A wastewater treatment plant prediction in your computer The Källby wastewater treatment plant was set-up in a mathematical model reflecting its actual behaviour. Are the commonly available measurements good enough to perform a simulation? What kind of outcomes can we expect? After you have read the heading and the introduction, I guess that two proper questions swirling around in your head migh
Robots in factories and vehicles on our roads are rapidly reaching the point of automation. Commercial markets require high standards of safety and reliability, which in turn demands strict requirements on software and hardware. This thesis presents an analysis of driver assistance for a hydro-foil speedboat using LiDAR technology. The LiDAR sensor measures 2D positions of surrounding objects and
This paper deals with queues and insurance risk processes where a generic service time, resp. generic claim, has the form U boolean AND K for some r.v. U with distribution B which is heavy-tailed, say Pareto or Weibull, and a typically large K, say much larger than EU. We study the compound Poisson ruin probability psi(u) or, equivalently, the tail P(W > u) of the M/G/1 steady-state waiting time W
A full understanding of the properties of substellar objects is one of the major challenges facing astrophysics. Since their discovery in 1995, hundreds of brown dwarfs and extrasolar planets have been discovered. While these discoveries have enabled important comparisons with theory, observational progress has been much more rapid than the theoretical understanding of cool atmospheres. The reliab
Spider silks combine basic amino acids into strong and versatile fibers where the quality of the elastomer is attributed to the interaction of highly adapted protein motifs with a complex spinning process. The evaluation, however, of the interaction has remained elusive. Here, we present a novel analysis to study silk formation by examining the secondary structures of silk proteins in solution. Us
BACKGROUND: There is uncertainty about the relevance of animal foods to the pathogenesis of ischemic heart disease (IHD). We examined meat, fish, dairy products, and eggs and risk for IHD in the pan-European EPIC cohort (European Prospective Investigation Into Cancer and Nutrition). METHODS: In this prospective study of 409 885 men and women in 9 European countries, diet was assessed with validate
One can take advantage of the influence of a polymer conjugated with a protein to control the thermal stability and the deployment of the protein. Here, the structural properties are reported of the protein–polymer conjugate myoglobin (Mb)-poly(ethyl ethylene phosphate) (PEEP) in the native and unfolded conformations, in order to understand the respective roles of the protein and of the polymer si
Sweden has during the past decades experienced increasing challenges in suburban, segregated areas: the inhabitants have different cultural and socio-economic backgrounds but despite that, face similar problems. Many inhabitants lack relevant networks as well as other opportunities to become a part of the society. These inhabitants claim they don´t have the “keys” to understand their society and iSweden has during the past decades experienced increasing challenges in suburban, segregated areas: the inhabitants have different cultural and socio-economic backgrounds but despite that, face similar problems.

Characterization of emissions from fires in a laboratory-controlled environment are presented in this report. The project is initiated by the CERN HSE Unit and is called FIRIA, Fire-Induced Radiological Integrated Assessment. The objective of FIRIA is to enhance the knowledge of aerosols emitted from fires in order to develop dispersion models of radiologically-activated material in case of fire.
Inom nuvarande forskning om Internet of Things (IoT) finns det inte många studier som har tittat på användarperspektivet eller på hur företag som är verksamma inom IoT avväger användarupplevelse när de utvecklar IoT-produkter. Syftet med denna studie är att undersöka hur användarupplevelsen tas hänsyn till under utvecklingsprocessen för IoT. Den syftar också till att undersöka i vilken utsträckninIn current research of Internet of Things (IoT), there is limited research on the user perspective and even less on how companies operating in the field consider User Experience (UX) when developing for IoT. The aim of this thesis is to investigate how UX is considered during the development process of IoT. It also includes exploring to which extent this is done with a data-driven approach. The st
Idag har det blivit otroligt viktigt med ett miljömässigt ansvarstagande, speciellt vad gäller elproduktion. Här presenteras ett arbete där prestandabedömningen av dagens mest termodynamiskt effektiva fossila kraftverk, kombikraftverk, revolutioneras.Power production has a vital role in the functioning of society and will have a major part in the future of environmental and economical sustainability. Therefore, efficiencies of power plants are always a subject to improvements in order to utilise resources as efficient as possible. A Combined Cycle, combining a gas turbine topping cycle and a steam turbine bottoming cycle, is a widely used conf
The railway makes an extensive barrier in the landscape. To lower the impact of this barrier, and to allow people to easily pass it, level crossings are implemented. A level crossing is an intersection in the same plane between railway and road. Here traffic of all sorts meet with railway vehicles, which is why level crossings are one of the most distinct points of conflict in the entire railway s
Rätten till asyl utgör en av de grundläggande mänskliga rättigheterna och den garanterar att en asylsökande ska få frågan om sin flyktingstatus prövad i ett förfarande med visa garantier. Beslut i asylärenden är av stor betydelse för den enskildes liv och felaktiga beslut kan medföra allvarliga kränkningar av den enskildes mänskliga rättigheter. Inom asylrätten gäller som grundläggande princip attThe right of asylum is one of the fundamental human rights which guarantees that a person who seeks asylum will have his or hers status as a refugee, tried with some guarantees. Decisions made in an asylum case are of great importance for the individual and wrong decisions can lead to serious violations of the individual’s human rights. Within the asylum law is a fundamental principle which states
Ecosystem services have been widely discussed as of late, and more so than ever, has the topic of resilience and sustainable city planning taken an important role in the debate over how we can meet the present challenges concerning livable cities. The costs and the benefits of urban trees is an important factor in sustainable city planning and their consideration early in the planning stages canno
An experimental study is carried out to investigate the combustion process in a Wartsila 34SG spark-ignited lean burn four-stroke large bore engine (bore 340 mm) by means of optical diagnostics when operating on natural gas. The main focus of this work is to gain knowledge about in-cylinder combustion phenomena when igniting a lean air/fuel mixture with pre-combustion chamber induced jets. Especia
The interaction of water vapor with ice remains incompletely understood despite its importance in environmental processes. A particular concern is the probability for water accommodation on the ice surface, for which results from earlier studies vary by more than 2 orders of magnitude. Here, we apply an environmental molecular beam method to directly determine water accommodation and desorption ki
