According to news reporting from West Lafayette, Indiana, by NewsRx journalists, research stated, "With the increasing adoption of autonomous mobile robots in the construction industry, accurate localization and mapping in dynamic construction environments have become paramount. This is typically tackled via Simultaneous Localization and Mapping (SLAM) techniques." The news correspondents obtained a quote from the research from Purdue University, "Primarily designed for static environments, traditional SLAM systems struggle to maintain robustness and accuracy in dynamic settings. To address this challenge, this study presents an enhanced visual SLAM system specifically tailored for dynamic construction environments. The proposed system, named vSLAM-Con, introduces an adaptive dynamic object segmentation method, utilizing an innovative AD-keyframes selection mechanism grounded on optical flow magnitude to diminish computational overhead while preserving competitive tracking accuracy. Additionally, a semantic-based feature update process is developed, leveraging scene understanding and continuous observation to augment the reliability of tracking features. This system's performance, evaluated on both an established public benchmark and a custom construction dataset, shows substantial improvements over the baseline and competitive results with the state-of-theart algorithms. More importantly, it largely reduces the processing time compared to state-of-the-arts, demonstrating robust tracking performance even under highly dynamic conditions."

According to news originating from Beijing, People's Republic of China, by NewsRx editors, the research stated, "Due to their roles as efficient lateral force-resisting systems, reinforced concrete shear walls exert a tremendous degree of influence on the overall seismic performance of buildings." Funders for this research include Beijing Natural Science Foundation; Special Funding of China Academy of Building Research. Our news journalists obtained a quote from the research from China Academy of Building Research: "The ability to predict the boundary transverse reinforcement of shear walls is critical to the seismic design process, as well as in the overall evaluation and retrofitting of existing buildings. Contemporary empirical models attain low predictive accuracy, with an inability to capture nonlinearity between boundary transverse reinforcement and different influencing variables. This study proposes a boundary transverse reinforcement prediction model for shear walls with boundary elements based on the demand of ductility. Using the extreme gradient boosting machine learning algorithm and 501 samples, some 52 input variables are considered, and a subset with six features is selected, monitored, and analyzed using both internal methods (gain and cover) and external methods. The results (R2=0.884) display superior predictive capacity compared with existing models. Interpretation and error analysis are performed."

According to news reporting originating in Nanning, People's Republic of China, by NewsRx journalists, research stated, "To provide a reliable, low-cost screening model for preeclampsia, this study developed an early screening model in a retrospective cohort (25,709 pregnancies) and validated in a validation cohort (1760 pregnancies). A data augmentation method (a-inverse weighted-GMM + RUS) was applied to a retrospective cohort before 10 machine learning models were simultaneously trained on augmented data, and the optimal model was chosen via sensitivity (at a false positive rate of 10%)."

According to news reporting originating from Novi Sad, Serbia, by NewsRx correspondents, research stated, "Precision viticulture systems are essential for enhancing traditional intensive viticulture, achieving high-quality results, and minimizing costs." The news journalists obtained a quote from the research from University of Novi Sad: "This study explores the integration of Unmanned Aerial Vehicles (UAVs) and artificial intelligence in precision viticulture, focusing on vine detection and vineyard zoning. Vine detection employs the YOLO (You Only Look Once) deep learning algorithm, achieving a remarkable 90% accuracy by analysing UAV imagery with various spectral ranges from various phenological stages. Vineyard zoning, achieved through the application of the K-means algorithm, incorporates geospatial data such as the Normalized Difference Vegetation Index (NDVI) and the assessment of nitrogen, phosphorus, and potassium content in leaf blades and petioles. This approach enables efficient resource management tailored to each zone's specific needs. The research aims to develop a decision-support model for precision viticulture. The proposed model demonstrates a high vine detection accuracy and defines management zones with variable weighting factors assigned to each variable while preserving location information, revealing significant differences in variables."

According to news reporting originating from the University of Economics by NewsRx correspondents, research stated, "The paper presents three position controller designs for a mobile robot. The first is a position controller using a classic PID controller." Our news correspondents obtained a quote from the research from University of Economics: "The second is the position controller is designed based on optimal three coefficients for PID controller by fuzzy logic control (FLC). The last, the mobile robot is moved according to the trajectories set by the FLC controller. All three controllers have two state variables (position error and position deviation derivative and one output variable, velocity) and one velocity output variable of the robot. The robot is moved according to the trajectories set based on the PID-FLC controller flow fuzzy rules with a 7x7 matrix to the optimal three coefficients of the PID controller. Meanwhile, the FLC controller is done by a 9x9 matrix rule. Evaluated the efficiency of PID-FLC and FLC controllers are compared to classical PID controllers."
