in a novel dual bed reactor fischer-tropsch synthesis was studied by using two diffrent cobalt catalysts. an alkali-promoted cobalt catalyst was used in the first bed of a fixed-bed reactor followed by a rutenuim promoted cobalt catalyst in the second bed. the activity, product selectivity and accelerated deactivation of the system were assessed and compared with a conventional single bed react...

It is a well known fact that, dual fuel engines at part loads, inevitably suffer lower thermal efficiency, higher carbon monoxide and unburned fuel emission. The work in this paper is to investigate combustion characteristics of a dual fuel (diesel-gas) engine at part loads, using a single zone combustion model with detailed chemical kinetics for combustion of natural gas fuel. The authors deve...

A method for single-cell analysis was developed by combining capillary zone electrophoresis (CZE) with electrochemical detection (ECD) using a dual electrode consisting of two different types of electrode material (carbon fiber and Au/Hg). In this method, the parallel mode was used. Different potentials were applied to both electrodes of the dual electrode. Tryptophan and glutathione, which cou...

The problem of designing an iterative learning controller in the presence of input uncertainties is of great importance in practical implementations. This paper addresses this important issue for a simple scalar nonlinear dynamic system with general input uncertainties. A dual iterative learning loop is applied to systems to “learn” both unknown dynamics and static input uncertainties respectiv...

This study investigates a voltage-controllable liquid crystals lens with a Fresnel zone electrode. When applying a proper voltage on the liquid crystal cell, a Fresnel-zone-distributed electric field is induced to direct liquid crystals aligned in a concentric structure. Owing to the concentrically aligned liquid crystals, a Fresnel lens is formed. We probe the Fresnel liquid crystal lens using...
