Abnormal Grain Growth of Tungsten Carbide in Small Amount of Cobalt: Mechanism and Application
… CEMENTED WC WITH 0.2~0.9WT% COBALT. MICROSTRUCTURE EXAMINATIONS SHOWED GRAIN BOUNDARIES PARALLEL TO (0001) PLANES AND AGG WAS EXPLAINED BY GRAIN BOUNDARY RE-ENTRANT EDGE (GBRE) ASSISTED 2-D NUCLEATION PROCESS. GRAIN COALESCENCE IN LIQUID COBALT WAS ASSUMED TO BE THE SOURCE FOR THE GRAIN …

Teacher Performance in the Nongraded Elementary Schools of Central Washington
… study is to determine the extent to which a non graded structure in the elementary schools "permits teachers to operate more freely with respect to instructional decisions."</p>

Multiscale Structures and Mechanics of Biomineralized Lattices in Hexactinellid sponges and Echinoderms
… However, the quantitative explorations of the structure-mechanics relationships in multiscale of biomineralized lattices remain insufficient and hence hinder the leverage of the functional benefits to design architected cellular materials. In this dissertation, I selected two groups of marine …

Study of Thin GaN/InGaN/GaN double graded structures for Future photovoltaic application
… in the material is significant. In this work, graded composition In_x Ga_(1-x) N (44 nm ramping up followed by 44 nm ramping down) were grown on GaN/sapphire template. The growth was done at different indium compositions (low to high) in plasma-assisted MBE. Additionally, optical and structural …

The Asymptotic Cone of Teichmuller Space: Thickness and Divergence
… of the canonical finest pieces in the tree-graded structure of the asymptotic cone of Teichmüller space along the same lines as similar characterizations for right angled Artin groups by Behrstock-Charney and for mapping class groups by Behrstock-Kleiner-Minsky-Mosher. As a corollary of the …

High accuracy computational methods for the semiclassical Schrödinger equation
… operators. Combined with the $\mathbb{Z}_2$-graded structure of this Lie algebra, the symmetry results in skew-Hermiticity of the exponents for Zassenhaus-style splittings, resulting in unitary evolution and numerical stability. The properties of commutator simplification and height reduction …

A description and evaluation of a continuous progress program for introductory algebra
… and practitioners favour abandoning the graded structure and developing instead the type of program which permits learning to be conducted on some form of continuum for each individual learner. The purpose of this project was to develop a continuous progress program in introductory …

Bulk Ceramic-Based Biologically Inspired Composites: Design, Fabrication and Testing
… systems. This dissertation aims to reveal the structure-property relationships of these structural motifs and the trade-offs to the mechanical robustness due growth-related constraints. With the help of stereolithographic additive manufacturing technique and centrifugal infiltration, we propose …
