The Crustal Thickness Of West Antarctica, Julien A. Chaput, Richard C. Aster, Audrey D. Huerta, X. Sun, Andrew Lloyd, Douglas A. Wiens, Andrew Nyblade, Sridhar Anandakrishnan, J. Paul Winberry, Terry Wilson

Geological Sciences Faculty Scholarship

P-to-S receiver functions (PRFs) from the Polar Earth Observing Network (POLENET) GPS and seismic leg of POLENET spanning West Antarctica and the Transantarctic Mountains deployment of seismographic stations provide new estimates of crustal thickness across West Antarctica, including the West Antarctic Rift System (WARS), Marie Byrd Land (MBL) dome, and the Transantarctic Mountains (TAM) margin. We show that complications arising from ice sheet multiples can be effectively managed and further information concerning low-velocity subglacial sediment thickness may be determined, via top-down utilization of synthetic receiver function models. We combine shallow structure constraints with the response of deeper layers using a …

Asymptotic Multi-Layer Analysis Of Wind Over Unsteady Monochromatic Surface Waves, Shahrdad Sajjadi, Julian Hunt, Frederique Drullion

Publications

Asymptotic multi-layer analyses and computation of solutions for turbulent flows over steady and unsteady monochromatic surface wave are reviewed, in the limits of low turbulent stresses and small wave amplitude. The structure of the flow is defined in terms of asymptotically-matched thin-layers, namely the surface layer and a critical layer, whether it is ‘elevated’ or ‘immersed’, corresponding to its location above or within the surface layer. The results particularly demonstrate the physical importance of the singular flow features and physical implications of the elevated critical layer in the limit of the unsteadiness tending to zero. These agree with the variational …

Polarization-Coupled Transport Behavior In Ultrathin Ferroelectric Heterostructures, Haidong Lu

Department of Physics and Astronomy: Dissertations, Theses, and Student Research

Ferroelectric polarization-coupled resistive switching behavior in ferroelectric tunnel junctions (FTJs), the tunneling electroresistance (TER) effect, is a recently predicted new phenomenon, which attracts interest due to potential application in the next generation non-volatile ferroelectric random access memories (FeRAMs). In this dissertation, we demonstrate the TER effect in FTJ devices by means of scanning probe microscopy (SPM) techniques. We have investigated several device configurations for enhancement of polarization stability and for demonstration of the resistive switching behavior: (i) using the SPM probe as a top electrode; (ii) using heterostructures with engineered interfacial atomic terminations; (iii) using metal electrodes; (iv) adding an …

Electrochemical And Surface Compositional Studies On Uranium Dioxide, Mayuri Razdan

Electronic Thesis and Dissertation Repository

This thesis describes electrochemical and surface compositional studies performed on a number of simulated nuclear fuel (SIMFUEL) materials under conditions relevant to permanent disposal of spent nuclear fuel in a geologic repository. This is important since a number of critical issues have been identified in the event of waste container failure. The research performed was mainly focused in three areas: (i) the influence of low pH on the surface chemistry of UO₂, since acidity could develop within corrosion product deposits and flaws in the fuel; (ii) the combined influence of dissolved H₂ and H₂O_{2 …}

Prescribed Fire Effects On Resource Selection By Cattle In Mesic Sagebrush Steppe. Part 1: Spring Grazing, Patrick Clark, Jaechoul Lee, Kyungduk Ko, Ryan Nielson, Douglas Johnson, David Ganskopp, Joe Chigbrow, Frederick Pierson, Stuart Hardegree

Kyungduk Ko

Prescribed fire is commonly applied world-wide as a tool for enhancing habitats and altering resource-selection patterns of grazing animals. A scientific basis for this practice has been established in some ecosystems but its efficacy has not been rigorously evaluated on mesic sagebrush steppe. Beginning in 2003, resource-selection patterns of beef cows were investigated using global positioning system (GPS) collars for 2 years before and for 5 years after a fall prescribed burn was applied to mesic sagebrush steppe in the Owyhee Mountains of southwestern Idaho, USA. Resource-selection functions (RSF) developed from these data indicated cattle selected for lightly to moderately …

