Along with almost a hundred research communications this volume
contains six invited lectures of lasting value. They cover modeling
in plasma dynamics, the use of parallel computing for simulations
and the applications of multigrid methods to Navier-Stokes
equations, as well as other surveys on important techniques. An
inaugural talk on computational fluid dynamics and a survey that
relates dynamical systems, turbulence and numerical solutions of
the Navier-Stokes equations give an exciting view on scientific
computing and its importance for engineering, physics and
mathematics.
The ability to predict and control viscous flow phenomena is
becoming increasingly important in modern industrial application.
The Instability and Transition Workshop at Langley was extremely
important in help ing the scientists community to access the state
of knowledge in the area of transition from laminar to turbulent
flow, to identify promising future areas of research and to build
future interactions between researchers worldwide working in the
areas of theoretical, experimental and computational fluid and aero
dynamics. The set of two volume contains panel discussions and
research contribution with the following objectives: (1) expose the
academic community to current technologically important issues of
instability and transitions in shear flows over the entire speed
range, (2) acquaint the academic community with the unique
combination of theoretical, computational and experimental
capabilities at LaRC and foster interaction with these facilities.
(3) review current state-of-the-art and propose future directions
for instability and transition research, (4) accelerate progress in
elucidating basic understanding of transition phenomena and in
transferring this knowledge into improved design methodologies
through improved transition modeling, and (5) establish mechanism
for continued interaction."
These two volumes contain the proceedings of the workshop on the
Institute for Computer Instability and Transition, sponsored by
Applications in Science and Engineering (ICASE) and the Langley
Research Center (LaRC), during May 15 to June 9, 1989. The work
shop coincided with the initiation of a new, focused research pro
gram on instability and transition at LaRC. The objectives of the
workshop were to (i) expose the academic community to current
technologically important issues of instability and transition in
shear flows over the entire speed range, (ii) acquaint the academic
com munity with the unique combination of theoretical,
computational and experimental capabilities at LaRC and foster
interaction with these facilities, (iii) review current
state-of-the-art and propose fu ture directions for instability and
transition research, (iv) accelerate progress in elucidating basic
understanding of transition phenomena and in transferring this
knowledge into improved design methodolo gies through improved
transition modeling, and (v) establish mech anisms for continued
interaction. The objectives (i) to (iii) were of course immediately
met. It is still premature to assess whether ob jectives (iv) and
(v) are achieved. The workshop program consisted of tutorials,
research presenta tions, panel discussions, experimental and
computational demonstra tions, and collaborative projects.
Expanded and fully updated, the second edition of this popular
resource provides essential information to help primary pediatric
care providers to more confidently evaluate and care for children
with developmental and behavioral concerns. New chapters cover:
Environmental and biological influences on child development and
behavior Development and disorders of feeding, sleep, and
elimination Assimilation of developmental-behavioral
screening/surveillance/evaluation/diagnosis, referral, and
management into primary care pediatric practice Topics with updated
information include: The role of early childhood adversity and
toxic stress and the impact on child development and behavior How
to appropriately bill and code for care Evidence-based
interventions, including psychopharmacology Developmental screening
and surveillance, autism spectrum disorder, and ADHD Other topics
include counseling children and families, anxiety and mood
disorders, and transitioning to adult medical care.
Describes a selection of important parallel algorithms for matrix
computations. Reviews the current status and provides an overall
perspective of parallel algorithms for solving problems arising in
the major areas of numerical linear algebra, including (1) direct
solution of dense, structured, or sparse linear systems, (2) dense
or structured least squares computations, (3) dense or structured
eigenvaluen and singular value computations, and (4) rapid elliptic
solvers. The book emphasizes computational primitives whose
efficient execution on parallel and vector computers is essential
to obtain high performance algorithms. Consists of two
comprehensive survey papers on important parallel algorithms for
solving problems arising in the major areas of numerical linear
algebra - direct solution of linear systems, least squares
computations, eigenvalue and singular value computations, and rapid
elliptic solvers, plus an extensive up-to-date bibliography (2,000
items) on related research.
This volume reviews, in the context of partial differential
equations, algorithm development that has been specifically aimed
at computers that exhibit some form of parallelism. Emphasis is on
the solution of PDEs because these are typically the problems that
generate high computational demands. The authors discuss
architectural features of these computers insomuch as they
influence algorithm performance, and provide insight into algorithm
characteristics that allow effective use of hardware. Both direct
and indirect methods are given for elliptic equations as well as
explicit and implicit methods for initial boundary-value problems.
The intent is to point out attractive methods as well as areas
where this class of computer architecture cannot be fully utilized
because of either hardware restrictions or the lack of adequate
algorithms.
