Contemporary Practice

Analysing the development of the concept of non-state parties to an armed conflict from the writings of philosophers in the eighteenth century through international humanitarian law (IHL) treaty law to contemporary practice, three threads can be identified. First, as pointed out by Rousseau almost two and a half centuries ago, one basic principle underlying the laws of war is that war is not a relation between men but between entities. Accordingly, the lawful objective of parties cannot be to harm opponents as individuals but only to overcome the entity for which the individual fights. This necessitates that any party to an armed conflict is a collective, organized entity and not a loosely connected group of individuals. Second, de Vattel already stressed that civil war is fought between two parties who ‘acknowledge no common judge’ and have no ‘common superior’ on earth....

Moving Speed

In the industrial environment, Autonomous Guided Vehicles (AGVs) generally run on a planned route. Among trajectory-tracking algorithms for unmanned vehicles, the Pure Pursuit (PP) algorithm is prevalent in many real-world applications because of its simple and easy implementation. However, it is challenging to decelerate the AGV’s moving speed when turning on a large curve path. Moreover, this paper addresses the kidnapped-robot problem occurring in spare LiDAR environments. This paper proposes an improved Pure Pursuit algorithm so that the AGV can predict the trajectory and decelerate for turning, thus increasing the accuracy of the path tracking. To solve the kidnapped-robot problem, we use a learning-based classifier to detect the repetitive pattern scenario (e.g., long corridor) regarding 2D LiDAR features for switching the localization system between Simultaneous Localization And Mapping (SLAM) method and Odometer method. As experimental results in practice, the improved Pure Pursuit algorithm can reduce the tracking error while performing more efficiently. Moreover, the learning-based localization selection strategy helps the robot navigation task achieve stable performance, with 36.25% in completion rate more than only using SLAM. The results demonstrate that the proposed method is feasible and reliable in actual conditions.

Abstract For a unitary unramified genuine principal series representation of a covering group, we study the associated R-group. We prove a formula relating the R-group to the dimension of the Whittaker space for the irreducible constituents of such a principal series representation. Moreover, for certain saturated covers of a semisimple simply connected group, we also propose a simpler conjectural formula for such dimensions. This latter conjectural formula is verified in several cases, including covers of the symplectic groups.
