Modelling The South African Covid-19 Induced Web Traffic Data Shift Using Artificial Neural Networks, Judah Soobramoney, Retius Chifurira, Temesgen Zewotir

Applied Mathematics & Information Sciences

In response to the coronavirus pandemic of the year 2019 (Covid-19), several governments around the world restricted commercial, economic and socio-economic activities. For emerging markets like South Africa, the pandemic and subsequent restrictions have negatively impacted the financial standing of many sectors, corporates and households. Several corporates that rely on digital technologies such as website marketing experienced a steep decline in traffic flow onto the website and a distinct change in online behaviour. Whilst such change in online behaviour directly impacted the revenue of corporates, such data shifts posed further challenges to the accuracy of machine learning models that were …

Exploring The Factors Influencing Employee Awareness Of Social Engineering Threats: A Review, Mohammed Fahad Alghenaim, Nur Azaliah Abu Bakar, Fiza Abdul Rahim Jul 2022

Exploring The Factors Influencing Employee Awareness Of Social Engineering Threats: A Review, Mohammed Fahad Alghenaim, Nur Azaliah Abu Bakar, Fiza Abdul Rahim

Applied Mathematics & Information Sciences

Phishing is a dynamic threat, making it much more dangerous because a lack of awareness among employees makes it much more difficult for the business to detect and respond to Phishing situations. Social engineering is a process that essentially involves human interactions that can be exploited to the point where typical security methods become defective. The most dangerous risk of social engineering is that the criminals understand human nature and may exploit vulnerabilities without the victims realizing it. This study examines relevant research to determine the factors that may influence employee awareness of social engineering threats. Three demographic factors and …

Optimal Packing Of Two Disks On Torus, Zh. Kh. Zhunussova, Ye. K. Ashimov, K. A. Dosmagulova, L. Kh. Zhunussova

Applied Mathematics & Information Sciences

The article is devoted to recently established connection between the packing problem of disks on torus and the effective conductivity of composites with circular inclusions. The packing problem is usually investigated by geometrical arguments, the conductivity problem by means of elliptic functions. An algorithm is developed in order to determine the optimal location of two disks on torus formed by the hexagonal lattice and square lattice. The corresponding minimization function is constructed in terms of expressions consisting of elliptic functions with unknown arguments. The numerically found roots coincide with the previously established optimal points by a pure geometrical study.

Applied Mathematics & Information Sciences

The goal of this manuscript is to present a new contractive mapping, namely a C ́iric ́-type rational (α∗,η∗,Λ,Υ)-multi- valued contraction mapping. In the framework of ordinary metric spaces, several fixed point results for semi α∗-admissible multi- valued contraction mappings with respect to η are also given. In addition, we have an example to back up our research. Finally, several fixed point results with a graph were discussed to improve the effectiveness of our contraction. In the same way, our findings expand, generalize and unify a large number of solid articles in the same direction.

Bayesian Inference Based On Pooled Sample From Two Independent Samples Of Record Values, A. R. Shafay

Maximum likelihood and Bayesian methods are used to estimate the unknown parameters. Bayesian estimation is discussed using three different loss functions. The problem of predicting record values from a future sample is also discussed. In addition, the results of the exponential and Pareto distributions are shown as examples.

A graph is said to be cordial if it has a 0−1 labeling that satisfies certain properties. The third power of path P3, is the graph n obtained from the path Pn by adding edges that join all vertices and with d ≤ 3. In this paper, we show that Pn3 is cordial if and only if n ̸= 4. Moreover, we study the cordiality for the sum of pairs of the third power of paths. Keywords:

On Categorical Property Of Fuzzy Soft Topological Spaces, S. Saleh, Radwan Abu-Gdairi, Tareq M. Al-Shami, Mohammed S. Abdo

Applied Mathematics & Information Sciences

The main aim of this work is to provide a categorical framework for fuzzy soft topological spaces FST. We define some of their subcategories such as Top, STop, δτ-FST, χ􏰀-FST, and α􏰀-FST. In general, we initiate some functors between them and discuss some results and relations of fuzzy soft maps. The relationships between FST and their subcategories are studied, for instance, we show that Top, STop are bireflective full subcategories of FST and α􏰀-FSTis a bicoreflective full subcategory of FST. Moreover, we demonstrate that Top, δτ -FST, and χ􏰀-FST are isomorphic.

From Generalized Arithmetic Means To Bregman Divergences And Back, Henryk Gzyl Jul 2022

From Generalized Arithmetic Means To Bregman Divergences And Back, Henryk Gzyl

Applied Mathematics & Information Sciences

Here we examine some connections between the notions of generalized arithmetic means, geodesics, Lagrange-Hamilton dynamics and Bregman divergences. The key ingredient for the relationship is the case in which a Riemannian metric has a square root that is the Jacobian of a diffeomorphism. In such case the geodesics of the of the Riemannian metric turn out be the pullback of straight lines by the diffeomorphism. This is interesting when the Riemann metric is the Hessian of a convex function because in this case we obtain comparison results between the Bregman divergence determined by the convex function and the geodesic distance …

The Eccentric Zagreb Indices For The Subdivision Of Some Graphs And Their Applications, Hanan Ahmed, Ammar Alsinai, Aysha Khan, Hakeem A. Othman

Applied Mathematics & Information Sciences

Subdivision is one of the most important aspects of graph theory as it enables us to calculate the properties of some complicated graphs using some of the easier graphs. To understand the different properties of chemicals, laboratory tests must be performed, and this is extremely expensive. To overcome this problem, many topological indices in theoretical chemistry have been introduced and defined. In this paper, we calculate the eccentric Zagreb indices for the subdivision graphs of some graphs. Also, these indices were examined in their predictability of the boiling point of the chemical compounds.
