Kok, J. (author)This thesis studies ways of broadening the range of a piezoelectric flow induced vibration harvester. The proposed device consists of a flap connected with a hinge to a spring. Existing harvesters are designed to replace or charge batteries for low power systems in the range of milliwatts. These systems produce low amounts of power, but for low...master thesis 2017

van der Vorst, H.M. (author)Congestion is one of the big annoyances people experience in their everyday life. Furthermore, congestion has negative effects on both the environment and the economy. In short, it forms a very big problem to society. This thesis focuses on a specific type of congestion, namely a ‘wide moving jam’. This is typically a short jam that propagates...master thesis 2017

ter Haar, O.A. (author)The increasing penetration of wind power generation introduces uncertainty in the behaviour of electric power grids. This work is concerned with the problem of day-ahead reserve scheduling (RS) for power systems with high levels of wind power penetration, and proposes a novel set-up that incorporates an alternating current (AC) Optimal Power...master thesis 2017

van den Hoorn, J.C. (author)Due to the increase of elderly people, the number of hip fractures rises as well. The most common hip fracture is an intertrochanteric fracture. This fracture is treated by inserting an intramedullary nail to support the fractured femur fragments. Before the intramedullary nail can be inserted, the bone fragments need to be realigned by...master thesis 2017

Dang, T.N. (author)A principal-agent problem is a mathematical framework for modelling contractual relationships, where a principal delegates tasks to an agent in exchange for reward. Many real life contracts are of this type. The agent does not have the same objectives as the principal and he possesses hidden information. Two types of hidden information is...master thesis 2017

Heslinga, M.A. (author)Corrective osteotomy is the treatment for malunion of bone segments, which is required after insufficient fracture management. To perform this procedure adequately, 3D imaging is used to make a virtual plan of the osteotomy. In order to transfer this virtual plan to the patient in the operating room, a navigation method is required. Existing...master thesis 2017

Evers, M. (author)Reaction Wheels (RWs), the primary attitude actuators on most spacecraft, are one of the largest on-board disturbance sources due to nondeterministic bearing behaviour at low angular velocities of the RWs. The configuration design of redundant Reaction Wheels Arrays (RWAs) can be divided into configuration optimization and control allocation....master thesis 2017

Mus, D.A. (author)In order to interact with environments and appliances made for humans, robots should be able to manipulate a large variety of objects and appliances in human environments. When having experience with manipulating a certain object or appliance, a robot should be able to generalize this behaviour to novel, but similar objects and appliances. When...master thesis 2017

de Winkel, J.F. (author)This thesis describes the development of the Delft Center for Systems and Control (DCSC) Networked Embedded Robotics Lab (NER) and a novel distributed formation control algorithm to showcase the lab’s experimental capabilities. The lab environment is built to support ground as well as aerial robotic platforms featuring a netted environment and...master thesis 2017

Monchen, G. (author)Adaptive Optics (AO) play an essential role in the field of astronomical seeing for ground-based telescopes, providing a corrected image from the disturbance caused by the light having to travel through the turbulent atmosphere of our Earth. To provide us with more detailed images, the sizes of these telescopes are getting increasingly larger....master thesis 2017

van de Leijgraaf, M. (author)Clients and vessel manufacturers are always looking for ways to increase the performance of their fleet. Therefore, a novel modelling strategy for the propulsion plant of naval vessels is explored here. This has been done by using the Linear Parameter Varying (LPV) framework. On one hand, a non-linear description is needed to fully understand...master thesis 2017

de Winter, A.J. (author)At this moment a revolution is going on in the development of our vehicles. The driver is going to be replaced by the vehicle itself. To investigate this autonomy Delft University of Technology (TU Delft) is project leader of a partnership called Dutch Automated Vehicle Initiative (DAVI). This group of industry and academics are combining their...master thesis 2017

Vlot, S.J. (author)In oil supply chains, crude oil needs to be transported from oil fields to refineries, and refined products need to be transported from refineries to regional depots. On land, pipelines are the preferred mode for long-distance oil transportation, because they are safe, efficient, silent, and cheap compared to other modes of transport. Pipelines...master thesis 2017

Roobeek, M. (author)Injuries are a sportsman’s worst nightmare: They withhold players from playing, they weaken teams and they force clubs to buy a bench-full of substitutes. On top of that, injuries can cause an awful lot of pain. Regulating match and training intensity can drastically decrease the risk of getting injured. Furthermore, it can optimally prepare...master thesis 2017

Frederik, J.A. (author)Renewable energy is becoming more and more important in today's society. Wind energy plays an important role in the production of renewable energy. Due to economic advantages, wind turbines are often sited close together, creating wind farms. As a result, the wind turbines in the farm become interconnected due to the wakes of the turbines. In...master thesis 2017

Lie, K.W.L. (author)Historically, the offshore industry has encountered difficulties in accessing their offshore assets safely. Especially during rough sea climates, people and cargo transfer from a ship to an offshore structure can be hard or even impossible due to wave induced vessel motions. For this, Ampelmann developed a ship-based, offshore access solution....master thesis 2017

Bijlsma, H.K. (author)Adaptive optics are often operated in wavefront-sensorless control fashion, since this requires no sensors. These devices often make use of piezoelectric actuators, which exhibit creep and hysteresis. In open loop operation, hysteresis and creep limit the performance. Hysteresis limits the precision of the compensation and creep reduces the...master thesis 2017

Keemink, H. (author)With the advent of smart thermostats like Toon®, detailed information about operation and usage of central heating boilers has become easily available. However, this information is not used in a systematic way by most companies including Eneco, and the wealth of information within is not available to the users. This has a few drawbacks. For...master thesis 2016

Zhang, X. (author)Model predictive control (MPC) is an advanced control technique that offers an elegant framework to solve a wide range of control problems (regulation, tracking, supervision, etc) and handle constraints on the plant. The control objectives and constraints are usually formulated as an optimization problem that the MPC controller has to solve ...master thesis 2016
