Micromixers are one of the most crucial components of Lab-On-a-Chip devices with the intention of mixing and dispersion of reagents like small molecules and particles. The challenge facing micromixers is typically insufficient mixing efficiency in basic designs, which results in longer microchannels. Therefore, it is desirable to increase mixing efficiency, in order to decrease mixing length, w...

RoboAnalyzer is a software based on 3Dmodel of robots. It was developed primarily for teaching and learning of robot mechanics, although it is robust enough for the use by researchers as well. The motive behind the development of RoboAnalyzer was mainly to help teachers and students get started with teaching/learning of robotics using template-based skeleton models or CAD models of serial robot...

Attempts have been made to define new classes of distributions that provide more flexibility for modeling data is skewed in nature. In this work, we propose a family namely the Marshall-Olkin Half Logistic-G (MO-HL-G) based on generator pioneered by [Marshall and Olkin , 1997]. This allows flexible fit real from several fields, such as engineering, hydrology, survival analysis. The structural p...

An accurate mathematical inference depends on the experimental design and model adopted in process. Thus, this study Marshall – Olkin Teissier generated distribution was used to present of true nature lifetime data. The characteristics proposed were examined a closed form. behaviour new indicated that hazard rate submodels could be J- U-shaped, decreasing increasing. Monte Carlo simulations pre...

This paper presents a novel shape-optimization technique for the design of mixing elements in single-screw extruders. Extruders enable continuous production constant-cross-section profiles. Equipped with one or several screw-shaped rotors, extruders transport polymer particles towards outlet. Due to shear heating, melting is induced and melt stream created, which can be further processed. While...

Residence time control is an important indicator of micromixer design. When using vortex shedding to enhance mixing efficiency in a micromixer, the relationship between residence time and vortex shedding becomes important; if residence time is shorter than shedding time, the fluid elements flow through the channel too quickly with no contribution of vortex shedding to mixing. Both residence tim...

We present a design of a microfluidic mixer based on hydrodynamic focusing which is used to initiate the folding process (i.e., changes of the molecular structure) of a protein. The folding process is initiated by diluting (from 90% to 30%) the local denaturant concentration (initially 6 M GdCl solution) in a short time interval we refer to as mixing time. Our objective is to optimize this mixe...

Abstract: In this paper the geometric process is used for the analysis of accelerated life testing for Marshall-Olkin Extended Exponential (MOEE) distribution using Type I censored data. Assuming that the lifetimes under increasing stress levels form a geometric process, the parameters are estimated by using the maximum likelihood method and the original parameters instead of the developing inf...
