SUMMARY We consider a Leray model with a deconvolution-based indicator function for the simulation of incompressible fluid flow at moderately large Reynolds number (in the range of few thousand) with under-resolved meshes. For the implementation of the model, we adopt a three-step algorithm called evolve-filter-relax (EFR) that requires (i) the solution of a Navier-Stokes problem, (ii) the solu...
This paper presents the implementation of a fuzzy control strategy for speed regulation an electromagnetic frequency regulator (EFR) prototype, aiming to eliminate dependence on knowledge physical parameters in most diverse operating conditions. Speed multiplication is one important steps wind power generation. Gearboxes are generally used this purpose. However, they have reduced lifespan and h...
As the water requirement for food production and other human needs grows, quantification of environmental flow requirements (EFRs) is necessary to assess the amount of water needed to sustain freshwater ecosystems. EFRs are the result of the quantification of water necessary to sustain the riverine ecosystem, which is calculated from the mean of an environmental flow (EF) method. In this study,...
Oligogalacturonides (OGs) released from the plant cell wall are active both as damage-associated molecular patterns (DAMPs) for the activation of the plant immune response and regulators of plant growth and development. Members of the Wall-Associated Kinase (WAK) family are candidate receptors of OGs, due to their ability to bind in vitro these oligosaccharides. Because lethality and redundancy...
INTRODUCTION The auditory ability to discriminate rapid changes in the envelope of language sounds is essential for speech comprehension. Human envelope-following responses (EFRs) are useful for objective measurement of temporal auditory processing in subjects who are unable to give accurate behavioural responses (e.g., young children). OBJECTIVE To evaluate age-dependent changes in EFRs duri...
In plant innate immunity, the surface-exposed leucine-rich repeat receptor kinases EFR and FLS2 mediate recognition of the bacterial pathogen-associated molecular patterns EF-Tu and flagellin, respectively. We identified the Arabidopsis stromal-derived factor-2 (SDF2) as being required for EFR function, and to a lesser extent FLS2 function. SDF2 resides in an endoplasmic reticulum (ER) protein ...
Apathy is a disabling non-motor symptom that is frequently observed in Parkinson's disease (PD). Its description and physiopathology suggest that it is partially mediated by emotional impairment, but this research issue has never been addressed at a clinical and metabolic level. We therefore conducted a metabolic study using (18)fluorodeoxyglucose positron emission tomography ((18)FDG PET) in 3...
Abstract The present study on vertical two-phase closed thermosyphon (TPCT) is aimed to determine the suitable volume-filling ratio, as a function of geometries, heat flux and vapor temperature, in order avoid potential local dryout evaporator section hence maximize performance. In study, droplet entrainment, which caused by internal counter flow during nucleate boiling within falling liquid fi...
In this paper we shall try to answer a fundamental question: how to build the Next Generation Network without disruption. The TCP/IP protocol stack has performance limits and the transparent bridge paradigm of Ethernets is complex to scale by lack of addressing hierarchy. To provide both full scalability and high performance, a new Ethernet switching architecture named Universal Ethernet Teleco...
