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.

This thesis has been performed for the company System Andersson as a part of the bachelors degree in information technology at the School of Engineering in Jönköping. The thesis is based on the development of an iPhone application.System Andersson has an application for Android that is being used for their MPS system (material and production control system). Their customers, however, have also showed interest in being able to use this application for iPhone.The students handle the subject of iOS developing, including the design of the application, the use of the development language Objective-C, the use of the scripting language of Json used for server connections and SQL.The primary goal with this thesis has been to improve the students knowledge in such subjects as application development for mobile platforms, in such areas as Xcode, which is the development platform that Apple uses and Objective-C, which is the development language being used. The result of this thesis is an almost fully functional iOS application, similar to the Android application with some functionality missing..

This bachelor thesis aims to analyse the effects of changes in management control systems following acquisitions, and deduce whether or not these effects are in line with the acquiring firm's objectives of the acquisition. Through a case study of technician consultant firm Energo, acquired in 2010 by ÅF, the study assumes the perspective of the acquired firm. Data has been collected through in-depth interviews at Energo and ÅF and complemented by internal documents to enrich and validate specific facts and statements. Data was then arranged and analysed through Otley and Fierriera's (2009) framework Performance Management Systems to understand how management control systems were constituted before the acquisition, what changes were made following the acquisition, how this process was accomplished and how it was experienced, in order to come to conclusions about the effects of these changes. The study concludes that the changes in Energo's management control system following the integration with ÅF, had significant effects on the outcome of the acquisition, primarily as it led to a high rate of Energo's employees resigning.

Protected Designation of Origin (PDO) is a quality control system created by the European Union (EU) to protect integrity of certain food and drinks that are produced in a specific area in a unique way. By protecting these products, the EU can certify that the traditional region-specific methods of food and drink production are preserved. The EU countries that follow such a system are mostly from Southern Europe. For instance in France, the PDO system has helped improve the income for farmers, boosted the rural development and assured protection for farmers against the abuse of their brand and the selling of their products by outsiders. In Sweden, there are no PDO products yet, instead there is Protected Geographical Indication (PGI) and Traditional Speciality Guarantee (TSG) that are not as protective as PDO.

Our purpose with this qualitative study is to investigate how teachers experience their work situation, using Karasek and Theorell?s demand-, control- and support model. The study is based upon ten semi-structured interviews with gymnasium teachers. The interviews were transcribed and coded with three different themes; demand, control and support. We analyzed the results with Karasek and Theorell?s mentioned model.

Målet med det här arbetet var att skapa en konceptuell designprototyp för en scenarioeditor åt en digital version av utbildningsverktyget Emergo Train System. Rapporten ämnar ta upp och presentera den arbetsprocess som lett fram till designprototypen och dess utvärdering. I rapporten tillkommer även en diskussion kring hur en scenarioeditor bör utformas för att stödja skapandet av ETS-scenarion samt hur ett flexibelt arbetssätt stöds i form av skapandet av scenariorepresentationer.Intervjuer genomfördes med instruktörer och systemansvarige för ETS, samt observationer av iordningställande av ett ETS-scenario. Datainsamlingen analyserades och resulterade i en kravspecifikation för den digitala scenarioeditorn. Den prototyp som utformades gjordes så i pappersformat och utvärderades tillsammans med personal från Katastrofmedicinskt centrum i Linköping. .

Ecolean Development AB are developing and manufacturing filling machines for pasteurized liquid food products. Because of lack of any appropriate supplier of box closer which seals boxes with small flaps, they have decided to start a project to develop a prototype of a box closer. Due to long experience from industrial automation I have been given a chance to develop control system for a box closer. Degree thesis involves electric design in ELPROCAD ic PRO and programming of PLC (programmable logic controller) and HMI (Human Machine Interface). The report describes degree project from the project plan phase via the development phase to the conclusions.

The main purpose of this thesis is to examine what problems may arise when converting class symbols from one classification scheme to another. In order to fulfill this purpose, a conversion table between parts of the Swedish online-version of the UDC and the Swedish classification system SAB was constructed. For main classes 0 and 3 every class number from this abridged version of the UDC was converted, whereas for the rest of the main classes only class numbers with fewer than four figures were converted. The conversion table was constructed using the alphabetical index of SAB and different UDC-indexed library catalogues. Various aspects of the conversion table were then analysed using methods mainly devised by the authors themselves, but inspired by lexicography and multilingual thesaurus construction.

This thesis has been done at the Unversity of Örebro for Örebro University Hospital (USÖ). In our work we have developed a product for hearing tests to determine hearing thresholds of small children. Our product contains software and a control surface for controlling two separate screens. One of the demands was that our software could handle big file libraries. Reliability and simplicity were essential for the user.In our work we have utilized programming of both microcontrollers and Windows software.

Because of new emission and on board diagnostics legislations, heavy truck manufacturers are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania's next generation EGR system consisting of a poppet valve and a two stage cooler. The model will be used to extend an existing mean value engine model.

This master thesis is a part of the DySCAS project at ENEA. The purpose of this thesisproject is to add support for streaming media and USB support to the DySCAS demonstratorplatform.To achieve this, some of the widely used middlewares available today were studied. The onethat proved to be of most interest is CORBA. Although CORBA?s solution to streamingmedia couldn?t be used due to their use of object programming, the CORBA solution didprovide some interesting thoughts regarding how the USB devices should be handled, in thiscase their ?resource inspector? and ?trading service?.Ethernet was the chosen network to support streaming media.

The company Sound Precision has developed a new Line Array loudspeaker system (VHA-40). When using this system, their customers need computer aid to get the best possible sound-quality and control of sound levels for the whole audience. The aim of this thesis is to develop a truly useful sound quality simulator for the VHA-40. The system will help the sound engineers to position the loudspeakers for optimal sound by simulating loudspeaker configurations and visualizing the resulting sound quality and quantity. To solve this a human-centered design (HCD) approach is taken to implement a system that is truly useful for the users, meaning that they will use it more and hence deliver better sound for the audience.

This master thesis reviews advances in detection and diagnosis of static friction (stiction) in control valves. Control valves suffering from stiction results in oscillating control loops which in turn decreases both the process stability and reliability. Perstorp AB sees a necessity to automatically detect stiction in valves before the effects of the malfunctioning valves have become too severe. This thesis presents an introduction to maintenance, control loops and how stiction in valves can affect performance of control loops.A selection of methods presented in the literature are introduced and examined using normal operating data from the site in Perstorp. Common for all selected methods is their intuitive ideas and that they are based on normal operating data and minimum amount of process knowledge.

The purpose of this scientific essay is to evaluate if a continuous glucose monitoring system is something that can benefit Swedish animal health care. The study investigates if it is medically possible to use continuous glucose monitoring systems on dogs with an apparatus attached to their bodies. Furthermore, I try to establish whether this is possible in practice and how it could be done. The keywords used were diabetes mellitus, insulin, continuous glucose monitoring, blood glucose monitoring, dog, pet owner and animal nursing care. Furthermore, I wanted to find out if this system could be an alternative to currently established methods to measure the patient?s blood glucose level.
