Sweden faces an upcoming period where thousands of buildings built during the million program period will be in need of a façade renovation. There is a large energy-saving potential in these buildings, since they are often poorly insulated and often have a ventilation system without heat recovery. Performing energy-efficient renovation measures to a building are expensive, which results in that th

The goal of the thesis is to model stock prices as a stochastic process which exhibits reversion towards an equilibrium point, where the equilibrium point is set by fundamental data points of the company. The stochastic model is compared to the standard approach of using Geometric Brownian motion to simulate stock prices. The autocorrelations of a group of stocks are investigated. This has lead

This qualitative study seeks to highlight the contributing factors of social exclusion of asylum seekers and refugees in Glasgow. Deriving from an internship at the organisation Scottish Refugee Council in Glasgow, this study is based on primary data that has been gathered from a community conference with asylum seekers and refugees, as well as from interviews with staff from the organisation. Its

The influence wielded through private philanthropy has made a comeback to the academic and public discussion, as large foundations such as the Bill and Melinda Gates Foundation (BMGF) invest increasing amounts of money in national and international development efforts. This thesis researches one aspect of philanthropy that has received little attention in the debate on its implications for politic

Syftet med studien var att undersöka hur relationer till omsorgspersoner i barndomen har påverkat framtida kärleksrelationer hos en grupp vuxna. Studien ämnade både att lyfta fram hur gruppen själva menade att relationerna till omsorgspersonerna påverkat deras liv, och om relationsmönster från barndomen följt dem in i romantiska relationer i vuxenlivet. Kunde några av deras beteenden och egenskapeThe aim of this study was to examine how relationships to caregivers in childhood have affected future romantic relationships in a group of adults. The study is intended to highlight both how the respondents themselves understands how the relationships to their caregivers has affected their lives, and if relationship patterns from childhood have been reproduced in romantic relationships in adultho

Tidigare har byggandet av höga hus inte varit vanligt i Sverige, men på senare år har förändringar i samhället skett vilket lett till att höga hus blivit mer intressant. Vid dimensioneringen av höga hus uppkommer svårigheter och fenomen som inte behöver beaktas vid dimensioneringen av lägre hus. I detta examensarbetet tas en arbetsmetodik fram, vilken kan följas vid den preliminära dimensionerinThe construction of high-rise buildings has previously been limited in Sweden. Changes in society in recent years, related to urbanisation, economics and architectural standards have however resulted in a greater interest for the construction of high-rise buildings. When designing high-rise buildings, challenges are faced which often can be disregarded when designing lower buildings. In this diss

We live in a time where there is an increasing focus on the environment, in terms of classification of vehicle emission standards and environmental zones. Along with this and the fierce market competition that exists, it is odd that a greater effort has not been made in making material-transport more effective by renewing the tarmac on our road-network. The purpose of this report is to show the sa

Mikroföroreningar är små molekyler som är restprodukter från t.ex. läkemedel, hormoner, kosmetika samt mikroplaster. Då majoriteten av dessa inte renas i våra av- loppsreningsverk har mikroföroreningarna börjat ackumuleras i vattendrag och dess negativa inverkan på vattenlevande djur har börjat uppmärksammas. En av metoderna för att ta hand om och avskilja mikroföroreningarna i reningsprocessen äThis thesis investigates the feasibility of integrating Powdered Activated Carbon (PAC) in to chemical treatment in combination with disc filtration of tertiary wastewater. Jar and tube tests have been performed, where the suspension was filtered through a 10 μm disc filter from Hydrotech Veolia Water Technologies. The effluent has been analyzed for total phosphorus (TP), total suspended solids (T

Kan geofysiska undersökningsmetoder vid undersökning av förorenade områden bidra till att uppnå en giftfri miljö? Sverige lider idag av stora mängder giftiga ämnen i marken som dumpats av olika sorters industrier under åtskilliga år, från en tid då ekonomiskt välstånd stod högt på agendan och okunskapen om miljön var utbredd. De här föroreningarna riskerar nu att skada både människors hälsa och mA central part of the risk assessment of contaminated sites is to conduct surveys of the area to assess the need for remediation. Through literature and interview studies this essay examined how geophysical methods can help to improve the environmental risk assessment of contaminated sites in Sweden. The results point to five main strengths in combining geophysical methods with the conventional me

Dagens ekonomi är ohållbar eftersom det leder till en överkonsumtion av råvaror och andra resurser. Den cirkulära ekonomin är en idé om hur ekonomi kan vara baserad på cirkulära principer. En av de viktigaste principerna är att samhället måste arbeta för att nå högre upp i avfallshierarkin, genom att främja återvinning och förebyggande av avfall. En av byggstenarna i cirkulär ekonomi är affärsmodeToday's economy is unsustainable as it leads to the over consumption of raw materials and other resources. The circular economy is an idea for an economy based on circular principles. One of the key principles is that society must work to reach higher up the waste hierarchy, and prosecution of recycling and waste prevention. One of the circular economy's building blocks are business models

Register allocation is one of the most critical parts of an optimizing com- piler. Although a great effort has been put into researching how to allocate registers, not much of it has been focused on vector registers. This report seeks to find out what fundamentally new problems arise when allocating vec- tor registers rather than scalar registers, how the previously known problems change in vector

This thesis investigates possible problems due to pressurization of high staircases. The main problem arising when high enclosures are not pressurized in sections in the event of fire is that an imbalance of the pressure profile in the building occurs. Pressure difference between the stairwell and adjacent rooms becomes large enough that the doors to the stairwell may be difficult to open and clos

Bomull är en huvudkomponent i majoriteten av kläder som tillverkas och har därför blivit ett standardmaterial i dagens samhälle. Bomull odlas på flera platser runtom i världen, men bomullsväxten kräver ett speciellt klimat, stora jordytor samt en enorm mängd vatten för att trivas. De här kraven har gjort att produktionen av bomull inte kunnat hålla jämna steg med den ständigt ökande efterfrågan påTextile fibres made from cellulose is a plausible candidate for replacing cotton in the future. In order to create textile fibres from cellulose the cellulose must first be dissolved and proceeded by regeneration through spinning. In this study mainly the solubility of regenerated cellulose has been investigated. Micro crystalline cellulose (MCC) was regenerated by dissolving it in NaOH (2 M) and

This master thesis explores the feasibility of using genetic algorithms in order to automate the process of optimizing hyperparameters for artificial neural networks (ANN). Today there is no standard way to optimize hyperparameters for ANN; often they are set manually by trial and error. In order to explore the feasibility of using genetic algorithms to optimize hyperparameters for ANN, two algori

Riskområden med snabb föroreningsspridning via grundvatten – grafisk illustration i ArcGIS Enskilda avlopp utpekas allt oftare som en betydande källa till spridning av förorenande substanser och patogener. Hur kan man identifiera och visualisera transporttider för föroreningar baserat på ett områdes geologiska karaktär? Idag finns cirka 700 000 hushåll med enskilt avlopp i Sverige varav hälften The raw water source lake Vombsjön is situated in the center of southern Scania and provides drinking water by artificial groundwater recharge for approximately 450 000 inhabitants each day. More than 2800 households within the catchment of lake Vombsjön treats their domestic wastewater with a decentralized sewer system. The configuration of these sewer systems varies, but it is common to have som
