The human lens provides one-third of the ocular focussing power and is responsible for altering focus over a range of distances. This ability, termed accommodation, defines the process by which the lens alters shape to increase or decrease ocular refractive power; this is mediated by the ciliary muscle through the zonule. This ability decreases with age such that around the sixth decade of life...

In this paper, we discuss the ways that communication accommodation theory (CAT) can be a useful framework for understanding and diagnosing interactional issues in interpersonal and intergroup conflict situations. We argue that the theory’s construct of attuning strategies provides a multidimensional view of mutual adjustment, leading to insights relevant to successful versus unsuccessful confl...

The Marchitecture is a cognitive architecture for autonomous development of representations. The goals of The Marchitecture are domain independence, operating in the absence of knowledge engineering, learning an ontology of parameterized relational concepts, and elegance of design. Representation change comes about through a pair of primary mechanisms, which we term “assimilation” and “accommod...

Computational aspects of Van der Sandt’s binding and accommodation theory (BAT) for presupposition projection and anaphora resolution are presented and discussed in this article. BAT is reformulated to meet requirements for computational implementation, which include operations on discourse representation structures (renaming and merging), the representation of presuppositions (allowing for sel...

An exoteric geometric mechanics model of ocular accommodation is detailed to elucidate the main ideas of various ongoing modeling efforts. The present study derives solutions for the stretched state of the ocular lens as it might appear during accommodation by using simple geometric arguments and a volume constraint, rather than the more mathematically intensive theory of elasticity. Results sh...

The study of gas-solid accommodation at low pressure is of paramount importance to several areas of scientific research and industrial development. In Chemical Vapor Deposition (CVD) processes for instance, ONERA has quantified the accommodation for several diatomicsolid pairs and shown that, near or below 100 Pa, the gas can be substantially colder than the surface being grown, at a distance l...

1. SINGLE PHONON ACCOMMODATION COEFFICIENTS Introduction It is our present purpose to report some recent improvements in quantummechanical accommodation theory. -5 This study will be reported in detail later. The essence of the existing theories may be described as follows. An inert gas atom such as helium, described by an initial wave function '(r), undergoes a collision with a bound surface a...

We develop an analytical model for the thermal boundary conductance between a solid and a gas. By considering the thermal fluxes in the solid and the gas, we describe the transmission of energy across the solid/gas interface with diffuse mismatch theory. From the predicted thermal boundary conductances across solid/gas interfaces, the equilibrium thermal accommodation coefficient is determined ...

The condensational growth of submicrometer aerosol particles to climate relevant sizes is sensitive to their ability to accommodate vapor molecules, which is described by the mass accommodation coefficient. However, the underlying processes are not yet fully understood. We have simulated the mass accommodation and evaporation processes of water using molecular dynamics, and the results are comp...

This report presents a computer-animated model of the structures of accommodation based on new understanding of the anatomy of the zonular apparatus integrated with current understanding of the mechanism of accommodation. Analysis of this model suggests a new, consolidated theory of the mechanism of accommodation including a new theory of reciprocal zonular action. A three-dimensional animated ...
