This thesis work contains a litterature study about electrical motors in general and how PWM-patterns for brushless DC-motors can be made. A suitable method has been implemented as a simulation model in VHDL. A simulation model of a brushless DC-motor which describes the phasecurrents, torque and angular velocity has also been made. The motor model made simulations easier for the complete PWM-system. The design was synthesised and tested with a prototypeboard including a SPARTAN II FPGA.

Background: Low back pain (LBP) is a common disorder in the western world. A majority of those afflicted by a first acute episode is at high risk of developing sub-acute or persistent symptoms. Persistent LBP can be caused by pathological changes in the discs and disturbed neuromuscular activation, which can cause hypotrophy of the extensors strong type-2 muscle fibres. Deadlift (DL) is an exercise that may correct all these pathological transformations. Aim: To investigate the effect of DL-training on patients with persistent LBP.

This two years master's thesis examines the experience of children who read to a dog. The theoretical framework is inspired by sociocultural theory developed by Roger Säljö and the concept carnival inspired by Mikhail Bakhtin. The sociocultural theory has been chosen because it emphasizes the role of practice, instruments and communication in learning and the concept carnival has been chosen to analyze the experience of reading to a dog.The method used is qualitative interview and observation. A total of eight interviews and two observations when children read to a dog have been collected. One interview is with a teacher and seven interviews are with the children (six children participated and one child was interviewed twice).

In search of a stage language that resonates in historical disciplines, I have explored the possibility to expand my performing arts through the language of Indian classical Odissi, through different forms of storytelling. In my work I have focused primarily on two projects inspired by the original scripts of Macbeth by William Shakespeare and Breaking Bad by Vince Gilligan. I have outlined examples of methods and techniques used in the process.The work also shows how Odissi has evolved from a religious and philosophical tradition of temple dance; into modern stage theatre performance.The work aims to connect Odissi with western performing art. In this process I have been using my own knowledge about Odissi as a tool in combining both the traditions, a fusion in action.I will physically examine the artistic idiom, the characteristics, the actions and deeds found in stylized Odissi imagery and symbols, traditionally used to embody mythological and epic stories. A rendezvous between East and West.

Color management has become more common now than ever in the graphic trade. Calibration andcharcterization are words that are mentioned very often when it comes to controlling colors andwhen you want a printed picture to look the same as an original photograph. The problem is thatthere are not so many people that has the knowlegde about this subject. Even if a printer supportscolor management it is not sure that the result is going to be satisfied and that a printed picture isgoing to look the same as the original.The printers which were used were Hp DeskJet 970 Cxi, Xerox Docu Color 12 and AgfaChromapress 50i. The theory of color, colour management and the equipment which were usedare described in the first stage.

Title: Multi channel publishing: a qualitative study on how Norrköpings Tidningen publishes news in multiple channelsAuthor: Roland AlbinssonThesis supervisor: Per-Anders ForstorpBackground: In this day and age, the media is omnipresent and a part of our daily life. The phenomenon of media convergence can be traced back to the birth of the internet, and today all of the major newspapers have a website of their own. As a result of multichannel publishing, consumers have a wide range of tv channels to choose from, but there is still uncertainty as to whether more channels automatically equates to more and better news. There is no doubt about the fact that multi channel publishing is a necessary survival skill for media conglomerates today, but effects such as news recycling and the concentration of ownership are in conflict with the consumers? availability demands.Purpose: The purpose of this thesis is to, by means of a case study, describe how NT?s multi channel publishing is an expression of media convergence, as well as to study how the news are affected by multi channel publishing.Research procedure: This study is based on three different research methods, observations, text analyses and qualitative interviews.

