Research ArticleOpen accessIn the abstractHybrid Adaptive Filters for Dynamic Mass Measurement of Moving Objects on Flexible PlatformsSergio Bimbi Junior, Flavio Celso Trigo, Agenor de Toledo FleuryDynamic mass measurement of moving objects on flexible platforms remains a significant challenge due to mechanical vibrations, structural flexibility, and the inherently low Signal-to-Noise Ratio (SNR) of strain gauge sensors. Traditional analog filtering approaches, such as Tow– Thomas active filters, exhibit limitations since gain stages propagate and may even amplify intrinsic noise, compromising metrological accuracy. This work proposes a hybrid … …American Journal of Engineering and Applied Sciences, Vol. 19, Issue 1 · 22 Apr 2026 · 2,655 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Lightweight PyBullet-Based Framework for Fast Reinforcement Learning Prototyping on 6-DOF Robotic ArmsNgoc Kim Khanh Nguyen, Anh Thu Mang, Quang NguyenControlling 6-Degree-of-Freedom (6-DOF) robotic arms for precise manipulation tasks is challenging due to kinematic redundancy and the complexity of existing simulation environments like MuJoCo or ROS-Gazebo. This paper presents ArmReach6DOFEnv, a lightweight, open-source simulation framework built on PyBullet for rapid Reinforcement Learning (RL) prototyping on 6-DOF robotic arms. Using a Universal Robot Description Format (URDF) model, the environment supports a … …Journal of Mechatronics and Robotics, Vol. 9, Issue 1 · 11 Feb 2026 · 3,071 accessesView PDFCite
Research ArticleOpen accessIn the abstractA GUI-Enabled, Automated LSTM-Based Inverse Kinematics Pipeline for 6-DOF Robotic Arms Using MATLAB and CoppeliaSimWaleed Abdulrahman Saleh Al-Akwa, Mohammed Abdulwahab Ahmed DabaExisting deep learning-based inverse kinematics (IK) solutions often target specific robotic arms and require significant modifications when applied to different configurations. To support early-phase design and testing of 6-degree-of-freedom (6-DOF) robotic arms, this study presents a fast and adaptable IK solution through a user-friendly interface. Unlike traditional numerical methods that are computationally intensive, sensitive to initial conditions, and may not … …Journal of Mechatronics and Robotics, Vol. 9, Issue 1 · 26 May 2025 · 8,252 accessesView PDFCite
Research ArticleOpen accessIn the abstractYazidi Women in Displacement in Northern Iraq: Gendered Realities and their Impact on Mental HealthKristina Jadranović, Turkiya Shammo et al.This study explores how gendered realities affect the mental health of Yazidi women, currently displaced in Northern Iraq. The aim is to identify positive and negative gender practices, explore their impact on mental health outcomes, and situate them in the cultural and socio-political context of the Yazidi community. The study adopts a mixed methods research design, combining the results of … …Journal of Social Sciences, Vol. 20, Issue 1 · 3 Feb 2025 · 6,887 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalyze and Predict the 2022 World Happiness Report Based on the Past Year's DatasetYifei ZhangThrough the impact of the COVID-19, people around the world have been affected to various degrees. Thus, it is more interesting to compare the happiness reported between 2022/2021 and before 2019. This article concludes 5 years of happiness scores data including family, Gross Domestic Product (GDP), health, freedom, generosity trust, and dystopia residual. Happiness scores are considered appropriate indicators to … …Journal of Computer Science, Vol. 19, Issue 4 · 16 Mar 2023 · 6,913 accessesView PDFCite
Research ArticleOpen accessIn the abstractSingularity Analysis of a Hybrid Serial-Cable Driven Planar RobotSamir Lahouar, Lotfi RomdhaneIn this study, we address the problem of singularities of a hybrid serial-cable driven planar robot. Based on an analytical kinetostatic analysis three types of singularities are determined, i.e., serial, parallel, and combined singularities. In addition, cable tensions should be positive, otherwise, the robot will be uncontrollable. The serial singularity corresponds to positions where the serial port of the robot … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 3 · 26 Sep 2022 · 5,604 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of an Arduino-Based Robotic Arm Yam Heap MakerAgbese Raphael, Dagwa Ishaya Musa, Nurudeen Abdulhakeem Hassan, Adekunle JoshuaIn this study, a prototyperobotic arm yam heap-maker using Arduino was developed. Nigeria produces around75% of global yam production which is widely consumed as staple foods in Africaand Asia and as raw materials for processing into other finished goods. Theproduction of this economic commodity is largely crude and labor-intensive assuch the need to adopt a modern approach to farming.

Research ArticleOpen accessIn the abstractNew Insights into the Pre-Concentration of Alunite from a Siliceous ore using Froth FlotationFahimeh Dehghani, Halimeh Askari-Sabzkoohi, Tathagata GhoshAlunite is the main non-bauxite source of aluminum. Due to the low Degrees Of Freedom (DOF) of alunite, froth flotation, as a pre-concentration method, is a viable alternative to increase selectivity in downstream processes. The current study was aimed at investigating the pre-concentration of alunite using micro-flotation. In the first step, an optical microscope studies were done to determine DOF … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 20 Dec 2020 · 7,176 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhytoremediation and Adsorption of Heavy Industry Emitted from Cement Industry through Plant Leaves, Case Study: Golestan Peivand Cement FactorySoleyman Ghorbanzadeh, Meysam Madadi, Sara Abdollahi, Kaveh Ostad-Ali-AskariCement factories are found to be one of the major causes of pollution. Cement mist and dusts depositions affect the photosynthesis, secretion and fertility of the plant. Increasing the concentration of airborne dust reduces photosynthetic potential in leaves, closes leaf stomatals and, in general, reduces the growth and fertility of plants. The purpose of this study is to determine the … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 23 Nov 2020 · 6,438 accessesView PDFCite
