This work presents a mission concept for in-orbit particle collection sampling and exploration missions towards Near-Earth asteroids. Ejecta is generated via small kinetic impactor two possible strategies are investigated: collecting the along anti-solar direction, exploiting dynamical features of L2 Lagrangian point or them while spacecraft orbits asteroid before they re-impact onto surface. C...

The selection of appropriate work center is one of the most critical decision in process planning of a successful production environment. In this study, a user-friendly decision support system is proposed for work center selection. This system guides the decision-maker in selecting work-center from available work-centers via effective algorithms, such as the Analytic Hierarchy Process (AHP). .T...

Amaranth (Amaranthus spp.) is an underutilized crop increasing in popularity as a grain and leafy vegetable. It rich protein, minerals, vitamins, adapts well to range of production systems. Currently, the lack improved cultivars limits use crop. Breeding-improved requires access large collections amaranth biodiversity stored genebanks. The task searching such vast for traits interest can be eas...

ABSTRACT Handroanthus impetiginosus is a Brazilian native tree threatened by illegal logging that needs conservation strategies. Due to the need obtain seeds of high genetic and physiological quality, this study aimed select mother trees, aiming at installation Seed Collection Areas H. impetiginosus. Therefore, diversity quality from 63 individuals natural population in Rio Grande do Norte, Bra...
