On matrix-free pseudo-arclength continuation methods applied to a nonlocal partial differential equation in 1+1D with pseudo-spectral time-stepping
(2013-08-01)
In this thesis we examine a recent animal aggregation model which describes the
evolution of two populations of animals moving on a 1-dimensional spatial domain
differing only by the direction they travel. The equations ...
Investigation of dye-sensitized solar cell performance with single chirality semiconducting carbon nanotubes
(2015-03-01)
In this work, the performance, electrical transport, and optical properties of dye-sensitized solar cells (DSSCs) assembled with single-walled carbon nanotubes (SWNTs) of a single chirality in the photoanode were ...
Synthesis and in vitro assessment of chemically modified siRNAs targeting BCL2 that contain 2'-ribose and triazole-linked backbone modifications
(2015-08-01)
Short interfering RNAs (siRNAs) are biomolecules used for post-transcriptional gene regulation, and therefore hold promise as a future therapeutic by silencing gene expression of overexpressed deleterious genes. Chemically ...
Investigation of an alternative sulfonated silane in ceramic carbon electrodes for fuel cell applications
(2015-09-01)
The fabrication of an ideal electrode material for fuel cell application that can maintain an
optimal water content in both low and high relative humidity (RH) conditions has been studied
by many research groups. Previous ...
Prototype development and testing of active yaw moment control system using vehicle momentum wheel
(2015-01-01)
Vehicle stability is the essential key to evade accidents and drive without harm. It is in actual an extremely dynamic and active research topic nowadays. Active yaw moment control to improve vehicle’s handling and stability ...
Metal-free methodology for the preparation of ynones using potassium alkynyltrifluoroborates and its application to the synthesis of natural products
(2015-03-01)
A straightforward procedure for the preparation of ynones from potassium alkynyltrifluoroborate salts and acyl chlorides or anhydrides has been developed. The one-pot reaction is advantageous in that it does not require ...
RoboBUG: a game-based approach to learning debugging techniques
(2015-03-01)
Debugging is the systematic process of finding and fixing errors in a computer program, and it is considered a critical skill that should be acquired early in a programmer's career. As an alternative to traditional approaches ...
Brønsted acid-catalyzed reaction of alkynyltrifluoroborates with acetals and ketals
(2015-04-01)
The synthesis of small molecules is crucial in the pharmaceutical industry for producing drugs or biologically active compounds. Specifically, the formation of new carbon-carbon bonds is of great importance in synthetic ...
A matrix-free numerical bifurcation method applied to sheared annular electroconvection
(2015-08-01)
We investigate the flow transitions in sheared annular electroconvection using matrix-free numerical bifurcation methods. In particular, we study a model that simulates a liquid crystal film in the Smectic A phase suspended ...
Sex and seasonal variation in hippocampal volume and neurogenesis in the eastern chipmunk, Tamias striatus
(2015-07-01)
The hippocampus (HPC) is important in spatial memory and navigation and also exhibits adult neurogenesis. In wild-living species, HPC volume and neurogenesis have been found to differ between the sexes and vary seasonally ...
