There is a widespread perception that camera surveillance has a negligible effect on crime prevention. These notions are largely based on conclusions from research studies that are difficult to transfer to Swedish conditions. Better research is needed on how camera surveillance works in a Swedish context.
The post-failure convergence of shortest path routing (SPR) protocols used in IP networks can be too slow to meet the restrictive requirements (i.e. maximum allowable delay, jitter, etc.) of the multimedia services and therefore new protection/restoration mechanisms combined with IP routing are of interest. The article addresses the optimization of three potential rerouting mechanisms based on the
In this era of wireless hysteria, with continuous technological advances in wireless communication and new wireless technologies becoming standardized at a fast rate, we can expect an increased interest for wireless networks, such as ad hoc and mesh networks. These networks operate in a distributed manner, independent of any centralized device. In order to realize the practical benefits of ad hoc
Popular Abstract in Swedish Avhandlingen pressenterar resultat från fyra studerade områden; En undersökning av hur nya kolvrörelser (volym-vevvinkel relationer) påverkar utsläpp, effekt och verkningsgrad; En undersökning av hur kväveoxid påverkar självantändning och knack; En undersökning av hur vätgas och reformerad metanol (RMG) kan utnyttjas som bränsle, dels i vanliga tändstiftsantända (SI) moThe results presented in this thesis can be divided into four areas of investigation: Investigation of the effect of new volume-crank angle relations on engine emissions, power and efficiency; investigation of nitrogen oxides effect on auto ignition and knock in SI engines; investigation of premixed SI and HCCI engine operation with the alternative fuels hydrogen and reformed methanol gas (RMG); s
In this paper the Petersen and composition matrices that modellers are now familiar with are used as a basis to construct interfacing models between subsystems considered in wastewater treatment. Starting from continuity considerations and a set of transformation reactions between components used in the two models of the subsystems to be interfaced, a set of linear algebraic equations needs to be
This book is about how we verbally formulate thoughts about pictures, scenes, and visual events. The focus of the analysis lies on spoken descriptions from a communicative and cognitive perspective.
An algorithm for the detection and location of sudden bursts in water distribution networks combining both continuous monitoring of pressure and hydraulic transient computation is presented. The approach is designed for medium and large bursts that are the result of the sudden rupture of the pipe wall or other physical element in the network and are accompanied by the transient pressure wave t
A womans life 1753-1841 through her diaries. Märta Helena Reenstierna was an aristocratic woman who lived at a manor near Stockholm in Sweden, but she lost all her eight children and finally also her husband, and survived them all. We can follow her life in her diaries, with her joy an sorrow, and the daily life.
There is still a need for new agents which improve upon the therapeutic index of tiotropium, the current standard of care for many patients with chronic obstructive pulmonary disease (COPD). We examined in patients with COPD the efficacy of single doses of AZD9164, an M(3)-selective muscarinic antagonist, to identify an appropriate dose-range for future studies. COPD patients (n = 28) inhaled AZD9
Abstract Aim: To investigate the risk of small for gestational age (SGA) births in relation to maternal history of cardiovascular disease (CVD) across two generations and additionally to analyse maternal CVD risk based on number of SGA offspring. Methods: We used register data from 1.4 million women and 2.7 million offspring. The outcome measures were risk of being SGA in relation to maternal tota
The relative benefits and harms of hormonal treatment (HT) versus no or deferred HT in patients with nonmetastatic prostate cancer (PCa) relapse after primary curative therapy are controversial.
Primary objective was to identify the (1) relationship of clinical severity of urosepsis with the pathogen spectrum and resistance and (2) appropriateness of using the pathogen spectrum and resistance rates of health-care-associated urinary tract infections (HAUTI) as representative of urosepsis. The secondary objective was to provide an overview of the pathogens and their resistance profile in pa
