The Impact of Student’s Anxiety on u sing Learning Management Systems in Covid 19 Pandemic

The COVID-19 pandemic has compelled many educational institutions worldwide to use learning management systems (LMS) to deliver their courses. This study aims to determine the constituents that affect scholars when using LMS for graduation during the pandemic. This research also examines the impact of the students' anxiety level when using the LMS by conducting multiple group analyses with the partial least square's method. The results show a significant influence on the students' anxiety level when using the LMS. Students who have a low level of anxiety exhibited insignificant communication quality regarding the perceived ease of use and perceived usefulness. Meanwhile, students with a high level of anxiety highlight a consequential effect of communication quality in the perceived ease of use and usefulness. Moreover, students with a low level of anxiety displayed significantly high-perceived usefulness, satisfaction, and subject norm when using the LMS. In contrast, students with a high level of anxiety did not display perceived usefulness, satisfaction, or subject norm when using the LMS. As a result of the findings from this research, concrete effects can be provided for educationalists, policymakers, and practitioners, who want to advance functional procedures to enhance the design of the LMS during COVID-19.

Mathematical model of a communication channel with an unmanned aerial vehicle

In this paper, a mathematical model of a communication channel with an unmanned aerial vehicle and taking into account the specifics of the locations of a ground communication point when determining the effects of refraction, diffraction and interference of electromagnetic waves is proposed. A meaningful statement of the problem based on the mathematical relationship between the energy parameters of the first transmission equation and the quality indicators (BER) of the second transmission equation has been formed. The main features of calculating the parameters of the first equation are to determine the rules for calculating the level of attenuation due to the influence of the earths surface. The calculation of attenuations for cases of removal of an unmanned aerial vehicle from a ground communication point within the areas of line of sight, partial shade and shadow has been clarified. The second transmission equation is based on the mathematical model of the Rice communication channel. With respect to the energy parameters and the selected communication quality indicator for the formed mathematical model, examples of graphical dependencies are given in the study of typical computational problems. With respect to the energy parameters and the selected communication quality indicator for the formed mathematical model, examples of graphical dependencies in the study of typical computational problems are given.

"What is the Influence of Communication Quality Between the Business and IT Project Team on ERP Implementation Project Success?"

<p>Communication between the information systems (IS) specialist and the user has long been recognised in the IS literature as an important aspect of successful information system development projects. Since the 1970s IS researchers have studied the role of communication in the system development process and its influence on project/system success. Communication has been studied as a broad concept as well as in regard to specific aspects such as communication frequency, quantity, and the fit between the communication medium and the task. Yet, quality has been neglected. Therefore, this study presents the concept of "communication quality". The study investigated the influence of communication quality on project success in an Enterprise Resource Planning system implementation at a large North-American manufacturing company. ERP project implementation success was assessed by a multidimensional framework including multiple stakeholder perspectives. The study used supplementary secondary analysis of 54 interviews with project stakeholders from the IT project team and the business side of this organisation. The current study found support for the individual attributes of communication quality, namely completeness, credibility, accuracy, purpose adequacy, timeliness, openness, audience adequacy, bidirectionality, and a balance of formality vs. informality. The study found indications that a lack of communication quality might impact ERP implementation project success negatively whereas better communication quality might foster success. The ERP project at the organisation was successful in terms of traditional project success measures such as "on time" and "within budget". However, communication quality seemed to have a negative correlation to the quality of the relationship between the project team and the business as well as user satisfaction. System acceptance and use appeared to have been facilitated by better communication quality. The study enriches the IS literature by increasing the understanding of communication aspects during ERP implementation projects. It is also one of the first studies to introduce the new research method of secondary analysis of qualitative data from sociology into the IS field. Practitioners can apply the findings of this study to facilitate ERP implementation project success on a more holistic level addressing also user satisfaction and the quality of the relationship between the IT project team and the rest of the business.</p>

Smart substation network quality monitoring and fault prediction

The smart substation communication network is the basis for information sharing of various devices in the substation. Its operation status has an important impact on the safe operation of the substation and even the power grid. Therefore, real-time status monitoring of the smart substation communication network is becoming more and more important. Aiming at the problems of single dimension, insufficient real-time performance and manual fault analysis in existing substation communication network state monitoring technology, this paper proposes a method of smart substation communication network state monitoring and fault prediction based on network communication quality. This paper uses switch ACL technology and coloring technology to obtain communication quality indexes such as bandwidth utilization, delay, and packet loss rate in real time; based on a multi-dimensional evaluation algorithm, a comprehensive evaluation model of network communication quality is constructed; the model of the relationship between abnormal network communication quality and failures is established. Finally, real-time monitoring of network communication quality and fault prediction are realized. The application analysis in a typical 110 kV substation shows that this method can effectively evaluate the network communication quality and accurately predict failures, and can guide operationer and maintenaner to quickly restore the normal operation of the communication network.
