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

Popular Abstract in Swedish Autonoma nervsystemet är den delen av nervsystemet som vi inte kan styra viljemässigt och som reglerar organismens grundläggande livsprocesser som andning, matsmältning, ämnesomsättning och blodcirkulation. Autonoma nervsystemet förser praktiskt taget alla inre organ med nerver. Det indelas i en sympatisk och en parasympatisk del med i huvudsak motsatta effekter på kropAbstract The aims of the present thesis were to examine neuropeptide Y (NPY) responses in different human and guinea pig vascular beds and in cultured human vascular smooth muscle cells (VSMC) and to characterize, with different NPY agonists and the specific NPY Y1 receptor antagonist (BIBP3226), the NPY receptors involved. NPY-induced strong and potent contractions in human cerebral and subcutan

Emergence of multiple-function products (MFPs) poses a variety of challenges and risks for achieving sustainable consumption and production as well as fair consumer society and universal design. We overviewed MFPs from these viewpoints and then, focusing on product standard as a means to create mechanisms to reduce environmental loads from products, elucidated advantages and limitation of five app

Results of a recent European research project MAnaging Speeds of Traffic on European Roads (MASTER) are presented. Speed management is described as a two-step process where target speeds for different kinds of roads are determined first, and then various measures and tools are applied in order to adopt such speed. Current practice and main problems in speed management are described. The various im

Popular Abstract in Swedish Kroniskt obstruktiv lungsjukdom (KOL) är en allvarlig folksjukdom vars huvudsakliga orsak är tobaksrökning. Det är den enda av de viktigaste dödsorsakerna som ökar och år 2020 beräknas KOL utgöra den 4:e vanligaste dödsorsaken i världen. Flera studier har försökt att bestämma förekomsten (prevalensen) av KOL i befolkningen men tyvärr har de oftast använt olika metoder oBackground – Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality worldwide. However, there is little information on the prevalence and particularly on the incidence of COPD. Also, apart from the importance of tobacco smoking and a1-antitrypsin deficiency, information on contributing risk factors for the development of COPD is limited. Hypotheses – 1. Spirometry
