This paper presents a novel fixed time sliding mode disturbance observer (FTSMDO) based second-order fixed time sliding mode control (FTSMC) for small scale unmanned helicopter to do hover Goalie - Pants - Junior operations in the presence of external disturbances.Sliding mode control is insensitive to matched uncertainties but sensitive to mismatc

Invisibility cloaking based on transformation optics has brought about unlimited space for reverie.However, the design and fabrication of transformation-optics-based cloaks still remain fairly challenging because of the complicated, even extreme, material prescriptions, including its meticulously engineered anisotropy, inhomogeneity and singularity

Background Neonates undergo many uncomfortable, invasive minor procedures during their first hospital stay.Nonpharmacological interventions may provide valuable SPORTS BRA alternatives for pain relief in neonates during minor procedures.Objective To compare the analgesic effect of orally administered breast milk vs.non-nutritive sucking (NNS) in ne

As part of the SAFElevee project Delft University of Technology collabored with Flanders Hydraulics Research, and Infram B.V.in the preperation and execution of a full scale embankment breach experiment in November 2015.This breach experiment was performed on an 3.5m high embankment with a sand core and clay outer layer situated along the tidal riv

Abstract Varroa mites, notorious for parasitizing honeybees, are generally classified as Varroidae.Their extremely modified morphologies and behaviors have led to debates regarding their phylogenetic position and classification as an independent family.In this study, two different datasets were employed to reconstruct the phylogenies of Varroa mite
