Prestanda och precision pa? en enkortsdator i ett system med realtidskrav

The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

Europaparlamentsval och valdeltagande : En kvantitativ analys av förutsättningar för valdeltagandet

This study examines whether the policy breadth and the alternatives in European politics affect variations in voter turnout between member states in elections to the European Union Parliament.The theoretical approach assumes that; a larger political polarization, an increase in EU-skeptical parties and a greater voting mobilization among groups with less means results in higher voter turnout figures. The study also consider four other variables; whether the election is held on weekends or weekdays, whether elections coincide with other national elections, whether a country has held the presidential of the EU during or the immediate term prior to the election and finally the turnout figures from national elections.The research design is based upon a quantitative analysis using data from EP elections, national elections and databases from the European Elections Studies (EES). Study unit is twelve member-state countries and their four latest EP elections (1994, 1999, 2004 and 2009). The selected member-states origin from the EU-15 excluding Belgium, Greece and Luxembourg due to their compulsory voting laws.The study found relationships between higher turnout figures in EP-elections and increase in EU-skeptical parties, greater mobilization among groups with less means, elections held on weekends, elections coinciding with other, national elections and an increase in voter figures in national elections..

Ett designprojekt med fokus på för tidigt födda barns emotionella behov i kuvös

Babies born prematurely are deprived of normal sensorimotor stimulation when placed in an artificial environment, the incubator. The aim of this project was to design a series of products that could promote the baby?s emotional and neurological development, and to facilitate parental bonding. The products designed in this project has a theoretical basis on the research available today on cognitive and emotional development in children born prematurely. They were developed in close cooperation with a group of parents and nurses in a neonatal intensive care unit.Presence is a product collection for developmental care, consisting of a mattress, a figure and a necklace. The mattress has vibration sensors that transfer the mother?s heart beat and speakers with recorded heartbeat and her voice.

Betygsättning i Idrott och hälsa 1 : Likvärdig bedömning utifrån lärarens perspektiv

SummaryPatients with burn injuries involving more than 20 percent of the total body surface area lose a lot of fluid and are in the risk of developing a severe hypovolemia. Fluid resuscitation is a corner stone in burn care and is important for preventingfurthercomplications. The most common resuscitation formula is the Parkland Formula. Hourly urine output is a measure used to evaluate if the fluid given is sufficient enough to maintain a sustainable tissue perfusion. Inhalation injury, abuse of alcohol and drugs are some of the factors that may increase the amountoffluid needed.

Investeringsbedömningstekniker i praktiken: En fallstudie om Divisionen

?One Direction is not a phase like any other fandom I've been in, they're like my life? : en analys av fandom som källa till helighet

The aim of this paper is to study whether the way directioners (One Direction fans) on Twitter express self-understandings denote fandom as a sacred experience. For this purpose, the data was analyzed in relation to Nicholas Jay Demerath III typology of the varieties of the sacred experience. The method used was discursive psychology. The data was analyzed by how the fans draw the line between ?us? and ?them?, when expressing their self-understandings and their position in relation to others. Five themes were identified: (1) positioning and demarcation for membership, (2) group identity, (3) conflict, (4) the norms for behavior, opinions and language and (5) the group?s role and function.

Utmattning av järnvägsbroar i armerad betong : Enligt eurokoder

Commissioned for this report is Ramboll, Bridge and Tunnel Unit in Stockholm. Theidea throughout the work has been to primarily help bridge designers compilingadvice and instructions on how fatigue verification for railway bridges in reinforcedconcrete shall be performed under the new rules, the Eurocodes.After the introduction of the Eurocodes in 2011 has major problems emerged amongdesigners around Sweden. In some areas, it differs in the calculation rules comparedwith rules from the Swedish Transport Administration and the National Board ofHousing, Building and Planning calculation. Fatigue verification is one area where thenew calculation rules are different from the past.A large part of the report has been to interpret and find the relevant information inthe Eurocodes concerning fatigue. When questions or doubts have surfaced, this hasbeen discussed with Elisabeth Helsing at the Swedish Transport Administration andbridge designers at Ramboll.The result is a report where the structure is organized in the way that the bridgedesigners can move from cover to cover and realize that fatigue verification in realityfollows the same order as the report's sections.

Car-Pi ? Analys och guidning för bra bilkörning

Syftet med detta examensarbete var att skapa ett serverprogram i en enkortsdator som arbetar i realtid för att kunna hjälpa människor att köra mer ekonomiskt och miljövänligt i deras vardag.Detta var ett av målen ställda av produktbeställaren Ziggy Creative Colony. Ett mer långsiktigt mål från beställaren är att datorn skall installeras i en bil och kopplas till bilens on-board diagnostic-II (OBD-II)-uttag. Datorn ska sedan, via OBD-II, kunna samla information som till exempel hastighet, acceleration och bränsleflöde från bilens engine control unit (ECU). Serverprogrammet ska bearbeta denna information som sedan kommuniceras och visualiseras till bilföraren via en native mobilapplikation.Serverprogrammet byggdes i en linuxbaserad dator: Raspberry Pi och döptes av oss till Car-Pi. Car-Pi designades enligt arkitekturmönstret Model-View-Controller (MVC) som gör det lätt att underhålla, vidare-utveckla och implementera programmet av produktägaren, Ziggy Creative Colony, i framtiden.

Frekvensreglering i det nordiska kraftsystemet

Svenska Kraftnät is (together with the other transmission system operators of the Nordic power system) responsible for keeping balance between the generated and demanded power in the Nordic power system. Spontaneous load variations and system disturbances, however, lead to power imbalance followed by frequency variations. The frequency deviations can be limited to an acceptable level by the spinning reserve, mainly by hydro power control. But there are also other system properties which have a great influence on the frequency and system stability. The frequency and voltage dependence of the loads have a direct influence on the power balance.
