Scientific Exploration into the Promising Realm of Magnetic Energy: A Literature Review
Full text linkABSTRACT: The use of permanent magnets, renowned for their self-sustaining magnetic properties, has been predominantly confined to small-scale generators. Conversely, electromagnets, composed of iron or steel cores cocooned within a web of wires, exhibit magnetization when subjected to an electrical current, consequently engendering a magnetic field. This intriguing aspect of magnets has kindled the scientific community's interest, particularly in the realm of electricity generation, where they have proven remarkably effective. As the world stands on the precipice of depleting finite oil reserves, the fundamental question looms large: What will serve as humanity's anchor when the last drop of oil is extracted from the Earth's depths? Could the advent of magnetic energy usher in a new era, redefining our reliance on conventional energy sources? These critical queries serve as the guiding compass for our scientific exploration into the promising realm of magnetic energy
Smart Water Quality Monitoring and Treatment Using IoT Technology
Full text linkThe primary purpose of this study is to design and build a water quality monitoring and treatment system with the concept of the Internet of Things (IoT) using Arduino Mega as a core controller, an esp8266 wifi module to connect to the internet, and smartphones to control and monitor the system. The system utilized a water level sensor to monitor the water level in the tank to avoid possible overflow, and to monitor the essential parameters of water quality such as PH, turbidity, total dissolved solids, and chlorine content, and to perform chlorination as a treatment process to maintain chlorine residuals in water. The Blynk App framework was used to integrate the system into the Internet of Things. In addition, a liquid crystal display (LCD) is employed to view the parameters of water quality, if the internet is not available.
These sensors wirelessly send the data they continuously collect on water quality indicators to a centralized server for processing. The server responds to requests for smartphones that the Blynk Apps has installed. The automated control mechanisms are put into place at the water treatment control stage based on the data analysis. Additionally, the smart water monitoring and treatment system has user interfaces that can be accessed via web and mobile applications. These interfaces give stakeholders remote access to real-time information about the quality of the water as well as personalized alarms. Such accessibility improves the ability to make decisions and enables quick responses to crucial water quality occurrences. From the results and findings of the research, the IoT-based Water Quality Monitoring and Treatment System is efficient and effective in detecting water quality and provides treatment using automatic chlorinatio

Some of the services are related to Government offices such as Ministry of Labor and Royal Oman Police [3]. The Sanad Service Centers are licensed offices [3] and few of their services are intermediary in nature between the applicants and Government bodies. The Sanad Offices are operating physically and processing the request of different types of applications for individuals and companies such as visa processing, visa renewal and many others. To avail the offered services, physical handling of documents and visits are needed which can be transformed based on the idea of this paper is presenting. The advancements in this sector will have a major impact in a bigger scope to facilitate the large number of end-users with convenience and simplicity.
The paper highlights the transformation and implementation of Online Sanad Services and will discuss the advancements of digital transformation to mobilize the services accessible to end-user in better, fast, timely, remotely, and secure manners. The transformation of Sanad Services from brick-and-mortar to click-and-mortar scenario will be an advantage and beneficial for all the stakeholders. It will reduce the chances of documents misplacement and ensure the availability of the contents for reuse as some of the services are required to complete and repeat on periodical basis due course of time.
The study aims to design an industry specific model that can serve in the implementation and development of Online Sanad Services to meet the challenges of modern world requirements. The basic elements discussed and represented in this paper are the solution architecture comprises the system architecture, process modeling, data flow modeling, entity relationship modeling, and system requirements of the proposed system
Atom Connectivity and Connectivity Energy of few Molecules
Full text linkFor a given chemical compound, a molecular graph could be constructed. The total of the absolute measures of Eigen values taken from adjacency matrix of the molecular graph for the assumed chemical compound is known as the energy of graph. It has been observed that, the adjacency matrix derived from the molecular graph has no information about the atoms and bonds connected. To overcome this limitation, we have considered the atom-connectivity and connectivity matrix which give more information about the classification of bonds and atom- connectivity of a chemical compound in the molecular graph. In this paper, we enhance our results on the atom connectivity energy graph and also few hydrocarbons are compared with the ordinary energy
Smart Waste Segregator with Overflow Control Mechanism
Full text linkWaste disposal is a major issue today, with well-known negative impacts on the environment, human health, and animal life. This research proposes a low-cost automated trash segregator with an overflow management system for efficient small-scale garbage disposal. The system uses sensors to segregate waste into different categories and also detects bin capacity to prevent overflow. It is designed to be cost-effective and user-friendly, making it suitable for household and small-scale waste disposal. The system employs three sensors to segregate metallic, dry, and wet wastes that serve as the input devices connected to the Arduino microcontroller. Furthermore, three ultrasonic sensors monitor bin capacity independently. Its affordability and user-friendly design make the system well-suited for household and small-scale waste disposal. Future improvements may include integrating machine learning algorithms and internet connectivity for better monitoring and management

Growth rate has been illustrated with three standard examples. Growth rate depends up on vorticity function, velocity profile and wave number. Furthermore, we obtained upper and lower bound for neutral phase speed. Also, we derived an instability regions depending on Rayleigh-Synge-Michael discriminant, velocity profile and radii
IoT-based Smart Traffic Cone System to Avoid Traffic Congestion and Improve Road Safety
Full text linkChain-reaction automobile accidents are a common occurrence, especially on freeways. Several reasons can lead to these collisions, such as speed, failing to see stop signs for oncoming traffic, and unforeseen road conditions. The Internet of Things (IoT)-Based Smart Traffic Cone System is created as a solution to these problems. It makes use of a variety of sensors and IoT technologies that are elegantly incorporated into the traffic cone's design. It is a solar-powered smart portable device in the shape of a traffic cone. Particularly on two-way roads, the traffic cones are positioned strategically in the median of the road. In addition, a traffic display panel is placed near the signal to make necessary adjustments before encountering traffic jams. A Bluetooth system is used to alert the drivers inside their vehicles about the road conditions. This initiative is aimed at the VISION 2040 of Oman, which emphasizes the creation of smart and sustainable cities with advanced IT infrastructure. The smart traffic cone represents an innovative solution developed after long research and with the recommendations and guidance of the Royal Oman Police (RoP) for the advancement of smart city development. Through continued research and development efforts, the functional prototype of the Traffic cone system has been successfully developed
