Developing Adaptive Differential Evolution as a New Evolutionary Algorithm, Application in Optimization of Chemical Processes

Well Placement Optimization Using Differential Evolution Algorithm

Determining the optimal location of wells with the aid of an automated search algorithm is a significant and difficult step in the reservoir development process. It is a computationally intensive task due to the large number of simulation runs required. Therefore,the key issue to such automatic optimization is development of algorithms that can find acceptable solutions with a minimum numbe...

Spatial evolution of the physico-chemical, organoleptic and bacteriological properties of a municipal artificial lake

This study is a contribution to the study of the spatial evolution of the properties of the municipal lake of Yaounde-Cameroon. The objective was the characterization of the physico-chemical, bacteriological and organoleptic parameters of water of this lake in order to provide the scientifically exploitable data. To understand the sources and the evolution of the pollution of this lake, we carr...

Application of Pd-Substituted Ni-Al Layered Double Hydroxides for the Hydrogen Evolution Reaction

Clean production of hydrogen from electrochemical water splitting has been known as a green method of fuel production. In this work, electrocatalytic hydrogen evolution reaction (HER) was investigated at new prepared layered double hydroxides (LDH) in acidic solution. NiAl/carbon black (CB) LDH was monitored using x-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, scannin...

In situ activation of a Ni catalyst with Mo ion for hydrogen evolution reaction in alkaline solution

In this study Ni catalyst have been activated during hydrogen evolution reaction (HER) by adding Mo ions into the alkaline electrolyte. After dissolving different amounts of ammonium molybdate in the 1M NaOH as electrolyte, Ni catalyst was used as cathode for HER. Afterwards a comparison between hydrogen overpotential measured in Ni catalyst with and without in situ activation has been made; th...
