Abstract

Manual treadmills are low-cost and widely accessible but lack electronic systems for measuring running speed, limiting their use in interactive or gamified applications. This study presents a simple embedded system that enables real-time speed tracking on a manual treadmill using a magnetic reed switch and an ESP32 microcontroller. Each roller rotation generates one pulse which is processed through an interrupt-based algorithm to compute linear speed. The data are transmitted to a custom Unity game application to control a running avatar in real time. Experimental results show an average speed error of 2.11% with an RMSE of 0.049 m/s and an end-to-end latency of 48 ± 4.9 ms. The findings indicate that the system is accurate, responsive, and suitable for low-cost exergaming and motion-based training.

Abstract

One way to diagnosing a disease is by examining an image. To display an image on a specific component, an inverse matrix-based algorithmic decomposition technique is used. If the Lambert-Beer Law equation is subjected to a natural logarithmic operation, a linear relationship between intensity level and thickness will be produced. Furthermore, an image can be displayed based on the thickness function. By varying three different wavelengths and three different materials, three types of linear equations are obtained. This variation in wavelength affects the level of decomposition. The results show that the combination of 780 nm-808 nm-980 nm wavelengths is better in quality than other wavelength variations. In this study, a phantom composed of silicone rubber, margarine, and gelatin was used. This phantom material is representative of the human body material.

Abstract

Photoplethysmography (PPG) adalah teknik non-invasif untuk memantau denyut jantung dan saturasi oksigen, namun rentan terhadap noise. Penelitian ini bertujuan mengoptimalkan kualitas sinyal PPG melalui desain dan implementasi sistem filter analog dan digital. Sistem terdiri dari sensor pulse dan Arduino Uno untuk akuisisi data, diikuti oleh rangkaian filter analog dan filter digital. Variasi nilai resistor gain dan kapasitor pada low pass filter rangkaian analog dianalisis untuk mendapatkan kinerja hasil terbaik. Hasil pengujian menunjukkan bahwa kombinasi filter analog dan digital berhasil meningkatkan Signal-to-Noise Ratio (SNR) dari 4.61 dB menjadi 19.57 dB. Denyut jantung dari sinyal yang telah dioptimasi mencapai 61.60 BPM yang di validasi dengan peak detection yang mampu mendeteksi peak dengan benar. selain itu, Baseline Wander Index (BWI) sebesar 0.18. Hasil penelitian membuktikan bahwa sistem optimasi menghasilkan sinyal PPG yang bersih dan akurat untuk aplikasi monitoring kesehatan

Abstract

The increasing penetration of renewable energy, especially wind energy based on Dubly Fed Induction Generator (DFIG), poses challenges in maintaining power system stability. One mitigation approach is the use of a Parallel Resonance Fault Current Limiter (PRFCL), which can limit fault currents and dampen oscillations during major disturbances. This study uses MATLAB/Simulink to simulate a DFIG-integrated IEEE 9 Bus system and evaluate the impact of PRFCL on transient stability during three-phase-to-ground faults. The results show that PRFCL significantly reduces voltage and power deviations, accelerates frequency recovery, and improves the Fault Ride-Through (FRT) capability of DFIG systems.
