Computational Fluid Dynamics Simulation of Green Water Around a Two-dimensional Platform
(2010-07-14)
An interface-preserving level set method is incorporated into the Reynolds-Averaged Navier-Stokes (RANS) numerical method to simulate the application of the green water phenomena around a platform and the breaking wave ...
A New I/O Scheduler for Solid State Devices
(2010-10-12)
Since the emergence of solid state devices onto the storage scene, improvements in capacity and price have brought them to the point where they are becoming a viable alternative to traditional magnetic storage for some ...
Experimental Analysis of the Effect of Vibrational Non-Equilibrium on the Decay of Grid-Generated Turbulence
(2010-10-12)
The technical feasibility of hypersonic flight (i.e., re-entry, hypersonic flight vehicles, cruise missiles, etc.) hinges on our ability to understand, predict, and control the transport of turbulence in the presence of ...
Effects of Parent Expectations and Involvement on the School Readiness of Children in Head Start
(2010-10-12)
There is an achievement gap occurring between ethnic minority children, mostly
from low-income homes, and European American children in the United States. The gap
between these children is present at school entry. Many ...
Adaptive Power Control for Single and Multiuser Opportunistic Systems
(2010-07-14)
In this dissertation, adaptive power control for single and multiuser opportunistic
systems is investigated. First, a new adaptive power-controlled diversity combining
scheme for single user systems is proposed, upon which ...
Tradeoff between Investments in Infrastructure and Forecasting when Facing Natural Disaster Risk
(2010-07-14)
Hurricane Katrina of 2005 was responsible for at least 81 billion dollars of property damage. In planning for such emergencies, society must decide whether to invest in the ability to evacuate more speedily or in improved ...
The Effects of Elite Decision Making
(2010-07-14)
Decision making is a central concept in the study of both politics and
organizations. Although much research has examined how individuals make decisions,
there has been substantially less work on the consequences of these ...
Experimental Study of Gas Turbine Blade Film Cooling and Heat Transfer
(2010-10-12)
Modern gas turbine engines require higher turbine-entry gas temperature to improve their
thermal efficiency and thereby their performance. A major accompanying concern is the heat-up
of the turbine components which are ...
PARTIALLY AVERAGED NAVIER-STOKES METHOD FOR TURBULENCE CLOSURES: CHARACTERIZATION OF FLUCTUATIONS AND EXTENSION TO WALL BOUNDED FLOWS
(2010-07-14)
The work presented in this dissertation concerns continued development, validation and verification of the partially averaged Navier-Stokes (PANS) method - a variable resolution closure model for turbulence. Linear eddy ...
Probabilistic Analysis of the Compressibility of Soils
(2010-07-14)
Geotechnical engineers are always faced with uncertainties and spatial variations in
material parameters. In this work, we propose to develop a framework able to account
for different types of uncertainties in a formal and ...
