Smart grids have developed as a potentially game-changing strategy for controlling the demand and supply of energy. Unfortunately, peak demand is a significant source of grid instability and rising energy prices, making it one of the most critical difficulties in smart grids. During times of high energy demand on the grid, demand response (DR) strategies incentivize consumers to change how they use energy. This study’s overarching goal is to learn how DR methods may be used to help smart grids make better use of their energy resources. The primary research is to develop a smart DR system that can predict times of high energy demand and proactively alter usage to reduce such periods. Machine learning strategies are utilized in the proposed system to estimate peak demand via past data, weather predictions, and other variables. The system will then alter energy use based on real-time data from smart meters along with other sensing devices to meet the projected demand. The simulation model will include several scenarios for testing the DR system’s flexibility, including a range of weather conditions, load profiles, and grid topologies. Several indicators, including peak demand reduction (80.04%), energy savings (38.09%), environmental consequences, and reaction time ( © 2024 Taylor and Francis Inc.. All rights reserved.

The securing of clean and sustainable water sources is a fundamental entitlement of individuals and an essential factor in the sustained advancement of societies. Alternative water resources, springs can serve as a primary water source for small, remote communities. The preservation of the security and quality of spring water is of the highest priority. This study provides an assessment of the security of spring water resources within the community, facilitated through the utilization of an Internet of Things (IoT) monitoring system. The study aimed to assess the variations in temperature, turbidity, pH, TDS, and electrical conductivity of spring water on the NDUM campus over the course of a day, specifically during the morning, afternoon, and evening periods. The monitoring was conducted over a span of one year to capture potential patterns and changes. The obtained data is sent to the cloud by using an IoT-based ThingSpeak application to monitor the quality of water. As a result of the collected data, the system provides an efficient water quality parameter monitoring system, and early warning can be taken to reduce any harmful effects to the environment. The outcome of this study may contribute to the proposal of a new way of monitoring water quality on campus by using a real-time system. In addition, the outcome also provides baseline information about water quality for the welfare of society and supports the green campus campaign, which may also help in future water security and sustainability planning for the NDUM campus area. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

Tracing and tracking of the peripheral devices help in terms of manufacturing and providing services to the users. However, most of the current systems which are suggested by Food and Drug Administration (FDA) are loT and Hardware-Assisted Tracing data which are being stored as required. The time and effort on duplicating record keeping and third-party validations are wasting of time and effort towards verification process. Record-keeping systems can be attacked by fraud and cyber-attacks whereas Blockchain is ideal for delivering that information securely and in a distributed fashion. This research has proposed a Blockchain based traceability of the computer Peripherals in Universities scenarios. It is well-known that the Blockchain is a shared, immutable ledger that facilitates the process of recording transactions and tracking assets in a business network. Smart contract is a good feature for maintaining this kind of peripheral data. In addition to providing quality information, the proposed traceability system enables transparency, safety, and security. We have done security analysis also. © 2023 IEEE.

The main food that people in India consume on a daily basis is paddy. According to data, the stress caused by rice illnesses, which reduce yields by 70%, was felt by the paddy farmers. If not controlled within a certain time frame, these plant diseases, which are typically brought on by pests, insects, and pathogens, have a significant negative impact on productivity. This research proposed auto encoders rooting convolutional neural network model to control these paddy diseases, and it has been implemented with various per-trained models like Vgg16, Resnet50, and inceptionV6. This model accurately determines whether a paddy plant is healthy or has one of four different types of paddy diseases. These models were developed, tested using auto encoders and a dataset of thermal pictures that was made available to the public, and they achieved the maximum model accuracy of 90.6%. A 84.8% was attained in the prior iteration without the use of auto encoders. With the use of this model, people can quickly detect paddy illness and assist farmers in raising productivity and yield. © 2023 IEEE.

Serverless computing has emerged as a promising research subject in computer science as it grows in favor among developers because of its low cost and elasticity. However, one primary concern that has cropped up in recent months with serverless computing is vendor lock-in: It can be hard to port to another vendor's platform without considerable effort and cost. Serverless on AWS is a new way to build cloud-native IoT systems that are highly performant, highly resilient, and low maintenance. We'll implement exciting design concepts for serverless systems on AWS in this paper using the open-source OpenWhisk software. To provide low-cost and maintenance-free IoT services, traditional cloud service providers offer platforms that are progressively migrating toward the serverless approach. OpenWhisk takes care of the infrastructure, servers, and scaling with Docker and containers. Because Apache Open Whisk’s components are built using containers, it provides a wide range of deployment options in cloud environments. Many of today’s prominent Container frameworks such as Kubernetes are available as options. The Kubernetes framework is a well-known open-source container-orchestration system widely used in industrial and academic fields. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
