Chronic musculoskeletal pain: a multifactorial process

Popular Abstract in Swedish Bakgrund En grundförutsättning för detta avhandlingsarbete var att smärta i rörelseapparaten kan studeras som ett samlat begrepp. Med två undantag, fibromyalgi och reumatoid artrit, avstod vi därför från att beskriva smärtan utifrån specifika diagnoser. Detta förhållningssätt har stöd i den mest vedertagna definitionen av smärta, som arbetats fram av IASP (InternationaThe aim was to study prevalence, assessment methods, and risk factors of chronic musculoskeletal pain, as well as effects on health status in a general population setting. A postal survey to a representative sample of 3928 subjects aged 20–74 years in 2 municipalities on the west coast of Sweden was followed by clinical examinations of selected subjects, and a three-year follow up survey to 2425

Contextual dependencies and gender strategy

Analysts are often asked to help deliver systems that have a great mix of performance and features. Unfortunately, problematic organizational gender related issues have sometimes been degraded and treated as unrelated to technological issues. While ISD in general is trying to ensure support for businesses, we might in the future expect more than just a gender-ignorant quality-measure in the way th

Performance Modelling and Control of Server Systems using Non-linear Control Theory

All service control nodes, for example SCPs, HLRs, and MSCs, are constructed as a server system with one or more servers that process incoming requests. Since service control nodes are sensitive to overload, admission control mechanisms are often implemented. In this paper, we model and analyse admission control mechanisms for server systems with control theoretic methods. We develop a nonlinear s

Dealing with the combinatorial explosion of the morphological matrix in a "manual engineering design" context

The morphological matrix is an important element of the engineering design methodology and is present in many textbooks. This method originally aimed at generating an exhaustive set of solutions for a given problem, by decomposing it into subproblems, finding solutions to each subproblem, and combining them. One issue associated with the morphological matrix has been the necessity to deal with the
