The project was performed at SiemensIndustry Drive Technologies with theobjective to provide actual values forthe energy savings potential withinSiemens scope of practice.In Sweden the electrical drives standfor about 30 % of the total electricityconsumption and about 60 % of theelectricity consumption within theindustry. During the pre-study phaseelectrical drives with pump applicationswere identified as large energy users.Because of this a case study at one ofSiemens customers, Stora Enso Fors wasperformed. The system that was evaluatedduring the case study was a throttledsystem with a centrifugal pump forpumping pulp.The results yielded that a saving ofover 50 % could be achieved by replacingthe throttle valve with a variable speeddrive, a frequency converter. Thepayback period was two years and twomonths and the present value for thetotal life cycle cost of the variablespeed system was 662.566 SEK lower thanfor the throttled system. As aconsequence, Stora Enso Fors is advisedto invest in a frequency converter forregulation of the system.The general conclusion is that a focuson system efficiency is the mostimportant factor in energy efficiencyprojects and that the system regulationmethod has a large impact on the overallsystem losses and hence its efficiency.Energy efficiency potential forthrottled systems with centrifugal pumpsis large and significant economicalsavings can be made through investmentswith short payback time..

The construction industry has been heavily criticized in the past few years for its development of productivity compared to the manufacturing industry. In 2009 the Social Care Center developed a report that treated och criticized different errors within the construction industry. For instance competence, construction errors and performance had showned bad results which had to be improved. A common sentence within the building industry is that ?every project is unique?. Today it?s common for a construction company to have costs for material and services which exceeds two-thirds of the Total cost.

Active sensors are used a lot in the society and industry, for example to gain better control over processes or to get proximity sensing features in different products. Within industry there is great interest in developing safe automation products that can be controlled with high accuracy but still at a low cost.The goal of this project is to develop a prototype of a non-contact rangefinder that measures distance using infrared light. The sensor is to be used for various applications in industries with relatively high accuracy and be compact, but at a low cost. By implementing a rangefinder into a product, more accurate detections of an object?s presence can be done.In this project a new distance sensor, EPC600 from ESPROS, was used.

The cost of construction projects have increased during the past few years. Different actors in the construction industry work together to advocate various measures to mitigate these cost increases. One of these measures is to try to improve the efficiency in the phase of production. By striving for a kind of standardization with a constant quest for improvement, the productivity can increase while the costs of production fall.For this thesis has a case study been conducted at the construction company JM AB which is seeking this. They call the approach structured production and have implemented various measures to achieve a more productive output.Based on information from reconciliations, the cost and the spent hours of craftsmen have been analyzed at the company where the case study took place.

Construction companies in Sweden have for recent years seen an increase in the numbers ofwarranty complaints associated with the market of resident buildings and the cost for this hasbeen measured to over 1.2 billion SEK per year. Working with poor quality cost as a way ofcreating insight about defects within the company?s processes is a method developed and usedby the manufacturing industry for decades, but have not yet reached the construction industry.This study has been performed in collaboration with a Swedish construction company, wherethe author has been stationed at the aftersales division for residential buildings. Owing tocircumstances, this published report has been made anonymous regarding the company whowill further on be namedthe Company. The Company is aware that warranty claims producegreat costs and has requested a way of putting cost and cause to specific claims in order ofreceiving a more specific cost view and to make the reuse of knowledge more efficient.

The Swedish production of biogas was 1,5 TWh 2011. About half of the production was used as vehicle fuels. The cost for upgrading biogas depends on the size of the biogas plant and its gas production. If the gas flow is low the cost will be high. However, further development of existing upgrading technologies or development of new ones, have good potential to decrease the upgrading cost for small scale biogas plants.

Introduction: Sex and education level has demonstrated effects on health status.Osteoarthritis is a widespread disease that causes reduced health-related quality of life and isthe most common reason for total hip replacement. Osteoarthritis was ranked as the 11thhighest contributor to global disability as reported in the Global Burden of Disease 2010.Aim: The aim of this study was to explore how sex and education level together affectedhealth-related quality of life after total hip replacement. The aim was also to examine whatdimensions of EQ-5D that changed.Methods: The study is a prospective observational study with a quantitative approach. Dataconsisted of education level, obtained from Statistics Sweden (SCB) and health-relatedquality of life before and one year after total hip replacement from the Swedish HipArthroplasty Register (SHAR). Health-related quality of life was measured with astandardised instrument, the EQ-5D, and the study population consisted of 39,141 patients.Results: Womens? EQ-5D-value, before and one year after surgery, were lower in alleducational categories compared with men.

