The exponential stability of a class of discrete time linear systems with a finite state Markov chain form process and the impulsive jump at switching moments is studied. Based on the average dwell time concept, it is shown that if the average dwell time and the ratio of the expectation of the activation time with stable subsystems to the expectation of the activation time with unstable subsyst...
In previous work, electromagnetic matchedeld processing was proposed for estimating aircraft altitude with over-the-horizon radar using a single radar dwell. Although this approach exploits the altitude dependence of unresolved multipath returns in complex delay-Doppler space, its performance su ers in situations where the coherent integration time (CIT) of the radar is short. To overcome this ...
To develop an easy independent patient-specific quality assurance (QA) method using a benchmark plan for high-dose-rate intracavitary brachytherapy for cervix cancer, we conducted benchmark treatment planning with various sizes and combinations of tandem-ovoid and tandem-cylinder applications with 'ideal' geometry outside the patient. Two-dimensional-based treatment planning was conducted based...
The Uncanny Valley Hypothesis (Mori, 1970) predicts that perceptual difficulty distinguishing between a humanlike object (e.g., lifelike prosthetic hand, mannequin) and its human counterpart evokes negative affect. Research has focused on affect, with inconsistent results, but little is known about how objects along the hypothesis' dimension of human likeness (DHL) are actually perceived. This ...
OBJECTIVES To determine the incidence, risk factors for and outcomes of Staphylococcus aureus bacteraemia (SAB) associated with peripheral intravenous catheters (PIVCs). DESIGN, SETTING AND PATIENTS A review of prospectively collected data from two tertiary health services on all health care-associated SAB episodes occurring in adults aged > 17 2013s from January 2007 to July 2012. MAIN OUT...
