1. 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.

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. 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.

5. Modulation, efficiency and lifetime of two-level and multilevel converters for a hydropower application
Abstract : Along with the integration of the renewable energy in the electrical grid, the pumped-storage hydropower has gained more and more attention due to its fast response and energy storage ability. To have a higher overall efficiency and more flexibility of the system, variable speed is preferred in the operation of the pumped-storage hydropower applications. READ MORE
