Abstract The realm of refrigeration industry has marked its significance for storing food and beverages. Refrigeration warehouses are extensively used to store various combinations of large fresh food stock at favourable temperatures to maintain its quality. Any deviations from these favourable temperatures pose negative impacts on the cold stock. Hence, it is essential to minimize the margin of these potential risks that can incur huge loss to the cold-storage industries. On-site evaluation can be reliable to address these risks, but it is time consuming and an inefficient process as human intervention can be prone to manual errors. The paper, therefore, proposes a methodology to build a smart IoT system to remotely monitor and evaluate the refrigeration warehouses seamlessly at one’s fingertips using a mobile or laptop through dashboards. Furthermore, this paper addresses the difficulties in managing and analysing the large sensory data which are the result of seamless monitoring by unleashing the power of edge computing and cloud computing.

Abstract The COVID-19 pandemic has laid bare the need for contactless operations. While unmanned aerial vehicles (UAVs) are being developed to aid humans in countless domains, the need for effective battery management and performance optimization remains a huge task. The proposed solution, the “AeroDock”, aims to tackle these challenges by using wireless power transfer (WPT) technology coupled with smart monitoring of the drone’s health. The performance and hardware checks are assessed at the user end via cloud computing and IoT technology. This system is contact-less, safe, reliable and its usage is not affected by external factors. Thus, the AeroDock is a smart docking station for UAVs which eliminates the need for human intervention in effective charging and maintenance.

Abstract Disposable packaging tools such as cups/food containers have become popular and commonly used items in today’s society as they offer simplicity, low cost, durability, and convenience for people in carrying/taking their foods. Most of these packaging tools are non-biodegradable products because their materials are mainly composed of plastics and/or their derivatives. Consequently, packaging tools have become one of the primary contributors to the earth’s waste and global warming. Eco-friendly products can be defined as products that are safe and healthy for individuals and communities throughout their life cycle, which includes all processes from production to consumption and up to disposal. Current methods for developing eco-friendly products have mainly relied on using composites of different biodegradable materials that are chosen and combined in such a way that they can complement each other’s weakness or drawback. One of these composites with the potential to replace and address the negative impacts caused by plastics products is the bamboo fiber-PLA (BF-PLA) composite. This paper is intended to briefly discuss the characteristics of as well as various important properties of such a BF-PLA composite to illustrate and motivate its potential future use as an alternative eco-friendly material for producing disposable packaging tools.

Today, artificial intelligence (AI) can use the most powerful edge computing systems in the Internet of Things (IoT) for finding the information extracted from vast sensory data such as cyber effects or models in physical environments for classification, identification, and prediction. Heterogeneous IoT devices produce isolated and dispersed information parts, and knowledge sharing and exchange in IoT intelligent applications with several selfish nodes are necessary for complex tasks. In both academia and business, IoT is driving a digital revolution. However, protection and IoT privacy problems are challenged. It offers comfort for everyday lives. Blockchain, a shared cryptographic database, is a promising IoT encryption solution for several manufacturing, finance, and trade sectors. The IoT-based blockchain architecture is an interesting contrast to the conventional, centralized paradigm that struggles to fulfill specific IoT requirements. New concepts for applying data and resources management protection procedures in distributed networks and cloud computing are introduced. Cloud management services can be linked to the application through blockchain technology and distributed leader, a stable cognitive information system that facilitates management operations and securing data. This document provides many ideas for applying personal and behavioral characteristics to security and cryptography protocols, blockchain based on the cognitive cloud computing (BC-CCC) pattern. The simulation result shows that the proposed strategy can significantly enhance data transmission rate (96.2%), security ratio (94.5%), throughput ratio (92.4%), scalability ratio (91.5%), trust rate (93.8%), data trading ratio (96.2%), and reduce storage cost rate (25.1%) compared to other existing methods.

Benefits And Costs

AbstractResidential household owners were surveyed in two different New Hampshire communities that varied in terms of population size, degree of rurality, and per capita income, each with no activities in land application of biosolids. Logit models were developed and logistic regression analyses were carried out for each community. The empirical results suggest that the perception by residents of the potential economic benefits and negative impacts from land application of biosolids can be very influential in achieving public acceptance. From a policymaker's viewpoint, this suggests the need for sound educational programs that explicitly describe the economic benefits, negative impacts, and potential risks that typically occur with land application of biosolids. Supportive studies are needed to complement the educational programs. These measures will allow residents to weigh the relative benefits and costs to determine their positions on this approach to management of biosolids and to discount emotional judgements and misinformation. The media needs to ensure that newspaper, magazine, and television reports are accurate and taken from reliable sources. Survey results suggest that the less volume of information presented by the media, the more supportive residents are of land application. Therefore, with such sensitivity by respondents to quantity of information, it is imperative that media outlets place high priority on the quality and accuracy of materials presented. Socioeconomic characteristics of the respondents did not influence attitudes toward acceptance or rejection of biosolids application, thus eliminating the difficulty that social stratification could cause in achieving acceptance.
