Node failures in Wireless Sensor Networks composed by static sensor nodes are common due to the nature of the sensor devices and the usually harsh environments in which they are deployed. Node failures can diminish the performance of the network as a whole, thus affecting its functionality in delivering the desired services. For instance, significant regions can become uncovered due to failure of several nearby nodes. This paper reports a study about the use of mobile sensor nodes acting in cooperation with static ones in order to fill gaps created by faulty static nodes. The proposed fault handling mechanism presents alternative policies with pros and cons, depending on the user priorities imposed to the system and the occurrence of failures. A discussion about this topic is presented based on results obtained by simulation of the proposed mechanisms. © 2011 IEEE.

When developing component-based software, the compatibility analysis is a necessary step to ensure the interoperability of the connected components. It allows early identification of problems caused by incompatible components. This paper presents the automated process of structural and behavioral compatibility analysis deployed in the SEA environment. From the specification of component-based software, made entirely with UML diagrams, tools are triggered to automatically perform the compatibility analysis. The structural analysis considers component, deployment and class diagrams. The behavioral analysis also treats the state machine diagram, which is transparently converted to a Petri net, that is, the user only handles UML diagrams. Behavioral problems are identified by interpreting Petri net properties for the context of components.

The idea of a Kripke semantics endowed with possibility/plausibility information is not new;in fact there are different approaches for that;see: [6], [13], [16], [19]. This paper follows the approach found in [6], but whereas [6] provides a fixed interpretation for connectives into [0,1] here we provide a characterization of a fuzzy semantics for connectives in such a way that the resulting fuzzy frames: K, T and D, are described precisely by the set of statements which also describes, respectively, the usual modal systems K, T and D. © 2011 IEEE.

Publicly available molecular datasets can be used for independent verification or investigative repurposing, but depends on the presence, consistency and quality of descriptive annotations. Annotation and indexing of molecular datasets using well-defined controlled vocabularies or ontologies enables accurate and systematic data discovery, yet the majority of molecular datasets available through public data repositories lack such annotations. A number of automated annotation methods have been developed;however few systematic evaluations of the quality of annotations supplied by application of these methods have been performed using annotations from standing public data repositories. Here, we compared manually-assigned Medical Subject Heading (MeSH) annotations associated with experiments by data submitters in the PRoteomics IDEntification (PRIDE) proteomics data repository to automated MeSH annotations derived through the National Center for Biomedical Ontology Annotator and National Library of Medicine MetaMap programs. These programs were applied to free-text annotations for experiments in PRIDE. As many submitted datasets were referenced in publications, we used the manually curated MeSH annotations of those linked publications in MEDLINE as "gold standard" Annotator and MetaMap exhibited recall performance 3-fold greater than that of the manual annotations. We connected PRIDE experiments in a network topology according to shared MeSH annotations and found 373 distinct clusters, many of which were found to be biologically coherent by network analysis. The results of this study suggest that both Annotator and MetaMap are capable of annotating public molecular datasets with a quality comparable, and often exceeding, that of the actual data submitters, highlighting a continuous need to improve and apply automated methods to molecular datasets in public data repositories to maximize their value and utility. © 2011 Elsevier Inc.

Errors in diagnosing the disease is a critical risk that must be faced by any person giving treatment to the hospital. Medical treatment can not always be done with perfect accuracy. Lung cancer is one of the most deadly disease that prone to misdiagnose. In general, some practitioners tend to read cancer in x-ray rontgen image as tumor this could be fatal. To generate a diagnose, a general practitioner use three kind of examination i.e : patient History, Radiologic examination, phisical examination. In this paper, Gray color for image indexing and retrieval are investigated. The features are derived based on the statistical distribution of Harralick feature from image sample. By utilizing the proposed invariant features, the similarity measure between query and database images provides reliable retrieval results. © 2010 IEEE.

Nowadays, process management represents a fundamental initiative to provide competitive advantages to organizations. The ability to build and operate such processes can provide competitive advantages to these organizations. In this paper, we present an approach for elicitating and discovering problems in business processes that combines the technique of group storytelling with the theory of constraints. This article suggests that group storytelling allows the collection of knowledge to identify the gaps and deviations that exist in business processes, while the theory of constraints provides a language for representing them. We conducted and reported an experimentation of the proposed method in the petroleum field sampling process, with the support of a groupware tool. © 2010 Springer-Verlag Berlin Heidelberg.

Artificial Immune Systems (AISs) are composed of techniques inspired by immunology. The clonal selection principle ensures the organism adaptation to fight invading antigens by an immune response activated by the binding of antigens and antibodies. As an immune response can be elicited even when the binding between an antigen and an antibody is not perfect, an approximate binding might suffice, and a Fuzzy Logic mechanism might be the most appropriate mechanism to control such process. This paper presents a novel hybrid model based on concepts of Immune and Fuzzy Systems with applications to pattern recognition problems. The preliminary results obtained here suggest the proposed model is a promising pattern recognition tool. © 2010 IEEE.

Collective Intelligence has received much attention in recent years, as organizations and businesses discover the power of crowds. With new technologies, such as blogs, twitter, wikis, photo sharing, collaborative tagging and social networking sites, people may create and disseminate content as never before. Many organizations are looking for ways to harness this power, which is being called collective intelligence. Additionally, many open-source initiatives have shown that it is possible to obtain high quality results from collectively produced work. In this paper, we consider the domain of emergency response. We have been working in this domain for a few years now, mostly focusing on small disaster relief groups and field command. One of the command problems is lack of information about the location where the disaster occurred. We believe some of this information could be crowdsourced, changing current practices and enabling more effective response to the situation. In this paper, we discuss the possibilities for crowdsourcing and present an initial proposal for harnessing collective intelligence for the fire department. © 2010 IEEE.
