This study aims to develop a classification strategy over brain wave signals for the accurate control of lower limb exoskeleton during therapy scenario applications. The proposed framework mainly lies on the Intention Matrix, which governs the fusion of obtained data from the exoskeleton sensors and further generates the control signals sent to the lower level. During the generation of class centroids, the Intention wave plays a significant role. In most cases, the value of Intention waves should be the highest to map the user's intention movements correctly. The Intention Matrix successfully modifies the Action Engine by assessing input from the proprioceptive sensors and recommendations from the Mitigator block. Collaboration between the human user and the exoskeleton through intention reading occurs after the user's limb initiation. This principle indicates the preliminary feasibility of the Intention Matrix in supporting the EXOS-1 Skeleton during a therapy scenario.

The acquisition of advanced dental skills typically necessitates extensive practical training. Currently, immersive reality (IR) represents an innovative a

Background: Dental students’ competencies are shaped by their training, yet traditional methods with mannequins often lack the depth necessary for comprehensive understanding, potentially impacting clinical proficiency. Immersive reality (IR) innovatively offers interactive and scenario-based environments that may enhance skill acquisition. Objective: This study evaluates the effectiveness of IR-based training implementation in comparison with conventional training methods for dental extractions. Methods: A prospective multicenter randomized clinical trial was conducted. Students were randomized to either IR-based training on open and closed extractions or conventional hands-on tutorials by oral surgeons. Post training, participants’ satisfaction and understanding were assessed and analyzed. Results: As of September 2025, 60 students from Hasanuddin University, Makassar, and Padjajaran University, Bandung, have been enrolled, and study enrollment will be expanded to Universitas Sumatera Utara, Medan. Data collection is ongoing and will conclude in November 2025, with expected dissemination in early 2026. Conclusions: IR-based training offers a novel approach that may boost motivation, knowledge retention, and skill transfer in dental education. This pilot protocol explores IR’s feasibility and potential to advance dental students’ competencies.

Recently, research about trajectory tracking of autonomous vehicles has significantly contributed to the development of autonomous vehicle technology, particularly with novel control methods. However, tracking a curved trajectory is still a challenge for autonomous vehicles. This research proposes a state feedback linearization with observer feedback to overcome some difficulties arising from such a path. This approach suits a complex nonlinear system such as an autonomous vehicle. This method also has been compared with the linear-quadratic regulator (LQR) method. So, the goal of this research is to improve the control system performance of autonomous vehicles that are stable enough to navigate a curved path. Moreover, the study shows that the developed control law can track the curved path and solve existing problems. However, improvements are still necessary for the vehicle's performance and robustness.

The present study aimed to report a novel developed technology for disinfecting pathogens in aerosols produced by dental health applications. The proposed method was integrated into a disinfection room installed inside an extraoral dental aerosol suction system. The experimental phase was designed to measure the application of the system during dental care management. These experiments assessed the effectiveness of the proposed mechanism in disinfecting captured micro-organisms. The results showed that the system reduced the quantity and coverage area of harmful splatters and aerosols by ∼50%. Future studies should verify the effectiveness of the approach for measuring the temperature inside the disinfection room and the number of pathogens, including coronavirus, that remain after the disinfection process.

Mobile learning is fairly new in the local context, particularly for STEM subjects in Malaysia universities. However, this raises the issue of the ethics of mobile technology. With the advancement of mobile technologies few studies have been conducted for mobile ethics in student-generated activities. The aim of this research is to investigate the impact of mobile learning student-generated activities ethics in Malaysia. The methodology used in this research is largely qualitative with students from a local university in Malaysia. This novel study developed early themes that sign post factors for mobile ethics in student-generated activities in a Malaysian university context for STEM subjects.

This past year in Tellumpoccoe Village has made effective the performance of equipment with hybrid water supply technology through pump wells and automation technology and integrated filtering systems to improve water quality. For household level consumption, a family sample is taken to clean water and provide assistance during the installation process and the feasibility test for filtered water consumption. Besides that, an engineering team of 26 people had formed. With the passage of time the equipment has been able to be used by the community in tellumpoccoe village well until a major flood disaster occurred in early October last year 2018. So that as a result of the flooding the RO equipment was soaked so that it could no longer be used. New problems arise because of the ignorance of the community to improve the tool. So as to overcome these problems, training is conducted to overcome the existing problems so that the equipment can be reused. So that this community service activity was held which aims to provide training on how to maintain and repair (Trouble Shooting) the existing RO system so that villagers will be able to maintain the sustainability of the clean water mechanism.

In this study, a solar pond prototype is used to analyze the temperature and salinity gradients of alternative energy source processes. The study used two types of solar pond to investigate the temperature and salinity of gradients from each solar pond. The first solar pond utilizes sunlight as a heat source that emitted directly on the solar pond and the second solar pond utilizes the spotlights as a direct heat source emitted on the solar pond. The first solar pond is made of a cylindrical plastic tank of 1.05 m tall, 0.8 m in diameter placed outdoors in direct sunlight and the second solar pond model is made of a trapezium plastic tank with a height of 0.9m, the upper diameter 0.54m and a bottom diameter of 0.49m placed indoors with floodlights. The gradient temperature salinity and temperature measurement in the fest solar pond are smaller than temperature in the second solar pond however, the T₃ temperature in the outdoor solar pond is larger than the indoor solar pond. The observation results show that the first solar pond generates the mean value of temperature and salinity of successive gradients 32 (°C); 30 % and the second solar pond has the average value of temperature and salinity of successive gradients 31 (°C); 28 %.
