1. Fractal superconducting resonators for the interrogation of two-level systems
Abstract : In this thesis we use high-Q superconducting thin-film microwave resonators to interact with several types of quantum mechanical two-level systems. Such a resonator is used as the central building block in a cryogenic near-field scanning microwave microscope (NSMM) to reach a completely new regime of NSMM operation. READ MORE

2. Modeling pooling and perishable items in inventory systems
Abstract : This thesis is built on three papers considering different problems in inventory control. The first paper considers a two-location newsboy model with the possibility of making lateral transshipments when needed. Usually, when considering newsboy models it is assumed that all demand in a period occurs at once. READ MORE

3. Superinductance and fluctuating two-level systems: Loss and noise in disordered and non-disordered superconducting quantum devices
Abstract : In this thesis, we first demonstrate that a disordered superconductor with high kinetic inductance can realise a microwave low-loss, non-dissipative circuit element with impedance greater than the quantum resistance. This element, known as a superinductor, can suppress the fluctuations of charge in a quantum circuit. READ MORE

4. Two-Level Multi-Objective Genetic Algorithm for Risk-Based Life Cycle Cost Analysis
Abstract : Artificial intelligence (AI) is one of the fields in science and engineering and encompasses a wide variety of subfields, ranging from general areas (learning and perception) to specific topics, such as mathematical theorems. AI and, specifically, multi-objective genetic algorithms (MOGAs) for risk-based life cycle cost (LCC) analysis should be performed to estimate the optimal replacement time of tunnel fan systems, with a view towards reducing the ownership cost and the risk cost and increasing company profitability from an economic point of view.

5. Compiler Generation for Data-Parallel Programming Languages from Two-Level Semantics Specifications
Abstract : This thesis is an empirical study of compiler generation for data-parallel languages from denotational-semantics-based formal specifications. We investigate whether compiler generation from such specifications is practical, not only with respect to generation of practical compilers, but also with respect to compilation of programs into efficient code and execution of the compiled programs on massively parallel SIMD (Single Instruction Multiple Data) architectures.
