Routing from a single source node to multiple destination nodes using node disjoint paths (NDP) has many important applications in parallel systems. For example, if a source node wants to send distinct messages to distinct destination nodes, then the one-to-many NDP routing is useful.
Unlike parallel systems with shared-memory, each...
Two new medium access protocols for ring type local area networks,
CTR (Concurrent Token Ring) protocol and DRUID (Destination Removal
withoUt Intermediate node Delay) ring protocol, are proposed, designed and
analyzed. A destination partial removal technique is designed and used in
these two protocols to support concurrent message transmission and...
This dissertation investigates the use of a hardware mechanism called Eager Data Transfer (EDT) for achieving the reduction of communication latency for user-level network protocol. To reach the goal, the dissertation addresses the following research issues. First, the development of a communication system performance evaluation tool called Linux/SimOS is presented....
This dissertation consists of two essays that address behavioral economics issues.
In first chapter we analyze the effects of psychological pressure on performance using National Basketball Association (NBA) free throw data from the 2002-2003 through 2009-2010 seasons. We find evidence that players choke under pressure – they shoot on average...
During the interstate expansion of the 1950s, many conventionally reinforced concrete
deck girder bridges were built throughout the country. These now vintage bridges
commonly exhibit diagonal cracking and rate inadequately for shear, thus they are
candidates for shear strengthening to extend their useful life. Near-surface mounted
(NSM) retrofitting is a...
The degenerate nature of the metric on null hypersurfaces creates many difficulties
when attempting to define a covariant derivative on null submanifolds. This dissertation
investigates these challenges and provides a technique for defining a connection on null
hypersurfaces in some cases. Recent approaches using decomposition to define a covariant
derivative...
Originally used as a method to densify loose soils, controlled blasting has expanded its applicability to geotechnical engineering by becoming a research tool to physically generate liquefaction for full-scale in-situ tests, ranging from seismic performance of deep foundations to evaluating ground improvement techniques. Current methods used to design the blasting...
This ethnography looks at the processes a rural Oregon community is undergoing as some members attempt to re-animate the community by creating a community center after the loss of its school and market, two vital services that provided venues for social interaction and engagement.
The methodology for this research includes...
This collection of poetry explores faith and isolation while questioning the ability of language to adequately express subjective experience. Gustie has provided a deeply contemplative, though rarely completely serious, romp through the lives of others who, ultimately, are reflections of the self. The three sections of the collection establish a...
Full dynamic control of physically simulated characters is the holy grail of video
games and other interactive applications. Recent advances in the field have
presented controllers that can handle the balance and fall response after a
collision. This thesis addresses the development of a controller that handles the
response before...
