    The Internet of Things' fundamental goal is to enable the automated flow of data between two systems or devices without the need for human intervention. Certain communication protocols enable this automated information sharing between two devices. The goal of this research is to determine how effective IoT technologies are in research. The descriptive-analytical research approach was used, as well as the utilization of library resources. The use of undefined networks (SDN) and increasing IoT quality indicators using SE2 and SP2 techniques, utilizing a security framework based on evolutionaryalgorithms to increase IoT security, and leveraging blockchain in IoT, as well as LPWAN technologies, were all investigated in this study. SP2 enhances the performance of controller plates, which can minimize service latency in spectral computing, according to the findings. By changing the number transfers in each VM independently, SE2 may give different functionality between control panels. The encryption and decryption processes employ genetic algorithm (interaction and mutation) operations, and GA (interaction and mutation) procedures are applied to each pair of blocks to aid the IoT function

    Risk management framework in Agile software development methodology

    Get PDF
    In software projects that use the Agile methodology, the focus is on development in small iterations to allow both frequent changes and client involvement. This methodology affects the risks that may happen in Agile software projects. Hence, these projects need a clear risk management process to reduce risks and address the problems before they arise. Most software production methodologies must use a framework for risk management, but currently, there is no such framework for the Agile methodology. Therefore, we present a risk management framework for projects that use the Agile methodology to help the software development process and increase the likelihood of the project’s success. The proposed framework states the necessary measures for risk management according to the ISO31000 standard at each stage of the Agile methodology. We evaluated the proposed framework in two running software projects with an Agile methodology by a number of expert experts. The results show that using our proposed framework increases the average positive risk reaction score by 49%

    Prediction of target displacement in structural systems plays a significant role in performance-based design and rehabilitation of structures. In this study, the γ factor for different hardening ratios, including 1, 2, 3, 5, 7.5, 10, and 15 percentages, stiffness-strength-deterioration models, and soil type classes is determined to modify the energy balance equation in performance-based plastic design (PBPD). Statistical results indicate that the effect of the hardening ratio, deterioration, and soil type class on the capacity curve is considerable. Therefore, a simple equation based on the period of the vibration and ductility is suggested to estimate the γ factor in different structural systems. Moreover, four 1-, 3-, 7-, and 12-story moment steel structures with various hardening ratios in the material are designed to validate the proposed method. The suggested values for the γ factor show exact results compared to collected displacements from time history analysis, while the error in the previous work was considerable. Statistical results showed that the mean error in the previous method in estimating target displacement for 1-, 3-. 7-, and 12-story structures is about 15%, 20%, 20%, and 32%, respectively. Conversely, the mean error in this study for estimating target displacement of 1-, 3-. 7-, and 12-story structures is about 10%, 7%, 6%, and 15%, respectively. Finally, the proposed method is examined on the empirical reinforced concrete (RC) bridge pier simulated numerically with fiber-based modeling. Similarly, the suggested equation estimates the target displacement appropriately for the concrete model compared to achieved displacements from nonlinear dynamic analysis
