Framtagning av ett nytt recept för clear-coat batter av pommes frites : En teknisk och sensorisk utvärdering

The requirements of good quality and appetizing fast food increases continuously as a consequence of a community where food is always available. The crispiness of French fries is an issue that must be considered in this context, since it tends to decrease and give the fries a soft surface not appreciated by the consumer. To prolong the crispiness, the fries can be coated by a batter, a mix of starches. The batters used often consists of modified starches, e.g. cross-linked, acetylated and dextrinizated to increase and prolong crispiness, flour to stabilize the batter and sodium bicarbonate to make the batter ?rise?.The cross-linked starch keeps the granules in a swelled state and prevents them from breaking when exposed to heat or processing: therefore, it delays the gelatinization and decreases the stickiness of the batter.

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.

Projektdokumentation : Kritiska framgångsfaktorer

Projects of all kinds generate documentation that needs to be organized and stored for future use. Well adapted tools, together with a unified modus operandi need to be available for both the project members and those having a more organizing role if an organization is to be effective.A study of the tools available to project members at Svenska Kraftnät have been performed along with an analysis of the guidelines for the tools' usage. The study has focused on the needs of the project members, not the organization as a whole, thus providing a bottom-up approach to the problem instead of the more organizational top-down approach. Interviews of around 20 project members, whose roles include project leaders, technical experts and documentation supervisors, have been conducted to get an idea of the practical problems that exists.All systems, except for a local network storage device, were found to at least meet Svenska Kraftnät's current demands. The usage guidelines, however, covers only the general process that a project should follow and lacks detailed information on a per system level in several areas.

Forensic Carving from Unallocated Space

Computer Forensics investigations have become more and more common while investigating IT-related issues. From experience, hard disks, USB thumb, memory sticks contains information that might be useful. Computer Forensics is regulary conducted by Police, Customs, Tax investigators but also within private companies and organisations. However, there are areas within the storage device that are not part of the organisied structure that a file system gives. The reason for that might be that the information has been erased by intention, a virus destroyed the file system and so on.

Bokslut? Den skönlitterära e-boken ur ett läsarperspektiv

The aim of this thesis is to accomplish a user study on how e-book users experience the electronic book, the e-book, as an instrument for reading fiction. The study is based upon qualitative interviews with twelve e-book users and a small survey carried out at the Stockholm City Library. The purpose is to identify the users' incentive for choosing the e-book as a medium for reading fiction, elucidate if and how the interface of the e-book affects the reading experience, and distinguish if there are any factors common to the users in their choice of reading e-books. How the users look upon the future of the e-book is also discussed. Among the people asked in the survey we note little if any demand for the e-book as an instrument for reading fiction.

Bland kranier, modeller och elektronmikroskop : Ett ordnings- och förteckningsarbete på Museum Gustavianum, föremålsmagasin Husbyborg, av handlingar rörande utgrävningen i Asine

This paper is an account of the inventory I've made of documents in the archive at Museum Gustavianum, Collections storage Husbyborg, relating to the excavations in Asine, Greece, in the 1920s. The aim of this inventory has been to establish which of the documents in the Husbyborg archives that belong to the department of Classical Studies at Uppsala University. Documents belonging to other archives have been found alongside the one mentioned above and those are the Original documentation (loan from Carolina) and the personal archive of Professor Axel W. Persson. The documents have been arranged according to the General Archive Scheme (Allmänna arkivschemat) seeing that the department of Classical Studies already had a series named Documents relating to the departments archeological collections, and the inventory I've made will be incorporated with that.

GIS-program för ruttplanering. En studie av nyttjandet av GIS-program för ruttplanering inom tekniska förvaltningar bland kommunder i västra Sverige

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

Utveckling av styrning till solföljande MaReCo-hybrid i Hammarby Sjöstad

Turning solar collectors, heliostats, is certainly not a new idea but has been explored for at least two decades. Projects on this subject have resulted in more or less realistic constructions, in a commercial point of view. Far too often the technical goals have had higher priority than the economical, which has resulted in a few constructions having the ability to compete with conventional, fix solar collectors. The economical issues have been given high priority in this project, without decreasing the demands on reliability. The system has been given the following mechanical and electronical properties: One-axis movement, fix heat carrying fluid system, microcomputer controlled movement and automatic protection from overheating.

Inköpsoptimering och kostnadsreducering

This thesis has been carried out at Diac Metal AB at Torsvik outside of Jönköping. The company produces parts for, amongst others, office furniture and store equipment. The essay will be concentrated on one detail which is included in many of their products.Today the company uses an ordering quantity based on experience which is rarely updated. Furthermore the operations are performed in both the company?s own engineering workshop but also an external workshop.The purpose with the report has been to check whether an updating of today?s batch shaping and ordering system can mean simpler storage control and possibly cost reduction.

Gryaab wants to research their possibilities to become independent with electrical energy and the possibilities to enrich, upgrade biogas. The use of methane rich gases like biogas and natural gas is today low in Sweden compared to major parts of the world.

Inventering och bedömning av förorenade områden inom division Energi, Tekniska Verken i Linköping

This thesis was commissioned by Tekniska verken, Energy Division with the overall aim to investigate the concept of environmental debt and what it means for a business. Furthermore, a sustainable risk and responsibility investigation shall be carried out on the concerned areas. Finally, the priority areas shall be highlighted and proposed actions presented. The Swedish Environmental debt concept was presented in 1992 by Arne Jarnelöv. Environmental debt is defined as restoration costs for environmental damage. In the early days the concept did not take into account who was responsible, but the environmental debts was regarded as a humanity debt to future generations.

Hur lokal bioenergi kan bidra till att Uppsala kommun når klimatmålet 2050

The purpose of this thesis was to examine how locally produced bioenergy may contribute to meet the climate target year 2050 in the municipality of Uppsala. The goal of reduced GHG-emissions from current 6,8 ton CO2-equivalents to 0,5 ton CO2-equivalents per capita and year, year 2050 is based on avoiding harmful penalties of an increased level of GHG in the atmosphere. By estimating available biomass in the county together with examining future technologies and emission factors for the substrates used, four possible future scenarios has been developed focusing either on electricity generation or production of biofuels. GHG-emissions of year 2050 have been calculated using the software LEAP. The conclusion is that bioenergy, depending on how it is integrated in the energy system, may reduce greenhouse gas emissions between 0.6 ton CO2-equivalents and 1.4 ton CO2-equivalents per capita or 12% to 25% compared to 5.5 ton CO2-equivalents in the reference scenario 2050. The greatest reduction is obtained if biofuels are produced in combination with energy efficient heat requirements in buildings..

Centrala logistiska faktorer i en förädlingskedja för massproduktion av träpellets : Fallstudie på Kopparfors Pelletsfabrik

This examination work aims to describe how a supply chain around the biggest pellets factory in Sweden will be configured in a logistic perspective. The plant and associated infrastructure are in the building phase and will have production start on the 2 November 2009. The key question that is set in this examination work is to recognize the logistic processes which are essential for an effective flow of materials and information that link the source of supply with the ultimate customer. In order to get the answer, a flowcharting of these supply chain processes is required for understanding the pipeline activities such as input and storage of raw material, the production system and the output of pellets to the customers. The basis for this supply chain map is a model-based representation of these logistic processes and activities that are involved around the pellets factory.
