Lantbruksföretagets utveckling av ny verksamhet : en studie av fem lantbruksföretag
The structural rationalization of rural firms in Sweden has led to many new creative ways of developing companies. The agriculture sector is characterized by the need of capital in form of buildings, labor and inventory. The rationalization process has led to free capacity in rural firms when new technology make buildings and inventory not longer necessary for the production process. To get a better cost coverage this free capacity can be used to start-up new business areas that help the rural firm to growth.The study aims to identify factors that motives entrepreneurs in rural firms to develop new business areas. The purpose is also to analyze driving forces that lies behind development of rural firms and the forces that support or not support development in rural firms.The study is built upon five cases that all can be categorized as firms with different size and orientation.
Intranät : en kunskapskälla i arbetet?
The ambition with this study is to look into and create an understanding for how an intranet can work as a support system in work processes in capacity as a source of knowledge. We want to enhance the understanding for which kind of knowledge that can be coded in and transmitted by an intranet, and which that is lost in this process. We also want to clarify what it takes to get this knowledge, in collaboration with the intranet, to support the work in an organization. It is a qualitative case study at a Swedish bank. It consisted of semi standardized, half structured interviews with five people in one of the bank?s local offices.
Transporthantering En utvärdering och analys av inboundtransporter vid Sulzer Pump Solutions Vadstena AB
Logistik har på senare tid blivit en allt viktigare del inom dagens samhälle i och med ökad globalisering. En verksamhet som effektivt arbetar med att förbättra sin logistik kan ofta erhålla stora konkurrensfördelar och om möjligt utöka sina marknadsandelar. Logistik medför dock ett antal kostnadspunkter, varav en utav de största är transporter. Av denna anledning är det av stor vikt att företag erkänner hantering av transporter som en central del utav den dagliga verksamheten.Syftet med detta examensarbete är att på Sulzer Pump Solutions Vadstena AB utvärdera samt studera verksamhetens transporthantering med fokus på inboundtransporter.I samband med ett ägarbyte har verksamheten genomgått stora organisationsförändringar där transporthantering har kommit att bli ett icke prioriterat område. Företagets transportkostnader är idag omfattande och det finns en tydlig önskan om att ta kontroll över transporthanteringen.
Undersökning av integreringsmöjligheten av två monteringsceller på IMO Pump
In order to measure the quality of the logs, one can with help of Fast Fourier Transform technique get the signals resonance peaks. With help of these peaks you can see whether the quality of a tree is good or bad. This report contains the work of a where a program has been developed to be able to process a vibration created by an automatic hammer hitting on a log of wood. From the processed signal the program should be able to show both the raw wavesignal and the processed measured data from the resonance peaks. Beyond the raw wavesignal and resonance peaks the program should also be able to control the automatic hammer.
Forestry supply chains : preparing for the unpredictable
Forestry supply chains are a significant part of the Swedish economy. These supply chains are highly susceptible to storms damage. In late 2013 Sweden was hit by multiple storms. This leads to the possibility to research how supply chains react to the shocks that storms cause. The aim of this thesis is to research the costs that storms increase, the actions that are taken within the forestry supply chain, as well as possible benefactors from storms.
This thesis bases on previous work on supply chain mapping and cost theories.
Optimering av påstorkning : Från behov till färdig konstruktion

Metodik för testning av styrsystem
I detta examensarbete har en generell metodik skapats för testning av styrsystem för pumpar. Testmetodiken beskrivs med modeller som på ett strukturerat sätt går igenom testningens förberedelse och utförande. Metodiken tillämpas sedan genom en stegvis mall för hur testningen går till praktiskt.En metod för att optimera antalet tester presenteras. Denna metod minskar antalet tester genom att använda de mest prioriterade signalerna som skickas mellan styrsystem och pump. Denna prioritering sker genom en viktning av hur viktig signalen är för systemet.
