Electroosmotic flow (EOF) commonly involves inhomogeneous fluids in practical applications. EOF hysteresis, which is defined as direction-dependent behavior, has been extensively investigated for dissimilar solution pair systems. Hitherto, there no investigation being conducted to examine the effect of microchannel diameter on hysteresis phenomenon. In this investigation, current monitoring exp...

We study in this paper the control of hysteresis-based actuator systems where its remanence behavior (e.g., remaining memory when actuation signal is set to zero) must follow a desired reference point. present recursive algorithm for output regulation hysteresis remnant described by Preisach operators. Under some mild conditions, we prove that our proposed guarantees converges value. Simulation...

The multiphase nature of the flow in porous media is characterized by hysteretic effects on the macroscopic level. These effects have a significant influence on the behavior of the whole system and therefore have to be taken into account. The aim of this subproject is to develop and implement models describing the hysteresis in the context of the CO2 sequestration process.The hysteresis relatio...

We modify the kinetic Ising model with Metropolis dynamics, allowing each spin to interact only with q spins randomly chosen from the whole system, which corresponds to the topology of a complete graph. We show that the model with q≥3 exhibits a phase transition between ferromagnetic and paramagnetic phases at temperature T*, which linearly increases with q. Moreover, we show that for q=3 the p...

Ferroelectric (e.g., PZT and PMN) and ferromaqnetic (e.g., Terfenol-D) materials exhibit high energy densities, broadband drive capabilities, and the capacity for both actuating and sensing. This makes them attractive as compact transducers for applications including nanopositioning systems such as atomic force microscopes (AFM), acoustic transducers, and drive mechanisms for high speed milling...

Pharmaceutical compounds (PCs) and dissolved organic matter (DOM) are co-introduced into soils by irrigation with reclaimed wastewater. We targeted carbamazepine (CBZ) as a model compound to study the tertiary interactions between relatively polar PCs, DOM, and soil. Sorption-desorption behavior of CBZ was studied with bulk clay soil and the corresponding clay size fraction in the following sys...

In this paper we investigate the behavior of higher order Galerkin expansions of the Moore-Greitzer model of general transients in aeroengine compression systems. We assume steady state en-trainment of the higher Fourier modes of the rotating stall cell which establishes a framework for a simpli-ed numerical analysis of the bifurcating solutions corresponding to rotating stall. For small values...

Abstract—In this paper, an advanced Nonlinear Exponential Model (NEM), able to simulate the uniaxial dynamic behavior of seismic isolators having a continuously decreasing tangent stiffness with increasing displacement in the relatively large displacements range and a hardening or softening behavior at large displacements, is presented. The mathematical model is validated by comparing the exper...

In this paper we investigate the behavior of higher order Galerkin expansions of the MooreGreitzer model of general transients in aeroengine compression systems. We assume steady state entrainment of the higher Fourier modes of the rotating stall cell which helps establish a framework for a simpli ed numerical analysis of the bifurcating solutions corresponding to rotating stall. For small valu...
