This article aims to calculate the net income achieved by a prosumer for an existing On-Grid system of photovoltaic panels consisting of a set of 12 poly crystalline panels with a nominal power of 250 Wand 60 cells and an On-Grid inverter (StecaGrid model) with a maximum power of 3000 W. The prosumer is located in southern Romania, Ilfov County. Modeling of the photovoltaic panel in Matlab / SIMULINK was performed using a mathematical model, and it was compared with a real data set. Next, an analysis was made of the energy produced by the photovoltaic system, and the energy consumed by the prosumer, the excess energy being introduced in the national energy system. We have achieved a net income saving for March, so the analyzed photovoltaic system has energy efficiency that can significantly reduce electricity costs over time. Thus, using the Matlab / Simulink model, photovoltaic systems can be designed to satisfy the needs of prosumers.

Agent-based computing is an active field of research with the goal of building autonomous software of hardware entities. This task is often facilitated by the use of dedicated, specialized frameworks. For almost thirty years, many such agent platforms have been developed. Meanwhile, some of them have been abandoned, others continue their development and new platforms are released. This paper presents a up-to-date review of the existing agent platforms and also a historical perspective of this domain. It aims to serve as a reference point for people interested in developing agent systems. This work details the main characteristics of the included agent platforms, together with links to specific projects where they have been used. It distinguishes between the active platforms and those no longer under development or with unclear status. It also classifies the agent platforms as general purpose ones, free or commercial, and specialized ones, which can be used for particular types of *** Codes 68T42 Copyright © 2020, The Authors.

In the context of SaaS (Software as a Service) where software has to be up and running 7 days a week and 24 hours a day, keeping the requirements specification and related test cases up to date can be difficult. Managing requirements in this context has additional challenges that need to be taken into account, for instance, re-prioritize requirements continuously and identify/update new dependencies among them. When requirements change, related test cases need to be updated accordingly. We claim that extracting and analyzing the usage of the SaaS can help to maintain requirements and test cases updated and contribute to improve the overall quality of the services provided. This paper presents an extension to REQAnalytics. REQAnalytics is a recommendation system that collects information about the usage of a SaaS and generates recommendations to improve the SaaS provided. The evolution involves extending the analysis performed over the sequences of functionalities (requirements) and refining the data provided for Software Requirements Specification, with the purpose of helping the requirements engineers in the requirement maintenance activities, and to improve the overall quality of the services. Furthermore, the extension presented in this paper is able to generate test cases in a regression testing context.

The state of network paths is of great importance for the quality and reliability of the transmission of information coming from the IoT devices. Changing network conditions cause the state of a single path to be highly unpredictable, especially when large-scale IoT networks, connecting thousands of specialized devices, are in use. The solution to this problem is to perform trials in a real environment, with the use of real hardware. The rationalization of the design, the implementation and the exploitation of the process will be the main benefit of this approach. In this demonstration, a testbed infrastructure for the estimation of the state of path parameters in wired and wireless networks is presented. The estimation is based mainly on active measurements performed with the use of the Probing Packet Trains method. The key elements of the testbed infrastructure are locally and remotely controlled energy-efficient single-board computers, working under the control of the Linux operating system, which are equipped with software able to track (in manual or automatic mode) changing conditions of a given transmission path.

The process of detecting and identifying errors early in the life-cycle of any software has many challenges. The tools used for model checking are however becoming more effective and usable because they are helping the identification of errors. This has empowered users to apply model checking to large-scale problems. The process of validating the model implementation is normally harder. We created a Promela model by using a model checker called Spin in order to verify the Medical Social Media System based on Social Oriented Networks by using M-Health technology and sensors in smartphones and bracelets for medical data acquisition, in order for it to be used in the healthcare sector in Iraq. For the Promela Model, we first described the behaviors of the Medical Social Media Systems via UML timelines. After that, we combined the UML timelines in state diagrams that were finally transformed into a Promela model and verified with the Spin model checker. © 2019 IEEE.

The article concerns modern soft magnetic materials made by rapid solidification and subsequent ultra-rapid annealing. Due to the lower amount of non-magnetic elements, higher magnetisation is possible. Unfortunately, the lack of those elements causes difficulty during isothermal nanocrystallisation operation, being crucial from the final product properties point of *** of isothermal heat treatment, ultra-rapid annealing is implemented. It reflects in materials with good magnetic softness and higher possible magnetisation *** amorphous alloy with Fe75.3Ni10B14Cu0.7 chemical composition was heat treated between cooper blocks at 773K in the range of 1-60s. To study structure evolution, we brought XRD, DSC, Flash DSC, Mössbauer spectroscopy, TEM, and HRTEM techniques to *** on the DSC results, we estimated the minimum heating speed to obtain optimal structure at 6000K/min. The Mössbauer results allowed us to study annealing time-dependent local atomic ordering in the amorphous state. A comparison of X-Ray and synchrotron diffraction results drove us to the conclusion that X-Ray measurements are sufficient to determine the material structure. TEM shows the formation of α-Fe crystallites even after an annealing time of 0.5s. The increase in annealing time leads to an increase in the crystalline phase volume fraction and growth of α-Fe crystallite size. © 2023, The Authors. All rights reserved.

In the wake of the Covid-19 pandemic, Ambient Assisted Living (AAL) and Home Monitoring System (HMS) frameworks came into focus as an alternative to classic healthcare services for the ageing world population. Both overwhelmed healthcare systems and the susceptibility of older adults to develop severe complications are indicators that in the near future there will be a shift to a decentralized monitoring paradigm for chronic disease *** paper introduces the SMARTCARE system, a solution that integrates both AAL and HMS features in order to provide maximum flexibility in defining monitoring scenarios through the use of IoT devices. More, the system tackles the lack of uniformity that exists in standardization across the IoT field through the use of a modular architecture.

Online teaching is a reality and a necessity especially since the appearance of the COVID-19 outbreak. In order to facilitate the proper conduct of this process, several steps are required: to have in place a secure infrastructure to store data and to handle the data flow, to manage the student and teacher information, and to facilitate the teacher-student communication so students have access to courses and teachers can properly evaluate the students. This paper presents a distributed architecture for identity management of university students and teachers, while considering aspects pertaining to user privacy and security. Also, a solution is proposed for easy integration with third-party solutions that facilitate online teaching and learning, i.e., Microsoft Office 365, Google G Suite and the Moodle educational platform, and access to the university's Wi-Fi network with the same credentials. The implementation of the solution at the "Gheorghe Asachi" Technical University of Iasi, Romania allowed classes to be carried out online and students to be evaluated also online.
