Chemical graph theory has recently gained much attraction among researchers due to its extensive use in mathematical chemistry. In this research article, We have studied the spectral properties such as eigenvalues, energy and Estrada index of some chemical structures such as Cupric oxide (CuO) and Graphene Oxide (GO). We have computed the energy E(G)=∑i=0n|λi| and the other invariant Estrada index EE(G)=∑i=1neλi of the above mentioned graph structures and obtain the polynomial regression analysis using machine learning techniques. This approach permitted us to predict the spectral values more precisely and analyze the difference between the actual and predicted values. The actual values of energy and Estrada index is represented by Eav and EEav while the predicted values of energy and Estrada index is represented by Epv and EEpv, where av represents "actual value" and pv represents "predicted value". We first use traditional method based on softwares and get the actual values (av) (see section 2). Then we perform machine learning techniques to generate a best fit model and get the predicted values (pv) of the energies and Estrada index of Cupric oxide CuO and Graphene Oxide GO by using the best fit second order polynomial for Energy and Estrada Index of CuO is obtained as E(CuO)=−0.007m2+5.892mn+2.243m+2.169n−0.365 and EE(CuO)=0.537+2.084m+2.084n+13.533mn, respectively. Similarly, the best fit second order polynomial for Energy and Estrada Index of GO is obtained as E(GO)=−0.266+2.533m+2.598n+0.014m2+3.133mn+−0.017n2 and EE(GO)=−1.671+4.400m+4.440n+0.016m2+6.553mn+0.014n2, respectively. We have observed the difference between av and pv which shows our machine learning model is best fit model as the error between the av and pv is minimum. © 2025 The Authors

作者： Amin, Mohamed Abdullkader, Hatem M. Ibrahem, Hani M. Sakr, Ahmed S. Mathematics and Computer Science department Faculty of Science Menofia University Egypt Information System department Faculty of Computers and Information Menofia University Egypt

In this paper, an efficient data hiding technique based on the discrete cosine transform (DCT) of image is proposed. In this technique, the DCT coefficient is quantized using a predefined mathematical operation then the secret bits are embedded in all frequency component of the quantized DCT coefficient using least significant-bit (LSB) to enable a large message capacity. A comparison between the proposed method and other existing methods is introduced. The results demonstrated that the performance of the proposed method is satisfied compared to them.

The Industrial Internet of Things (IIoT) seeks to improve smart factory productivity by leveraging automation and scalability. For automation in industry, optimization, collaboration and protection, and scalability, the IoTs paradigm, technology for communication and information, and intelligent systems are integrated as a single organism. This article presents a blockchain-assisted safe data-sharing mechanism that provides security requirements in the industry using IoT. End-to-end authentication is developed based on the blockchain’s reputation, and the smart contract is used to validate nodes’ security measures. Through integrity verification and categorization in node terminals and industry, the blockchain paradigm manages data collection and dissemination. An efficient proof of authentication (PoAh) consensus mechanism is created using the blockchain network to build a collaborative network to preserve logs and verification data in the industrial IoT. It accomplishes trustworthy authentication and endpoint activity tracing, and edge computing is used in blockchain nodes to offer device authentication processes that utilize smart contracts and PoAh. According to an experimental study, the proposed architecture lowers the authentication time and obtains a high response rate. The proposed system’s service time shows the efficiency of PoAh-based blockchain architecture for industrial IoT compared with existing works. Finally, we evaluated various block sizes to ensure an efficient transaction rate. The outcomes demonstrate the practicality of the suggested and put-into-practice architecture, distinguished by enhanced data audibility, device data ownership, security, and privacy while utilizing decentralized storage. © The Author(s) 2025.

Over the past decade, scheduling in distributed computing system has been an active research. However, it is still difficult to find an optimal scheduling algorithm to achieve load balancing for a specific scientific application which is executed in an unpredictable environment. This is due to the complex nature of the application which changes during runtime and due to the dynamic nature and unpredictability of the computational environment. This paper addresses these issues by presenting a Simulated Annealing (SA) approach as an optimizer which is an improved version of EG-EDF with Tabu Search optimizer. Instead of using Tabu Search, this work used SA to optimize the scheduling algorithm. The scheduling algorithms have been evaluated using three main criteria;number of delayed jobs, makespan time and total tardiness. Our results show the improvements to the main criteria mentioned.

