1. From Words to Voids : Absencing and Haunting in Crimean Semiotic Landscapes
Abstract : This thesis seeks to contribute to the body of ethnographically-oriented semiotic landscape research by addressing linguistic and non-linguistic signs in the landscapes of contemporary Crimea. It is based on research conducted in the region back in 2017 and 2019 after the Russian annexation but before the full-scale war against Ukraine, which started on 24 February 2022. READ MORE

2. Processability of Laser Powder Bed Fusion of Alloy 247LC-Influence of process parameters on microstructure and defects
Abstract : This thesis is about laser powder bed fusion (L-PBF) of the nickel-basedsuperalloy Alloy 247LC. Alloy 247LC is mainly used in gas turbine blades and processing the blades with L-PBF may confer performance advantage over the blades manufactured with conventional methods. READ MORE

3. Connected by voids: Interactions and screening in sparse matter
Abstract : Using theory and computations, we study structural and electronic properties of nanoscale systems where regions of low density are important for response and function. Materials with such properties are called sparse matter. Examples include assemblies of organic molecules and layered structures like graphite. READ MORE

4. Evaluation of Asphalt Field Cores with Simple Performance Tester and X-ray Computed Tomography
Abstract : The importance of aggregate structure and air voids distribution for asphalt mixture rutting and cracking performance has been well established on the basis of experience and is well documented in the literature. Past and current investigations are limited to assessment of performance based on macroscopic behavior due to the difficulty associated with the quantitative measurement and analysis of the internal structure of asphalt mixtures.
