With growing urbanization and increase in energy demand for space heating and cooling in buildings, reliability, security, distribution of energy and its efficient end use is of utmost importance particularly when emissions from energy use and indoor thermal comfort of the end users isof question. Numerous solutions have been put forth in the field of effective distribution of thermal

The laboratory consists of a XenX x-ray irradiator (XStrahl) for experimental radiobiology, with supporting equipment for cell culture applications, such as laminar flow cabinets, CO2 incubators, and a hypoxia workstation. The XenX unit is designed as a radiotherapy machine in miniature. It consists of a 225 kV x-ray source, mounted on a rotatable gantry allowing irradiation of specimens from all

Detta forskningsområde fokuserar på hur hållbarhetsövergångar påverkar naturresurser och leveranskedjor, hur dessa förändringar uppfattas påverka säkerheten och hur dessa uppfattningar utlöser respons från olika aktörer. Hållbarhetsövergångar påverkar materialiteten i försörjningskedjor och infrastrukturnätverk. Att minska användningen av fossila resurser och kolintensiva produktionsmetoder ökar This research area focuses on how sustainability transitions impact natural resources and supply chains, how these changes are perceived to affect security and how these perceptions trigger response by different actors. Sustainability transitions impact the materiality of supply chains and infrastructure networks. Reducing the use of fossil resources and carbon intensive production methods increa

Popular Abstract in Swedish Denna avhandling behandlar olika metoder för datakompression och speciellt metoder som är lämpliga för komprimering av digitala bilder. Avsikten med datakompressionen är att finna en representation av den ursprungliga datan (tex en bild) som upptar mindre plats på tex ett skivminne.In this thesis various topics in universal lossless source coding are discussed and analyzed. The main focus in this work is on lossless data compression of grayscale still images. Such images are, for example, frequently occurring in medical imaging. Based on theoretical considerations and empirical observations new compression algorithms are presented that are, in terms of compression performan

An instrumental and experimental setup for soft x-ray spectroscopy meeting the requirements of a closed source for radioactivity is described. The system consists of a vacuum sealed cell containing the sample, mounted on a tubing system to ensure compatibility with most standard manipulators. The soft x rays penetrate a thin x-ray window separating the interior of the cell from the vacuum in the e

The sparse iterative covariance-based estimation (SPICE) algorithm is promising for hyperparameter-free sparse source location for time-division-multiplexing multiple-input-multiple-output (TDM-MIMO) radar systems, with well-documented merits in resolution enhancement and sidelobe suppression. Regrettably, the method typically requires a large number of iterations to converge, each requiring high-

BACKGROUND: We present a C++ class library for Monte Carlo simulation of molecular systems, including proteins in solution. The design is generic and highly modular, enabling multiple developers to easily implement additional features. The statistical mechanical methods are documented by extensive use of code comments that - subsequently - are collected to automatically build a web-based manual. R

Varje år tar cirka 1500 personer sitt liv i Sverige. Det är en minskning sedan 1980-talet men de senaste femton åren har minskningen stannat av. Enheten för klinisk suicidforskning arbetar med olika områden inom suicidforskning med det övergripande syftet att bättre förstå hur suicid kan förebyggas. •Område A: Psykopatologi och riskfaktorer för patienter med risk för framtida suicid. Vi undersökeSuicide research is of importance to find new strategies to prevent suicide. Each year approximately 800 000 people in the world, and 1500 people in Sweden commit suicide. The suicide rate has not decreased over the last 15 years. The Unit for Clinical Suicide Research cover different areas within this field. • Area A: Psychopathology and risk factors. Our group investigates how psychopathology

Preeklampsi är ett allvarligt graviditetsrelaterat tillstånd som årligen drabbar 10 miljoner kvinnor världen över. Etiologin är ännu okänd och diagnosen ställs baserad på moderns kliniska symptom: högt blodtryck och någon organpåverkan som debuterar efter 20 veckors graviditet. För närvarande är förlossning den enda ”boten”. Preeklampsi medför en ökad långsiktig risk för utveckling av hjärt-kärlsjPreeclampsia is a severe pregnancy-related condition that annually affects 10M women worldwide. The etiology is largely unknown and diagnosis is currently based on maternal clinical symptoms: high blood pressure and organ damage manifesting after 20 weeks of gestation. Delivery is currently the only cure. Increased long-term risk for cardiovascular diseases and stroke after preeclampsia point to i

Eye data quality varies greatly with the eyetracking system, the individual characteristics of participants, the recording environment, and the operator. The quality of the signal has important repercussions for which eye movement measures are valid, and what conclusions can be drawn from them. Reading research often has high demands in terms of spatial precision and accuracy. Reliably detecting e

Genom att kombinera kunskapen från kliniskt aktiva läkare och forskare tror vi att vi snabbt och effektivt kan få kunskap om de spektrala egenskaperna hos hudcancer och jättecellartrit och översätta detta till avbildningsverktyg för detektion av tumörgränser och diagnostik. Genom att mäta blodflöde under och efter periorbital rekonstruktiv kirurgi strävar vi efter att uppdatera kirurgiska teknikerBy combining the knowledge of clinically active medical doctors and researchers we believe that we can rapidly and effectively gain knowledge on the spectral properties of skin cancer and giant cell arthritis and translate this into imaging tools for tumor border outlining and diagnosis. Through monitoring of blood flow perfusion during and following periorbital reconstructive surgery we aim to up
