Transportation of oil and gas by the Sea characterizes challenges from a safety viewpoint. In this type of transportation, different sizes of special tankers carrying oil and gas. The marine transportation of these scarce natural riches is involved with risks and hazards, which may lead to many losses; for instance, wasting oil and gas, injuries of people, damaging ships and properties, and damaging environment. The main purpose of this thesis is to evaluate the risks, hazards, and accidents during transportation of oil and gas (mainly Crude Oil, liquefied petroleum gas, and Liquefied natural gas) by the Sea with concentrating on transport safety. Hence, a better understanding of these risks and hazards can contribute to decrease of addressed losses.This study is carried out on risks associated with maritime transportation of oil and gas starting with describing the general casual chain (dealing with causes, incidents, accidents and consequences/causalities), continuing with describing risk analysis techniques (including event tree analysis and fault tree analysis) and risk control measures/options, and finally implementing aforesaid investigations on real data from two areas; namely UK territorial waters and the Baltic Sea.In this study, the results of analyzing data from 1991 to 2010 in UK territorial waters revealed that collision and grounding were two most common accidents in terms of crude oil tankers, LPG and LNG carriers in which 44% of all accidents were equally divided between collision and grounding.

The purpose of this thesis has been to build a parameterized model of a prototype motor in the program Solidworks, to use in future optimization of aspects of effectiveness and weight. The result were two models. The first model were one minor part of the whole design in 2D, to be able to optimize and study the minor part with a faster loss simulation. The second model was the whole design in 3D. The whole model were done with the three programs Solidworks, Comsol and Matlab.

LabVIEW och en USB-kamera har använts som hjälp till att göra utvärderingar och tester av systemet.

Our examination project has been to develop today?s existing walking frames and make them more exiting and user friendly for tomorrow?s users.The use of a walking frame today makes it easier for a person with a movement difficulty in different extent. It makes it easier with their living condition and the user get a more movement easier life where they can take care of the daily chores without any help from the society or the family members.With our product we get a product that not only makes it easier for the user to get out and get forward. We help the user to get forward where they often would have difficulties to get forward. An example is where its more steeper parts where it could be more difficult to get up or down and even with more difficult foundation due to bad weather.

Vidare testas metoderna operativt i industriliknande miljö och dess fördelar respektive nackdelar belyses. Metoderna ställs mot varandra och jämförs gällande pris och prestanda.

Valmets own foundry in Karlstad has during a long period of time had problems being profitable. The goal today is to turn this around. Today there are three different productionlines; engine blocks, Yankeecylinders and components for the wind turbine industry. This master thesis has focused on examining if value stream mapping is a useful tool to use in a foundry, and therefore outside the typical manufacturing industry. The target has also been to evaluate if there is a possibility to improve the flow in the foundry and also the results.During the 20 weeks this work has been done at the foundry data has been collected and analyzed.

The purpose with my project is to evaluate how Recreational Leaders use the outdoor environment, how much they use it and why. My method was to assemble the surveys which were answered nationally by Recreational Leaders. During my project I have investigated Recreational Leaders view on the outdoor environment by reviewing a survey. Those who answered the survey find that the desire to use the outdoor environment exists; they think that the benefits of moving the teaching process outside are plenty. The children receive fresh air, they get to practise manual ability and gross motor functions, stay healthy and are able to use their imagination and creativity.

Detta arbete avslutar magisterutbildningen inom Industriell design vid Luleåtekniska universitet. Arbetet har utförts på uppdrag av Agency-9, utvecklareav Javabaserade 3D-motorer. De har tekniken för att producera dataspel avtoppklass men ingen grafisk formgivning och produktion, och är i stort behovav att få igång detta. För att visa upp funktionaliteten i deras 3D-motorAgent FX vill de även ta fram ett demo. Metoderna som använts under arbetet baseras på teorierna om systematiskproblembehandling som lärs ut vid Institutionen för arbetsvetenskap, LTU.

