Rekindles and false alarms are unusually high in the Portuguese wildfire management system, representing a high burden on suppression resources in particular, and fire management resources in general. In 20,049 occurrences that the suppression system handled in the summer of 2010, 12.5% were false alarms and 15.0% were rekindles. We present a discreteevent simulation model of a wildfire suppres...

We report a study that examines performance of pilots flying a simulated UAV in a highfidelity environment while using different types of perfect and imperfect automation aids. Fiftysix student pilots carried out simulated UAV missions containing a 3D view of terrain, a 2D topdown navigational map, system parameter gauges, and a message box. Trajectory and manipulation of a 3D camera was contro...

In a study/recognition paradigm, new words at test were recombinations of studied syllables (e.g. BARLEY from BARTER and VALLEY), shared one syllable with studied words, or were completely new. False alarm rates followed the gradient of similarity with studied items. Event-related potentials to the three classes of false alarms were indistinguishable. False alarms elicited different brain activ...

Modeling text document similarity is an important yet challenging task. Even the most advanced computational linguistic models often misjudge document similarity relative to humans. Regarding the pattern of misjudgment between models and humans, Lee and colleagues (2005) suggested that the models’ primary failure is occasional underestimation of strong similarity between documents. According to...

This study assesses the potential influence of global navigation satellite system (GNSS) radio occultation (RO) data assimilation on forecast skill tropical cyclone formation over western North Pacific in September–October 2019 through a regional model. Data from Constellation Observing System for Meteorology, Ionosphere, and Climate mission II are applied. The considers hits misses nine develo...

In our earlier work we have proposed and developed a methodology for the early detection of Distributed Denial of Service (DDoS) attacks. In this paper, we examine the applicability of Proactive Intrusion Detection on a considerably more complex set-up, with hosts associated with three clusters, connected by routers. Background TCP, UDP and ICMP traffic following Interrupted Poisson Processes a...

We propose that in attempting to detect whether an effect exists or not, people set their decision criterion so as to increase the number of hits and decrease the number of misses, at the cost of increasing false alarms and decreasing correct rejections. As a result, we argue, if one of two complementary events is framed as the positive response to a question and the other as the negative respo...

OBJECTIVES Alarm fatigue from high false alarm rate is a well described phenomenon in the intensive care unit (ICU). Progress to further reduce false alarms must employ a new strategy. Highly sensitive alarms invariably have a very high false alarm rate. Clinically useful alarms have a high Positive-Predictive Value. Our goal is to demonstrate one approach to suppressing false alarms using an a...
