Unveiling uncertain forces in second-order driven oscillators via internal model: A discrete-time feedback by R. Femat, C. Jiménez-gallegos

“…The main idea is to construct an internal model of the nonlinear system and design a discretetime feedback in such way that the model/system differences be stabilized at origin. In principle, if the internal model tracks the trajectory of the nonlinear system, then the uncertain force is recovered by the stabilizing command.…”

UUV Autonomous Decision-Making Method Based on Dynamic Influence Diagram by Hongfei Yao, Hongjian Wang, Ying Wang

“…Then, based on the threat assessment results for the UUV, the utility of each decision-making plan in the decision-making nodes is inferred and predicted. Subsequently, the principle of maximum expected utility is used to select an optimal autonomous decision-making plan. …”

The current situation of intercountry adoption in Spain by Juan Pedro Díaz Senés

“…As a result of this study, it is observed that, beyond the current circumstances brought about by the COVID-19 crisis, this institution currently has a residual weight that is increasingly in line with the principle of subsidiarity, recognized by the Convention of 29 May 1993 on Protection of Children and Cooperation in Respect of Intercountry Adoption. …”

Solution to the Problem of a Mass Traveling on a Taut String via Integral Equation by M. Ferretti, A. Luongo

“…The equations governing the moving boundary problem are derived via a variational principle, in which the geometric compatibility between the point mass and the string is enforced via a Lagrange multiplier, having the meaning of transverse reactive force. …”

Decision-Making Research on Tour Lines of Tourist-Dedicated Train Based on Vague Sets and Prospect Theory by Yuanding Cui, Changxi Ma

“…Tourist-dedicated train is the product of the combination of railway transportation and tourism, and its tour line selection includes the selection of nodes and lines. Based on the principle of decision-making, taking technical factors, tourism factors, regional economic factors, and passenger flow factors as criteria, this paper analyzes the decision-making indices affecting the tour line and establishes the decision-making index system. …”
