UPS-indel: a Universal Positioning System for Indels
(Nature, 2017-10-26)
Storing biologically equivalent indels as distinct entries in databases causes data redundancy, and misleads downstream analysis. It is thus desirable to have a unified system for identifying and representing equivalent ...
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 ...
ADML: Aircraft Design Markup Language for Multidisciplinary Aircraft Design and Analysis
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2013-12-31), TR-13-07
The process of conceptual aircraft design has advanced tremendously in the past few decades due to rapidly developing computer technology. Today’s modern aerospace systems exhibit strong, interdisciplinary coupling and ...
Probability-one Homotopy Maps for Constrained Clustering Problems
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2013-12-31), TR-13-09
Many algorithms for constrained clustering have been developed in the literature that aim to balance vector quantization requirements of cluster prototypes against the discrete satisfaction requirements of constraint ...
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 ...
Multiobjective Optimization Using an Adaptive Weighting Scheme
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2013-12-31), TR-13-08
A new Pareto front approximation method is proposed for multiobjective optimization problems with bound constraints. The method employs a hybrid optimization approach using two derivative free direct search techniques, and ...
Propagation of spinning acoustic modes in partially choked converging ducts
(Acoustical Society of America, 1982-04-01)
A computer model based on the wave-envelope technique is used to study the propagation of spinning acoustic modes in converging hard-walled and lined circular ducts carrying near sonic mean flows. The results show that ...
Continuous Homotopies for the Linear Complementarity Problem
(Department of Computer Science, Virginia Polytechnic Institute & State University, 1987-05-01), TR-87-38
There are various formulations of the linear complementarity problem as a Kakutani fixed point problem, a constrained optimization, or a nonlinear system of equations. These formulations have remained a curiosity since not ...
Pointwise Bias Error Bounds for Response Surface Approximations and Min-Max Bias Design
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2004), TR-04-03
Two approaches addressing response surface approximation errors due to model inadequacy (bias error) are presented, and a design of experiments minimizing the maximal bias error is proposed. Both approaches assume that the ...
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 ...
