Experimental Study of a Quadratic Boost: The Cascaded Connected Single Switch
Prince Abdoul Aziz Honadia; Bernard Zouma;Adama Ouédraogo;Fabé Idrissa Barro
The quadratic boost is studied under its real model. The equations, of the continuous conduction mode, descriptive of this model are established. From these equations, the expressions of the voltage gain and the efficiency are extracted. These two quantities are plotted as a function of the duty cycle in order to appreciate them in different o(...)

Physical and mechanical characterization of aggregates in Burkina Faso: implications for use as endogenous knowledge in civil engineering
Abdoul Aziz Ouiminga, Adélaïde Lareba Ouedraogo, Patrice Kouraogo, Mohamed Yerbanga, Sié Kam
Aggregates are the world's most widely exploited resource, surpassing even fossil fuels. They are mainly used for concrete production. On the one hand, due to restrictions on the use of river sand in some parts of the world to conserve river beds, demand for alternative fine aggregates in the construction sector has increased considerably. The(...)

Investigating the Impact of Base Heating and External Electric Field on PV Cell Performance under Intense Illumination
Boubacar Soro, Guy Serge Tchouadep, Esso-Ehanam Tchedre Kpeli, Ousmane Souliga, Adama Ouedraogo, Issa Zerbo, Martial Zoungrana
The characterization of the performances of a PV cell is linked to intrinsic factors of this cell. It is therefore important for us to identify the favorable or unfavorable conditions that affect the performance of PV cells. It is from this
perspective that it seems judicious to us to study the simultaneous influence of the heating of the bas(...)

Numerical Models and Methods of Atmospheric Parameters Originating in the Formation of the Earth’s Climatic Cycle
Wend Dolean Arsène Ilboudo1*, Kassoum Yamba1, Windé Nongué Daniel Koumbem2, Issaka Ouédraogo1
Atmospheric models are physical equations based on the ideal gas law. Applied to the atmosphere, this law yields equations for water, vapor (gas), ice, air, humidity, dryness, fire, and heat, thus defining the model of key atmospheric parameters. The distribution of these parameters across the entire planet Earth is the origin of the formation(...)
