Framed Slotted ALOHA (FSA) is an anti-collision technique in current and future standards of RF-ID systems, as in ISO/IEC CD 18000-6. The number of tags present in the field is a crucial parameter to apply FSA algorithms in an optimal manner. Therefore, a lot of effort is spent on the estimation of this parameter and a range of different estimation(More)
PURPOSE This article reports the user-oriented evaluation of a text- and content-based medical image retrieval system. User tests with radiologists using a search system for images in the medical literature are presented. The goal of the tests is to assess the usability of the system, identify system and interface aspects that need improvement and useful(More)
The VISual Concept Extraction challenge in RAdioLogy (VISCERAL) project has been developed as a cloud–based infrastructure for the evaluation of medical image data in large data sets. As part of this project, the ISBI 2014 (International Symposium for Biomedical Imaging) challenge was organized using the VISCERAL data set and shared cloud– framework. Two(More)
Providing efficient access to the huge amounts of existing medical imaging data is a highly relevant but challenging problem. In this paper, we present an effective method for content-based image retrieval (CBIR) of anomalies in medical imaging data, based on similarity of local 3D texture. During learning, a texture vocabulary is obtained from training(More)
The Kernighan/Lin graph partitioning heuristic, also known as min-cut, has been enhanced over decades and successfully adopted for circuit partitioning. During last years extended versions have been developed to address functional partitioning as it is needed to solve the much investigated co-design problem of partitioning a system's coarse-grained(More)
Development of complex System on Chip (SoC) for modern communication systems has become more and more challenging. A designer has to bridge the gap between the requirements of the system at algorithmic level and its cycle true hardware description; the latter being synthesised for an Application Specific Integrated Circuit. This development requires(More)
