Interactive Visualization of Statistical Data using Multidimensional Scaling Techniques
This study has been carried out in cooperation with Unilever and partly with the EC founded project, Smartdoc IST-2000-28137. In areas of statistics and image processing, both the amount of data and the dimensions are increasing rapidly and an interactive visualization tool that lets the user perform real-time analysis can save valuable time. Real-time cropping and drill-down considerably facilitate the analysis process and yield more accurate decisions. In the Smartdoc project, there has been a request for a component used for smart filtering in multidimensional data sets. As the Smartdoc project aims to develop smart, interactive components to be used on low-end systems, the implementation of the self-organizing map algorithm proposes which dimensions to visualize.
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.
SMART board i undervisningen. Lärares arbete, elevers möjligheter...?
Syfte: Syftet med studien är att undersöka hur SMART Board användas som ett pedagogiskt redskap i undervisningen inom årskurs 1 till 5. Detta med utgångspunkt i ett specialpedagogiskt perspektiv, där SMART Board sätts i relation till möjligheten att vara ett verktyg, samt del av ett förebyggande arbete, som eventuellt kan underlätta inlärning och/eller skolgång för elever som kan möta olika svårigheter i skolmiljön.Teori: Teorianknytningen i studien utgår ifrån det sociokulturella perspektivet.Det sociokulturella perspektivet grundas i att sociala konstruktioner påverkar den verklighet vi lever i och uppfattar, samt att kunskap är en konstruerad representation av verkligheten. Studien anknyter även till det specialpedagogiska forskningsområdet där det är studier omkring det preventiva arbetet som står som forskningsobjekt.Metod: Undersökningen utgår ifrån en kvalitativ studie där observation och intervju används som metod för att förstå människors beskrivningar och uppfattningar. Observationsstudien är en minietnografiskt inspirerad studie och intervjustudien utgår ifrån den kvalitativa forskningsintervjun. Resultatet bearbetas och beskrivs utifrån en tolkande ansats.Resultat:Resultatet från undersökningen påvisar att SMART Board kan vara ett pedagogiskt redskap, som kan underlätta inlärningen för elever.
Implementation av Microsoft Exchange ActiveSync mot en molntjänst
This report describes a bachelor thesis work performed at the cloud storage company CloudMe in Linköping, Sweden. The storage service provided by CloudMe allows users to access their files seamlessly from multiple units at the same time. In the cloud there is storage provided for contacts, calendar and e-mail, which is data nowadays normally used by smart phones.Exchange ActiveSync is a protocol developed by Microsoft which, among much more, provides functionality to synchronize the previously described data. This protocol is supported by the smart phone developers and the ability to synchronize over the exchange protocol is implemented in products by default. Due to this fact it would be preferable to implement support for synchronization from CloudMe to phones over this protocol.
Utvärdering av Smart Cable för att se belastning på bergbultar
Syftet med detta examensarbete är att studera om SMART Cable Bolt kan användas som en mätmetod och som en del i utvärderingen av det förstärkningssystem som LKAB använder sig av i dagsläget. I och med att man tar ut berg när man bryter malmen så ändras spänningsförhållandena och stabilitetsproblem kan uppstå då spänningarna överskrider bergmassans hållfasthet. LKAB:s gruva i Malmberget består av ett tjugotal malmkroppar varav man idag bedriver brytning i hälften. Stabilitetsproblemen varierar i storlek och omfattning mellan de olika malmkropparna. I Alliansens malmkropp, som är i fokus för detta examensarbete, är det framför allt i de längsgående orterna som problemen uppkommer.
En kvalitativ undersökning om användandet av datorer, IKT och SMART Board i undervisningen
This report is an analysis of the gender representation in Swedish sports media, a comparison between sport in public service television for adults and children. The study explores the differences between the number of male and female sports in the matter of air time and also the number of male and female appearances in the TV shows. The programs studied in this report are the Swedish SVT?s Sportspegeln and Lilla sportspegeln. When we began this analysis we were under the impression that men would be over-represented, but that representation in sports television for children would be more gender equal than the adult counterpart. The result of the analysis confirmed previous studies stating that men dominate the sports programs in Swedish public service television.

