Introduction to the Special Section Unsettling Korean Migration: Multiple Trajectories and Experiences

Introduction to this special section: Imaging migration

M imaging methods are slowly but surely trending toward the solution of an inverse problem, not only for the velocity-estimation phase but also for the migration step. The general direction is toward the conventional imaging twostep process of velocity estimation followed by migration being superseded by the single full-waveform inversion (FWI) process. However, today, advanced imaging workflow...

Human Ecology Review, Vol. 16, No. 1, 2009 © Society for Human Ecology The collection of articles for this special section is primarily the result of a symposium organized by Dr. Tom Dietz that took place at the XIV International Conference of the Society for Human Ecology. The symposium as well as this collection of papers represents a unique cross-section of scholars at various stages in thei...

Introduction to the Special Section

ystem identification refers broadly to the problem of developing empirical mathematical models of systems based on excitation and response measurements. Such models are useful for enhancing physical understanding; analyzing system properties; and performing simulation, prediction, filtering, state estimation, monitoring, and fault diagnosis as well as control. Practical interest in system ident...

Introduction to the Special Section

I F we consider Zuse’s Plankalktil the first programming language, research on computer languages is about half a century old now. During this period, languages have always been in the mainstream of computer science research. The focus of the research has perhaps shifted somewhat from efficiency (1950s) to expressivity (196Os), portability (197Os), and handling complexity (198Os), but the inter...
