Multivariat tolkning av sensordata
Undersökningens syfte har varit att ta del av likheter och skillnader i gymnasieelevers uppfattningar om Matematikvägen, utifrån frågeställningen ?Vilka upplevelser har eleverna av Matematikvägen??. Metoden för undersökningen har varit intervju.Matematikvägen är ett grepp att möta elever med ett stort matematikintresse inför och på gymnasiet. Detta görs genom att eleverna får möjlighet att läsa ungefär halva gymnasiets Matematik A redan under sista terminen på grundskolan. Eleverna ligger på så sätt en termin före de som läser matematiken på normal fart vilket innebär att de det sista året på gymnasiet kan välja att läsa linjär algebra på högskolan.
SATSA FRISKT FOR LIFE : En komparativ studie om kundens köpbeteende inom träningsbranschen
Children's Need In Focus (BBIC) is a processing and documentation system used in child welfare cases to investigate, plan and monitor interventions. The BBIC has had a breakthrough in Sweden and out of the country's 290 municipalities, there are 284 that use the system daily as a tool in cases involving children. The purpose of this study was to examine how social workers experience the BBIC as a working system and what strengths and weaknesses there are in the BBIC concept. We wanted our study to examine how the BBIC could possibly enhance the quality of childcare matters, but also how the BBIC could potentially increase children's participation in cases. We have performed qualitative interviews with eight social workers who work in four different municipalities where the BBIC is applied daily.
Studie av skyddsavstånd mellan bergvärmeanläggning och skyddsobjekt i ett vattenskyddsområde
During installation and operation of a geothermal heat pump system leakage of an antifreezing agent can appear in a borehole and leak out in surrounding groundwater. To guarantee high quality drinking water for generations to come Sweden has dedicated some areas as water protection areas. The local authority gives permits for the installation of heat pump systems within water protection areas. Before giving a permit the local authority makes an evaluation of the risks involved in installation and operation of the system within the area. By keeping a certain distance between the protected object in the area and the heat pump system the risk of polluting the protected object with an anti-freezing agent can be reduced.This thesis makes a comparison between three different methods of calculating an appropriate distance between the protected object and the heat pump system.
Datorbaserad analys av enzymdesign för Diels-Alder reaktioner
This thesis has been focused around the Diels Alder reaction with the goal to design an enzyme catalyzed reaction pathway. To achieve this goal computer aided enzyme design was utilized. Common traditional methods of computational chemistry (B3LYP, MP2) do not do well when calculating reaction barriers or even reaction energies for the Diels Alder reaction. New calcu- lation methods were developed and tested. This was the focus of the first part of the thesis, by choosing a small system, extensive and heavy calculations could be done with CBS-QB3.
Kvalitet på införande av MPS-system
Företag och organisationer har sedan industrialismens första år arbetat med att försöka effektivisera produktionen. Effektiv produktion leder till billigare produkter, som i sin tur leder till ökad försäljning. Ett bra hjälpmedel för att uppnå denna effektivisering är införande av ett MPS-system. Systemet hjälper till att planera, organisera, samordna, styra och kontrollera materialflödet i företaget.Införandet av detta system är dock inte alldeles trivialt. Många experter säger att implementering av MPS-system är svårare än att introducera en ny produkt eller att etablera sig på en helt ny marknad.
Information om kundval, en förutsättning för valfriheten? : en studie av hur tre kommuner arbetar med informationsspridning om kundval inom hemtjänsten
This paper studies, from a client perspective, how three Swedish municipalities work with information about a voucher system in homecare. The paper is a qualitative study using structured informant interviews and analysis of documents. The interviewees are responsible of information about the voucher system in the municipalities. The studied documents describe and clarify the voucher system of the municipality. Neo-institutional organization theory is used to analyse the result.
