Materialdistribution i ett tillverkningsföretag : en fallstudie av PartAB

The purpose of this project is to study Partab's material distribution process, furthermore identify critical problem areas within the company. Further the aim is to provide suggestions to new work procedures regarding material distribution and related processes. Appropriate literature has been used as a support in this process. The main goal of a commercial company is to generate cash flow, and maximize the return on investment. Streamlining material supply and the use of material is a part of this process. Virum and Persson define logistics as: "Logistics is the approach and principles founding the process of planning, development, coordination, organisation, management, and control of material distribution from supplier to user".

DATORSTÖD FÖR ARBETE - KONSEKVENSER FÖR VAL AV AFFÄRSSYSTEM En studie av en service- och supportavdelning

This report is focusing on problems with introducing standard enterprise resource planning systems (ERP) in businesses. A study has been carried out on a service and support department at a Swedish heat metering company, SVM North Node. The study aims to help the company become a better customer in choice and customization of a new ERP system. We make a description of the department studied and the work carried out there, on the basis of learning, knowledge and cooperation. As a final point we present some ideas on how computer systems could support their work, hoping that this will result in them making adequate demands on a new ERP system.

Hållbarhetscertifieringssystem och kommunalt hållbarhetsarbete :  

The municipalities of Sweden have a great responsibility when it comes to adapt the physical planning to a more sustainable development. The development of the society depends upon the growth of new communities and other public services, but to build new communities in a long-term sustainable manner you need good methods and guidance. This study presents four sustainability certification scheme intended to improve and adapt the planning, implementation and performance of new communities and infrastructure project to more sustainable methods based on economic, ecological and social sustainability. These systems are the latest versions of environmental classifications and similar rating schemes, but with a broader focus since they also include the social aspect of sustainability.This study aims to investigate what role sustainability certification schemes can play in local planning for sustainable development. The study compares the certification systems criteria to the tools and goals that the Swedish municipalities have been provided with, to lead efforts towards a more sustainable society.

Regulatorer med styrsignalsbegränsning

This thesis studies the negative impact that control signal saturation may have on a controlled system. Different methods that are used to compensate for this problem are also studied and evaluated. Both sensitivity to disturbances and the effect the method has on the systems'ability to follow a reference signal will be examined. Stability will be discussed, but no conclusions whether the systems are stabilized or not can be drawn. Control signal saturation will lead to a slower behavior in general.

Kollektivtrafikanalys av Frihamnen Göteborg. En studie av olika utbyggnadsscenarier och dess transportbehov vid en färdig utbyggnad av Frihamnen år 2040

The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

Legionella i tappvattensystem. Förekomst och förebyggnade-en redogörelse.

Legionella can be prevented, the question is how. This report is a degree in construction engineering education at Chalmers University in Gothenburg. A comprehensive written publication for Legionella-safe plumbing installations is not available and therefore requested. The purpose of this report is to present preventative measures against Legionella bacteria growth in tap water and in other systems where Legionella bacteria are a potential problem. Technical solutions are presented including how different systems function and what their advantages and disadvantages are.

Osäkerheter vid brandteknisk dimensionering av ventilationssystem

This masters thesis deals with smoke spread via ventilation systems. One aim of the thesis is to investigate and explain the differences in efforts to prevent smoke spread via ventilation systems in different countries. A second aim of this thesis is to investigate how frequently occurring smoke spread via ventilation systems in Swedish buildings are. A third aim is to investigate how uncertainties in input variables to smoke spread calculations will affect the result of calculation. To be able to do this the most important input variables are identified and analysed.

Integration mellan system : En undersökning av olika framgångsfaktorer

This paper exposes the problems and challenges organizations face when integrating aged systems, web based systems and web services. The paper focuses on how people with different titles in an organization experience systems integration and the factors that contribute to project failure or success. The research methodology used in this is Grounded Theory and the resulting theory of this paper has taken form through the coding of transcribed interviews, which have gone through a constant comparing to other theories in the area of interest, mostly articles about success factors in system integration. The resulting outcome is a success model aimed to describe the underlying indicators to achieve project success.The success model consists of three factors that contribute to success in integration projects. The factors are: globalization, governance and balance.

Nio individer från Västra farleden : en osteologisk analys av nio individer från medeltida Västergarn, Gotland

Osteological examinations were executed on nine mediaeval individuals from Västergarn, Gotland, with the main aim to increase the knowledge about the people who lived there during the Middle Ages. A further aim was to compare the results from this study with other populations from the same time period, which in this case was the "Bonegathering" from Västergarn as well as previous osteological results from Sigtuna and Västerhus. Archaeological excavations have been occurring in Västergarn since 1971 and are still occurring in an educational purpose, for students of Gotland University. The age distribution of the individuals showed ages from 2 years old up to 44 years, with five adults and four children. The gender distribution show approximately five women and one man.

Chefers och medarbetares perspektiv på motivation : En studie inom internationellt verksamma företag med grossistverksamhet

This system, called CollMX, will be evaluated and different ideas for future development will be presented.  The evaluation and ideas are generated by an empiric evaluation and research in different areas related to CSCW. The research does not only focus on the area of CSCW, but also extends towards the Web 2.0 and ideas about awareness..

Klassning av fjällbjörkskog enligt FAO:s definition av skogsmark med hjälp av flygburen laserskanning

Sweden?s forestry legislation was updated in 2010 and a new definition of forest land was introduced. This definition was adapted to the one used by the Food and Agriculture Organization of the United Nations (FAO) for international statistics on the state of the world's forests. It is in short based on the lands ability to grow forest that reaches 5 meters, 10 % canopy closure and has a continuous distribution, according to FAO at least 0.5 hectares. A country-wide laser scanning is now carried out for the production of a new national elevation model; the laser data also provides information on forest height and density.

Vårdvalet - Val för alla? : Granskning av fördelningen av vårdcentraler före och efter vårdvalsreformen

This master thesis is an analysis of how the amount of health centers per inhabitant has changed since the Swedish government implemented a new health care reform in 2010. The reform implies a free choice of health centers in the Swedish regions and opens up the market for private firms. The purpose of the thesis is to study the effects of the different financing systems toward the health centers in the regions. The models are based on theories of the need of health care. Two of the independent variables which are studied are income and age.

25 år senare : en nyinventering av keramiken på Ajvide

This thesis examines a sample of Pitted Ware pottery from the Gotlandic site of Ajvide in regard to the spatial and temporal relationship of the shards. Ajvide Stone Age site have been extensively excavated over the past 25 years and the most recent analysis of pottery was carried out by Inger Österholm in 1987 and new analyses of the material are therefore greatly needed. Pottery from three sample areas was analysed in regard to their distribution, decoration, fragmentation, part of pot and quality of the goods. To analyse the material in a contextual way a multivariate statistical analysis called correspondence analysis was used. Two areas denominated ?dark areas?, which Österholm defined previously, as possible ritual sites, and one reference area with mixed material were chosen for the analysis.
