Some sufficient conditions on certain constants which are involved in some first and second-order differential subordinations associated with functions positive real part like modified Sigmoid function, exponential function Janowski obtained so that the analytic [Formula: see text] normalized by condition text], is subordinate to function. The admissibility for used as a tool proof of results. ...

A Back Propagation Artificial Neural Network (BPANN) is a well-known learning algorithmpredicated on a gradient descent method that minimizes the square error involving the networkoutput and the goal of output values. In this study, 261 GPS/Leveling and 8869 gravity intensityvalues of Iran were selected, then the geoid with three methods “ellipsoidal stokes integral”,“BPANN”, and “collocation” ...

We investigate the computational power of recurrent neural networks that apply the sigmoid activation function _(x)=[2 (1+e)]&1. These networks are extensively used in automatic learning of non-linear dynamical behavior. We show that in the noiseless model, there exists a universal architecture that can be used to compute any recursive (Turing) function. This is the first result of its kind for...

Machine learning algorithms perform differently in settings with varying levels of training set mislabeling noise. Therefore, the choice of a good algorithm for a particular learning problem is crucial. In this paper, we introduce the “Sigmoid Rule” Framework focusing on the description of classifier behavior in noisy settings. The framework uses an existing model of the expected performance of...

Abstract The study focuses on the validation of leaf unfolding (LU) onset oak stands in Western Carpathians 2000–2021 derived from MODIS satellite data. LU was annual trajectories Normalised difference vegetation index (NDVI) fitted with a double sigmoid logistic function. metric Growing speed day (GSD) corresponding to is represented by first derivative Ground-based observations 22 phenologica...

wandering spleen is an uncommon entity in adults and has been described only rarely with sigmoid volvulus, that rarely affects children and adolescents. it is usually described in adults.wandering spleen characterized by the abnormal location of the spleen, caused by incomplete fusion of the four primary splenic ligaments, allowing the spleen to be mobile within the abdomen.the wandering spleen...

The process related to the changes in dimensions and mass of grape berry passes through two growth phases separated by a lag phase, can be described double sigmoid curve. onset their duration are important factors for understanding processes berries. A new method quantitative determination was developed present study. In this method, phase transition dates correspond times at which rate change ...

The growing number of security threats has prompted the use a variety techniques. most common tools for identifying and tracking intruders across diverse network domains are intrusion detection systems. Machine Learning classifiers have begun to be used in threats, thus increasing systems’ performance. In this paper, investigation model an systems based on Principal Component Analysis feature s...
