Elliptic Problems In Domains With Piecewise Smooth Boundaries
Discusses general elliptic boundary value problems in domains with boundaries containing conical points and edges of different dimensions. The main topic is the solvability of such problems and the existence of asymptotic formulas for solutions near singularities. Applications to the mechanics of so
Superplasticity And Grain Boundaries In Ultrafine-grained Materials
Superplasticity is a state in which solid crystalline materials, such as some fine-grained metals, are deformed well beyond their usual breaking point. The phenomenon is of importance in processes such as superplastic forming which allows the manufacture of complex, high-quality components in such areas as aerospace and biomedical engineering.
Superplasticity and grain boundaries in ultrafine-grained materials discusses a number of problems associated with grain boundaries in metallic polycrystalline materials. The role of grain boundaries in processes such as grain boundary diffusion, relaxation and grain growth is investigated. The authors explore the formation and evolution of the microstructure, texture and ensembles of grain boundaries in materials produced by severe plastic deformation.
Written by two leading experts in the field, Superplasticity and grain boundaries in ultrafine-grained materials significantly advances our understanding of this important phenomenon and will be an important reference work for metallurgists and those involved in superplastic forming processes.

Boundaries And Landmarks
From the PREFACE.
This manual is intended to familiarize the surveyor with the different types of old boundaries that exist throughout the country. A great deal has been written on this general subject, especially in reference to the public lands of the West. Very little, however, is being done on the conveyances of the Eastern States, and it is my hope to furnish something which may prove useful to those who are likely to meet with cases of this sort. No attempt is made to describe how the lines should be measured; the intent is rather to furnish suggestions as to the method of locating the line to be measured - in short, finding it. It is far more important to have faulty measurements on the place where the line truly exists, than an accurate measurement where the line does not exist at all.
