Measurement of powder bed oxygen content by image analysis in laser powder bed fusion

A Comprehensive Review on Sustainability and Environmental Impact of Laser Powder Bed Fusion Additively Manufactured As-Built Ti-6Al-4V Parts

“…One of the primary benefits of L-PBF is its effective utilization of materials, resulting in a reduction of material waste compared to conventional manufacturing techniques [104,107]. L-PBF is a manufacturing technique that employs selective melting of specific regions within the powder bed, thereby reducing material consumption and minimizing waste generation [105]. The statement above presents a clear distinction from subtractive manufacturing methods, which involve the removal of a substantial quantity of material as waste during machining procedures.…”

Analysis and Emotion Recognition of Educational Network New Media Images Based on Deep Learning

“…Although existing research methods have achieved preliminary results in image content analysis and emotion recognition, there are still some shortcomings. Firstly, traditional image content annotation methods often ignore the re-calibration of features when dealing with ENNM images, resulting in inaccurate annotation results [15][16][17][18]. Secondly, in terms of emotion recognition, most existing methods only focus on the judgment of emotion categories, ignoring the recognition of emotion intensity and subtle changes, which fails to meet the high-precision requirements of emotion analysis in educational scenarios [19][20][21].…”
