Electrochemical Advanced Oxidation Processes (EAOPs) for Disinfecting Water—Fresh Perspectives

Djamel Ghernaout, Noureddine Elboughdiri, Saad Ghareba, Alsamani Salih
During recent decades, study endeavors have been performed at elaborating more efficient techniques for handling waters carrying pathogens. Among such methods, the famous electrochemical advanced oxidation processes (EAOPs) have induced augmenting attention. Such methods are founded on electro-chemically producing powerful oxidants like hydroxyl radicals (●OH). This work portrays a global view on killing different microorganisms by some usual EAOPs. Electrochemically-driven techniques are earnin...

Standard Cell Placement Optimization Using Quadratic Placement Algorithm

Suren Abazyan, Narek Mamikonyan
Designs including tens of millions of standard cells in one chip are commonly used in current IC projects, so finding optimal location on a chip surface for each logic cell is a very important step in IC design. Apart from finding room for logic cell placement with minimum chip area, length of connecting wires is also playing big role and needs to be taken under control. In this paper, research and implementation of standard cell placement-optimizations’ quadratic algorithm is described. Main re...

Electrochemical Engineering in the Core of the Dye-Sensitized Solar Cells (DSSCs)

Djamel Ghernaout, Attia Boudjemline, Noureddine Elboughdiri
Dye-sensitized solar cells (DSSCs) are classed in the category of thin-film solar cells, which have been under thorough investigation during the last thirty years thanks to their low price, easy fabrication procedure, low toxicity and ease of generation. Even now, there are great efforts to substitute the present DSSC materials because of their elevated price, less abundance, and long-term stability. The performance of present DSSCs attains 12%, employing Ru(II) dyes via regulating material and ...

Static IR Drop Estimation on the Power Network

S. S. Abazyan, N. E. Mamikonyan
This paper presents a power consumption estimation algorithm for static analysis. IR drop is being calculated for each separated node, which makes this algorithm favorable for IR drop calculation on infinite power network. The power consumption is being calculated using random walk algorithm, which includes Monte Carlo simulation method for increasing accuracy of estimation. For power mesh with 150 k power nodes, total IR drop cal

Design and Implementation of a New Multilevel Inverter Employing Reduced Components

Cathrine E. S. Feloups, Essam E. M. Mohamed
This paper focuses on an implementation of new topology which can synthe-size multi-level output voltage at the load terminals. The proposed inverter consists of two main parts; level generation part and polarity generation part. Level generation part is responsible for generating voltage levels at its end while; polarity generation part is a traditional H-bridge which is used to provide inversion of the output

Harmonic Investigation of Compact Fluorescent Lamps Low Energy Consumption Lamps of Cameroonian Market

S. Perabi Ngoffe, S. Ndjakomo Essiane, Florence Offole, Ghislain Mengata Mengounou, Adolphe Moukengue Imano, Onambele Onambele
This article presents a study of compact fluorescent lamps (CFLs) low energy consumption lamps found in the Cameroonian market. The current obtained in the experimental setup has been analyzed in Matlab Simulink. The results obtained show that the THD of different lamps does not respect the standard IEC-61000-3-2. These values increase with the power of lamps. Spectral analysis of these lamps

Elaboration and Performance Analysis of a Bio-Based Insulating Liquid from Castor Oil for Power Transformers

Emeric Tchamdjio Nkouetcha, Ghislain Mengata Mengounou, Adolphe Moukengue Imano
The research for new mineral oil substitutes focuses on vegetable oils known for their biodegradability and low toxicity. This paper focuses on the development and analysis of physicochemical and dielectric properties of a bio-based insulating liquid from castor oil. Castor oil is an inedible tropical resource. It has a good annual oil yield and is widely available in developing countries. Cold pressing of castor seeds is the most
