We focus on the dynamics of a small particle near the Lagrangian points of the Sun-Jupiter system. To try to account for the effect of other planets, such as Saturn or Uranus, we develop specific models based on the numerical computation of periodic and quasi-periodic (with two frequencies)...
address to this conference — mainly as an opportunity to raise certain questions, fundamental to problems of solar-system research, without moral obligation to provide their answers (and in the hope that papers presented at subsequent sessions of our congress may contribute towards their clarification...
The sheets are charged by induction, charging them with opposites charges to a charge density of magnitude 20.2 nC/m2. The separation of the sheets is tripled while the charge density is kept the same. Determine the change in the electric field and the potential difference between the plates...

Power in Circuits: Study with Video Lessons, Practice Problems & Examples 54 problems 1PRACTICE PROBLEM Batteries store energy that is used in diverse ways. The starter motor in a four-cylinder engine draws 130 A at 12 V. If the starting process lasts 2.5 s, determine the energy supplied. ...
The former case is the optimization of a mechanical structure in the nuclear fuel bundle and the last case is the optimization of the cost function of a cogeneration system using PSO in a hybrid optimization. Finally, a conclusion is presented. Keywords PSO algorithm hybrid methods nuclear fuel ...
Attention is given to all the mechanisms currently known which might have been responsible for the melting of the moon. A comparison is conducted of the terrestrial planets and the moon, taking into account the conditions in the early solar system as a function of time. The assumption is made...

Due to the nonlinear multi-objective nature of these problems, the traditional methods are not suitable approaches for solving large-scale power system operation dilemmas. The integration of optimization algorithms into power systems has been discussed in several textbooks, but this is the first to ...
