1. Hrdina, Jan. Webová aplikace pro správu poznámek: Web Application for Managing Notes.

Degree: 2019, Brno University of Technology

The thesis deals with design and implementation of a web application for managing tree-structured notes. Its aim is to fulfill the true potential of using computers in this area. It tries to achieve this goal using (1) multiple ways of viewing and editing one data, (2) focusing the data-model primarily on the meaning of stored information instead of appearance and (3) implementing tools for interactive work with text (e.g. attaching multimedia). Apart from the application design itself, the text briefly goes through modern trends in web applications development, it defines the basic concepts in relation to existing tools for managing notes and outlines wide possibilities of further development. The application itself was implemented using technologies such as Polymer, TypeScript or Firebase. Advisors/Committee Members: Burget, Radek (advisor), Očenášek, Pavel (referee).

2. Johnson, Torrey (Torrey Allen). Branching random walk and probability problems from physics and biology.

Degree: PhD, Mathematics, 2012, Oregon State University

This thesis studies connections between disorder type in tree polymers and the branching random walk and presents an application to swarm site-selection. Chapter two extends results on tree polymers in the infinite volume limit to critical strong disorder. Almost sure (a.s.) convergence in the infinite volume limit is obtained for weak disorder by standard theory on multiplicative cascades or the branching random walk. Chapter three establishes results for a simple branching random walk in connection with a related tree polymer. A central limit theorem (CLT) is shown to hold regardless of polymer disorder type, and a.s. connectivity of the support is established in the asymmetric case. Chapter four contains a model for site-selection in honeybee swarms. Simulations demonstrate a trade-off between speed and accuracy, and strongly suggest that increasing the quorum threshold at which the process terminates usually improves decision performance. Advisors/Committee Members: Waymire, Edward C. (advisor), Thomann, Enrique A. (committee member).

3. Alapati, Sridhar. Studies on Electrical Treeing in High Voltage Insulation Filled with Nano-Sized Particles.

Degree: PhD, Faculty of Engineering, 2018, Indian Institute of Science

Polymers are widely used as insulating materials in high voltage power apparatus because of their excellent electrical insulating properties and good thermomechanical behavior. However, under high electrical stress, polymeric materials can get deteriorated which can eventually lead to the failure of the insulation and thereby the power apparatus. Electrical treeing is one such phenomena whereby dendritic paths progressively grow from a region of high electrical stress and branch into conducting channels in a solid dielectric. The propagation of electrical trees is of particular interest for the power industry as it is one of the major causes of failure of high voltage insulation especially in high voltage cables, cast resin transformers as well as rotating machines. To improve the life time of the electrical insulation systems there is a need to improve the electrical treeing resistance of the insulating material for high voltage application. With the development of nanotechnology, polymer nanocomposites containing nano sized particles have drawn much attention as these materials are found to exhibit unique combinations of physical, mechanical and thermal properties that are advantageous as compared to the traditional polymers or their composites. Literature reveals that significant progress has been made with respect to the mechanical, optical, electronic and photonic properties of these functional materials. Some efforts have also been directed towards the study of dielectric/electrical insulation properties of these new types of materials. Considering the above facts, the present research work focuses on utilizing these new opportunities which have been opened up by the advent of nanocomposites to develop tree resistant insulating materials for high voltage power applications. Electrical treeing is a common failure mechanism in most of the polymeric insulation systems and hence electrical treeing studies have been carried out on two types of polymers (viz. polyethylene used in high voltage cable and epoxy used in rotating machines and resin cast transformers) along with three different types of nano-fillers, viz. Al2O3, SiO2 and MgO and with different filler loadings (0.1, 1, 3, 5 wt%). Furthermore, considering the fact that electrical treeing is a discharge phenomenon, the partial discharge characteristics during electrical tree growth in polymer nanocomposites was studied. As morphological changes in the polymer influence the electrical tree growth, the influence of nano-particle induced morphological changes on the electrical treeing has also been studied. Above all, an attempt has also been made to characterize and analyze the interaction dynamics at the interface regions in the polymer nanocomposite and the influence of these interface regions on the tree growth phenomena in polymer nanocomposites. A laboratory based nanocomposite processing method has been successfully designed and adopted to prepare the samples for treeing studies. Treeing experimental results show that there is a significant improvement… Advisors/Committee Members: Thomas, Joy M (advisor).
