Zegers, Samuel (author)In several experiments, enzymes have shown an in increase in diffusivity in the presence of their substrate. The enhancement in diffusivity ranged from as low as 28% for urease to 80% in the case of alkaline phosphatase. There are two main competing theories. One asserts that catalytically driven boosts propel the enzyme forward in ‘leaps’,...bachelor thesis 2022

Sharif, B. (author), van der Maas, A. (author), van de Wouw, N. (author), Heemels, W. P.M.H. (author)The filtered split-path nonlinear integrator (F-SPANI) is a generic nonlinear controller designed to improve the transient performance of linear (motion) systems in terms of overshoot. The main idea underlying F-SPANI is that the amplitude and phase of an integrator can be tuned using independent filters, resulting in more efficient use of...journal article 2022

Boogaart, Thomas (author)The past 70 years has shown an incredible growth in air transport. The increase in flights has resulted in an increased strain on the environment. Climate change is a fact. Designers have been working on improving the aircraft, and in particular, the engine efficiency. By improving the internal components through better materials, new design...master thesis 2021

Yuan, S. (author), Lv, Maolong (author), Baldi, S. (author), Zhang, Lixian (author)This article investigates the stability of continuous-time switched linear systems with dwell-time constraints. A fresh insight into this established problem is provided via novel stability conditions that require the solution to a family of differential Lyapunov equations and algebraic Lyapunov equations. The proposed analysis, which leads...journal article 2021

Al-Zubi, Kadhim (author)Quintic Duffing oscillator is considered. Amplitude-phase relations are derived using averaging theorem and perturbation methods. First The forced quintic system is studied. Stability regions are com-pared to the general case with quintic-qubic non-linearity. Numerical results show that Perturbationmethod and averaging are in agreement with each...bachelor thesis 2019

Bertoncini, Chiara (author)Three interest rate models are researched: Displaced Exponential-Vasicek, Hull-White one factor and Hull-White two factors with time-dependent volatility parameters. The motivation for this is two-fold: firstly, we would like to understand how the capital calculations would be impacted when yield curves are modelled under the three different...master thesis 2018

Swart, W. (author)The aim of this thesis is to investigate the use of a bifilar pendulum for determining the moments of inertia of the TU Delft solar boat and to quantitatively predict the estimates. In the first part, several methods are discussed which can be applied in deriving the equations of motion of the pendulum. A new method, Kane's method, will be...bachelor thesis 2016

Natella, M. (author)The present work thus develops a low-fidelity formulation to investigate the flight dynamic stability of a flexible wing structure. The model is verified against other studies found in the relevant literature, which show interesting trends in terms of how some of the design variables or flight conditions influence the stability of the structure.master thesis 2015

Mourillon, N.K.N. (author)The stability of any structure is an important aspect in civil engineering. The subject of this thesis is the stability of the quay structure at the Amazonehaven, port of Rotterdam. The reason for writing this report is to investigate the safety and stability of the quay structure, which was built in 1990, throughout its service lifetime while...master thesis 2015

Kazemi Kamyab, V. (author)Time-accurate simulations of the thermal interaction of flows and structures, also referred to as conjugate heat transfer (CHT), can be computationally expensive. Furthermore, given the multi-physics nature of many engineering problems, resolution of other coupled phenomena, in addition to CHT, may also be of interest. This thesis aimed at...doctoral thesis 2013

Quaglietta, E. (author), Corman, F. (author), Goverde, R.M.P. (author)In the last decade simulation models and optimization environments have been developed that are able to address the complexity of real-time railway dispatching. Nevertheless, actual implementations of these systems in practice are scarce. Essential for implementation of an advanced dispatching system is the trust of traffic controllers into a...conference paper 2013

Gu, Y. (author), Prasad, R.V. (author), Niemegeers, I.G.M.M. (author)A Personal Network (PN) is a user-centric design interconnecting numerous devices belonging to a user in different geographic locations, such as home, office, car, etc., to form a single global network to offer fully personalized services. In PNs devices of the user move in different groups, where these groups merge and split. In this paper, we...journal article 2009

Derks, G. (author), Ebert, U. (author), Meulenbroek, B. (author)Streamer ionization fronts are pulled fronts that propagate into a linearly unstable state; the spatial decay of the initial condition of a planar front selects dynamically one specific long-time attractor out of a continuous family. A stability analysis for perturbations in the transverse direction has to take these features into account. In...journal article 2008

Agung, A. (author)In this thesis a conceptual design of an innovative high temperature reactor based on the fluidization principle (FLUBER) is proposed. The reactor should satisfy the following requirements: (a) modular and low power, (b)) large shutdown margin, (c) able to produce power when the bed of particles expands and stop as soon as the coolant flow is...doctoral thesis 2007

Boersma, G. (author), Sonnenschein, F.J. (author)Due to the finite stiffness of rotor- and gimbal-suspensions, a double gimballed momentum wheel will oscillate with high natural frequencies. The stability of these oscillations is studied, in order to obtain requirements for the stiffness of the suspensions and/or the gimbal inertia properties. From energy considerations, it is concluded that...report 1973
