During the middle of the 18th century the development of Toyota Production System, TPS, started in order to streamline the processes. TPS was based on the principles of assembly line production but unlike previous performers Toyota let the manufacturing be constantly affected by demand. At the end of the 18th century TPS was described by Womack and Jones in the book "The machine that changed the world - the story of lean producion" where TPS got the name lean. The principles behind lean is to maximize customer value and eliminate waste which means making products and services more valuable to the customer. 1Lean was for a long time a philosophy and an approach limited to industries and production based companies.

The purpose of this degree project was to build laboratory equipment for a new course in power electronics that starts this autumn 2010 at Uppsala University. The equipment is intended for student labs and it covers the most important areas of the course including rectifying, buck-/boost-converters and PWM-modulation. It is built as one sealed unit where all the electronics are built-in but visible and it has a connection board where students safely can connect the different circuits. The project has advanced from theoretical studies of circuit design, choosing of components and simulations to drawing the printed circuit board (PCB), soldering, case building, final testing and troubleshooting - basically most steps from an early idea to a final product. Measurements on the final product gave about the same results as the earlier simulations of the circuits and the result is overall satisfying..

This master thesis project will describe and evaluate the interfaces between applications and Controller Area Network, CAN, interface boards from different manufacturers. The interfaces have corresponding functions but the usage of parameters is different. The simply communication of sending and receiving messages is more alike than the supplementary functions between the different interfaces. The CAN communication is more controlled by the CAN protocol and is therefore more alike. The evaluation shows differences and similarities between different interfaces and also difficulties and options to translate them.

Wermland was affected by the Spanish flu like the Swedish national average, about a half percentage of Wermlands population would lose their lives to the flu during the autumn 1918. The flu has for many fallen into oblivion. This oblivion is so wide spread that it´s possible to talk about a "collective forgetfulness". The society have selected to remember 1918 for "when the guns went quiet on the western front" and not for the millions who died from the treacherous Spanish flu. The world had already suffered enough from the four years of war that had been fought, thus the victims of the flu would be honored but would soon fade in to oblivion.  When you investigate deeper you get the picture that the national average don´t do Wermland and its cities or rural areas any justice when a large variations seems to occur within regional areas.

The intention of this study was to examine the interaction between authorities. More specifically it had a purpose to look at the ongoing cooperation between social workers and staff of special homes of closed institutional youth care. The sanction system for young offenders? reform of 1999 where young people between the ages of 15-17 who have committed serious crimes, can be sentenced to secure institutional treatment instead of prison, aims to counteract the harm which can result from a stay in prison. The social welfare board in the young person´s local authority and the national board of institutional care shall cooperate during the youth?s placement at the special home of closed institutional youth care.

This is a study about the Swedish liming operation and the Swedish liming officer?s opinions of some aspects regarding ecology, economy and organization. The study objectives was motivated due to the recent changes in manuals for the assessment of limed waters and the suggested changes in decision making and decreased budget for liming. Moreover the anthropogenic acidification effects on the ecology are in many ways complex. Furthermore it was made in order to gain knowledge about the liming officer?s opinions in order to improve the ability to meet their needs regarding the assessment tools and also to investigate if other things can be improved concerning the liming operation.

Due to the growing wild boar (Sus scrofa L.) population in Sweden there has been an increase in wild boar related traffic accidents, damage on cropland, and conflicts regarding the management of the wild boar. Knowing what makes the wild boar reproduce and survive more or less successfully in different geographic areas is an important part of managing the population. According to previous studies the wild boars rate of increase varies from county to county. The aim of this study was to test, on the county scale level, if landscape composition and diversity as well as people and hunter densities might be the reason for this variation. The first hypothesis was that a big proportion of forests and cropland would increase the rate of increase.

