Christofi, Marios (author)The process in which a smooth laminar flow transits to a chaotic to a chaotic, turbulent state, is a topic of particular interest in the sectors of energy technology and aerodynamics. To study the different paths that can be followed during the transition process, various tools and methods have been developed. A preliminary investigation of the...master thesis 2021

Colaco, Grevil (author)Nitrogen oxides (NOx) are significant sources of air pollution. Nitrogen oxides like Nitric oxide (NO) and Nitrogen dioxide (NO2) are mainly responsible for the acid rain and smog. Nitrous oxide (N2O), also known as the laughing gas, is the major greenhouse gas that is responsible for the ozone layer's damage in the...master thesis 2020

Jhamb, Shubham (author)The scientific community is consistently focused on identifying new sources of energy, which can reduce the consequences of climate change and depleting natural resources. Organic Rankine Cycle (ORC) based power systems have been touted as one of the promising technologies of extracting thermal energy from waste-heat and renewable sources such...master thesis 2020

de Goede, Roel (author)A study of five European estuaries by Winterwerp and Wang (2013) showed that tidal ranges increased significantly along with the ongoing narrowing and deepening of these estuaries. In addition to an increase in tidal range, a dramatic increase in suspended sediment concentrations has been observed in the Ems (Germany) and Loire (France)...master thesis 2020

Bouwman, Dennis (author)Using an idealized width-averaged model, the influence of spring-neap cycles on the transport and trapping of suspended fine sediment in tide-dominated estuaries is investigated. To this end we introduce a multiple time scale expansion. This provides a mathematically sound argument for treating the fast ebb-flood cycle and the slow spring-neap...master thesis 2019

Kosters, Anna (author)Like many rivers around the world, the Loire river in France has a history of human interventions in order to facilitate navigation and port development. Next to affecting bed levels directly, the heavy modification of the river-estuary has induced significant changes in the hydrodynamic and morphodynamic behaviour of the Loire. As a result, the...master thesis 2019

Dangal, Sagar (author)This paper investigates whether spring-foam technology in an aircraft seatpan can reduce weight and at the same time provides equal or better comfort. Firstly, through literature studies and iterative design process a prototype seatpan was designed and developed using spring-foam technology. This was then tested against standard aircraft seat...master thesis 2018

Stegeman, Judith (author)More families prefer living in the city, as the city has to offer social networks and facilities close by. Whereas before families left to the suburban areas, they now become city families. This development is attractive for the city, as city families offer liveliness and have a good influence on the economics. However, the city has no suitable...master thesis 2018

Carzana, Livio (author)When sunlight illuminates a body, a tiny pressure is exerted upon its surface due to the photons impacting on it. Such a principle forms the basis of solar sailing, in which the solar radiation pressure is used to accelerate highly reflective lightweight structures called solar sails. Similarly, a laser-enhanced solar sail is a solar sail in...master thesis 2017

Nederstigt, Pim (author)A generalized isentropic gas model is derived following earlier work by Kouremenos et al. in the 1980s, by replacing the traditional adiabatic exponent γ by the real exponents γPv, γTv, and γPT, describing the isentropic pressure-volume, temperature-volume, and pressure-temperature relations respectively. The real adiabatic exponents are...master thesis 2017

Iyer, S.V. (author)In recent years, the scientific community has shown increased interest in the use of uncertainty quantification techniques for complex thermodynamic systems. One such complex system is the Organic Rankine Cycle (ORC) power system for which a turbine is often the prime mover. These systems operate in a region close to the critical conditions of...master thesis 2015

Van Dijk, X.G.P. (author)The project is the result of a combination of operations performed on the site adjacent to Fatih mosque. It aims to programmatically complete the area’s nucleus to adequately provide for a pluralistic society in conjunction with Fatih mosque that currently dominates the area with its singular religious program. The essential objective is to...master thesis 2014

Bos, G.A. (author)This thesis represents a graduation project that was done for the early stage startup: Spaac. The alternative title is: A Design Intervention to Stimulate E-Bike Acceptance. A bicycle was designed to appeal to young commuters that currently do not ride e-bikes because of the social stigma. The Cultural Strategy of Douglas Holt was used to come...master thesis 2013

Bade, J.J. (author)This graduation project provides an answer to the question: “What user experience should be offered to the participants at what moment in the entire suborbital spaceflight experience?” by defining ‘a moment’ and designing the experience that should be offered at that moment. Abstract Despite the rapid development in the suborbital spaceflight...master thesis 2010
