Model reduction for constrained mechanical systems via spectral submanifolds

Dynamical systems are often subject to algebraic constraints in conjunction with their governing ordinary differential equations. In particular, multibody systems are commonly subject to configuration constraints that define kinematic compatibility between the motion of different bodies. A full-scale numerical simulation of such constrained...

BENCHOP–SLV: The BENCHmarking project in Option Pricing–Stochastic and Local Volatility problems

In the recent project BENCHOP–the BENCHmarking project in Option Pricing we found that Stochastic and Local Volatility problems were particularly challenging. Here we continue the effort by introducing a set of benchmark problems for this type of problems. Eight different methods targeted for the Stochastic Differential Equation (SDE)...

Automation of Caeli: A High Performance Raman Lidar

Caeli is the CESARWater Vapour, Aerosol and Cloud Lidar and is a multiwavelength, high-performance Raman lidar which is stationed at the Cabauw Experimental Site for Atmospheric Research (CESAR) in the Netherlands. The instrument was developed as a key instrument for CESAR to strengthen the sites capabilities as a vertical profiling station. It...

Model Order Reduction for Non-Linear Structural Dynamics

Estimation of vehicle handling states

With the ever increasing demand of cars, safety is of prime concern to automobile manufactures across the world. Companies strive for the vision of "Zero accidents" through high quality and innovative products that reduce the frequency of accidents as well as their consequences. The auto industry has been exerting a myriad of state-of-the-art...

Investment decisions under uncertainties: A case of nuclear power plants

This thesis discusses the role of flexibility of decisions when investing in projects that are affected by economic uncertainties. It uses the theory of real options to value such investment decisions. The thesis focuses on investment decisions related to nuclear power plants, which usually are affected by several sources of economic...
