Recently, by Z. Shen, resolvent estimates for the Stokes operator were established in <i>L<sup>p</sup>(Ω) </i>when <i>Ω</i> is a Lipschitz domain in <i>R<sup>d</sup></i>, with <i>d≥3</i> and<i> |1/p-1/2|&lt;1/(2d)+ε</i>. This result implies that the Stokes operator generates a bounded analytic semigroup in <i>L<sup>p</sup>(Ω)</i> in the case...

In this study, a analysis was performed to analyze why there are differences in port configuration between IPv4 and IPv6. For this, the current state of adoption and implantation processes of IPv6 were researched. Currently, 4,8% of all dual-stack hosts have a different configuration in open ports on IPv4 and IPv6. To discover the reasoning...

Over the years, the Leipzig Wind Profile observed under near neutral condition has been considered as an essential benchmark for idealized friction layer models. However, the general weather condition for the Leipzig Wind Profile still remains a mystery after nearly 90 years. In order to simulate this event and try to recreate the weather...

Flame flashback is an intrinsic problem in lean premixed combustion. Due to higher flame speeds and lower quenching distances, hydrogen-rich fuel mixtures are especially prone to boundary layer flashback (BLF). Research at TU Munich (Eichler 2011, Baumgartner 2014) has resulted in new insights into the mechanism of BLF, revealing a strong...

Today's leading projections of climate change predicate on Atmospheric General Circulation Models (GCMs). Since the atmosphere consists of a staggering range of scales that impact global trends, but computational constraints prevent many of these scales from being directly represented in numerical simulations, GCMs require "parameterisations'' -...

Hydrogenated Indium Oxide (IOH) has been recognized as a high performance transparent conductive oxide (TCO) due to its excellent mobility (&gt;100 cm2/Vs) and high transparency (&gt;90%) in the visible and near infrared region of the spectrum. Plasma enhanced spatial atomic layer deposition (PESALD), a new type of deposition process developed...

The multi-pole PML (MPML) is tested on models that simulate seismic waves traveling through the subsurface. Using a recursive integration technique a stretching function consisting of the sum of multiple stretching functions is implemented in the velocity-stress finite difference time domain wave equations. The MPML is implemented in both the...

Framed in the current trend of global energetic efficiency, active drag reduction techniques in water vehicles have regained popularity in the last decades thanks to the intense research in the air lubrication approach. Within the last decade, bubbly drag reduction has yielded its place to air layer drag reduction, in which a thin, continuous air...

After the failure of several large breakwaters in late 1970’s and early 1980’s where the role of rocking and breakage of armour became apparent, the importance of understanding this rocking phenomenon is given a great emphasis. Single layer randomly placed armour units are widely used in breakwater designs as they are more economical due to the...

The non-linear relation between Evapotranspiration (ET) and the atmospheric moisture demand in terms of vapor pressure deficit (VPD) has been widely reported. Observations point towards a diverse range of potential drivers; however, without uncovering why the identified factors are found to control diurnal ET-VPD hysteresis. Modelling efforts...

This project is an attempt to bring back play, from the mere simulation it is now, to a creative force that it once was. It questions whether the entertainment park is still relevant in contemporary society and whether it can be reimagined and transformed from a scripted to a more unscripted arena of action. The aim of this project is to create...

The Low Earth Orbit (LEO) region has been attractive to many space agencies and organisations because of its ease of access and the ideal opportunity for remote sensing. Due to the low altitudes, a satellite's orbital state is highly affected by the atmospheric drag force acting on the satellite's body. The largest variation in this drag force...

Stratiform precipitation is one of the most important precipitation systems in the mid-latitudes. To gain understanding of the melting layer, which is part of a stratiform precipitating system, an algorithm which is able to select melting layer data from large datasets is required. The goal of this thesis work is to create and deliver a program...

Aircraft fuel efficiency, noise, and emissions are some of the most important aspects being addressed in the research of novel aircraft configurations for meeting the future requirements of the aviation industry. One concept which has the potential for improving the aircraft fuel efficiency is called the boundary layer ingestion (BLI)....

A highly accurate model is presented that predicts boundary layer flashback (BLF) for lean premixed hydrogen combustion. In contrast to existing models, that fail for lean hydrogen mixtures, the present model includes the effect of flame instabilities. The model is applied to study the effect of burner geometry on flashback tendency. A diverging...

Shock-Wave/Turbulent-Boundary Layer Interactions (SWTBLI) often occur in applications of technological interest. The associated inherent low-frequency unsteadiness dictates the use of Large-Eddy Simulation (LES) approaches to resolve the interaction, which unavoidably implies a very high computational cost. For this reason, no well-resolved long...

As countries around the world are in a race for clean energy, various renewable energy sources are harvested to meet the energy needs. In Western Europe, wind energy is the primary source of renewable energy. To meet the energy demand, higher capacity wind turbines are being installed in deeper waters. In deep waters, monopile foundations are...

The boundary layer transition location is a crucial design parameter in aerodynamics. The computational prediction of boundary layer transition in engineering applications is typically based on empirical models. These models require experimental measurements for calibration and validation purposes. For unsteady aerodynamic processes, the range...

Natural Organic Matter (NOM) is always present in the drinking water sources such as rivers, lakes and reservoirs. It causes several problems, including the unfavourable colour and odour of water, formation of disinfectant by-products and harmful microbial growth. In drinking water treatment, anion exchange (anion-IEX) is used for NOM removal....

Hydrocarbon or geothermal reservoir often consists of several rock layers from different lithology. The various lithologies have their own number of mechanical properties and the layering effect introduced the term of mechanical contrast, which represents the ratio of rock strength between adjacent layers. Mechanical contrast and confining...
