Multikernel Graph Structure Learning for Multispectral Point Cloud Classification

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Multispectral point cloud, with spatial and multiple-band spectral information, provides the data basis for finer land cover 3-D classification. However, spectral information is not well utilized by traditional methods of point cloud classification ...

Central limit theorems for iterated random Lipschitz mappings

open access: yes, 2004
International audienceLet M be a noncompact metric space in which every closed ball is compact, and let G be a semigroup of Lipschitz mappings of M. Denote by (Yn)n≥1 a sequence of independent G-valued, identically distributed random variables (r.v.'s ...

A neural network method for nonlinear hyperspectral unmixing

open access: yes, 2018
: Because of the complex interaction of light with the Earth surface, a hyperspectral pixel can be composed of a highly nonlinear mixture of the reflectances of the materials on the ground.

Spectral and variational analysis of generalized cylindrical and elliptical strip and microstrip lines [PDF]

open access: yes, 1990
The variational technique in the spectral domain (VTSD) is shown to be an efficient method for computing the quasi-TEM parameters of arbitrary multiconductor and multidielectric cylindrical or elliptical strip configurations.

Mordo2: A Personalization Framework for Silent Command Recognition

open access: yesIEEE Transactions on Neural Systems and Rehabilitation Engineering
Wearable human-computer interactions in daily life are increasingly encouraged by the prevalence of intelligent wearables. It poses a demanding requirement of micro-interaction and minimizing social awkwardness.

Multiband image fusion via linear mappings [PDF]

open access: yes, 2019
Despite the development of more sophisticated airborne systems that are equipped with hy-perspectral sensors, the more cost effective commercially sponsored multispectral satellite sys-tems are still in use today.

A Unified Gas-Kinetic Immersed Boundary Method for Non-Equilibrium Fluid-Structure Interactions

open access: yes气体物理
This study addressed key challenges in numerical simulations of the coupling between multi-scale flows and immersed bodies, including the breakdown of continuum assumptions, prohibitive costs of dynamic mesh regeneration, and difficulties in enforcing ...

Lifetime and spectral response mappings on cristalline Silicon

open access: yes, 1999
This master thesis covers generation and recombination of minority charge carriers in (multi-) crystalline silicon. Lifetime mappings were recorded using a microwave-detected photo- conductance decay measurement (µ-PCD method).

Hyper-Spectral Image Analysis with Partially-Latent Regression and Spatial Markov Dependencies [PDF]

open access: yes, 2015
International audienceHyper-spectral data can be analyzed to recover physical properties at large planetary scales. This involves resolving inverse problems which can be addressed within machine learning, with the advantage that, once a relationship ...

Linear differential operators with distribution coefficients of various singularity orders

open access: yes, 2022
In this paper, the linear differential expression of order $n \ge 2$ with distribution coefficients of various singularity orders is considered. We obtain the associated matrix for the regularization of this expression.
