary nodes, such as community wireless networks. The goal of the metric is to choose a high-throughput path between a source and a destination. Our metric assigns weights to individual links based on the Expected Transmission Time (ETT) of a packet over the link. The ETT is a function of the loss rate and the bandwidth of the link.

A optimised speed controller for permanent magnet synchronous motor (PMSM) is investigated in this paper, in which genetic algorithm (GA), direct torque control (DTC) concept, and neural networks space vector modulation (NNSVM) are integrated to achieve high performance. A GA is integrated to optimize the proportional integral (PI) controller. While NNSVM is contributed to reduce more the ripples of mechanical speed and torque of PMSM, like that combination elements of artificial intelligence, proposed control reacts as, ensemble of intelligent human is gathered to solve a mathematical or physical problem in a little time than one of them. Simulation results show that the proposed controller provides high-performance dynamic characteristics and is robust with regard to plant parameter variations. Furthermore, comparing with the other controller, the harmonic ripples is much reduced by the proposed controller.

In this paper we present a novel fully automated scheme for detection of abnormal masses by anatomical segmentation of Breast Region and classification of regions of Interest (ROI). The system consists of three main processing steps, we perform essential pre-processing to remove noise, suppress artifacts and labels, enhance the breast region, extract breast region by the process of segmentation and remove unwanted parts as Pectoral Muscle. After segregating the breast region, we use an Adaptive Segmentation Procedure based on Kmeans Clustering followed by a Merging Regions method. With the obtained Regions of Interest, the extraction of Statistical and Textural Features is done by using gray level co-occurrence matrices (GLCM) and a Decision Tree Classification is performed to isolate normal and abnormal regions in the breast tissue. If any suspicious regions are present, they get accurately highlighted by this algorithm thus helping the radiologists to further investigate these regions. A set of Mini-MIAS mammograms is used to validate the effectiveness of the method. The precision of the method has been verified with the ground truth given in database and has obtained sensitivity as high as 90%. The CAD system proposed is fully autonomous and is able to isolate different types of abnormalities and it shows promising results.

In this paper we present a new classification of object-oriented metrics, in order to facilitate software evaluation. This classification is based on standardized model “ISO 9126” and focuses on design and quality properties. The crux of this work is to make the relationship between sub-characteristics of ISO model and properties of object-oriented design and quality. Thus our purpose is to find a way to evaluate software without neglecting the properties of the object-oriented design such as: abstraction, inheritance, encapsulation etc.

Collaborative filtering algorithm (CF) is a personalized recommendation algorithm that is the most widely used in e-commerce. In the process of collaborative filtering recommendation, the most used information is the item rating. Item attribute information and other criteria of item evaluation are rarely used. In this paper, a collaborative filtering algorithm based on collaboration between rating item and item information is proposed. The objective is to consider, not only item rating information when we calculate similarity, but also the integration of the background of the item and the time-weight as criteria of the item assessment. In so doing, the calculation of the similarity between items, forming the neighborhood of item, performs the recommendation. This proposed CF algorithm is showing to avoid the problem of sparsity, and also reduces the influence of the former evaluation of the item.

Nowadays, with the evolution of the mobile devices towards a multimode architecture, the users have the opportunity to utilize a wealth of services across a multitude of radio access technologies (RAT's). Variety of vertical handoff algorithms (VHA) have been proposed to help the user to select dynamically the best access network (BAN) in terms of quality of service. However, due to nature of VHA which is NP-Hard problem, the objective of this paper is to provide an optimal network selection algorithm that allow mobile users to choose the BAN with seamless manner. The optimized algorithm exploits a minimum of criteria and combines two multi attribute decision making (MADM) methods such as analytic network process (ANP) method to find the weights of the available networks, and the the grey relational analysis (GRA) method to rank the alternatives. Simulation results are presented to evaluate our optimized network selection decision.

Game theoretic analysis is employed in `medium access control (MAC)' protocol systems for wireless data networks, where the Erasure coding is integrated to improve the reliability and the throughput level. The redundancy is thus introduced, and when it is structured in an exploitable manner, it will be then possible to correct important errors injected by the channel. We present a redundant packets control game to study the behavior of the network performances such the throughput and the cost of coding. A non-cooperative game model is introduced and its different characteristics are defined. We examine the network equilibrium by applying the Nash Equilibrium theorems, and we finish by evaluate our results by appropriate simulations and comparisons with those founded in the conventional model.

Sharing data between autonomous and possibly heterogeneous decentralized systems on the Web gave rise to the concept of P2P database systems. In this paper, we propose a deadlock managing process for distributed and replicated database in P2P based on quorum system. This process is fully decentralized because each client decides if it has the priority to write access.
