Cost-Effective Monitoring of the Fuel Air Equivalence-Ratio with a Lambda Sensor and a Microcontroller in a Downdraft Biomass Gasifier
Jean Fidele Nzihou, Salou Hamidou, Ousmane Zoundi, Frederic Ouattara, Bila Gerard Segda
The operation of biomass treatment devices such as gasifiers is based on the
control of key parameters that play an important role in product formation.
These include: temperature, excess oxygen, relative humidity and biomass
composition. This work focuses on excess oxygen and temperature. Unfortunately, flue gas oxygen analyzers are ex(...)

Study of The Influence of Storage Media on the Thermo-mechanical Behavior of Concrete and Cement Blocks
Benjamin Kiema , Ousmane Coulibaly and Emmanuel Ouedraogo
Once all construction materials have been formulated, it is necessary to find a suitable environment in which to store them before using them in the building. Generally speaking, in developing countries, materials are not preserved under the real conditions of temperature and humidity and are exposed to often severe climatic conditions. This h(...)

Experimental and Numerical Study of the Effect of Cloud Cover on the Electrical Performance of Photovoltaic Plants
Kayaba Haro1,2# , Abdoulaye Compaore1 , Abdoulye Kabore2 , Kombassere Jean Gérard2 , Sayouba Sandwidi2 , Christian Tubreoumya Guy2 , Souleymane Sinon3 , Bere Antoine2 & Sanogo Oumar
The production of electricity from the sun mainly consists of transforming the light emitted by the
sun into electrical energy through photovoltaic cells. This production varies proportionally with the
light that illuminates the solar photovoltaic module. According to the literature, we noted that during
the period of cloudy passage, the(...)

Mobility and Decoherence of Bipolaron in Transition Metal Dichalcogenides Pseudodot Quantum Qubit
C. Kenfack-Sadem, J. V. Nguepnang, S. Nse Biyoghe, N. Addison, V. D. Bokoyo Barandja, Issa Zerbo
In this work, we investigated the mobility and decoherence of bipolaron in transition metal dichalcogenides pseudodot quantum qubit using the Huybrecht method. We investigated the mobility of the bipolaron and the ground and first excited state energies and highlighted that the qubit can be formed in superposition state of the system. The deco(...)

Influence of heavy fuel oil on the thermo-physical an erodibility properties of earthen materials
Ohindemi G. Yameogo, Donzala D. Some, Souleymane Ouedraogo, Philbert Nshimiyimana, Dieudonné J. Bathiebo
This study focuses on the use of heavy fuel oil in construction in Burkina Faso. Mixed with silty and/or clay soil, it is used as a coating to reinforce the walls of raw soil constructions which are very sensitive to water. The interest of this paper is to shed light on the thermomechanical and above all water effects of heavy fuel oil on a sa(...)

Monitoring the Air-fuel Ratio (AFR) of a Biomass Gasification Process with an Arduino Uno 3 and a Narrow Band Lambda Oxygen Sensor
Hamidou Salou a*, Nzihou Jean Fidele b , Zoundi Ousmane b , Ouattara Frederic b and Segda Bila Gerard c
The Air-Fuel Ratio is one of the keys parameters for driving the gasification process. Monitoring of oxygen percentage in flue gases is one of various ways of controlling efficiency and emissions of industrial combustion. Biomass gasification is a thermochemical degradation of the biomass that is accomplished with the Air-Fuel Ratio less than(...)