The large number of surrendered and feral cats is a big animal welfare problem all over the world. Populations of feral cats arise through a large number of unwanted cats which can lead to surrender of these, through cats allowed to roam free outside which can lead to the owner losing these and through the reproduction that occurs amongst these surrendered or lost cats. One aim of this study is to give an account of this problem. It is however difficult to draw general conclusions about these populations of cats since studies all over the world has been carried out on different types of populations, during different conditions and different periods of time. The welfare of many of these cats is presumably low because they are exposed to risks as disease, starvation, climate, traffic, other animals and humans.

To support, enhance and, in the future, develop the activity within the county councils in Sweden, IT support systems are currently used to a large extent. The need to document is central to the health care organizations and the counties have come a long way in the introduction of electronic patient record systems (EPR). The aim of the EPR systems is to support the care processes and the clinical professions in their work.This is a master thesis in the area of human-computer interaction (HCI), Department of Information Technology at Uppsala University. The aim of the thesis was to describe and compare the five most common EPR systems in Sweden. The comparison will focus on some usability aspects and on how well they support the users in their clinical practice.

During the migration season in 2013 a study on spawning migrating salmon and the effect of water flow on the behavior was conducted of the salmon at the Forshaga hydropower station in the River Klarälven. The River Klarälven with its nine hydropower plants on the Swedish side, constituting migration obstacles for the migrating salmon. Fortum Generation AB has together with the County Administrative Board restored a salmon trap at the lowermost hydropower station in Forshaga, aiming at making it possible for the salmon to swim into the trap, and thereafter be transported by truck past the power plants and then continue their journey to the spawning grounds on their own. Unfortunately, it is believed that the trap does not work as well as it should. In this study, I focused on salmon position in relation to water flow and if the number of salmon that swam into the fish trap differed between salmon with previous experience of the trap (experienced) and salmon without experience (unexperienced).

The study has been done on behalf of and in cooperation with LRF Konsult. The purpose of the study was to try to find out how forest estate buyers valuated different parts of the estate at the time of the purchase and to see if it was possible to identify different trends between different kinds of purchasers. The study is delimited to Västerbotten County and all the purchases were made thru LRF Konsult. The background of the study is that the forest estate purchasers are paying more and more for the forest estates. The prices are often much higher than the net present value which means that they are paying for something more than just the timber value. The study is made with a questionnaire mailed to one hundred forest estate purchasers. Answers got returned from 48 of them.

Under efterkrigstiden har den regionala tillväxten i industriländerna undergått en explosionsartad utveckling. Samtidigt skedde en massiv utbyggnad och förbättring av infrastrukturen. Dessa båda områdes avancemang avslutades abrupt med den globala finanskrisen under 1970-talet. När konjunkturen vände tillbaka och tillväxten tog fart igen var det däremot inte med samma starka stäv som innan krisen. Denna tröga utveckling förbluffade makroekonomerna, som sökte med ljus och lyckta efter möjliga orsaker såsom energipriser, social reglering och regioners näringslivssammansättning.

?Have the young members? of Save the Children Sweden got increased possibilities to influence the organization since the founding of the youth-organization?? The purpose with the thesis is to investigate if the founding of a youth-organization by Save the Children Sweden has led to increased possibility for the young members to influence the organization. I have two research assignments; change since the founding of a youth-organization? politically since the foundation of a youth-organization and how?Did the norms and values in the organizationand Did the organization change I have analyzed protocols from the general assembly between 1997 and 2008 and how the rules in the organization have changed over time. I have also interviewed four board members to get a more diversified view of how the board meetings proceed.

Sitka spruce (Picea sitchensis) is not considered to be a native species to Swedish forests. It´s origin is the pacific coast of Northern America, an area that is dominated by a coastal climate which makes it likely to believe that it would be well suited for growing in the south-west of Sweden. This study aims to investigate the gain in production that can be reached by growing sitka spruce instead of Norway spruce (Picea abies) in the county of Halland. A regression model based on data from forest experiments was produced to explain the gain in production. This model was based on elevation and annual precipitation. The model was then used to create a map layer in arcGIS that shows the gain of volume in comparison to Norway spruce in percent. An analysis was carried out to find what share of the forestland in Halland county that fell into four different classes of production gain.
