Utvärdering av digitala provtryckssystem
Six different Digital Proofing Systems from three different techniques have been evaluated as totechnique, printing quality, economy and usability. Digital proof from two paper qualities, coatedand uncoated, has been compared with references printed in offset, to see how good they match eachother. Only two Proofing Systems manage to print on reference paper. The other Proofing Systemsuse special paper for digital proof.Measurements and visuell judgement show that the Digital Proofing Systems visualise referencepictures with quite good quality. Proof optimised for coated paper visualise the colours with goodresult.
Webbsystem för matprisjämförelser
This is a thesis project in the field of information technology which begins by evaluating existing food price comparison systems and subsequently aims to design an improved, web based system for said purpose. The system features interfaces for price reporting, price comparisons as well as various search and review functions. The objective is to create a system able to compete with existing price comparison systems, which requires careful selection of products that can be found in all foodstores that also represent different households; a user-friendly price reporting and price comparison interface and an efficient tool for ensuring the validity of reported prices.The designed system features a more accurate formula for calculating average prices in events where the real price is missing; a more reliable security mechanism forv alidation of reported prices and a more comprehensible interface for viewing price reports, reporting prices, reviewing stores and products in comparison with existing systems. The system does, however, suffer from some optimization issues primarily in the form of inefficient database modeling; SQL queries and JavaScript code although testing has shown that these shortcomings do not hamper overall performance to such a degree that usability is compromised. Further usability testing performed on the system with five test subjects shows that a high level of overall user-friendliness has been achieved even though some special features, such as the detailed report containing price information per product for each store need to be improved.It is not possible to say at this time whether or not the designed system will be able to compete with existing ones or if the very concept of food price comparisons per se is viable in terms of profitability and marketability.
Lean Information Lifecycle Management : Värdeskapande informationshantering för Bild- och Funktionsregistret inom Västra Götalandsregionen
Mängden information och informationskällor ökar exponentiellt med tiden och metoder för hantering av information blir därför allt mer relevanta. Privata och offentliga organisationer uppmärksammar allt mer behovet av en strukturerad och effektiv metod för att kunna hantera denna oundvikliga informationstillväxt.Uppsatsen syftar till att identifiera potential att förbättra det nuvarande informationssystemet inom Bild- och Funktionsregistret genom att tillämpa en Information Lifecycle Management-strategi utifrån Leanperspektivets värderingar. Studien inleddes med en litteraturstudie där de huvudsakliga Lean- och Information Lifecycle Management-principer definierades för att skapa ett teoretiskt underlag för vidare studier. Den efterföljande empiriska fallstudien av Bild- och Funktionsregistret och Sahlgrenska Universitetssjukhuset genomfördes för att få en ordentlig och tydlig bild av den organisationen och dess informationssystem.Fallstudien identifierade de huvudsakliga problemen och möjligheterna i den nuvarande organisationen. Problemen i form av organisatoriska brister, bristande användning av systemet och växande informationsvolymer bemöts genom införande av klassificering, strategisk integration och hierarkisk lagring av information.
Termomekanisk analys av svarvstål : Volvo Aero Corporation
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.
Hur hanterar institutioner en miljö med blandade Operativsystem?
The purpose of this thesis is to investigate if there are environments that use
some kind of central authentication system within institutions/schools. The
hypothesis is that an institution not using a form of central authentication
service has more need for maintenance and as such is considered a higher cost
for the organization.
The gathering of data has been done through interviews with technical personal
at Blekinge Tekniska Högskola and Linköpings Universitet. Based on the
technical background of the authors, and the system limited to discussing
Windows and UNIX operating systems, a discussion and analysis of the systems
working today has been done, with emphasize on the hypothesis..
Testeffekten som medel för att förbättra läsförståelse?
Swedish school children exhibit deteriorating knowledge results in terms of reading comprehension. Previous research shows that a method to increase the level of knowledge is the use of evidence-based learning techniques. Test based learning generates what is commonly referred to as a test effect, which proved to strengthen the relationship between learning and memory, as well as being applicable to various test formats. The purpose of this study was to investigate whether test based learning, in terms of learning english words leads to increased performance in a reading comprehension test, more specifically a cloze test. The study was based on a within-group design and was conducted three times over four weeks.
Vägen till god användbarhet : En fallstudie inom informationsarkitektur med fokus på ett informations- och filhanteringssystem
Since Internet has become a more important and more certain source of information the user require greater and more demands than ever before on the layout and function of different web pages. When search engines gives us the opportunity to millions of hits in just a fraction of a second it?s essential to optimize the structure and architecture, which forms the foundations of all the content. In a time when a company?s digital footprint plays an important role for the costumer and the transmitter it?s of utmost importance to have a steady, well-structured foundation to build new platforms of information on.But how do you manage to build a good foundation? Some of the most important key elements in Information architecture are Organizing, Navigation, Search and Labeling.The aim of this study was to create guidelines for a user-friendlier interface, by analyzing the principals and gathered data.
Mikroproducenternas påverkan på Elinorr
The Swedish energy system will be influenced by many future changes, such as energy and climate policy objectives. The installation of more renewable electricity could increase by using solar energy. Over the recent years, grid-connected photovoltaic (PV) systems have increased dramatically in Sweden, partly due to various support systems and compensation models. These support systems have been designed to make it easy for individuals and businesses to invest in self-generated electricity and thus contribute to the transformation of the energy system.The introduction of a higher proportion of solar energy may in turn affect the Swedish electricity system. This could mean that the electricity companies will be facing a number of changes in the near future.
The welfare of the laboratory mouse : comparison in development of mouse pups in three different individual ventilated cage (IVC) systems
Today the individual ventilated cage system (IVC-system) is a commonly used housing system for mice in research facilities. IVC systems have HEPA- filters and are designed to control both supply and exhausted air at cage level, as well as temperature and relative humidity in the cages. This creates an optimal environment for the mouse and at the same time a protection against the risk of cross-infection between cages and the outside environment. The aim of this study was to evaluate the health and welfare of breeding females and pups of two different strains of laboratory mice (NMRI nude mice and C57BL/6N) in three different kinds of IVC-systems; Arrowmight, Allentown and Tecniplast. The NMRI nude (Nu) females gave birth to 18 litters in Allentown, 16 litters in Arrowmight and 15 litters in Tecniplast.
Google Scholar eller Scirus för vetenskapligt material på webben? En utvärdering och jämförelse av återvinningseffektivitet.
This thesis evaluates and compares the retrieval effectiveness of the two search engines Google Scholar and Scirus, which both specialises in indexing scholarly material on the web as well as journal articles. Thirty search queries are used and the first twenty retrieved documents for each query are examined for topical relevance and scholarly content. The search queries are based on legitimate information needs taken from a scientific questionbox on the web. Queries are expressed with advanced search operators and are the same for both search engines. Precise relevance criteria are set up and a binary scale is used when judging.
