Generalized Constrained Interpolation
<p>Interpolation is essential in digital image processing, especially magnification. Many different approaches to interpolation specific to magnification have been developed in an effort to overcome the shortcomings of bilinear and bicubic interpolation. One of these approaches, Constraint-Based …

Constrained signal reconstruction
The research reported in this dissertation addresses the reconstruction of signals and images from linear measurements subject to convex constraints. The objectives are to describe the existence and uniqueness of solutions, to characterize reconstructions, and to develop algorithms for efficiently …

A space-constrained resource-constrained scheduling system for multi-story buildings
… proof of concept by developing SCaRC (Space Constrained and Resource Constrained) scheduling system. The system is implemented using a knowledge-based approach.

Cardinality Constrained Optimization Problems
In this thesis, we examine optimization problems with a constraint that allows for only a certain number of variables to be nonzero. This constraint, which is called a cardinality constraint, has received considerable attention in a number of areas such as machine learning, statistics, …

Minimal Norm Constrained Interpolation
… an extension of de Boor's work on minimal norm unconstrained interpolation.</p>

Fuel-constrained unit commitment
One of the main objectives in power system operation is the scheduling of resources in order to minimize the overall production cost. Through a wide range of scheduling activities, utility companies attempt to get maximum utilization of the available resources. However, the problem is a complex and …

Computer-aided constrained writing
… scientist. I shall investigate the how of constrained writing and the what of computer-aids through practical experimentation and observation. From these foundations I shall argue that computers need not impinge on human creativity and that a human:computer partnership may take advantage of …

Improvement of constrained searches
… memory, dependences. We study several cases of constrained search and present methods for improving their performance. Execution of Prolog programs amounts to a search with several types of dependences. We present a method for static reordering of goals in Prolog clauses, characterizing the …

Connectome-Constrained Artificial Neural Networks
… a set of guard rails by which function is constrained to solve tasks effectively, handle multiple stimuli simultaneously, adapt to noise and input variations, and preserve energy expenditure. Such features are desirable for artificial neural networks (ANNs), which are, unlike their organic …

Constrained Statistical Inference in Regression
<p>Regression analysis constitutes a large portion of the statistical repertoire in applications. In case where such analysis is used for exploratory purposes with no previous knowledge of the structure one would not wish to impose any constraints on the problem. But in many applications we are …

Robust and Constrained Dimension Reduction
… directions estimated by CANCOR or WCANCOR, a constrained CANCOR or WCANCOR method is also proposed in this dissertation. By the constrained WCANCOR method, each composite direction consists of only a subset of the explanatory variables for easier interpretation. When the estimated covariance …

Topics in shape-constrained inference
… topics of shape-restricted regression and shape-constrained density estimation. In the second chapter, we investigate the adaptation properties of the log-concave maximum likelihood estimator of a multivariate log-concave density. Our main theoretical results demonstrate that in certain …

Robust constrained model predictive control
(cont.) multiple Uninhabited Aerial Vehicles (UAVs) demonstrate that the new DMPC algorithm offers significant computational improvement compared to its centralized counterpart. The controllers developed in this thesis are demonstrated throughout in simulated examples related to vehicle control. …

Unreliable and resource-constrained decoding
… Decoders are also traditionally assumed to be unconstrained in physical resources like material, memory, and energy. This thesis studies how constraining reliability and resources in the decoder limits the performance of communication systems. Five communication problems are investigated. Broadly …

Search Techniques for Evolutionary Constrained Optimization
Solving Constrained Optimization Problems (COPs) has been an important research topic in the optimization, operation research, and computer science domains. Over the last few decades, evolutionary algorithms (EAs) have been widely adopted to solve such problems. However the main search operators of …
