Professionell färdighetsutveckling på ett civilingenjörsprogram : en utvärdering av kompetenser hos alumner
The Master of Science in Energy Systems Engineering program at Uppsala University started in 2000 and 221 students has graduated since. This master thesis aims to answer what competencies alumni considers most important for successful professional practice. It also seeks to find out how these competencies are reflected in the program to identify potential gaps between importance and how the competencies are being prepared. With inspiration from similar research a method has been developed consisting of two steps: (1) A survey and (2) interviews with alumni. The alumni survey rates the professional importance of 13 competencies and how well the corresponding competency is prepared in the program.
Increased growth in Norway spruce (Picea abies (L.) Karst.) through small annual additions of nitrogen (N) fertilizer
This project investigated how elevation and vegetation type influences variation in plant litter phenolic content and protein precipitation capacity among and within common plant species for two different vegetation types, heath and meadow, in a subarctic ecosystem in the Abisko region of northern Sweden. As nutrient availability generally decreases with increasing elevation as a result of decreasing temperature, I hypothesised that phenolic content would increase with elevation and be higher on the heath than the meadow. To test this, the total phenolic content and protein precipitation capacity was estimated in leaf litter from 13 species in both heath and meadow vegetation across an elevational gradient ranging from 500 to 1000 meters above sea level (m.a.s.l.) in the study region. The results showed that elevation and vegetation type both had a strong impact on both variables. Total phenolic concentrations decreased with elevation for the meadow, and were greater for the heath than the meadow.
Individers betydelse för kunskapsöverföring i en organisation : En studie om hinder och möjligheter till lärande på Metso Paper Karlstad AB
Companies learn through their employees. In this paper I make research into how knowledge transfer and learning occur at Metso Paper Karlstad AB, which is a partly project based organization.The result is that there are many factors that affect the knowledge transfer in a company. Knowledge transfer occurs mainly between individuals within the company, but also between departments and other actors outside the company. In the gaps between these actors, there is a risk that knowledge is not transferred, which is an obstacle to learning. A great deal of the knowledge transfer and the learning is carried out through individual?s own drive and motivation.
Geotermisk fjärrvärme i Gunsta
Gunsta is situated about 10 km east of Uppsala. Today there are plans to establish 1000 new households in Gunsta before year 2030. The required energy for heating houses and water would be distributed via a district heating system, which also includes 200 existing residences. The annual required energy, according to this study, would be 16.2 GWh with a maximal peak effect of 6.9 MW.
To meet this need, the study suggests a system with heat pumps to upgrade the 31?C water from a 1.8 kilometre deep borehole.

Igensättning av övre spalten i centrifugalpump
This report focuses on the upper slit. The upper slit is located between the impeller andthe drive unit. The slit design depends on pump type and application. However it isuncertain why the design varies, The purpose of this report is to clarify why the designvaries and to recommend an improved slit design.A research has been done; information was gathered from interviews, but also fromsearching of databases and studies of drawings, reports and documents. The originalpurpose of the slit was to prevent twining around the driveshaft, and prevent dirt fromentering the cooling system.
Trygghetens dilemma : trygghetsskapande arbete i det offentliga rummet
This graduate thesis is engaged with perceived safety and "safe making"
design in public places. Despite the fact that we have never been as safe,
questions of safety get more attention than ever in today?s society. Public
demands for safer and more secure environments and low levels of experienced
feelings of safety indicate problems in society that can shrink
people's usage of public places as well as their quality of life.
Through methodical exaggeration of danger and legislation of laws, the
state creates a situation that in different respect work to overprotect the
citizens, who are not unlikely to experience feelings of being unsafe at
the same time that the actual safety is to big. An expansion of protection
against fear can unlike what was first intended decrease the experience of
safety.
Anledningar till staters anskaffande och behållande av kärnvapen och faktorer som påverkar staters kärnvapenpolitik
The purpose of this thesis is to explain why states obtain nuclear weapons and the role variousactors and interests play in the making of states´ nuclear policies. The main questions are asfollows: (1) What big theories exist concerning states obtaining nuclear weapon and nucleararmament in International Relations and what relevance do they have of the post cold-war period?,(2) What is the meaning of the perspective of the Military-Industrial Complex (MIC)?, and (3)Arethere empirical studies which supports the existence of a MIC in the United States?The focus lies on actors and driving forces that are internal to states and it is also important toinvestigate if the theories have relevance for the post 9/11-era. The study uses the method ofqualitative literature-study with some quantitative segments. It is claimed that states might beinterested in justifying their behaviour in a morally appealing way and that real reasons may behidden.