 Autonomous cars or robot cars havebeen on the agenda ever sinceHollywood started with their Sci-Figenre, maybe even before that. A lotof things have happened since then andnow the self-driving vehicle is notfar away. In this project, theAutonomous car with microcontrollerand ultrasonic sensors, we are lookingat a way of making a small, regular RCcar autonomous with relatively simplemeans and investigate how the bigcompanies does it to learn more aboutthe development of the autonomous carsand their technology.We used an Arduino Uno R3 supplementedwith an Arduino Motor Shield R3 as ourmicrocontroller board and three HCSR04ultrasonic sensors. By removingalmost all of the old parts of the RCcar,except the two DC motors, andreplacing them with these new parts wemanaged to make a vehicle that drovearound in a room without crashing intoanything. We could have used entirelydifferent sensors, or supplemented theexisting setup with other sensors tomake it even more accurate andobstacle avoiding.

The purpose of this project was to further develop and complete a quadcopter that had been built in an earlier course at KTH, so that it could be used for demonstration and education at the school. The quadcopter was at the beginning of the project completed when it came to hardware, and there was some software functionality implemented but no system for automatic stabilization. The main goal of the project was to implement such a system, and to combine it with the previous functionality to make the quadcopter operable and able to fly. To create a functioning and stable ground multiple basic software features has been implemented, and on top of that additional software to improve the safety, stability and functionality. The most important part is the control system that is responsible for converting sensor and control signals to suitable motor values.

Spel idag kräver en enorm mängd arbetstimmar för att skapas, därför behövs alltid sätt att spara tid och automatisera processer. Algoritmer för polygoniseringen av skalärfält, som Marching Cubes, har under de senaste åren blivit ett allt vanligare tillvägagångssätt för att automatiskt generera terräng. Scenkomplexiteten och kraven för visuell kvalitet i dagens spel ökar ständigt. Därmed kommer också kravet för prestandaeffektiva renderingsmetoder. Deferred rendering är en renderingsmetod som kan hantera scener med stora mängder ljuskällor och hög scenkomplexitet samtidigt.

Denna rapport behandlar utvecklingen av styrelektronik för att styra likströmsmotorerna i en mobil robot. Målet var att roboten skulle kunna styras trådlöst via Internet. Ett motorstyrkort har konstruerats. I elektroniken ingår bland annat en mikrokontroller, som programmerats för att reglera motorernas hastighet. Mikrokontrollern tar emot kommandon från en PC, och motorhastigheten regleras genom pulsviddsmodulering via en H- brygga.

 SAMMANFATTNINGVårt projektarbete har omfattat en totalrenovering av en 6-cylindrig Jaguar motor från 1968. Dennadel har varit det sekundära syftet i vårt projekt. Den primära uppgiften har varit att skriva enillustrerad manual.För att finna orsaken till våra problem började vi med att genomföra en rad tester på motorn. Våradeduktiva och induktiva antaganden om vad som var fel i motorn grundade sig på dessa tester.Våra logiska slutsatser har dragits ur teoretiska resonemang och rent praktiska undersökningarav motorns inre delar och funktion. Det metodiska arbetet har begränsats till att på ett så logisktoch konsekvent sätt som möjligt lösa denna uppgift.

Vårt syfte med studien är att undersöka hur pedagoger arbetar med barnens motoriska utveckling i inomhusmiljön. Vi använder oss av kvalitativa intervjuer med pedagoger i förskolan och skolans förskoleklass till år tre. Det vi är intresserade av är pedagogernas tankar kring användandet av sin inomhusmiljö med avseende på den motoriska utvecklingen hos barnen samt för att se eventuella skillnader mellan verksamhetsfälten. Våra intervjufrågor behandlar fyra huvudområden, användandet av inomhusmiljön, vilka aktiviteter som genomförs, förhållandet till läroplanerna och motorikens betydelse. Resultatet visar att pedagogernas arbetssätt i förskolan och skolan skiljer sig en del inom dessa ämnesområden.
