Children aged 3, 5, and 8 years received training on a temporal bisection task, with standard short and long durations being presented as visual stimuli lasting 1 and 4 s or 2 and 8 s. Nonstandard comparison stimuli were spaced linearly between the standards. Psychophysical functions showed increasing proportions of “long” responses (responses appropriate to the long standard) with increasing s...

hypothermia generates potentially severe complications in operating or recovery room. forced air warmer is effective to maintain body temperature. extremely low frequency electromagnetic field (elf-emf) is harmful to human body and mainly produced by electronic equipment including convective air warming system. we investigated elf-emf from convective air warming device on various temperature se...

background and purpose: the objective of medical education is to train competent and qualified workforce in order to provide services in various health environments. one of the important objectives of operating room students is to train workforce who can involve in patient’s health and recovery. training these students should cause clinical ability and independent decision making during surgery...

This article proposes a novel mathematical approach to deal with cyberattacks (CAs) impacting on modernized microgrid's (MMG) tertiary control. MMGs use many entities based voltage-source converters form the fully integrated power and energy system (FIPES). Having such for necessitates engineers considering cybersecurity addressing its effects from beginning of designing building systems. Using...

We present a homotopy continuation method (HCM) for finding multiple operating points of nonlinear circuits composed of devices modelled by using piecewise linear (PWL) representations. We propose an adaptation of the modified spheres path tracking algorithm to trace the homotopy trajectories of PWL circuits. In order to assess the benefits of this proposal, four nonlinear circuits composed of ...

This paper describes a terrain-aided navigation system that employs points of maximum curvature extracted from laser scan data as primary landmarks. A scale space method is used to extract points of maximum curvature from laser range scans of unmodified outdoor environments. This information is then fused with odometric information to provide localization information for an outdoor vehicle. The...

In several research domains concerned with classification tasks, curves like ROC are often used to assess the quality of a particular model or to compare two or more models with respect to various operating points. Researchers also often publish some statistics coming from the ROC, such as the socalled break-even point or equal error rate. The purpose of this paper is to first argue that these ...

Experimental tests in prototype are necessary to understand the dynamic behaviour of the machine during different operating points. Hydraulic phenomena as well as its effect on the structure need to be studied in order to avoid instabilities during operation and to extend the lifetime of the different components. For this purpose, a complete experimental study of a large Francis turbine prototy...

Editor’s key points † Perception of patient safety is an important component of organizational structure essential to quality improvement, but is complex and difficult to study. † This study examined the influence of environment (operating theatre or intensive care unit) and discipline on organizational factors (latent risk factors) in four university hospitals using a new survey instrument. † ...
