This report discusses the possibility for wireless charging solutions for electric vessels, with a focus on offshore wind turbine service. Where the charging time is minimal and safety for crew is important. Different types of wireless technologies have been studied, where the Inductive power transfer (IPT) is shown to be the preferred technology. Inductive power transfer (IPT) grants a safe ...

This thesis will explore interaction between non-supervised machinelearning agents, with a focus on traffic situations. We intend to showthat self-interested agents can arrive at mutually beneficial strategiesaccording to general game theory, achieving pure or mixed Nash equi-libria, and that this has practical applications for unmanned vehicles.We will start by verifying against simple one stage ...

Maritime Robotics main intent of the thesis is to develop understanding of a small deployable camera platform capable of providing elevated situational awareness for a small USV using a tether. The thesis goes into the state-ofthe-art methods of usage and control of a tethered drone. The thesis goes into the building and operating of the QAV250 Pixhawk 4 mini drone and making a drone simulation ...

Automatiske parkeringsanlegg er en innovativ parkeringsløsning som løser plassutfordringene som følge av befolkningsvekst, sentralisering og fortetning, men medfører samtidig nye utfordringer med hensyn til brannsikkerheten. Der en parkeringsplass tidligere var forbeholdt én bil, kan det i denne typen parkeringsanlegg være stablet flere biler i høyden. For rednings- og slokkemannskaper medfører disse ...

Arbeidsproduktiviteten i bygg- og anleggsnæringen i Norge fortsetter med en negativ trend, samtidig som byggekostnadsindeksen for nybygg stiger. Næringsaktører identifiserer et betydelig forbedringspotensial i bransjen. Flere peker på standardisering og prefabrikasjon som en del av løsningen. Consto Nord har bred erfaring med bruk av prefabrikkerte ytterveggselementer, både ved innkjøp og egen ...

This report details the implementation of a meshless animation framework for blending surfaces. The framework is meshless in the sense that only the control points are handled on the CPU, and the surface evaluation is delegated to the GPU using the tessellation shader steps. The framework handles regular grids and some forms of irregular grids. Different ways of handling the evaluation of ...

This paper studies the maximum available power of a dissipative capacitive power transfer (CPT) system submerged in seawater. The CPT system's maximum power capability is driven using the network theory, precisely the conjugate-image approach. The equations of the maximum available load power and the system's corresponding efficiency are expressed as a function of the capacitive coupling parameters. ...

Crystallographic aspects of heterogeneous plastic flow during ductile tearing are assessed experimentally by combining in situ synchrotron laminography imaging of notched flat samples with a full-field measurement technique and numerical simulations with the crystal plasticity finite element method (CP-FEM). Advantage is taken of the plane strain condition in the region ahead of the notch root (i.e., ...

<p>The classical Fourier Analysis has been developed in an almost unbelievable way from the first fundamental discoveries by Fourier. Especially a number of wonderful results have been proved and new directions of such research has been developed e.g. concerning Wavelets Theory, Gabor Theory, Time-Frequency Analysis, Fast Fourier Transform, Abstract Harmonic Analysis, etc. One important reason for ...

Hydrogen used as an energy carrier can provide an important route to the decarbonization of energy supplies, but realizing this opportunity will require both significantly increased production and transportation capacity. One route to increased transportation capacity is the shipping of liquid hydrogen, but this requires an energy-intensive liquefaction step. Recent study work has shown that the ...
