Skapandet av ett integrerat ledningssystem
To be able to compete on the market environmental Management System has become an important part of operations work. However, many companies still haven?t implemented an environmental management systems due to lack of time and the high costs. One of the companies with this problem is Falu Bildemontering. Their goal is to accredited according to the ISO 14 001 certificate.
Utveckling av golvlucka för hoppgropssystem i kommunal idrottshall
In this thesis a concept for floor hatches for foam pits has been developed. Since there is an existing solution that is powered by hydraulics and is expensive, the goal was to develop a cheaper solution, as simple as possible.A number of different concepts were developed and evaluated. A concept with five sections that are pulled to the side and stacked on each other was chosen as it was thought to have the lowest risk of crush injuries and to be easiest to manage and control. In the opening behind the foam mattress a lifting table is placed to regulate the height of the stacked sections.To be allowed to be installed in the floor of sports halls the sections must be dimensioned according to the construction standards for these types of buildings. Different dimensions of beams in steel and wood materials were evaluated and of those, who lived up to the requirements of the standard, a concept was chosen.
Skarven : ? Produktutveckling av en oljedimavskiljare
This thesis is a product development project that was performed at Alfa Laval Tumba AB. In the past Alfa Laval have manufactured gas separators for engines where gas flows were cleaned from oil. A new business area for this kind of technology has shown to be the manufacturing industry where oil mist has to be separated from the vented air. Therefore a new and bigger design is needed to be able to handle the greater gas flows. A product like that would be a strong competitor on the market when the maintenance would be low in comparison to today?s equipment.During the project several concept suggestions were developed using customer interviews and research as input.
Studie av planerings- och produktionsprocess i sågverksbranschen
The sawmill industry is a relative fragmented industry that is in an economic upswing andwith a hard competition. The customers have high demands on their suppliers and the highcustomer demand make it necessary for the companies to make a streamlining in planningand production. For that reason it is very important that the planning- and productionprocesses aren?t to complex and with a simple structure.The purpose of this report is to study and map out a marked out part of a planning- andproduction process, from adjust works to final delivery, at a company in the sawmill industry.Different methods have been used for the report, among others interviews and subordinatedmaterial.We have mapped out a marked out part of the planning- and production process at theCompany. This part we have studied, and we have analysed the process it self and otherthings connected to the process.We see the planning- and production process in the Company as complex.
Varannan vecka : En kvantitativ studie om samband mellan socioekonomisk grupp och barns växelvisa boende i Sverige.
Syftet med den här uppsatsen är att undersöka om det finns ett samband mellan växelvis boende och socioekonomisk bakgrund. Uppsatsens frågeställning är hur föräldrarnas socioekonomiska bakgrund påverkar sannolikheten att barnen har ett växelvis boende, konstanthållet för relevanta kontrollvariabler. Detta kopplas till den andra demografiska transitionen samt till de socioekonomiska följderna för barn. Datamaterialet som använts i uppsatsen samlades in åren 2001-2003 och kommer från Statistiska centralbyråns Barn-ULF. Utifrån det har bivariata och multivariata analyser skapats genom logistisk regression.I resultatet framgår att det finns ett samband mellan växelvis boende och socioekonomisk grupp.
Kan man identifiera de karaktäristiska dragen hos stop-motion och applicera dem inom 3D-animation?
For any animator either working in stop-motion or 3D-animation the knowledge of the first animation techniques are most important. For it is based on these principles that animation today can create such vibrant characters. With the extreme development 3D-animation has undergone the last twenty years it is easy to lose track of the old ways. But with this thesis a hope to show that it is these old ways that will take animation to its next stage. My aim with this thesis is to find out if it is possible to identify the characteristic features of stop-motion and apply these onto 3D-animation with purpose to create a more expressive style of animation.
Modellering och reglering av ureainsprutning på kraftvärmeverket FTG
The aim of this thesis is to improve the control of urea injection at the combined power and heating plant Framtidens Gärstad (FTG). Tekniska Verken i Linköping AB is the owner of the plant.The FTG plant consists of a boiler where garbage combustion is done. From the combustion nitrogen oxides are emitted. These nitrogen oxides are hazardous to the environment. To reduce the nitrogen oxides, injection of urea into the boiler is used.
