Syftet för det här examensarbetet var att praktiskt reducera ställtiden på enbefintlig produktionslinje på Ruukki i Halmstad. Vid tiden då författarna togkontakt med företaget var den nuvarande ställtiden alldeles för lång och långtifrån optimal. I samband med projektets start gjordes det ett antal avgränsningaranpassat till den tiden som fanns tillgänglig.Tillvägagångssättet och metodiken till lösningen bakom ställtidsproblematikenföljer Shigeo Shingos Single Minute Exchange of Die (SMED), där har författarnautfört analyser i form av iakttagelser och tidtagning. Upptäckterna som gjordesunder analys samt implementering var att även om SMED är en direkt metodik förställtidsreduktion finns det andra faktorer som kan motverka implementeringensamt dess goda resultat. Dessa faktorer som påvisades under projektets gång varbland annat de mänskliga aspekterna och den bakomliggande företagskulturen iorganisationen.

This Master thesis was written for Lantmännen Agroetanol in Norrköping concerning the layout of their finished goods inventory and unloading of feed after introducing a new product mix. Lantmännen Agroetanol has two production lines which produces feed. Both lines lead to six silos, used as inventory of finished goods. The feed from the two production lines differ in terms of quality, where as Lantmännen Agroetanol wants to separate their finished inventory in order to charge a higher price, by selling the better product as a premium. With two different feed products the yearly revenue is expected to increase which motivates a research about the current capabilities and necessary changes to be made in the factory.

SUMMARYInventory of raw materials holds an important role in companies within the manufacturingsector. The inventory works as a buffer that secure the supply of materials to the productionunit. The aim of the inventory is to ensure that the company is able to meet the customers?demands despite fluctuations and variations in the material flow. The size of the warehouseand the layout are physical limitations for the quantity of articles that can be stored.

Burkina Faso as well as most sub-Saharan African countries struggle with providing food for a fast growing population. The dominating farming system is agroforestry parklands. Agroforestry parklands can broadly be defined as areas where scattered trees occur on farmlands as a result of selective clearing. The presence of trees in crop fields may in the long term have a positive effect on the production of annual crops. It is commonly discussed, but not proven, that the presence of trees leads to increased groundwater recharge due to higher infiltration capacity of the soil.

The purpose of this work, has been to examine how different actors in the Swedish eco movement and the Swedish forest industry looks at Sweden?s forest policy statement, which claims that environmental goals and production goals should be equal in Swedish forestry. By assembling focusgroups with participants from the Swedish eco movement and the Swedish forest industry, we look at if these participants consider the Swedish forest policy goals equal or not. Conflicts do occur between the two forest policy goals, but also between those and others of Sweden?s environmental goals.

Atlas Copco Tools develops and manufactures handheld industrial tools. Heat and surface treatments are used to provide the tools with certain properties. There are no routines for the choice of treatment or for how to specify treatment on drawings. Production documents that are sent for production abroad may not be clear enough. Some treatments are known as trademarks and there are no instructions for how to specify these on drawings and in CAD-models.The purpose of this master thesis work is to create recommendations for the procedure of choosing heat and surface treatment.

The aim of this study was to develop a load prognosis model for Uppsala district heating system to be used as a tool for heat production optimization. The methodwas to build three models for the different customer types; housing, industry andoffices and then scale them for the total system using data from Uppsala districtheating system. The heat load consists of two parts, one that is temperaturedependent and one that is dependent of the social behavior of the customers. Thetemperature part was modelled with an ARX model using an outdoor temperatureprognosis as input signal. The social behavior part was modelled using the mean ofthe social behavior from some days before and additionally by distinguishing betweenweekdays and weekends.

Habituation to an automatic milking system (AMS) for cows in their first lactation differs from habituation to other milking systems. In AMS the cows are supposed to visit the milking station (MS) voluntarily. The milking takes place individually during the whole day, except when the milking system is cleaned. Milking is carried out without any human survey. The aim of the study was to describe the cow?s introduction in AMS in their first lactation.

Scania is among the leading companies in the heavy vehicle industry. Scania also assemble engines for their trucks and buses, as well as to external marine and industrial applications. Wrongly assembled parts leads to quality problems, which makes it important to secure that the assembly is correct. To do this Design For Assembly (DFA) is used to describe how parts should become easier to assemble. Scania?s production unit for engine assembly has had a working method for DFA in the shape of a checklist, which is not used.

AbstractA prerequisite to be able to use semi-natural pastures in an optimal way is knowledge about their conditions and properties. One thing to consider is the amount of herbage mass that can be produced during one season on different types of semi-natural pastures. That knowledge makes it easier to choose which type of animals and how many you are able to have in each paddock to maintain a high biodiversity and achieve the desired production of the animals at the same time.This study was performed in nine different semi-natural pastures around Uppsala. The paddocks were already mapped with regard to different vegetation types. Exclosure cages were placed on previously fertilized, mesic, dry, shaded and wet vegetation.

One of the most discussed archaeological subjects is the neolitisation, and the start of a neolithic lifestyle which is characterized by several significant events. The traditional view has been that settled people were cultivating and breeding, but this picture has been questioned and changed in later years. The development is principally based on two models; that already neolithic people immigrated and took over, or that the new lifestyle gradually developed out of the existing cultures. Southern Scandinavia was characterized by a settlement pattern with permanent settlements which were complemented by temporary special settlements, but in time more domestic settlements originated. On the British Isles the settlements didn´t consist of permanent agricultural settlements but instead did the people here move freely between several short term settlements.  .

As I recently started to record in a studio, I almost immediately came to the conclusion that getting the right sound is not easy. I became curious about my recording procedure. What did I do wrong? How to place the microphone? Use of equipment? How is it possible to modify the sound afterwards? Are there any special methods that are commonly used among producers and/or guitarists? My thoughts ended up in a question ? What do producers and guitarists think of the guitar sound during a recording session in relation to the final production? In my research I interviewed two producers and two guitarists about guitar recordings. The results show that the quality of the guitar sound is in relation to production and style of music.

Organic rearing of broilers is not a large production in Sweden. In order to create a sustainable yet efficient production of organically produced poultry meat, at a price that the consumers are willing to pay, much more knowledge is needed. It is therefore important to do more research on organic broilers under Swedish conditions. This report is aimed to be a base for further studies. In the study 2000 broilers of the hybrid Ross 308 divided in to two equal groups. The broiler hybrids that are used in Sweden are selected for a high growth rate and are normally slaughtered at the age of 5 to 6 weeks, with a slaughter weight of 1.7-2 kg.