Effektivisering av korta cirkulationen Pappaersmaskin 2 Stora Enso Hylte Bruk
Stora Enso Hylte Bruk är ett tidningspappersbruk beläget i Hyltebruk.De fyra pappersmaskinerna startades 1972(PM1), 1974(PM2), 1976(PM3) och1989(PM4).Produktionen 2005 från dessa pappersmaskiner var 800 000 ton papper.För att tillverka papper åtgår stora mängder energi i form av värme och el, HylteBruk gjorde 2005 av med 1 % av Sveriges totala elenergibehov.Den 1/7 2004 höjdes processrelaterad elskatt från 0 till 0,5 öre/kWh vilket leddefram till den lag som trädde i kraft den 1/1 2005, ?lag om program förenergieffektivisering? (PFE)1.Ändamålet är att främja en effektiv energianvändning och ger energiintensivindustri möjlighet att delta i ett 5-årigt program för energieffektivisering. Deföretag som är kvalificerade att ingå i programmet och klarar av de krav som ställsbefrias från elskatten.Som en del av det här programmet ingår att utarbeta en lista medelenergieffektiviseringar som ska överlämnas till Statens Energimyndighet.Detta examensarbete kan efter beslut av ansvariga på Hylte Bruk ingå som en delav denna lista.Syftet med examensarbetet var att undersöka effektiviteten hos tolv pumpar påPM2 genom mätning av effekt, flöde och tryck. En del av dessa har varit i drift iupp till 32 år, under denna tid har slitage skett, vissa pumpar har gått mot delvisstängda ventiler samt förutsättningarna i form av produktion har ändrats sedan dedimensionerades.För alla de berörda pumparna kan en effektivisering göras, den kan bestå av: lägretryckhöjd, mindre flöde, pump med bättre verkningsgrad, eller en kombination avovanstående exempel.De förslag som har en återbetalningstid kortare än tre år ger tillsammans enenergibesparing på 1 375 000 kWh/år, vilket motsvarar mer än ¼ av vadpumparna förbrukar idag.Om istället alla de förslagen som är framarbetade och genomförbara skullerealiseras kan energibesparingen ökas ytterligare till 2 302 000 kWh/år, dettaskulle dock innebära en större investeringskostnad vilket resulterar i en längreåterbetalningstid..
Utvärdering av kalkstens egenskaper med laboratorie- och fältmetoder.
A pavement construction designed to cope with the different type of traffic loads; it is exposed to and at the same time it can resist the effect of the climate. A road structure consists of sub- and superstructure which is divided by a boundary known as terrace. During the construction of unbound layers (base course and sub-base course) in the superstructure, it is always ensured that the material meet the requirements for bearing capacity and the degree of compaction. These parameters are controlled by various laboratory tests and control methods. To obtain increased knowledge of the material and improve the quality of the compaction in the field, it is necessary to perform laboratory tests in order to determine material properties.A base course material 0/ 32 mm limestone from Gotland (Hejdeby) was investigated in this study.
Enkät för skattning av 8-åriga barns fysiska aktivitet : En valideringsstudie. Frågor ur SIH-enkäten jämförda med referensmetoden accelerometri
AimTo validate the STOPP-8-questionnaire (S8Q), containing items from the SIH-questionnaire, against the criterion method accelerometry to estimate its capacity to assess 8 year old Swedish children?s physical activity (PA). Can it assess children?s physical activity? Can it differentiate the active children from the sedentary? If the answer is yes, how well can it do so? MethodData was collected during fall and winter the school year of 2008 - 2009 via the project STOPP-8. Out of 676 children at 12 schools in Stockholm area, 155 (boys n=72, girls n=83) provided complete questionnaire data and wore an accelerometer (Actiwatch 4) during 7 consecutive days which provided data for mean and median activity, time spent sedentary, in moderate to vigorous PA and vigorous PA.
Att göra förändring: en studie av ledarskap och organisation vid förändringsarbete
The purpose of this essay is to analyse how the leadership and the structure of the organization affect the process of changes within a specific department in Lunds kommun socialdepartment, from the director of social work to the co-workers at Utredningsenheten för ungdom och familj. We aim to answer the following questions;How does the structure of organisation affect the process of change?What do the co-workers and the leaders believe is the best way to engage the co-workers in the change?How does the leaders view their own leadership in the process of change?How does the co-workers view the leadership in the process of change?How does the leadership affect the process of change?To develop an organisation and to make it a functional, change is a necessity. The leaders are they who create the change but the co-workers are they who make it happen. In the process of change, leadership and the leaders capacity to create motivation for the co-workers, is therefore a matter that is decisive to its success.This is a study based on a qualitative method, where the interview is the main source of empirical material.

Sveriges potential för elproduktion från takmonterade solceller : Teoretisk, teknisk och ekonomisk analys
The Swedish potential of electricity production from roof mounted solar panels has been determined in three steps: accessing the existing roof top areas, simulating the amount of electricity solar panels can produce on these areas and finally analyzing how large the necessary economical change is to make the solar cells profitable.The total existing amount of roof top areas are 319 square kilometers and the area distribution follows the distribution of people. This leads to an installed power of 47,9 GW which are expected to produce 49,0 TWh electricity per year. If the quality of the electricity is prioritized the highest the power is reduced to 3,7 GW, generating 3,8 TWh yearly, but if the hosting capacity is calculated from Sweden?s total electricity need, the capacity is 42 TWh per year.Today, solar panels are not profitable in Sweden for houses, even though there is a subsidy of 35 % of the investment costs, discounted in 25 years. The profitability is calculated with a cost of capital of 5 %, a price on electricity of 1 SEK/kWh and an investment cost of 20 SEK/Wp.
