3D AUV Collision Avoidance
(Master thesis, 2007)An underlying requirement for any Autonomous Underwater Vehicle (AUV) is to navigate through unknown or partly unknown environments while performing certain user specified tasks. The loss of an AUV due to collision is ... -
A Comparison of Observers for Estimation of the Bottomhole Pressure.
(Master thesis, 2009)New offshore oil recourses that are developed are more difficult to drill and increase the requirements to the technology in the offshore industry. A relatively new technology is Managed Pressure Drilling where a choke ... -
A robust Multi-Loop tuning Procedure based at Succsessive Semidefinite Programming, that achieves optimal Performance and Failure Tolerance
(Master thesis, 2008)The desired properties of a multi-loop PID tuning procedure is to find some parameters that makes the plant robust, meet some desired performance requirements and guarantee failure tolerance. A detailed literature survey ... -
Active Pendulation Damping of Payload on Offshore Vessels
(Master thesis, 2007)Ship-mounted boom cranes play an important role in the offshore cargo transport process. In recent years, there has been significant need to increase stability of the payload during the cargo transport process for both ... -
Adaptive Gripping Technology: Development of a gripper interface for SCHUNK Dextrous Hand
(Master thesis, 2010)The use of robotic grippers offers huge potential benefits in industrial settings. The more advanced a gripper is, the more uses it can have, thus offering large economic benefits. On the other hand, the more complex a ... -
Adaptive Observer for Bottomhole Pressure During Drilling
(Master thesis, 2007)To satisfy the increasing petroleum consumption on a world wide basis there is a need to find new resources. As mature fields are drained, reservoir pressure falls, which again leads to tight pressure margins. To reduce ... -
Advanced leak detection in oil and gas pipelines using a nonlinear observer and OLGA models
(Master thesis, 2007)An adaptive Luenberger-type observer with the purpose of locating and quantifying leakages is presented. The observer only needs measurements of velocity and temperature at the inlet and pressure at the outlet to function. ... -
Aksjemarked-modell som spontant (adaptivt) utvikler urolig/ustabil dynamikk
(Master thesis, 2010)Oppgaven tar utganspunkt i en modell av det ideelle aksjemarkedet, og utvider denne for å vise hvordan spekulativ investering kan oppstå spontant fra et ideelt marked. Modellen utvikles gradvis og implementeres i Simulink. ... -
Alarmhåndtering
(Master thesis, 2007)Denne masteroppgaven rapporten rede gjør for krav og prinsipper bak et velfungerende alarmsystem. I tillegg dokumenterer den praktiskarbeid og resultatet av evaluering til alarmer tilknyttet prekompressorsystemet på Troll ... -
Analyse av reguleringsstruktur for LNG-anlegg
(Master thesis, 2008)For å oppnå en mest mulig lønnsom drift av et LNG anlegg, er det ønskelig at den til enhver tid opererer nærmest mulig sine optimaliserte tilstander. Dette gjelder i nærvær av alle mulig forstyrrelser som kan kunne påvirke ... -
Analysis and Control of an Intervention AUV with Modified System Parameters
(Master thesis, 2008)This report deals with a fully actuated underwater vehicle equipped only with thrusters to produce control forces. The issue addressed is the case where the vehicle picks up an object which is to be transported to another ... -
Anode Milling with an Industrial Robot Manipulator
(Master thesis, 2010)Force control of robot manipulators will be needed in the future to fulfill the potential of automated solutions. For this to be possible, adequate control systems for this special purpose are required. This thesis proposes ... -
Automatic Blood Glucose Control in Diabetes
(Master thesis, 2009)In this thesis, a closed-loop control algorithm for regulating the blood glucose concentration in type 1 diabetic patients is developed. Two control criteria are imposed on the system, namely: -Avoidance of hypoglycemia. ... -
Automatic Inspection of Cage Integrity with Underwater Vehicle
(Master thesis, 2011)This thesis is a preliminary study for the initiative to develop an autonomous AUV foruse in aquaculture. A micro-ROV is used to test the concept of inspecting net integrityin sh cages by analyzing video feed from a video ... -
Automatisert boring: Drilltronics
(Master thesis, 2009)Det foregår mye forskning og utvikling innenfor automatisering og optimalisering av borebransjen. Borebransjen har vært, og er fremdeles, en meget konservativ bransje, men bransjen er på vei inn i et generasjonsskifte både ... -
Automatisert system for marin fiskeyngelproduksjon
(Master thesis, 2008)Stor etterspørsel etter hvitfisk på verdensmarkedet har ført til økt interesse for oppdrett av marine fiskearter. For å oppnå en storskala produksjon av marin fisk kreves det også en storskala produksjon av fiskeyngel av ... -
Automatisk gjenkjenning av rullebaneterskel i flyfoto.
(Master thesis, 2008)Ved innflyging og landing av fly under forhold med redusert sikt brukes instrumentlandingssystem for veiledning langs en ønsket innflygningsbane. For å verifisere at instrumentlandingssystemet er innenfor gitte krav er det ... -
Automatisk Trimix blandesystem
(Master thesis, 2008)I forbindelse med dypere dykking er det behov for annen pustegass enn vanlig luft. En gassblanding bestående av nitrogen, oksygen og helium, kalt trimix, benyttes. Vanlig måte å lage denne blandingen på er ved å fylle en ... -
