A deep understanding of the internal ballistic process and the factors affecting it is of primary importance to efficiently design a gun system and ensure its safe management.One of the main goals of internal ballistics is to estimate the gas pressure into the combustion chamber and the projectile muzzle velocity in here order to use the propellant
IntroductionDownsizing, and the mass layoff upheavals that ensue, has been euphemistically referred to as a short-term pain, long-term gain motovox scooter parts strategy.But is that so? Do its financial outcomes over time justify the short-run harm? And, to what extent has its adoption been driven by economic or social rationales over time?Methods
The paper presents an approach to estimate parameters of a local stationary AR(1) time series model by maximization of a local likelihood function.The method is based on a propagation-separation procedure that leads to data dependent weights defining here the local model.Using free propagation of weights under homogeneity, the method is capable of