During the transportation of logging residues (LR) the material´s low density is a problem that results in low use of pay-load capacity. Comminution or compression of LR are possible methods to increase pay-loads. In the present thesis studied a bundling machine which was mounted on a truck chassis, and the subsequent transport and crushing. The truck bundler created bundles that were larger and longer than other bundling equipment on the market. The objectives were to determine the total time consumption and its allocation over work element and machinery, to measure dry matter (DM) content of green and brown LR-bundles.

What does the Swedish church Västerås stand for today according to the employees and how do they want to profile themselves to the target group? What image and what expectations does the target group have of the Swedish church Västerås? How can the Swedish church Västerås communicate uniform, with the intent to create mutual value with the target group?The purpose of the study is to make recommendations to the Swedish church Västerås for their prospective communication plan by examining their profile and target group's image and expectations of the organization. The study also aims to examine how the Swedish church Västerås can communicate their brand uniform.The study applies a qualitative research with deductive approach. Data were collected through semi-structured interviews with a sample of the employees and focus groups with a sample of the target group.Better match between profile and image means that SkVs employees better understand the organization and can communicate more uniform which leads to a stronger brand identity. If SkV understands what is relevant for their target group, they can reduce the Total cost of customer delivered value and thus increase the total value.

När en kommersiell hamn byggs ut fordras omfattande muddringsarbete för att säkerställa ett brukligt djup för sjöfart. Då stora delar av muddermassorna ofta är förorenade av tungmetaller och miljögifter krävs särskilt omhändertagande av dessa. Traditionella omhändertagningsalternativ består av att deponera massorna på särskild avsedd plats på land eller tippa till havs, något som inte tillåts för förorenade sediment. En relativt ny metod är stabilisering/solidifiering (S/S) som innebär att muddermassorna behandlas med ett bindemedel för att sedan kunna användas som fyllnadsmaterial i exempelvis kajkonstruktioner. Dessa alternativ behöver noga vägas mot varandra med hänsyn till ekonomiska och miljömässiga aspekter.

The aim of this study is to examine possibilities and barriers for an introduction of electric vehicles in Sweden. The study has an interdisciplinary approach and thoroughly examines the essential topics which influence the future of the electric vehicle. The study reaches from answering the question on why electric vehicles lost the game to petrol cars in the early 20th century, to sketch how the difference in Total cost of ownership will be between electric vehicles and petrol cars for the coming 20 years. Apart from these subjects the main topics of the study are today?s and tomorrow?s situation regarding technology, charging, fuel, market and economic incentives from an electric vehicle perspective.

The objective of this thesis was to develop a method for the planning of road upgrading at Holmen Skog, a Swedish forest company. A critical issue for creating such plans is to identify roads that are suitable to upgrade to a standard that can handle heavy traffic during spring thaw, since spring thaw is a bottle neck for transporting timber. The method was tested in a case study at a district. The work consisted of two parts. The first was to retrieve and prepare geographical data for the roads.

Following an increase in hostile foreign activity. The discussion regarding Sweden?s defense force´s ability to perform its task has come to a new heading. With the end of the cold war as a major revolution in matters of international security, a major overhaul has taken place to transform the static total defense plan of the nation to a less rigid operational system.Following an analysis of the budgets total amount from the governments of 2002 until 2015 it is clear that while the amount of resources has never directly been lowered, it has shrunk in relation to the countries total GDP. The possible futures for the defense of Sweden bring three possibilities forward in correlation three unique perspectives on military and political policy.Out of the three possibilities the focus on military strength as a political resource seems to be garnering the most support with the latest incursions made my foreign submersibles and the ever growing presence of 5th generation of warfare.

The purpose of the study is to investigate and elucidate how low-cost airlines can influence and develop tourism in a region. In order to bring about the purpose the author used two research questions. Have low-cost airlines contributed to regional development? How many additional visitors have low-cost airlines contributed to Stockholm? In order to answer these questions a survey was carried out at Arlanda airport and statistics were collected. The results of the study show that there has been a regional development.

Swedish agriculture stands in front of big changes the whole time. As a milking producer you have to adapt and develop the company to these changes and find the best solution. This potential is easy to find if you compare your company with other similar companies. Labour cost is the biggest cost in milking production after the cost for food. Today it is rather easy to measure how many hours per cow different system of cow houses needs, but we do not know so much about how many hours it takes to breed a calf. To learn more about the labour time with the calves during the first time after the calf was born, I made time studies on five different farms with calf hutches, automatic milk system, large calf boxes, and smaller calf boxes with teat buckets.
