This thesis offers a study on the performance of two different pairs trading approaches, the Distance Method and the Stochastic Spread Method implemented on the Swedish stock market for the period 2005-03-01 to 2014-03-06. The thesis also expands in the existing literature on the stochastic spread approach to pairs trading by proposing a pair selection method and an alternative way of generating t

Hållbarhetsaspekterna i företagens redovisningar blir mer detaljerade och omfattar nu hela företagets värdekedja. Redovisningarna blir mer transparenta och allt fler hållbarhetsaspekter har integrerats i årsredovisningen. Förändringarna beror främst på införande av ramverk samt intressenternas inflytande. Utvecklingen mellan företagen är dock inte homogen

Generellt faller det tillräckligt med nederbörd i Uganda för att naturligt bevattna grödor och djurhållning. Men med klimatförändringar har säsongsmönstren ändrat sig och blivit mer extrema. Detta påverkar hur marken kan användas och har dessutom stor inverkan på jordbrukarna som är i stor omfattning beroende av sin mark, både av ekonomiska skäl och för livsmedelssäkerhet. Denna studie har två syfIn general Uganda receives enough rainfall to rain-feed crops and pasture but as climate is changing the seasonal patterns are expected to become more extreme. This influences how the land can be used, and has a strong impact on the farmers who depend on their land for economic income and food security. This report has two aims. The first is to identify the farmer’s experiences of climate change a

This paper investigates disparities in opportunities of obtaining a higher education between the population with rural household registration and the population with urban household registration. The analysis consists of a quantitative comparison of data and a qualitative study analyzing the reasons of the found disparities based on Chinese scientific publications and statistics supplemented with

Genom att undersöka hur situationen ser ut för nyutexaminerade studenter som ska ta sig ut på arbetsmarknaden har jag formulerat ett syfte med studien som lyder: försöka förklara tre personers erfarenheter av att leva i en övergångsperiod mellan högskolan och arbetsmarknaden. Jag har intervjuat tre personer som alla har tvingats till alternativa sysselsättningar i väntan på ett jobb som matchar d

Uppsatsen har för avsikt att komma fram till i vilken omfattning utvecklingsmetoden RUP stödjer användarmedverkan. Genom att beskriva begreppen RUP, användarcentrerad systemdesign och användarmedverkan med hjälp av litteratur har jag kunnat sammanställa ett par frågor i avsikt att utföra en intervju med tre systemvetare. Resultatet från det empiriska materialet visade att systemvetarna upplever at

The goal of condition-based maintenance (CBM) is to base the decisions whether or not to perform maintenance on information collected from the machine or component of interest. A condition-based maintenance tool should be able to diagnose if the component of interest is in a state of failure but the ultimate goal of a CBM tool is to be able to estimate time until failure, either in terms of remain

Strukturellt unga och N-S-ligt strykande högmetamorfa metadiabaser förekommer i Östra segmentet längs västkusten från Varberg till Kullaberg, och i inlandet mot öster till den Svekonorvegiska fronten. Dessa basiska gångar skär ställvis gnejsiga strukturer i värdbergarterna. Några har välbevarade primärmagmatiska strukturer som exempelvis lagring och “cross-bedding”. Metadiabaserna består av högtryStructurally late and roughly N-S trending high-grade metamorphic dolerites occur in the Eastern Segment along the coast from Varberg to Kullaberg and inland (eastwards) to the Sveconorwegain Front. Locally these mafic dykes cross-cut the gneissic foliations of the host gneisses. Metadolerites have a high-pressure granulite facies metamorphic mineral assemblage and some of them have well-preserved

A new low pressure fuel system implementation for Scania’s trucks is being investigated. The main challenge consists in exchanging the mechanical pump with electrical pumps. The electrical pumps must then be controlled to supply exactly the demanded amount of fuel at the required pressure. System redundancy allows a lot of degrees of freedom influencing the final performance. This thesis studies t

With the consolidation of automotive control processes onto single highperformance ECUs the issue of running, and thus scheduling, processes of varying criticality on a single CPU has moved to the fore. This has resulted in a number of new algorithms for scheduling such systems, for example Adaptive Mixed Criticality (AMC). This project attempts to measure the performance of some of these algorith

This study presents structural and electrical properties of individual, upright standing III-V semiconductor nanowires obtained by scanning probe microscopy (SPM). The work is divided in two major parts. First, we report on optoelectrical characterization of individual InP nanowires in their free standing geometry utilizing scanning tunneling microscopy (STM). We present measured current-voltage (

Variability of atmospheric circulation is considered one of the most important factors causing interannual and interdecadal variability of freshwater amount that is discharged from the continents. Here it is presented an analysis of the relations between the discharge variability of five major rivers in the Mediterranean basin (i.e. Adige, Arno Ebro, Po and Rhone) responsible for the 70% of total

Effective and rapid solutions are something that all companies in the construction industry increasingly strive for. Therefore, there is talk of industrialized building, which aims at an efficient process from the design phase, to the product completion. One reason why effective and quick solutions are sought is because of competition between firms within the industry. A construction company with

Syfte: Studiens syfte är att se hur dagligvaruhandeln kan generera konkurrensfördelar genom användning av Corporate Social Marketing avseende konsumenters matsvinn. Detta har granskats genom att analysera dagligvaruhandelns egna hantering och marknadsföring av matsvinn samt konsumenters hantering och åsikter av matsvinn i hushållen. Metod: Kvalitativ undersökningsmetod med semi-strukturerade inter

Den som mottagit en förmånersättning enligt SFB kan bli återbetalningsskyldig om det visar sig att utbetalningen varit felaktig. Även om den felaktiga ersättningen inte orsakats av den försäkrade själv kan det bedömas att det skäligen borde ha funnits en insikt om att utbetalningen varit felaktig. När det finns en god man eller förvaltare förordnad för den försäkrade uppstår en oklarhet i vems insOne who has received a benefit payment under socialförsäkringsbalken may be liable to repay if it turns out that the payment was erroneous. Even if the erroneous payment was not caused by the insured, it may be judged that there should have been a realization that the payment was erroneous. When there is a trustee or administrator acting for the insured, there is a lack of clarity in whose realiza

Clustering of data points is a classic problem that so far has no perfect general solution. Most existing solutions are computational expensive or simplied due to the combinatorial aspect of the problem. Genetic algorithms are becoming more and more popular due to their ability to solve large scale optimization problems. This thesis investigates the idea of creating a genetic algorithm able to per

When analyzing sedimentary sequences, results which are based solely on macroscopic observations, can lead to misleading and incomplete conclusions. Therefore these observations need to be complemented by analyses on a microscopic or atomic scale, such as through biological, chemical or physical methods. This approach is especially necessary when analyzing marine sedimentary cores from the Baltic
