  1. 1. Architectures for application transparent proxies : A study of network enhancing software

    Författare :Björn Knutsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Communication; Proxies; Internet; Information technology; Informationsteknik; Computer Systems; Datorteknik;

    Sammanfattning : Proxies, software deployed inside the network, play a fundamental role in the Internet by providing enhanced functionality to the network. Deployment of proxies is a flexible way of extending the Internet architecture with new services and to cope with problems that were not foreseen at the time the original Internet protocols were defined.

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antonovsky; back pain; BMI; body mass index; Bygghalsan; cohort study; coping; EQ-5D; excess weight; leg pain; LSS; lumbar spinal stenosis; obesity; ODI Oswestry disability index; overweight; patient-centered; patient-physician relationship; patient-perspective; patient-related-outcome-measure; PROMs; qualitative study; spinal stenosis; salutogenesis; salutogenic; sciatica; spine surgery; suffering; Swedish spine register; Swespine; VAS; weight loss; weight change; Orthopaedics; Ortopedi;

    Sammanfattning : During recent decades, lumbar spinal stenosis (LSS) has become the most common indication for spine surgery, a change that coincides with a higher worldwide prevalence of overweight and obesity. Thus, surgical treatment of LSS in the overweight and obese population is common and increasing in scope. LÄS MER

  4. 3. A Multidimensional Filtering Framework with Applications to Local Structure Analysis and Image Enhancement

    Sammanfattning : Filtering is a fundamental operation in image science in general and in medical image science in particular. The most central applications are image enhancement, registration, segmentation and feature extraction. LÄS MER

  5. 4. Distributed Peer Discovery in Large-Scale P2P Streaming Systems : Addressing Practical Problems of P2P Deployments on the Open Internet

    Författare :Raul Jimenez; Seif Haridi; Björn Knutsson; Arnaud Legout; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Peer-to-peer (P2P) techniques allow users with limited resources to distribute content to a potentially large audience by turning passive clients into peers. Peers can self-organize to distribute content to each other, increasing the scalability of the system and decreasing the publisher’s costs, compared to a publisher distributing the data himself using a content delivery network (CDN) or his own servers.
