Three standard approaches of finding Value at Risk; age weighted historical simulation, volatility weighted historical simulation and t – distribution were compared with Value –at – Risk calculated using generalized extreme value theory during the period 2000 to 2010 to see which approach that would give the most accurate forecast of actual losses during the two volatile times within the time fram
För att kunna bemöta en föränderlig omgivning där krav och förutsättningar ständigt förändras blir det allt vanligare att företag som sysslar med mjukvaruutveckling väljer att börja hantera projekt enligt den agila principen. Att anamma ett nytt sätt att arbeta kräver en omställning av alla inblandade inte minst för projektledaren. I denna uppsats har vi valt att undersöka vilka hur problem och mö
Equipment Fluids & Utility (EFU) is one of nine segments within Alfa Laval. The segment has experienced initial problems with sales volumes on the emerging markets so far entered, even though there is a seemingly large potential. No clear reason for this has been identified, and the management of EFU wants an efficient solution to the problem. The problem was to investigate what areas are affe
Syftet är att kartlägga och analysera hur noterade telekombolag, verksamma i Sverige, redovisar flerkomponentsavtal. Vidare utreds huruvida det finns behov av ökad vägledning i IFRS för detta redovisningsområde. Avslutningsvis sammankopplas dessa två dimensioner med vilka upplysningar som lämnas och vilken påverkan organisationsspecifika interna faktorer har. Ett kvalitativt synsätt har använts fö
Undersökningen behandlar sprint-retrospektiv som är ett centralt moment inom SCRUM men även inom andra agila systemutvecklingsmetoder. Inom SCRUM delas utvecklingsprojekt upp i flera mindre iterationer, så kallade sprintar. Sprint-retrospektiv är en reflekterande del inom SCRUM som ska hållas mellan varje sprint. Detta är ett tillfälle där teamet ska reflektera över föregående sprint, ta upp saker
Syftet med uppsatsen är att undersöka hur de förändrade kraven på Försvarsmaktens soldater reflekteras i deras rekryteringskampanjer. Samt vilka motiverande incitament som tas upp. Genom avskaffandet av värnplikten har Försvarsmakten blivit tvungen att tävla om arbetskraften med andra organisationer på arbetsmarknaden. Utifrån detta har det undersökts vilken bild av soldatyrket som framträder ur F
Cancer är en otrevlig sjukdom, som drabbar många människor. Man söker ständigt nya och bättre sätt att bota patienter eller åtminstone lindra sjukdomens framfart. Ett vanligt sätt att behandla cancer är med strålning. Strålningen kan bestå av sk fotoner. Fotoner är samma slags partiklar som t.ex. vanligt ljus. Skillnaden är att de fotoner som används vid strålbehandling av cancer har högre energi "Purpose: The aim of this study was to investigate whether inversely planned intensity modulated radiation therapy (IMRT), using the clinical radiotherapy equipment at hand in our department, renders any advantages regarding dose distribution over conventional radiotherapy for head and neck cancer patients in the ARTSCAN (Accelerated RadioTherapy of Squamous cell Carcinoma in the head And Nec
Detta arbete handlar om en behandlingsteknik för hudterapi där lågenergetiska elektroner utnyttjas för strålbehandling där patienten står eller sitter på en roterande plattform. För att behandlingen skall få ett lyckat resultat krävs en viss stråldos (den absorberade energin per massenhet) till patientens hud. För att kontrollera att dosen är rätt används normalt mätningar med olika detektorer. DeBackground and purpose: This study refers to a rotational radiotherapy technique for the treatment of mycosis fungoides. Patients are irradiated by a high dose-rate low-energy electron beam while they stand on a rotating platform. This report presents a first effort to use the Geant4 simulation program to calculate the relation between the stationary and rotational depth dose distributions in an e
UNICEF reports and daily newspaper reports suggest that street children are excluded from existing child rights facilities in Bangladesh. To examine the situation of social exclusion of street children, this paper examined the development policies for children in Bangladesh to understand how the existing policies can protect street children‟s rights and how they could enjoy country‟s currently ava
A new, robust technique for preparing highly selective molecularly imprinted films (see Figure) is presented. Spin-coating is used to spread a pre-polymerization mixture on a substrate, which is subsequently cured with UV light. Important aspects of this technique include the use of a novel polymeric porogen dissolved in a low-volatility solvent to generate porous morphologies with enhanced bindin
Observational and longitudinal observational studies (LOS) provide essential information about the course and outcome of rheumatic disorders that cannot be provided by randomized controlled trials, and they constitute the major clinical scientific communication in rheumatology. There has been no consensus as to the full and appropriate content of LOS. This report defines a core set of domains and
Antibody-based microarray is a novel technology with great promise in biomedicine that will provide unique means to perform global proteome analysis. In the process of designing the high-density antibody microarrays required, several critical key issues have been identified that remain to be resolved. In particular, there is a great need for specific and selective approaches enabling non-purified
Adsorption to microcrystalline cellulose (Avicel) of pure cellobiohydrolase I and II (CBH I and CBH II) from Trichoderma reesei has been studied. Adsorption isotherms of the enzymes were measured at 4 degrees C using CBH I and CBH II alone and in reconstituted equimolar mixtures. Several models (Langmuir, Freundlich, Temkin, Jovanovic) were tested to describe the experimental adsorption isotherms.
We consider a Casimir apparatus consisting of two perfectly conducting parallel plates, subject to the weak gravitational field of the Earth. The aim of this paper is the calculation of the energy-momentum tensor of this system for a free, real massless scalar field satisfying Neumann boundary conditions on the plates. The small gravity acceleration (considered here as not varying between the two
This study explored time-frequency analysis of surface electrocardiograms in patients with persistent atrial fibrillation for monitoring atrial drug action. Drug loading over 3 days with oral flecainide (n = 13) or amiodarone (n = 17) organized the fibrillatory process expressed by decreased atrial fibrillatory rate, increased rate stability, and decreased exponential decay. Effects were more pron
To investigate the influence of sulfonated polysulfone (sPSU) in membrane–electrode assemblies (MEAs), sPSU-based gas diffusion electrodes (GDEs) and sPSU membranes were studied both as complete MEAs and as separate components in assembled MEAs at 60–120°C. The complete sPSU MEAs showed mass-transport limitations, irrespective of ion exchange capacity, compared to Nafion MEAs. Cyclic voltammetry a
We present a batch method for recovering Euclidian camera motion from sparse image data. The main purpose of the algorithm is to recover the motion parameters using as much of the available information and as few computational steps as possible. The algorithm thus places itself in the gap between factorisation schemes, which make use of all available information in the initial recovery step, and s
Tantalum spectra, emitted from a hollow cathode, have been recorded with a Fourier transform spectrometer in the region 2000–5000 Ů The observed hyperfine patterns of Ta II have been analyzed, yielding center-of-gravity wavelengths for 199 lines and hyperfine constants for 38 even and 97 odd levels of Ta II. Improved energy level values have been derived. The laboratory data have been used for a s
Muramic acid (Mur) is found in bacterial peptidoglycan ( PG) whereas 3-hydroxy fatty acids (3-OH FAs) are found in Gram-negative bacterial lipopolysaccharide (LPS). Thus Mur and 3-OH FAs serve as markers to assess bacterial levels in indoor air. An initial survey, in a school, demonstrated that the levels of dust, PG and LPS (pmol m(-3)) were each much higher in occupied rooms than in the same roo
