An IoT Real-Time Potable Water Quality Monitoring and Prediction Model Based on Cloud Computing Architecture.

In order to achieve the Sustainable Development Goals (SDG), it is imperative to ensure the safety of drinking water. The characteristics of each drinkable water, encompassing taste, aroma, and appearance, are unique. Inadequate water infrastructure and treatment can affect these features and may also threaten public health. This study utilizes the Internet of Things (IoT) in developing a monitoring system, particularly for water quality, to reduce the risk of contracting diseases. Water quality components data, such as water temperature, alkalinity or acidity, and contaminants, were obtained through a series of linked sensors. An Arduino microcontroller board acquired all the data and the Narrow Band-IoT (NB-IoT) transmitted them to the web server. Due to limited human resources to observe the water quality physically, the monitoring was complemented by real-time notifications alerts via a telephone text messaging application. The water quality data were monitored using Grafana in web mode, and the binary classifiers of machine learning techniques were applied to predict whether the water was drinkable or not based on the data collected, which were stored in a database. The non-decision tree, as well as the decision tree, were evaluated based on the improvements of the artificial intelligence framework. With a ratio of 60% for data training: at 20% for data validation, and 10% for data testing, the performance of the decision tree (DT) model was more prominent in comparison with the Gradient Boosting (GB), Random Forest (RF), Neural Network (NN), and Support Vector Machine (SVM) modeling approaches. Through the monitoring and prediction of results, the authorities can sample the water sources every two weeks.

Reduction of energy consumption using remote Variable Frequency Drive (VFD)

The use of technology in irrigation is a parameter to be considered when there is a need for energy savings and greater process control. In several situations, it is necessary to adjust the characteristics of the hydraulic system during operation of the motor shaft in the irrigation system. The use of a Variable Frequency Driver (VFD) changes the frequency of the motor pump to allow the rotation of the motor shaft to suit the needs of the hydraulic system. With a change in the amount of water in the catchment tank, it becomes necessary to adjust the rotation of the motor shaft to a new head. The objective of this study was to develop a system capable of allowing remote control of a Variable Frequency Drive that controls a motor pump that feeds the central pivot. The system was developed from a microcomputer board Raspberry model and an Arduino microcontroller board controlling a potentiometer of 200k and it was observed that three motor-pump-inverter assemblies presented differences in the significance level between the data of the system and the obtained data. The data showed a strong positive correlation. This system can be an alternative when it is not possible to change the inverter parameters in the field.

Driver Safety System

Abstract: Blind spots in vehicles and driver drowsiness are significant safety concerns that contribute to road accidents. To address these issues, we propose a comprehensive driver drowsiness and blind spot detection system using advanced technologies and image processing algorithms. The blind spot detection system employs ultrasonic sensors and an Arduino microcontroller board to gather real-time information about potential collision objects in the blind spot area. When a risk is detected, an LED alarm alerts the driver, enhancing their awareness and reducing the likelihood of accidents. Additionally, we explore the implementation of a camera-based blind spot detection system using deep learning techniques, offering a viable option for autonomous vehicles. For driver drowsiness detection, we present a non-intrusive method using a camera to continuously monitor the driver's facial features, such as eye and head movements. By analyzing these features, the system can accurately identify three driver states: awake, drowsy, and sleeping. When drowsiness is detected, the system activates alerts, such as visual and auditory cues, to awaken the driver and ensure their safety. The literature review greatly impacted our system's design, facilitating informed decisions and integration of cutting-edge technologies for an effective driver drowsiness and blind spot detection solution. The research paper also discusses the integration of these systems into various platforms, including mobile apps, Python programs, and IP cameras, providing flexible and cost-effective solutions for different vehicle types. Results from prototype implementations demonstrate the effectiveness and reliability of the proposed methods in detecting blind spots and drowsiness. Overall, this research enhances road safety via efficient blind spot & drowsiness detection, saving lives by addressing driver fatigue. Utilizing tech & machine learning, proposed systems advance active safety & driver assistance

This article presents the design and development of a flexible tooling system for sheet metal bending. The flexible tooling system aims to reduce manufacturing disturbances and increase the efficiency of the forming process. First and foremost, the structural behaviour of the sheet metal is investigated using the finite element method for the numerical simulation of the three-point bending process. The analysis’ findings enabled the prediction of component reaction to loads, which are essential for the further optimization and enhancement of the tooling system’s flexibility. At the initial stage of the development phase, SolidWorks, the computer-aided design software, is utilized to visualise the flexible tooling system and improve the tooling connectivity design. Furthermore, the prototype is developed by integrating mechanical and electrical components, such as the Arduino Mega microcontroller, stepper motors, and digital stepper drivers. Automation is achieved by programming the Arduino microcontroller board and controlling the stepper motors’ movement to ensure precise displacement and speed control of the forming tools. The tooling system’s major qualities are its high flexibility, achieved through the implementation of two moveable support cylinders and the possibility of being further upgraded to a closed-loop forming system. The higher level of automation and optimization of the sheet metal bending process can lead to improved processing efficiency and help achieve the desired formed products with higher quality and the required geometric tolerance. It is expected that the development of a flexible tooling system will find widespread application in sheet metal bending processes, resulting in reduced material costs, rapid equipment set-up and higher processing repeatability.
