Aegean Linear Script(s): Rethinking the Relationship between Linear A and Linear B
… investigates the genetic relationship between Linear A and Linear B (henceforth LA, LB), two Bronze Age scripts attested on Crete and Mainland Greece and understood to have developed one straight out of the other. By using an interdisciplinary methodology, I integrated linguistic, epigraphic, …

Programação contínua: propriedades das soluções
… as a continuous version of discrete problems in linear programming. First we treat the case in which the constraints are linear, in the space of bounded Lebesgue-measurable functions, presenting results involving extensive use of duality. To treat the case when the constraints are not linear, a …

A modified Posicast method of control with applications to higher order systems.
… mechanism of the posicast control is completely linear. A step command is divided into two parts. In general, the second part must follow the first part by nearly one-half cycle of the transient. The total transient time is limited to about one-half cycle. There is no transient overshoot and the …

The Undeciphered Signs of Linear B
… years after Michael Ventris’ decipherment of the Linear B script, 14 of its 87 syllabic signs still have no sound-values assigned to them. This group of ‘undeciphered’ signs represent a significant gap in our ability not only to read the Linear B script, but also to understand its development and …

Ultracold Rydberg Atoms in Structured and Disordered Environments
… few-body interactions and the dynamics of the linear A-B-A trimer, where A is the ground-state atom and B is the Rydberg atom, were investigated in the framework of normal mode analysis. This exotic ultralong-range triatomic bound state exists despite that the Rydberg-ground-state interaction …

Synthesis and characterization of linear and star-branched butadiene-isoprene block copolymers and their hydrogenated derivatives
… to synthesize and hydrogenate well-characterized linear and star-branched block copolymers based on butadiene and isoprene. Sequential anionic addition techniques initiated by homogeneous organolithium species in hydrocarbon solvents were employed to prepare several series of butadiene-isoprene …

Improving Computation for Hierarchical Bayesian Spatial Gaussian Mixture Models with Application to the Analysis of THz image of Breast Tumor
… how to incorporate spatial autocorrelation in linear a regression model with an emphasis on the computational framework for estimating the spatial correlation patterns. </p> <p>The third chapter starts with an overview of Gaussian mixture models (GMMs). However, because in the GMM framework the …

Modeling Stem Taper of Southern Appalachian Red Spruce
… in southern Appalachian red spruce: a simple linear, a quadratic polynomial, a segmented, a variable exponent, and a geometric model. Based on past studies and our results, we found that the best equations to use were the variable exponent and segmented polynomial models. Users should consider …

Nonparametric prediction in survey sampling and its application to the nonresponse problem
… the GSE, and the probability response model. The linear regression model is ubiquitous in the sample survey literature, an assumption that is untenable in practice. In this dissertation we illustrate that it is feasible to estimate a finite population mean (also in the presence of nonresponse) …

Methods for Control in Robotic Excavation
… behaviour of earth and fragmented rock highly nonlinear and distributed but also the terrain profiles and properties of excavation sites are uncertain, unstructured, and non-uniform. In this thesis new methods are presented and tested to tackle the current limits in robotic excavation arising from …

A hybridized discontinuous Galerkin formulation for modeling electrohydrodynamic thrusters
… The problem is two-way coupled and non-linear. A smoothed charge injection model from the literature for the corona discharge is included in the HDG scheme. The formulation is validated against a model problem which has an analytical solution and parallel wire single stage and dual stage …

The Origins of Writing, and its Relation to Art on Bronze Age Crete
… existence of other, as of yet unidentified, linear writing systems on Crete. This is followed by a study of the Cretan Hieroglyphic writing system; the unjustified omission of supposedly ‘decorative’ signs in many of its documents is identified, the script’s corpus nearly doubled, and ‘a …
