Testing in Nonparametric Accelerated Life Time Models
where T0 is the so-called baseline life time and T is the observable life time. We will assume that T is an absolute continuous random variable (r.v.) and that the covariate X does not depend on the time. For simplicity of presentation let X be one-dimensional. For statistical application a suitable choice of the acceleration function is important and the problem of testing ψ arises. A survey o...
متن کاملRun-out Effects of Debris Flows Based on Numerical Simulation
Debris flows are a common natural disaster in mountainous areas and often cause severe casualties and property loss. Debris-flow run-out effects analysis can provide an idea of the spatial risks posed to the downstream area of a debris flow, which is extremely important for local populations’ lives, disaster mitigation and planning the layout of economic construction. The objective of this stud...
متن کاملNumerical Analysis of Grease Film Characteristics in Tapered Roller Bearing Subject to Shaft Deflection
The shaft deflection is one of critical factors that deteriorate the grease lubrication state inside the tapered roller bearings (TRBs). So, in this paper, on the premise of the TRB subjected to the combined loads and the shaft is deflected, the grease lubrication model at the TRB contacts was constructed, in which the interaction loads, linear and angular displacements of the bearing parts wer...
متن کاملBayesian Accelerated Life Testing
In this paper a Bayesian approach for accelerated life testing will be considered. It will be assumed that the failure times at the different stress levels follow a Weibull distribution and exponential distribution, respectively. In accelerated life tests, the components are exposed to an environment that is more severe that the usual environment, such that the components will fail in a shorter...
متن کاملAccelerated C-Arm Reconstruction by Out-of-Projection Prediction
3D image reconstruction from C-arm projections is a computationally demanding task. However, for interventional procedures a fast reconstruction is desirable. We present a method to reduce the number of actually back-projected voxels and ultimately the processing time by 20–30% without affecting image quality. The proposed method detects and skips subvolumes that are not visible in the current ...
