Fabrication and Characterization of Three Dimensional Electrospun Cortical Bone Scaffolds
(De Gruyter Open, 2014)
Bone is a composite tissue composed of an organic matrix, inorganic mineral matrix and water. Structurally, bone is organized into two distinct types: trabecular (or cancellous) and cortical (or compact) bone. Cortical ...
Flag Football Headgear STAR Protocol
This document details the protocol used to rate flag football headgear based on concussion risk according to the Virginia Tech Helmet Ratings.
Response to 'Comment on Linear inviscid wave propagation in a waveguide having a single boundary discontinuity: Part II: Application [J. Acoust. Soc. Am. 75, 356-362 (1984)]'
(Acoustical Society of America, 1986-10-01)
This paper addresses the comments of Dr. Bruggeman and Dr. van de Wetering. The source of the error present in the paper entitled "Linear inviscid wave propagation in a waveguide having a single boundary discontinuity: ...
Information theory and the finite-time behavior of the simulated annealing algorithm: Experimental results
This article presents an empirical approach that demonstrates a theoretical connection between (information theoretic) entropy measures and the finite-time performance of the simulated annealing algorithm. The methodology ...
Infographic: ACL injury reconstruction and recovery
(British Editorial Society of Bone and Joint Surgery, 2017)
Anterior cruciate ligament (ACL) injury is a considerable source of morbidity among athletes. Most ACL injuries (70%) are non-contact in nature, with women and patients aged between 15 and 30 years at particularly high ...
Dusty space plasma diagnosis using temporal behavior of polar mesospheric summer echoes during active modification
(Copernicus Publications, 2011)
The objective of this paper is to study the effect of different plasma and dust parameters on Polar Mesospheric Summer Echoes (PMSE) temporal behavior after turn-on and turn-off of radio wave heating and to use these ...
Parametric Computational Study on Butterfly-Shaped Hysteretic Dampers
Structural steel plates oriented to resist shear loading can be used as hysteretic dampers in seismic force resisting systems. Some steel plate hysteretic dampers have engineered cut-outs leaving shear links that exhibit ...
Note: Method for overcoming ductile failure in Munstedt-type extensional rheometers
(AIP Publishing, 2009-05-01)
The purpose of this note is to introduce an experimental technique to overcome ductile failure in uniaxial extensional flow and show a simple illustration of its effectiveness. Ductile failure prevents the rheological ...
Extended Viterbi Algorithm for Hidden Markov Process: A Transient/Steady Probabilities Approach
(Hikari Ltd., 2012)
In this paper an extended Viterbi algorithm is presented for first-order hidden Markov processes, with the help of a dummy combined state sequence. For this, the Markov switching’s transient probabilities and steady ...
Force-displacement relationship of a butterfly-shaped beams based on gene expression programming
Structural steel plates having engineered cut-outs to exhibit controlled yielding is recently proposed for desirable performance compared to conventional systems. Butterfly-shaped beams with hexagonal cut-outs inside of ...
