Low Frequency Oscillations in A Plasma with Spatially Variable Field-Aligned Flow
(AIP Publishing, 2002-05-01)
The effects of a transverse gradient in the plasma flow velocity parallel to the ambient magnetic field are analyzed. A transverse velocity gradient in the parallel ion flow, even in small magnitude, can increase the ...
Autofocusing in optical scanning holography
(Optical Society of America, 2009-12-01)
We present autofocusing in optical scanning holography (OSH) with experimental results. We first record the complex hologram of an object using OSH and then create the Fresnel zone plate (FZP) that codes the object constant ...
Exact solution for four-order acousto-optic Bragg diffraction with arbitrary initial conditions
(Optical Society of America, 2009-03-01)
An exact solution to the four-order acousto-optic (AO) Bragg diffraction problem with arbitrary initial conditions compatible with exact Bragg angle incident light is developed. The solution, obtained by solving a 4th-order ...
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 ...
Fracture Resilience and Redundancy of Built-up Steel Girders
(American Institute of Steel Construction, 2016-04-15)
Internal member redundancy provides built-up steel girders with the ability to resist total member failure in the event an individual component fails. Anecdotal evidence of in- service performance has historically shown ...
Towards a Better Estimation of Inspection Intervals for Cracking Steel Railroad Bridges
(American Railway Engineering and Maintenance-of-Way Association, 2015-10-05)
In order to best prioritize limited funds for railroad bridge capital and maintenance, it is important for the bridge engineer to have an accurate estimate of service life for existing steel bridges. In the context of the ...
Extending the 5S Digital Library Framework: From a Minimal DL Towards a DL Reference Model
In this paper, we describe ongoing research in three DL projects that build upon a common foundation: the 5S DL framework. In each project, we extend the 5S framework to provide specifications for a particular type of DL ...
Open Archives: Communities, Interoperability, and Services
Proceedings of the SIGIR 2001 OAI Workshop. This workshop includes discussions about metadata harvesting and OAI protocol features, requests, and responses.
Two Approaches to Enhance the Education for ETDs: Developing Educational Modules and Migrating the ETD Guide into a Community Wiki
Two efforts have been made by the Digital Library (DL) Curriculum Development Project Group (http://curric.dlib.vt.edu) to help the ETD community. Our first activity is the preparation of multiple educational modules, which ...
Improving Education and Understanding of NDLTD
To understand ETDs, what NDLTD is, how it works, and the benefits of NDLTD, it is necessary to educate those involved, such as students who will create and submit their ETDs, as well as the library staff members who will ...
