Unmanned aerial vehicles (UAVs) have the characteristics of high mobility and wide coverage, making them widely used in search, other fields. In these applications, UAV often has limited energy. Therefore, planning a time-efficient coverage path for energy-constrained to cover area interest is core issue. The existing algorithms assume that moves at constant speed, without taking into account c...

Language planning, in one way or another, is as old as human civilization. Every time that one polity  invaded  the  territory  of  another,  the  language  of  the  conqueror  was  imposed  on  the conquered. The Romans imposed their language across the civilized world as they  knew it. In the  21st  century,  the  practice  of  language  planning  has  become  increasingly  sophisticated. Eng...

People tend to behave inconsistently over time due an inherent present bias. As this may impair performance, social and economic settings need be adapted accordingly. Common tools reduce the impact of time-inconsistent behavior are penalties prohibition. Such called commitment devices. In recent work Kleinberg Oren [6, 7] connect design prohibition-based devices a combinatorial problem in which...