Ancestor Worship In The Logic Of Games. How Foundational Were Aristotle's Contributions?, John Woods

Baltic International Yearbook of Cognition, Logic and Communication

Notwithstanding their technical virtuosity and growing presence in mainstream thinking, game theoretic logics have attracted a sceptical question: "Granted that logic can be done game theoretically, but what would justify the idea that this is the preferred way to do it?'' A recent suggestion is that at least part of the desired support might be found in the Greek dialectical writings. If so, perhaps we could say that those works possess a kind of foundational significance. The relation of being foundational for is interesting in its own right. In this paper, I explore its ancient applicability to relevant, paraconsistent and …

Games And Logic, Gabriel Sandu

Baltic International Yearbook of Cognition, Logic and Communication

The idea behind these games is to obtain an alternative characterization of logical notions cherished by logicians such as truth in a model, or provability (in a formal system). We offer a quick survey of Hintikka's evaluation games, which offer an alternative notion of truth in a model for first-order langauges. These are win-lose, extensive games of perfect information. We then consider a variation of these games, IF games, which are win-lose extensive games of imperfect information. Both games presuppose that the meaning of the basic vocabulary of the language is given. To give an account of the linguistic conventions …

Constructive Type Theory And The Dialogical Approach To Meaning, Shahid Rahman, Nicolas Clerbout

Baltic International Yearbook of Cognition, Logic and Communication

In its origins Dialogical logic constituted one part of a new movement called the Erlangen School or Erlangen Constructivism. Its goal was to provide a new start to a general theory of language and of science. According to the Erlangen-School, language is not just a fact that we discover, but a human cultural accomplishment whose construction reason can and should control. The resulting project of intentionally constructing a scientific language was called the Orthosprache-project. Unfortunately, the Orthosprache-project was not further developed and seemed to fade away. It is possible that one of the reasons for this fading away is that …

Ludics, Dialogue And Inferentialism, Alain Lecomte

Baltic International Yearbook of Cognition, Logic and Communication

In this paper, we try to show that Ludics, a (pre-)logical framework invented by J-Y. Girard, enables us to rethink some of the relationships between Philosophy, Semantics and Pragmatics. In particular, Ludics helps to shed light on the nature of dialogue and to articulate features of Brandom's inferentialism.

Ptarithmetic, Giorgi Japaridze

Baltic International Yearbook of Cognition, Logic and Communication

The present article introduces ptarithmetic (short for “polynomial time arithmetic”) — a formal number theory similar to the well known Peano arithmetic, but based on the recently born computability logic instead of classical logic. The formulas of ptarithmetic represent interactive computational problems rather than just true/false statements, and their “truth” is understood as existence of a polynomial time solution. The system of ptarithmetic elaborated in this article is shown to be sound and complete. Sound in the sense that every theorem T of the system represents an interactive number-theoretic computational problem with a polynomial time solution and, furthermore, such a …

Argumentation And Inference: A Unified Approach, Christophe Fouqueré, Myriam Quatrini

Baltic International Yearbook of Cognition, Logic and Communication

We propose in this paper to use Ludics as a unified framework for the analysis of dialogue and the reasoning system. Not only is Ludics a logical theory, but it may also be built by means of concepts of game theory. We first present the main concepts of Ludics. A design is an abstraction and a generalization of the concept of proof. Interaction between designs is equivalent to cut elimination or modus ponens in logical theories. It appears to be a natural means for representing dialogues and also for reasoning. A design is a set of sequences of alternate actions …

Antilogic, Benoît Castelnérac, Mathieu Marion

Baltic International Yearbook of Cognition, Logic and Communication

This paper is an interim report of joint work begun in (Castelnérac & Marion 2009) on dialectic from Parmenides to Aristotle. In the first part we present rules for dialectical games, understood as a specific form of antilogikê developed by philosophers, and explain some of the key concepts of these dialectical games in terms of ideas from game semantics. In the games we describe, for a thesis A asserted by the answerer, a questioner must elicit the answerer’s assent to further assertions B₁, B₂,…, B_n, which form a scoreboard from which the questioner seeks …

Trust And Risk In Games Of Partial Information, Robin Clark

Baltic International Yearbook of Cognition, Logic and Communication

Games of partial information have been used to explicate Gricean implicature; their solution concept has been murky, however. In this paper, I will develop a simple solution concept that can be used to solve games of partial information, depending on the players' mutual trust and tolerance for risk. In addition, I will develop an approach to non-conventional quantity implicatures that relies on "face" (Goffman (1967), Brown and Levinson (1987)).

