Praktiska effekter av begreppsförvirring för en databas konceptuella design : En fallstudie om databas- och begreppsmodellering

Company X develops a laboratory information system (LIS) called System Y. The informationsystem has a two-tier database architecture consisting of a production database and a historicaldatabase. A database constitutes the backbone of a IS, which makes the design of the databasevery important. A poorly designed database can cause major problems within an organization.The two databases in System Y are poorly modeled, particularly the historical database. Thecause of the poor modeling was unclear concepts.

Double integrating spheres: A method for assessment of optical properties of biological tissues

The determination of the optical properties of biological tissue is an important issue in laser medicine. The optical properties define the tissue´s absorption and scattering behaviour, and can be expressed by quantities such as the albedo, the optical thickness and the anisotropy coefficient. During this project, a measurement system for the determination of the optical properties was built up. The system consists of a double integrating sphere set-up to perform the necessary reflection and transmission measurements, and a computer algorithm to calculate the optical properties from the measured data. This algorithm is called Inverse Adding Doubling method, and is based on a one-dimensional transport model.

New Aid Management: En kritisk analys av new public management-ideal i styrningen av Sveriges internationella bistånd

Since the 1980s, the management philosophy New Public Management has resulted in major changes in the public administration system in several countries, especially in the West. A market oriented approach and an increased focus on performance measurement are ideals that are salient in these changes. The aim of this bachelor thesis is to examine the management philosophy?s influence on international relations through a critical analysis of some of its ideals in the management of international development cooperation, where effectiveness, quality, and results have been new dominant concepts. Through a qualitative content analysis of a Swedish Communication from 2014 ? the Aid Policy Framework ? and a debate in the Swedish parliament where this Communication was discussed, different themes that reflect the strategy of so called results based management in Sweden are identified.

Reglering av vridbord

This report describes a master thesis performed at Saab in Arboga. The main purpose was to build a controller for a system containing a turn table and an antenna beam. The idea is to use this system on a boat where it will be exposed to position disturbances due to waves. The desired behaviour is that antennas placed on the antenna beam should point towards the same target all the time. To solve this problem the system has been modeled and simulated in Matlab and Simulink.

Product/Service-Systems ? en litteratur undersökning för att definiera och differentiera forskningsområdet

Inom industrin används olika testmetoder för att uppnå hög kvalitet i mjukvarukontrollerade system. Kvalitetskraven är särskilt höga för säkerhetskritiska system t.ex. styr- och reglersystem i fordon. I det här examensarbetet används två analysmetoder (Fault Mode and Effects Analysis och Fault Tree Analysis) för att ta fram ett nytt säkerhetstest för ett broms- och växlingssystem som Scania tillverkar. Det studeras även hur formella metoder kan användas för att ytterligare öka kvalitet ochh tillförlitlighet.

Leveransprecisionsmätning : en företagsstudie på Sanmina-SCI

Performance measurements have become very important tools for companies because of ever increasing global competition in today?s market. Delivery dependability is one of the three most important performance measurements for companies to focus on and that makes this analysis, of the dependability, both very interesting and up to contemporary. In this rapport different aspects of delivery dependability will be dealt with, and a weight will be on what to measure and how to measure it together with how to present the outcome of the measurements. A discussion has also been held regarding what goal the company should have on its dependability.

Automatiskt bygge av FUS39A

This paper describes the design and implementation of an automated build system for the JAS39A simulator FUS39A at HiQ:s offices in Arboga. The assignment was to automate the process in which modules are built; the simulator is composed of a number of modules which are built manually at the end of each week, this process takes about a day of manual labor. The system can automatically build a module as either a scheduled service or by manual invocation. The system contains functionality for reporting the build results to any given recipient by e-mail. The purpose of the system is to free up the time put into manually building the modules for better suited tasks by automating the build of FUS39A.The assignment was split into two parts, an analysis part where information of the old system was gathered, tools and methods were chosen and the new system was designed.

Undersökning av IT-stöd för ett av Europas snabbast växande telekomföretag

Allt fler organisationer väljer att förbättra och förnya sin verksamhet genom att använda informationssystem. Verksamheter idag har blivit allt mer beroende av IT- stöd i form av system samt webbapplikationer, eftersom det automatiserar och effektiviserar arbetsprocessen. Verksamheter med ett fullt fungerande IT-stöd leder, lyfter och styr företaget framåt i utvecklingen. Nyttan av ett IT system kan mätas då systemet är anskaffat och befinns i en förvaltningssituation. I förvaltningssituationer används IT system vilket kräver att dessa underhålls och omskapas efter verksamhetens utveckling.Studien syftar till att kartlägga alla IT-system och webbapplikationer för Tele2 Butikerna AB samt för varje system identifiera användare, accessroller, funktioner, förvaltningsresurser och förbättringsområden.

