Konvertering från direktverkande el i kommersiella lokaler : Ekonomisk och hållbar utveckling

Buildings worldwide account for 40 % of the total energy use. Climate change is of increasing importance, but few are willing to reduce their standard of living or get a higher cost for the change. Energy efficiency of existing buildings gives the greatest benefit economically and environmentally. The real estate company Klövern AB manages 46 properties in Karlstad. Heating is the major cost of the total operating costs of real estate. Rising energy prices increase the need for Klövern AB to improve energy efficiency and to investigate alternative sources of heat.

Familjen i skuggan av alkoholismen: om medberoendeproblematik ur klass-, kultur- och könsperspektiv

The aim of our thesis was to describe how the connection between co-dependent relatives and the alcohol-dependent influences the family into changes in their teamwork.Our purpose was also to answer the following questions: How is it living with an alcoholic? Are there any differences in how men and women feel and behave in their relationship with an alcoholic? Are factors like cultural belonging, genre or social class important for how the co-dependent relatives feels and behaves and handle their co-dependency?To answer these questions we made twelve thematic qualitative interviews with six adult children to alcoholics and six people married to alcoholics. We compared the results of these interviews with earlier research. We also applied System Theory and Goffman's Role Theory, as well as Bourdieu´s Capital and Habitus concept.We believe that co-dependency is a family divergence that is very similar to family disease, but that a change in attitude can trigger recovery. According to the interviews many spouses stand by their alcoholic husbands and do actions that perpetuate the alcoholic dependence and thereby hold back any recovery.

Miljövärdeflödesanalys av Risifruttiproduktionen : En utvärdering av värdeflödesanalys och miljövärdeflödesanalys

This report is the result of a thesis work carried out on the Risifrutti production at the company Procordia Food AB. The thesis is at a master level and is the final work for the author to receive a Master of Science in Innovative production at Mälardalen University. The thesis comprises 30 credits and has lasted for 18 weeks. The thesis is mainly a research on whether it is possible to perform an Environmental Value Stream Map (E-VSM) in a food processing industry and an evaluation if the tools E-VSM and Green Performance Map (GPM) are useful in this type of industry. An extra part to this research is to use the results from the E-VSM and give Procordia Food AB information on improvement potentials in the Risifrutti production. The author has found it difficult to collect some of the quantitative data to the E-VSM, mainly regarding energy, but by using the Value Stream Mapping (VSM) tool and other Lean tools the author was able to identify and quantify several wastes in the Risifrutti production. Recommendations for improvements based on these wastes have been given to the company. In the research part of this report the utility of the Value Stream Map, Environmental Value Stream Map and Green Performance Map in a food processing industry have been analyzed. The author has found that the Value Stream Map has been a useful tool since waste and unevenness in the tact of the production has been identified. The Environmental Value Stream Map and the Green Performance Map are also great tools when a company wants to analyze their environmental impact and then invest in environmental improvements. However, no profound energy analyzes has been done in the Risifrutti production because of the lack of energy meters for steam, electricity and compressed air in the production lines..

"Folk är inte lika för att dom kommer från Sudan" : en översikt av förekomsten av familjer med annan kulturell bakgrund vid Familjenheten i Lund

The purpose of this study was to, using statistical analysis, investigate to what extent families of a different cultural background have participated in family therapy and other family treatment programs at Familjeenheten in Lund. With questions regarding the goals of treatment, and the importance of cultural competence in the treatment process we have let two unit managers comment on the statistics. The population of the study is too small to allow general conclusions to be drawn, however, we have been able to ascertain that families of a different background are over-represented relative to their percentage of Lund´s population. Familjeenheten has no statistical record of ethnicity and the interviewed persons express no certain importance in the families´ cultural origins. They express no need to develop special treatment methods that take the clients´ cultural background in regard as they feel that so many of family issues are universal.

Projektledningsmetoders syn på slöseri inom mjukvaruutveckling : Vad är slöseri inom mjukvaruutveckling och hur kan det minimeras?

SammanfattningBegreppet slöseri, av engelskans waste, är en term som i dagsläget saknar en klar och entydig definition inom mjukvaruutveckling. Denna rapport har skrivits vid Kungliga Teniska Högskolan i Stockholm och syftar att klargöra termen slöseri och vad den innebär men hjälp av olika projektledningsverktyg från IT-branchen. Det har framkommit att förtag sällan jobbar med en och endast en projektledningsmetod inom mjukvaruutveckling utan det blandas verktyg från olika metoder. Det är ofta brist på kunskap om valda verktyg och hur de ska användas samt vilka olika verktyg som kompletterar varandra eller ej är kompatibla med varandra. En ökad medvetenhet kring valda modeller och verktyg skulle leda till ökad effektivitet och minskat slöseri.

