Texto completoPrecise Point Positioning (PPP) allows for accurate Global Navigation Satellite System (GNSS) based positioning without the immediate need for observations collected by regional station networks. The fundamental drawback of PPP in comparison to differential techniques such as Real-Time Kinematic (RTK) is a significant increase in convergence time. Among a plurality of different measures aiming for a reduction of convergence time, fixing the estimated carrier phase ambiguities to integer values is the key technique for success. The ambiguity resolution asks for a robust functional model and rests upon a two-stage method ruling out first-order ionospheric effects. In this context the Melbourne-Wübbena linear combination of dual-frequency carrier phase and code measurements leverages a simple resolution of widelane ambiguities. As a consequence the in comparison to the wavelength of the ionosphere-free linear combination significantly longer narrowlane wavelength can be used to form the ionosphere-free linear combination. By default the applied functional model is solely based on observations of the Global Positioning System (GPS). However measurements from the GLObal’naya NAvigatsioannaya Sputnikovaya Sistema (GLONASS) can contribute to improve the model’s stability significantly. Due to the technique used by GLONASS to distinguish individual satellites (Frequency Division Multiple Access, FDMA), the signals broadcast by those satellites differ in their frequencies. The resulting slightly different frequencies constitute a barricade for both modelling and correcting any device-dependent signal delays, e.g. fractional-cycle biases (FCB). These facts limit the applicability of the conventional ambiguity-fixing approach when it comes to GLONASS signals. The present work puts a focus both on investigating the device-dependent GLONASS signal delays and on developing an alternative method for fixing GLONASS ambiguities with the ultimate objective of a combined GPS/GLONASS ambiguity resolution. The alternative ambiguity resolution strategy is based on the pure widelane linear combination, for which reason ionospheric corrections are indispensable. The procedure is applicable for GLONASS in the first instance but reveals equivalent results for both GPS and GLONASS. The disadvantage relative to the conventional approach is the reduced ambiguity fixing success rate

Texto completoA TV Digital Interativa traz consigo uma série de mudanças que vai muito além da melhoria de qualidade em áudio e vídeo. Ela trará o aumento da diversidade e disponibilidade de conteúdo multimídia e fará com que as pessoas deixem de ser meros espectadores para se tornarem também usuários de aplicativos multimídia interativos. Estes aplicativos virão com o conteúdo multimídia e irão permitir que o usuário possa interagir ativamente com o conteúdo exibido ou até mesmo com as emissoras, pois os padrões de TV digital prevêem a existência de um canal de interação através do qual o aparelho de TV possa se comunicar numa rede de computadores, como a Internet, por exemplo. Desta forma, as aplicações de TV digital poderão acessar serviços como e-mail, Internet-banking e comércio eletrônico. No entanto, estes são serviços centralizados e não exploram a interatividade entre as pessoas. É fácil prever que, num futuro próximo, existirá demanda por aplicações que explorem a interatividade entre as pessoas. Porém, fazer com que estas aplicações se comuniquem é um verdadeiro desafio, pois o uso de servidores para intermediar mensagens está sujeito a problemas de escalabilidade, e a troca direta de mensagens é prejudicada pela heterogeneidade da rede em que o canal de interação é disponibilizado. Este trabalho propõe um Middleware para este tipo de aplicação distribuída. O Middleware proposto foi baseado no modelo de comunicação peer-to-peer, pois, após a análise dos requisitos deste tipo de software distribuído, verificou-se que este modelo é o que melhor se adequa. O mesmo foi construído sobre a plataforma JXTA, que resolve os problemas de infra-estrutura da rede, compreendendo um serviço avançado de busca e um mecanismo de invocação remota de método, semelhante à tecnologia Java RMI

Texto completoDie Auslegung von Wasserkraftanlagen stellt einen komplexen Planungsablauf dar, mit dem Ziel das vorhandene Wasserkraftpotential möglichst vollständig zu nutzen und künftige, wirtschaftliche Erträge der Kraftanlage zu maximieren. Um dies zu erreichen und gleichzeitig die Genehmigungsfähigkeit eines komplexen Wasserkraftprojektes zu gewährleisten, besteht hierbei die zwingende Notwendigkeit eine Vielzahl für die Konzepterstellung relevanter Einflussfaktoren zu erfassen und in der Projektplanungsphase hinreichend zu berücksichtigen. In frühen Planungsstadien kann ein Großteil der für die Detailplanung entscheidenden, technischen und wirtschaftlichen Parameter meist nicht exakt bestimmt werden, wodurch maßgebende Designparameter der Wasserkraftanlage, wie Durchfluss und Fallhöhe, einen umfangreichen Optimierungsprozess durchlaufen müssen.

Recently, peer-to-peer (P2P) botnets have been adopted for a variety of cyber-crimes. Many approaches for P2P botnet detections had studied, but most of them are based on a single domain traffic to analyze bot activities. It seems hard to recognize the malicious activities from a single domain traffic, especially for P2P botnets that often scattered across the Internet to exchange information. In this paper, we propose an innovative P2P botnet detection algorithm to federate multiple sites to inter-domain traffic analysis. Our algorithm first extracts traffic as feature vectors, and then run a cooperative graph-based algorithm across multiple domains to improve precision. We believe our P2P botnet detection can solve well-known and unknown botnets. Evaluation based on real traffic journal shows the availability of our approach, and the verification was given using VirusTotal to validate the outcomes correctness which at least 80 percentage malicious IPs appeared on it.

With the rapidly increasing bandwidth at the access link of end users, more and more users nowadays tend to select and enjoy their desired videos directly from VoD servers. How to efficiently provide on-demand media streaming services has emerged as an important issue deserving serious attention. In this paper, based on the Loopback-MDC architecture, we propose an Inter-Description failure recovery mechanism and ExtLoopback-MDC architecture. Inter-Description failure recovery is proposed to reduce the additional workload imposed on the proxy server due to clients’ early departures. ExtLoopback-MDC architecture is proposed to reduce the additional workload imposed on the proxy server due to the low peer arrival rate. The proposed Inter-Description failure recovery mechanism includes peer buffer management and inter-description recovery. Both the robustness and availability of video streams are taken into account in the design of the proposed Inter-Description failure recovery mechanism so as to boost the scalability of proxy servers, lessen the impact of peers’ early departure on others and provide users with better QoS. When the resilience and availability of certain videos in the Loopback-MDC architecture is low, ExtLoopback-MDC architecture can improve the resilience of the proxy server and enhance the peers’ waiting time, thereby providing users with better QoS. The simulation results show that the Inter-Description failure recovery mechanism can efficiently deal with peers’ early departures and reduce the bandwidth consumption required for the proxy server to recover peers abandoned by departing ones. The simulation results also show that the Inter-Description failure recovery mechanism can efficiently deal with the low peer arrival rate for the proxy server to recover peers abandoned by departing ones
