Today, injection of liquid fuels at supercritical pressures is a frequently used technique to improve the efficiency energy systems and address environmental constraints. This paper focuses on analysis coupling between hydrodynamics thermodynamics multi-species jets. Various phase transition phenomena, such as droplet formation process by condensation, which have been shown experimentally signi...
Abstract. We generalize the symmetric fourth q-Painlevé equation (q-PIV) to the noncommutative setting. Considering the symmetric q-PIV to be matrix valued, well-defined multicomponent systems are obtained. The ultradiscrete limit of these systems yields coupled multicomponent ultradiscrete systems that generalize ultradiscrete PIV. The dynamics, and specifically the integrability, of the newly...
We present a method to describe the relationship between particle dry diameter and cloud condensation nuclei (CCN) activity using a single hygroscopicity parameter κ . Values of the hygroscopicity parameter are between 0.5 and 1.4 for highly-CCN-active salts such as sodium chloride, between 0.01 and 0.5 for slightly to very hygroscopic organic species, and 0 for nonhygroscopic components. Obser...
The target echo of downward-looking radar can be simulated by a multicomponent Chirp signal with noise, which makes signal detection and parameter estimation a very important processing. Aiming at the problems of error detection caused by the cross-terms in WVDHough methods and other modified WVD distribution methods, and low precision due to poor time-frequency concentration in S-Hough transfo...
INTRODUCTION Nonpharmacological therapies (NPTs) can improve the quality of life (QoL) of people with Alzheimer's disease (AD) and their carers. The objective of this study was to evaluate the best evidence on the effects of NPTs in AD and related disorders (ADRD) by performing a systematic review and meta-analysis of the entire field. METHODS Existing reviews and major electronic databases w...
Despite the proliferation of tungstate and molybdate polyoxometalates (POMs) inclusion sulfides into these structures proved to be challenging. The use appropriate preformed thiomolybdate building blocks has over recent years developed an extensive field with a wide range diverse structural features sizes. Initial explorations focused largely either on combinatorial approach POM dimeric units o...
Analytic-bilinear approach is used to study continuous and discrete non-isospectral symmetries of the generalized KP hierarchy. It is shown that Möbius symmetry transformation for the singular manifold equation leads to continuous or discrete non-isospectral symmetry of the basic (scalar or multicomponent KP) hierarchy connected with binary Bäcklund transformation. A more general class of multi...
This paper describes some underlying principles of multicomponent and high entropy alloys, and gives some examples of these materials. Different types of multicomponent alloy and different methods of accessing multicomponent phase space are discussed. The alloys were manufactured by conventional and high speed solidification techniques, and their macroscopic, microscopic and nanoscale structure...
Stable derivatives of oxaphosphaphenanthrenes were prepared using multicomponent reactions of 3-bromo-2-naphthol, dialkyl acetylenedicarboxylate and trimethyl or triphenyl phosphite under microwave conditions with good yields.
Diffusion preserves the positivity of concentrations, therefore, multicomponent diffusion should be nonlinear if there exist non-diagonal terms. The vast variety of nonlinear multicomponent diffusion equations should be ordered and special tools are needed to provide the systematic construction of the nonlinear diffusion equations for multicomponent mixtures with significant interaction between...
