Kartläggning av truckflöden på Primary Products : Ur ett Lean Production perspektiv
The Transport division is responsible for the internal transports on Sandvik MaterialTechnology AB. At the moment there is no clear picture of how the straddle carriers aremoving at the division Primary Products and if it is working in a satisfying way. It isimportant to see the whole picture of the transportation flow so improvements can be made.The purpose of this essay is to survey and analyse the truck flow in a Lean Productionperspective. The essay is delimited to only include straddle carriers transportation ways in thePrimary Products division. To survey the truck flow we have used a method called Walkthrough.This means that we have walked thorough the whole production flow andinterviewed some of the employed on the way to get the necessary information.
Självgående renslastare till sockerbetor :
Our greatest interest within crop farming is to grow sugarbeets, that?s why we want to
write about something new in this sector. We heard that a new concept had come to
Sweden so we wanted to find out everything about this machine.
This new technique was a self-propelled cleaning loader for sugarbeets. This machine is
supposed to replace a loader and a cleaning machine when the sugarbeets is going to be
loaded, cleaned and delivered to the sugerbeet factory. The cleaning loader picks up the
sugarbeets with rollers from the pile, which is placed close to the road.
Trycksättning och dimensionering av brandhiss för berganläggning
This thesis deals with the design of a combinated rescue-, personal-, and firefighting elevator for a nuclear waste storage facility to be constructed by the client SKB, Svensk Kärnbränslehantering AB. SKB:s mission is to dispose of all nuclear waste from all swedish nuclear power plants. The storage facility will be built in the rock 450 m under the surface and will consist of several kilometers of tunnel where capsules containing the nuclear waste will be placed. It will also hold a central area which contains spaces necessary for the operation and construction of the facility, such as elevator hall, storage hall etc. The facility will have two ways of access: a vehicle ramp and an elevator shaft.

Kemisk stabilisering av gruvavfall från Ljusnarsbergsfältet med mesakalk och avloppsslam
Mine waste from Ljusnarsbergsfältet in Kopparberg, Sweden, is considered to constitute a great risk for human health and the surrounding environment. Some of the waste rock consists of sulphide minerals. When sulphide minerals come into contact with dissolved oxygen and precipitation, oxidation may occur resulting in acid mine drainage (AMD) and the release of heavy metals. The purpose of this study has been to characterise the waste material and try to chemically stabilize the waste rock with a mixture of sewage sludge and calcium carbonate. The drawback of using organic matter is the risk that dissolved organic matter can act as a complexing agent for heavy metals and in this way increase their mobility.
Framgångsfaktorer för rundvirkesåkerier i Mellansverige :
Generally, the economic health of Swedish roundwood truck transport companies has not been good. Profitability is important for maintaining the stability in the transport business, which is a condition for long-term transport planning in the forestry sector.
The scope of this study was to identify probable factors influencing the profitability of roundwood truck transport companies and quantify the influence of these factors on economic results.
The study was carried out at a major roundwood truck transport organisation in mid-Sweden and was implemented in four steps. In the first step economic results from the haulage contractors were collected and a random sample was taken from accounted net margin for the account year 2005/2006. In the second step hauliers were interviewed to identify probable success factors. At the third step data for identified factors were gathered through a questionnaire.

Grundvattnets geokemi vid Gladhammars gruvfält, Västervik. Effekter av äldre tiders kobolt- och kopparbrytning
The municipality of Västervik, with support from Envipro Miljöteknik AB, is carrying out a main study of the minefields at Gladhammar. Mining of iron, copper and cobalt under different periods from the 16th century until the end of the 19th century has led to discharges of metals to the lakes situated downstream. The aim of the main study is to investigate the possibilities to reduce the environmental load on the surrounding ground and water caused by heavy metals from the mine. The present report is a part of the main study. The aim of the work is to investigate the geochemistry of the groundwater.
En intuitiv & lättillgänglig flyktmask för gruvmiljö
I have always lived around mines and around people working with mines. They are a natural part of my life and, inevitably, a great interest of mine. When time came to make a decision for a degree project, focusing on the mine context felt as natural as breathing.In LKABs underground mines, safety in fire accidents is a great priority. Of outmost importance for the escape is to have a personal gas filter for filtration of smoke and/or gas. My design project resulted in a concept which is aimed at shortening the user journey from the start of the accident until the user has applied the personal safety solution and is ready to escape.Throughout the project I?ve been working with a context which is heavily regulated, and all problems are serious, important ones.

Utveckling av provmetodik för HVAC på lastbil : Klimatprovning i klimatvindtunneln CD7
The issue about how Scania shall perform HVAC tests in the climatic wind tunnel CD7, which Scania is about to complete by year 2013, has resulted in four test methods for truck HVAC and also a test method structure. The test methods have been chosen to focus on sun, snow and rain simulations. These are adapted and developed according to what should be tested and to what can be tested in CD7, which has been the object. With CD7 different climates can be simulated in a controlled environment for complete truck level, from desert with high sun load to arctic cold and snow.The test methods represents a basis to start from, for designers and test engineers which make the testing more repetitive as well as time eventually can be saved. Before the test methods can be applied they must be verified as they are based on theoretical and empirical assumptions.

Effects of Driver, Vehicle, and Environment Characteristics on Collision Warning System Design
The purpose of the present study was to examine effects of driver, vehicle, and environment characteristics on Collision Warning System (CWS) design. One hypothesis was made that the capability of collision avoidance would not be same among a driver, vehicle, and environment group with different characteristics. Accident analysis and quantitative analysis was used to examine this hypothesis in terms of ?risk? and ?safety margin? respectively. Rear-end collision had a stronger focus in the present study.
