Planarity has been successfully exploited to design faster and more accurate approximation algorithms for many graph optimization problems. The celebrated theorem of Kuratowski completely characterizes planar graphs as those excluding K_5 and K_{3,3} as minors. Kuratowski's theorem allows one to generalize planar graphs to H-minor-free graphs: those that exclude a...
The study of differentiation of integrals has led to the study of maximal functions. In the development of harmonic analysis, the most powerful result connected with Lebesgue's theorem was that of the Hardy-Littlewood Maximal Theorem. This maximal theorem implies Lebesgue's theorem, and the maximal function and its variants have played...
The major purpose of this study was to assess the effectiveness of
interactive video in the teaching/learning process. More specifically,
a comparison was made of the relative effectiveness of interactive
video and linear video as delivery modes in the acquisition of basic
photography skills in an independent learning environment at...
Incremental ADCs (IADCs) have many advantages for low-frequency high-accuracy data conversion—they are easy to multiplex between channels, need simpler digital decimation filter, and allow extended counting with a Nyquist-rate ADC. A single-loop incremental ADC was designed and fabricated in 90 nm for a biosensor interface circuit. It incorporates one integrator,...
Homeodomain transcription factors control developmental processes. They pattern body formation, specify cell lineages and switch the onset of gene regulatory cascades. Pitx2, a bicoid-related homeodomain transcription factor, is asymmetrically expressed in the left lateral plate mesoderm and mesoderm-derived tissues. Pitx2 null mice are characterized by failure of body wall closure,...
The various solution-based processes, spin coating, inkjet printing, microreactor assisted nanoparticle deposition (MANDTM) and spin-successive ionic layer absorption and reaction (Spin-SILAR) were used to demonstrate thin film electronics and anti-reflective coatings. Several aspects of thin film transistors (TFTs) were tested including a range of temperatures, annealing atmosphere, and deposition methods....
The critical contribution of this dissertation is to provide a better
understanding of the fundamental Chemical Bath Deposition (CBD) growth
kinetic and mechanism for the well known II-VI semiconductor CdS using the
newly developed continuous flow microreactor. This continuous flow microreactor
provides the temporal resolution to control the homogeneous reaction...
CuInGaSe₂ (CIGS), a promising thin film solar cell material, has gained lots of
attention in decades due to its high energy conversion efficiency and potential lower
manufacture cost over conventional Si solar cells. As a cheaper processing method
compared to vacuum-based techniques, solution-based deposition has been
successfully applied to fabricate...
There is an emerging interest in developing wearable electronics as a platform, which
provides the flexibility of a wearable while maintaining its promising functionality as smart textiles. Metal-halide semiconductors are attractive materials with tunable optical and electrical properties. Researchers have widely studied and applied it for advanced
photonics and optoelectronic...
