A fleet of autonomous sailboat could change our perception of the planet. An autonomous sailboat could not only conduct environmental research but also perform month long operations through the energy efficient wind propulsion. This thesis is the work behind the development of an autonomous catamaran model sailboat. A new mathematical model is brought forward and implemented for simulations perfo

Detta arbete är en översiktlig utvärdering av de konsekvenser som en förtätning i villaområden i Malmö kan tänkas bära med sig. Ett villaområde utgör typiskt en exklusiv boendemiljö i staden, med ett begränsat utbud av boendeformer och en trög omflyttning på bostadsmarknaden. Försöken i arbetet belyser att villaområden generellt har kapacitet att hysa fler hushåll, bli mer inkluderande och fungeraThis report is an evaluation on a general scale, concerning the consequences of densifying single housing areas in Malmö. An area consisting of single homes typically makes out a priviliged living environment, with a uniform range of homes, regarding residential sizes and forms for tenure, and a slow turnover in the housing market. This report attempts to show that single housing areas in general

Föroreningssituationen i Skurups dagvattensystem Regn- och avrinnande vatten, så kallat dagvatten riskerar att förorena vattendrag, mark och grundvatten med dagens separerade avrinningssystem som oftast leder direkt till recipient utan behandling. Tungmetaller är några av dessa föroreningar som undersöktes i Skurups stads dagvattensystem. På alla undersökta platser kunde tungmetaller återfinnas meThis study investigate the pollution levels (heavy metals) in Skurups city’s storm watersystem. Rain and runoff water (storm water) can be polluted and pose an environmental problem because it rarely gets purified on the way to our waterways. To find the various outlets where storm water reaches waterways, Skurups urban storm water systems were mapped. The city’s different businesses inside indust

Using a six-legged-robot as a development platform this thesis aimed to have a fully autonomic robot capable of navigating and mapping previously unknown terrain in three dimensions. During the project both hardware and software upgrades have been made such as implementing another computer on the robot and enabling wireless communication via Wi-Fi. Experiments were performed on a test track that

Syftet med uppsatsen har varit att bättre förstå hur unga konsumenter hanterar konsumtions- och servicemisslyckanden genom att söka en fördjupad förståelse av hur val av deras hanteringsstrategier (coping strategies) kan tolkas. Frågeställning: Hur ser unga konsumenter på konsumtions- och servicemisslyckanden och hur beskriver dem de hanteringsstrategier de använder? Metod: Kvalitativt angreppssät

A driver model can be used to predict the vehicle velocity and the energy consumption. It can be modeled such that it benefits from historical data and can be further improved if a navigation system is available. A well implemented driver model is important since the car fleet seems to be more and more electrified. The role of the driver model would then be to increase the accuracy for when the dr

Integrated modular avionics (IMA) architecture is an emerging concept in the military aerospace industry after being successfully implemented in the commercial domain. The highly modular architecture allows multiple aviation applications to execute on the same hardware thanks to defined standards by Aeronautical Radio, Incorporated (ARINC). System architects are responsible for designing and takin

60 % OF YOUNG SWEDISH PEOPLE IN THE AGES 18-25 ARE WORRIED ABOUT NOT SUCCEEDING IN LIFE. 72 % FEEL THERE IS AN IDEAL. 89 % OF THE WOMEN ARE STRESSED ABOUT LIVING UP TO THE IDEAL, 66 % OF THE MEN. THIS PROJECT IS AN INVESTIGATION OF PERFORMANCE ANXIETY. We live in a society where performances are valued so high that we believe it defines who we are. And for some reason it is okay to talk about inj

Enligt den amerikanska forskaren Richard Florida är det idag kreativitet och initiativkraft som driver ekonomin och utvecklingen framåt. Det samhälle som lyckas bäst är det som bäst tar vara på befolkningens kreativa potential och som mest framgångsrikt lockar till sig kreativa individer. Genom att analysera vilket samband som finns mellan Skånes kommuners satsningar på kultur & fritid och fasThe study aims to see if there is an impact of culture & leisure on property prices. To determine if there is a correlation method of regression analysis is used. The analysis is applied on two models, which will be called: Kommunmodellen and Staffanstorpsmodellen. Kommunmodellen consists of variables that explain property prices at a municipal level such as number of citizens, taxes, employme

Independent inventors typically start to develop a solution to a problem they have personally experienced. They quickly move from realization of a problem to an iterative process of sketching, building and testing. During these activities, little interaction with customers and other stakeholders was found. The main reason for this at an early stage was that they did not want to risk patentability.

