Introduction to Distributed Self-Stabilizing Algorithms

Abstract: This book aims at being a comprehensive and pedagogical introduction to the concept of self-stabilization, introduced by Edsger Wybe Dijkstra in 1973. Self-stabilization characterizes the ...

Average and Local Structure of (1−x)BaTiO3−xLaYO3 (0≤x≤0.50) Ceramics

Abstract: Dense ceramics of (1−x)BaTiO3−xLaYO3 (LBTY) (0≤x≤0.50) have been fabricated by the conventional solid-state route. Phase purity and crystal structure of LBTY ceramics were investigated using a combination of X-ray diffraction (XRD), electron diffraction (ED), and Raman spectroscopy. XRD analysis shows the tetragonal distortion of undoped (x=0) BaTiO3 (space group P4mm) decreases with increasing x, reaching an average cubic symmetry (space group ) at x=0.05. For x>0.05, the lattice parameter a increases almost linearly up to x=0.40, above which a secondary phase isostructural with LaYO3 precipitates. ED patterns along [110]p for 0.30≤x≤0.40 exhibit superlattice reflections at 1/2 (hkl) positions, indicating a doubling of the unit cell, which may arise from either octahedral tilting and/or chemical 1:1 B-site ordering within nanoclusters. Existence of nanodomains was revealed by dark-field transmission electron microscopy (TEM). Raman spectroscopy reveals nanoclustering to occur readily at low substitution levels and to increase progressively toward a nanoscale phase separation-like phenomenon, which precedes the precipitation of individual crystals of an LaYO3-based solid solution. Three distinctive subgrain microstructures are revealed by conventional TEM imaging. x=0 exhibits ferroelectric microdomains which completely transverse the grains, whereas for x=0.025 and 0.05, ferroelectric microdomains coexist with nanodomains. Other structural features such as core-shell-type substructures, {111} twins and dislocations are also observed in some grains. For x>0.10, only nanodomains are observed.

Adaptive Alternate Analog Test

Abstract: Adaptive test is a promising approach for test cost reduction. This article presents an adaptive test scheme for analog circuits that capitalizes on alternate test to achieve a low cost for the majority of fabricated devices. The small fraction of devices for which the alternate test decision may be prone to error are identified and further action is taken.
