    Diabetes Mellitus is a chronic degenerative disease accepted as a worldwide epidemic. The diabetic foot is one of the most fearful complications of diabetic patients and is responsible for fifty percent of non-traumatic lower-extremity amputations in general hospitals. Foot complications in diabetic patients can be prevented, in most of the cases, by submitting patients to continuous foot examinations and to a personal reeducation process. This paper describes an extension of SiSPED, a system to monitor patients with the possibility of developing the diabetic foot. In this extension the system has been entirely redesigned and new technologies are used to improve performance and maintainability. In addition, the rules applied to generate automatically a diagnostic report are updated to follow international guidelines applied in the diabetic foot prevention. The system also allows the correlation of patient data, essential to measure the impact of the methodology for diabetic foot prevention on the assisted population. View full abstract»

    This paper relates the results of a research developed at Federal University of Sergipe (UFS), whose objective was to investigate and evaluate the presence and participation of hospitals in Sergipe on the cyberspace. The research used data form exploratory, quality and quantitative multiple cases. The research allowed determining how much involved hospitals in Sergipe are on the cyberspace and how insignificant the use of available ICT resources was when compared to other economic sectors or countries. It was observed that the sites are mostly used for institutional promotion, when there is a huge range of possibilities to be explored, such online services, appointment scheduling or blogs. Likewise, the issue of accessibility is not considered by hospitals as a necessity and a citizen's right. Our results outlined a gap in order to identify what reasons justify the low participation of the hospitals in cyberspace. View full abstract»

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (542 KB)  

    Currently, users of 4G networks, based on IP protocol, may take advantage of several opportunities for wireless connectivity in a heterogeneous scenario consisting of a range of access technologies. However, to make mobility and service perception transparent and uninterrupted between these networks it is necessary that network selection mechanisms ensure continuity of services during the vertical handover. This article proposes a selection mechanism of a wireless access network based on quality of experience (Quality of Experience - QoE) and on the traffic load of candidate networks. The scenario evaluated consists of WiMAX and Wi-Fi networks. The proposed mechanism envisages the use of IEEE 802.21 - (Media Independent Handover - MIH) to assist in the handover process. Simulation results in ns-2 using video traffic demonstrate the efficacy of the proposal, with 12,5% gain in video quality. View full abstract»

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (344 KB)  

    Nowadays, there is a number of applications that only run on mobile devices. Mobility is a feature required by an increasing number of current applications. Mobile applications are often required to work even in a scenario with frequent disconnections. These environments with intermittent connectivity compose the so-called Intermittently Connected Mobile Networks (ICMN), where long disconnection intervals and opportunistic connections are assumed. Although the main challenge in such networks is the fact of designing efficient routing protocols to deliver messages from a source to a destination, there is no research focused on providing a generic framework to validate the existing routing schemes proposed by researchers. In this paper, we study the possibility of creating a networking technology for volatile network environments where messages can participate in forwarding decisions as they progress across the network.

    Mesh networks are designed with the goal of providing Internet access service in locations with poor cable infrastructure and service offering free wireless networks. However, these networks have not been standardized and many problems are open or inefficient solution, as routing performance. This article proposes a mechanism, MAC-OLSR, to improve packet routing in a mesh network, using the decision support system, MACBETH, together with the pruning system, which improves the selection criterion of routing protocol OLSR (Optimized Link State Routing). To validate this proposal we developed a prototype in the Network Simulator (NS) tested on a scenario based on a real network. View full abstract»

  • aRDF: A plugin to expose RDFa semantic information using Grails

    Page(s): 1 - 8

    For application developers data is the most important resource that can be found in the web, yet access to it is often subjected to barriers that hinder data reuse and interoperability. The semantic web brings with it the promise of a web of data (instead of the current web of documents) that will help to lower some of the barriers developers encounter when trying to gather data from multiple sources. Instead of having to resort to brittle screen-scrapping techniques, if data that is already present in web pages is encased in markup (such as RDFa) that makes it meaning explicit, developers can harvest that data directly and without ambiguities, turning human readable into machine readable data without the need to duplicate data. Since most of today's web development is done using web application frameworks that generate pages dynamically, placing that kind of markup unassisted is not feasible. As such there is the need for tools that extend the functionalities provided by web application frameworks in order to be able to add that kind of markup to a dynamically generated page, using the correct information for each item. In this paper we introduce one of those tools, aRDF, a plugin for the Grails web application framework that can be used to generate RDFa enhanced pages based on annotated underlying domain information.

    This study presents a set of statistical indexes which allow quantifying the quantity of information contained in physiological signals and its classification for better diagnosis. The physiological signals to considering are constituted by records of microelectrode (MER) obtained during deep brain stimulation (DBS) in parkinsonians patients. The MER corresponds to the subcorticals structures: Thalamus nucleus, Zone Incerta, Subthalamic nucleus and Substantia Nigra. The results show that by means of the statistical indexes obtained it is achieved to locate the different subcorticals structures and using as classifier the algorithm C4.5 of decision trees, is obtained a classification of 98.8 % between the structures. In conclusion, in view of the high precision obtained in the classification, the application of this type of statistical indexes could be used in the process of localization and classification of subcorticals structures, and mainly the subthalamic nucleus for neurostimulation.

    Metric selection in software engineering could be a cumbersome and time-consuming task, and in particular, for web information system due to its inherent immediacy characteristics. Hence, a specific tool for web systems, based on a well-grounded model, is greatly needed. In this paper, we propose a model to address the challenge of metric selection for web systems, and illustrate WDMES (Web Development Measurement Expert System) which has been developed based on this model. We've examined our model by performing a statistical hypothesis testing on the empirical results from web developers. View full abstract»

  • A multi-agent system for obtaining dynamic origin/destination matrices on intelligent road networks

    Page(s): 1 - 8

    Dynamic Origin/Destination matrices are one of the most important parameters for efficient and effective transportation system management. These matrices describe the vehicle flow between different points inside a region of interest for a given period of time. Usually, dynamic O/D matrices are estimated from link traffic counts, home interview and/or license plate surveys. Unfortunately, estimation methods take O/D flows as time invariant for a certain number of intervals of time, which cannot be suitable for some traffic applications. However, the advent of information and communication technologies (e.g., vehicle-to-infrastructure dedicated short range communications - V2I) to the transportation system domain has opened new data sources for computing O/D matrices. Taking the advantages of this technology, we propose in this paper a multi-agent system that computes the instantaneous and dynamic O/D matrix of any road network equipped with V2I technology for every time period and day in real-time. The implementation was done using JADE platform. The results show that the multi-agent system is able to obtain the instantaneous O/D matrix for any time period and day. View full abstract»

    The main goal of this paper is to describe the basic functionalities of the MRTP (Multi-Topology Recovery Protocol) which is a network protocol that provides protection and a fast recovery mechanism, recovering at few milliseconds, for node and link failure in structured mesh networks using pre-processing and multi-topology approach. The protocol was designed considering the state-of-the-art recovery and protection techniques, which will be briefly described throughout this document. One of those techniques, called Resilience Routing Layer, is used as the basic algorithm for sub-topology generation. The protocol prototype was tested in a real environment based on virtualization. The experimentation shows that the protocol leads the network to a quick convergence, below few milliseconds, which presents a sensitive improvement in recovery time, if compared to the currently used protocols such as OSPF, RIP and EIRGP. MTRP produces new recovery paths with costs almost as low as the primary ones with the recovery time practically the hardware failure detection time. View full abstract»
