The main purpose has been to evaluate existing set points (thresholds) and suggest proper set points, for the regulation of the air change rate in a demand controlled mechanical ventilation (DCV) system. The DCV is controlled by measurements in the supply and exhaust air of the vapor content and volatile organic compounds (VOCs) for each dwelling in multifamily houses. Results have been achieved t

Developing systems by integrating Open Source Software (OSS) is increasingly gaining importance in the software industry. Although the literature claims that this approach highly impacts Requirements Engineering (RE) practices, there is a lack of empirical evidence to demonstrate this statement. To explore and understand problems and challenges of current system requirement–OSS component matching

Microcapsules with specific functional properties, related to the capsule wall and core, are highly desired in a number of applications. In this study, hybrid cellulose microcapsules (1.2 ± 0.4 μm in diameter) were prepared by nanoengineering the outer walls of precursor capsules. Depending on the preparation route, capsules with different surface roughness (raspberry or broccoli-like), and thereb

The overall aims of this thesis were to investigate the effects of an aerobic exercise program and the impact of migraine and co-existing TTH and NP in persons with these combined conditions. This thesis is based on four studies.In study I, a new questionnaire, Impact of Migraine, TTH and NP (Impact M-TTH-NP), was developed. This questionnaire covered pain, triggers, psychosocial,socioeconomic and

Children’s biographies are only rarely and more recently considered. In this paper, we make a case for thinking biographically about children’s relational lives. Using two qualitative case studies from research with children in middle childhood, in the UK and Sweden, we attend to the materiality of children’s biographies. We explore the way in which home spaces, possessions, family mementoes and m

Diffusion MRI is an imaging technique capable of inferring information about the tissue microstructure, based on magnetic resonance imaging (MRI). Diffusion MRI data can be analysed using tractography, a tool able to represent the structure of the white matter (WM) in the brain. Tractography is commonly used qualitatively, but in this report, an algorithm for quantitative tractography was develope

This thesis visits the forefront of algorithmic research on edge coloring of cubic graphs. We select a set of algorithms that are among the asymptotically fastest known today. Each algorithm has exponential time complexity, owing to the NP-completeness of edge coloring, but their space complexities differ greatly. They are implemented in a popular high-level programming language to compare their p

Sammanfattning I svensk rätt finns flera inskränkningar av den personliga avtalsfriheten. Pactum turpe är en av dessa och inskränkning innebär att vissa former av avtal som faller under den inte erhåller rättsordningens skydd. Under denna bestämmelse innefattas avtal som står i strid med lag eller goda seder, varav den senares innebörd är närmast omöjlig att fastslå. För att avgöra om ett avtal fa

There is some evidence that perinatal factors, specifically birth weight (BW), may be related to the onset of prostate cancer (PRCA). This case-control study, nested within the Malmo Diet and Cancer Cohort Study, used archived birth record data from 308 incident PRCA cases diagnosed between 1991 and 2005, and 637 age-matched controls among 4781 men born (1923-1945) in Malmo and Lund, Sweden. We ap

Experimental data on single file pedestrian movement has been analysed andimplemented in a prototype movement model. The prototype model is developed topredict movement of persons based on a first principle approach using basic populationdata such as age, height, gender and response time to adapt the walking speed in a crowd.The experimental data provide the biomechanical information needed in the

In the late nineteenth and for much of the twentieth century, an academic career in Sweden was highly dependent on what grade a scholar’s doctoral dissertation was awarded. Unless receiving a so-called “docent grade”, basically declaring the scholar eligible for seeking the title of docent (associate professor), the prospects of maintaining an academic career were bleak. Throughout the period, thiIn the late nineteenth and for much of the twentieth century, an academic career in Sweden was highly dependent on what grade a scholar’s doctoral dissertation was awarded.

Genetic trade-offs - which occur when variants that are beneficial in some contexts of natural selection are harmful in others - can influence a wide range of evolutionary phenomena, from the maintenance of genetic variation to the evolution of aging and sex differences. An extensive body of evolutionary theory has focused on the consequences of such trade-offs, and recent analyses of Fisher's geo
