In this letter, we investigate a UAV-enabled communication system, where UAV is deployed to communicate with the ground node (GN) in presence of multiple jammers. We aim maximize energy efficiency (EE) by optimizing its trajectory, subject UAV's mobility constraints. However, formulated problem difficult solve due non-convex and fractional form objective function. Thus, propose an iterative alg...

A novel and sustainability-oriented approach to the design of large-aperture iron-dominated magnets is proposed, focusing on its application charged particle momentum detection in high-energy experimental physics. As compared classical techniques, a broader number goals constraints taken into account, considering jointly performance, minimization both electrical power magnet size, electromagnet...

Concrete made with Portland cement is by far the most heavily used construction material in world today. Its success stems from fact that it relatively inexpensive yet highly versatile and functional widely available raw materials. However, many environments, concrete structures gradually deteriorate over time. Premature deterioration of a major problem worldwide. Moreover, production energy-in...

Several aspects must be considered in the design of rolling bearing cages. One most important considerations relates to studying and developing a stationary approach for solving problems heat mass transfer during convection. In this context, paper proposes, among other achievements, development validation model generation that is used, as basis an energy-efficient cage context roller bearings a...

Abstract Outdoor lighting solutions are a key to safe urbanization. It is important that assessment of done at the design stage keeping in mind crucial parameters like environment friendly design, light pollution, and energy efficiency. These met by meticulously using standards each every design. This process further naturally inclines realizing sustainable for future generations. In this paper...