Varför bör kvinnorepresentationen öka? En textstudie av den interna debatten inom tre politiska kvinnoförbund under sjuttiotalet
When it comes to political representation, all over the world women almost always make up a minority of representatives in the legislative bodies. The Scandinavian countries in general and Sweden in particular have though been exceptions to this rule with, when compared to other countries, a rather high percentage of women in elected positions. This development took off in the seventies: during that decade the unit percentage of women in the Swedish Riksdag rose by double!The aim for this thesis is to analyse what underlying ideas influenced this advance. The focus is on three different female party federations, who are believed to have had a great impact on this increase of women politicians through their influence in their own mother parties. The federations analysed are the ones connected to the Social Democratic Party, the Centre Party and the Liberal party.
Kvalitetssäkring av gjutgods till verktyg och utrustningar för karosstillverkning inom bilindustrin
Detta examensarbete är ett försök att skapa en enkel handbok, där man lätt kan slå upp fakta om olika typer av gjutlegeringar. Samtidigt är det en undersökning om hur man kan förbättra kvalitetssäkringen av gjutgods. För att uppnå det förstnämnda har grundliga litteraturstudier utförts och resultatet har blivit ett antal avsnitt som tar upp det viktigaste om gjutning och gjutgods. I dessa avsnitt kan man läsa om olika gjuttekniker, legeringars gjutegenskaper, olika typer av värmebehandlingar, gjutdefekter, vanliga metoder för kontroll etc. Undersökningen av kvalitetssäkringen, och om dess förbättring, möjliggjordes genom kontakt mellan olika företag och genom att prova tekniker, såsom finita element beräkning (FEM) och gjutsimulering, och dra slutsatser från dessa resultat.
Finita elementmetoden och handberäkningar : En jämförande studie av beräkningar på väggskivor
Syftet med detta examensarbete är att undersöka och jämföra två olika beräkningsmetoder när det kommer till beräkningar av väggskivor. Den ena beräkningsmetoden baserar sig på traditionella handberäkningar där anvisningarna i BBK 04 (Boverket 2004) och Betonghandbok Konstruktion (Lorentsen, Mogens, Cederwall, Krister & Östlund, Lars (red.) (1990)) följs. Den andra metoden baserar sig på finita elementmetoden, och utförs med hjälp av programmet Strusoft FEM-Design Wall. Med Finita elementmetoden delas konstruktionen upp i flera små delar, så kallade finita element, som sedan beräknas var för sig, och sedan sätts alla delarna ihop till ett resultat för hela konstruktionen. Två olika väggskivor beräknades, en solid väggskiva samt en väggskiva med ett dörrhål i. Vid jämförelsen på den solida väggskivan visade sig resultaten stämma väl överens med varandra.
Driftoptimering av torkmaskin : Driftoptimering av torkmaskin 3 vid Billerudkorsnäs Karlsborg AB
The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.
Utrustning för automatmontering av ackumulator
This report deals with an exam report written by Olle Hjalmarsson and Thomas Likar, students at Högskolan i Halmstad. The project was carried out for Haldex Traction AB in Landskrona whose business consist of manufacturing automatic all wheel drive systems (AWD-system). These systems consist of a plate clutch which activates all four wheels of a 4-wheel driven vehicle. An important component in these clutches is the accumulator which basically consists of a piston under the load of a spring which creates an oil pressure with the help of an electric motor used for actuating the clutch.At Haldex difficulties has been experienced regarding the assembly of the accumulator parts due to the small tolerances between the piston and the hole of the accumulator in the cast aluminium housing. Attempts have been made to assemble the parts in existing robot cells.
En studie om ensamkommande barns situation
In this study the semi structured interview method was used to explore what kind of knowledge one In State Authority: The Migration Board, and three Non Governmental Organisations: Red Cross, Save the Children and ISS- International Social Service have about the situation for separated children. Another purpose in this study was to explore if people who are close to the children are working for the best of the children and if their cases were treated with legal security. The result shows that the children?s cases are not treated with legal security and some of the children suffer psychologically from separations from the families and other children need new families because they were maltreated. The result also shows that there are signs that separated children are discriminated compared to children with a Swedish background..
