This study presents a comparative performance evaluation of WiMAX (IEEE 802.16e) and 3G (UMTS/HSPA) networks for rural connectivity scenarios, using simulation-based experiments conducted in NS-2 and OPNET Modeler environments available up to 2014. Key performance indicators—throughput,…

This manuscript presents the design, implementation, and evaluation of a gesture-controlled robotic arm employing triaxial accelerometer sensors for intuitive human–machine interaction. The primary objective is to develop a real-time system that translates human hand gestures into…

This manuscript presents the design and implementation of a standalone embedded system for real‐time temperature monitoring, utilizing commonly available microcontrollers and analog temperature sensors as of 2014. The proposed system emphasizes low cost, low power consumption,…

Real-time obstacle avoidance remains a critical capability for autonomous mobile robots operating in unstructured environments. Ultrasonic sensors, owing to their low cost, simplicity, and robustness, have been widely adopted for proximity detection. This manuscript presents a…

This manuscript investigates vibration control in rotating machinery through the implementation of tuned mass dampers (TMDs). Rotating equipment commonly experiences resonant vibration due to unbalanced forces, aerodynamic loads, and structural interactions. Such vibrations can lead to…

This manuscript presents a comprehensive failure analysis of welded joints in heavy-duty structures, focusing exclusively on technologies and practices available up to 2014. Welded joints are critical stress-bearing elements in bridges, offshore platforms, pressure vessels, and…

Enhancement of heat transfer in plate heat exchangers (PHEs) has been an active area of research within thermal engineering disciplines. The introduction of nanofluids—suspensions of nanoparticles within conventional base fluids—has demonstrated potential to increase the rate…
