A modified method for satellite attitude control system in presence of novel actuators is proposed in this paper. The attitude control system is composed of three fluidic momentum controller (FMC) actuators that are used to control Euler angles and their dynamics is considered in satellite attitude equations as well. L1 adaptive control is utilized for satellite three-axial ...

This paper presents a model that describes how liquid flow fills micro-fluidic components and networks. As an alternative to computational fluid dynamic (CFD) simulations, we use a constrained energy minimization approach. This approach is based on two assumptions that hold in many micro-fluidic devices: (i) The length scales are small, and we consider slow filling rates, hence fluid momentum a...

AC-driven electrothermal flow is used to enhance the chaotic mixing through vortex flow in micro-fluidic systems by nearly an order of magnitude. Diffusion of heat and momentum can be increased because of the electrothermal force acting on the fluid through the applied AC electric field. Numerical simulation of vortex-assisted mixing in circular microchannel flow is investigated by solving a se...

We study theoretically the capturing of paramagnetic beads by a magnetic field gradient in a microfluidic channel treating the beads as a continuum. Bead motion is affected by both fluidic and magnetic forces. The transfer of momentum from beads to the fluid creates an effective bead-bead interaction that greatly aids capturing. We demonstrate that for a given inlet flow speed a critical densit...

Original scientific paper Fluidic Muscle produced by Festo Company is the most used and investigated type of pneumatic artificial muscle (PAM) actuators which can be characterized such as powerful, dynamic (even 6000 N, 50 m/s), judder-free and resistant to dirt and dust, therefore these actuators are widely used in industrial environment besides electric motors or hydraulic actuators. One of t...

The correspondence problem is an important problem when the subjects have two different kinematical structures imitating each other. In this new approach, the imitator and the imitate have totally different dynamics systems, the first one is the fluidic system, the second one is the human hand gestures. The motion of the fluidic system is composed of the combination of fluid particles which are...

A new method for online detection of peroxidase (POD) using 3D printing, active magnetic mixing, fluidic control, and optical detection was developed and demonstrated in this study. The proposed POD detection system consisted of a 3D printing and active magnetic mixing based fluidic chip for online catalytic reaction, an optical detector with a fluidic flow cell for quantitative determination o...

INTRODUCTION The need for further development of prosthetic hands with enhanced functionalities and better cosmetic appearance than conventional prosthetic hands became evident in many investigations of this topic [1-3]. Consequently, a new generation of multi-articulated hands for prosthetic application were designed in the past decade. Some of these hands are characterized by a multitude of m...
