Mass or heat transfer inside a spherical gas bubble at low to moderate Reynolds number [PDF]
, 2013 Mass (or heat) transfer inside a spherical gas bubble rising through a stationary liquid is investigated by direct numerical simulation. Simulations were carried out for bubble Reynolds number ranging from 0.1 to 100 and for Péclet numbers ranging from 1

Two-Dimensional Convolutional Recurrent Neural Networks for Speech Activity Detection [PDF]
, 2019 Speech Activity Detection (SAD) plays an important role in mobile communications and automatic speech recognition (ASR). Developing efficient SAD systems for real-world applications is a challenging task due to the presence of noise.

Constructive Approximation by Superposition of Sigmoidal Functions
Analysis in Theory and Applications, 2013 In this paper, a constructive theory is developed for approximating func- tions of one or more variables by superposition of sigmoidal functions. This is done in the uniform norm as well as in the L p norm. Results for the simultaneous approx- imation, with the same order of accuracy, of a function and its derivatives (whenever these exist), are ...

Turning on the alarm: the neural mechanisms of the transition from innocuous to painful sensation [PDF]
, 2011 The experience of pain occurs when the level of a stimulus is sufficient to elicit a marked affective response, putatively to warn the organism of potential danger and motivate appropriate behavioral responses.

Some properties of the Blumberg's hyper-log-logistic curve
Biomath, 2018 The paper considers the sigmoid function definedthrough the hyper-log-logistic model introduced by Blumberg. We study the Hausdorff distance of this sigmoid to the Heaviside function, which characterises the shape of switching from 0 to 1.
