Historically, viruses have always been the causative agent of most human diseases. As one of the most devastating pandemics in human history, the COVID-19 pandemic, associated with SARS-CoV-2, is responsible for tens of millions of casualties in the world since the end of 2019. Meanwhile, it also has destabilized global economics. Therefore, in...

In this report the analysis of underwater communication using electric quasi-static fields is undertaken, in which key aspects that influence the performance the communication between a transmitting and receiving electrode is examined. A mathematical model was proposed for the transmission and reception of the quasistatic field and the expected...

The technology of focus in this paper, the applied-field magnetoplasmadynamic (MPD) thruster (AF-MPDT), was developed in the 1960s. However, little research has been conducted for this thruster. There is still the need for an accurate model describing the thruster's functioning, its thrust and the physical phenomenons inside.<br/>This project...

Coatings with dynamic surface structures are appealing to many applications like haptics and soft robotics. Restrictively, the speed of the surface dynamics in these coatings is often limited to frequencies below 1 kHz, which makes them unsuitable for applications like acoustics and communication optics. This work describes a method to create...

With the widespread application of power electronic switching technology, power equipment is facing new electrical stresses brought about by multilevel staircase voltages during testing and operation. Therefore, the partial discharge (PD) behavior of five typical defects in power equipment under the staircase waveform needs to be investigated...

In this study, a method for the bacterial disinfection of drinking water in the water storage systems based on the electric potential generated from a piezoelectric wind energy harvester is presented. First, an efficient galloping piezoelectric wind energy harvester is designed by adding curve- shaped attachments to the bluff body of the...

The effect of doping in Si3N4 membranes on the secondary electron yield is investigated using Monte Carlo simulations of the electron-matter interactions. The effect of the concentration and the distribution of the doping in silicon rich silicon nitride membranes is studied by using the energy loss function as obtained from ab initio density...

Semiconductor (SC)-based bulk absorbers operating in the (sub-) THz range are discussed. The conductivities of the bulk media are described by the Drude model for electron gas where the electron density is controlled. The Drude model predicts the existence of two frequencies of interest: one associated with the scattering time of the electrons...

The observable field is defined as the portion of the incident field that can contribute to the power received by an antenna. Recently, the observable field was estimated for a plane wave incidence. Here, the procedure is extended to a general incident field expressed as a superposition of homogeneous plane waves. The observable field concept...

The time domain-electric field integral equation (TD-EFIE) and its differentiated version are widely used to simulate the transient scattering of a time dependent electromagnetic field by a perfect electric conductor (PEC). The time discretization of the TD-EFIE can be achieved by a space-time Galerkin approach or, as it is considered in this...

Electroporation is a popular technique to permeabilize the membrane for different purposes such as medical treatments, food processing and biomass processing. In this thesis, we use the bottom-up approach to unravel the role of specific cellular components in the electroporation of cellular membranes. We have studied the role of the gel-phase...

The electricity demand is increasing with the development of industry. Nowadays, sustainable resources used for electricity generation are playing a more and more important role in the power system due to serious energy problems. Higher capability of power transmission and distribution thus becomes significantly necessary to keep the stability...

Geophysical methods are widely used for hydrocarbon exploration and time-lapse measurements. One method that can be applied in place of or in addition to the routinely used seismic method, is the Controlled-Source ElectroMagnetic (CSEM) method. The work described in this thesis explores various aspects to improve the land CSEM method for...

This paper describes a high-performance Capacitance-to-Digital Converter (CDC) for sub-nm displacement sensing with an electrically floating target. Intended to be integrated into a displacement sensor probe, the CDC consumes only 560μW. It achieves 98.5dB SNR in a 1ms conversion time, which is 34 times more energy-efficient than the prior...

In electrolyte solutions, an electric potential difference, called the Ionic Vibration Potential (IVP), related to the ionic vibration intensity, is generated by the application of an acoustic wave. Several theories based on a mechanical framework have been proposed over the years to predict the IVP for high ionic strengths, in the case where...
