Development of a Web-Based System for Water Quality Data Management and Visualization
(Virginia Tech, 2010-05-03)
With increasing urbanization and population growth, humankind faces multiple environmental challenges. Stresses on limited resources, especially water resources, are now greater than ever before. Watershed monitoring and ...
Fabrication of Three-Dimensionally Independent Microchannels Using a Single Mask Aimed at On-Chip Microprocessor Cooling
(Virginia Tech, 2007-11-28)
A novel fabrication process is presented which allows for three-dimensionally independent features to be etched in silicon using SF6 gas in a deep reactive ion etcher (DRIE) after a single etch step. The mechanism allowing ...
Virtual Clicker - A Tool for Classroom Interaction and Assessment
(Virginia Tech, 2011-12-02)
Actively engaging students in the classroom and promoting their interaction, both amongst themselves and with the instructor, is an important aspect to student learning. Research has demonstrated that student learning ...
The Development of a Social Anxiety Measure for Adolescents and Adults with ASD
(Virginia Tech, 2011-05-03)
Despite numerous studies documenting the high prevalence of social anxiety in children and adolescents with High Functioning Autism Spectrum Disorder (HFASD), there has been little empirical investigation into methods for ...
Salmonella Internalization From Contaminated Seeds or Irrigation Water in Greenhouse Tomatoes
(Virginia Tech, 2006-11-17)
Greenhouse grown tomato fruits and tissues were tested for the presence of Salmonella after the plants had been treated with Salmonella contaminated irrigation water or grown from contaminated seeds. Greenhouse grown tomato ...
Glutathione Dynamics in Arabidopsis Seed Development and Germination
(Virginia Tech, 2004-12-09)
Seed desiccation and germination have great potential for oxidative stress. Glutathione, one of the most abundant antioxidants in plant cells, is a crucial to the plant's defense mechanisms. To better understand glutathione's ...
Cold-start effects on performance and efficiency for vehicle fuel cell systems
(Virginia Tech, 2002-12-12)
In recent years government, academia and industry have been pursuing fuel cell technology as an alternative to current power generating technologies. The automotive industry has targeted fuel cell technology as a potential ...
The Design, Fabrication, and Modeling of a Piezoelectric Linear Motor
(Virginia Tech, 2001-12-19)
The focus of this research was to create a linear motor that could easily be packaged and still perform the same task of the current DC motor linear device. An incremental linear motor design was decided upon, for its ...
Impact Biomechanics of the Head and Neck in Football
(Virginia Tech, 2008-05-28)
The research presented in the thesis explores the biomechanics of the head and neck during impacts in football. The research related to the head is geared towards advancing the current understanding of the mechanisms of ...
Self-Healing of Thermoplastic Poly(Ethylene-co-Methacrylic Acid) Copolymers Following Projectile Puncture
(Virginia Tech, 2003-09-01)
Poly(ethylene-co-methacrylic acid) (EMAA) ionomer polymers carry great potential for use in a wide variety of unique applications due to their property of “self-healing” following projectile impact. Following puncture, ...
