Underwater marine and freshwater environments are vast and mysterious, but our ability to explore them is limited by the inflexibility and inconvenience of monitoring systems. To overcome this problem, in this work, we present a proof-of-concept deployment of a real-time Internet of Underwater Things (IoUT) using blue light-emitting-diode-based visible light communication (VLC). Pulse-amplitude modulation with four levels is employed. To relax the focus point and increase the received power, four avalanche photodiodes (APDs) are adopted. Moreover, to reduce the error rate, the convolutional code with constraint-7 is used, which is the simplest to implement. Encoding and decoding are implemented by a field-programmable gate array. The results are verified by experimental demonstration. A baud rate of 9600 is used, but, unfortunately, we only have a 2 m long tank. System performance is improved when the number of APDs is increased; we investigated the effects of up to four APDs. Notably, bit error-free data transmission can be achieved. Additionally, this method would make underwater monitoring very conventional and dependable, and low-cost real-time monitoring would be possible, with data shown on the Grafana dashboard tool.

The development of microgeneration plays an important part in the strategy of the decarbonization of the world economy. However, its diffusion faces different barriers, including the information and technical barriers on the side of the end-user. This paper contributes to the literature by providing a comparative cross-country analysis of the role of the corporate sector in providing the installation and technical servicing of PV solar panels and small wind turbines in the Republic of Armenia, India, Russia, and the United Arab Emirates. Business proposals from the microgeneration equipment market were analyzed by studying the official websites of companies offering autonomous and backup power supply solutions, followed by interviews with company representatives using the “mystery shopper” method. The study reveals that, of the four surveyed countries, the Republic of Armenia has the highest level of representation of service companies on the Internet (4.71 companies per million population). It is followed by the United Arab Emirates (1.9 companies per million population) and the Russian Federation (0.29 companies per million population). India ranks last in this indicator (0.02 companies per million population). The Republic of Armenia has the highest level of corporate sector development, with such essential features as cooperation with commercial banks for providing potential consumers with financial support and involvement in educational activities for the population. The main feature of the Indian corporate sector is orientation on the B2B format in building customer relationships. In Russia and the United Arab Emirates, the effect of implementing large projects with state support is still limited and does not extend to the general population. Full article

The concept of blockchain was introduced as the Bitcoin cryptocurrency in a 2008 whitepaper by the mysterious Satoshi Nakamoto. Blockchain has applications in many domains, such as healthcare, the Internet of Things (IoT), and data management. Data management is defined as obtaining, processing, safeguarding, and storing information about an organization to aid with making better business decisions for the firm. The collected information is often shared across organizations without the consent of the individuals who provided the information. As a result, the information must be protected from unauthorized access or exploitation. Therefore, organizations must ensure that their systems are transparent to build user confidence. This paper introduces the architectural design and development of a blockchain-based system for private data management, discusses the proof-of-concept prototype using Hyperledger Fabric, and presents evaluation results of the proposed system using Hyperledger Caliper. The proposed solution can be used in any application domain where managing the privacy of user data is important, such as in health care systems. Full article

Interdisciplinary cross-cultural and cross-organizational research offers great opportunities for innovative breakthroughs in the field of smart cities, yet it also presents organizational and knowledge development hurdles. Smart cities must be large towns able to sustain the needs of their citizens while promoting environmental sustainability. Smart cities foment the widespread use of novel information and communication technologies (ICTs); however, experimenting with these technologies in such a large geographical area is unfeasible. Consequently, smart campuses (SCs), which are universities where technological devices and applications create new experiences or services and facilitate operational efficiency, allow experimentation on a smaller scale, the concept of SCs as a testbed for a smart city is gaining momentum in the research community. Nevertheless, while universities acknowledge the academic role of a smart and sustainable approach to higher education, campus life and other student activities remain a mystery, which have never been universally solved. This paper proposes a SC concept to investigate the integration of building information modeling tools with Internet of Things- (IoT)-based wireless sensor networks in the fields of environmental monitoring and emotion detection to provide insights into the level of comfort. Additionally, it explores the ability of universities to contribute to local sustainability projects by sharing knowledge and experience across a multi-disciplinary team. Preliminary results highlight the significance of monitoring workspaces because productivity has been proven to be directly influenced by environment parameters. The comfort-monitoring infrastructure could also be reused to monitor physical parameters from educational premises to increase energy efficiency. Full article

Internet anomalies produce data and images beyond any authorship or source. They seem to compute and display the depths and potentials of the net “as such.” Explanations and theories surround and attempt to account for anomalies, from ARGs to NSA recruiting tools. Examining three such anomalous YouTube channels, this essay does not propose a solution but rather maintains the anomalous as the constituent aesthetic and community of the net. Full article
