In this work we design an approximation algorithm using neighbors, history and errors (NHE algorithm) to analyze and approximate the behavior of sensors readings after it fails. NHE algorithm computes and associates a specific equation to each sensor that has factors computed using neighbors, history data and the approximation error as a feedback factor. In some cases, it is difficult to reach each sensor to read its value either due to a connection problem or the sensor itself is down and not reachable. In those cases, NHE algorithm uses the evaluated equations to approximate this down sensor reading. The results of the experiments using this algorithm prove that it is powerful but with specific constraints.

Recommender systems, as effective approaches to information overload issue, have attracted researcherspsila attention especially in the field of electronic commerce. They provide personalized recommendations on products/services to customers. From a sellerpsilas point of view the process of recommendation is a multi-criteria decision problem. So the recommender systems can also be seen as decision support systems which help a seller to decide and choose suitable items for recommendation. This study proposes a novel design of recommender systems for product recommendation to new users -by collecting both implicit and explicit information- based on the PROMETHEE II methodology which is a well known multi-criteria decision analysis out-ranking method. We also experienced the recommendation from different but relevant sorts of items in this design. The performance of the proposed recommendation algorithm is tested with real world data. Experimental results reveal that the proposed system is feasible and can yield satisfactory recommendations.

The SBVR (semantics of business vocabulary and rules) vocabulary and rules can be represented in different ways like structured English, RuleSpeak business rule notation and ORM Notation etc. These are textual notations and they wonpsilat help in understanding the meaning of a business rule at a glance. In this paper we are proposing a visual notation for SBVR which enables easy comprehension of the rules. We also demonstrate its feasibility and utility by building an editor tool.

Recently, peer-to-peer (P2P) networking has become popular, and is being expected as a content sharing platform for ubiquitous networking. In ubiquitous networking, the notions of location and time are essential. Although some location-based P2P networks have been proposed, they only consider locations, and the notion of time has not been considered. In this paper, we propose P2P searching mechanisms for location-aware contents with time-dependent importance, which enables us to retrieve contents with high importance in time period specified in a query. The proposed mechanisms are based on a location-based P2P network, and each peer establishes additional links to peers within n-hops. Each peer also manages a link table, which records location and time-dependent importance of contents that its linked peers hold. Using the link table, a time-specified query is forwarded selectively to neighboring peers. Simulation results show that the proposed mechanisms enable us to search contents with high relevance while keeping network traffic low.

dasiaContext is keypsila conveys the importance of capturing the digital environment of a knowledge worker. Knowing the userpsilas context offers various possibilities for support, like for example enhancing information delivery or providing work guidance. Hence, user interactions have to be aggregated and mapped to predefined task categories. Without machine learning tools, such an assignment has to be done manually. The identification of suitable machine learning algorithms is necessary in order to ensure accurate and timely classification of the userpsilas context without inducing additional workload. This paper provides a methodology for recording user interactions and an analysis of supervised classification models, feature types and feature selection for automatically detecting the current task and context of a user. Our analysis is based on a real world data set and shows the applicability of machine learning techniques.

This paper presents a flexible question answering system (FQAS) for mobile wireless devices. FQAS comprises a fuzzy logic-based information retrieval (IR) system together with a question answering system that employs information extraction techniques and passage retrieval mechanisms. The IR system includes techniques such as fuzzy term mining and concept clustering. The information extraction module recognizes and extracts relevant information from tables embedded in Web pages at specialized Web sites. The passage retrieval system determines the passage in a document collection that most likely contains the answer to a question. Our current prototype is capable of answering queries and questions within the chosen football (soccer) test domain.

In the engineering curriculum, remote labs are becoming a popular learning tool. The advantages of these laboratories and the different deployments have been analyzed many times, but in this paper we want to show the results of the evaluation of WebLab-Deusto as a learning tool. This work is focused on the subjects programmable logic (PL) in the third year of Automation and Electronics Engineering and in Electronics Design (ED) of the fifth year of the same degree. The paper presents the results of the surveys done by students since 2004. This survey consists of fifteen questions and its main objective is to measure the acceptance, usability and usefulness of the remote laboratory developed at University of Deusto.

A novel genetic algorithm based resource scheduling algorithm is proposed; simulation results show that this algorithm is both feasible and efficient for use in DVPN scenarios.

Scalability, decentralized processing time and power and also eliminating the single point of failure are some of the benefits of using peer to peer systems for management purposes. There has been little effort on formulating or evaluating different important factors of network management in P2P management networks. As an important factor wepsilave focused on availability in network management systems. In this paper, we propose our framework for networks management, formulate availability in this platform. Then we provide an algorithm that helps to increase data availability in P2P management networks.
