This thesis explores the parametric and nonparametric approaches for estimating Value at Risk and Expected Shortfall through foreign exchange exposure. The data for this study was provided by Trelleborg Group. We look at the translational risk on the balance sheet when translating the Groups investments in foreign subsidiaries to SEK. In the parametric approach we make the assumption that the po
The vegetation component in climate models has advanced since the late 1960s from a uniform prescription of surface parameters to plant functional types (PFTs) PFTs are used in global land-surface models to provide parameter values for every model grid cell With a simple photosynthesis model we derive parameters for all site years within the Fluxnet eddy covariance data set We compare the model pa
The effect of future changes in temperature and precipitation patterns on arctic ecosystem functioning is often assessed using state-of-the-art ecosystem models. Many models however lack detailed representation of wintertime processes, as pointed out by recent studies (Wang et al. 2016, Slater and Lawrence 2013). This bias may influence the derived outputs, such as soil temperature, permafrost ext
Handeln med varumärkesförfalskade produkter, som länge har ansetts som en ganska harmlös företeelse som konsumenten varit väl införstådd med, har utvecklats till en väloljad miljardindustri där såväl rättighetsinnehavaren, samhället och konsumenten riskerar att lida skada. De varumärkesförfalskade produkterna består inte längre av dåligt imiterade solglasögon utan av professionellt utformade kopioCounterfeiting has long been considered a rather harmless phenomenon. However, counterfeiting has evolved from a small-scale activity into one on an industrial scale. It has come to pose a serious threat, not only to the interests of the right holder, but to the consumers and the society as a whole. Counterfeit products are no longer just poorly crafted copies of sunglasses; today they are profess
An archaeological excavation made within contract archaeology almost invariably means that the site is destroyed. This means that the documentation, which can be seen as the site’s remaining archive, is extremely important. In this master’s thesis the written digital documentation from eight excavations made within Swedish contract archaeology between 2000 and 2013 is examined using the technique
Pleural and tracheal injuries remain significant problems, and an easy to use, effective pleural or tracheal sealant would be a significant advance. The major challenges are requirements for adherence, high strength and elasticity, dynamic durability, appropriate biodegradability, and lack of cell or systemic toxicity. We designed and evaluated two sealant materials comprised respectively of algin
A recombinant Baeyer-Villiger monooxygenase, BVMO4 from Dietzia sp. D5 has been previously reported. The enzyme exhibited good thermostability and was active with a wide range of cyclic ketone substrates but catalysed poorly the conversion of cyclohexanone to caprolactone. The present work focuses on protein engineering of BVMO4 to improve the conversion of cyclohexanone. Thus, a structural model
Hunnebostrand var under 1900-talet ett av Sveriges främsta stenhuggerisamhällen. Här höggs och bearbetades stenen för att sedan fraktas till platser över hela världen. På 70-talet lades stenhuggeriverksamheten i Hunnebostrand ner, men spåren efter industrin lever kvar i samhället än idag. En viktig plats i Hunnebostrand under stenhuggeriepoken var Udden. Här höggs sten från Norra Högeberg och plaThis project examines the potential design of a visitor center named ”Stenens Hus” in Hunnebostrand, Sweden. The village was a prominent stone quarrying community in the 20th century, and the quarrying industry left its mark on the town even after it was shut down in the 1970s. One important place in Hunnebostrand during this era was Udden, where stone from Norra Högeberg was quarried. The site
The primary focus of this Master thesis is to study how industrial house building can be implemented during production of rental flats under the terms of public procurement. In order to determine a suitable working process as well as presenting a possible architectonic result of the process, a case study is carried through. A housing projekt is designed on a site i Malmö, where the commisioner is
The accuracy of NOAA AVHRR NDVI maximum value composites can be poor due to interference from several sources, including cloud cover. The objectives of this paper are; 1. to accurately quantify noise in this imagery over Africa using geostatistics, and 2. to test four compositing techniques that may be able to reduce this noise. The nugget of the variogram model is used to compute standardized noi
Populärvetenskaplig sammanfattning: Mössbauerspektra är en metod som används för att bestämma hur ett mineral, eller molekyl, är uppbyggt. Man undersöker ett visst grundämne, inom geologin undersöker man oftast järn. Efter att ha analyserat ett prov i spektrometern kan man få uppgifter om var och hur järnet sitter i mineralet, eller molekylen. Metoden bygger på att man skickar gammastrålning av eThe Mössbauer effect is used in this work to determine the oxidation and site occupation in biotites that have been treated in different pHs. The work also gives an introduction to the theory behind the Mössbauer effect as well as Mössbauer spectroscopy. It is obvious that the pH has a significant role in the oxidation of the biotites, the more acidic the sample the more it will be oxidised. It is
Deep learning has the potential to drastically increase the accuracy and efficiency of prostate cancer diagnosis, which would be of uttermost use. Today the diagnosis is determined manually from H&E stained specimens using a light microscope. In this paper several different approaches based on convolutional neural networks for prostate cancer classification are presented and compared, using th
Many industries have benefited from modularisation; while in the architecture, engineering and construction (AEC) industry, the concept of modularisation is associated with dimensional coordination. This has added to an already extensive list of challenges due to market size and the concept of economies of scale in AEC industry, to name but a few. Moreover, there is a myth that the AEC industry is
Aim: Phantoms are used daily in the clinic for radiotherapy. As more realistic phantoms are requested, 3D printing could be used but the design of a realistic phantom is difficult. The purpose of this project was to design and 3D print an anthropomorphic phantom that could be used for verification of complex treatment such as stereotactic arrhythmic radioablation treatments without the use of pati
