The purpose of this thesis was to reduce the start-up and restart time of a hemodialysis machine by targeting time consuming control loops. This was done by investigating different techniques of modelling to find the best combination of versatility and conformity to the process. Finding the best controller was done by evaluating different controllers in simulations with the model in MATLAB/Simulin

The aim of this study was to examine attitudes surrounding the needle exchange program in Malmö and Lund in Sweden. More specifically the aim was to examine how the staff of the needle exchange program experience the attitudes surrounding the needle exchange program and if/how these attitudes affect them in their work. The analysis of nine interviews with staff members revealed similarities in how

In June the 23, 2016 United Kingdom will hold a referendum on their EU-membership. One of the triggers was the letter that David Cameron sent to Donald Tusk November 10, 2015: “A settlement for the United Kingdom in a reformed Union“. The purpose of the present thesis is to make a profound analysis of David Cameron’s letter, analyzing the proposals and demands he places on EU. Cameron has four ma

This report is made in order to evaluate the fire safety for the personnel and patients at Ystad hospital. A risk analysis was conducted, focusing on hazards related to fire, and on the client's wishes it was determined that the analysis should be done on the section of the hospital called building 17 and that the writers especially should consider the risk of arson. Through the analysis two d

This report is evaluating the evacuation safety of a sports hall in Borås, Boråshallen. It is a 6 floor building containing a basket hall and auxiliary training facilities. Fire scenarios of varying severity were evaluated. Computer modelling was done in a CFD software, FDS, to find the time to critical conditions. That in turn was compared to egress time calculated by evacuation simulation progra

Confronting Chinese E-commerce has increased rapidly in the past decade as well as its potential growing rate in the future, International E-commerce companies have realized the necessities of localization to attract more Chinese online consumers. However, many of them seem to have a hard time to compete with the local sites. This study aims to investigate design elements that are attracting the C

This Master’s thesis describes a method for real-time estimation of a vehicle’s mass for automobiles using recursive least squares. The method has its foundation in the longitudinal dynamics of the vehicle and is designed to be easy to adapt to different vehicle models. The mass estimation rely on a underlying road grade estimation and driveline efficiency estimation for every gear. The road grade

Sveriges plansystem är omfattande och processerna tar ofta lång tid. För att kunna möta akuta behov av bostäder och främja en effektiv samhällsutveckling behövs vissa ventiler i systemet. Tidsbegränsade bygglov tillåter avsteg från vissa förutsättningar som normalt behöver uppfyllas för permanenta bygglov. Syftet med arbetet är att utreda hur regeln om tidsbegränsade bygglov i 9 kap 33 § PBL tolThere is a big need for new residential areas in Sweden but the process of exploitation and building is time-consuming. Temporary Building Permits allow construction, even though some of the normally required criteria are not fulfilled. An ease in the legislation is useful in order to meet urgent needs and to achieve an efficient land use. The purpose of this thesis is to study how the regulatio

In recent year, many countries have achieved the economic growth to different extent all over the world, but more problems were emerged along with the process of development. The problem of income distribution has been raised and became a chronic concern for researchers and governments ever since. Not only the developing countries, but also the developed countries are suffering the inequality issu

Geographic Information Systems (GIS) have acquired greater relevance as tools to support decision-making processes, and during the last decades they have been used in conjunction with Multi-Criteria Decision Analysis techniques (GIS-MCDA) to solve real-world spatial problems. GIS-MCDA can be generally divided in Multi-Attribute and Multi-Objective techniques. Until now most of the applications of

This study investigated whether anchored prices induced biased choices and time estimations for the pursuit of an equal discount and if different degrees of social distance influenced these biases. A new measurement for quantifying the relative degree of bias was also proposed. A sample group of 142 students were tested from a university in southern Sweden. In a repeated measure design, each parti

The analysis of peptides using mass spectrometry produces signals, where intact and fragmented peptides are observable as specific signal peaks. This report investigates how signal processing and supervised learning, along with specialized peak detection algorithms, can improve the analysis of such peptide signals in a mass spectrometry technique called Data Independent Acquisition. To make this i

Vehicle Routing Problem (VRP) är en variant på det mer kända Han- delsresandeproblemet. VRP går i stort ut på att finna rutter för en flotta av fordon som ska besöka ett antal kunder och i vissa fall optimera dessa rutter för att minimera sträckan som fordonen färdas. Det förekommer ofta flera bivillkor, exempelvis att en viss kund måste besökas innan en viss tidpunkt. Jag har undersökt lättheten The Vehicle Routing Problem (VRP) is a variant of the more famous Travel- ling Salesperson Problem. The VRP basically consists of finding the routes for a fleet of vehicles to visit a number of customers and in some cases op- timize this route to minimize distance traveled. Often there are many side constraints, e.g. a certain customer must be visited before a certain time. I have investigated the

Lake sediments have lately been explored as a 10Be archive, complementing previous research on ice cores and marine sediments. 10Be is an important proxy as it can be used to study past solar activity, a factor which affects the climate. Where other methods studying solar activity only cover a brief period of history, 10Be has the potential to go further back in time. The concentrations of 10Be st

In Sweden, between 1964 and 1975, approximately one million dwellings were raised in the so called million programme. Due to their age and often neglected maintenance regarding both building envelope and installations, in many cases, comprehensive retrofitting is now required. The aim with this study was to theoretically investigate the energy saving potential and cost-effectiveness of integrating

I jakten på nya och bättre solceller har en teknik som bygger på färgämnesmolekyler innehållandes en metall seglat upp som en möjlig framtidskandidat. Dock lider dessa av att de använder dyra och sällsynta metaller vilket gör att de inte är optimala för massproduktion. Om man istället hade kunnat använda färgämnen som innehåller järn så hade dessa solceller kunnat göras billigare då järn är ett avThis thesis had the goal of investigate two dierent DFT methods, PBE0 and B3LYP*, and what eect those had on the calculations to see if the new DFT method, B3LYP*, would give results that better match em- pirical data. To do this three iron complexes were investigated with both methods so that the results could be compared and conclusions drawn. A forth complex were investigated with only PBE0 to

Fathers in the Nordic countries were among the first in the world to gain the right to paid parental leave. The overall uptake has however been low, despite various attempts to increase it. This paper compares characteristics of fathers in four Nordic countries, to identify important determinants of parental leave uptake. The relationships were tested using logistic regression models. Support for

This study builds on the idea that the conceptualisation and implementation of human rights education in the classroom and other instances in the local community can be different from the way in which the concept is understood and described in international policy documents. The literature review indicates that the context and local actors can affect the way human rights education is carried out.

Tillsyn av mindre hästgårdar Författare: Madeleine Holm Sjöbo kommun är en attraktiv kommun för hästhållare eftersom de sandiga markerna erbjuder möjligheten till torra beteshagar året runt. Kommunen har under 2015 och 2016 tagit ett krafttag när det gäller att genomföra tillsynsbesök på de mindre hästgårdarna. Tillsyn innebär att miljöinspektörer från kommunen åker ut på besök till gårdarna och Sjöbo municipality in the southern parts of Sweden is well suited for keeping horses since the sandy soil and, for the region, cheap land makes it possible to provide good grassing for horses all year around. In this project nutrient leakage from horse farms was investigated by conducting inspection. The inspections focused on the small horse farms with three up to ten animal units and less than t
