Parabolic reflector for focusing of underwater acoustic waves
(Master thesis; Mastergradsoppgave, 2017-06-15)Kongsberg Maritime has produced a transponder placed on the seabed designed for receiving and transmitting sound waves from vessels and ROVs. The soundwaves contain data regarding depth and location, and can be transformed to energy thus increasing the transponder battery lifetime. The transponder can only receive a small amount of energy, since its receiving area is small. This project aims to ... -

Analysis and Optimization of Sandwich Panels. Final report.
(Master thesis; Mastergradsoppgave, 2017-06-15)"The first part of this project, are general about sandwich structures. A sandwich construction, consist of two plate outsides (facings) glued to a core in the middle. Sandwiches are used in construction that must have a low weight, but a high stiffness. This indicated racing cars, aeroplane, ship shelters. To understand a sandwich construction, the basis, is to understand the sandwich beam. The are ... -
First aid equipment for use in cold climate environment: stretcher
(Master thesis; Mastergradsoppgave, 2017-06-15)"There is a need for a stretcher, which can also function as a sledge, especially for rescue missions in arctic climate, as the extraction point may only be accessible by people by foot or on skies. Existing solutions have some flaws, and some are not specifically designed for arctic conditions. The task is to develop a multi-purpose stretcher, operable by two members of the rescue team. In ... -

Optimal routing and charging procedures for electric buses
(Master thesis; Mastergradsoppgave, 2016-04-06)The goal of the project is to use Ant Colony Optimization techniques with Genetic Algorithm to design and analyse routes and recharging schedules for electric buses. One system so-called “en route” charging was analysed where the bus applies a kind of pantograph at bus stops to recharge the bus batteries. This implies more frequent, but short recharging intervals. The program offers diff t variants ... -

Subsumption architecture applied to flight control using composite rotations
(Peer reviewed; Tidsskriftartikkel; Journal article, 2016-03-19)In this paper the subsumption theory is applied to flight control through composite rotations where multiple tasks can be defined as simple rotations. The tasks can then be arranged as a hierarchy, where the primary task is always fully pursued, and conflicting lower level tasks are removed by the primary rotation. The concept is applied to a group of uavs that move through an urban terrain while ... -
A Decoupled Approach for Flight Control
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016)A decoupling method for flight control is presented that greatly simplifies the controller design. By approximating the higher order derivatives of the angle of attack and sideslip, it enables a rotation controller and a speed controller to be derived independently of each other, and thus gives access to a vast number of controller solutions derived for general classes of rotational and translational ... -
