We model the propagation of neural activity through a feedforward network consisting of layers of integrate-and-fire neurons. In the presence of a noisy background current and spontaneous background firing, firing rate modulations are transmitted linearly through many layers, with a delay proportional to the synaptic time constant and with little distortion. Single neuron properties and firing ...

Abstract—We propose an analog integrated circuit that implements a resonate-and-fire neuron (RFN) model based on the Volterra system. The RFN model is a simple spiking neuron model that exhibits dynamic behavior observed in biological neurons, such as fast subthreshold oscillation, post-inhibitory rebound, and frequency preference. The RFN circuit was derived from the Volterra system to mimic s...

The discrimination between two spike trains is a fundamental problem for both experimentalists and the nervous system itself. We introduce a measure for the distance between two spike trains. The distance has a time constant as a parameter. Depending on this parameter, the distance interpolates between a coincidence detector and a rate difference counter. The dependence of the distance on noise...

A project was initiated to investigate concerns regarding the application of duct smoke detectors (ASHRAE RP-1079). The objective of the research was to investigate the effects of driving forces, dilution, aging, smoke stratification, filters, and sample tube efficacy on smoke detector response. As one part of this project, a series of full-scale fire tests were conducted in a ten-story facilit...

An emergency is a deviation from planned or expected behaviour or a course of event that endangers or adversely affects people, property, or the environment. This paper reports a complete research work in accident (automobile) emergency alert situation. The authors were able to programme a GPS / GSM module incorporating a crash detector to report automatically via the GSM communication platform...

We investigate a novel class of neural stochastic resonance (SR) exhibiting error-free information transfer. Unlike conventional neural SR, where the decrease of a system's response with too much noise is associated with an increase in the baseline firing rate, here the bell-shaped SR behavior of the input-output cross correlation emerges versus increasing input noise in spite of no significant...

IoT (Internet of Things) is a concept that aims to expand the benefits continuously connected internet connectivity continuously. can be used at home as smart system for controlling electronic equipment operated by means ofinternet connection (WiFi). This IoT-based uses ESP 8266 microcontroller hardware and blynk application tool controller control. consists lamp controller, knowing humidity ro...

This paper presents experimental research findings for those involved in the early phase of fire office buildings. Class A model fires with a reaction area from 5 cm2 to 300 were chosen investigation. To mock up fire, following combustible materials typical offices used: wood pieces, heat-insulated linoleum, and cardboard. The main characteristics recorded: temperature combustion zone, heat rel...
