An indoor positioning system (IPS) is a system to locate objects in indoor environments using radio waves, magnetic fields, acoustic, optical and video signals or other sensory information with help of a number of known reference positions. Nowadays, indoor positioning based services are used in a wide variety of areas and indoor positioning is getting considerable attention from both research and
With the rise of Internet of Things (IoT) accessories such as network attached cameras, light bulbs and thermostats are all constantly connected to the Internet and security concerns must be taken seriously. If a bug exists in an application it could be hacked by a malicious adversary that then could harm the underlying system, leak information or attack other devices or networks. Applications sho
Projektet syftar till att skapa möjlighet för boende och verkande på landsbygden, nära naturen, utan att vara beroende av daglig pendling till staden. Arbetet ska ses som ett konstruktivt alternativ till den stadsutglesande exploatering av landsbygden som tonger rådande norm för den byggda miljön. Arbetet handlar om att skapa en plats där subjektiva värden kan ges uttryck genom arkitekturen och dä
Four technical indicators are tested on 14 return-series, covering the years 2000 – 2016 and representing 3 different asset types: equity, commodity and currency, with a further division of equity into developed and developing markets. The indicators assessed are Moving Averages with fixed and variable holding periods, MACD, and RSI. The purpose is to determine if there are any differences in the
The relationship between the male and the female function in the simultaneous hermaphroditic flatworm Macrostomum lignano has been intensively studied on a phenotypic level. The results from these studies largely coincide with predictions that derive from sex allocation theory, which assumes a trade-off between the allocation of resources to the sex functions. Results from a recent experimental ev
This is the report for a master thesis work which concerns the challenge of automating a reach stacker. A reach stacker is a vehicle that lifts and moves containers. This report should be seen as a preliminary study which handles automation concepts, simulations and sensors. Research questions answered are: Which areas would benefit most from driver assistance, What kind of control is needed for t
Om inte statusen på Sveriges byggnadsbestånd förbättras kommer miljömålet ”God bebyggd miljö” inte kunna uppfyllas. Då miljömålet beaktar många aspekter måste ett holistiskt synsätt gälla vid genomförandet av åtgärder i byggnadsbeståndet. För att kunna göra detta måste en dialog föras kring viktiga aspekter på byggnadens samtliga områden mellan inblandade parter. Om en parameter ändras riskerar deCurrently, Sweden faces a major environmental challenge. If the status of its building stock doesn’t improve, the environmental goal “En god bebyggd miljö” will not be reached. Since this goal considers a wide range of aspects it’s essential that the same holistic approach is considered when implementing measures on the building stock. For this to be possible, an extensive dialogue needs to be hel
The production of TMP (Trimethylolpropane) is important for many applications, and is used as alkyds in paint and lubricants among others. The reactions producing TMP consist of two major reaction chains, Aldol condensation and Cannizzaro reaction. To get a deeper understanding and improve the running conditions the kinetic expressions for the reactions were examined. The aim of this paper was to
Antibodies have become immensely important reagents within biomolecular research and analysis as well as in medicine. Monoclonal antibodies are the largest class of biological drugs and with an increasing number of therapeutic antibodies approved for clinical use the need for efficient purification strategies is vast. Today, most antibodies are purified using affinity chromatography based on Prote
The building industry accounts for a large part of the world’s carbon dioxide emissions. At the same time the awareness of sustainable construction and production phase has increased and focus has been directed towards the material wood. Likewise, continuing urbanisation requires multi-storey buildings made of wood which brings along certain difficulties and challenges. Due to the low mass of wood
Syftet med litteraturstudien var att belysa strålningsreducerande åtgärder vid datortomografiundersökningar för vuxna patienter. DT undersökningar har ökat med 28% mellan 2005 och 2008. Med allt mer DT undersökningar behövs det en säker rutin för att skydda strålkänsliga organ såsom gonader, thyroidea, bröst och ögon. Litteraturstudie genomfördes och 10 artiklar granskades. Resultatet delades in i
Sammanfattning Denna pilotstudie hade som syfte att undersöka om ACT-baserad grupprehabilitering inklusive modifierad värderingskompass kunde öka deltagarnas förmåga att leva närmre sin värderade riktning inom områdena hälsa och sexuell hälsa. Mixad metod har använts med dels kvantitativ data från mätning med Distresstermometer, HADS, BIS och värderingskompass före, under och efter intervention ocAbstract The purpose of this pilot study was to examine if ACT-based grouprehabilitation with a modified Value Compass could enhance the participants capacity to live closer to their valued direction within the areas health and sexual health. The study used quantitative methods and qualitative methods to capture the experience of the intervention. The quantitative data was acquired with Distressth
Energy poverty (EP) is, in the scholarly literature, defined as a household’s inability to obtain a socially and materially acceptable level of energy services in the home. This is a widespread issue affecting an estimated 50 to 125 million people in Europe. Measures to tackle EP have yielded successes using proactive area-based schemes that target groups of households in the same geographic are
The development of maritime safety is often triggered by accidents. The purpose of this study is to learn how mass evacuation with survival crafts can be improved at sea, by reviewing the publicly available information from some of the most recent accidents. Information has been collected and analyzed from official investigation reports, passenger statements and the reporting of media. In addition
This essay connects to an ongoing discussion and debate on the usefulness and accuracy of the theories and the conceptual apparatus developed by the French theorist Henri Lefebvre. From an analytical reading of Lefebvre’s book The Urban Revolution, I make an original interpretation of Lefebvre’s arguments by tracing them back to Hegel’s syllogism and Marx’s two departments of social reproduction.
This thesis investigates Stockholm Municipality’s own-price elasticity for organic milk procurement and cross-price elasticity between organic and conventional milk procurement during 2008-2013. Using log-linear specifications with fixed effects, organic milk was found in most specifications to be relatively elastic, while the cross-price elasticity between organic and conventional milk suggests t
Patterns of local adaptation are expected to emerge when selection is spatially heterogeneous and sufficiently strong relative to the action of other evolutionary forces. The observation of local adaptation thus provides important insight into evolutionary processes and the adaptive divergence between populations. The seaweed fly Coelopa frigida exhibits an inversion polymorphism in all population
We have investigated the synthesis of anti-β-Hydroxy-α-amino Esters from the corresponding β-Keto-α-amino Esters. The coupling of Asymmetric Transfer Hydrogenation (ATH) with Dynamic Kinetic Resolution (DKR) allows us to control the relative and absolute stereochemistry of the product. The procedure uses a 1:2 mixture of formic acid and triethylamine as hydrogen source, and (S,S)-[RuDPAE(mesitylen
The purpose of my thesis is to examine if the financial crisis 2008-2009 effects economic gender equality in Sweden during (2008-2009) and after (2010-2015) the crisis and if so, how. The purpose is also to analyse if the outcomes are consistent with Gary S. Becker´s theoretical framework the taste discrimination model and the division of labour model. I define economic gender equality by using th
