Recently we proposed a novel nonlinear control design for active suspensions, which features a lter whose band-width is a nonlinear function of suspension travel; this lter results in an improved tradeoo between ride comfort and rattlespace usage. In this paper we augment this controller with a new road-adaptive algorithm which continuously monitors suspension travel and adjusts on-line the sha...

The paper industry has a number of processes where the rheology is complex and critical to control for trouble free operation. The rheological properties of pulp suspensions and paper coatings are reviewed here. The flow, rheology and other various phenomena are discussed for pulp suspensions. The particle level models that have been developed for pulp suspensions are compared to experimental r...

The present work is a systematic numerical study of the thermal properties of single walled carbon nanotubes (SWNTs) in suspensions. A computational model, based on the simulation of the random movement of Brownian thermal walkers in aqueous and in oil suspensions of SWNTs, was used to investigate the effect of the SWNT aspect ratio, weight fraction and of the interfacial thermal resistance on ...

Colloidal suspensions are simple model systems for the study of phase transitions. Video microscopy is capable of directly imaging the structure and dynamics of colloidal suspensions in different phases. Recent results related to crystallization, glasses, and 2D systems complement and extend previous theoretical and experimental studies. Moreover, new techniques allow the details of interaction...

We report a thermosensitive microgel suspension that can be tuned reversibly between the glass state at low temperature and the liquid state at high temperature. Unlike hard spheres, we find that the glass transition for these suspensions is governed by both the volume fraction and the softness of the particles, where softer suspensions form a glass at higher effective volume fractions. In the ...

Partially purified suspensions of typhus rickettsiae have been shown to exhibit metabolic activity as evidenced by consumption of oxygen and production of carbon dioxide in the presence of glutamate. Similar activity at a much lower rate occurs in the presence of pyruvate. The rate of oxygen uptake was directly proportional to the concentration of viable rickettsiae, as estimated by their toxic...

We have devised a method that employs moving electrode electrochemical impedance spectroscopy to monitor the sedimentation of particles in conductive suspensions. In contrast standard cells with fixed geometry, our cell has flexible design movable counter allows precise adjustment distance. Measuring electrical at various spacings and utilizing linear dependence this function on displacement en...

This paper presents a novel method for the fault detection and isolation for rail vehicle suspensions that explores the additional dynamic interactions between different motions of a bogie or body caused by the failure of suspension components by taking advantage of symmetrical mechanical configurations of railway bogies. The study is focused on the monitoring of the vertical primary suspension...

We perform the extensive Brownian dynamics simulations on the suspensions of the monodisperse magnetic colloidal chains confined in the thin films at several different area fractions. It is shown that the long-time self-diffusion coefficients of the colloidal chains with different chain lengths converge on the single master curve, even though the area fraction of the chains is different. We als...
