This study deals with the task assignment problem of heterogeneous unmanned aerial vehicle (UAV) system with the limited resources and task priority constraints.The optimization model which comprehensively considers the resource consumption, task completion effect, and workload balance is formulated.Then, a concept of fuzzy elite degree is proposed
The selection of appropriate geometrical characteristics of enclosure has salient influence on performance of different thermal engineering processes and devices like microelectronics, heat exchangers, power engines, boilers, solar collectors, nuclear reactors French Door Closing Bar Spring and so forth.Specifically, the triangular cavity of differ
BackgroundUpwelling systems are characterised by an intense primary biomass production in the surface (warmest) water after the outcrop of the bottom (coldest) water, which is rich in nutrients.Although it is known that the microbial assemblage plays an important role in the food chain of marine systems and that the upwelling systems that occur in
We report a Acrylic Photo Film Strip case of a 33-year-old male with a mixed germ-cell testicular tumor.Postoperative follow-up FDG-PET revealed concentration of FDG in the left inguinal area which is not tumor metastasis or local recurrence but suture reactivity granuloma.In this paper, we reviewed suture granulomas associated with false-positive