Kan överutbildning förklara en del av könslönegapet? : En kvantitativ studie av vilken betydelse matchningsprocessen på den svenska arbetsmarknaden har för könslönegapet
Denna uppsats syftar till att studera hur könslönegapet, med kontroll för sedvanliga humankapitalvariabler samt sektortillhörighet, påverkas av matchningsprocessen på den svenska arbetsmarknaden. Detta har gjorts med hjälp av linjär regression och metoden minstakvadratskattningen, även kallad OLS (ordinary least squares). Den data som ligger till grund för undersökningen är tvärsnittsdata från Levnadsnivåundersökningen år 2010. Det teoretiska ramverk som studien tar avstamp i är den klassiska humankapitalteorin vars antagande är att utbildning är en investering för individen som höjer dennes produktivitet och därigenom leder till en högre framtida lön. Dock har tidigare forskning visat att utbildningens avkastning står i relation till arbetets utbildningskrav, där en överutbildad person får avsevärt lägre avkastning för de år som dennes utbildning överskrider arbetskravet i jämförelse med en rätt matchad person.

This paper aims to analyze how child restraint systems (CRS) in cars should be positioned to protect children at the ages 1 to 5. The study is preformed in co-operation with the Swedish insurance company Folksam. Data from Folksam´s database on car crashes in the years 1999-2004 is being used in this study. Every child in the ages 1 to 5 was searched for in the database, which resulted in 184 observations. To perform the analysis, categorical data analysis is suitable.
Language Manager Version 2.0
This report describes an examination project made for the IT consultingcompany Sogeti. The purpose of the project was to develop and modify the translation tool Language Manager (LM) built by Sogeti to be used for translating applications. Employees at Sogeti considered some disadvantages with Language Manager, version 1.0 which among others was that language files for projects were saved at two locations. Partly in resource maps among with the source code of the applications and partly in a database. This was dual work for employees at Sogeti and it also caused redundancy inthe system.
En jämförelse av beteende mellan vävande hästar och två icke vävande hästar under liknande förhållanden :
Today we keep our horses in a way that is easy for us humans but may not always be the most optimal way for the horse. Often the housing of the horse prevents the horse from performing behaviours that they have natural needs to perform. It is not unusual that animals that can not adapt to their environment develop abnormal behaviours. Many of our stabled horses therefore develop some kind of stereotypic behaviour. This study was made in purpose of comparing the behaviour of a weaving horse to two non-weaving horses under similar conditions, where one of the horses was stabled next to the weaving horse and the other horse was stabled further away in the same stable.
Seven weaving horses were included in the study.
Inflyttning i Stockholmsområdet - En regressionsanalys av variabler som påverkar inflyttningen i Stockholmskommunerna.
Undersökningen handlade om att ta fram en modell med variabler för att avgöra om det finns några variabler som påverkar inflyttningen till en kommun i Stockholmsområdet och i så fall vilka dessa är.Undersökningen gjordes med hjälp av regressionsanalys av variablerna och metoden som användes var stepwise regression.På så sätt erhölls koefficienterna till modellen och med hjälp utav dessa kunde man tolka om variablerna hade positiv eller negativ inverkan samt testa huruvida väntevärdet skulle kunna vara negativt eller positivt med hjälp av hypotestest med konfidensintervall.Vid tolkning av variablerna så erhöll man att dem flesta variablerna betedde sig enligt dem hypoteserna man slagit fast vid tidigare.Det visade sig att dem flesta utav variablernas väntevärde vid 95% konfidens intervall faktiskt låg inom ett område där det kunde anta både positivt och negativt tecken.Dessutom gjordes residualplottar för att undersöka hur bra modellen var och om det förekom några mönster i variansen, det slogs fast vid observation att inga mönster förekom i plottarna.Slutsatsen man kom fram till att även om vissa variabler betedde sig enligt dem uppskattade hypoteserna så tar modellen inte hänsyn till en del faktorer som kan ändra inflyttningen, samt att det finns fler variabler som kan ha större betydelse för hur folk väljer sin hemkommun..

Do CEOs Get Paid for Performance?
Agency theory describes the conflict of interest between the principal (stockholders) and the agent (CEO). Aligning the incentives of executives with those of the owners is the most direct way to mitigate the agency problem. If there is no meaningful link between CEO compensation and company performance, it is doubtful that the large sums of assets in public corporations are being managed efficiently. In theory the solution is simple reward the CEO when shareholders wealth increases. The purpose of this paper is to investigate if there is a relationship between company performance and CEO compensation among Swedish companies, in materials and information technology industry.
Keep it real and Quick : En undersökning om hur företag bör kommunicera mot 80-talister
Today we live in a more or less globalized society where borders do not pose the same obstacle as before. This is why it is interesting to examine whether different countries have similar views on how to communicate with a specific audiencePurpose: The purpose of this thesis is to use the data gathered to inform businesses with information. The information can then be used to assist companies when it comes to advertising, the design of messages and the choice of media channels when communicating with people born during the 80?s. Furthermore, the investigation intends to find out if there really is a global market for people born during the 80?s.Method: The authors believe that a purely quantitative or qualitative approach is not appropriate.
