Quantitative assessment in thermal image segmentation for artistic objects
No full textThe application of the thermal and infrared technology in different areas of research is considerably increasing.
These applications involve Non-destructive Testing (NDT), Medical analysis (Computer Aid Diagnosis/Detection-
CAD), Arts and Archaeology among many others. In the arts and archaeology field, infrared technology provides
significant contributions in term of finding defects of possible impaired regions. This has been done through a
wide range of different thermographic experiments and infrared methods. The proposed approach here focuses
on application of some known factor analysis methods such as standard Non-Negative Matrix Factorization
(NMF) optimized by gradient-descent-based multiplicative rules (SNMF1) and standard NMF optimized by
Non-negative least squares (NNLS) active-set algorithm (SNMF2) and eigen decomposition approaches such as
Principal Component Thermography (PCT), Candid Covariance-Free Incremental Principal Component Thermography (CCIPCT) to obtain the thermal features. On one hand, these methods are usually applied as
preprocessing before clustering for the purpose of segmentation of possible defects. On the other hand, a wavelet
based data fusion combines the data of each method with PCT to increase the accuracy of the algorithm. The
quantitative assessment of these approaches indicates considerable segmentation along with the reasonable computational complexity. It shows the promising performance and demonstrated a confirmation for the outlined
properties. In particular, a polychromatic wooden statue and a fresco were analyzed using the above mentioned
methods and interesting results were obtained

On the role of inertia in channel flows of finite-size neutrally buoyant particles
No full textWe consider suspensions of finite-size neutrally buoyant rigid spherical particles in channel flow and investigate the relevance of different momentum transfer mechanisms and the relation between the local particle dynamics and the bulk flow properties in the highly inertial regime. Interface-resolved simulations are performed in the range of Reynolds numbers 3000 <= Re <= 15 000 and solid volume fractions 0 <= phi <= 0.3. The Lagrangian particle statistics show that pair interactions are highly inhomogeneous and dependent on the distance from the wall: in their vicinity, the underlying mean shear drives the pair interactions, while a high degree of isotropy, dictated by more frequent collisions, characterizes the core region. Analysis of the momentum balance reveals that while the particle-induced stresses govern the dynamics in dense conditions, phi = 0.3, and moderate Reynolds numbers, Re < 10 000, the turbulent stresses take over at higher Reynolds numbers. This behaviour is associated with a reduced particle migration toward the channel core, which decreases the importance of the particle-induced stress and increases the turbulent activity. Our results indicate that Reynolds stresses and the associated velocity fluctuations, characteristics of near-wall turbulence, prevail at high inertia over the resistance to deformation presented by the particles for volume fractions lower than 30 %
Germination and seedling growth responses of zygophyllum fabago, salsola kali l. And atriplex canescens to peg-induced drought stress
No full textIn arid and semi-arid regions, planting drought-tolerant species is the most useful strategy in the reclamation of degraded soils. In the present study, we evaluated the effect of simulated drought by polyethylene glycol (PEG-6000) on seed germination and seedling growth of three desert plants such as Atriplex canescens, Salsola kali and Zygophyllum fabago. Seeds were subjected to water stress to drought stress by PEG at five stress levels (0, −1, −4, −8, −12, −14 bars). Germination of Z. fabago was completely inhibited at an osmotic potential of −8, −10 and −12 bars and the germination of A. canescens was inhibited only at −14 bar. In contrast, S. kali responded positively to high levels of stress and our results showed the highest final germination percent (71.75, 54 and 18.25%) under three-drought stress −8, −12 and −14 bars, respectively. In addition, increasing PEG concentration adversely affected the germination rate and seedling vigor index as well as the root and shoot length of species. Under high stress levels, S. kali achieved a higher germination rate and seedling vigor index compared to Z. fabago and A. canescens. Among species, S. kali was the only one able to develop roots and shoots at −14 bar. Therefore, S. kali could be considered as a promising plant for the rehabilitation of degraded soils at risk of desertification
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
