A fundamental problem in studying peer-to- peer networks is the evaluation of new protocols. This paper presents OverSim, a flexible overlay network simulation framework based on OMNeT++. It was designed to fulfill a number of requirements that have been partially neglected by existing simulation frameworks. OverSim includes several structured and(More)
In this paper, we present the development and application of current image processing techniques to perform MRI inter-subject comparison of knee cartilage thickness based on the registration of bone structures. Each point in the bone surface which is part of the bone-cartilage interface is assigned a cartilage thickness value. Cartilage and corresponding(More)
PURPOSE To compare the precision and accuracy of 3.0-T and 1.5-T magnetic resonance (MR) imaging in the quantification of cartilage volume by using direct volumetric measurements as a reference standard. MATERIALS AND METHODS The local animal experimentation committee did not require its approval for this study. Porcine knees were obtained from an(More)
A common manifestation of osteoarthritis (OA) of the knee is the morphological degeneration of articular cartilage. In vivo magnetic resonance imaging (MRI) offers the potential to visualize and analyze quantitatively morphology such as cartilage thickness and volume. The purpose of this work was the development of new image processing techniques and(More)
Taxonomy, the science of describing and naming of the living world, is recognized as an important and relevant field in modern biological science. While there is wide agreement on the importance of a complete inventory of all organisms on Earth, the public is partly unaware of the amount of known and unknown biodiversity. Out of the enormous number of(More)
