The Impact

This paper investigates the effects of digital production and information technologies on the development of logistic systems of different kinds: megalogistic, macrologistic, and micrologistic. The notions of a logistic system and types of logistic systems imply that logistics is considered in its broad sense as a modern methodology for managing all types of flows that appear in the process of socioeconomic activities of society and business: material, information, energy, financial and labor flows. The methodology discussed in this paper gives the answer to the question of what impact digital production and information technologies have on the development of various types of logistic systems. The methodology includes building a mathematical model in which the endogenous variables of the model reflect the resulting variables of the logistic system, while the exogenous variables reflect digital production and information technologies. The mathematical model is a system of interdependent dynamic econometric equations. Each equation is an autoregressive distributed lags model. In the model, the current values of an endogenous variable depend on their previous values, as well as on the current and previous values of other endogenous and exogenous variables. The novelty of the research is in the developed methodology for a comprehensive assessment of the impact made by digitalization on a totality of the interrelated and interdependent resulting indicators of the logistic system. A comprehensive assessment of the impact made by digitalization on a totality of interrelated and interdependent indicators of the logistic system is understood as a change in the indicators of the logistic system due to the effect of digitalization. The proposed methodology for a comprehensive assessment was empirically tested for Salesforce company.

Makalah ini membahas tentang model matematika dampak perubahan iklim terhadap kondisi makroekonomi suatu negara. Dengan mengacu pada model pertumbuhan ekonomi endogen pada suatu negara, dengan fungsi output berbentuk fungsi Cobb-Douglas akan diturunkan model matematika yang mendeskripsikan dampak perubahan iklim terhadap kondisi makroekonomi suatu negara. Selanjutnya, akan dikonstruksikan pula fungsi ongkos yang berhubungan dengan model matematika yang telah diturunkan. Mengingat model matematika tersebut masih dalam bentuk sistem persamaan nonlinear, maka diperlukan proses linearisasi untuk menghasilkan model matematika yang linear sehingga memudahkan untuk dianalisis maupun diaplikasikan. [This paper discusses the mathematical model of the impact of climate change on the macroeconomic conditions of a country. By referring to an endogenous economic growth model in a country, with the output function in the form of a Cobb-Douglas function, a mathematical model will be described that describes the effects of climate change on the macroeconomic conditions of a country. Furthermore, it will also construct cost functions related to mathematical models that have been derived. Considering that the mathematical model is still in the form of a nonlinear equation system, a linearisation process is needed to produce a linear mathematical model that makes it easy to analyze and apply.]

One of the key processes in software development and information security management is the evaluation of vulnerability risks. Analysis and evaluation of vulnerabilities are considered a resource-intensive process that requires high qualifications and a lot of technical information. The main opportunities and drawbacks of existing systems for evaluation of vulnerability risks in software, which include the lack of consideration of the impact of trends and the degree of popularity of vulnerability on the final evaluation, were analyzed. During the study, the following information was analyzed in the structured form: the vector of the general system of vulnerability evaluation, the threat type, the attack vector, the existence of the original code with patches, exploitation programs, and trends. The obtained result made it possible to determine the main independent characteristics, the existence of a correlation between the parameters, the order, and schemes of the relationships between the basic magnitudes that affect the final value of evaluation of vulnerability impact on a system. A dataset with formalized characteristics, as well as expert evaluation for further construction of a mathematical model, was generated. Analysis of various approaches and methods for machine learning for construction of a target model of dynamic risk evaluation was carried out: neuro-fuzzy logic, regression analysis algorithms, neuro-network modeling. A mathematical model of dynamic evaluation of vulnerability risk in software, based on the dynamics of spreading information about a vulnerability in open sources and a multidimensional model with an accuracy of 88.9 %, was developed. Using the obtained model makes it possible to reduce the analysis time from several hours to several minutes and to make a more effective decision regarding the establishment of the order of patch prioritization, to unify the actions of experts, to reduce the cost of managing information security risks

Secretion Clearance

Mechanical insufflation-exsufflation (MI-E) secretion clearance system is usually utilized to help patients to clear secretion. In this paper, to obtain the essential dynamic characteristics of volume-controlled (VC) MI-E secretion clearance system with double lungs, a dimensionless model of the MI-E secretion clearance system is derived. Furthermore, for the validation of the mathematical model, a prototype VC MI-E secretion clearance system is proposed. Finally, to reveal the impact of key parameters on VC MI-E secretion clearance system, a dimensionless orthogonal experiment with four factors and five levels was processed. And then, coupling effects of two lungs on VC MI-E secretion clearance system were illustrated. This paper can be referred to in treatment of secretion clearance with VC secretion clearance system.

The Impact

The article describes the role of polarisation in calculation of multiple reflections. A mathematical model of multiple reflections based on the Stokes vector for beam description and Mueller matrices for description of surface properties is presented. On the basis of this model, the global illumination equation is generalised for the polarisation case and is resolved into volume integration. This allows us to obtain an expression for the Monte Carlo method local estimates and to use them for evaluation of light distribution in the scene with consideration of polarisation. The obtained mathematical model was implemented in the software environment using the example of a scene with its surfaces having both diffuse and regular components of reflection. The results presented in the article show that the calculation difference may reach 30 % when polarisation is taken into consideration as compared to standard modelling.
