Validation of Sequentially Linear Analysis for Quasi-Brittle Behaviour of Reinforced Concrete Structures under Proportional and Non-Proportional Loading

The aim of this thesis was to objectively and quantitatively assess the accuracy and robustness of two-dimensional sequentially linear analysis (SLA) in comparison to nonlinear finite element analysis (NLFEA), for a range of experiments of reinforced concrete structures with proportional and non-proportional loading schemes. Non-proportional...

Redesign of the Solution Algorithms in Wanda

The Wanda software package developed by Deltares can used for simulating both steady state and transient fluid flow in pipeline systems. Steady state simulations are used for initial system design and transient flow simulations are used for doing water hammer analysis in pipeline systems. For both types of simulations a system consisting of both...

Detection and quantification of lateral, illicit connections and infiltration in sewers with Infra-Red camera: conclusions after a wide range of experiments

The most known problem of separate sewer systems is the existence of illicit connections and, hence, the deposition of untreated sewage to the receiving waters or the occurrence of urban flooding due to overloading of wastewater systems with storm water. Although there are several known and relative expensive techniques for inspection of storm...

Stability, Accuracy, and Robustness of the Time Domain Integral Equation Method for Radar Scattering Analysis

The aim of this thesis is to design a computational method that can be used in modern stealth technology. In particular, the computational method should be capable to simulate scattering of ultra-wideband radar signals for military aircraft constructed with ferromagnetic radar absorbent materials. A full-wave boundary element method has been...
