Soil liquefaction-induced uplift of buried pipes in sand-granulated-rubber mixture: Numerical modeling
(Elsevier, 2022-03)The significant uplift of buried pipes observed during recent earthquakes has showed the need for further research in remediation methods for soil liquefaction. Sand-granulated rubber mixture is reported as a new soil ... -
Numerical analysis of segmental tunnel linings - Use of the beam-spring and solid-interface methods
(Techno-Press (테크노프레스), 2022-04-16)The effect of segmental joints is one of main importance for the segmental lining design when tunnels are excavated by a mechanized process. In this paper, segmental tunnel linings are analyzed by two numerical methods, ... -
Application of large-scale optimization methods in scheduling and routing problems
In this thesis, we consider three different applications of large-scale optimization methods. We focus on the blood donation tailoring problem under uncertain demand in the first problem. In the second one, we propose a ... -
Solving 3-SAT problem using a quantum-simulated absorbing classical random walk approach
Quantum computing offers novel approaches for solving computationally hard problems. In this thesis, we present a quantum algorithm based on the quantum simulation of Schöning's algorithm for solving the 3-SAT problem. We ... -
