Stress test methods : a potential approach to hurry up shelf-life tests on oat products

The aim of this Master?s thesis was to find out more about the delimiting quality- and shelf-life parameters over time for liquid oat-based products. According to that, to present applicable subjective and objective shelf-life test approaches at accelerated conditions. The study aimed to gain a deeper knowledge concerning the general and accepted way of performing accelerated storage tests. This study focused especially on products, which suffer from quality failure caused by oxidation, such as liquid oat-based products.

Uppgradering till ISO 9000 2000 : Monteringsfabriken, SAAB Automobile AB

Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

Solvärme med säsongslager i Lyckebo

The purpose of this thesis is to investigate and clarify the facts surrounding one of Vattenfall's district heating plants; The "solar field" and associated rock cavern in Lyckebo, Storvreta. The plant was built in the '80s by the formerly municipal utility,Uppsalakraftvärme AB, as an experimental building. A ground water filled cavern would serve as seasonal storage of solar heat from an adjacent solar field. Since both the energy company and the facility itself has undergone major changes over the past 30 years, there was a great need to gather facts in order to provide a picture of its current condition and potential for continued use. The thesis investigates the plant's history and problems with the rock cavern losses, and how the operation developed. It also presents the calculations regarding the possibilities of again supplementing the facility with solar energy - which is not the case today - as well as the economic conditions for it. Regarding a re-launch of solar energy, primarily a concentrating solar collector has been studied, as it has the advantages of an integrated control system.

Hantering av elektronik komponenter under Last Time Buy

The purpose of this thesis project was to study how different companies are working with LastTime Buy and through that study propose improved ways of working with this for Scania CVAB. The project aimed at studying the work processes from three different perspectives:decision models, quality aspects and liability aspects between companies.To study this, qualitative interviews with one or several representatives from differentcompanies that are affected by or involved in Last Time Buy were used. Representatives wereselected partly from Original Equipment Manufacturers, suppliers, component manufacturersand companies offering third part solutions for Last Time Buy. The companies also reflecteddifferent industries. The interviews aimed to create an understanding for the methods used atthe different companies but also the ways of thinking and the knowledge behind the choice ofthese working methods.The analysis shows that the Original Equipment Manufacturers used very similar decisionmodels for Last Time Buy, but that external factors or the company strategy made them reachdifferent results.

Ämnesindexering av spelfilm

The aim of this thesis is to examine possibilities concerning subject access to fiction film, i.e. appropriate ways to describe fiction film for subject retrieval. Problems regarding subject indexing in general, and subject indexing of fiction film in particular, are identified, as well as the uniqueness of fiction film and film genres. Four types of subject aspects are discussed: form and genre, fictitious characters, setting, and general topics. Several guidelines, form- and genre lists, and subject headings lists are examined and treated as potential indexing tools.

Intranät och dokumenthantering vid ett mindre till medelstort företag En fallstudie

The aim of this masters thesis is to learn how an organization has solved its information management via intranet and document management. The purpose is to identify what different types of information are made available via an intranet, how this information is structured and what functions the intranet includes. Conventions, directions and advice about intranets and document management were studied, with the purpose to compare whether the systems of the company correlate with these. Other issues considered in the thesis, are how the employees of the organization use the intranet and how the document management is organized. To get an understanding of these questions the structure and functions of the intranet were studied empirically and a questionnaire on what the employees need and use, concerning the intranet, was sent out to 130 employees.

Förutsättningar för småskalig solelproduktion i Australien

The study aims to investigate the feasibility of small-scale electricity production with solar electricity systems, also known as PV (photovoltaic) systems, in Australia. Due to the global warming, sustainable energy has in recent years become an increasingly important issue, both internationally and in Australia. With one of the largest dependencies on fossil energy sources in the world, the country's abundant solar radiation is a possible solution to this issue.Both the technical and the economic feasibility of small-scale PV systems were investigated. On the technological side, the electricity generation, distribution and consumption systems were studied. On the economical side, the parameters that drive the profitability of a PV investment were investigated.

