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...

Daytime radiative cooling (DRC) is a very novel passive cooling method for buildings that utilises the recent technological advance in wavelength selective-emittance material research and takes advantage of a transparency window that exists in the atmosphere between 8 and 13 μm. Application of DRC in locations where warm weather prevails for...

A variable speed AC motor drive, fed by a 3-phase AC supply, often consists of a 3-phase bridge diode rectifier, a DC link capacitor and a pulse width modulated inverter. Recently, a new type of capacitor known as film capacitor or slim capacitor has become popular for use in DC link. This capacitor has a lower value of capacitance and a longer...

European policy makers have established a set of 20-20-20 targets for the year 2020 in the energy sector, goals based on security of supply, competitive markets and sustainability. The 3 key objectives include a 20% reduction of greenhouse gases (GHG) and CO2 compared to 1990 levels (and up to 80% by 2050), a 20% improvement in energy efficiency...

The development of the pole vaulting record is only improved by 1 centimeter over the last 25 years. Multiple studies show signs of different control strategies in elite pole vaulters, without pointing out what the cause of the differences is The aim of this research is to explore pole vaulting strategies by a control torque optimization. The...

In The Netherlands, the current heat energy system accounts for 44% of the primary energy usage and relies almost entirely on fossil fuels such as natural gas. To meet the Paris Climate Agreement goals, 4th Generation District Heating (4GDH) networks are expected as sustainable heat energy system solution. The concept relies on optimally...

The Classical model (or Cooke’s model) for elicitation and combination of expert judgments has been used in science and engineering since at least the early 1990’s. The most widely used program for applications of this model is EXCALIBUR. However, its code is not available for practitioners, which limits the accessibility and potential of the...

One way to implement a wind turbine in the sea is to use lattice structures. Since these structures are placed offshore, they must be able to withstand all kinds of loads. It is essential that the eigenfrequencies of the support structure do not correspond to the passing frequencies of the blades and any other dynamic actions. To avoid this the...

Geological surveying is a common practice performed by geologists nowadays. Determining layer orientation parameters and identifying folds are examples of features needed in order to create a geological map or model of the (sub) surface. Surveying is expensive and time consuming, therefore such survey is recently being investigated and...
