This paper presents a super-twisting-based sliding mode control method for the formation problem of multi-robot systems.The multiple Ball Bearing robots contain plenty of uncertainties and disturbances.Such a control method has two adaptive gains that can contribute to the robustness and improve the response of the formation maneuvers despite these
As for the wild animals, their diet components are always changed, so that we have to monitor such changes by analyzing the modification of TROUSERS URBAN COTTON intestinal microbial community.Such effort allows us to amend their conservation strategies and tactics accordingly so that they are able to appropriately adapt to the new environment and
Nanotubes were prepared by self-assembly of the copolymer using co-solvent evaporation method.The biocompatibility of the nanotubes was assessed in comparison with spherical micelles and filomicelles prepared from poly(ethylene glycol)-poly(L-lactide-co-glycolide) (PEG-PLGA) and poly(ethylene glycol)-poly(L-lactide) (PEG-PLA), respectively.Several
This study continued the in vitro screening of locally available ruminant feedstuffs for optimum nutrient composition and low methane (CH4) production in Ethiopia.The best bet feeds from the in vitro study, hereafter called the test feeds, include dried leaves of Acacia nilotica, Ziziphus spina-christi, and brewery spent grains (BSG).The study invo