Differentiation Of Solutions Of Second-Order Bvps With Integral Boundary Conditions, Alfredo Janson, Bibi Juman

Mathematics Colloquium Series

Janson’s and Juman’s research involves differentiating solutions of boundary value problems with integral conditions, as well as showing that the resulting functions solve an associated boundary value problem—called the variational equation—with new integral boundary values.

Twitter Influence And Cumulative Perceptions Of Extremist Support: A Case Study Of Geert Wilders, Gabrielle Blanquart, David M. Cook

Australian Counter Terrorism Conference

The advent of Social media has changed the manner in which perceptions about power and information can be influenced. Twitter is used as a fast‐paced vehicle to deliver short, succinct pieces of information, creating the perception of acceptance, popularity and authority. In the case of extremist groups, Twitter is one of several avenues to create the perception of endorsement of values that would otherwise gain less prominence through mainstream media. This study examines the use of Twitter in augmenting the status and reputation of anti‐Islam and anti‐immigration policy through the controlled release of social media information bursts. The paper demonstrates …

An Exploratory Study Of The Lived Experience Of Being An Intelligence Analyst, Sharon Moss, Jeff Corkill, Eyal Gringart

Australian Security and Intelligence Conference

Since the World Trade Centre terror attacks of 2001 the intelligence domain has grown rapidly. In keeping with this growth has been a significant increase of scholarly interest in the domain. The intelligence literature is dominated by research into the failures of the discipline, organisational structure and the politics of intelligence. The intelligence analyst is a critical component of the intelligence domain yet is remarkably absent from the intelligence literature. This research seeks to address that imbalance by examining the lived experience of the analyst operating in the law enforcement intelligence domain. To this end, interpretive phenomenology was employed to …

Breaking The Theft-Chain-Cycle: Property Marking As A Defensive Tool, William J. Bailey, David J. Brooks

Australian Security and Intelligence Conference

Any viable method of protecting property, dissuading the theft of property or ensuring the swift recovery of stolen property could be considered essential to general society. A number of crime preventive measures have been used in an attempt to achieve this objective. One such measure is property marking, employing various techniques to make property more readily identifiable. The study assesses technology to investigate effectiveness, both for dissuasion and for tracing once stolen. Mechanism for the disposal of stolen property forms an important part of this study, commencing with the mapping of the theft‐supply‐chain. Using a mixed methods approach, the research …

The Contemporary Australian Intelligence Domain - A Multi Dimension Examination, Alan Davies, Jeff Corkill

Australian Security and Intelligence Conference

In the complex and interconnected post 9/11 world the roles and functions of intelligence have evolved beyond being a secret capability of governments focused on national security needs. Intelligence has become recognised as a critical function necessary to support decision making across the full breadth of government and corporate activity. The concept of an intelligence community being purely national security centric and bounded by secrecy has become limited. Intelligence in support of decision making has become a far broader domain than previously believed. This paper investigates the degree of intelligence embedded‐ness across government agencies and departments at the federal, state …

Physical Security Barrier Selection: A Decision Support Analysis, Agnieszka Kiszelewska, Michael Coole

Australian Security and Intelligence Conference

Physical security controls aim to reduce risk through their ability to systematically deter, or detect, delay and respond against deviant acts within a risk context. Holistically the aim is to increase the difficulty and risks while reducing the rewards associated with an act of deviance as captured in Clarke’s Situational Crime Prevention (SCP) framework. The efficacious implementation of such controls commensurate with the risk context requires a considered undertaking referred as informed decision‐making. Informed decision‐making is effective when a suitable choice is made accordant with base rate data that achieves its defined objectives within costs versus benefits framework. The study …