This report is written for a consultant networking company with the purpose to review the development ofthe company's remote connections from a user friendly and security perspective.This includes an investigation of the possibilities to consolidate existing authentication methods foraccessing customers. The problem lies in the amount of methods being used. Through case study wefound that smart cards, SMS-service, software and hardware tokens exist.The only method feasible from a security perspective is smart cards. Since the method is not commonlyused by the company's customers a standardization of it would be counterproductive.Also, the purpose of this report is to investigate how the ongoing internal development of the remoteconnection will affect the company's clients. Within this framework we have also verified a designsuggestion.We interpret, after the completion of the case study, that the internal development of the remoteconnection is marginally affected by legal perspectives.
Traditionell ekonomistyrning vs modern verksamhetsstyrning - en fallstudie av ett växande företagsstyrfilosofi
The purpose with this paper is that trough a description of the management
control at Jitech AB find out if traditional management control have been
abandoned for benefit for modern management control and in which extent the
transition have happened. Further is the second purpose with this paper to find
out which decisions that lies behind the design of the management control and
how these are in opposition to with the theory..
Missilstyrning med Model Predictive Control
This thesis has been conducted at Saab Bofors Dynamics AB. The purpose was to investigate if a non-linear missile model could be stabilized when the optimal control signal is computed considering constraints on the control input. This is particularly interesting because the missile is controlled with rudders that have physical bounds. This strategy is called Model Predictive Control. Simulations are conducted to compare this strategy with others; firstly simulations with step responses and secondly simulations when the missile is supposed to hit a moving target.
Office Smart Client för dokumentsökning i Platina
Datoranvändare nyttjar idag Internet i sitt dagliga arbete, webbapplikationer är vanligt förekommande vid detta arbete. Prestanda hos webbapplikationer (thin clients) är dock av många orsaker väldigt begränsad jämfört med rich clients, detta tillsammans med övriga begränsningar hos thin clients har medfört att en klienttyp som sammanfogar fördelarna hos rich clients med fördelarna hos thin clients blivit allt mer efterfrågad. Smart Clients bygger på en fusion mellan rich clients och thin clients, Smart Clients är ett relativt nytt koncept som utvecklats av Microsoft med utgångspunkten att klienter ska vara lätta att administrera och uppdatera. Samtidigt ska möjligheten att använda lokala resurser både i form av mjukvara och hårdvara finnas, för att effektivt hantera den beräkning, visualisering och lagring som klienten nyttjar. Slutligen bör en Smart Client dra nytta av funktionalitet hos servers för att ge användaren tillgång till aktuell information.
EKONOMISTYRNING AV BUTIKSVERKSAMHET: ? en fallstudie av modeföretaget ?Alfa?
The aim of this thesis is to examine how salesperson control can be exercised in a retail store environment. A case study has been performed on a Swedish fashion company emphasizing the relationship between the company?s upper level management and their retail store operations in order to describe, analyze and classify the prevailing management control mechanisms. The paper presents an agency theoretical approach to the relationship applying behavior- and outcome based control theory, performance measurement theory and incentives theory in order to give a comprehensive image of the control system. The main finding is that the company?s management control system as applied to the sales force in its retail stores can be categorized as mainly behavior-based despite several explicit outcome-based features..

Analys och modellering av ljusbåglängdsregleringen i pulsad MIG/MAG-svetsning
This master thesis deals with problems in the arc length control in Pulsed MIG/MAG Welding. The main problem is that it is not possible to measure the arc length. In the present solution the voltage over both the electrode and the arc represents the arc length. To improve the arc length control a model of the electrode melting has been built. One output from the model is the voltage over the electrode and with this voltage together with the measured voltage it is possible to calculate the voltage over just the arc.

Integrering av Digitala Färdskrivare och Telematik för den nya Europeiska Standarden
This Master of Science thesis project handles issues around managing data from the digital tachographsystem. European legislation states that companies must download the data of the digital tachograph systemand store it for at least one year for control purposes. The system stores data on the vehicle unit located inthe driving compartment and on smart cards personal for each driver.Acquiring data from the previous analogue tachograph was done instantaneously since the data wasphysically printed to a circular paper chart when driving. To acquire data from the digital system one mustperform a download from the vehicle unit and later transfer it to some form of backup solution for longterm storage. Data must also be downloaded from the driver smart cards.Download of data from the vehicle unit is the most time consuming task and may take up to 30minutes pervehicle.
