In recent years the global energy demand has rapidly increased and will continue to grow in the next decades. With the growing demand for energy and the international agreement to use more renewable energy, the offshore wind industry is developing rapidly. This causes offshore wind farms to be installed at locations with larger water depths and...

Increasing the efficiency of wind farms is important for speeding up the transition from fossil fuels to renewable energy sources. Current wind farm control relies on maximization of power generation of individual turbines. However, research has demonstrated that plant-wide wind farm control could optimize the performance of a wind farm. Wind...

In order to track the speed profile, a case study using a linear quadratic regulator (LQR) is addressed in this paper. A time-invariant nonlinear train motion model is constructed. To apply LQR, the quadratic term of the aerodynamic drag and the rolling mechanical resistance is linearized. Gradient resistance, curve resistance, and other...

Treatment of early stage breast cancer is generally invasive to a patient's daily life while being treated. Therefore, to diminish the physical and psychological impact during and after recovery, a newly proposed minimally invasive therapy for early-stage breast cancer treatment is proposed. Within this study, this proposed treatment is modelled...

Fin Ray Effect (FRE) grippers have proven versatile and effective in pick & place automation applications. However, spherical and lateral round objects are still a challenge for the state-of-the-art, as solutions are unstable when placing those objects off-centre from the longitudinal line. Resulting in large and heavy FRE gripper assemblies...

The last few years have shown promising developments in single-molecule protein sequencing using a biological nanopore. Using only one membrane pore in a salt buffer, an applied potential creates a measurable ion current through the pore’s constriction. If a small molecule passes through the pore, this disruption is visible as a characteristic...

The rapidly growing number of renewable energy technologies has started changing the infrastructure of the conventional energy sector, which was based on one-directional power flow. Bidirectional flows are created in the network with the integration of renewable technologies. The electricity network and system operators face many new challenges...

In the last decades, the excessive increase in average global temperature related to a massive rise in greenhouse gas emissions showed the world how the fossil fuel society we live in today is drastically modifying and destroying the world we live in and is turning it in an un-habitable planet. Scientist all over the world made it clear that if...

In this report, we address the problems of water hammer and transient phenomena in water-filled pipes. Indeed, water hammer and vibrations cause troubles and damages on hydraulics installations. Here, we report a numerical approach to understand and avoid the problems inherent to these two phenomena. A Method Of Characteristics (MOC)...

The evolution of ice loads during the last Ice Age causes an ongoing Earth response with deformations and stress fields. The viscosity of the mantle depends on stresses, therefore the model stresses should be combined with ambient stresses such as due to mantle convection. This combination has been successfully simulated in the FEM software...

As the world is trying to rely less on fossil fuels for electrical energy. To do this, the alternatives should be as efficient and durable as possible. The alternative that has been growing the fastest in recent years is solar energy. Apart from it’s growth in the market share, the efficiency of photovoltaic (PV) cells has also steadily grown....

Destructive consequences of trapped space charges within HVDC coaxial cable insulation, such as accelerated aging, degradation, and breakdown, are some of the most significant challenges that manufacturers and users usually come up with. Pulsed Electro-Acoustic (PEA) method is a widely-used method for space charge detection and measurement, in...

Renewable energy sources (RES) such as Solar and Wind energy rely on the availability of natural resources like sunlight in the case of Solar and wind speed in the case of Wind energy generation which is variable in nature. There are periods where there is excess energy production than needed and periods of energy shortage where not enough...

Breast cancer, as one of the main causes of cancer death in the world, requires early detection to increase rate of survival. One idea is to develop a device that women could use at home to perform a regular self-check. Ultrasound is a safe, radiation-free technology that could be used for this device. Ultrasound systems (B-mode) that are...

The aim of this graduation thesis is to present a bipolar stepper motor semi-analytical model and compare its simulated motor dynamics. Stepper motor modeling has been successfully used to simulate motor performance and dynamics, yet, each modeling method holds advantages and disadvantages toward one another. In this thesis, the analytical...

The advancement of innovative PV technologies has led to an all-time high integration of the same in the urban environment. Furthermore, development of decentralized power systems complements this rise as it supports in-situ power consumption. Due to space availability constraints in urban environments and a need for appealing aesthetics,...

Many laboratory tests of samples where the rock fractures are based on<br/>meso-scale (cm) characterization of effective ‘intact’ strength parameters neglecting the microstructure effects. Understanding fracturing processes at<br/>micro-scale (mm) will require models with microstructure data. However,<br/>data is lacking on micro-scale.<br/...

Fossil fuel based energy systems are the main contributor to global warming. As new regulations come into place, a transition towards a more sustainable energy system must be realised. Hydrogen usage is regarded as the key enabler of such systems. The heart of these hydrogen-based energy systems (HESs) is the hydrogen back-up system (HBS) which...

A Solar Electric Vehicle is a vehicle that receives a significant amount of its total energy consumption through sunlight gathered using solar arrays. The main objective of this thesis was to determine how the design of the rear low-speed crash structures should be different for a Solar Electric Vehicle, compared to conventional cars. This is...
