Using a mathematical model of the knee we have tried to identify which osteosynthesis method is associated with the best clinical outcome and rehabilitation results. This study was secondary to our observation that a deficient osteosynthesis, even a minimal invasive one (MIS) needs to be associated with external fixation procedures and a knee articulation which is immobilized in the cast for more...
This chapter proposes a novel concept towards the deployment of a networked ‘Media Ecosystem’. The proposed solution is based on a flexible cooperation between providers, operators, and end-users, finally enabling every user first to access the offered multimedia services in various contexts, and second to share and deliver his own audiovisual content dynamically, seamlessly, and transparently to...
This study presents the design and prototype development of a time - controlled access system consisting of an Arduino Mega ADK 2560 microcontroller integrated with a PN532 RFID/NFC Shield, Ethernet Shield, LCD, solenoid lock and a control circuit for the loads to address security issues and help save power consumptions of any institutions. When a passive RFID tag is placed in the reading range of...
Patients with liver cirrhosis develop autonomic dysfunction, both viral and alcoholic etiology being associated with autonomic imbalance. Holter monitoring of the electrocardiogram is used to evaluate the autonomic dysfunction of the patient through heart rate variability (HRV) analysis. Thirty-five patients with liver cirrhosis, mean age 61.1±8.17 years and female/male ratio 17/18, and a control...
Mobile Cloud Networks group together mobile users and clouds containing content servers. Hence, they are an ideal framework for media content delivery. Streamswitching adaptive video players cope well with some limitations of Mobile Cloud Networks as low bandwidth and bandwidth variability in access network. Nonetheless, other limitations, as cloud congestion, are difficult to be managed by the video...
Intensive research in the networking domain addresses content- and context-aware features for the Future Internet. Thus, being able to manipulate data flows and to adapt those to given constraints with a minimum resource involvement is a hot topic. On top of this topic, video manipulation is the challenge to undertake in order to optimize resource-consuming processes. However, developing heterogeneous...
Wyprodukowano tkaniny o dobrej przewodności elektrycznej, z włókien bawełnianych o splocie płóciennym, pokrytych roztworem zawierającym cząsteczki sadzy. Przedstawiono wyniki przewodności elektrycznej uzyskane przy stosowaniu roztworów o rożnym składzie i rożnym stężeniu cząstek sadzy. Określono optymalny skład i stężenie cząstek sadzy dla uzyskania praktycznych wyników.
This paper presents a novel user-centric networked-media architecture, where content-aware capabilities at the network layer are intimately tied-up with network-aware functions at the service's layer, towards maximum possible QoS/QoE provision. Focusing on the network segment, the paper initially presents the design of a novel virtual layer on top of the traditional network plane capable to enable...
The Future Internet is foreseen to fully handle multimedia services which have experienced an explosive growth in the recent years. Therefore, improving the scalability of these services is getting crucial. One common approach for this purpose is the deployment of multiple replicas of a server throughout the network. The resulting issue is to direct the user request to the best server. Methods based...
With the important advent of multimedia services and the ubiquity of computing environments, the concept of context-awareness in services access and provisioning is getting crucial. Services, especially the multimedia ones, must perform automatically actions/operations to adapt the delivered content to the user expectations and his environment capabilities, thus ensuring the best quality of experience...
Providing negotiation capability in self-management environments is a challenging area of research. This paper describes the usage of a negotiation protocol called SLNP (service level negotiation protocol) to achieve an agreement for an end-to-end QoS guarantee across heterogeneous domains using different local QoS models for wireless and wired technologies. SLNP uses Web services technologies to...
Thanks to its cost-effectiveness and wide deployment, the 802.11 WLAN is considered today as the de-facto wireless access network for the last mile connection. In this regards, QoS provisioning in 802.11 WLAN for multimedia services is becoming a main objective that should be enforced to enable reliable commercial offers. To reach this goal, the different mechanisms proposed by 802.11 standards, including...
Convergence of digital video broadcasting networks and IP networks represents undoubtedly the main evolution in next generation of services combining one-way digital television and interactive Internet applications. Within this mixed context, an important issue arises concerning the management of resources between IP applications and DTV services. The paper investigates this issue and presents a solution...
The actual trend in the IT (information technology) market is to create a new environment that will enable end-users to access a variety of services (TV/Radio programs, Internet, Multimedia applications, Games ...), wherever they are, whenever they want and whatever terminal they use. No existing solution exists that allows the common user to have access, instantly and in real time, to his desired...
Convergence of digital video broadcasting networks, from one hand, and IP wireless networks, from the other hand, represents undoubtedly the main evolution in next generation of services combining digital television and interactive Internet applications. This cross-industry synergy is jointly driven by the growing number of mobile devices willing to access the Internet and the large-scale and low-cost...
Audio and video streaming over the Internet is becoming very attractive and popular. Thus, there is a need to provide efficient delivery of such applications to the growing number of demanding users. In addition, new types of devices, transportable and mobile are emerging rapidly. Now, common users are expecting to access their favorite Internet services anywhere, and through any equipment (laptop,...
Next generation networks consist of the convergence of all the types of networks, from cellular, broadcast to IP-based, with QoS, mobility and security functions assured, and designed to transport multimedia and data services over the same medium. The ATHENA approach is heading toward this by proposing a powerful concept of hybrid wireless metropolitan networking area that interconnects different...
The tremendous interest received by Internet applications over the last decade, on one hand, and the emergence of the digital switchover, transition from the analogue to the digital TV, on the other hand, convey the trend for the convergence of broadcasting and IP-based networks. Permitting the access to IP services inside a broadcasting context already represents an evolution in next generation of...
