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

Studiens syfte var att nå en fördjupad förståelse av småbarnsföräldrars användande av interaktiva skärmar när de umgås med sina barn; vilken mening användandet har för individen och vilka följder detta kan få för relationen mellan förälder och barn. Semistrukturerade intervjuer genomfördes med åtta småbarnsföräldrar som sällan, ibland eller ofta använde sig av interaktiva skärmar. Tematisk analys The aim of this study was to gain a greater understanding of the usage of interactive screens by parents of young children, whilst interacting with their children; what role does the usage of interactive screens play for the individual and how does the usage affect the relationship between parent and child. Semi-structured interviews were conducted with eight parents of young children who rarely,

The main assignment for the Swedish Police, given from the government, is to 1) reduce crime and 2) increase safety so that people can feel safe where they live. A previous research resulted in the recommendation that the Swedish Police should work separately against the two goals. The motivation for the recommendation was that working separately against the goals would be the most efficient way o

Syftet med denna uppsats är att beskriva och analysera några fallföretag med avseende på deras process att framställa en hållbarhetsrapport samt deras utgivna rapport. Vidare vill vi diskutera det svenska lagförslaget och vad hållbarhetsrapportering kan bidra till. För att undersöka syftet har en kvalitativ och explorativ studie använts med ett tolkningsperspektiv och en induktiv ansats. Studien g

Denna uppsats är skriven inom ämnet medie- och kommunikationsvetenskap av Gustaf Nordahl och Gustav Berg, som under skrivandets gång studerar vid institutionen för kommunikation och medier vid Lunds Universitet. Uppsatsens titel är; Spelarens vardag - En studie av Identiteter och Subkulturer. I denna uppsats försöker vi hitta brytpunkten som finns mellan de två identiteter och kulturer en gamer be

The performed study is a qualitative case study of the company Business Sweden. An inductive research approach has been used where we started by observing Business Sweden and subsequently applied suitable theories. The aim with the paper is to describe and analyze the aspects of management control in a multinational hybrid organization, by observing the process of centralizing the responsibility o

Second generation immigrant women face an earnings disadvantage in the labor market in Sweden. The socioeconomic position of the parents has been shown to matter more than ethnicity. This study examines the effect of the immigrant parents’ education, as a measure for socioeconomic status, on their daughter’s earnings. In addition, the effect of parental education when both parents have the same ed

The peninsular centre of Newcastle has been disconnected from the city and Sydney with the removal of its train corridor. Using the unique landscape, history and street grid the design rejoins the peninsula both physically and culturally to the site. The masterplan proposes a system of green swale streets, a pedestrian axis, hillside viewpoints and lightrail anchored by a new harbourfront developm

There is a lot of research dedicated to understanding what makes firms successful, and that research has expanded to take on a systemic approach. Most developed nations are implementing some sort of cluster policy and firms in clusters are well known to perform better than their counterparts. This thesis suggests we borrow practises used to understand firms, to better understand nonprofit organiza

Having a specialized editor or IDE has become commonplace for many programming languages. Smaller languages, especially domain-specific ones that normally have very narrow usage areas, often lack such convenience features due to their naturally small user base. Tools for implementing editor support for these languages are called language workbenches. Unfortunately these often lack features for mor

I ett samhälle som blir allt mer tjänsteintensivt blir servicemöten en allt större del av vår vardag (Corvellec & Lindquist 2005: Svingstedt 2005) vilket gör att även intresset för dessa möten ökar. I denna studie undersöks servicemötet mellan chaufförer och deras kunder då det är en bransch där mötet med kund inte alltid resulterar i en mänsklig interaktion. Syftet är att belysa problematiken

Bakgrund: Förbättrad återhämtning efter kirurgi (fast-track surgery) innebär ett multidisciplinärt synsätt på den perioperativa vården för att möjliggöra en kortare vårdtid. Denna undersökning utgår ifrån patientens perspektiv och baseras på patientens upplevelser. Syfte: Syftet med studien var att postoperativt utvärdera patientrelaterade utfallsmått (PROM) och erfarenheter (PREM) hos kvinnor eft
