In many engineering and industrial processes, the entropy production destroys the available energy in the system.
The second law of thermodynamics is more reliable than the first law of thermodynamics because of the limitation of the efficiency of the first law in heat transfer engineering systems [14].
Entropy generation minimization is applied in various thermal engineering systems such as air separators, reactors, chillers, fuel cells, thermal solar, chemical and electrochemical.
The key findings of the article are concluded at the end of the manuscript.
The Prandtl number is chosen the values ranging from which are the most encountered fluids used in plasma physics, engineering and industries.

Robustness based structural design: an integrated approach for multi-hazard risk mitigation Dubina Dan1,a and Dinu Florea2, b 1The ”Politehnica” University of Timisoara, Faculty of Civil Engineering, Timisoara, Romania 2The ”Politehnica” University of Timisoara, Faculty of Civil Engineering, Timisoara, Romania adan.dubina@ct.upt.ro, bflorea.dinu@ct.upt.ro Keywords: extreme loading, risk, robustness, column loss, ductility, steel structures.
However, this should not be assumed apriori, as there are also differences between these hazards and their effects on structures, for instance, the rotation demand of connections associated with the loss of key structural elements.
However, for progressive collapse analysis of the main structural system, the behavior of the material can be considered rate independent.

Modeling and Optimization a Production/Maintenance Integrated Planning Ghita Ettaye1, a *, Abdellah El Barkany1,b and Ahmed El Khalfi1,c 1 Mechanical Engineering Laboratory, Faculty of Science and Techniques, Sidi Mohamed Ben Abdellah University, Fez, Morocco.
Production Plan In the literature, as a first solution of production planning we found the MRP I (Material Requirement Planning) that started between 60 and 70 years ago [3] but this model did not consider the constraint of resources capacity.
Indeed, communication and collaboration between the maintenance actions and the production operations are the main keys to success organizing and planning a production system.

Introduction Current manufacturing environment can be characterized in terms of many factors but the key one for companies confronting the challenge of remaining competitive in an era of globalization is undoubtedly the capability of fast and accurate decision making, especially so in the mass customized production/services domain.

Upscaling the Quality of Service (QoS) and improving the network performance in a dynamic and resource-constrained network like the WBAN is key to sustaining the operability of the network.
Additionally, the implementation incorporates the use of Selenium, a material with a Seebeck coefficient (S) of 900μV/°C.

Stiffness of the interface material has to be high enough to limit mutual penetration of the volumes and low enough to preserve convergence of the model.
It is linearly dependent on elastic modulus of the material and oppositely dependent on element size [5].
