(Virginia Tech, 2013-01-11)Abstract<br /><br />Looking for ways that dance could be used as a tool for health promotion, I sought to explore dance choreography and performance as an alternative medium for educating and increasing awareness about ...
-
(Virginia Tech, 2003-04-15)This study addresses the paralegal occupation and how it is defined within the context of licensure, control, and regulation in the United States. Drawing upon social theories of the emergence of professions and the concept ...
-
(Virginia Tech, 2003-04-16)This research discusses the mechanical characteristics of laminated piezoelectric actuators that are manufactured at an elevated temperature, to cure the adhesive bonding the layers together, or to cure the layers made of ...
-
(Virginia Tech, 2013-05-13)The present study used a case study approach to gather information about learning object usage from multiple instructional design contexts. The study examined three case contexts: A non-profit organization, a corporate ...
-
(Virginia Tech, 2012-12-17)This research has a small portion focused on interior serpentine channels, with the primary focus on improving the effectiveness of the film cooling technique through the use of a new approach to film cooling. This new ...
-
(Virginia Tech, 2012-12-07)Accurate measurement of skin friction in complex flows is important for: documentation and monitoring of fluid system performance, input information for flow control, development of turbulence models and CFD validation. ...
-
(Virginia Tech, 2013-04-23)In this dissertation research we aim to design and validate intrusion detection system (IDS) protocols for a cyber physical system (CPS) comprising sensors, actuators, control units, and physical objects for controlling ...
-
(Virginia Tech, 2013-02-01)Cardiovascular disease is currently the leading cause of death in the U.S. that frequently requires bypass surgery using vascular grafts for treatment. Current limitations with fully synthetic grafts have led researchers ...
-
(Virginia Tech, 2004-02-06)Power amplifiers (PA) are typically the most power-consuming building blocks of RF transceivers. Therefore, the design of a high-efficiency radio frequency power amplifier is the most obvious solution to overcoming the ...
-
(Virginia Tech, 2004-09-13)The driving force of the tourism industry is represented by the attractions at destination. Travelers have no reason to visit destinations that have nothing to offer. Tourism research has demonstrated that attraction studies ...
-
(Virginia Tech, 2003-11-20)As a strategy to conserve tropical rainforests of the East Usambara block of the Eastern Arc Mountains, Tanzania, I developed a set of models that can identify above-average tree species richness areas within the humid ...
-
(Virginia Tech, 2013-03-15)Falls are the leading cause of injuries among older adults (>65) and frequently result in reduced mobility, loss of independence, decreased quality of life, injury, and death. Extensive research has been conducted regarding ...
-
(Virginia Tech, 2013-05-14)Though the benefits of physical activity are numerous and well-known, very few adolescents are meeting physical activity recommendations. Moreover, past research shows that physical activity declines with increasing age ...
-
Developing Guidelines for Collaborative Spaces Supporting Interdisciplinary Engineering Design Teams(Virginia Tech, 2013-04-25)Communication deficiencies within interdisciplinary teams are known to reduce the effectiveness of those teams by causing erroneous behaviors (Alvarez & Coiera, 2006; Reader, Flin, & Cuthbertson, 2007). Also, many design ...
-
(Virginia Tech, 2004-07-07)Evaluation is the key to effective interface design. It becomes even more important when the interfaces are for cutting edge technology, in application areas that are new and with little prior design knowledge. Knowing how ...
-
(Virginia Tech, 2004-03-22)This study tested a mediated-moderator model that was developed to explore whether age of entry into a Head Start Program moderated the relationship between maternal depressive symptomology and child cognitive and social ...
-
(Virginia Tech, 2012-12-06)Work-related musculoskeletal disorders (WSMDs) are an important health concern in the workplace. Accurately quantifying the level of physical exposures (i.e., kinematics and kinetics) is essential for risk assessments, ...
-
(Virginia Tech, 2003-05-01)A steady-state computational model for a proton exchange membrane fuel cell (PEMFC) is presented. The model accounts for species transport, electrochemical kinetics, energy transport, current distribution, water uptake ...
-
(Virginia Tech, 2013-04-23)Previous authors have developed many different types of water pipe condition and failure models using the various methodologies available. Contrary, current utilities are struggling to maintain their current water ...
