Konvertering av CRM-system från ASP till ASP.NET
S2 CRM is a Customer Relations Management system built in classic ASP that runs on a web server servicing customers with varying needs. The purpose of this thesis work is to convert parts of the system to the web development environment ASP.NET. The purpose is also to gain knowledge of the framework itself. The ASP.NET environment is compared with another framework, JBoss Seam, in order to understand the differences and to evaluate the possibility of using another framework than ASP.NET, when building the new system. The outcome of this comparison is that although JBoss Seam is just as good, and in some aspects better than ASP.NET, the use of ASP.NET simplifies the continuation of development on the S2 CRM product.

The scope of this diploma work is to develop a simulation model ofBoiler 5 at Mälarenergi AB. Boiler 5 is a circulated fluidized bed boiler that was taken into service inyear 2001. Among the included parts in the boiler are cyclone, convection part andINTREX-chambers.
Adaptiv temperaturreglering av bostadshus
The control of indoor temperature must be able to handle large time constants and both measureable disturbances like outdoor temperature, and non-measurable disturbances, like waste heat from appliances. Due to cheaper microcontrollers (small computers with designated tasks) with better performance, more advanced and computation-demanding methods for control can be used.In this thesis, Generalized Predictive Control (GPC) has been implemented and tested on a theoretically derived model of a house. GPC states that a model of the system is estimated in every sample, and the control is carried out simultaneously, based on predictions of the model. Disturbances like solar radiation can be estimated and used in the control as well. The control signals are determined by quadratic programming, which makes it possible to consider conditions, for example limitations on the control signals.GPC requires a number of parameters to be defined, like model order and control signal penalty, but is relatively robust for variations in them.
Språk och integrering i F-3 : En kvalitativ undersökning där lärare i F-3 diskuterar och reflekterar språkets och integreringens betydelse för elevernas utveckling
The aim of my study is to see how teachers in the early primary school are working to teach all their pupils based on how different ethnicities, cultures and multilingual differences reflect on their work places ? the classrooms. I've also contacted the county, were the schools are located in, so I could see what system they are using and how it affects the society.The Swedish society is influenced by different cultures, multilingualism and ethnicities the more time passes, which means that teachers all around need to integrate their pupils in the system so they can better adjust to how the Swedish school system works and be prepared for adult life. Teachers need to concentrate intensely on how they should guide the pupils in their specific class so they can reach their full learning potential and reach the knowledge criteria set by the Swedish school system.I contacted the board of education and to set up a meeting so we could discuss my project. During the meeting I asked the representative how they believe this matter should be handled.
Undersökning av koppars effekt som antibakteriellt agens i tyg
Syftet med denna studie var att undersöka den antibakteriella effekten hos ett polyestertyg med tunna invävda koppartrådar. Frågeställningen som skulle besvaras var ifall koppartyget hade en baktericid eller bakteristatisk effekt. Koppartyget är ännu i prototypstadie och om det visar sig ha antibakteriella egenskaper är det tänkt att användas inom klinisk verksamhet för att förhindra bakterietillväxt i sår och andra känsliga lokaler. Koppar är ett essentiellt spårämne, men har också antimikrobiella egenskaper som utövas genom ett brett spektra av mekanismer där skador på cellmembranet är en av de viktigare. Metoderna som användes för att inokulera bakterier på tyget var absorptionsmetoden, där en näringsbuljong innehållande Staphylococcus aureus ATCC 6538 pipetterades på tygproverna, och transfermetoden där tygproverna trycktes mot en agar som racklats med peptonsaltlösning innehållande S.

Flödesmätning i vattenkraftverk : Studie av alternativa mätmetoder
Flow measurement is one of the greatest challenges in order to calculate efficiency in hydropower. Most hydropower plants in Sweden use differential pressure methods for flow measurement. These methods are dependent on constant conditions in the waterways. A change in these conditions, like turbine improvements, prevents differential pressure methods to verify efficiency improvements. Since efficiency improvements can?t be verified by one measurement system, another method, which isn?t affected by changing conditions, can be used.
Mekaniserad ungskogsbehandling för röjning och skörd :
Earlier attempts at mechanising pre-commercial thinning have been met with varying degrees
of success. Most attempts have been based on techniques where residual stems are straddled.
Early treatment is essential to limit damage on residual trees. One part of the present study is an evaluation of mechanised pre-commercial thinning using the new Vimek 404R. Vimek 404R is a fairly small machine that permits selective removal of stems, making it potentially suitable also for areas overdue for pre-commercial thinning. The study established the level of performance for the machine, as well as the improvement needed to make it an economically viable option.
Kappa Control with Online Analyzer Using Samples from the Digester's Mid-phase
In the pulp industry, digesters are used to disolve lignin in wood chips. The concentration of lignin is measured and is called the Kappa number. In this thesis, the question of whether an online Kappa sensor, taking samples from the mid-phase of the digester, is useful or not is analyzed. For the samples to be useful, there has to be a relationship between the measured Kappa at the mid- phase and the measured Kappa in the blowpipe at the bottom of the digester. An ARX model of the lower part of the digester has been estimated.

Konstruktion av current conveyors via makromodellering
A current conveyor is an active building block that can be used to implement most active and passive components. It differs from the operation amplifier in that it uses current instead of voltage. The current conveyor also has significantly higher voltage gain over a broader frequency range. To simplify the construction of analogue circuits and increase the construction efficiency it is desirable to use a top-down methodology. This means that the whole system is partitioned into a hierarchy of subsystems.
Demonstrationsprojektets roll i framväxten av ny teknik: Fallstudier av två vindkraftprojekt
This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.
Projektmodell för införande av affärssystem : Ett konsultbolags implementeringsprocess i tjänsteföretag
Companies acquiring ERP systems are often dissatisfied with the project and therefore consultancy firms wish to make use of project models in order to achieve success in implementations. Since research on ERP implementations in service companies is limited, there is a need for mapping of critical activities in implementation projects in this line of business. Under these premises, the purpose of our master thesis is to develop a model for implementation of ERP systems, specified in activities, which can be used by mid-sized consultancy firms with mid-sized qualified service companies as customers.A literature study including project models, modern models and methodologies for ERP implementation, commonly existent activities, success factors and system development methods was carried out. Starting out with this, a theoretical model for ERP implementation was generated. In excess of this, a case study was conducted, where the implementation of the ERP system Microsoft Dynamics AX at the service company Eurostep, performed by the consultancy firm Medius, was studied.
Modellering av en panna med rörlig rost :
The aim of this master thesis was to create a dynamic model for the processes in a solid fuel boiler of the moving grate type. Another aim with the model was to keep it as simple as possible but still able to catch the dynamics of the processes in the bedplate of the boiler. The creation of the model had its origin from drying and combustion equations used in earlier modeling work of boilers. The represented model has been used to simulate different kinds of disturbances in a boiler and different ways to control the boiler. These tests show that controlling a number of parameters in the bed of the boiler is an effective way to keep the grate stable during disturbances.
