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.
Sju heuristiker för utvärdering av webb-API:er
The amount of web APIs that are open to the public is increasing fast. Both the free web APIs as well as the ones that cost money to access. Both bigger and smaller organizations, professional and non-professional developers use these web APIs to add value to their systems or use it to create new applications. This is an area study where alot of research has been done in the last few years. In spite of this there are still no user-centered evaluation methods for web APIs.
PION Patientinformation on-line en brukarorienterad utvärdering
During the past decade, consumer health information-centers have been developed at the hospital libraries in Sweden in order to meet the increasing demand from patients and their relatives concerning consumer health information. In 1993, the hospital libraries in Falun, Västervik and Karlstad launched a consumer health information database called PION. The aim of this Master's thesis is two-fold. My first aim is to describe and discuss the principles of user-oriented evaluation. In my attempt to convey the theoretical discussion into the everyday life of librarianship, my second and most important aim is to conduct a user-oriented evaluation of the database PION.
Utvärdering av ett system för Rapid Control Prototyping inom området robotstyrning
In this report a system for Rapid Control Prototyping, RCP, is evaluated through animplementation of the motor control methods Field Oriented Control, FOC, and Space VectorPulse Width Modulation, SVPWM. The evaluation emphasizes on time-consumption andresource utilization on the used hardware and on usability for of software.A new mechatronic laboratory is under development at ABB Corporate Research in Västerås. Itwill be used for both mechanical and motion control design using existing and new hardware.The control structure in a traditional robot system will be interfaced to a rapid prototypingsystem which should allow easy changes to algorithms at different levels in the system.The system designated for this project comes from National Instruments and constitutesLabVIEW Real-time and FPGA module as the software tools. The hardware is a NI Single-Board RIO (Reconfigurable Input Output), sbRIO, development board including a Field-Programmable Gate Array, FPGA, from Xilinx and a microprocessor from FreescaleSemiconductor. Graphical programming is performed in the LabVIEW environment, andthrough Xilinx tools the LabVIEW FPGA code is compiled to VHDL code.A pre-study was carried out to clarify the concept of RCP and investigate different systems forRCP and their traits.
Systematik eller subjetivitet? : En studie kring individuell lönesättning för lärare
The purpose of this study was to examine the routines of performance related pay systems in two Swedish municipal upper secondary schools. A second purpose was to examine what data was included for evaluation of a co-worker?s performance and how a principal collects data. The purpose was also to examine a principal and teachers´ view of performance related pay systems and if it was possible to note an agreement. Principals have been interviewed and teachers have answered a questionnaire to fulfil the purposes of this study.The study shows that the municipality had a good routine that included individual discussions with co-workers about their salary and had fixed municipal criteria.

Kan vi inte ha en sån där istället? : om teknisk kravställning på ett fartygsbaserat UAV-system
Detta arbete kretsar kring obemannade luftfartyg, UAV, avsedda att baseras ombord påörlogsfartyg. Regelverk och standarder tillsammans med befintliga fartygs-, helikopter- ochUAV-system utgör ett ramverk inom vilket ett scenario leder fram till grundläggande tekniskakrav för de delsystem som ingår i ett fartygsbaserat UAV-system. Kraven, som är framtagnamed spårbarhet i sjöoperativa förmågor, erfarenheter från den miljö ett luftburet system skaverka i ombord och systemexempel som visar vad som är möjligt att uppnå med dagenstekniknivå, presenteras som ett förslag till värderingskriterier och effektmått med tyngdpunktpå de krav som ställs på luftfartyget (UAV) i sig..
Utvärdering av energieffektiviseringsåtgärder på Bokelundskolan i Växjö
The purpose with this report is to examine how the implemented energy efficiency measures on Bokelundskolan in Växjö have had impact on the energy use. The measures which have been implemented are, new ventilation system, new heating system, optimized adjustment of the heating system, new windows with U-value 1.2 and lower window height, insulation under windows and in the crawl space. The school's energy use before and after rebuilding has been calculated with the calculation program, Vip-Energy 1.5.5.Calculations of energy use for the school with windows on U-value, 0.9 and 0.7 have also been done. The replacement of windows has been studied from a cost perspective. The conclusion is that the exchange of heat and ventilation system was the biggest contributor to reduced energy use on Bokelundskolan.
Vägen mot den Svenska vardagen : En utvärderingsstudie om kommunpolitikers, Arbetsförmedlingens och Invandrarservice uppfattningar kring implementeringen av Etableringslagen
This essay is an evaluation of the act of establishment (2010:197). The act is about different operators' responsibility and accountability for new arrivals to get a more effective integration into society and to speed up the new arrivals' establishment on the labor market. The purpose of this act is to get more new arrivals involved in the Swedish labor market directly. By doing so, it gives these people a possibility to become self-sufficient. This study has focus in four different operators; Employment service, Immigration service and two local politicians from Social democrats (Socialdemokraterna) and Conservatives (Moderaterna).
Studie av introduktionen av NorFor Plan för foderstatsberäkning till mjölkkor i Sverige :
NorFor is a cooperative project between the consulting organisations owned by the farmers in the Nordic countries ? Sweden, Norway, Denmark and Iceland. The project started in 2001
and the outcome, the system for ration calculation NorFor Plan and the model for evaluating the ration NorFor Evaluation, was completed in 2006. Along with NorFor Plan economical optimization are available and according to literature, the optimization will generate a 2 öre lower feed cost per kg milk, and thereby improve the profit for the farmer. The use of NorFor Plan in Sweden for feed optimization during spring 2008 has been very small.
In this study eight herds in the middle of Sweden fed half the herd according to the classical system used in Sweden and the other half according to NorFor Plan system.
Test av modeller för prioritering av förändringsförslag i Stora Enso Skog AB´s nya produktionsplaneringssystem VSOP
In order to evaluate the benefits and costs associated to investments in information technology (IT) managers need to be aware of the complexity in the nature of the task. Hence all the benefits that arise from the investment are not of pure economic character. The complexity of the task is even more obvious when managers also need to prioritize between a number of possible investments in order to fit a given budget.Stora Enso Skog AB is about to implement a new administration system to the organisation and due to that they will also implement a new standard system for the production planning process. In order to seek the modifications in the standard system that needs to be done to fit the organisations way of working, the managers have put together a reference group to seek out these modifications.The aim with this report is to identify a model that can prioritize these suggested modifications and test it practically with a group of future system users. The first part of the report is a literature study to map the existing models that are available.

Strategic Evaluation -A study of its purpose in SIDA and SADEV
Background and Problem discussion: Strategic evaluations are important as they providecrucial information regarding Swedish development assistance and recommendations on howto face problems and inadequacies found in the evaluations. Therefore, the follow up ofrecommendations is of great significance as well. Unfortunately, SIDA?s ManagementResponse system for follow-up of strategic evaluations has not been functioning in asatisfying way and needed actions have not been taken. Thus, Swedish developmentassistance has been criticised for the lack of implemented actions and the public has startedto question the work carried through by the organisations.
Vem hittar hylla Hcf.03? En studie av en alternativ hylluppställning på en barnavdelning
The objective of this Bachelor?s thesis is to investigate how the public library in Luleå has set about implementing an alternative classification system for its children's books section and to explore why this was done. We wanted to investigate both how they have adapted the new system to the children's own way of seeking information and the library personnel's experience of using the new shelving system. We have done seven interviews to answer these questions and our choice of literature is intended to put the process of change into a wider context. The answers show that the library was dissatisfied with the former system and have instead expressed a desire to shift the focus of their classification system to their users.
