Fuel Grain Configuration Adaptation for High-Regression-Rate Hybrid Propulsion Applications
Low regression rate is the most critical issue for the development and application of hybrid rocket motors (HRMs). Paraffin-based fuels are potential candidates for HRMs due to their high regression rates but adding polymers to improve strength results ...

Crack Growth Rate Model Derived from Domain Knowledge-Guided Symbolic Regression
Machine learning (ML) has powerful nonlinear processing and multivariate learning capabilities, so it has been widely utilised in the fatigue field. However, most ML methods are inexplicable black-box models that are difficult to apply in engineering ...

Adaptive goodness-of-fit tests based on signed ranks [PDF]
Within the nonparametric regression model with unknown regression function $l$ and independent, symmetric errors, a new multiscale signed rank statistic is introduced and a conditional multiple test of the simple hypothesis $l=0$ against a nonparametric ...

Familywise Error Rate Control via Knockoffs [PDF]
We present a novel method for controlling the $k$-familywise error rate ($k$-FWER) in the linear regression setting using the knockoffs framework first introduced by Barber and Cand\`es.

A general asymptotic scheme for inference under order restrictions
Limit distributions for the greatest convex minorant and its derivative are considered for a general class of stochastic processes including partial sum processes and empirical processes, for independent, weakly dependent and long range dependent data ...

Robust nonparametric estimation via wavelet median regression [PDF]
In this paper we develop a nonparametric regression method that is simultaneously adaptive over a wide range of function classes for the regression function and robust over a large collection of error distributions, including those that are heavy-tailed,

Analyses of Developmental Rate Isomorphy in Ectotherms: Introducing the Dirichlet Regression. [PDF]
Temperature drives development in insects and other ectotherms because their metabolic rate and growth depends directly on thermal conditions. However, relative durations of successive ontogenetic stages often remain nearly constant across a substantial ...
