    查看更多>>摘要:By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-Data detailed on robotics have been pr esented. According to news reporting originating from Seoul, South Korea, by New sRx correspondents, research stated, "RISC-V offers a modular technical approach combined with an open, royalty-free instruction set architecture (ISA). However, despite its advantages as a fundamental building block for many embedded syste ms, the escalating complexity and functional demands of real-time applications h ave made adhering to response time deadlines challenging." Our news reporters obtained a quote from the research from Seoul National Univer sity of Science and Technology: "For real-time applications of RISC-V, real-time performance analysis is required for various ISAs. In this paper, we analyze th e real-time performance of RISC-V through two real-time approaches based on proc essor architectures. For real-time operating system (RTOS) applications, we adop ted FreeRTOS and evaluated its performance on HiFive1 Rev B (RISC-V) and STM3240 G-EVAL (ARM M). For real-time Linux, we utilized Linux with the Preempt-RT patch and tested its performance on VisionFive 2 (RISC-V), MIO5272 (x86-64), and Rasp berry Pi 4 B (ARM A). Through these experiments, we examined the response times on the real-time mechanisms of each operating system. Additionally, in the Preem pt- RT experiments, scheduling latencies were evaluated by means of the cyclictes t. These are very important parameters for implementing real-time applications c omprised of multi-tasking. Finally, in order to show the real-time capabilities of RISC-V practically, we implemented motion control of a six-axis collaborative robot, which was performed on the VisionFive 2. This implementation provided a comparative result of RISC-V's performance against the x86-64 architecture. Ulti mately, the results indicated that the real-time performance of RISC-V for real- time applications was feasible."

According to news reporting from Taiyuan, People's Republic o f China, by NewsRx journalists, research stated, "Accurate prediction of individ ual tree mortality is essential for informed decision making in forestry." Funders for this research include Shanxi Province Basic Research Program, Youth Science Research Project; Shanxi Province Key Research And Development Program; National Natural Science Foundation of China. The news editors obtained a quote from the research from Shanxi Agricultural Uni versity: "In this study, we proposed machine learning models to forecast individ ual tree mortality within the temperate * * Larix gmelinii* * var. * * principis -rupprechtii* * forests in Northern China. Eight distinct machine learning techn iques including random forest, logistic regression, artificial neural network, g eneralized additive model, support vector machine, gradient boosting machine, k- nearest neighbors, and naive Bayes models were employed, to construct an ensembl e learning model based on comprehensive dataset from this specific ecosystem. Th e random forest model emerged as the most accurate, demonstrating 92.9% accuracy and 92.8% sensitivity, making it the best model among tho se tested. We identified key variables impacting tree mortality, and the results showed that a basal area larger than the target trees (BAL), a diameter at 130 cm (DBH), a basal area (BA), an elevation, a slope, NH4-N, soil moisture, crown density, and the soil's available phosphorus are important variables in the * * Larix Principis-rupprechtii* * individual mortality model. The variable importan ce calculation results showed that BAL is the most important variable with an im portance value of 1.0 in a random forest individual tree mortality model."

    New Robotics Data Have Been Reported by Researchers at University of Applied Sci ences (Fatigue Behaviour of Automatically Hfmi-treated Welds)

    查看更多>>摘要:By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-A new study on Robotics is now availab le. According to news reporting originating from Munich, Germany, by NewsRx corr espondents, research stated, "Due to notches, welds are most critical regarding fatigue failure within cyclic loaded constructions. Therefore, various post-weld -treatment techniques like post-weld treatment by high-frequency mechanical impa ct (HFMI) treatment have been invented to improve the fatigue strength of welded details." Financial support for this research came from Central Innovation Programme for S MEs (ZIM) funded by the Federal Ministry of Economics and Climate Protection (BM WK) (Zentralen Innovationsprogramms Mittelstand (ZIM) Bundesministerium fr Wirts chaft und Klimaschutz (BMWK)). Our news editors obtained a quote from the research from the University of Appli ed Sciences, "The benefit, resulting from HFMI treatment, has already been prove n by numerous studies. Since a manual HFMI treatment must be performed by a skil led and trained person to ensure an acceptable treatment quality, an automated a pplication of HFMI treatment is supposed to result in a more reliable and consis tent treatment result, which does not depend on the operator. Furthermore, a rob otic application of HFMI treatment enables an economic implementation of HFMI tr eatment of automated welded constructions like offshore wind energy converters a nd various mechanical components, as these parts do not have to be taken out of the production chain to manually perform HFMI treatment."
