BabyTalk: An App for the NICU
(Virginia Tech, 2015-06-03)The purpose of this project is to improve parents experience in the NICU through design, technology, communication and storytelling. A series of shadowing appointments were conducted to gain empathy and a greater understanding ... -
Back annotation for conceptual structures
(Virginia Tech, 1995-07-08)The design of digital systems is getting more complex with rapid improvements in VLSI design which can accommodate many millions of gates in one integrated chip (IC). Additionally, the speed with which the design is completed ... -
Back to Back Active Power Filter for Multi-Generator Power Architecture with Reduced dc-link Capacitor
(Virginia Tech, 2020-01-30)Multi-pulse converters have been widely used for a multi-megawatt scale power generating system to comply with harmonic regulations. Among all types of multi-pulse converters, a 12-pulse converter is the most widely used ... -
Back-analysis methods for optimal tunnel design
(Virginia Tech, 2007-01-24)A fundamental element of the observational method in geotechnical engineering practice is the utilization of a carefully laid out performance monitoring system which provides rapid insight of critical behavioral trends of ... -
Backcountry campsite conditions assessed for limits of acceptable change planning in Shenandoah National Park
(Virginia Tech, 1994)Practicing science in a policy context demands careful attention. This research presents backcountry campsite conditions found in Shenandoah National Park during 1992. It fuels a policy process grounded in Limits-of-Acce ... -
Backcountry Trails Near Stream Corridors: An Ecological Approach To Design
(Virginia Tech, 1998-07-31)Traditional trails near backcountry stream corridors are often designed with disregard to their potential ecological impact. Ecological and trail related literature show that riparian landscapes are sensitive to recreation ... -
Background for finite element analysis and experimental testing of glued-laminated space beams
(Virginia Polytechnic Institute and State University, 1987)Two straight and one curved Southern Pine glued-laminated beams are subjected to bending, bending and compression, and biaxial bending. The beams are tested at service loads and only one beam is loaded to failure. The ... -
Background Noise Reduction in Wind Tunnels using Adaptive Noise Cancellation and Cepstral Echo Removal Techniques for Microphone Array Applications
(Virginia Tech, 2010-06-29)Two experiments were conducted to investigate Adaptive Noise Cancelling and Cepstrum echo removal post-processing techniques on acoustic data from a linear microphone array in an anechoic chamber. A point source speaker ... -
The background of state forest practice legislation and its impact upon forest land use and management
(Virginia Polytechnic Institute and State University, 1977)Five states were chosen for the study: New York, Massachusetts, California, Oregon and Washington. The author visited each of the five states and Washington, D.C. in 1976 to collect writings, published and informal, and ... -
Backpack Energy Harvester with Human Walking Model
(Virginia Tech, 2017-06-05)The objective of this thesis is to design, analyze, and fabricate an innovative backpack energy harvester for human walking. To model human walking with backpack energy harvester, a simple dual-mass model has been developed ... -
Backpressure Policies for Wireless ad hoc Networks
(Virginia Tech, 2010-03-16)Interference in ad hoc wireless networks causes the performance of traditional networking protocols to suffer. However, some user applications in ad hoc networks demand high throughput and low end-user delay. In the ... -
A backprogagation neutral network in an address block classifiction system
(Virginia Tech, 1991-05-15)The U.S. Postal Service (USPS) is investing heavily in research and development of automated mail handling systems. A major component in these systems is the use of Optical Character Recognition (OCR) to read the destination ... -

Bacteria-Enabled Autonomous Drug Delivery Systems: Design, Modeling, and Characterization of Transport and Sensing
(Virginia Tech, 2014-06-25)The lack of efficacy of existing chemotherapeutic treatments of solid tumors is partially attributed to the limited diffusion distance of therapeutics and the low selectivity of anti-cancer drugs with respect to cancerous ... -
Bacteria-Enabled Autonomous Drug Delivery Systems: Development, Characterization of Intratumoral Transport and Modeling
(Virginia Tech, 2017-08-17)Systemic chemotherapy is a major therapeutic approach for nearly all types and stages of cancer. Success of this treatment depends not only on the efficacy of the therapeutics but also on the transport of the drug to all ... -
Bacterial and chemical depression of pyrite in froth flotation of coal
(Virginia Polytechnic Institute and State University, 1978)Froth flotation was used to separate the pyrite sulfur and ash from pulverized coal samples of Illinois No. 6, Pittsburgh, and Middle Kittanning seams. In order to depress the coal pyrite in the flotation process, the coal ... -
Bacterial coagulation by a chlorinated solvent
(Virginia Tech, 1965-08-02)This investigation has led to the following conclusions: 1. Good removals of most bacterial species were observed. 2. Increased length of settling time increased the percent removal of pure cultures. 3. The solvent ... -
Bacterial extracellular polymers and flocculation of activated sludges
(Virginia Polytechnic Institute and State University, 1986)The extracellular polymers produced by bacteria play an important role in bacterial aggregation or bacterial flocculation in secondary waste treatment. The mechanisms responsible for this floc formation are thought to be ... -
Bacterial Kidney Disease and Its effect on the Salmonid Immune response
(Virginia Tech, 1997-11-04)Renibacterium salmoninarum, the etiological agent of bacterial kidney disease (BKD) of salmonid fish, is a pathogen of great concern among fisheries and the aquaculture industry worldwide. Previous investigations have ...