Open source software adaptation in Africa: Is a matter of inferior or cheap is not quality?

引用

International Journal of Open Source Software and Processes 2014年第1期5卷 1-15页

The African continent has long benefited from adopting OSS in its private and public organizations that have changed their way of development, the use and how to acquire proprietary software. This frequency of adaptation does not appear to be in balance with the contribution to the OSS community. Using views from experienced software practitioners working in different organizations across two African countries it has been observed that neglected infrastructure, a wide availability of proprietary software and misconceptions of a clear meaning of Open Source Software across Africa have been an obstacle towards the participation in the OSS technology in the global network.

Generalization Bounds of ERM Algorithm with Markov Chain Samples

引用

Acta Mathematicae Applicatae Sinica 2014年第1期30卷 223-238页

One of the main goals of machine learning is to study the generalization performance of learning algorithms. The previous main results describing the generalization ability of learning algorithms are usually based on independent and identically distributed （i.i.d.） samples. However, independence is a very restrictive concept for both theory and real-world applications. In this paper we go far beyond this classical framework by establishing the bounds on the rate of relative uniform convergence for the Empirical Risk Minimization （ERM） algorithm with uniformly ergodic Markov chain samples. We not only obtain generalization bounds of ERM algorithm, but also show that the ERM algorithm with uniformly ergodic Markov chain samples is consistent. The established theory underlies application of ERM type of learning algorithms.

Network traffic measurement studies have shown the presence of self-similar behavior in both local area and wide area traffic traces. In this study we investigated the magnitude of the self-similarity behavior of network traffic and its Hurst measurement, H. Our study has revealed several characteristics of H based on the network traffic changes. From the finding, H can be used as traffic load indicated only if the sampling size is large. On the other hand for a smaller sampling size, H can be used to indicate the change in traffic pattern. However network traffic does not always exhibit self-similarity property. Activities such as peer-to-peer can steer the traffic to lose this property. © 2007 IEEE.

Blog quality model

International Journal of Web Based Communities 2013年第1期9卷 25-50页

Breakthroughs in technology are making the internet an ever-growing phenomenon, and we have witnessed an enormous growth of blogs in the blogosphere. However, the blogosphere has been crippled by disorganised and uncontrolled growth, and many blogs are of poor quality. Development domains, such as software engineering, website engineering, and information systems, have provided accepted models for the assessment of the quality of their products. However, to the best of our knowledge, there appears to be no standard model for the assessment of blog quality. In this paper, we propose a blog quality model as a guide for bloggers at large, with a set of 49 criteria grouped into 11 families of features that are relevant to blog quality. This model has been constructed by determining a set of criteria from a review of the relevant literature and blogs and then measuring the acceptability of these criteria by means of questionnaire surveys sent to sample populations of blog readers.

WSEAS Transactions on computers 2009年第1期8卷 48-59页

作者： El-Bakry, Hazem M. Mastorakis, Nikos Faculty of Computer Science and Information System Mansoura University Egypt Hellenic Naval Academy Greece

In previous work [27], the authors proposed an E-University but they did not take into account some essential parts. In this paper, the system presented in [27] is modified and developed. New critical important items such as security in E-Learning, learning management, business continuity management and science park are added to the proposed university. According to the great development of IT, the current Web-based learning systems need to be as effective as human tutors. Recently, intelligent agents became one of the most interesting subjects of modern information technology. Agent-based technology has been taken as an important approach for developing advanced E-Learning systems. This paper presents architecture for implementing a multi-agent system within the context of a learning environment. The roles of intelligent agents within an E-Learning system, called E-University, are presented. The agents perform specific tasks on the behalf of students, professors, administrators, and other members of the university. Also a group of intelligent agents for learning activities such as user interface agents, task agents, knowledge agents and mobile agents is developed. Using the multi-agent technology in E-Learning system, gives user interaction facility to both users and designers, and adds ability to exchange information between different objects in a flexible way.
