A hybrid approach to multimodal biometric recognition based on feature-level fusion of face, two irises, and both thumbprints

open access: yesJournal of Medical Signals and Sensors, 2022
Background: The most significant motivations for designing multi-biometric systems are high-accuracy recognition, high-security assurances as well as overcoming the limitations like non-universality, noisy sensor data, and large intra-user variations ...

Effects of Different Pre-drying and Drying Methods on Volatile Compounds in the Pericarp and Kernel of Amomum tsao-ko

open access: yesFrontiers in Plant Science, 2022
The effects of twelve different pre-drying and drying methods on the chemical composition in the pericarp and kernel of Amomum tsao-ko were studied. The volatile components were isolated from the samples by simultaneous distillation and extraction and ...

On Hardy kernels as reproducing kernels

open access: yesCanadian Mathematical Bulletin, 2022
AbstractHardy kernels are a useful tool to define integral operators on Hilbertian spaces like $L^2(\mathbb R^+)$ or $H^2(\mathbb C^+)$ . These kernels entail an algebraic $L^1$ -structure which is used in this work to study the range spaces of those operators as reproducing kernel Hilbert spaces. We obtain their reproducing kernels, which in the $

Hierarchical Kernel and Sub-kernels [PDF]

open access: yesAmerican Review of Mathematics and Statistics, 2017
This paper shows the theoretical development of hierarchy by kernels and an algorithm used to obtain an interesting class or partition from a hierarchy. Also shown is the theorem about the Kernels Optimal Criterion and how it is expressed as a function of the masses of the points of the vector space and product scale points, the inertia of the cloud ...

VARIABILITY OF RACIAL COMPOSITION OF SUNFLOWER BROOMRAPE (ОROBANCHE CUMANA WALLR.) AND NEW STRATEGIES FOR PROTECTION FROM THE PARASITE

open access: yesВавиловский журнал генетики и селекции, 2018
Sunflower broomrape is a parasitic chlorophyll plant that affects the root system of the host plant, absorbing water, nutrients and toxic products from it. Germination of broomrape seeds occurs due to strigolactones released into the soil by the roots of
