Specific Impulse and Absolute Chemical Hardness [PDF]
, 2020 The present work is dedicated to show that there are relationships between the absolute chemical hardness (η) of monopropellants and their specific impulse (I s ). A total of sixteen monopropellants have been modelled and the absolute hardness obtained by quantum chemical calculations.

Interferometric method for specific impulse determination [PDF]
Optical Engineering, 2018 One of the main figures of merit in laser-ablative propulsion is the specific impulse, Isp, defined as the impulse per unit weight of fuel, and it is related to the exhaust velocity, ve, by the acceleration of gravity, Isp = ve / g. Being a key magnitude, Isp needs to be accurately determined. It is usually inferred from other measurable quantities:

Rapid Estimation of Specific Impulse
Defence Science Journal, 1988 Specific impulse (Isp) is one of the important criteria for propellant characterisation. In the present paper a semiempirical approach has been suggested to calculate Isp of composite modified doublebase(CMDB) propellant formulations by utilizing calorimetric value(Cal-Val) of the propellant composition.

Context Specificity in Stability of Hyperactivity–Impulsivity [PDF]
European Journal of Personality, 2010 This paper exemplifies a secondary data analysis of context–specific differences in children's hyperactivity–impulsivity while controlling for informant–specific effects. Participants were boys and girls from the NICHD Study of Early Child Care and Youth Development whose behaviours were measured in 1st, 3rd and 5th grades.

Using the Impulse Method to Determine High-Pressure Dynamic Burning Rate of Solid Propellants
Aerospace, 2023 A new method for determining the burning rate of a solid propellant, called the Impulse Method, is proposed in this paper. It is based on the proportional relationship between the impulse generated and the mass of the burned propellant. The pressure–time