Generellt mät- och styrsystem

Examensarbetets syfte var att skapa ett generellt mät- och styrsystem som är möjligt att fjärrstyra över Internet. Systemet består av en kontrolldator och ett antal separata moduler, vilka var och en realiserar någon typ av mät- eller styrfunktion. Användningsområdet för ett sådant system är brett; det kan exempelvis användas inom automation av bostäder, för process-övervakning och styrning inom tillverkningsindustrin, eller inom under-hållningsbranschen.Eftersom ett fullt utbyggt system kan bestå av ett drygt 100-tal olika mo-duler, är det här examensarbetet av praktiska skäl begränsat till att rea-lisera en handfull av dessa. Då systemet är enkelt att skala upp, är den be-gränsningen i antalet realiserade moduler i prototypsystemet inget som påverkar de erhållna resultaten. Exempel på storheter som kan övervakas är temperatur, avstånd, lufttryck och ljusstyrka.

Debatten om övergången från SAB till DDC ? Hur ser den ut?

In 2008 the National Library of Sweden decided to give upClassification system for Swedish libraries and start using DDC(Dewey Decimal Classification) from January 1 2011. Thisdecision has influenced the whole Swedish library system and longbefore the National Library of Sweden took this decision thequestion had been thoroughly discussed and debated in Librariancircles.The aim of this thesis is to find out which arguments have beenintroduced in the debate, if the discussion has changed from beforethe decision to go over to DDC was taken to after wards, and if sohow it has changed. My thesis will discuss the following threequestions:? Which arguments were brought forward in the debate,both for and against a transition?? How has the debate about the Swedish libraries?transition from Classification system for Swedishlibraries to DDC changed from before the decision ofthe Royal Library was taken to after?? What conclusions can you draw from the debatewhich has been led about the transition to DDC?The empirical material consists of six articles dealing with thetransition to DDC and in the analysis of this material I have used atext analyses, analysis of. The analysis shows that more or less thesame arguments for and against have been used in practically allthe articles, and the debate has not changed very much.

Vilken funktion har belöningssystemet i en organisations ekonomistyrsystem? : en jämförelse mellan två storbanker

Two of Swedens´s major banks, SEB and Handelsbanken, which appears in the same industry and have similar strategy. Both banks can achieve a similar result despite the fact that their reward system looks quite different. An issue that arises from this observation is the relative reward system to the rest of the economy control system.Our purpose of this paper is therefore to examine the reward system in the organization's financial management systems. We wonder if the reward system may be a function of economic control system, or part of the system, or perhaps made independent of the system and then gradually adapted?In our study, we choose to assume a reward system has three functions to manage, motivate and compose the employee group.

Klassifikationssystem på webben: Traditionella och nya

The aim of this thesis is to investigate the opportunities of classification of web pages. Two classification systems are compared; a library classification system traditional and a system that is developed for use on the web new. UDC is chosen to represent the traditional systems, and Yahoo! represents a so called new system. UDC is used by NISS Directory of networked resources, which is a directory that uses the system for organisation of electronic resources. Both systems are analysed from two different perspectives, a multidisciplinary and a timeperspective.

Metoder för trust : Hur praktiker arbetar för att bygga förtroende till knowledge management-system

This thesis examines how knowledge management professionals use trust as a component in the creation of knowledge management systems, and what methods they use for building trust.Adopting a grounded theory approach, interviews with 8 knowledge management professionals active in different industries served as the base for an analysis that identified trust to be the single most important common factor in the data. The concept of trust used by the informants was identified as relating to the knowledge management system itself, rather than other users, employees or groups in an organisation.Building trust, the KM-professionals mainly focused on three methods: simple solutions, system superiority, and implementation security. Using these methods, the KM-professionals seek to ensure system trust by creating opportunities for users to obtain positive experiences of using the system, and thereby generate a foundation for a trust-based relationship between the user and the system..

Utveckling av modellbaserad reglering i kommersiella styrsystem

In industrial control systems PID-control remains the prevalent strategy, also for processes that would benefit from model based control. The purpose of this thesis is to evaluate whether model based control can be readily implemented in an industrial control system. To this end a simulated surge tank with a simulated industrial control system is studied. For evaluation two scenarios with specified objectives are selected.Following a review of LQR and versions of MPC, Predictive Functional Control (PFC) is considered the most suitable for implementation. PFC is a form of MPC developed with industrial applications in mind and therefore has several advantages for implementation in an industrial control system.
