This study makes use of the Tsallis entropy to predict the shear stress distribution. Given a definition of the Tsallis entropy, it is maximized by using the probability density function, which then is used to attain a novel shear stress equation. This is then employed for calculating the shear stress distribution in rectangular channels in different aspect ratios and finally, for viability, th...

nowday, with technology progress and the emergence of new business models, increased levels of competition and changing demands and expectations of customers, using multi channels of distribution is growing rapidly. using multiple distribution channels, despite having advantages, have many challenges as coordination and integration of these channels with high efficiency and eliminate these chal...

As is the case for all interesting questions in economics, the only good answer to this problem is “It depends.”. It is fairly easy to see how this works on intuitive grounds. Thomas’s offer in Zürich does not pay him enough to live exactly the lifestyle that he enjoys in Ann Arbor, as he would need a 60% raise to cover rent and consumption. The elasticity of substitution is key. If it is high,...

That well-being is decreasing in others' income is termed the "relative income hypothesis" (RIH) by scholars of subjective well-being (SWB) and has substantial empirical support. Some studies, however, present evidence of both positive and negative explanatory channels in the relationship between others' income and SWB. We develop a theoretical framework integrating four distinct channels throu...

modeling the heat and mass transport in micro channel is being used extensively in researches and industrial applications. the aim is optimizing fuel cell designs before building a prototype for engineering application. in this study, numerical, three-dimensional, single phase computational fluid dynamics model of a proton exchange membrane fuel cell with both the gas distribution flow channels...
