Konstruktion av beslag med dörrfunktion till spridarlucka

This thesis was performed at Zetterbergs Industri AB. Zetterbergs is designing, building and mounts body systems for trucks, including dumpers and tippers. The assignment for the thesis was to design a door hinge for a spreader gate. The spreader gate is the top of the two tailgates on a dumper or tipper and opens back and outwards when tipping the cargo. The spreader gate controls the mass flow of the material being tipped.

Standardisering kontra flexibilitet : En fallstudie av utvecklingsprocesser

Process standardization is a topic that has generated a lot of research and literature. At first, the focus was on production; today processes are used in all different kind of business areas.The aim of this study has been to analyze how processes can be applied on development businesses and how IT systems affect the result of the process. To accomplish this, we have asked questions such as what standardization is in a development process? Why are the processes standardized? What difficulties can appear with standardization? And how the IT-systems affect the result of the process?To answer these questions, we have preformed a case study on Saab. Saab is a well know Swedish company who are working with a project called the GMS-project, where they develop processes to cover the whole company´s business areas.The literature gives the reader an understanding of processes and standardization.

Plafondmålningar - Arkitektförbundet Måleri på duk, Skadefenomen och åtgärdsproblematik

The concept of large paintings includes panoramas, cycloramas and other paintings thatin size exceeds the normal magnitude of wall hung paintings. When these large paintingsare mounted in the ceiling, they are referred to as plafonds. When they are performedon canvas, certain kinds of structural distortions and stress occurs. In addition, becauseof their size and mounting high up in the ceiling, plafond paintings are often difficult tohandle, which leads to less or no maintenance. A plafond may therefore be left withoutattendance for many decades.This thesis has its focus on what happens with plafond paintings on canvas when they areexposed to gravitational forces, and the problems involved in restoring large paintingsmounted in the ceiling.

Mikroföretagens etablering : Vilken påverkan har förekomsten av lokala dominerande globala företag på etableringen av mikroföretag ägda av invandrare med stort kulturellt avstånd?

The purpose of the study is to examine and analyze the relation between the existence of global companies and given support to immigrant- owned companies with large cultural difference from public services. This helps answering the question "Which affect does the existence of local dominating companies have on the establishment of small companies owned by immigrants with large cultural differences?" This has been accomplished through a field study containing twelve interviews with small companies in two different cities and two interviews with the community officials in each city. The research was thereby narrowed to only treat the two cities in Sweden in order to examine the relation between public services support to small immigrant-owned companies and how the immigrants experience the support from them. The analyze was made due to a handful of theories such as the The network theory IP model, Hofstede's 4+1 model and the Product Life Cycle.

Samspel mellan miljo?politik, innovation och teknikutveckling : Fallstudier om svenska avlopp, kylska?p och bilar

Within process or manufacturing industries, the production of goods and services or the products themselves may have negative side effects such as pollution. An important task for environmental policy is to control and limit these pollutions, for example via regulatory measures. Although, the efficiency of such measures vary greatly between different industries and an increasingly important task for environmental policy is then to encourage companies to engage in environmentally motivated innovation. Governments can utilize other measures than regulation to indirectly decrease pollution. This thesis aims to analyze such activities and how it affects the innovativeness of wastewater treatment, refrigeration and automobile manufacturing industries.

Uptake of 137Cs by fungi and plants due to potassiumfertilization in Heby municipality in response to theChernobyl nuclear accident

The fallout from the Chernobyl nuclear accident resulted in large deposits of caesium, iodineand strontium as well as noble gases in various parts of Sweden. 137Cs has a radioactive halflifeof about 30 years and is therefore one of few radio-fission products remaining inmeasurable quantities in the Swedish soil. Radiocaesium behaves similarly to potassium insoil-plant systems and is easily absorbed by plants. It is important to understand how 137Csbehaves in different ecosystems in order to minimize the risk toward humans.The aim of this study was to determine how potassium fertilization influences radiocaesiumcontent in different forest plants and fungi. Potassium fertilizer was spread once in 1992 withapproximately 200 kg KCl per ha.

Inhysning av struts :

The Swedish ostrich production started about thirteen years ago and still there are no Swedish recommendations regarding ostriches? space requirements. The European Council give recommendations and the Swedish Board of Agriculture (SJV) has a proposal, but so far the producers follow Danish regulations regarding space requirements. The Swedish Animal Welfare Agency are about to set standards for the ostriches? space requirements, and therefore the Swedish ostrich producers, together with The Federation of Swedish Farmers (LRF) ask for a scientific background to these decisions. This thesis is a preliminary study at the prospect of a future experiment on which factors important for ostriches? space requirements and welfare will be examined more thouroughly.

