Sensorer och system i mjölkkobesättningar : en litteraturstudie
The trend in milk production is similar in Sweden and across the world; the farms are getting fewer but increasingly bigger. The costs for hiring workers are increasing, which results in more cows per animal keeper. Sensors can then be a great tool for keeping track of animals which need special attention. With a reported decreasing fertility, sensors that can detect oestrus even at low levels can be especially helpful in bigger herds to pinpoint the cows that may be in oestrus. The number of farms with dairy cows that install AMS, Automatic Milking Systems, are increasing, and that also increases the need for sensors to control milk quality and composition when there is no visual control of the milk by a milker before milking starts.For the sensor data to be useful you have to have software designed to analyze and interpret the data to get relevant information that the farmer can use.
Adaptiv katalysatormodell för reglering
This master?s thesis describes the development of a model of the catalystsystem aiming at control by an MPC. A well functioning model, which is suitable in control purpose, is important while emission legislation become more and more hard to fulfill for the car manufacturers. Much research has been done in the field of physical modeling of the system, but in this work a linear adaptive time discrete ARX-model is developed and validated.The systems tendency to change its dynamic during usage implies that the model must be adaptive. The developed model proved to be well functioning and shows promising conditions for the MPC design.
Styrreglage för hållbarhetsstyrning - En fallstudie av hur företags interna styrning aktiverar Levers of Control för att uppfylla hållbarhetskrav
The connection between management control systems for controlling sustainability and a firm's motivation for engaging in sustainability is not completely understood (Arjaliès & Mundy, 2013). The aim of this thesis is to develop a more profound understanding for management control in achieving sustainable companies. To do this, we raise the question: How and to what extent do companies use management control systems to achieve sustainability compliance Simons's Levers of Control (1995) are applied to this question in order to get a consistent and thorough insight of management control systems. Hence, a case study of ABB:s work to achieve material compliance in accordance with EU-regulation was conducted. The findings of the case study reveal that ABB uses the regulations as explicit goals and implement them in sustainability procedures.
UML som stöd vid småskalig utveckling av ett inbyggt system
This project aims at investigating if the use of UML as a support to small-scale development ofan embedded system is relevant. The investigation is conducted by using UML during the initialphase of the development ofTelfafill, a filling machine by the company ?Telfafill AB?. The aimof the development of Telfafill is to separate the user interface from the control unit. In additionto this main objective, Telfafill AB would like possible changes to, and additions of,functionality of the filling machine to be investigated.Within the boundaries of this project, the development of Telfafill reached a full requirementspecification of the proposed system, and contact was made with potential external developers.No prototype construction had been started when the project ended.
Den politiska webben : en webbometrisk studie av nya sociala rörelsers användande av webben som informationssystem
Syftet med denna uppsats är att undersöka nutida sociala rörelsers aktiviteter på World Wide Web och ta reda på om det finns något sammanhängande informationssystem för dessa rörelser där, hur det ser ut och hur viktigt det är som informationskälla. Inom ramen för denna undersökning företogs först en teoretisk genomgång av begreppet sociala rörelser för att definiera undersökningsobjektet. Därefter introducerades den webbometriska metod som sedan användes för att analysera ett antal svenska nutida sociala rörelsers webbplatser. I samband med presentationen av den webbometriska metoden diskuterades också diverse problem rörande material och materialinsamling samt tidigare forskning på området. De webbometriska analyserna visade att det finns kopplingar mellan webbsidor som gör att de kan ses som sammanhängande informationssystem.
Rekommendationssystem för interaktiva musiktjänster : en utredning av aktuella trender och attityder gentemot framtidens rekommendationssystem diskuterat ur forskar-, industri- & användarperspektiv
Parallel to new technological advancements, including the development of interactive recommender systems, digital music services on the Internet, such as Spotify, have in a short time span gradually replaced former physical media such as CDs and MP3-players and become pioneers on a market with an otherwise uncertain future. By subscribing to the service, users have access to a vast library of music and from any device with Internet access. In order to provide a satisfactory and useful musical experience, different ways of coping with the vastness is required - which is precisely what recommender systems are for. Improved filtering techniques and use of devices built in sensors, make way for new opportunities of more precise and contextually tailored suggestions for track selection, which in turn leads to potential privacy issues when using interactive music services. But where do we stand today? By compiling, exemplifying and discussing three different perspectives with relating to the development of interactive music recommender systems, the objective for this paper is to provide a for science, industry and user, objectively nuanced account of current potentials and expectations.
Belöningssystem i heterogena organisationer -I teori och praktik
The purpose of this master thesis is to, with the strategies of the organization and the preferences of the co-workers in mind, explore how reward systems can be designed in heterogeneous organizations. This is done by interviewing store managers and sales personnel in a heterogeneous organization. The frame of reference deals with theoretical approaches on reward systems and is divided in the following sections, individual or group based, differentiated or not differentiated rewards systems and goals, measurements and rewards. These sections are highlighted from the following aspects, equity, implementation possibilities and finally environment. The theoretical discussion ends in the conclusion that heterogeneous organizations should have several different reward systems, but not if a restructuring process is in progress or the system becomes too costly.
3D-visualisering av robotsimulering
Visualization is a rapidly growing area of computer graphics. Due to the very progressive development of computer technology and especially 3D-graphic boards yesterdays imagination of visualizations, today is a reality. At Saab Bofors Dynamics in Linköping missile systems are developed. Through the development, different subsystems are simulated before the manufacturing starts. The results of these simulations have to be visualized to get a meaning.
Kommunicerbara Informationssystem
Nowadays naval units are participating in international missions, where new and in many cases tougher conditions will affect their propulsion. This essay deals with some of the now developed nanostructure coatings and gives a presentation of how the coatings could function on some exposed parts of the naval powertrain. The essay investigates the possibility that the coatings can be used as a protective layer that will reduce or prevent wear on selected parts of the naval powertrains. As a basis for the essay, nanotechnology is described, as well as different reasons that wear occurs and application techniques for coatings The conclusion is that nanostructured coatings can be applied and provide a much better result on hardness and wear resistance as of naval powertrains compared to micro-structural coatings, both for manufacturing and renovation. The essay presents a few examples of the military utility of the nanostructure coatings as well as suggestions for further research..

System, stabilitet och makt - informationsdiskursen i Organizing Knowledge
TitleSystems, Stability and Power. The Discourse of Information in Organizing Knowledge.AbstractThe aim of this Master's thesis is to inquire into the consequences of an unequal distribution of power between information discourses in the field of knowledge organisation. A deconstruction of Jennifer Rowley's and John Farrows introductory textbook Organizing Knowledge from 2000 is related to the major discourses of information in LIS. Questions posed in this study are: What meaning is ascribed to information in the material studied? Which information discourses are given a dominant position? Which are excluded? and: How does this affect the construction of the library and information science student's identity, in relation to practices of knowledge organisation? The theoretical framework is provided by Ernesto Laclau's and Chantal Mouffe's theory of discourse and combined with techniques for text analysis originating from the work of Norman Fairclough.The analysis reveals a strong domination of a cognitive discourse of information that underlines the importance of information systems for the organisation of knowledge.
Systemtid eller vårdtid? : En arbetsplatsstudie i vårdens digitala arbetsmiljö
Swedish healthcare systems have endured harsh criticism from healthcare professionals because of their inability to understand healthcare processes. These systems have been identified as significant time consumers, and Swedish healthcare is therefore facing a major challenge to assure patient safety. The following paper is based on a workplace study, which aims to examine healthcare systems? impact on physicians? practices. Our findings show that physicians spend substantial amounts of time chasing information, rather than managing information and pursuing healthcare.
