Regression Rates Study of Mixed Hybrid Propellants

Journal of Propulsion and Power, 2005
The low regression rates of classic hybrid rocket fuels lead to large internal ports that limit potential applications. This experimental study investigated the increase in regression rate that results from adding a solid oxidizer and a catalyst to a hybrid fuel grain.

Optimal learning rates for distribution regression

Journal of Complexity, 2020
A learning algorithm is studied for distribution regression with regularized least squares (RLS). The algorithm contains two stages of samples and aims at regressing from distributions to real valued outputs. The first stage sample consists of (unknown) probability distributions \(x_i, i=1,\ldots,l,\) and the second stage sample consists of the data ...

Hazard Rate Regression Using Ordinary Nonparametric Regression Smoothers

Journal of Computational and Graphical Statistics, 1996
Abstract This article proposes a method for nonparametric estimation of hazard rates as a function of time and possibly multiple covariates. The method is based on dividing the time axis into intervals, and calculating number of event and follow-up time contributions from the different intervals.
