COVID-19: IoT Adoption in Healthcare
COVID-19 has disrupted normal life and has enforced a substantial change in the policies, priorities and activities of individuals, organisations and governments. These changes are proving to be a catalyst for technology and innovation. In this entry, we discuss the pandemic's potential impact on the adoption of the Internet of Things (IoT) in healthcare. Our perspective and forecast of this impact on IoT adoption is based on a thorough research literature review, a careful examination of reports from leading consulting firms and interactions with several industry experts. For each of these sectors, we also provide the details of notable IoT initiatives taken in wake of COVID-19. We also highlight the challenges that need to be addressed and important research directions that will facilitate accelerated IoT adoption.

Cow Behavioural Activities in Extensive Farms
Animal welfare is becoming an increasingly important requirement in the livestock sector to improve, and therefore raise, the quality and healthiness of food production. By monitoring the behaviour of the animals, such as feeding, rumination, walking, and lying, it is possible to understand their physical and psychological status. Precision Livestock Farming (PLF) tools offer a good solution to assist the farmer in managing the herd, overcoming the limits of human control, and to react early in the case of animal health issues. The entry highlights a key concern that occurs in the design and validation of IoT-based systems created for monitoring grazing cows in extensive agricultural systems, since they have many more, and more complicated, problems than indoor farms. In this context, the most common concerns are related to the battery life of the devices, the sampling frequency to be used for data collection, the need for adequate service connection coverage and transmission range, the computational site, and the performance of the algorithm embedded in IoT-systems in terms of computational cost.

Coyote Reconnaissance Vehicle
The Light Armoured Vehicle II (LAV II) Coyote (and the related Bison) are armoured cars (or armoured personnel carriers) built by General Dynamics Land Systems Canada for the Canadian Forces. They are a later generation of the LAV-25 and of the same family as the Australian ASLAV, as all are part of the Light Armoured Vehicle family produced by General Dynamics Land Systems - Canada and based on the MOWAG Piranha 8x8.

CPC with a Tubular Absorber
The compound parabolic concentrator (CPC) is a highly interesting solar collector technology for different low-concentration applications due to no tracking requirement. The CPC with a tubular absorber is the most common type of CPC.

CPTED in the Cyberspace Domain
The visual fidelity of a virtual environment lacks the exceedingly complex layers from the physical world, but the continuous improvements of image rendering technology and computation powers have led to greater demands for virtual simulations. Our study employs Crime Prevention through Environmental Design (CPTED) as a risk control measure and utilizes two principles: Access Control and Natural Surveillance. We conducted an experiment with (n-sample: 100) graduate students. For the experiment, we utilized the Factor Analysis of Information Risk (FAIR) to quantitatively analyze the risk. Furthermore, we adopted the lme4 package for R to estimate the mixed effect of the 6,242,880 observations retrieved from Kaggle. Based on the two experiments, we were able to critically evaluate the contributions of CPTED through a multi-component analysis. Our study investigates how spatial syntax and territorial demarcation may translate in the cyberspace realm. We found that the corollaries of the mophology in the virtual environment effects the distribution of crime. The results of our study discusses how to determine the criminogenic designs and capacity in the cyberspace realm.

Cr-free High-Temperature Water-Gas Shift Catalysts
Replacement of toxic Cr in the industrial Fe-oxide based High-Temperature Water-Gas Shift (HT-WGS) catalysts has been the focus of intense research in the past decades. In the current manuscript, we examine the promotion effect of Ca, Ni, Co and Ge as possible Cr substituents, and Ca and Ni are found to improve catalysts performance relative to Cr promotion. The current study, besides finding two promising Cr substitutes (Ca and Ni) for the HT-WGS reaction catalyst, also emphasizes on the qualities a promoter must possess to become a suitable substitution of Cr. The remarkable performance of Ca and Ni promoters are related to their ability to stabilize the surface area of the respective catalysts by making partial or complete solid solution with the bulk Fe-oxide phase and by promoting highly redox Cu0-FeOx interfacial sites on the catalyst surface. The poorer performance exhibited by Co and Ge promoters is related to the lack of their ability to promote the highly active Cu0-FeOx interfacial sites along with inability of Co to stabilize the surface area. All the promoters follow a redox type mechanism for the HT-WGS reaction.

Crack Analysis in Structures Using Image Processing Technique
Structural health monitoring (SHM) involves the control and analysis of mechanical systems to monitor the variation of geometric features of engineering structures. Damage processing is one of the issues that can be addressed by using several techniques derived from image processing. There are two types of SHM: contact-based and non-contact methods. Sensors, cameras, and accelerometers are examples of contact-based SHM, whereas photogrammetry, infrared thermography, and laser imaging are non-contact SHM techniques.

Crack Healing Technologies of Asphalt Pavement
Crack healing has been a key area of asphalt pavement research. Energy supply technologies (induction and microwave heating) have demonstrated significant efficacy in enhancing the crack healing capability of asphalt pavement, particularly in microcracks. Crack healing technologies can effectively prolong the service life of asphalt pavement, thereby further reducing the damage to the environment caused by road engineering, reducing energy consumption and CO2 emissions.

Cracking of Wireless Networks
Cracking a wireless network is defeating the security of a wireless local-area network (back-jack wireless LAN). A commonly used wireless LAN is a Wi-Fi network. Wireless LANs have inherent security weaknesses from which wired networks are exempt. Wireless cracking is an information network attack similar to a direct intrusion. Two frequent types of vulnerabilities in wireless LANs are those caused by poor configuration, and those caused by weak or flawed security protocols.

Craniofacial Bone Tissue Engineering
Craniofacial Bone Tissue Engineering aims to regenerate large bone defects in the craniofacial region that cannot heal spontaneously. Bone is a hard-vascularized tissue, which renews itself continuously to adapt to the mechanical and metabolic demands of the body. The craniofacial area is prone to trauma and pathologies that often result in large bone damage, thus leading to both aesthetic and functional complications for the patients. The “gold standard” for treating these large defects is autologous bone grafting, which has various drawbacks, such as the necessity for a harvesting site with sufficient bone volume, considerable morbidity and infection. Indeed, tissue engineering combining a biomaterial with the appropriate cells and molecules of interest would allow a new therapeutic approach to treat large bone defects while minimizing surgical complications.