This thesis investigates the communicative role of scenography in the performing arts for children, with an aim to make the readers understand the ways in which a set design can be optimized so that a young audience can be able to interpret the play and its message.The art of scenography is complex and includes many elements. The research questions can therefore be grouped into three clusters: one artistic oriented (How does the scenographic process work and what is its relation to the scenic piece at large? In which ways may scenography be used to support the desiderate interpretation?), one audience oriented (Which work processes enhances the chances of creating dramatic art that is perceived as meaningful to the audience? On what premises can the semiotics of theatre be used in the performing arts for a young audience?) and last a cluster that focuses on Den magiska cirkeln (The Magic Circle) by ung scen/öst (What is told in the show and how is this portrayed in the scenography? Who is in the target group, and does the audience get the feeling of the performance as intended?).Den magiska cirkeln is used as a case study in the thesis in order to reflect the theoretical material. Methods in the case study includes performance analysis, a survey completed by 178 people in the audience and an interview with scenographer Anna Dolata. 14 performing analyzes of Swedish children?s theatre shows have been made in addition to the case study.The thesis analyses and compares two work logics; the internal logic and the external logic, and it is shown that meaningful interpretations are likelier to happen with an external logical point of view.

Background: War-related amputations are represented by a unique group of patients because of the wounds complexity and scope of several serious injuries. To prevent and avoid care suffering and suffering of the patient, this study focused on the nurse's way to manage and identify the needs of this unique group of patients who have suffered from war-related limb loss. To undergo a traumatic amputation is a big change for the victim, and the nurse has an important role in responding to the patient and their needs Aim: To illuminate nursing care of patients with war-related limb loss. Method: The chosen method was a literature review. The data consisted of nine qualitative and three quantitative studies.

Growth models are very useful tools for forestry to predict growth and yield. With growth models and optimising tools you can manage forest stands in a way that maximize benefit and income. There are three major types of growth models. Stand models; stage structured models and single-tree models. The most advanced models give the most accurate forecasts.

The main focus of this study was to investigate how Swedish military veterans experience that events during an international service affect them after completed mission. This also includes the contact with their relatives. Secondly, this study deals with the course of the crisis, personal defense mechanisms, cumulative stress and post-traumatic stress syndrome (PTSD).The study was performed using a qualitative method and comprises individual interviews with six Swedish veterans. The responders were all men of different military positions, who participated in one or more international missions during 1993 to 2011.The results of this study show that, according to the veterans, the return back home is the most strenuous part of an international mission. With all the new experiences that an international service brings fresh in their memories, it is hard to re-adjust to the life of a civilian.In connection with the return back home, different degrees of stress reactions were also commonly seen, for example sleep disturbance, restlessness and exhaustion.

AbstractThe aim in this dissertation is to investigate into the working of the rehabilitation process as to actors involved. A specific focus has been set on the component ?Work introduction?. The study shows that the road back to work is a complex matter. Individuals involved have different backgrounds and living situations, which influence this rehabilitation.

Syftet med den här uppsatsen är att studera vad som har påverkat spotpriset på el i Sverige mellan åren 1996 och 2002. För att besvara syftet har de variabler som påverkar utbudet respektive efterfrågan, och därmed också spotpriset på el, identifierats med hjälp av traditionell ekonomisk teori. Därefter har en modell utformats och lösts med hjälp av Two-Stage Least Square metoden. De inkluderade variablerna i modellen är disponibel inkomst, pris på olja, teknologisk utveckling, kapacitet samt importerad kvantitet el. Förklaringsgraden på regressionen blev cirka 82 procent vilket tyder på att det kan finnas variabler som påverkar spotpriset på el som utelämnats från modellen.

Denna rapport innehåller de samlade erfarenheterna från ett produktutvecklingsprojekt i kursen TDDD77 vid Linköpings universitet. Projektets mål var att skapa en applikation för att visualisera mätdata från en specialutrustad bil på en surfplatta. Detta var önskvärt då det inte fanns något sätt att se om någon sensor slutade fungera mitt i ett test. Projektet delades upp i en förstudie följd av tre iterationer, där en färdig produkt presenterades på en teknisk mässa i slutet av iteration 3.Resultaten visar att Essence Kernel Alpha States kunde användas som en hälsokontroll för projektet, men då de kunde ses som rätt vaga och lämnade rum för tolkning passade det bäst som ett komplement till exempelvis milstolpar.Att använda Google Protocol Buffers sågs som ett viktigt tekniskt val tillsammans med uppdelningen av klienten i front- och back-end. Protobuf underlättade kommunikationen mellan server och klient som annars krävt ett nyskapat protokoll.Uppdelningen av front- och back-end underlättade inte bara resursfördelningen vid utveckling utan även vid felsökning då det i många fall blev lättare att se precis var felet uppkom.
