The main concept of metaverse is to connect augmented reality (AR) and virtual reality (VR) devices to achieve common share space for new applications and services. The existing internet of things (Iot) services shall support high interaction system architecture and techniques to respond to this application trend. Although the cloud computing based network services can support high and flexible computing and storage space, it still cannot satisfy the above real time interaction demand due to long transmission delay. The edge computing architecture is therefore proposed for task offloading requested by the clients to effectively utilize the computing resource provided by the edge server and save the energy of the client device. However, the communication and computing resource are limited and shall be properly arranged for tasks with diffe..... ReadMore -

Unsustainable patterns of production and consumption particularly in industrial countries are identified as the major causes of the continued deterioration of the global environment. The automotive industry is one of the main producers of industrial wastes affecting the natural environment. Automotive companies are in a difficult position to implement green supply chain management (GSCM). The number one barrier in the automotive sector is “market competition and uncertainty”. The second problem is “Lack of Implementing Green Practices”. Like these two barriers, cost implications, unawareness of customers, lack of corporate social responsibility, lack of globalization, lack of technical assistance from government have been identified as top-level barriers and lack of the government’s willingness to invest, reduced.....

With an ever increasing proportion of Internet traffic being encrypted, the role of transitive trust models (TTMs) is each day more important. From the main two TTM models, this text focuses on the decentralized Web of Trust, mostly used for e-mail exchange and document processing. Several high-profile vulnerabilities have been found in the Open PGP key server network, the main WoT implementation, leading it to an existential crisis. This article presents the main identified threat, and sketches several possible ways forward...... ReadMore

The COVID-19 pandemic has accelerated the digitization of education. Educators in different educational institutions began searching diverse online learning methods and tools in present materials, ensuring the quality of student learning. Open Educational Resources (OER) have been one of the significant trends of online learning platforms. During the pandemic, OER educators tried to reduce or eliminate tuition fees to raise students’ motivation of learning; however, it found that learners’ course completion rates turned lower than before as well as the instructor never updated the course and responded to student questions after the course was released. Recently, researchers have been searching for different ways to raise students learning motivation effectively, gamification is one of the popular methods. In this paper, the learning t..... ReadMore

Silicon with finite resistivity behaves differently at RF frequencies compared to generic substrate considered as a good dielectric such as alumina, RT-Duroid, FR4. Lossy as well as good dielectric material can be characterized by complex permittivity. Silicon which is considered as the lossy substrate also have considerable amount of dissipative energy associated with the complex permittivity. Permittivity is the property of the dielectric which indicates capacitance or stored charges mathematically associated with the imaginary part. The loss tangent can be deduced with the current density which in turn depends on complex permittivity. Material permittivity relates with the physical phenomena and main contributors are ionic conduction, dipole friction, and dipolar relaxation, atomic and electronic polarization [1]. Real part of the comp..... ReadMore

The usage of mobile devices has surpassed the usage of desktop computers. Even organizations are more committed to their projects and commercialization options based solely on mobile front-end performance. Mobile usage is growing rapidly. However, are there standard guidelines for building mobile sites? Is it possible to transform an already existing desktop site into a mobilefriendly site? This research answers these questions while transforming an existing user interface into a mobile- friendly site and offers detailed instructions for doing so. It presents standard guide- lines for future refactors, offers specific design guidelines for building such a design ground up and establishes how this can be a continuum for creating mobile-friendly designs......

Random graph models play an important role in describing networks with random structural features. The most classical model with the largest number of existing results is the Erd˝os-R´enyi random graph, in which the edges are chosen interdependently at random, with the same probability. In many real-life situations, however, the independence assumption is not realistic. We consider random graphs in which the edges are allowed to be dependent. In our model the edge dependence is quite general, we call it p-robust random graph. Our main result is that for any monotone graph property, the p-robust random graph has at least as high probability to have the property as an Erd˝os-R´enyi random graph with edge probability p. This is very useful, as it allows the adaptation of many results from Erd˝os-R´enyi random graphs to a non-independen..... ReadMore
