A Galton–Watson process with a threshold
Abstract In this paper we study a special class of size dependent branching processes. We assume that for some positive integer K as long as the population size does not exceed level K, the process evolves as a discrete-time supercritical branching process, and when the population size exceeds level K, it evolves as a subcritical or critical branching ...

An improved infrared image processing method based on adaptive threshold denoising
This paper combines the image adaptive threshold denoising algorithm and performs double threshold mapping processing to the infrared image, which effectively reduces the influence of these phenomena to the infrared image and improves the quality of the ...

On identification of the threshold diffusion processes [PDF]
We consider the problems of parameter estimation for several models of threshold ergodic diffusion processes in the asymptotics of large samples. These models are the direct continuous time analogues of the well-known in time series analysis threshold autoregressive (TAR) models.

Aiming at the problem that the signals received by MEMS vector hydrophones are mixed with a large amount of external environmental noise, and inevitably produce baseline drift and other distortion phenomenons which made it difficult for the further ...

Signal processing algorithm of ship IMU accelerometer based on wavelet theory
Objectives Based on an analysis of the signal noise characteristics of an inertial measurement unit (IMU) accelerometer, the noise was studied in the wavelet domain.Methods In order to solve the limitations of the traditional Fourier filtering method for

Continuous Wavelet Transform and Hidden Markov Model Based Target Detection [PDF]
Standard tracking filters perform target detection process by comparing the sensor output signal with a predefined threshold. However, selecting the detection threshold is of great importance and a wrongly selected threshold causes two major problems ...

Thermal Impact on Spiking Properties in Hodgkin-Huxley Neuron with Synaptic Stimulus
The effect of environmental temperature on neuronal spiking behaviors is investigated by numerically simulating the temperature dependence of spiking threshold of the Hodgkin-Huxley neuron subject to synaptic stimulus.

ABSTRACT Background Transfusion‐related iron overload (TRIO) is a late effect of therapy impacting survivors of childhood cancer and hematopoietic stem cell transplantation (HSCT) who receive frequent packed red blood cell (pRBC) transfusions. Surprisingly, there are no accepted guidelines to assist providers in identifying and treating at‐risk ...

RECEPTIVE AND PRODUCTIVE VOCABULARY ACQUISITION: EXAMINING PROCESSING TIME AND MEMORY THRESHOLD
: In the present research a picture card-based vocabulary study method was used to determine the pace of learner acquisition in terms of both receptive and productive knowledge. Fifty-eight first-year Japanese university students in two classes were used
