Impact of Covid-19 on cyber Security

The Covid-19 pandemic is an unforeseen occurrence that took the world by storm. Governments and businesses were unprepared, hence the large-scale impact it continuously has on the planet. It has permanently revolutionised how we live, work and interact with technology. With this new way of living, businesses and governments had to adapt to a new form of survival, and so did cybercriminals; there was a surge in cyber threats due to our newfound dependence on technology. This paper emphasises the common types of cyber threats and the targeted industries. These attacks were more successful because people were uneasy and desperate, which gave the criminals more incentive to attack businesses. To avoid being a cyber target, I have provided recommendations against future threats.

Dating Apps: The Uncertainty of Marketised Love

Dating apps promise a ‘digital fix’ to the ‘messy’ matter of love by means of datafication and algorithmic matching, realising a platformisation of romance commonly understood through notions of a market’s rationality and efficiency. Reflecting on the findings of a small-scale qualitative research on the use of dating apps among young adults in London, we problematise this view and argue that the specific form of marketisation articulated by dating apps is entrepreneurial in kind, whereby individuals act as brands facing the structural uncertainty of interacting with ‘quasi-strangers’. In so doing, we argue, dating app users enact a Luhmanian notion of interpersonal trust, built on the assessment of the risk of interacting with unfamiliar others that is typical of digitally mediated contexts dominated by reputational logics. From a sociocultural perspective, dating apps emerge as sociotechnical apparatuses that remediate the demand to rationally choose a partner while at the same time reproducing the (im)possibility of doing so. In this respect, far from offering a new form of efficiency, they (re)produce the ontological uncertainty (Illouz, 2019) that characterises lovers as entrepreneurs.

An approach with multi-tier automotive knowledge formalization for troubleshooting activities

Automotive troubleshooting process integrates repairing activities that are executed through auto professionals when they note phenomenon or conditions and determine about inspections, instructions, or checks, so as to tackle the trouble that affects a car. This study is focused on the knowledge representation for the aim of decision making in automotive troubleshooting process for automotive braking system. To reach this purpose, there are three phases followed: (1) a knowledge representation with procedural mode is investigated from an aspect of decision making; (2) a simple, instinctive, and efficient architecture of automotive knowledge formalization is presented; (3) an approach to generate troubleshooting procedures is defined. A new form, named diagram of expanded transformation (DoET), to represent knowledge and depict three fundamental tiers of decision making in the present or future disposal: processing strategy, quantity, and inapplicability. The approach can be also utilized manually to create DoETs from auto repair manuals (ARMs) or to build them spontaneously applying the messages feasible on workshop lists regarding single, multi-tier troubleshooting processes. The DoETs with auto repair manuals for auto braking system is validated. The acquired model can be utilized as a base structure for troubleshooting assisted systems generation.

The Physical and Mechanical Properties of Autoclaved Aerated Concrete (AAC) with Recycled AAC as a Partial Replacement for Sand

The application of AAC has increased considerably in Malaysia since the 1990s. The usage of AAC has some advantages, but it also has negative environmental impacts since rejected concrete will become landfill. This study aimed to use AAC waste powder as a material that would partially replace the sand content to produce a new form of Autoclaved Aerated Concrete (AAC). The physical and mechanical properties of the newly developed AAC were investigated. This paper presents improved mechanical and physical properties of the new form of recycled AAC concrete. Besides these improvements, using recycled AAC could lower production costs. Furthermore, the usage of this recycled waste powder is both economically and environmentally advantageous. This study found that when recycled AAC was substituted for sand, AAC with a fine recycled powder content of 30% had a compressive strength that was around 16% higher than conventional AAC and between 29% and 156% higher than any value attained utilizing an industrial waste product. This study also confirmed that the greater strength could be identical to a higher tobermorite phase and that the recycled AAC surface showed a finer crystalline morphology.

Reclaiming the People: Counter-Populist Algorithmic Activism on Israeli Facebook

This article examines a new form of resistance to right-wing populist discourse on social media which I define as counter-populist algorithmic activism. Practitioners of this type of activism exploit platforms’ automated ranking mechanisms and interface design to bolster the online visibility of counter-populist voices. By so doing, activists seek to stymie the digitally mediated spread of right-wing populist rhetoric and advance an alternative, non-exclusionary vision of “the people.” To explore this nascent form of resistance, this study draws on a year-long online ethnography of a Facebook group of Israeli activists called Strengthening the Left Online. Through an observation of the group’s activities during 2017, as well as interviews with its main administrator and other left-wing Facebook users, I elucidate the distinctive nature of the motivations, strategies, and goals that guide counter-populist algorithmic activists.

5G in Healthcare

5G is a new universal wireless standard, a new form of mobile network engineered to bring everyone and everything virtually together. 5G is not only for mobile phones, but it is also the foundation for virtual reality (VR), the internet of things (IoT), and autonomous driving, connecting many electronic devices to the internet. Having good healthcare is very important as it affects all parts of human life and social well-being. Moreover, it is crucial to have a great healthcare system if we want economic growth, workforce productivity, and society to advance. Despite all the hard work done by scientists and medical professionals, today's healthcare is mainly inefficient, and a significant overhaul is required. This chapter discusses the primary advantages, including the 5G's main features in healthcare and their limitations and probable solutions and applications to the latest scenario.
