Adjointness of Suspension and Shape Path Functors [PDF]

open access: yesMathematics Interdisciplinary Research, 2021
In this paper, we introduce a subcategory ∼Sh* of Sh* and obtain some results in this subcategory. First we show that there is a natural bijection Sh(∑(X, x), (Y,y))≅Sh((X,x),Sh((I, Ī),(Y,y))), for every (Y,y)∈ ~Sh* and (X,x)∈ Sh*. By this fact, we prove

Studying the stability of aqueous suspensions of multiwalled carbon nanotubes used for the modification of composite materials

open access: yesEngineering Structures and Technologies, 2014
In this paper, the stability of aqueous suspensions of multiwalled carbon nanotubes (MWCNTs) has been studied with physical and chemical methods. The optimum dispersion time of MWCNT suspension in a rotary homogenizer has been found.

Control of Automotive Semi-Active MR Suspensions for In-Wheel Electric Vehicles

open access: yesApplied Sciences, 2020
In this work, four different semi-active controllers for a quarter of vehicle and full vehicles are evaluated and compared when used in internal combustion engine (ICE) vehicles vs electric vehicles (EVs) with in-wheel motor configuration as a way to ...

Collective chemotactic dynamics in the presence of self-generated fluid flows

open access: yes, 2012
In micro-swimmer suspensions locomotion necessarily generates fluid motion, and it is known that such flows can lead to collective behavior from unbiased swimming. We examine the complementary problem of how chemotaxis is affected by self-generated flows.

An optimal self-excited heating method for biogas production under cold climate

open access: yesThe Journal of Engineering, 2019
Biogas, as the product of anaerobic fermentation, is one of the main routes to utilize bioenergy. The biogas production rate is determined by lots of factors, of which temperature determines most. However, when operating in the cold climate or cold areas,

Numerical simulation of flotation bubble motion in a three-phase inner suspension fluid

open access: yes工程科学学报, 2016
To find the motion law and optimum size of floatation bubbles in a three-phase flow,the Eulerian model is used to simulate the motion process of bubbles with different initial diameters in pulps of different concentrations.
