Visuell informationshantering i tunga fordon : Behovsanalys och förslag till förbättringsåtgärder

The flow of information in road vehicles intensifies as new techniques develop. Informationsources such as cell phones, navigation equipment and radios demand the driver?s attentionwhile he or she must stay focused on the road to perform a safe driving. Today the visualinformation inside the vehicle is mostly located on the dashboard, which forces the driver tolook down when shifting attention between the environment outside and the informationinside the vehicle. One way to avoid this is to useHead-up Display (HUD), a technique thatprojects information in the visual field of the user.This master thesis has been performed in cooperation with Scania CV AB, a world leadingtruck producer.

Design av förhandlingsstöd - En fallstudie inom radiologisk verksamhet

Recent developments suggest that private and public companies are moving towards a more service-oriented business. Service orientation means that hardware is often sold in packages with service agreements, which makes the investment more difficult to assess. The challenges that arise will be to assess the value of the overall package, the information needed to make informed decisions and the operational requirements in combination of hardware, software, support agreements, training and more. The paper therefore aims to examine how decision makers can evaluate the benefits of these investments and obtain a stronger base to make better decisions. There is within the area of radiology in the region of Västra Götaland a pronounced need for a better flow of information regarding medical equipment and related service agreements.

Finns det förbättringspotential inom vårdhygien på isoleringsavdelningar för smådjur i Sverige?

Aim: The aim of this paper was to investigate whether scientific evidence exists to improve, of students? perceived, insufficient infection control in isolation facilities in companion animal hospitals in Sweden. Material and methods: A question was emailed to the students in the last year of the animal nursing program at SLU in the spring 2012 to get their view of perceived insufficient infection control. A literature study was thereafter preformed using the search engine Web of Knowledge. Results: The students reported several perceived shortcomings which were divided into five categories: basal hygiene, isolation routines, cleaning and disinfection, patient flow and other. Studies supporting that the shortcomings perceived by the students also exist in human health care and to some extent in animal clinics and hospitals were found. Furthermore, scientific evidence that improved hand hygiene, glove procedures and cleaning and disinfection reduces the risk of nosocomial infections in humans was reported. Conclusion: There is not a lot of research performed in the area of infection control in animal nursing.

The demand for shorter lead-times and increased delivery reliability puts pressure on companies to provide more efficient logistic services. One strategy to deal with this demand is by outsourcing logistics to a third part. The development of logistics information systems enables increased control over business supply chains. This is why Green Cargo aims to create a Logistics Control Tower (LCT) solution to provide it?s customers with better information with higher availability.

Markering och risning av basvägar inom slutavverkningstrakter : en intervjustudie hos maskinförare och planerare

In an attempt to prevent ground damage and to reduce harvesting costs, StoraEnso's districts Värmbodal and Fryken, selected a number of final felling areas where the base roads have been marked by planners in the districts. The parties involved in the experiment are mainly planners, harvester operators and forwarder operators. The purpose of this paper is to determine the findings of this trial and to find cost savings or lost revenue. This has been done with a sample of interviews from the involved parties who logged the chosen felling areas. Literature about the interview process has been used to facilitate data collection, interpretation and analysis of the material. If we look at profitability based on assumed income and expenditure, revenue per MWh would be 63 SEK.

Avbördningsekvationer för sjöar utan vattenföringsmätningar

Stage-discharge equations for lakes without disharge measurementsSimon AnderssonIn 2015 all lakes, rivers, coastal water and groundwater should be of good ecological statusaccording to the water framework directive from the European Union. In the process ofimproving the quality of Swedish water bodies, knowledge of where problems occur isneeded in order to utilize the resources optimally. The ability of lakes to store water is animportant factor since it controls the flow of water through the country. A stage-dischargeequation is a mathematical relation between discharge from a lake and its water level. Bybetter understanding of stage-discharge equations for lakes, their storage capacity can bedescribed better in hydrological models.This master thesis aims to evaluate methods for determining stage-discharge equations forlakes where a variable amount of field measurements is available.

Kassationer på ett livsmedelslager - Effektivisering och kvalitetssäkring av processen för intern kassation i enlighet med Lean Production

Today's fierce competition means that companies constantly must develop their business and internal processes. Focus on processes and continuous improvement is something that characterizes Lean Production which ICA logistics are applying with their concept Leading Logistics. Standardized routines for handling damaged gods were insufficient at the ICA distribution center in Kungälv. Handling and registration of damaged gods were not performed uniformly, resulting in problems with controlling and monitoring the process.The purpose of this thesis was to analyze and make recommendations how the process of internal handling of damaged gods could be improved. Therefore a comprehensive understanding was needed of the entire material flow through the warehouse and important quality aspects such as product safety and delivery reliability.The methods used are literature reviews, interviews and observations to produce a comprehensive process mapping of the current situation at the distribution center.