Nyttjande av ofrörbrukat byggmaterial : En rapport åt Peab Jönköping

This final year project is made for Peab Jönköping and its target group is the construction industry. The main focus is the use of unutilized building material in the most economical and environmental-friendly way. Unutilized building material is here defined as material purchased for a construction project that for different reasons not has been used. The most important thing to find out was how much building material considered as being waste is actually useable material, and how much less it costs to use that building material instead of throwing it away.When this information was gathered a proposal on how to efficiently use the unutilized building material instead of wasting it was designed. Costs and incomes were investigated and the proposal suggested a storage area where Peab can store their unused building material.

Information Audit en informationsgranskning vid Borås Stads äldre- och handikappomsorg inom kommundel Centrum.

An information audit identifies, among other things, organizations information resources, the information flow and the needs of the information users. The purpose of this masters thesis was to describe the management of information within a local unit of Borås municipality by putting an information audit-method in practice. The focus was on three issues: What information needs could be seen in the organization? How does the information flow through the organization? How does Sugan Henczels seven-stage model serve as a tool to map the management of information within the local unit? The study only described the situation at a certain time at the chosen organization. The seven-stage information audit model was revised and adjusted to the studied organization by only carrying out four of the seven steps: Planning, Data collection, Data analysis and Data evaluation.

"Då rökte jag på. Sen började jag lite med tjack och sånt också." :en studie om hur ungdomars missbruk påverkar familjen

The purpose of our report was to analyze the effects of youth drug abuse on the families concerned. Youth drug abuse made us wonder about the effects on the family as a whole, of those involved with drug abuse. To answer this question, we decided to employ an empiric study in the form of interviews with four teenagers, five parents and four drug counselors. Because our intent was to understand rather than try to measure the problems involved, we decided on a qualitative method. Our method built upon semi-structured interviews using open questions, where the interviewees were free to express their own thoughts and opinions.

The work has also included studying the possibilities to change the material flow in a positive way between the storage and the production when one is using existing buildings.During our work we have been used a simulation program called AutoMod, performing company visits, interviews and reviewed internal and external information to create a picture of what the best conclusion can be. During the work we have contacted five suppliers to receive system solutions and quotatioris. The suppliers, which have been contacted, are Swisslog, Moving, Rocia, Christensen & Hansen and ABB.

Tillståndsprövning - för lantbruk med djurhållning : en intervju undersökning med länsstyrelserna i Kalmar- och Hallands län.

The task of making a correct application for B- activities is the foundry time consuming task. Information and facts concerning your entire business activity shall be attached into a description of environmental consequences, which will be the basis for the decision making whether the activities shall be granted a permission to practise environmentally hazardous actions or not. When the Environmental Act were established 1999, the permission process became more extensor. With this study I want to give an insight about how these applications are made. The methods I have used to collect information are a study literature where the Environmental Act has been the focus, and qualitative interviews with two County Administrative Board. I used the Environmental Act to understand why permission is needed and the interviews to give me insight in how the work is done. My conclusion is that it is very unusual that an application is granted without complements.

Situationer och varumärkeslojalitet : Hur återkommande köp- och konsumtionssituationer är kopplade till konsumenters varumärkeslojalitet

The thesis focuses on the measurement of situational factors affecting brand loyalty in purchases and consumption. A survey is conducted using previously developed scales and 199 respondents. Results show that for the particular product category (ready-to-drink recovery drinks), purchase frequency and the product experience have stronger effects on loyalty than do situational factors such as type of activity and perceived stress. Implications for managers are discussed and suggestions for further research is presented..

Effektiv partiformning : analys och tillämpning på Uppåkra Mekaniska AB

This paper is the result of a case study conducted at Uppåkra Mekaniska AB during the spring of 2006. The task that was presented by Uppåkra was to develop a basis for a decision for the planning activities at the company, so that in the future they can create lot-sizes which are based upon a total cost perspective. Total cost in regards to lot-sizing is defined as the sum of the administrative reordering costs and warehousing cost per stock keeping unit.To collect data a series of interviews and observations were conducted. This data was then used during the lot-sizing simulation and analysis. The 15 units that the simulation was conducted on were grouped into three item classes depending how many different machine setups they required during the production process.

KORTSIKTIG PRODUKTIONSPLANERING I MINDRE FJÄRRVÄRMESYSTEM : En studie vid Strängnäs Energi AB

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.
