Definition of Specific Impulse

The Journal of the Royal Aeronautical Society, 1954
The collected comments of Messrs. Greenwood (December 1953 and October 1954 JOURNAL), Thorne (February and October 1954 JOURNAL), and Asquith and Whitaker (May and October 1954 JOURNAL) on the definition of specific impulse in the field of rocket propulsion argue certain traditional points of view, each of which has enough merit to gain proponents but ...

Cognitive impulsivity in specific learning disabilities

European Child & Adolescent Psychiatry, 2005
Many studies on cognitive impulsivity in learning disabled children have been criticized for their methodological limitations, and they have not dealt with the different types of learning disability. The aim of this study was to overcome these limitations and to assess if there was a significant cognitive impulsivity in reading disorder and/or spelling

Definition of specific impulse

Journal of Spacecraft and Rockets, 1953
Regarding the recent Technical Note of Mr. RAsquith and Mr. Whitaker (May 1954 journal):1. The dependence of the weight of a given mass on location is a sufficient reason for the abolition of the ” weight” definition of specific impulse. This is likely to become increasingly apparent as rockets penetrate further into interplanetary space.2.

Impulsivity and risk for mania: Towards greater specificity

Psychology and Psychotherapy: Theory, Research and Practice, 2012
Background Impulsivity is elevated among people diagnosed with bipolar disorder, and recent evidence suggests that impulsivity can predict onset among those at risk for the disorder. Impulsivity, though, is a broad construct. Objective

Specific pattern of attentional changes in impulsive individuals

Cognitive Neuropsychiatry, 2006
Although impulsivity is recognised as a major psychopathological feature, its cognitive correlates remain controversial. We evaluated readiness to act induced by a warning signal and attentional engagement in healthy impulsive participants.People with high impulsivity scores (HI) and low impulsivity (LI) scores on Barratt's Impulsivity Scale (BIS) were

Specific Impulse Prediction of Solid-Propellant Motors

Journal of Spacecraft and Rockets, 1979
The methods for the theoretical prediction of delivered specific impulse are relatively well known. They involve computing the losses due to two-phase flow, divergence, boundary layer, kinetics, nozzle submergence, and combustion inefficiency. The largest computed loss in typical aluminized solid propellants is the two-phase flow loss; this computation

Dimensions and disorder specificity of impulsivity in pathological gambling

Addictive Behaviors, 2014
Impulsivity is a core characteristic of pathological gambling (PG), even though the underlying structure and disorder specificity is unclear. This study aimed to explore different dimensions of impulsivity in a clinical sample including PG. Furthermore, we aimed to test which alterations of the impulsivity-related dimensions are disorder specific for ...

Space System Specific Impulse

Journal of the Aerospace Sciences, 1961
Abstract : The system specific impulse (Iss) was determined to be the equivalent of specific impulse (Isp) of an idealized system having the same net effectiveness as the actual system but with zero mass of all structural equipment except the payload.

The Specifics of Closed-Loop Impulse Control

IFAC Proceedings Volumes, 2014
Abstract This paper deals with the problem of designing feedback solutions for systems with impulsive control inputs which meets increasing demand. It emphasizes the specifics of such solutions. Their description opens routes for effective calculation and application.