Renoverings strategier på befintligt fastighetsbestånd?fyra fallstudier om allmän nyttiga fastighetsbolag

Today  Real  estate  companies  face  the  challenge  where  extensive  renovations  on  existinghousing built before 1980 must be performed. Conditions have changed and the housing need performance-­?enhancing measures that meet today's quality. With a current renovation rate,  it  would  take  30  years  to  meet  the  renovation  needs.  The  renovation  rate  must therefore rise dramatically, which requires the real estate companies to act consistently in accordance with commercial principles and in an economically, socially and environmentally responsible way.The  paper  discusses  renovation  strategies  in  four  municipal  housing  companies  in  the Stockholm  suburbs.  The  report  includes  surveys  of  four  ongoing  renovation  projects; Fastighets AB Förvaltaren in Sundbyberg project Hundloken 3, Stiftelsen Signalisten in Solna project Ritorp, Sollentunahem in Sollentuna project Svalgången och Väsbyhem in Upplands Väsby project Dragonvägen. The main purpose of this study was to analyze the practices of redevelopment projects.

Avskiljning av ammoniumkväve och fosfatfosfor i reaktiva filtermaterial : skak- och kolonnförsök

In Sweden more than 400 000 private households have not yet sufficient wastewater purification. These effluent is considered as an increasing problem and many onsite purification methods have been studied. In this investigation, the method of reactive bed filters have been tested by column and batch experiments. Five different kinds of filter materials with reactive surfaces have been studied concerning their capacity to absorb ammonium and phosphorus from wastewater. The materials that were examined are Filtra N, wollastonite Filtra P, blast furnace slag and Polonite®.

Bevattning av lagrat virke vid svensk skogsindustri : omfattning och miljökonsekvenser

Most of the saw and pulp industries have stored wood nearby their production, the main reason is to have a continuous wood flow to the production. Wet storage of wood is of great importance to keep the wood quality. Without water sprinkling the risk of drying outand decomposition through biological activity increases significantly and will result in a negative effect on future production and quality. One drawback of wet storage of wood is the leaching of chemical substances into the surrounding recipient. The log yard run-off contains phosphorus, nitrogen, phenols and organic substances. These substances can cause problems for the surrounding environment. The main objective of this project is to gain an understanding of the wet storage used by the Swedish wood industry and estimate the environmental consequences that run-off water will have on the recipient.

Förändringar av arbetssätt vid implementering av BIM : En kvalitativ studie av två traditionella projekteringars arbetssätt och tid- och resursplanering samt vilka förändringar som är nödvändiga vid implementering av BIM

I en rapport från 2005 framtagen av FoU-Väst i samverkan med Centrum för management i byggsektorn (CMB) konstateras att en betydande del av allt slöseri i byggsektorn är kopplat till fel och konsekvenserna av dessa, med andra ord felkostnader. Studien visar att felkostnader står för cirka 10 % av ett projekts produktionskostnad.   Byggsektorn står nu, år 2012, inför förändringar i sitt arbetssätt för att minska antalet fel, öka kvaliteten och effektiviteten. BIM ? Building Information Modeling, möjliggör ett smartare sätt att skapa, använda och förvalta information genom hela bygg- och förvaltningsprocessen. BIM ger möjligheten att anpassa informationen i varje delprocess och därigenom effektivisera arbetet.

Bankernas bedömning av lantbrukskrediter : en jämförelse mellan olika branscher

The agricultural sector has historically seen stable prices and a relatively constant demand for its products. Companies within the sector have generally had few loans and large sums of money tied in assets. The profitability of the companies has on the other hand been low. Together these circumstances have determined the creditors? demands on the companies within the sector and have formed the rules and regulations that exist today.

CFD simulering av en fyrtakts Otto motorcykel motor

This thesis deals with the numerical 3D simulation of a four stroke, spark-ignited, internalcombustion engine, which is mounted on a high performance motorcycle. The work, carried outin collaboration with Politecnico di Milano and MV Agusta, focuses on the simulation of theintake, compression and expansion stroke, including combustion simulation, using an opensource CFD code.Simulation of internal combustion engines offers a great challenge in the field of CFD research.Moving boundaries of the solution domain, caused by the motion of the piston and valves, leadsto deformation of the computational grid, with decreasing quality of the solution as result. Basedon this, a previously developed mesh motion strategy was employed where a number of meshesare used to cover the whole simulation cycle. Within each mesh interval the internal cell pointsof the mesh are moved to account for the boundary motion of the piston and valves. This strategywas previously applied to simplified geometries as well as real engine geometries.

Saab Dynamics is a company operating in the defence industry where competition is tough. This necessitates new ways to increase efficiency in the company, which is the basis for this thesis. Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines.

Företagsförvärv : En studie av onoterade små och medelstora företag

Sweden is facing a shift in generation where the people born in the 1940s are starting to retire which results in consequences. Before the year of 2013 more than 180 000 companies will have to change owner. A study indicates that the majority of all Swedes in the age of 18-70 can consider becoming company owners.Only ten percent of the companies for sale will reach the company broker and another 15 percent will be mediated by legal experts and accountants. This means that 75 percent of the companies for sale will not be available for the public market. As a potential buyer this is a problem.
