During the granulation process of Iron ore sinter mixture, there are many factors affect the granulating effect, such as chemical composition, size distribution, surface feature of particle, and so on. Some researchers use traditional fitting calculation methods like least square method and regression analysis method to predict granulation effects, which exists big error. In order to predict it...

In this paper a critical review of gradient-based training methods for recurrent neural networks is presented including Back Propagation Through Time (BPTT), Real Time Recurrent Learning (RTRL) and several specific learning algorithms for different locally recurrent architectures. From this survey it comes out the need for a unifying view of all the specific procedures proposed for networks wit...

Evaluation of cosmic ray trajectories and penetration inside the Earth environment is mandatory for estimation flux by on-orbit detectors as well radiation damage on electronics devices biological tissues, like those astronauts onboard International Space Station. We studied impact external magnetic field calculation some parameters rigidity cut-off, a quantitative comparison among several geom...

In common buildings the soil-structure-interaction (SSI) is governed by the elastic behaviour of the building. The best conditions to see the soil effect predominate would be a dynamic rigid body movement of a massive building. For this reason measurements were carried out on an old anti-aircraft tower from World War II on typical Viennese soil conditions. The dynamic properties of the soil cou...

Cage-shaped gallium complexes with a back-shielding framework of tris(m-oxybenzyl)arene were synthesized, their bottom arene rings tuned their characteristic Lewis acidity, which was supported by theoretical calculation as well as catalytic application in a hetero Diels-Alder reaction.

We introduce a new approach to absolute continuity of laws of Poisson functionals. It is based on the energy image density property for Dirichlet forms and on what we call the lent particle method which consists in adding a particle and taking it back after some calculation.

HIV incubation period is the random time between the HIV-infection and the onset of clinical AIDS. Distribution of this non-negative random variable is known as HIV incubation period distribution. The Back-calculation method reconstructs the past pattern of HIV infection and predicts the future number of AIDS cases with the present infection status. It depends on three important factors: incuba...

Based on the equal-time Wigner function for the Klein-Gordon field, we discuss analytically the mechanism of pair creation in a classical electromagnetic field including back-reaction. It is shown that the equations of motion for the Wigner function can be reduced to a variable-frequency oscillator. The pair-creation rate results then from a calculation analogous to barrier penetration in nonre...

Recurrent neural networks (RNNs) trained with gradient-based algorithms such as real-time recurrent learning or back-propagation through time have a drawback of slow convergence rate. These algorithms also need the derivative calculation through the error back-propagation process. In this paper, a derivative-free Kalman filter, so called the unscented Kalman filter (UKF), for training a fully c...

This paper describes an efficient implementation of the Viterbi decoding algorithm on the ZSP500 digital signal processor (DSP) core. It starts with an introduction to convolutional coding and Viterbi decoding as a method of forward error correction in communication systems. An introduction to the ZSP500 architecture is followed by a description of special instructions for performing the Trelli...
