Geological Modeling Method Based on the Normal Dynamic Estimation of Sparse Point Clouds

open access: yesMathematics, 2021
The effect of geological modeling largely depends on the normal estimation results of geological sampling points. However, due to the sparse and uneven characteristics of geological sampling points, the results of normal estimation have great uncertainty.

Flood Hazard Estimation under Nonstationarity Using the Particle Filter

open access: yesGeosciences, 2020
The presence of the nonstationarity in flow datasets has challenged the flood hazard assessment. Nonstationary tools and evaluation metrics have been proposed to deal with the nonstationarity and guide the infrastructure design and mitigation measures ...

Bootstrap BCa confidence intervals for a standardized mean difference in a paired samples design using a pooled standard deviation [PDF]

open access: yesTutorials in Quantitative Methods for Psychology
A standardized mean difference in a paired samples design using a pooled standard deviation, dp, requires knowledge of the population correlation, rho, in order to generate an accurate estimate of a noncentral t confidence interval (CI).

The American Commitment to Public Propoganda [PDF]

open access: yes, 1966
Random set based methods have provided a rigorous Bayesian framework and have been used extensively in the last decade for point object estimation. In this paper, we emphasize that the same methodology offers an equally powerful approach to estimation of

The Zero-Adjusted Log-Symmetric Distributions: Point and Intervalar Estimation [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2023
In this paper, a new class of semi-continuous distributions called zero-adjusted log-symmetric is introduced and studied. Some properties and parameters estimation by maximum likelihood method are derived and confidence intervals (CIs) are developed.

Deep Learning-Based 6D Object Pose Estimation Method from Point Clouds [PDF]

open access: yesJisuanji gongcheng, 2021
Object pose estimation is a key technology required for enabling the robots to pick 3D objects in a cluttered environment. However, most of the existing deep learning methods for pose estimation rely heavily on the RGB information of the scene, which ...

Effect of Synchronizing Coordinated Base Stations on Phase Noise Estimation [PDF]

open access: yes, 2013
In this paper, we study the problem of oscillator phase noise (PN) estimation in coordinated multi-point (CoMP) transmission systems. Specifically, we investigate the effect of phase synchronization between coordinated base stations (BSs) on PN ...
