Approximations to optimal feedback control using a successive wavelet collocation algorithm
C. Park,Panagiotis Tsiotras +1 more
TL;DR: A successive wavelet collocation algorithm that uses interpolating wavelets in a collocation scheme to iteratively solve the generalized-Hamilton-Jacobi-Bellman (GHJB) equation and the corresponding optimal control law is proposed.
Dissertation
Effective and Efficient Methodologies for Social Network Analysis
TL;DR: An anytime-anywhere methodology based on a parallel/distributed computational framework to effectively and efficiently analyze large and dynamic social networks and implements its methodology for a set of SNA metrics which are significant for SNA applications and cover a wide range of difficulties.
Automated assessment of English-learner writing
TL;DR: This thesis argues that an approach which does not rely on task-dependent components or data, and directly assesses learner English, can produce results as good as promptspecific models, and presents a user interface that visualises and uncovers the ‘marking criteria’ represented in AA models.

On the efficient realization of sparse matrix techniques for integral equations with focus on panel clustering, cubature and software design aspects
TL;DR: The boundary element method (BEM) is an elegant tool for solving elliptic boundary value problems numerically by transforming the PDE on a domain Ω into an integral equation defined on the boundary of Ω, where the dimension of the stiffness matrix is much smaller as for the corresponding FE-discretization.

Web user profiling on proxy logs and its evaluation in personalization
TL;DR: A hierarchical URL dictionary generated from Yahoo! Directory and a cross-hierarchical matching method that provides the function of automatic abstraction are developed that are used to analyze web access actions that are monitored through a web proxy.
