Confocal laser speckle autocorrelation imaging of dynamic flow in microvasculature

open access: yesOpto-Electronic Advances, 2022
Laser speckle imaging has been widely used for in-vivo visualization of blood perfusion in biological tissues. However, existing laser speckle imaging techniques suffer from limited quantification accuracy and spatial resolution.

Process Capability Analysis in the Presence of Autocorrelation [PDF]

open access: yesJournal of Optimization in Industrial Engineering, 2011
The classical method of process capability analysis necessarily assumes that collected data are independent; nonetheless, some processes such as biological and chemical processes are autocorrelated and violate the independency assumption.

The Application of Directional Univariate Structure Functions Analysis for Studying the Spatial Anisotropy of Environmental Variables

open access: yesEkológia (Bratislava), 2019
As anisotropy is a fundamental property of the real-world environmental spatial variables, the conventional omnidirectional variograms and correlograms do not provide means enough to characterise spatial dependence between observations.

Meta-rules for Networks (Invited Paper) [PDF]

open access: yesJournal of Systemics, Cybernetics and Informatics, 2020
This article proposes conceptual approaches for both the design and implementation of network linkages, that dependent on context, should respect interlinking topological and parametric constraints, possess formal properties, be compatible with ...

On Correlation Polynomials and Subword Complexity [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2007
We consider words with letters from a $q-ary$ alphabet $\mathcal{A}$. The kth subword complexity of a word $w ∈\mathcal{A}^*$ is the number of distinct subwords of length $k$ that appear as contiguous subwords of $w$.

An Improved Map-Matching Technique Based on the Fréchet Distance Approach for Pedestrian Navigation Services

open access: yesSensors, 2016
Wearable and smartphone technology innovations have propelled the growth of Pedestrian Navigation Services (PNS). PNS need a map-matching process to project a user’s locations onto maps.

Weighted Machine Learning for Spatial-Temporal Data

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Applying machine learning techniques to spatial-temporal data poses the question that how the recorded location and time for training samples should contribute to the training and testing process. The prior knowledge of how spatial-temporal phenomena are

An Improved Ranking-Based Feature Enhancement Approach for Robust Speaker Recognition

open access: yesIEEE Access, 2016
Although the field of automatic speaker or speech recognition has been extensively studied over the past decades, the lack of robustness has remained a major challenge.
