Current network design problems can be solved by offline or online methods. Offline methods are criticized for their complexity and in flexibility, whereas online methods lack guaranteed optimality. Non-blocking properties, which are typically studied in switching structures, could be used to evaluate the capability of a switching structure to…

The pandemic situation banned the presence of teachers and students in the classrooms disrupting the typical teaching process. Videoconferencing services have been used successfully for lectures, but they are insufficient for hands-on laboratories where the physical presence is a requirement (i.e. to access specific hardware). Enabling remote…

Troubleshooting is a particular problem-solving process comprising error detection, fault diagnosis, and system restoration. Since automation of systems has become increasingly complex and ubiquitous, troubleshooting skills are crucial to maintain safety and security in a variety of contexts. The planned study aims at examining troubleshooting…

The COVID-19 pandemic forced schools across the nation to increase their reliance on IT to deliver educational instruction to students. This amplified the vulnerability of K-12 schools to potentially serious cyberattacks. The US Government Accountability Office (GAO) was asked to review cybersecurity in K-12 schools. The objectives of this report…

This research study explores the challenges and barriers in school digital transformation based on the perspectives and experiences of school leaders within the Republic of Cyprus. This study employs a qualitative research approach, using interviews to collect insights from 11 purposively selected primary and secondary school leaders. The…

Introduction: This study investigates the implications of the interplay of multiple information infrastructures to learning and conducting work and to its related information work practices, and how the materialities of work and its infrastructures play into their intermingling. Method: The present study is based on an ethnography of a week-long…

Although there have been numerous technological advancements in the last several years, there continues to be a real threat as it pertains to social engineering, especially phishing, spear-phishing, and Business Email Compromise (BEC). While the technologies to protect corporate employees and network borders have gotten better, there are still…

Over four semesters of a large introductory statistics course the authors found students were engaging in contract cheating on Chegg.com during multiple choice examinations. In this paper we describe our methodology for identifying, addressing and eventually eliminating cheating. We successfully identified 23 out of 25 students using a combination…

Contribution: A technical course in a multidisciplinary university program has to provide high-level skills, with limited lecturing hours and student background. This article investigates the principles for its design and reports about a study case. Background: The overall course organization needs to address specific learning targets and teaching…

Mobile apps have the potential to support collaborative fieldwork even where web connectivity is unreliable or unavailable. To explore this potential, we developed portable network infrastructure and custom-made field tool apps. We deployed this solution in remote communities in the far north of Australia, in connection with co-located cooperative…

The research is focused on a comprehensive analysis of digitalization as a prerequisite for higher education modernization. The authors of this article consider the digital divide as a component of information inequality, which has a technological nature and presupposes unequal opportunities for access, use, and production of information and…

Purpose: Inclusive growth in the education sector is still a major challenge in some countries because of limited access to technologies and internet connectivity, among other reasons. However, as a technology, augmented reality (AR) is expected to be widely used in the field of education in the future. The main purpose of this paper is to explore…

Since early development of information technologies, in particular computers and the Internet, there has been tension between those who believe these new technologies and their applications they have been mired in tension. Originally conceived and developed as tools for enabling high level, nonhierarchal engagement in problem-solving and…

The Internet of Things (IoT) is a network of objects that can exchange data with other devices also connected to the Internet. One of the most common consumer examples of IoT is home automation, as a variety of smart devices, including doorbells, lightbulbs, thermostats, and refrigerators are now available which users can control remotely using…

Motivated by applications in health care systems, this study focused on queueing network models with instances of simultaneous resource possession under capacity restrictions in different stages. Customers during service at certain nodes in the first-level or primary system may simultaneously need service from a second-level server. In this…
