Experimental Studies To Address Strengths Of Limestone Cores, Sulfate Heave Problems In Limestone Cores And Tunnel Lining
(Civil & Environmental Engineering, 2007-08-23)
Sulfate induced heave is a common scenario in tunnels located on sedimentary rocks containing Pyrites. Pyrite oxidation produces Gypsum which is a major source of natural sulfates. DART NC -1B tunnel is located in Dallas, ...
Optimization Of The Tool Path In A Robotic Environment
(Mechanical Engineering, 2007-08-23)
The rising costs and demand coupled with shrinking energy generating resources has triggered the need for optimum use of energy resources, minimizing the overhead costs and maximizing the profits. Robots have been long ...
Interactive Animated Concept Map Generation - Using Dynamic Animations
(Computer Science & Engineering, 2007-08-23)
We present a visualization tool, which is useful for the illustration of educational concepts using interactive animated concept maps. This system serves as a presentation tool which provides a collection of multimedia ...
The Evolutionary History And Genomic Impact Of Mammalian Dna Transposons
(Biology, 2009-09-16)
Transposable elements (TEs) are mobile repetitive sequences that make up large fractions of mammalian genomes, including at least 45% of the human genome. Class 2, or DNA intermediate transposons, which make up approximately ...
A Novel Method For Major Harmonic Sources Identification In High Voltage Transmission Systems
(Electrical Engineering, 2010-03-03)
Due to the proliferation of high-voltage power electronics devices and nonlinear loads connected to power systems, the penetration of produced harmonics into power transmission networks to pollute power quality of power ...
Autonomous Abstraction Of Policies Based On Policy Homomorphism
(Computer Science & Engineering, 2009-09-16)
A life long learning agent performing in a complex and dynamic environment needs the ability to learn increasingly complex tasks over time. These agents over their lifetime have to learn new tasks, adapt the policies of ...
Effects Of Voltage Unbalance And System Armonics On The Performance Of Doubly Fed Induction Wind Generators
(Electrical Engineering, 2009-09-16)
Inherent difficulties in management of electric power in the presence of an increasing demand for more energy, non-conventional loads such as digital appliances, and non-sustainable imported fossil fuels has initiated a ...
On-chip Liquid-liquid Extraction And Separation Using Digital Microfluidics
(Mechanical Engineering, 2010-03-03)
In this thesis, on-chip liquid-liquid microextraction and separation using electrowetting on dielectric (EWOD) digital microfluidics was demonstrated by considering room temperature ionic liquid (RTIL) and DI water as two ...