Att skapa ett informationssystem ? en holistisk ansats
This thesis aims to discuss how an information system and its users may adapt to each other. The main discussion is how to create an information system that is adaptable without losing its organising properties. The thesis uses a holistic approach to the topic and the areas being dealt with are information architecture, interactive information retrieval and information searching. The practical work consisted of constructing a database for Autoliv?s Research and Development branch.
Utvärdering av taxonomi och systemstöd för riskbaserad analys inom den svenska Luftfartsinspektionen
The Swedish Aviation Safety Authority has decided to standardise a classification system for reporting deviations found in inspections. The purpose of a classification system is that similar deviations always should be reported in the same way since this will enable better decisions regarding different risk areas. The inspectors are therefore constrained to use a standardised classification system and are not free to use their own words when reporting deviations. A hierarchal classification system with predefined phrases is in aviation referred to as taxonomy. Taxonomy is already in use when reporting accidents and incidents but not when reporting deviations found in inspections.
Golfbollstvätt
During the past few years an increased attention has been paid to environmental issues in the construction and property sector in Sweden. In order to simplify the work with these issues a Swedish environmental certification system for buildings called Miljöbyggnad has been developed. This thesis aims to investigate the opinion of a selected number of selected property owners of Miljöbyggnad. From that basis recommendations and actions for the future work with the system will be presented.The investigation has been conducted through personal interviews with five property owners. The main issues that the interviews have been based on are their purpose, experiences, perceived complications and future prospects in terms of certification using Miljöbyggnad.The system intends to be cost-effective, simple and to offer a relevant environmental assessment of buildings and the result from the report indicates that this is largely fulfilled.
Modellering av reserv- och nödkraftsystem i JAS 39 Gripen
Simulation is a vital tool during development of JAS 39 Gripen, since money and time can be saved.The Auxiliary and Emergency Power System, AEPS, is a subsystem of the secondary power system in Gripen. It has the function of providing the aircraft with electrical and hydraulical power before activation and after deactivation of the main engine. The system also functions as backup in case of a safety critical problem in the main power supply system. The system basically consists of a control unit and an auxiliary gearbox. The gearbox is driven by an air turbine.
Skriftspråksutveckling i förskoleklassen
The aim of this essay was to investigate how teachers in the preschool class work with literacy. How do they justify the methods used to develop children's literacy abilities? I also wanted to know to what extent teachers enable multimodal approaches within written language practices. My study considers the impact teachers' professional identity has on working methods in the preschool class. I hope this essay will help teachers reflect on their learning approach.
I gathered information by interviewing three preschool teachers and one compulsory school teacher for the early years working in three different preschool classes in three different schools.
Automatisk bedömning av reglerkretsarsprestanda
In this thesis, a computer program that in a simple way can calculate the performance of control loops at the refinery Preemraff Lysekil has been created. The computer program has been adapted to the environment at Preemraff Lysekil. Theories for evaluation has been studied in aspect of reliability and of automatic implementation. The evaluation has been carried out from data collected directly from control loops at the refinery and from simulated control loops with implemented errors. Among the studied methods are Harris index and Stattin´s oscillation index.
Säkerhetsutvärdering certifikatserver i stället för aktiva kort
Business and organizations use computer network in a greater extension than ever before, especially for business-critical use. That increase the demand of security for all systems, both against internal and external threats. The demand on the authentication method used today increases. Today they normally uses password or some kind of smart card. I will performa literature study that will investigate the possibility to increase the security in authentication of users without the use of extra hardware.
ABC och ekonomisystem : En studie av Volvo Construction Equipment Components AB
The accounting information system comprises budgeting, accounting, and costing. The accounting information system has, traditionally, constituted an integrated system where the different elements collaborate. If ABC is introduced this order is disturbed, since ABC is based on another logic which cannot easily be integrated with budget and accounting. ABC, therefore, is usually used parallely to the conventional costing method. There are, however, companies that have taken its ABC one step further by letting it replace the old costing model and integrate it with the accounting information system.
