This article proposes a finite-time disturbance observer-based modified super-twisting algorithm (FDO-STA) for disturbed high-order integrator-chain systems under matched and mismatched disturbances. We first design observer estimation, in which we show the convergence of estimation errors to zero. Second, by employing estimates disturbances their derivatives, new dynamic sliding surface is der...

Prikaz primera: 71-letna bolnica s cervikalnim nekrozantnim fasciitisom je po operaciji dobila težave z disfagijo. Radiološka in fiberoptična obravnava sta pokazali aspiriranje in hiposenzibiliteto glotisa in supraglotisa. Poleg nezadostnega dviga grla pojasnjujemo disfagijo še s senzoričnim deficitom supraglotisne sluznice, ki mu sledi odsotnost addukcije glasilk med požiranjem. Senzorični def...

Pseudoaneurysms of the superficial temporal artery (STA) are uncommon vascular lesions. Approximately 75% of them result from blunt trauma. Other etiological factors include penetrating wounds, iatrogenic trauma such as hair grafting and neurosurgical procedures. Thorough history and physical examination are often sufficient to make the diagnosis. Imaging studies are recommended for closer morp...

In the field of WiFi sensing, as an alternative sensing source channel state information (CSI) matrix, use a beamforming feedback matrix (BFM) that is right singular CSI has attracted significant interest owing to its wide availability regarding underlying systems. IEEE 802.11ac/ax standard, station (STA) transmits BFM access point (AP), which uses for precoded multiple-input and multiple-outpu...

The combustion of fuels, aside from their state concentrations (solid, liquid, gas), always occur in the gas phase. Next gas phase which is the mixture of the fuel and air or the fuel and oxygen, as well as of the fuel and gases containing oxygen can occurs in the form premixed homogeneous or not premixed heterogeneous. Processes of the combustion of liquid fuels and solid are more complicated ...

Abstract In this article, silicotungstic acid (STA)-loaded metal–organic framework (MOF)-derived composites (C-STA@ZrO 2 ) were successfully synthesized by simple strategies. X-ray diffraction, Fourier transform infrared, scanning electron microscopy, energy-dispersive X-ray, N physisorption, UV-vis diffuse reflection spectroscopy, and photoelectron spectroscopy techniques used to characterize ...

BACKGROUND Complications of clandestine abortions increase with gestational age. The aim of this study was to identify complications of second trimester clandestine abortions (STA) and those of first trimester clandestine abortions (FTA). METHODS This retrospective descriptive study was conducted between March 1st and August 31st, 2012 in the University Teaching Hospital and the Central Hospi...

The present retrospective study was performed to evaluate the clinical outcome, as well as post-operative collateral formation and revascularization patterns in combined bypass. Surgical revascularization has been the mainstay of treatment for moyamoya patients. A total of 76 hemispheres from 64 moyamoya patients undergoing combined superficial temporal artery-middle cerebral artery (STA-MCA) a...
