Mathematical modelling of dominance hierarchies
… research we analyse the formation of dominance hierarchies from different viewpoints and various models of dominance hierarchy formation have been proposed, one important class being winner--loser models and another being Swiss tournaments. We start by understanding the structure of hierarchies …

Abstraction Hierarchies for Multi-Agent Pathfinding
<p>Multi-Agent Pathfinding is an NP-Complete search problem with a branching factor that is exponential in the number of agents. Because of this exponential feature, it can be difficult to solve optimally using traditional search techniques, even for relatively small problems. Many recent optimal …

The Forbidden Pattern Approach to Concatenation Hierarchies
… dot-depth problem can be captured formally by hierarchies of classes of star-free regular languages B(0), B(1/2), B(1), B(3/2),... and L(0), L(1/2), L(1), L(3/2),.... which are defined via alternating the closure under concatenation and Boolean operations, beginning with single alphabet …

Complexity hierarchies in generalized descriptive set theory
… we conduct a systematic analysis of several hierarchies of classes of sets and functions. At the level of sets, we study the Borel hierarchy, the difference hierarchy, and the Wadge hierarchy; at the level of functions, we examine the Baire class hierarchy as well as the class of …

INFERENCE OF HIDDEN HIERARCHIES FROM OBSERVABLE NETWORKS
… reconstruction. The second part focuses on hierarchies, as we need clear understanding of what hierarchy means. We discuss why they are important within the network reconstruction framework. Chapter 2 goes through the specific characterizations for hierarchies and hierarchical systems I pick …

Challenging identity hierarchies in Julie Taymor’s Tempest
<p>Julie Taymor’s The Tempest was released in 2010 and received mixed critical response though almost all critics lauded Helen Mirren’s performance as Prospera, the first female Prospero in a major film. In the spirit of the original, almost all of the dialogue is Shakespeare’s save for some …

Exploiting multiprocessor memory hierarchies for operating systems
… of the performance of multiprocessor memory hierarchies for operating systems. The operating system instruction cache misses are reduced by 81% using a code reorganization scheme tailored to the operating system, guarded sequential prefetching, and stream buffers. The operating system data …

Genomic variety estimation with Bayesian nonparametric hierarchies
The recent availability of large genomic studies, with tens of thousands of observations, opens up the intriguing possibility to investigate and understand the effect of rare genetic variants in biological human evolution as well as their impact in the developement of rare diseases. To do so, it is …

Forbidden-Patterns and Word Extensions for Concatenation Hierarchies
… dot-depth. This measure leads to concatenation hierarchies like the dot-depth hierarchy (DDH) and the closely related Straubing-Thérien hierarchy (STH). The question whether the single levels of these hierarchies are decidable is still open and is known as the dot-depth problem. In this thesis …

Due Distinction: Elite Student Status Hierarchies In China
… the United States conceptualizes student status hierarchies as multidimensional systems. Scholars portray multidimensional status systems as exclusionary, constructed by and in the best interests of high status students, and disconnected from adult society. However, these theories are less useful …

Simplifying and deforming through hierarchies of simplicial grids
This thesis consists of three parts. In the first part we study the maintenance of a simplicial grid under changing density requirements. The proposed method works in any fixed dimension and generates grids by projecting cross-sections of a monotone simplicial complex that lives in one dimension …

Efficient coherence and consistency for specialized memory hierarchies
… state-of-the-art approaches for designing memory hierarchies of heterogeneous systems, and shows that the current techniques provide neither efficiency nor programmability for emerging workloads. We demonstrate how DeNovoA with a DRFrlx memory consistency model improves efficiency and …

A Qualitative Examination Of Social Hierarchies Among Young Children
… were observed to decipher how cliques and hierarchies were displayed among groups of young children aged three to six. Participants were 16 pre-kindergarten children, four core staff members, three student teachers, and nine student workers or practicum students in a laboratory classroom …

Learning image segmentation and hierarchies by learning ultrametric distances
In this thesis I present new contributions to the fields of neuroscience and computer science. The neuroscientific contribution is a new technique for automatically reconstructing complete neural networks from densely stained 3d electron micrographs of brain tissue. The computer science …

Hegemony, marginalisation, and hierarchies: Masculinities in contemporary Pakistani anglophone fiction
By being empowered as subjects, authors of Pakistani anglophone fiction present a more nuanced, layered, and complex picture of Pakistan than the Western hegemonic discursive construction of the country as a hub of terror. Contemporary Pakistani anglophone fiction provides an insight into the …

Interactive visualization of information hierarchies and applications on the web
<p>The visualization of information hierarchies is concerned with the presentation of abstract hierarchical information about relationships between various entities. It has many applications in diverse domains such as software engineering, information systems, biology, and chemistry. Information …

Structural analysis and auditing of SNOMED hierarchies using abstraction networks
… more effectively and efficiently. Large SNOMED hierarchies are partitioned, based primarily on their relationships patterns, into concept groups of more manageable sizes. Three related abstraction networks with respect to a SNOMED hierarchy, namely the area taxonomy, partial-area taxonomy, and …

Dissolving differences: Law and water's role in legitimizing global hierarchies
We live under the false illusion that there is an infinite supply of water on earth. In reality, quantities of available freshwater have remained constant for at least 2000 years while the global population has increased 33 fold during this same period. Rainfall remains the only form of renewable …

Semantic and data-driven hierarchies for personalized models of affect
… Past studies have indicated that semantic hierarchies along demographic divisions perform well in estimating affect. This work focuses on comparing these semantic groupings to data-driven hierarchies. A key question is whether data-driven hierarchies can provide additional ways of …
