Deceleration of a Rotating Disk in a Viscous Fluid
(AIP Publishing, 1979)A disk rotating in a viscous fluid decelerates with an angular velocity inversely proportional to time. It is found that the unsteady Navier–Stokes equations admit similarity solutions which depend on a nondimensional ... -
The Evolution of Longwave Solutions to the Nonlinear Schrödinger Equation
(AIP Publishing, 1984)In water of moderate depth, the behavior of small perturbations superimposed on Stokes wave trains is described by the nonlinear (cubic) Schrödinger equation. In the present study wave‐like solutions to this equation are ... -
Maintaining Spatial Orientation during Travel in an Immersive Virtual Environment
(MIT Press, 1999-12-01)An experiment is presented comparing the effects of various virtual travel techniques in an immersive virtual environment (VE) on the spatial orientation of users. The experiment was designed and implemented in the context ... -
The simple virtual environment library: An extensible framework for building VE applications
(MIT Press, 2000-04-01)As virtual environment (VE) technology becomes accessible to (and affordable for) an ever-widening audience of users, the demand for VE applications will increase. Tools that assist and facilitate the development of these ... -
Testbed evaluation of virtual environment interaction techniques
(MIT Press, 2001-02-01)As immersive virtual environment (VE) applications become more complex, it is clear that we need a firm understanding of the principles of VE interaction. In particular, designers need guidance in choosing three-dimensional ... -
An introduction to 3-d user interface design
(MIT Press, 2001-02-01)Three-dimensional user interface design is a critical component of any virtual environment (VE) application. In this paper, we present a broad overview of 3-D interaction and user interfaces. We discuss the effect of common ... -
A Survey of Usability Evaluation in Virtual Environments: Classification and Comparison of Methods
(MIT Press, 2002-08-01)Virtual environments (VEs) are a relatively new type of human-computer interface in which users perceive and act in a three-dimensional world. The designers of such systems cannot rely solely on design guidelines for ... -
DIVERSE: A Framework for Building Extensible and Reconfigurable Device-Independent Virtual Environments and Distributed Asynchronous Simulations
(MIT Press, 2003-02-01)We present DIVERSE, a highly modular collection of complimentary software packages designed to facilitate the creation of device-independent virtual environments and distributed asynchronous simulations. DIVERSE is free/open ... -
The Catchment Feature Model: A Device for Multimodal Fusion and a Bridge between Signal and Sense
(2004-09-18)The catchment feature model addresses two questions in the field of multimodal interaction: how we bridge video and audio processing with the realities of human multimodal communication, and how information from the different ... -
Induced nanoscale deformations in polymers using atomic force microscopy
(American Physical Society, 2004-11-19)An exact analytical solution, based on the method of images, is obtained for the description of the electric field between an atomic force microscope (AFM) tip and a thin dielectric polymer film (30 nm thick) spin coated ... -
Protecting the communication structure in sensor networks
(Hindawi Publishing Corporation, 2005)In the near future wireless sensor networks will be employed in a wide variety of applications establishing ubiquitous networks that will pervade society. The inherent vulnerability of these massively deployed networks to ... -
Technical note: Simulating chemical systems in Fortran90 and Matlab with the Kinetic PreProcessor KPP-2.1
(Copernicus Publications, 2006-01-01)This paper presents the new version 2.1 of the Kinetic PreProcessor (KPP). Taking a set of chemical reactions and their rate coefficients as input, KPP generates Fortran90, Fortran77, Matlab, or C code for the temporal ... -
The Effects of Text Drawing Styles, Background Textures, and Natural Lighting on Text Legibility in Outdoor Augmented Reality
(MIT Press, 2006-02-01)A challenge in presenting augmenting information in outdoor augmented reality (AR) settings lies in the broad range of uncontrollable environmental conditions that may be present, specifically large-scale fluctuations in ... -
Distinct patterns of SSR distribution in the Arabidopsis thaliana and rice genomes
(2006-02-21)Background Simple sequence repeats (SSRs) in DNA have been traditionally thought of as functionally unimportant and have been studied mainly as genetic markers. A recent handful of studies have shown, however, that SSRs ... -
The statistics of identifying differentially expressed genes in Expresso and TM4: a comparison
(2006-04-20)Background Analysis of DNA microarray data takes as input spot intensity measurements from scanner software and returns differential expression of genes between two conditions, together with a statistical significance ... -
XcisClique: analysis of regulatory bicliques
(2006-04-21)Background Modeling of cis-elements or regulatory motifs in promoter (upstream) regions of genes is a challenging computational problem. In this work, set of regulatory motifs simultaneously present in the promoters of a ... -
Automatic layout and visualization of biclusters
(2006-09-04)Background Biclustering has emerged as a powerful algorithmic tool for analyzing measurements of gene expression. A number of different methods have emerged for computing biclusters in gene expression data. Many of these ... -
A computational study of nucleosomal DNA flexibility
(CELL PRESS, 2006-12-01)Molecular dynamics simulations of the nucleosome core particle and its isolated DNA free in solution are reported. The simulations are based on the implicit solvent methodology and provide insights into the nature of ... -
Quantifying the major mechanisms of recent gene duplications in the human and mouse genomes: a novel strategy to estimate gene duplication rates
(2007-08-02)Background The rate of gene duplication is an important parameter in the study of evolution, but the influence of gene conversion and technical problems have confounded previous attempts to provide a satisfying estimate. ... -
Overlapping genes in the human and mouse genomes
(2008-04-14)Background Increasing evidence suggests that overlapping genes are much more common in eukaryotic genomes than previously thought. In this study we identified and characterized the overlapping genes in a set of 13,484 pairs ...
