The restricted projection problems
… planes. In this thesis, I study the orthogonal projections of any set 𝐴 ⊂ R³ onto these restricted family of lines or planes.

On approximating projection games
The projection games problem (also known as LABEL COVER) is a problem of great significance in the field of hardness of approximation since almost all NP-hardness of approximation results known today are derived from the NP-hardness of approximation of projection games. Hence, it is important to …

Random Projection Optimal Trees Ensemble
… (RF), Optimal Trees Ensemble (OTE) and Random Projection Ensembles (RP) in high dimensional settings. To this end, LASSO has been considered for selecting the most important features based on training data for dimension reduction. Additionally, the influence of various hyper-parameters …

Prism : an answer projection system
Prism is an answer projection system that combines the best attributes of traditional and Web-based question answering systems. Traditional question answering systems retrieve answers with pinpoint accuracy but limited coverage, using a small and reliable data source, while Web-based systems …

Phase projection using three satellites
… We also introduce the notion of 2-D and 3-D Projection in our search for a simple, elegant solution to further reduce noise during our InSAR post-processing steps. 2-D Projection is shown to be a special case of 3-D Projection, and both require the presence of at least 3 satellites. …

Gradient projection anti-windup scheme
… problem. To this end, we propose the gradient projection anti-windup (GPAW) scheme, which is an extension of the conditional integration method to multi-input-multi-output (MIMO) nonlinear systems, using Rosen's gradient projection method for nonlinear programming. It achieves controller …

Architecture as model and projection
… is explored through questions of model and projection. These questions become more and more discernable as the model is built and photographed. The model is an analogue to a potential building. The drawings reveal the projective nature of architectural form. The photographs of the model …

Krylov Projection Methods for Model Reduction
… models for large, linear dynamic systems. Projections onto unions of Krylov subspaces lead to a class of reduced-order models known as rational interpolants. The cornerstone of this dissertation is a collection of theory relating Krylov projection to rational interpolation. Based on this …

Row Projection Methods for Linear Systems
Row projection (RP) methods for solving linear systems of equations are algorithms that require orthogonal projections onto the set of solutions of subsets of the equations. RP methods are categorized and their convergence properties summarized and extended. An implementation approach is presented …

Application of pressure-projection algorithms to a sharp projection immersed boundary method for the incompressible Navier-Stokes equations
… second-order accurate sharp immersed boundary projection method with an algebraic structure parallel to the classic fractional step method for the unsteady, incompressible Navier-Stokes equations. While second-order accuracy in time and space is generally achievable for the velocity components, …

Relational project modeling and risk projection framework
The relational project modeling and risk projection framework enables a projection of the consequences of initial project schedules and schedule changes with respect to risk realization in resource constrained project environments, and the identification of unrecognized schedule risks implied by …

FLOOD PROJECTION AND ANALYSIS THROUGH STOCHASTIC DOWNSCALING
… Climate Models, high resolution rainfall projections are not available. To this end, this study applies a novel stochastic downscaling method that was originally developed for rainfall nowcasting using radar data. In this study, the stochastic model was first modified to adapt the tropical …