"Harry Potter är inte lämplig i skolan" : En jämförande studie mellan serbiska och svenska lärares syn på litteraturundervisning.

This thesis is about Swedish and Serbian teachers and their views on how literature should be taught to students in high school. The twist is that these teachers live in two different European countries, and work under two different educational systems. Three of them work in Stockholm, Sweden and the other three in Belgrade, Serbia. The purpose of this thesis was to find similarities and differences in the practice of teaching literature among teachers in these two different educational systems. The teachers were interviewed separately and spoke freely about their views and methods when teaching literature.

Från eld till lågenergilampa : Förståelsen för ljuskällans tekniska utveckling hos elever i årskurs 5

Syftet med undersökningen är ta reda på vilken förståelse elever från årskurs 5 har för ljuskällans tekniska utveckling. Syftet har uppnåtts med hjälp av frågeställningarnaVilken kunskap visar elever i årskurs 5 om ljuskällans tekniska utveckling? och Vilken kunskap visar elever i årskurs 5 om glöd- och lågenergiglödlampan som komponent i ett tekniskt system? Metoden som valts är kvalitativa intervjuer och innefattar totalt tio olika djupgående intervjuer. Under intervjuerna har eleverna fått placera fem olika ljuskällor i historisk ordning, med hjälp av dessa bilder har de fått beskriva den tekniska utvecklingen för att tillslut hamna på elsystemet. Resultatet visar att eleverna har mycket god kunskap om ljuskällans tekniska utveckling och god kunskap om systemet bakom glöd- och lågenergiglödlampan.

Private Equity-bolags styrning av portföljbolag; En fallstudie av värderingsmodellens översättning till olika organisationsnivåer.

The aim of this thesis is to investigate how a valuation model of a Private Equity firm is interpreted into a management control system within the company's different organizational levels. A case study was developed based on the infra-net company Eltel. The management control systems developed by Malmi and Brown (2008)(1) was used to characterize the control systems at each organizational level. The building blocks of this system are planning, cybernetic, reward/compensation, administrative and culture. Miller and O'Learys (2007)(2) theory of mediating instruments and technology roadmaps was applied to analyze the mediating process of the valuation model.

Urinsorterande toaletter : rensning av stopp samt uppsamling och attityder

It is important that the current urine separating systems are evaluated to allow improvements to be made and consequently increase their future propagation. In order to increase the knowledge about urine separating systems this study was made. It included, among other things, measurements of amounts of urine as well as of the composition of urine collected at Nytorgsgatan 4 in the city of Hallsberg. The study was increased after an inquiry that also included the district of Understenshöjden in the city of Stockholm. In the inquiry, the users were asked questions about odour, cleaning of toilets and occurrence of blockages in the urine water locks etc.

Hastighets- och positionsinterface för motorer

The environmental requirements and laws on combustion engine emissions are very tough today andthey will become even more stringent in the future. To achieve these requirements there are highdemands on the control systems for these engines. An improved precision in the measurement of anengine's speed and position gives the electronic control system an even better timing when it comes tofuel injection and ignition. This makes the engine more fuel efficient, reducing the emissions. This thesisis part of a collaborative project between Hoerbiger Control Systems and subsidiaries.

Vad säger bilden?: En utvärdering av återvinningseffektiviteten i ImBrowse

The aim of this master thesis is to evaluate the performance of the content-based image retrieval system ImBrowse from a semantic point of view. Evaluation of retrieval performance is a problem in content-based image retrieval (CBIR). There are many different methods for measuring the performance of content-based image retrieval systems, but no common way for performing the evaluation. The main focus is on image retrieval regarding the extraction of the visual features in the image, from three semantic levels. The thesis tries to elucidate the semantic gap, which is the problem when the systems extraction of the visual features from the image and the user?s interpretation of that same information do not correspond.

Den perfekta informationsspridaren? En komparativ studie av tre organisationers intranätanvändning

This is a comparative study of the use of intranet in three organizations. The organizations are one help organization, one hospital and one business company. The intranet is a relatively new medium and it might still not have been accepted by all potential users, which is a waste of resources both for the individual employee and for the overall organization. It is therefore necessary to investigate if there are any differences between organizations concerning the needs of intranets. Our purpose with this study was to deepen the understanding of the use of intranets as a channel of organizational communication and thereby acknowledge the users´ needs and opinions of the intranet.
