Distributed optimality
… schlage ich eine Synthese (Distributed Optimality, DO) von Optimalitätstheorie und einem derivationellen, morphologischem Asatz, Distributed Morphology (DM; Halle & Marantz, 1993) vor. Durch die Integration von OT in DM wird es möglich, Phänomene, die in DM durch sprachspezifische Regeln …

Fairness and optimality in trading
This thesis proposes a novel approach to address the issues of efficiency and fairness when multiple portfolios are rebalanced simultaneously. A fund manager who rebalances multiple portfolios needs to not only optimize the total efficiency, i.e., maximize net risk-adjusted return, but also …

Towards Human-Centered Optimality Criteria
… machines by people that can move us closer to HC optimality.

Weighted Optimality of Block Designs
Design optimality for treatment comparison experiments has been intensively studied by numerous researchers, employing a variety of statistically sound criteria. Their general formulation is based on the idea that optimality functions of the treatment information matrix are invariant to treatment …

OPTIMALITY OF CHEMICAL BALANCE WEIGHING DESIGNS.
… factorial designs. The well-known D-, A- and E-optimality criteria are obtained by taking (PHI)(X('T)X) = det(X('T)X)('-1), tr(X('T)X)('-1) and the maximum of the eigenvalue of (X('T)X)('-1) respectively. All these criteria are functions of the spectrum of X('T)X. Let …

Nonlinear multicriteria optimization and robust optimality
This dissertation attempts to address two important problems in systems engineering, namely, multicriteria optimization and robustness optimization. In fields ranging from engineering to the social sciences designers are very often required to make decisions that attempt to optimize several …

Adverb placement : an optimality theoretic approach
… (gap constructions, Part II) and to provide an Optimality Theoretic approach to the contrasts in the effects of these factors on the distribution of adverbs in English, French, and German. In Optimality Theory (Prince & Smolensky 1993), grammaticality is defined as optimal satisfaction of a …

Progressive place assimilation in optimality theory
… place agreement in clusters through the lens of Optimality Theory (Prince & Smolensky, 1993/2004; McCarthy & Prince, 1995, 1999). A large typology of such languages is presented and examined to detail a broad swath of phenomena. The main line of inquiry over this typology is how direction of …

River network scaling: optimality and anisotropy
… to growth mechanisms and from dynamics to optimality principles. The main contenders are dynamics and optimality, and the latter is controversial. The first part of my research is concerned with optimality theories of river networks. I distinguish between local and global optimality …

On the Optimality of the Lexicon
The principle of least effort posits that a pressure towards communicative efficiency shapes natural languages. In this thesis, we investigate the existence, the nature, and the impact of such a pressure in natural languages' lexicons. We investigate the existence of this pressure by (i) estimating …

Surpassing Local Optimality in Geometry Processing
Geometry processing is a diverse field studying questions such as how to represent a shape, how to modify a shape, and how shapes respond to perturbation. These questions lie at the heart of many applications in computational design, simulation, fabrication, and animation. We approach these …

General Weighted Optimality of Designed Experiments
… then able to generate a broad class of weighted optimality criteria that evaluate a design's ability to maximize the weighted information, ultimately targeting those designs that efficiently estimate effects assigned larger weight. This dissertation considers a much broader class of potential …

Connectedness and optimality in multidimensional designs
… be better than the old with respect to the S-optimality criterion. It is shown that the procedure can also be used in a two or more factor experiment to pg-connect an I-connected design for two factors. The new design obtained will be better than the old with respect to a new criterion, …

English loanwords in Thai and optimality theory
… and liquid alternation, within the framework of Optimality Theory (OT: Prince and Smolensky 1993/2004). The major objectives are: (1) to examine the way English loanwords are adapted to a new environment, (2) to investigate how conflict between faithfulness and markedness constraints is resolved …

Robustness and Optimality in CSMA Wireless Networks
In today's widely diffused CSMA wireless networks, problems of coordination in the access to the channel by multiple transmitters can lead to unfair situations where some of the flows receive much of the network throughput while others suffer from poor performance. As a solution to this problem, …

The structure of auctions : optimality and efficiency
The problem of constructing auctions to maximize expected revenue is central to mechanism design and to algorithmic game theory. While the special case of selling a single item has been well understood since the work of Myerson, progress on the multi-item case has been sporadic over the past three …

The n-tuple network: coping with sub-optimality
… important to understand the source of this sub-optimality and to develop the analytical tools that allow us to quantify the generalisation cost of using this model for any given data. We view RAMnets as classifiers and function approximators and try to determine how critical their lack of' …

Design principles for linear systems: Stability and optimality
… properties, such as stability and cost optimality. The first part addresses theoretical questions arising in the design of autonomous decentralized systems. The network topology of such a system describes which agents are able to interact with each other. We study the following problem: …
