Distortion describes how the natural metric on the graph differs from the induced metric from an embedding into a Euclidean space or other metric spaces. In this paper, we mainly explain two parts. In the first part, we focus on the problem of proving ...

Topological indices are significant, and they have a great part in chemistry. The molecular graph models molecular compounds. The structural formula of a chemical compound relative to the graph can be represented by a molecular graph. The vertices of ...

A theory of active agents is presented which aims to simulate dynamical complex networks. As complex systems involve many-to-many interactions, the ability to predict the evolution of the system is greatly affected by the ability to take into account ...

This paper aims to firstly, holistically analyze Cholesky decomposition, an efficient technique of decomposing a Hermitian, positive-definite matrix into the product of its lower triangular matrix and the conjugate transpose, and secondly, explore the ...

Principal loading analysis is a dimension reduction method that discards variables which have only a small distorting effect on the covariance matrix. We complement principal loading analysis and propose to rather use a mix of both, the correlation and ...

Based on MATLAB and matrix displacement method, the finite element program of plane bar system structure is designed in this paper, and its compiling idea and application method are explained with examples. The program is written according to the ...

Carbon price and coal price are key variables in management and risk decisions in activities related to the burning of fossil fuels. Different major players in the carbon market, such as companies, government and investors, have different time horizons. ...

In this paper, it will be shown cooperation between Petri nets and neural networks. The approach to the formation of the structure of a neural network with the help of Petri nets model , which you can describe the algorithms and, in particular, ...

Breaks in water consumption records can represent apparent losses which are generally associated with the volumes of water that are consumed but not billed. The detection of these losses at the appropriate time can have a significant economic impact on ...

This study aims to prove the existence of classification of compact, connected surfaces (without boundaries) up to homeomorphisms. In the first part of the paper, we prepare the basic knowledge that we should know before we start to consider the top ...

The rapid growth of social media has been witnessed during recent years as a result of the prevalence of the internet. This trend brings an increasing interest in simulating social media which can provide valuable insights to both academic researchers ...

We show that on an enhancement of the capacity of the function space used in regression, LASSO simultaneously decreases bias and variance of statistical models obtained in machine learning from training data, if the balance between minimization of the ...

Pandemic COVID-19 has been a big storm for the world. The spread of COVID-19 has suspended almost all sectors in human life including education. Because of this, various universities around the world have transferred traditional face to face teaching to ...

In pharmaceutical and medical studies, randomized controlled trials (RCTs) aim to prove that a new treatment has better or superior efficacy than standard treatment or placebo. In fact, RCTs can also be used to evaluate the efficacy of a new treatment ...
