This study analyzed the applicability of CO sensors through UL 268 unwanted alarm tests and real-scale verification tailored to domestic format. A comprehensive literature review indicated that fire test cooking nuisance results revealed fire-detection concentration suggested a real can be detected if is above 17 ppm. Accordingly, during pork belly mackerel events, which triggers frequent alarm...

Fire is one of the tragedies that cannot be predicted, besides being unwanted by community, fires are also often uncontrolled when fire has started to grow. incidents very dangerous and disrupt people's lives. Many types detection devices have developed recently minimize occurrence material losses fatalities provide a sense security for users these detectors, but there still some things need ad...

Magnetic skyrmions are nanoscale magnetic whirls that highly stable and can be moved by currents which has led to the prediction of a skyrmion-based artificial neuron device with leak-integrate-fire functionality. However, so far, these devices lack refractory process, estimated crucial for neuronal dynamics. Here we demonstrate biskyrmion-based overcomes this insufficiency. When driven spin-or...

Repeating spatiotemporal spike patterns exist and carry information. Here we investigate how a single neuron can optimally signal the presence of one given pattern (localist coding), or of either one of several patterns (distributed coding, i.e. the neuron’s response is ambiguous but the identity of the pattern could be inferred from the response of multiple neurons). Intuitively, we should con...

introduction the fire services play a key role in safety issues for any country. the operations of the services have a high visibility since the public is aware of its own vulnerability and possibly vital reliance on the service. firemen and women are rightly admired, particularly as their intervention may carry a risk to their own lives. more generally, this service comes at a considerable cos...

Background: Fire and explosion hazards are extremely important in processing units. This study was performed to identify the risk centers, the potential damage caused by fire and explosion, and the days of production cessation in the processing company. Materials and Methods: The present qualitative case study was conducted using Dow’s index in 2015. The fire and explosion hazard index...
