This article describes a practical method for improving quality in lead-acid battery production by combining metrological support with quality management. Key manufacturing steps, such as grid casting and paste application, often vary and can cause faults like cracked plates and shorter battery life. The study introduces a framework that standardizes how important measurements ...

Conventional sequential PCB testers are inefficient, as a single failure halts all subsequent tests, leading to incomplete diagnostic data and delayed fault isolation. This study proposes a parallel virtual instrumentation framework in LabVIEW to overcome these limitations. By leveraging asynchronous execution, the framework runs multiple independent tests concurrently, continuing ...

The article reviews the core technological components that enable intelligent and energy-efficient control of modern tobacco curing systems. Traditional flue-curing is a highly energy-intensive process relying heavily on subjective manual control, leading to high fuel consumption and variable leaf quality. This review focuses on the integration of Machine Vision (MV), specifically ...

This research presents an automated soil analysis system integrating NPK sensors with machine learning for precision agriculture. The framework employs Arduino UNO microcontroller and ESP8266 Wi-Fi module to capture real-time nitrogen, phosphorus, and potassium levels from soil samples. Collected data transmits to cloud infrastructure where trained algorithms process nutrient ...

Encrypted messaging apps have become a center for illegal activities, especially drug trafficking, because of their privacy features. Telegram, in particular, offers anonymous group chats, channels, and bots that share information about drug supplies around the world. This paper presents a system that uses AI to detect drugrelated content on Telegram. We collect data from publicly ...

Underground mining operations pose critical safety hazards which can be fatal. The ICT-enabled mine safety system discussed in this paper enables real-time monitoring of underground mining operations. RFID technology was utilized for real-time zonal localisation of miners and mobile equipment. GPS technology was incorporated for precise localisation. Echolocation technology was ...

Optical encoders are widely used in precision positioning, yet signal amplitude attenuation due to grating tilt degrades phase resolution and linearity. In this manuscript, we analysed the amplitude-related resolution and proposed an auto-gain method based on programmed gain control and the CORDIC algorithm to stabilize sinusoidal signals. Experimental results demonstrate that ...

Mobility impairments caused by spinal cord injuries, stroke, and degenerative disorders limit independence for millions worldwide. This study presents a low-cost lower-limb exoskeleton that decodes user intention in real time using electroencephalographic (EEG) and electromyographic (EMG) signals. The system employs a PIC16F877A microcontroller executing adaptive impedance control ...

Mobile operators have long relied on hardware-centric core infrastructures that are costly, rigid, and slow to scale. As 5G service demands increase, these systems create bottlenecks, necessitate expensive upgrades, and result in unused data. This study simulates a cloud-native 5G Standalone (SA) core on AWS integrated with AI/ML analytics. Cloud deployment ensures elasticity, ...

The purpose of this project is to design and construct a 12 V DC to 220 V AC inverter using components such as the TL494 PWM IC, MOSFET and a center tap transformer. The TL494 will serve as the oscillator responsible for generating a 50 Hz alternating electromagnetic field. The TL494 will be configured to produce a wave output at the desired frequency of 50Hz. This wave will be ...
