A growing issue in the construction industry is how production can become moreefficient by using logistical solutions. Companies can minimize the cost of a project byreducing the time to perform the work.The purpose of this report was to examine the logistics related to pipe trenches forSIAAB. The report's focus has been on solving problems and planning that wouldfacilitate the work of the project Vaksala-Lunda Etapp 3.The case study consists of interviews with SIAAB's employees and an observationwhere the progress of a traditional pipe trench has been documented using checklists.Questions to the report?s case study come from the theoretical part, which is basedon literature on construction management and logistics in general. The observationlasted five weeks and the biggest time-consuming events that affected the pipe trenchduring this time, has received most attention.

This report examines the industrialization of a newly developed household machine on behalf of Technogarden Engineering Resources in Karlstad, Sweden. The report is a part of the final course in the Bachelor Program in Mechanical Engineering at Karlstad University and takes place in spring 2014.An innovator, an investor and a engineering consultant firm have through collaboration developed a new type of gruel machine. The product is in its final stage of construction and is planned to be manufactured in a production located in Sweden, autumn of 2014.To compete against today?s trend in outsourcing manufacturing to low cost countries for better profitability, the industrialization of the gruel machine must be done with a minimum amount of resources in order to become successful, which also describes the problem of this study. Using pre-study material in form of Lean production literature, visiting a successful production site and gathering data from involved engineers a specification was developed which describes what this industrialization must achieve and which requests can be accomplished.

This master thesis was initiated with the aim to answer at what level of installed capacity of wind power in the northern parts of Sweden it would be beneficial to improve the transmission capacity from the northern Sweden. During the process of this work the aim has changed to try and create a model that can be used to analyze how well the hydro power installed in the northern Sweden can even out the quick changes in wind power production.To create a good model of all hydro power in northern Sweden is a very large job, unfortunately too large for a master thesis. This report therefore ends with an extensive analysis of the simplifications that have been made and their effects as well as a list of the future work that has to be done.The model that has been created have shown to be effective and produce good results. The conclusions that can be made is that the northern Swedish hydro power have very good possibilities to balance the wind power production. Only a few cases where water have been spilled even though there has been some free capacity has been discovered.

Background: There have been several reforms within the Swedish educational system since the 1960´s, not only within the elementary school but also within the teachers? education and the school leaders´ educational program.Aim: My aim with this study is to explore if teachers´ expectations and experiences of school leadership have changed since the many educational reforms began in the 1960´s.Method: For this study I have a used a comparative design. By making qualitative interviews with five teachers born in the 1940´s and five teachers born in the 1980´s I have then analyzed the result.Result: Regardless of the 40 years of age difference and the multiple reforms within the educational system in Sweden the result shows that the teachers in this study did not have any clear expectations on their school leaders as they started their careers..

This research looks into the modern revival of opera based on the study of two recent productions of Giuseppe Verdi?s Don Carlo; the first is the 2010 production at the Gothenburg Opera in Gothenburg, Sweden and the second is the 2013 production at Großes Festspielhaus in Salzburg, Austria. The goal is to discover what aspects a contemporary audience can relate to and identify with and why opera is still relevant today. This has been done partly through a semiotic analysis of the visual image (e.g. set, costume and lightning) and partly through a hermeneutical analysis of the themes in Don Carlo.

During the last few years, there has been a lot of debate regarding the price ofelectricity on the Swedish market. According to a recent survey from Sifo, anon-bias governmental institute for consumer research and testing, the priceof electricity is what worries Swedish households the most. An investigationof the eciency of the Nordic power grids inuence on the Swedish spotprice is therefore both relevant and valuable. Three quarters of all electricityproduced in the Nordic region is traded at the Nord Pool Spot power market.This survey examines how much of the variation of the swedish spot pricecan be descried by the variation of the nordic system price and how much iscaused because of ineciencies in the power grid. Primarily, linear regressionwith adjustments for endogeneity and heteroskedasticity has been used in orderto analyze data obtained mainly from Nord Pool Spot and Vattenfall AB.The results show that the variation of the system price can account for all butabout 40% of the variation in the Swedish spot price.

Bakgrunden till denna rapport är det stora antal vindkraftverk som det idag finns planer på att bygga i Sverige. I Jokkmokksliden utanför Malå i Västerbotten påbörjades byggnationen av en vindkraftverkspark under 2010 vilken kommer att bestå av 18 vindkraftverk ritade av en tysk konstruktör. Fundamenten för vindkraftverken är massiva gravitationsfundament där armeringen är särskilt komplicerad att montera och kräver en stor arbetsinsatts. Syftet med denna rapport är att undersöka om och hur man genom att tillämpa nya metoder och planeringsverktyg kan öka produktiviteten och därmed minska arbetsinsatsen. För att uppnå detta har en djupstudie inom Lean Production utförts.

