Value at Risk (VaR) is a popular measurement for valuing the risk exposure. Correct estimates of VaR are essential in order to properly be able to monitor the risk. This thesis examines a copula approach for estimating VaR for portfolios of commodities. The predictions are made from a semi- parametric model with Monte Carlo methods. The underlying model is constructed by choosing the best fit from

Problemområde: Turism är en stadigt växande bransch och många reser för att koppla bort från vardagen. Samtidigt ökar medveten om hållbarhetsfrågor vilket genererat ett intresse för verksamheters ansvarstagande i frågan. I studien undersöks hotellens vattenbesparande strategier eftersom det fanns exempel då de påverkats av gästens upplevelse. Det identifierade problemområdet är således hotellens b

För att motverka klimatförändringarna har Sverige satt som mål att växthusgasutsläppen från inrikes transporter ska minska med minst 70 % senast år 2030 i förhållande till år 2010 (utom inrikes luftfart). För att uppnå detta krävs en satsning på förnybar energi. Skånetrafiken har målsättningen att bli fossilbränslefri senast år 2020, dessutom vill de använda biodrivmedel som genererar så lite växt

In our thesis project called (S)ink we combine an experimental computational approach to flooding and sea level rise with a defined architectural context, with the emphasis on a spatial experiences and aesthetics. We explore new emergent fabrication techniques together with a “poetic” concept of a memory and adaptation.

The mobile telecommunication network is growing year after year and it will soon move into the high speed 5G and Internet of Things technology. These new technologies will improve the throughput and data connectivity and due to that the energy consumption in radio and digital units may increase in a Radio Base Station (RBS). There are more than 500 000 off-grid RBSs in the world which are powered

Ni-Ti systemet har en stor mängd tillämpningar, inom områden så spridda som biomedicin och robotteknik. Detta beror till stor del på den intermetalliska föreningen NiTi, vilken är en minnesmetall. Utöver denna egenskap är den intermetalliska föreningen dessutom biokompatibel, har bra mekaniska egenskaper och god resistans mot korrosion. Studier på NiTi har visat att temperaturerna kopplade till deThe Ni-Ti system has a broad range of applications, in areas as diverse as biomedicine and robotics. This is in large due to the NiTi intermetallic compound, which exhibits the shape memory effect. In addition to this property, the intermetallic compound is also biocompatible, has good mechanical properties and good corrosion resistance. Studies on NiTi has shown that the temperatures at which the

The construction sector is one of the biggest contributors to global CO2 emissions and buildings account for a significant part of the energy use in Sweden. Population growth in combination with economic development is putting more pressure on the environment, resulting in escalating consumption trends and larger quantities of raw material extraction. Policies and directives are promoting a circul

A confocal microscope is built to examine molecular powders, and in particular the (PhSn)_4S_6 cluster, that emits white light when irradiated with infrared laser light. The confocal microscope operating at long working distances is assembled and characterized. The components of the setup are first chosen according to requirements of the planned experiment. Thereafter, the microscope is assembled

Det här arbetet ger en enkel introduktion till teorin för så kallade Lie-grupper (uppkallade efter den norske matematikern Sophus Lie), som är en slags matematiska objekt som befinner sig i gränslandet mellan två av matematikens huvudområden: geometri och algebra. Å ena sidan kan Lie-grupper betraktas som släta mångfalder, vilket betyder att de är kurvor, ytor eller högre-dimensionella analoger In this work, we present some of the basic concepts and constructions in the theory of matrix Lie groups. For each matrix Lie group, we use the matrix exponential to construct a Lie algebra, and we then use the matrix exponential to show how different properties of the Lie group affect the Lie algebra and vice versa. In particular, we use the Baker–Campbell–Hausdorff formula to prove a one-to-one

The sexual assaults reported on New Year’s Eve 2015 in Cologne and the reactions towards it have changed political and public opinion on the issues of migration, gender equality, and sexual violence in Germany. Based on theories from postcolonial studies, feminist studies, security studies, approaches on collective trauma, and emotion studies this thesis analyzes ‘Cologne’ as a trauma which has en

The purpose of this qualitative study is to explore female athletes experiences of being a women in a space that has historically been dominated by men: the gym. Using Sara Ahmed’s idea of orientation and spatiality it analyzes how sportswomen moves through different positions in different rooms, the position as a woman and the position as an athlete. The concept of orientation examines how differ

In many countries, GMO policy-making has been characterised with a lot of controversy, participation and trust being the most pressing issues. The ongoing Ghanaian GMO policy-making is not spared of the controversy. The GMO Bill which was introduced in the Ghanaian Parliament in 2013 remained unpassed amid accusations and counter-accusations between government-led groups and civil society-led anti

Ever since the dawn of internet, a new wave of fast-growing software companies has emerged. The M&A scholars have struggled to find appropriate valuation mechanisms for unprofitable companies with ultra-high revenue growth. To overcome the uncertain future, a contractual provision called earnout is often used. An earnout is a contractual provision in a M&A-deal that states the seller of th

Polymerer är långa kedjor av upprepade segment och finns både som naturliga polymerer (proteiner, DNA, gummi, och cellulosa) och som syntetiskt framställda polymerer (plaster, nylon, etc.). Många polymerer är känsliga för ändringar i deras miljö och termoresponsiva polymerer, som har studerats i detta arbete, ändrar egenskaper drastiskt vid ändringar i temperaturen. Vid en viss kritisk temperatur,Thermoresponsive polymers with a lower critical solution temperature, LCST, have attracted interest in the development of new ``smart materials'', which change properties in response to external stimuli. Polymers with an LCST near physiological temperatures are especially relevant in biomedical applications, most notably perhaps in drug delivery systems. The aim of this work is to investi

I dagens globaliserade samhälle väljer allt fler svenskar att bosätta sig utomlands och leva i en annan kultur än sin ursprungskultur. Det behövs därför mer forskning och kunskap kring utlandssvenskens upplevelser. Denna studie fokuserar på svenskar bosatta i Portugal för att undersöka den globaliserade främlingen. Syftet med denna studie är att på en mikronivå analysera individens egen upplevelse

The aim of this study was to examine how organisations present their arguments regarding international homosexual adoption. The material of this study consisted of texts and the analysis have been based on the arguments from referral responses regarding the bill SOU 2001:10 (Children in homosexual families). Four themes were identified that seemed to pay a significant role in discussion of the iss

The aim of this study was to examine and illuminate how people who are born deaf experience their encounters with administrative authorities. The study was based on qualitative interviews. Several themes were identified in the interviews: knowledge, deaf competence, accessibility, communication, interpreter usage, audism and discrimination. The analysis was based on the notions of accessibility, s