Under en period mellan 1700-talet till början av 1900-talet upptecknades en mängd folksånger och danslåtar i Östergötland, min hembygd. Syftet med detta arbete är att artikulera kunskap om en scenmusikalisk process som i sin tur haft som mål att synliggöra detta material: genom att välja ut, arrangera, programsätta och tillsammans med medmusiker framföra östgötska visor har jag i en processbeskrivDuring the 17th, 18th and 19th centuries, many folk songs and dances were collected in the Swedish county of Östergötland, which is my home county. The purpose of this investigation is to articulate knowledge about how this historical material can be communicated. Therefore, in this case study I describe and discuss my selection, arranging, rehearsing and performing some of these songs, and how I

This thesis compares the performance of the first-differenced maximum likelihood estimator (FDML) and the Blundell-Bond continuously-updating system GMM estimator of the autoregressive parameter in an AR(1) dynamic panel model without exogenous covariates, particularly focusing on the close-to-non-stationary case. This case is far from trivial, as a high degree of persistence is the norm rather th

In this thesis a Mesos framework is built to enable dynamic scaling of a collection of HTTP application programming interfaces (APIs) in response to a varying request workload. Several scaling algorithms ("policies") that run on top of this Mesos framework are designed and built. Furthermore, a performance evaluation framework is designed and built. The evaluation framework is used to ev

Syftet med den här studien är att få en ökad förståelse för hur en man respektive en kvinna beskriver sina ledaregenskaper och ledarstilar jämfört med vad de faktiskt gör i praktiken. För att besvara syftet har vi utgått från följande frågeställningar: hur överensstämmer en mans och en kvinnas beskrivningar om sina ledaregenskaper och ledarstilar med vad de gör i praktiken samt hur en man och en k

To maintain a high position accuracy in robots is essential in today’s industry. Because of different factors, as for example wear and tear, the robots may need to be recalibrated after a while to maintain their high precision. Today the calibration can be costly. The robot is often sent away to be calibrated and will therefore cause stoppages in production, and if the calibration is performed in-

This study explores the Open Access phenomenon from the perspective of the commercial scientific publishing industry. Open Access has been appropriated by commercial publishers, once sceptical opponents of the concept, as a means among others of distributing scholarly publications. The aim of this study is to highlight a possible explanation as to how this has come about by looking at the internal

The use of industrial robots in manufacturing often requires good calibration approaches and tools to obtain and maintain the desirable accuracy of the robot, for the robot to be able to execute a task in a satisfactory manner. For high-accuracy methods of calibration, it is necessary to first identify the robot’s stiffness parameters. This thesis will focus on a method that is based on a clamping

The recent shift towards energy-dense and nutrient-poor diets has led to an increase of diseases such as obesity, diabetes and cardio-vascular disease. Due to poverty, geographical remoteness and lack of cultivable land, Kiribati experiences a double burden of malnutrition with high levels of NCDs among adults, and undernourishment among children. Since mothers are generally responsible for choosi

Konkurrensen är hög på den alltmer homogeniserade retail-modebranschen vilket kräver att företagen differentierar sig gentemot sina konkurrenter. Företagen fokuserar ofta på att stärka sitt varumärke genom att försöka omvandla frontlinjepersonalen till fullgoda varumärkeambassadörer. Frontlinjepersonalen har det huvudsakliga ansvaret för kundens uppfattning av varumärket i servicemötet. Därför för
