Abstract

An increasing of public attention to the quality of food has been increasing, recently. One type of food that consumed is quail eggs (QE). In this study, QE were tested by Electrochemical Impedance Spectroscopy (EIS) method with some parameters such as complex impedance, dielectric constant, and loss tangent analysis. Several interesting results showed that dielectric properties of QE experience a fluctuation phenomenon if the test is influenced by storage duration, qualitatively. Therefore, we approximately prove that QE quality can be tested via EIS to obtain fine results.

Abstract

Cyanidin-3-glucoside (C3G) is a flavonoid compound that is an antioxidant and natural colorant widely found in berries and vegetables such as red cabbage. This study aims to explore the structural stability of C3G using computer simulations based on force field theory through Avogadro software. In this study, the Universal Force Field (UFF), Merck Molecular Force Field (MMFF94), and General Amber Force Field (GAFF) methods were used to analyze the stability of C3G. The energy optimization results showed that the Ghemical method produced a more stable structure than other methods, although there was a discrepancy with GAFF. The GAFF method was more stable than UFF, but required more energy to achieve stability. Overall, the difference in force field methods affected the molecule's stability through optimization energy and structure parameterization variations, which affected the distance and angle of atomic bonds. These findings provide an efficient picture of the stable conformation of C3G, which can be applied in the food, health, and cosmetic industries.

Abstract

A stable and accurate navigation system is crucial for the operation of Autonomous Underwater Vehicles (AUVs), especially in underwater environments where GPS signals are unavailable. This study aims to enhance AUV navigation performance by optimizing the use of a low-cost inertial sensor, the MPU6050, through calibration and signal processing techniques. The methodology includes reading raw data from accelerometer and gyroscope sensors, performing static calibration to reduce bias and noise, applying Fast Fourier Transform (FFT) for signal analysis, and implementing digital filters such as low-pass and high-pass filters. The raw data reveal significant deviations due to gyroscope bias and accelerometer noise. Static calibration effectively reduces systematic errors, although residual biases remain. FFT analysis identifies dominant frequency components in each axis, while digital filtering helps eliminate irrelevant frequency noise. Precision testing demonstrates that the sensor produces relatively stable data post-calibration, with the Z-axis showing higher deviation compared to the X and Y axes. The combination of calibration and signal processing methods significantly improves the data quality and reliability of the MPU6050 sensor. This research contributes to the development of more efficient and low-cost AUV navigation systems and supports the broader application of simple IMU sensors in underwater exploration and maritime technologies.
