C-NORTA: A Rejection Procedure for Sampling from the Tail of Bivariate NORTA Distributions
We propose C-NORTA, an exact algorithm to generate random variates from the tail of a bivariate NORTA random vector. (A NORTA random vector is specified by a pair of marginals and a rank or product-moment correlation, and ...
Definitions of Interdisciplinary Research: Toward Graduate-Level Interdisciplinary Learning Outcomes
(Johns Hopkins Univ Press, 2010)
Combining the interdisciplinary studies (primarily humanities) literature with the content analysis of 129 successful National Science Foundation proposals written predominantly by science and engineering faculty members, ...

Flexural Capacity Prediction Method for an Open Web Joist Laterally Braced by a Standing Seam Roof System
(Virginia Polytechnic Institute and State University, 2012-04-01)
A new strength prediction approach is presented for open web joists partially braced by a standing seam roof. The approach employs the existing AISC column curve to calculate top chord flexural buckling capacity using the ...
Fitting the Ph-t/M-t/s/c Time-Dependent Departure Process for Use in Tandem Queueing Networks
This paper considers time-dependent Ph-t/M-t/s/c queueing nodes and small tandem networks of such nodes. We examine characteristics of the departure processes from a multiserver queueing node; in particular, we focus on ...
Optimal Sampling Laws for Stochastically Constrained Simulation Optimization on Finite Sets
Consider the context of selecting an optimal system from among a finite set of competing systems, based on a "stochastic" objective function and subject to multiple "stochastic" constraints. In this context, we characterize ...
An Algorithm for Fast Generation of Bivariate Poisson Random Vectors
We present the "trivariate reduction extension" (TREx)-an exact algorithm for the fast generation of bivariate Poisson random vectors. Like the normal-to-anything (NORTA) procedure, TREx has two phases: a preprocessing ...
Dynamic Optimizations of Irregular Applications on Many-core Architectures (CS Seminar Lecture Series)
Abstract: Enhancing the match between software executions and hardware features is key to computing efficiency in terms of both performance and energy consumption. The match is constantly complicated by emerging architecture ...
Using a Type-centric, Multi-dimensional Event Dispatch Strategy to Simplify Android Programming (CS Seminar Lecture Series)
Abstract: The Android Platform is a popular choice for mobile application developers because of its large user base and the open-source development tools that are available. Further, because Android applications are built ...
Computational Challenges in Space Research (CS Seminar Lecture Series)
The Center for Space Science and Engineering Research (Space@VT) in the College of Engineering is a relatively new center having been initiated in summer 2007.At the present time Space@VT comprises twelve Faculty in the ...
