Memetic algorithms for Spatial Partitioning problems
(ACM, )Spatial optimization problems (SOPs) are characterized by spatial relationships governing the decision variables, objectives, and/or constraint functions. In this article, we focus on a specific type of SOP called spatial ... -
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 ... -
Studying the Functional Genomics of Stress Responses in Loblolly Pine With the Expresso Microarray Experiment Management System
(Hindawi, 2002-01-01)Conception, design, and implementation of cDNA microarray experiments present avariety of bioinformatics challenges for biologists and computational scientists. The multiplestages of data acquisition and analysis have ... -
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 ... -
BSML: A Binding Schema Markup Language for Data Interchange in Problem Solving Environments
(Hindawi, 2003-01-01)We describe a binding schema markup language (BSML) for describing data interchange between scientific codes. Such a facility is an important constituent of scientific problem solving environments (PSEs). BSML is designed ... -
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 ... -
H++: a server for estimating pK(a)s and adding missing hydrogens to macromolecules
(2005-07-01)The structure and function of macromolecules depend critically on the ionization (protonation) states of their acidic and basic groups. A number of existing practical methods predict protonation equilibrium pK constants ... -
Learning When Less is More: “Bootstrapping” Undergraduate Programmers as Coordination Designers
(Computer Professionals for Social Responsibility, 2006)In this paper, we describe an undergraduate computer science class in the United States that we started with the intention of creating a participatory design experience to create distributed mobile collaborative technologies ... -
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 ... -
VMD: a community annotation database for oomycetes and microbial genomes
(2006-01-01)The VBI Microbial Database (VMD) is a database system designed to host a range of microbial genome sequences. At present, the database contains genome sequence and annotation data of two plant pathogens Phytophthora sojae ... -
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 ...
