Developments in Vibrator Control

EAGE Vibroseis Workshop - Vibroseis acquisition and processing half century later, new developments in data quality and productivity, 2008
ABSTRACTHydraulic limitations, non‐rigidity of the baseplate as well as variable characteristics of the ground constantly distort the downgoing energy output by vibrators. Therefore, a real time feedback control must be performed to continuously adjust the emitted force to the reference pilot signal. This ground force is represented by the weighted sum

Control of photoreceptor development

Current Opinion in Neurobiology, 1992
Recent studies of cell type determination in the vertebrate retina suggest that rod photoreceptor development involves interactions among cells that are mediated, at least in part, by temporally regulated diffusible signals. In this review the strategies used to generate rods in the vertebrate retina are compared with those described for photoreceptor ...

Control of Early Seed Development

Annual Review of Cell and Developmental Biology, 2001
▪ Abstract  Seed development requires coordinated expression of embryo and endosperm and has contributions from both sporophytic and male and female gametophytic genes. Genetic and molecular analyses in recent years have started to illuminate how products of these multiple genes interact to initiate seed development.

DEVELOPMENT IN SUBSEA CONTROLS

Proceedings of Offshore Europe, 1989
Abstract Autonomous control of subsea installations is an ideal which has received a lot of attention but which so far remains an elusive goal, while the ubiquitous umbilical stoically continues to be the lifeline to subsea control. This paper is set out in debate format and traces the advances in subsea control, using the

The Development and Control of NEW DRUGS

AJN, American Journal of Nursing, 1962
NEW DRUGS OFFER a promise of relief from disease and suffering. Consequently, they are of primary interest to the afflicted and of general interest to almost everyone. The lay press rightly recognizes them as newsworthy and issues an almost continuous stream of reports on the development of new remedies.

Neurotrophic control of ovarian development

Microscopy Research and Technique, 2002
AbstractSubstantial evidence now exists indicating that the neurotrophins, a family of growth factors required for the survival, development, and differentiation of various neuronal populations of the nervous system, are also important for the development of nonneuronal tissues.

Neuronal control of development in hydra

The International Journal of Developmental Biology, 1996
Hydra is an excellent model system for developmental biology, because pattern formation processes can be easily studied in regeneration, transplantation, and reaggregation experiments. At the cellular level hydra has the advantage that it contains only a few basic cell types and that differentiation pathways are short.

Development of Attentional and Oculomotor Control.

Developmental Psychology, 2005
The present study was conducted to examine the development of attentional and oculomotor control. More specifically, the authors were interested in the development of the ability to inhibit an incorrect but prepotent response to a salient distractor.

Developer behaviour and development control

Land Development Studies, 1987
Summary Studies by the North Carolina group established the decision modelling approach to study urban growth. These studies established the central role played by developers in the process, and the rational and adaptive behaviour of developer decision‐making.
