The optimal distance and driving strategy of multiple jeeps problem are known. We consider multiple jeeps problem with container restriction, which is more complicated in the proof of feasibility and optimality of a driving strategy. We investigate when it can achieve the same optimal distance as without restriction.Based on the non-restricted optimal distance, a new driving strategy is proposed. We provide the necessary and sufficient condition to ensure the feasibility of the strategy, and obtain the maximal feasible distance.展开更多

This nonmainstream structure of communication can be conceived as a type of counterargument to international border policies. In this essay, I examine how Bartolo Fuentes’s <em>Caminata del Migrante</em> post digitally informed migrant decision making processes, enforced migrant solidarity, and spurred a digital heterotopia providing a back and forth sharing of opinions and information between migrants, political actors, advocacy groups, and the press.展开更多

If everyone respected and offered sacrifices to the gods, and followed all the caravan rules, then they the gods would protect them.展开更多

文摘Jeep problem is a kind of model of logistics in extreme situation, which has application in exploration and aircraft problems. The optimal distance and driving strategy of multiple jeeps problem are known. We consider multiple jeeps problem with container restriction, which is more complicated in the proof of feasibility and optimality of a driving strategy. We investigate when it can achieve the same optimal distance as without restriction.Based on the non-restricted optimal distance, a new driving strategy is proposed. We provide the necessary and sufficient condition to ensure the feasibility of the strategy, and obtain the maximal feasible distance.
文摘Social media have become an important communication tool and backstage for the dissemination of information for Honduran migrants seeking political asylum and international refugee status in the United States at the Otay Mesa Port of Entry.

In this essay, I examine how Bartolo Fuentes’s <em>Caminata del Migrante</em> post digitally informed migrant decision making processes, enforced migrant solidarity, and spurred a digital heterotopia providing a back and forth sharing of opinions and information between migrants, political actors, advocacy groups, and the press.
