(Virginia Tech, 2013-01-21)Distributed sensing is highly desirable in a wide range of civil, industrial and military applications. The current technologies for distributed sensing are mainly based on the detection of optical signals resulted from ...
-
(Virginia Tech, 2004-05-05)There have been several design models for single plate shear connections in the past 20 years. The current design model states that the bolt shear rupture strength of a connection is a function of the number of bolts and ...
-
(Virginia Tech, 2013-04-25)The quasi-geostrophic equations (QGE) are usually discretized in space by the finite difference method. The finite element (FE) method, however, offers several advantages over the finite difference method, such as the easy ...

FOUR-MONTH-OLDS DO NOT PREFER BUT CAN DISCRIMINATE INFANT DIRECTED AND ADULT DIRECTED PITCH CONTOURS(Virginia Tech, 2003-02-25)The purpose of the present study was to investigate the role of pitch contours in directing infant attention to adult speech. Several studies have shown that infants from a few days old to 9 months of age prefer ...
-
(Virginia Tech, 2011-08-22)The usefulness of watershed hydrological process models is considerably increased when they can be extrapolated across spatial and temporal scales. This scale transfer problem, meaning the description and prediction of ...
-
(Virginia Tech, 2003-12-08)In the late 1980s and early 1990s few transportation agencies around the world considered performance-based specifications as an alternative to improve the efficiency of the services provided to the public. These initiatives ...
-
(Virginia Tech, 1998-06-25)The goal of planning is to use knowledge to determine action. Planning theory has focused specifically on how the process of achieving this occurs. Two dominant theories prevail: rational comprehensive and communicative ...

(Virginia Tech, 2003-04-04)A functional water-conducting system, the tracheary elements of the xylem, is required to sustain plant growth and development. Tracheary element formation is dependent on many biological processes terminated by programmed ...
-
(Virginia Tech, 2004-06-09)The Internet has a loosely hierarchical structure. At the top of the hierarchy are the backbones, also called Internet Access Providers (hereafter IAPs). The second layer of the hierarchy is comprised of Internet Service ...
-
(Virginia Tech, 2004-02-05)Abstract Immigration policy and tradition dovetail in their impact on the social organization of immigrant communities, linking the material and non-material aspects of gender. I focus on Asian Indian Patels, who dominate ...
-
(Virginia Tech, 2003-09-17)This dissertation examines aspects of both the consumer (the "give") and the server (the "take") sides of restaurant tipping. On the consumer side, I address both why, and how much, people tip in restaurants. I also ...
-
(Virginia Tech, 2003-10-31)This research examined the validity of the 2-factor (e.g., Button, Mathieu, and Zajac, 1996) and 3-factor (e.g., VandeWalle, 1997) models of goal orientation. These models differ in specifying the dimensionality, measurement, ...
-
(Virginia Tech, 2004-04-21)Research has indicated that the frontal and temporal lobes are involved in the mediation of heart rate and blood pressure. However, whereas these regions of the brain have been identified in the mediation of heart rate ...
-
(Virginia Tech, 2002-05-08)New heating techniques are required to better control heat transfer between heating tools and a composite towpreg in the automated fiber placement process. This dissertation suggests new heating techniques with liquid and ...
-
Heat Transfer in Stationary and Rotating Coolant Channels Using a Transient Liquid Crystal Technique(Virginia Tech, 2012-11-27)Heat transfer inside rotating coolant channels have a significant impact in design of gas turbine airfoils and other rotating components such as generator windings. The effects of the Coriolis acceleration and centrifugal ...
-
(Virginia Tech, 2002-11-22)This dissertation takes as its starting point some curious historical parallels in research on the heritability of alcoholism from opposite ends of the 20th century, and the underlying continuity in assumptions implicated ...
-
(Virginia Tech, 2004-07-26)A novel noise control system is developed using adaptable tuned vibration absorbers (ATVA) to interact with a vibrating host structure in such a way as to reduce radiated acoustic energy. ATVA's are single-degree-of-freedom ...
-
(Virginia Tech, 2013-05-08)Despite the recent advances in systems and network security, attacks on large enterprise networks consistently impose serious challenges to maintaining data privacy and software service integrity. We identify two main ...
-
(Virginia Tech, 2004-04-22)It is perceived that Moore's Law will prevail at least for the next decade with the continuous advancement of processing technologies for integrated circuits. According to Intel's roadmap, over one billion transistors will ...
