The background for this master thesis is the stricter emission control requirement in heavyduty diesel engines at the same time as the demands for improved diesel engine efficiency are getting stronger. One approach to meet these demands is to increase the fuel injector pressure. A higher fuel injector pressure makes the fuel spray more finely dispersed into the cylinder and a better combustion is
Uppsatsen utreder relationen mellan de EU-rättsliga instrumenten tjänstedirektivet och yrkeskvalifikationsdirektivet. Särskilt utreds vad dessa direktiv har för konsekvenser för yrket trafiklärare i svensk rätt. Gemensamt för de båda direktiven är att de främjar den fria rörligheten genom att avlägsna hinder för yrkesverksamma personer som flyttar mellan medlemsstaterna. Detta sker dock på olika sThe essay investigates the relationship between the two EU legal instruments the Services Directive and the Professional Qualifications Directive. In particular, the essay investigates the impact of these directives on the profession of driving instructor in Swedish law. Common to the two directives is that they promote freedom of movement by removing barriers for professionals who move between Me
The Baltic Sea is one of the largest seas with brackish water and is sensitive ocean partly due to its long retention time and partly due to its high human load or the combination between the two. In Scania there are 33 municipalities where 16 of these are located along the coast. However, due to that the knowledge about coastal management varies between the municipalities Integrated Coastal Zone
The purpose of this thesis is to test whether the theories of reciprocal altruism, nepotism due to kin selection and costly signaling can explain patterns of human altruism. A new way of investigating this has surfaced since the introduction of mobile phone money transfers in areas where social sharing is frequently exercised. Data was collected from 167 respondents in Nairobi, Kenya on their late
In the laminator there are three laminator stations where protective layers are applied to the paperboard. In each station there are several rollers which help perform the lamination process, the most important rollers to be considered in this thesis are the nip roller and the chill roller. The nip roller is pushed towards the chill roller using hydraulic cylinders , thus creating a narrow contact
This thesis aims to aid the consultancy Living Institute in evaluating the perceived effects of the cross‐cultural training courses it provides to a wide variety of clients. To do this we study the company in relationship to its clients, mapping out its theoretical foundation as well as its strategies for teaching culture. In order to gain a deeper understanding of what the company teaches and how
Det är tonfallet i texten och den stiliserade formen som gör att hundboken "The Dog Owner’s Manual" verkar både roligare och trendigare än en vanlig hundbok. Genom att framställa hunden som en produkt, använda ett tilltal som liknar det i en teknisk manual och göra illustrationerna stiliserade har boken fått en ironisk prägel som känns unik. Med den här uppsatsen har jag velat klargöra v
The last part of the product design process is called embodiment design, it aims to give a “physical body” to the product so as to make it ready to use. It is on that particular part of the design activity that I was working, I was included in the research for the embodiment design team of the machine design division in LTH. The main research work was upon the process of this phase, to try to unde
This Master Thesis treats the problems involved with a dust explosion inside a filter unit. The project is a cooperation between AB Ph. Nederman in Helsingborg and the Mechanical Design Department of Design Sciences LTH, Lund. The Master thesis was carried out from December 2009 to April 2010. The initial phase of the project involves studies of the phenomena dust explosions, standards and regulat
Objective: To redesign the current assembly process of the Ektorp Sofa from IKEA in order to improve cycle times, quality levels and to reduce, if possible, costs associated with manufacturing, production times and materials. IKEA wants to increase either the productivity or the quality standard of the Ektorp Sofa by simplifying the processes involved in the construc-tion of the sofa and modernizi
Fouling of direct steam injectors and holding cells is a serious problem in the heat treatment of products in the dairy industry. The fouling limits the run time of a plant and increases the time for cleaning. Both these factors will increase the processing cost. Four different direct steam injectors are tested and evaluated using the criteria fouling of the injector, the stability of the injector

This thesis provides insight into Global Care Chains located between Italy and Ukraine. The countries under analysis represent different ends of the Global Care Chain, Italy being a country of immense immigration and Ukraine being on the other side as a country of large emigration. The women who migrate are mostly mothers and/or wives and their most common employment is in the reproductive sector
The final purpose of this project is to create a platform that leads to the improvement of the braking feeling by the users of heavy vehicles. The complexity of the problem lays on the different constraints: geometrical and functional, and as well on the interaction with a human operator. The task is to design a new electronic brake pedal, with the possibility to change the relationship between fo
This report is part of the Master thesis performed by Markus Jonasson and Alexander Mann at the Department of Design Sciences at Lund University. Markus and Alexan-der have studied to become Masters of Science in Mechanical Engineering with In-dustrial Design. Per Liljeqvist, senior lecturer in Industrial Design at the Department of Design Sciences is instructor. Robert Bjärnemo, professor in Mach
The aim of the project is to retrofit a 3-axis CNC milling machine from the late 80’s with a 5-axis head, a new controller, reducing the noise and the vibrations produced by the machine to achieve a healthy work and educational environment. At the same time, the purpose is to study the CNC milling machine within the marc of European Directives and Standards to improve the security features and ens
This paper tries to connect economic development and total fertility rate together and used two VAR model with the optimal lag respectively to analyze the impacts of economic conditions on total fertility rate in Denmark within half a century from 1956 to 2008. From the regression result of the first model VAR (4), there are slight difference in the impacts caused by GDP per capita, consumer price
