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

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

Optimization of Variable-Specific-Impulse Interplanetary Trajectories

AIAA/AAS Astrodynamics Specialist Conference and Exhibit, 2002
An indirect optimization method is used to find optimal trajectories that use solar electric propulsion. Missions that exploit variable specific impulse are compared to constant-specific-impulse trajectories, and the benefit, in terms of payload, is highlighted. The presence of limits on the attainable values of the specific impulse and the use of dual-

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.

Derivation of circuit specification for the UWB impulse radio transceivers

Proceedings of 2010 IEEE International Symposium on Circuits and Systems, 2010
To satisfy the huge demand for unlicensed handheld wireless networking devices, the Federal Communications Commission (FCC, USA) made the application of ultra-wideband (UWB) technology possible in 2002. Since then an IEEE standard has already been approved for the physical layer of the UWB impulse radio networking devices. Because of the ultra-wideband

Domain-Specific Relationships in Sexual Measures of Impulsive Behavior

Archives of Sexual Behavior, 2018
Impulsivity is an important construct for understanding sexual behaviors, but behavioral and self-report measures of impulsivity often are not correlated. One possible explanation for this is that there is little shared variance in the measures because behavioral measures index impulsivity by asking questions about monetary preferences, while self ...

Specific Afferent Impulses and Cutaneous Sensibility

The Journal of General Psychology, 1932
Resume LES IMPULSIONS AFFERENTES SPECIFIQUES ET LA SENSIBILITE CUTANEE 1. On analyse les etudes recentes qui montrent des temoignages de l'existence des impulsions afferentes specifiques des nerfs. Il existe beaucoup de temoignages qui indiquent une correlation generale des aspects quantitatifs de l'action potentielle des fibres afferentes des nerfs ...
