GRÖNYTEFAKTOR I ETT NYTT PERSPEKTIV - Går ekosystemtjänster att mäta med fjärranalys?
Due to an increased population in cities the need of densification of cities increases. This means that the amount of ecological elements in the city is at risk of decreasing. Ecological services contribute to the city?s climate by softening the negative impacts that densification of cities means. Thus increases the will and ambition in city planning in to preserve greenery.This is an interdisciplinary thesis within the subject of geography that studies Biotope Area Factor (BAF), a planning tool that is used in city planning with the purpose of compensating for lost ecological services associated with new housing estate.
Utveckling av OBD-II-gränssnitt för fjärrdiagnostik av fordon
This Master Thesis documents the development of an On Board Diagnosis (OBD-II) interface for remote diagnosis of vehicles. The Master Thesis is part of a project at the company Wayfinder Systems in Lund. The purpose of this thesis was to design a scantool that communicates with a vehicle through its OBD-II port using relevant standards. In order to make the OBD-II interface development easier, a car simulator was first built. Both the car simulator and the OBD-II interface were implemented using a linux computer running a C-program with serial communication with an external electrical interface.
Support Vector Machines for Classification applied to Facial Expression Analysis and Remote Sensing
The subject of this thesis is the application of Support Vector Machines on two totally different applications, facial expressions recognition and remote sensing.The basic idea of kernel algorithms is to transpose input data in a higher dimensional space, the feature space, in which linear operations on the data can be processed more easily. These operations in the feature space can be expressed in terms of input data thanks to the kernel functions. Support Vector Machines is a classifier using this kernel method by computing, in the feature space and on basis of examples of the different classes, hyperplanes that separate the classes. The hyperplanes in the feature space correspond to non linear surfaces in the input space.Concerning facial expressions, the aim is to train and test a classifier able to recognise, on basis of some pictures of faces, which emotion (among these six ones: anger, disgust, fear, joy, sad, and surprise) that is expressed by the person in the picture. In this application, each picture has to be seen has a point in an N-dimensional space where N is the number of pixels in the image.The second application is the detection of camouflage nets hidden in vegetation using a hyperspectral image taken by an aircraft.
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.
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..

Det kommer göras jämförelser mellan dessa lösningar när det gäller kostnad, säkerhet, hastighet och tillförlitlighet. Detta har gjorts med vetenskapliga artiklar och intervjuer men rapporten innefattar även en praktisk tillämpling i form av ett experiment..
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.
Automobike: en cykel med aktiv balans
During spring 2012, six students at the Royal Institute of Technology in Stockholm carried out agroup project in the field of mechatronics as part of the thesis for the bachelor degree. The resultwas a robot with active balancing and the purpose of this report is to describe the development,manufacturing and problems that arose during the project. The finished robot has two wheelsmounted in line with each other, like a bicycle. Measurement data from an accelerometer and agyroscope are used together in a complementary filter for determining the angle from the verticalplane. For balancing, a PID controller was used to control the rotation of a reaction wheel, whenaccelerating causes a straightening torque.
Verksamhetsstyrningens inverkan på målprioritering - En kvalitativ fallstudie av två vårdcentraler i Stockholms läns landsting.
This study aims to examine the effect management control systems have on which goals health centers prioritize. The management control systems of one privately owned and one publicly owned health center have been studied through a qualitative case study. Robert Simons (1995) framework with four levers of control (diagnostic control systems, interactive control systems, belief systems and boundary systems) has been used to structure the study. For both health centers we found a conflict of interest mainly between the diagnostic control system and the beliefs system, where the diagnostic control system is biased towards quantitative goals and the beliefs system is mainly biased towards qualitative goals. However, despite the unbalanced levers of control the studied health centers have been able to reach a well functioning compromise between quantitative and qualitative goals..
