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..

Internet är ett globalt nätverk som förser en användare med ofantliga mängder information. Internet ger även användaren den unika möjligheten att själv publicera sin information utan någon form av kontroll. Den möjligheten har gjort att mycket missvisande och falsk information finns tillgänglig på Internet. Det är helt upp till användaren att försöka avgöra om informationen är sann, giltig och korrekt, det vill säga trovärdig, frågan är bara om användaren gör det?Följande examensarbete har undersökt om en erfaren Internetanvändare utför någon form av källkritisk granskning, eller överhuvudtaget funderar över trovärdigheten hos information från webben.

This thesis describes possibilities for Metso Paper to lower their costs of spray pipes for their pulp wash press TRPE, with maintained good functionality and quality.Information that can be used by competitors has been censored in this version of the essay.To find solutions, alternative suppliers have been contacted and asked to quote. There has also been a new spray pipe designed. The manufacturing costs of the new design have been calculated.The thesis also contains a concept generation of an alternative product to the spray pipes in installations where a high pressure washer is used.To be able to ask other manufacturers of spray pipes to quote, a demand specification based on the currently used spray pipe was made. This was then sent to two alternative suppliers.An investigation of earlier used spray pipes, and the currently used, shows that the nozzles are a big part of the total costs of the spray pipes. To attempt to reduce the nozzles high cost an concept generation was made to find the best solution for a new design.There was a request that it should be possible to change the internal brushes in the spray pipe without cutting and welding.

 With the increases in fuel costs due to the depletion of the world oil reserves and the increase of greenhouse gasses as a consequence to using oil as a fuel many companies are looking to new and innovative ways to power their aircraft. One of these new ways to power an aircraft is using fuel cells powered using hydrogen and oxygen, thus producing nothing but water vapour and small amounts of nitrogen dioxide as well as trace amounts of other emissions. Both Boeing (1) and Politecnico di Torino (2) have shown that it is possible to build an all-electric aircraft powered by fuel cells. Both flights used small, two-seater aircraft and a constant between them was the loss of the co-pilot seat due to weight and lack of space. As this paper will deal with a commercial aircraft a primary concern is the cargo and passenger capacity and whatever impact switching propulsion system has on these.

A cochlear implant (CI) is a hearing device that makes it possible for individuals who are deaf or has a severe hearing impairment to receive auditory information and develop spoken language. The pragmatic ability may be affected. In short, pragmatics may be described as the study of language use in social contexts. Pragmatic ability can be seen as the result of the individual?s behavior as well as the underlying causes.The aim of the present study was to describe the pragmatic ability in children with CI.

The purpose of the present investigation was to identify how knowledge about goal-setting is developed and applied in practice of male players in the Swedish national floorball team, by using a qualitative methodology. Participants were 6 players playing for the Swedish national team. They were asked to respond to the interview questions in relation to their perception of setting goals for a successful outcome in sports, how their goal- setting process has developed and how they deal with goal setbacks and goal attainment. Results revealed that Swedish national players in floorball employed goal setting often for both individual and team goals in practice and competition. In addition, many interesting findings regarding the process of goal setting emerged in the result.

Questions about discipline have always been current within the Swedish school system, from the sixteenth century until today. The purpose of this study is to compare the discipline in two old-time elementary schools, located on Gotland, with each other.This study will compare an old-time elementary school from the countryside with an old-time elementary school from a town to show the differences in discipline between the coun-tryside and a town. This study will also focus on how questions about discipline changes from 1847 to 1937/1941. In order to do so I have studied the regulations from the two schools and compared them with each other. When I discuss discipline I will use Michel Foucault?s theory concerning the development of power and discipline in modern society.My study shows that it did not differ much in questions of discipline between the two ex-amined old-time elementary schools.

The health care formulation of the principle of autonomy can be expressed as follows; ?you shall not treat a patient without the informed consent of the patient, or his or her lawfulsurrogate, except in narrowly defined emergencies?. The principle of beneficence refers to a moral obligation to act for the benefit of others. In heath care, the good or benefit in question is the restoration of the health of the patient. In fulfilling this obligation of beneficence, the physician sometimes intentionally overrides the patient?s preferences or actions for the purpose of benefiting the patient.

Aqeri has since the past year a new profile with name and logotype, which has createda need for an updated visual product identity. The company is a leading developer,producer and distributer of IT products suitable for extreme environments in industry,defense and vehicles. This new profile with the different segments has together with aproduct identity from two companies resulted in that they have no clear designidentity on their products. From this background the aim of this research is todetermine how a development of a design identity is done to implement it to Aqeri.The design identity can be defined as a product?s identity visualized through its formor appearance which defines what the product is.

Today the Internet is used more and more as a transportation for information. Much of the information is confidential and should not be read by those not privileged. To protect the information from unauthorized access cryptography can be applied. The cryptography algorithms in use today all have their pros and cons. They are therefore suited for different applications.

The purpose of this thesis is to study how Malaysia Airlines communicated during the two largest crises of 2014. Key questions to be answered are: Did organizational hypocrisy occur? If yes, in what way? Which communication strategies were used? Did the company mediate an unequivocal message and how was the information framed? Did any aggravating factors, which worsened the organization?s reputation, appear? How did Malaysia Airlines manage possible rumours? Was the word contact used as a keyword? The method of choice is a quantitative content analysis and the material consists of 20 different analysis units. These analysis units were collected from social media and Malaysia Airlines website. The quantitative content analysis is based on the theory Situational Crisis Communication Theory, taken from PR, Strategy and Application, Managing Influence, by W.

The wood-living beetle Ceruchus chrysomelinus is a rare species connected to natural forests. In Sweden, it is red-listed as endangered (EN) and an action plan for its preservation has been done by the Swedish Environmental Protection Agency. In this work I have therefore investigated how a translocation of the species succeeded after 17 years. I aimed to study the species dispersal biology, its substrate preferences and the supply of suitable wood on this site. The study was performed during 2012 in Pansaruddens nature reserve close to Uppsala in Sweden, which is a spruce dominated forest.

I have worked with Bergum in different courses on the IntegratedConservation of Built Environments program and I thought it was a veryinteresting subject. This is the main reason why I chosen to write mybachelor paper about Bergum.In 1650s Bergum was situated on the border between Sweden and Norway,because of that it occurred some war conflicts.Today Bergum is a socioeconomic border and is situated in an areabetween the city?s concrete suburb and the countryside.The difference between the city?s concrete suburb and the countryside mayfeel like two different worlds, were the social contact is fractional.With this paper, I will indicate a countryside area on the boundary to the citythrough time and try to survey the building history. I will also try todemonstrate the socioeconomic differences between the areas.I will demonstrate Bergum history from prehistory to present time, were I willdiscuss the agriculture history, Vättlefjäll?s forest history and also thedeforestation and replanting.

Slovenia and Latvia are two examples of countries which have gone through a successful democratic transition. They were both under authoritarian rule and command economy up until their declarations of independence in the early 90s. Today they have a functional market economy and political pluralism. I have examined transition theories highlighted by Jonas Linde and Joakim Ekman and from these theories sought the explanations to what lies behind the successful transitions of these two countries. The transition in Slovenia was affected by liberalization from within the ruling communist party which then controlled much of the transition process. A relatively large civil society and the fact that Slovenia was not involved in the Balkan War also contributed to the short process.
