Methods of Approximation in hpk Framework for ODEs in Time Resulting from Decoupling of Space and Time in IVPs
In the initial value problems (IVPs) describing evolutions, the dependent variables naturally exhibit simultaneous dependence on spatial coordinates and time. Thus, space-time coupled methods of approximation are rather natural for obtaining numerical solutions of the mathematical models (IVPs) …

Design of spatial interfaces for engineering assembly within a virtual environment for automotive design
… one-handed spatial interface. The VE is the IVPS (Interactive Virtual Prototyping System) at University of Leeds, which supports interactive engineering assembly. The main contribution of this research is to demonstrate an improved understanding of task performance for engineering assembly. …

Nonhomogeneous Initial Boundary Value Problems for Two-Dimensional Nonlinear Schrodinger Equations
… Compared with pure initial value problems (IVPs), IBVPs over part of entire space with boundaries are more applicable to the reality and can provide more accurate data to physical experiments or practical problems. Although there is less research that has been made for IBVPs than that for …

Reachability and robust design in dynamic systems
… models of interest are initial value problems (IVPs) in ordinary differential equations (ODEs). In the case of reachability analysis, the focus is on efficiently calculated enclosures or "bounds" of the reachable sets, since one motivating application is to (deterministic) global dynamic …

Finite difference methods for 1st Order in time, 2nd order in space, hyperbolic systems used in numerical relativity
… the discretization of initial value problems (IVPs) and initial boundary value problems (IBVPs) of certain hyperbolic systems which are first order in time and second order in space. This type of system appears in some formulations of Einstein equations, such as ADM, BSSN, NOR, and the …

An ODE solver for constrained state spaces: with applications to hybrid-system simulations
This thesis presents a solver to handle constrained-state-space ODEs. This solver locates the points where any of the states go outside of the constraining set, and then, transfers the control from the continuous time ODE to the function governing the behavior of the system on the boundaries of the …
