Sizing Optimization of a Hybrid Propulsion powertrain for a Crew Transfer Vessel incorporating uncertainties: towards a cost-effective, eco-friendly design

A major transition became necessary for the maritime industry to meet the IMO’s targets for mitigating the carbon footprint of the sector by at least 50% by 2050. One of the promising methods to lower the emissions is the ship's hybridization. An enormous increase in pilot and demonstration projects for that purpose is being observed. This...

Vector field formation control: Fixed-wing formation control based on time-varying vector field

The mission control of a fixed-wings UAV is slightly more complex compared to other models like quad-rotors or unicycles since the dynamic of a fixed-wing aircraft does not allow rapid direction changes or stop-rotate-go type of movements. Those restriction needs to be taken into consideration when building a mission control system, moreover,...

Utilizing crosswise self-growing connection as load-bearing element in building design

Within the context of utilizing alternative materials to promote sustainable construction in the building industry, Living Architecture is a concept that uses living organisms as the building materials. As a rather unconventional approach, it possesses benefits such as low cost, not requiring considerable workforce or industrial material, carbon...

Living Trees as Structural Elements for Vertical Forest Engineering

The application of vertical forests in the building industry is a popular development with promising advantages regarding sustainability. However, placing trees along a façade gives additional loads which often results in extra material use. This is undesired concerning building design, costs, and the environment. To mitigate these adverse...

Visually grounded fine-grained speech representations learning

Visually grounded speech representation learning has shown to be useful in the field of speech representation learning. Studies of learning visually grounded speech embedding adopted speech-image cross-modal retrieval task to evaluate the models, since the cross-modal retrieval task allows to jointly learn both modalities and find their...

Active Gust Load Alleviation for Flexible Wing Aircraft

This paper presents a novel active gust load alleviation approach within a multi-objective flight control framework developed by NASA for a flexible wing aircraft. The aircraft model is based on the NASA Generic Transport Model (GTM). The wing structures incorporate an aerodynamic control surface known as the Variable Camber Continuous Trailing...

Design of an Energy Management System for usage in the ‘DISQ’ portable fitness device

In this thesis the design of a frictionless resistance system with a speed independent mechanical resistance is presented, this system is meant for the portable fitness device "DISQ". The goal of this device is to provide a mobile exercise similar to an exercise with weights but with more flexibility. The goal of the change from the current...

Improving robustness of pose estimation in AR using motion segmentation

Recent improvements in mobile technology have allowed computationally intensive augmented reality systems to become increasingly ubiquitous. As will be shown in this thesis an increasing number of companies have started developing markerless AR systems that can be used professionally. Robust pose estimation is essential for such systems to...
