Grain-Boundary Kinetics And Nonequilibrium Grain-Boundary Structure
… materials can be described as grain boundary (GB) networks; hence, GBs play major role in a wide-range of polycrystal properties. Control over GB kinetics provides effective means to tailor polycrystal properties through material processing. Understanding and prediction of GB kinetic …

Boundary data smoothness for solutions of nonlocal boundary value problems.
In this dissertation, we investigate boundary data smoothness for solutions of nonlocal boundary value problems over discrete and continuous domains. Essentially, we show that under certain conditions partial derivatives and differences exist, with respect to boundary conditions, for solutions of …

Thermal boundary resistance
The acoustic mismatch theory for the thermal boundary (Kapitza) resistance has peen modified so as to include the effect of phonon attenuation near the interface. The modified theory is in good agreement below 0.2 K with present measurements on metal-dielectric interfaces and with previous …

A Comparison of Two Boundary Methods For Biharmonic Boundary Value Problems
… purpose of this thesis is to solve biharmonic boundary value problems using two different boundary methods and compare their performances. The two boundary methods used are the method of fundamental solutions (MFS) and the method of approximate fundamental solutions (MAFS). The Delta-shaped …

Grain boundary network design
… and the network structure of the grain boundary ensemble have been experimentally observed to have a strong influence on many materials properties. This observation suggests that if we could control the types of grain boundaries present in a polycrystal and their spatial arrangement then …

Smallest Eigenvalues For A Fractional Boundary Value Problem With A Fractional Boundary Condition
… compare smallest eigenvalues for the fractional boundary value problems D_(0^+)^α u+λ_1 p(t)u=0 and $D_(0^+)^α u+λ_2 q(t)u=0,0< t< 1, satisfying the boundary conditions when n-1<α≤ n. First, we consider the case when 0<β<n-1, satisfying u^(i) (0)=0, i=0,1,…,n-2,D_(0^+)^β u(1)=0. Then, the case …

Boundary Value Problems for the Laplace Equation on Convex Domains with Analytic Boundary
In this thesis we study boundary value problems for the Laplace equation on do mains with smooth boundary. Central to our analysis is a relation, known as the global relation, that couples the boundary data for a given BVP. Previously, the global re lation has primarily been applied to elliptic …

The Impact and Role of Boundary Spanners and Boundary Objects in Global Project Networks
… individually and organizationally, can lead to boundary formation. Though past research has explored the boundary spanning capabilities within organizations, little is known about the roles and impacts of boundary spanning, both as individuals and as objects, in global project networks. I …

The Australia-Indonesia maritime boundary
The recent discovery of large oil and gas reserves in the Timor Sea1 has reemphasised the importance of establishing permanent boundaries between Australia and Indonesia in the area.

Transition in boundary layer flows
An experimental investigation of transition in boundary layer flows under the influence of various freestream conditions is described.<br/><br/>Velocity profiles are obtained automatically by means of a stepper-motor driven traverse mechanism which carries a hot wire probe connected to a constant …

Grain Boundary Structure in Alumina
Grain boundary microstructures in alumina ceramics are prone to show glassy phases, faceting, and some fraction of highly coincident twin-related boundaries. These separate phenomena and their inter- actions have been studied in six distinct materials of both commer- cial and experimental origin. …