Land management for food production is a fundamental human activity and one of the greatest challenges of the 21st century will be to increase the global food to accommodate a world growing to 10 billion or more people, while undergoing climate change. The increasing temperature and the current and projected increase in concentrations of CO2 lead to concern over possible impacts on agricultural pests. This assay is summarizing the knowledge of weeds in a changing climate in Sweden. Global warming and other climatic changes will affect the growth, phenology, and geographical distribution of weeds. The climate change will also affect the weed composition indirect by causing changes in the agriculture.

The Swedish beef cattle population is growing when the dairy cattle become fewer. The fertility of the beef cows is important for the profitability in beef cattle production. Today there is no genetic evaluation for female fertility in Swedish beef cows. The purpose of this study was to see if calving interval can be used in the genetic evaluation as a measure of female fertility in beef cows. For this purpose the variation in calving interval for beef cows of different breeds and ages registred in KAP was studied.

I den konkurrensutsatta tillverkningsindustrin är det viktigt att ha effektiva processer för att kunna hålla nere kostnader och samtidigt hålla en hög kvalitet för att kunna erbjuda attraktiva produkter till konkurrenskraftiga priser. Lean Production är en produktionsfilosofi vars fokus är att eliminera alla former av slöseri som inte skapar värde för kunden. Ursprunget till Lean Production kan härledas till fordonsindustrin och det japanska Toyota Production System. Systemets tanke byggde på en effektiv produktion för att kunna möta konkurrensen från större amerikanska konkurrenter som kunde dra nytta av storskalsfördelar i sin massproduktion. Ett av inslagen i Toyota Production Systems var att lagra material i nära anslutning till produktionen i så kallade supermarkets.

Given that the end-customer has become more demanding, the retailer has to deliver products according to the market demands, which have forced manufacturing companies to constantly search for new opportunities to reduce costs and improve efficiency. It is, therefore important to choose suppliers that are able to compete with the market demands.The market demands in the textile industry have lead to shorter product life cycles, which have caused manufacturers to deliver flexibility with high technology to compete successfully on the global market. To achieve the market requirements the underlying factor is to be aware and optimally use and control time. New technology can have a major influence in the production development, if the company choose to take benefit of the advantages, by optimal allocation of the internal resources the productivity and efficiency will increase, to accomplish a competitive advantage. One way to achieve this is by investing in a Unit Production System.In our thesis we have questioned what the main driving forces for an apparel manufacturing company is when it chooses to invest in new technology.

Automatic milking systems (AMS) are part of a growing trend in Sweden and the number of milk-producing farms is decreasing rapidly. One main reason for the AMS is its ability to facilitate work for the farmer. The effects of introduction prior to calving have not been documented earlier and farmers are not in agreement, however they seldom see a problem with the introduction. The aim of this report is to find differences between two groups of heifers, where one group is trained i.e. introduced to the AMS before calving and the other group is introduced after calving.

During test flights SAAB uses the data acquisition system COMET 16. The part of the system that receives the signals from the sensors and converts them is called KSM 15. The purpose of this thesis is to develop a data acquisition module on stacked PC/104 modules with a lower production cost. Our work has been divided into one part about analog signal conditioning and a second part with digital filtering and memory management of the sampled data. The analog part, designed of regular components like instrument amplifiers, voltage references, operational amplifiers and multiplexers, adjusts the sensors signal levels for the ADC?s that converts the signals.

Whist is one of the most played card games of the world. Though there have been many studies made in the field of game theory, whist is still somewhat of an unchartered territory. In this thesis some methods to obtain an optimal strategy for whist are discussed. Whist belongs to a group of games called logical games. For this group there exists algorithms which result in an optimal strategy.

Total mixed rations (TMR) and TMR complemented with individual grain feeding to dairy cows are a growing practice in Sweden. This is because the heard sizes of the farms are increasing. Some farmers and farm advisors in Sweden have great knowledge and practical experience of working with TMR. In the same time there are many advisors that do not know how to handle TMR and farms that have a group based feeding of their animals. In this MSc thesis, the knowledge of farmers that use TMR and advisors with lots of experience of TMR are gathered, with the aim to create a guide book for advisors that are about to start or just have started working with TMR.
