A matheuristic for the traveling salesman problem with positional consistency constraints
International Transactions in Operational Research, EarlyView.Abstract We propose a matheuristic for the traveling salesman problem with positional consistency constraints, where we seek to generate a set of routes with minimum total cost, in which the nodes visited in more than one route (consistent nodes) must occupy the same relative position in all routes.

International Transactions in Operational Research, EarlyView.Abstract This research evaluates the effectiveness of a hybrid crowdshipping system that integrates occasional drivers with traditional delivery services (OD+TD) to improve the efficiency of freight distribution. By implementing the team orienteering problem with occasional drivers model, we develop a mathematical model and an agile optimization ...

Unilateral Action on Climate Change and the Moral Obligation to Take Leadership
Journal of Social Philosophy, EarlyView.ABSTRACT We claim that a moral obligation to take climate leadership by means of unilateral mitigation depends on the existence of a plausible follow‐the‐leader mechanism whereby unilateral mitigation by some increases the probability of sufficient mitigation by others to avert catastrophic climate impacts.

Influence of Chronotype on Cycling Performance in Simulated 20‐km Time Trials—A Pilot Study
Journal of Sleep Research, EarlyView.Evening‐type athletes show improved cycling performance later in the day, whilst morning types peak earlier. These differences appear linked to variations in mental readiness and sleepiness, highlighting the importance of considering chronotype in performance planning.

, 2010 The purpose of this study is to make an electrical bicycle. As this bike has an electrical motor, it will not be used as a sport method, the main idea is to use it as a public transport so people can move from side to side of the city without traffic, without pollution and without getting tired. Once selected the purpose of the bicycle, it is necessary