...alltså vad menar du egentligen med informationssökning?... : En undersökning av lärarstudenters utbildning i informationssökning och skolbibliotek

The purpose of this Master's thesis was to examine how and what trainee teachers are being taught about information seeking and school libraries related to problem-based teaching method in compulsory school. The questions at issue were: How have trainee teachers learned about information seeking? How have trainee teachers learned about using school libraries? We also wanted to know which education they have got in information seeking and school libraries. We examined this through both literature and empirical studies. We used a qualitative method in order to answer the questions at issue.

Trafikinformation som når ut : En studie om nya kanaler för störningsinformation i trafiken

The Swedish traffic system is congested, especially in the urban areas; travellers face daily growing traffic jams and delays in public transport. In a congested traffic system, travellers need support to make smart and sustainable decisions and one such tool is traffic information.One issue today is that too few travellers use traffic information in support of their travel. Research shows that travellers would see great value in receiving the information; however current systems do not meet their requirements. This is a problem since the society would benefit greatly from a well functioning traffic information system.In this report, a number of channels that can be applicable for providing traffic information will be explored, with particular emphasis on interference information.The information channels are analyzed based upon the needs and requirements of the society and the traveller. The thesis of the report is: the more of these needs and requirements are met in a channel; the better is the channel to use for traffic information.

Usually it is in the description of what is to be acquired as the information is incomplete, but also in knowing when Quality Control-functions (QC) is supposed to be used.The aim of this work is to describe and analyse the material acquisition process.

Ledtidsreducering vid Saab Training Systems Ab : Lead time reduction at Saab Training Systems AB

Detta examensarbete är utfört på Saab Training Systems AB i Huskvarna. Saab Training Systems utvecklar, tillverkar och säljer kompletta militära träningssystem.Syftet med arbetet var att minska ledtiderna, då korta leveranstider blir ett allt viktigare konkurrensmedel. Arbetet innebar en kartläggning av nuvarande reserv- och reparationsflöde samt att identifiera problem och komma fram till förbättringsförslag.Vidare har vi studerat reservdelslagrets lagernivå och dess kapitalbindning.Arbetet genomfördes med hjälp av intervjuer med berörd personal, observationer, enkätundersökning samt statistiska studier. Vi har även arbetat med Supply Chain Operations Reference Model som är en öppen referensmodell med vars hjälp man kan kartlägga, förändra och optimera sin verksamhet.Saab Training Systems har som mål att ledtiderna för reservdelsflödet och reparationsflödet skall vara 14 dagar, men i själva verket är det inte så. Dessa ledtider är idag längre, hur långa är dock oklart.De långa ledtiderna beror främst på att i flödena förekommer det mycket passiv tid.

Hur söker användare kinesiskt material i LIBRIS: ?????

The purpose with this thesis is to research what function the National Library Catalogue of Sweden (LIBRIS) has as an information resource for Chinese language material. How is LIBRIS used as an information resource seen from the point of view of a users specific language need. This will be exemplified through an empirical survey of three user groups with different prerequisites concerning their knowledge in Chinese. Group A were beginners and had studied Chinese for one year. Group B were advanced students who were studying their third year of Chinese.

Sänkt returtemperatur : Potentiell besparing i fjärrvärmesystem

Optimizing energy systems is, in Sweden, as in many other countries, of growing interest. District heating systems are no exception. In 2012, 285 out of 290 municipals in Sweden had district heating in use and the majority of these systems have a higher return temperature than that which is possible with an error-free substation of day current technology. To, when possible, lower the return temperature is a way of increasing the effectiveness of the district heating system.This study means to investigate, through simulations and calculations, how big of a reduction in production cost a lower temperature in the city of Ystad?s district heating system would correspond to.

Uppföljning och analys av Stockholms stads solcellsanläggningar

During 2007 the City of Stockholm installed five grid connected photovoltaic systems. The aim of this master thesis is to quantify the amount of produced energy and recommend routines to collect and analyse production data, to make production data accessible by the public and to gain experience for future installations.The total amount of produced energy until March 2009 is 227 000 kWh, with an annual rate of 150 000 kWh. The expected annual rate was 148 000 kWh.All system owners are positive about their plants and see economical benefits in scaling up such systems.The installations need very little attendance and maintenance, however it is recommended that an alarm function is installed for automatic feedback in case of a system failure. All future systems should be inspected during full operation to determine if the actual capacity is matching the installed capacity..
