Analysis of mobility data – A focus on Mobile Mapping Systems

open access: yesGeo-spatial Information Science, 2020
The increasing availability of devices to capture the position of moving objects (and other environmental information) leads to a very large amount and variety of mobility data.

Automatic Analysis of Trough Lines Based on Curvature Tracing

open access: yesAtmosphere, 2018
To solve the problems that arise in traditional automatic methods for trough line analysis with regard to low processing efficiency and analytical accuracy, an automatic method for trough line analysis was proposed in this study, comprising the following

Weighted Group Sparse Regularized Tensor Decomposition for Hyperspectral Image Denoising

open access: yesApplied Sciences, 2023
Hyperspectral imaging (HSI) has been used in a wide range of applications in recent years. But in the process of image acquisition, hyperspectral images are subject to various types of noise interference. Noise reduction algorithms can be used to enhance

Wind Turbine Active Fault Tolerant Control Based on Backstepping Active Disturbance Rejection Control and a Neurofuzzy Detector

open access: yesEnergies, 2023
Wind energy conversion systems have become an important part of renewable energy history due to their accessibility and cost-effectiveness. Offshore wind farms are seen as the future of wind energy, but they can be very expensive to maintain if faults ...

Automatic Analysis of the NRL Pump

open access: yesElectronic Notes in Theoretical Computer Science, 2004
We define a probabilistic model for the NRL Pump and using FHP-murϕ show experimentally that there exists a probabilistic covert channel whose capacity depends on various NRL Pump parameters (e.g. buffer size, number of samples in the moving average, etc).

Automatic RQD analysis method based on information recognition of borehole images

open access: yesYantu gongcheng xuebao, 2020
RQD is an important index for evaluating the integrity of rock masses. The traditional methods are greatly affected by drilling process, core quality and run length, and cannot objectively reflect the quality of rock masses.

Method for an automatic analysis of the ECG

open access: yesJournal of Biomedical Engineering, 1988
A method is presented for an analysis of the ECG. Using cubic spline techniques we proceed first to a smoothing of the signal and then to the elimination of baseline drift. The properties of the calculated derivatives are used to establish criteria for the identification of the ECG waves and the measurement of their essential parameters.
