Large displacement FEM modelling of the cone penetration test (CPT) in normally consolidated sand
(John Wiley & Sons, Ltd., 2003-06)
A new finite element model based on a large strain formulation has been developed to study cone penetration in normally consolidated sand. An auto-adaptive remeshing technique was utilized for handling the very large ...
Controlling Electromagnetic Surface Waves with Scalar and Tensor Impedance Surfaces.
(2013)
The propagation characteristics of electromagnetic waves on various isotropic (scalar) impedance surfaces have been studied for some time, in order to control surface waves and leaky-wave radiation. One and two dimensional ...
Synthetic Strategies and Parameters Involved in the Synthesis of Oligodeoxyribonucleotides According to the Phosphoramidite Method
(Wiley Periodicals, Inc.Plenum, 2000-02)
The phosphoramidite approach has had a major impact on the synthesis of oligonucleotides. This unit describes parameters that affect the performance of this method for preparing oligodeoxyribonucleotides, as well as a ...
Picosecond X-ray diffraction studies of laser-excited acoustic phonons in InSb
(Springer-Verlag, 2002-10)
We have employed time-resolved X-ray diffraction with picosecond temporal resolution to measure the time-dependent rocking curves of laser-irradiated asymmetrically cut single InSb crystals. Coherent acoustic phonons were ...
Development of a Time-Resolved Laser-Induced Fluorescence Technique for Nonperiodic Oscillations
(2016)
Time-resolved measurements of ion dynamics could be key to understanding the physics of instabilities, electron transport, and erosion in Hall thrusters. Traditional measurements of the ion velocity distribution in Hall ...
Finite Element Modeling of Longitudinal Metastructures for Passive Vibration Suppression
(American Institute of Aeronautics and Astronautics, 2016-01-01)
Novel Foot Orthosis
(2006-12)
The objective of this design project is to implement a device capable of resting the posterior Thetibialis tendon (for less advanced stages of PTT), or (for more advanced cases) to perform the functions of the tendon by ...
Micro-mechanical deformation mechanisms in the fracture of hybrid-particulate composites based on glass beads, rubber and epoxies
(Wiley Subscription Services, Inc., A Wiley Company, 2000-12)
Two tougheners, glass beads and carboxyl terminated butadiene acrylonitrile copolymer (CTBN), are used to toughen and stiffen an epoxy thermoset. Rubber-encapsulated glass beads are used and the hybrid particulate composites ...
Nanostructured Semiconductors for Thermoelectric Energy Conversion: Synthesis and Transport Properties.
(2013)
Half-Heusler (HH) alloys are among the most popular material systems for high temperature thermoelectric energy conversion. Approaches to increase the thermoelectric figure of merit (ZT) of HH range from (1) chemical ...
