In the field of wheel mobile robots, researchers focused on learning and developing new algorithms to improve robot capabilities. But the lack of the actual hardware along with expensive costs has limited the study to only simulation. Furthermore, the result from simulation alone cannot conclude the robot’s actual performance in real-time. A plug-and-play robot structure is designed and tested for its function. In addition to that, finite element

DC motor is a device that converts electrical energy into mechanical energy. Nowadays, Permanent Magnet DC (PMDC) motors are used in a variety of settings, including residences, commercial buildings, and the manufacturing industry. PMDC motors are currently being used in many applications ranging from everyday tasks to industrial tasks such as industrial machines, automobiles, and robotic applications. In this paper, we present the parameter esti

Quadcopters or quadrotors have always desired to fly smoothly and stay on their path in order to enhance their application. This better performance can be achieved depending on the accuracy of the data. However, relying purely on sensor data cannot be accepted due to the inaccuracy of measurement, thus state estimation to filter noise out is important. This paper is focused on performance evaluation on quadrotors attitude estimation using Unscent

Natural rubber is a polymeric material composed of hydrocarbon chains possessing high flexibility and green strength making them suitable for various applications including automotives tires, construction materials, and as floor protective materials etc. Special properties of rubber are obtained from compounding with various ingredients one of which is inorganic fillers including carbon black, silica, and clay minerals. The concept of processing

For Hydrological and Meteorological research over Cambodia with sparsed rainfall gauges, reliable rainfall is essential. In this study,12 gridded rainfall datasets with a reasonable spatial resolution including Asian Precipitation Highly Resolved Observational Data Integration Towards Evaluation (APHRODITE), Gridded rainfall Observational Dataset for precipitation and temperature Southeast Asia (SA-OBS), Integrated Multi-gridded rainfall Retrieva

Time series forecasting is a well-established research domain, particularly in finance and econometrics, with a multitude of methods and algorithms proposed to achieve accurate future trend predictions. This study aims to examine the effectiveness of two popular models, ARIMA and LSTM, for predicting trends in gold prices in finance and econometrics. Monthly global gold prices from January 2010 to December 2022 are analyzed, with a training set f

California Bearing Ratio (CBR) value has been widely used to evaluate pavement foundation characteristics. To minimize the effect of human errors, cost, and time for selecting soil subgrade soil for roads, the CBR value can be developed using regression techniques by performing numerous CBR and physical tests considering different soil types. The main objective of this study was to examine the correlation of CBR value with soil properties of road

Non-intrusive load monitoring systems (NILM) have attracted much attention due to their potential contribution to energy savings for individual households. The approach analyzes the load consumption of each device in terms of the total energy consumption of the house. The selection of essential load signatures for load identification expresses a crucial challenge with NILM techniques. Several studies that have been proposed in the literature clai

The study aims to predict the cereals prices trade flows in Cambodia, considering anticipated price fluctuations by using the ARIMA model. The data on cereals price of Cambodia was deseasonalized by the seasonality index (SI) for seasonality, resulting in monthly prices from 2000 to 2021. The target variable was independently smoothed by single exponential smoothing (SES) and Holt-Winters exponential smoothing (HWES) before transforming to the Bo

A Gimbal is a type of instrument used for 3D space orientation control. Over the past decade of research on 3-axis tracking gimbal, many research have been contributing to design and control of the system improving the accuracy and quality of the design.This research aims to develop a control framework for the system making it more user-friendly and more convenient for nondevelopers to use the final product. More specifically, this research focus
