Urban land use and land cover classification with interpretable machine learning – A case study using Sentinel-2 and auxiliary data

The European commission launch of the twin Sentinel-2 satellites provides new opportunities for land use and land cover (LULC) classification because of the readily availability of their data and their enhanced spatial, temporal and spectral resolutions. The rapid development of machine learning over the past decade led to data-driven models being at the forefront of high accuracy predictions of t

Understanding of the Electrochemical Behavior of Lithium at Bilayer-Patched Epitaxial Graphene/4H-SiC

Novel two-dimensional materials (2DMs) with balanced electrical conductivity and lithium (Li) storage capacity are desirable for next-generation rechargeable batteries as they may serve as high-performance anodes, improving output battery characteristics. Gaining an advanced understanding of the electrochemical behavior of lithium at the electrode surface and the changes in interior structure of 2

Data standards for acute coronary syndrome and percutaneous coronary intervention : the European Unified Registries for Heart Care Evaluation and Randomised Trials (EuroHeart)

Standardized data definitions are essential for monitoring and benchmarking the quality of care and patient outcomes in observational studies and randomized controlled trials. There are no contemporary pan-European data standards for the acute coronary syndrome (ACS) and percutaneous coronary intervention (PCI). The European Unified Registries for Heart Care Evaluation and Randomised Trials (EuroH

Critical recurrence in real quadratic and rational dynamics

In this thesis we study the dynamics of real quadratic functions on the interval, and rational functions on the Riemann sphere. The problems we are considering are concerned with the recurrent nature of the critical orbit(s). In Paper I we investigate the real quadratic family and prove a theorem regarding the rate of recurrence of the critical point to itself, extending a previous result by Avila

Enhancement of 2DEG effective mass in AlN/Al0.78Ga0.22N high electron mobility transistor structure determined by THz optical Hall effect

We report on the free charge carrier properties of a two-dimensional electron gas (2DEG) in an AlN/AlxGa1-xN high electron mobility transistor structure with a high aluminum content (x = 0.78). The 2DEG sheet density N s = (7.3 ± 0.7) × 10 12 cm-2, sheet mobility μ s = (270 ± 40) cm2/(Vs), sheet resistance R s = (3200 ± 500) ω / □, and effective mass m eff = (0.63 ± 0.04) m 0 at low temperatures (

Standardization of Antigen-Emulsion Preparations for the Induction of Autoimmune Disease Models

Autoimmune murine disease models are vital tools for identifying novel targets and finding better treatments for human diseases. Complete Freund’s adjuvant is commonly used to induce disease in autoimmune models, and the quality of the adjuvant/autoantigen emulsion is of critical importance in determining reproducibility. We have established an emulsification method using a standard homogenizer an

InP/InAsP Quantum Discs-in-Nanowire Array Photodetectors: Design, Fabrication and Optical Performance

This thesis focuses on processing and electro-optical investigations of two- and three-terminal photodetectors based on large arrays of around three million n+-i-n+ InP nanowires with embedded InAsP quantum heterostructures for broadband detection. First, we investigated the optoelectronic behavior of two-terminal photodetectors under selective 980 nm excitation of the 20 axially embedded InAsP qu

Multi-modality Imaging Evaluation of a Rare and Complex Case of Single Ventricle Physiology; the important role of Cardiac MR

Congenital heart diseases (CHD) represent a major clinical and diagnostic challenge for correct abnormality identification and subsequent successful therapy; even more challenging is following-up patient health after multiple post-interventional corrections often required in complex cardio-vascular abnormalities. We describe a multi-modality imaging evaluation of a complex congenital cardio-vascul
