The three-dimensional optoelectronic locomotion analysis system SELSPOT II was used for kinematic studies of hind limb locomotion patterns. Two groups, 11 sound horses and 15 horses suffering from hind limb lameness, were examined at the trot. Both graphical and quantitative analyses were compared in sound and lame horses. The parameter hip acceleration(More)
The authors present their experience of 27 cases with repairs of defects following radical maxillectomies with free flaps. A total of 28 flaps were used (five latissimus dorsi, six scapula, 16 combination flaps of scapula and latissimus dorsi and one combination of scapula, latissimus dorsi and serratus anterior flap). Only one scapula flap was completely(More)
Many decentralized and peer-to-peer applications require some sort of data management. Besides P2P file-sharing, there are already scenarios (e.g. BRICKS project) that need management of finer-grained objects including updates and, keeping them highly available in very dynamic communities of peers. In order to achieve project goals and fulfill the(More)
Current developments on Service-oriented Architectures, Peer-to-Peer and Grid computing promise more open and flexible architectures for digital libraries. They will open DL technology to a wider clientele, allow faster adaptability and enable the usage of federative models on content and service provision. These technologies rise new challenges for the(More)
OBJECTIVE To evaluate and discuss the free flap reconstructive options for patients with partial and total maxillectomy defects. DESIGN Retrospective review of cases. SETTING Two tertiary referral centers. PATIENTS Fifty-one patients had partial or total maxillectomy defects resulting from oncologic surgical resection, and 7 had partial maxillectomy(More)
An essential issue in peer-to-peer data management is to keep data highly available all the time. The paper presents a replication protocol that adjusts autonomously the number of replicas to deliver a configured data availability guarantee. The protocol is based on a Distributed Hash Table (DHT), measurement of peer online probability in the system, and(More)
The introduction of Service Oriented Architectures enables the transition from integrated, centrally controlled systems to federated and dynamic configurable systems. Scalability and reliability are key requirements for such infrastructures. Due to the size and dynamic only decentralized and self-organizing systems are able to accomplish the previously(More)
The research in the paper is motivated by building a decen-tralized/P2P XML storage on top of a DHT (Distributed Hash Table). The storage must provide high data availability and support updates. High data availability in a DHT can be guaranteed by data replication. However, DHTs can not provide a centralized coordination guaranteeing data consistency upon(More)
Service oriented computing and peer-to-peer (P2P) computing are emerging technologies which provide, from the architectural point of view, scalability and flexibility. From their properties both architectures are quite similar, e.g. in both architectures nobody has a complete system overview and no central administration exists. Besides other challenges ,(More)
