Realization and Experimental Study of a Forced Convection Solar Dryer
Boureima Dianda, Labayè Yves Japhet Koussoubé, Lareba Adélaïde Ouédraogo, Moctar Ousmane and Dieudonné Joseph Bathiébo
Post-harvest losses represent a significant cause of food insecurity worldwide. These losses not only affect the availability of food, but they also impact the economic stability of farmers and communities dependent on these crops. Food drying presents itself as a viable solution to reduce these post-harvest losses and ensure greater availabil(...)

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(...)

Performance Study of a Quadratic Boost Converter
Modou Badiane, Prince Abdoul Aziz Honadia, Oumar Diallo Sadio, Fabé Idrissa Barro
Energy is the driving force behind all economic and industrial development. Africa is the least advanced continent in terms of energy consumption and production. Paradoxically, it is the sunniest continent, which is why our objective is to exploit this energy potential in order to produce and use sufficient energy. To achieve this, we are carr(...)

Study of Axisymmetric Infinite Guide Lined with Locally Reacting Material without Flow Using DtN Operators
Boureima OUEDRAOGO, Emmanuel REDON
The present work proposed a new method for the modeling by the finite element
method of the acoustic propagation problems in infinite axisymmetric
cylindrical guides lined with locally reacting absorbent materials without
flow. The method deals with the development of an efficient transparent
boundary condition based on DtN operators. The(...)

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(...)

Monitoring Temperature and Humidity in Biomass Gasification Using Arduino Technology
Jean Fidele Nzihou a*, Ousmane Zoundi a, Salou Hamidou b, Bila Gerard Segda c and Frederic Ouattara a
Gasification of biomass can be done with pure oxygen or with ambient air. We have chosen gasification with ambient air in our project for costs considerations. Relative humidity (RH) of the air we used with a downdraft co-current gasifier is monitored in this paper. RH sensor used in this
paper presents a capacitor which depends on the amoun(...)

Experimental and Numerical Study of the Effect of Cloud Cover on the Electrical Performance of Photovoltaic Plants
Kayaba Haro, Abdoulaye Compaore, Abdoulye Kabore, Kombassere Jean Gérard, Sayouba Sandwidi, Christian Tubreoumya Guy, Souleymane Sinon, Bere Antoine & 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(...)

Jean Fidele Nzihou a*, Ousmane Zoundi a, Salou Hamidou b, Bila Gerard Segda c and Frederic Ouattara a
Commercial gas analyzers are not suited for long time usage and relatively too costly for
institutions in underdeveloped countries. Metal oxide sensors have emerged as simple and reliable
sensors for gases concentration measurements at an affordable cost. For gasification, carbon
monoxide, hydrogen and methane concentration must be monit(...)
