Research ArticleOpen accessIn the abstractAn Adaptive Detail Preserving Modified Progressive Pca Thresholding Based Image DenoisingN. Anilkumar, S. Radhakrishnan, Shaik Syed Basha et al.Radiologists use medical imaging tools to assess the anatomy and function of interior organs. However, medical images are frequently distorted by various types of noise generated during the capture, transmission, and reconstruction operations, which can dramatically reduce image quality and hide critical diagnostic features. As a result, developing effective denoising algorithms that suppress noise while maintaining structural information remains a … …Journal of Computer Science, Vol. 22, Issue 8 · 8 Sep 2026 · 529 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Sweet Sorghum Varieties for Bioethanol Production Under Dryland ConditionsIldar Bogapov, Marden Baidalin, Oksana Kibalnik, Saltanat BaidalinaThe objective of this study was to evaluate the productivity potential and theoretical bioethanol yield of 12 sweet sorghum genotypes under dryland conditions of Northern Kazakhstan during the 2024-2025 growing seasons using a quantitative experimental design. Significant varietal differences in agronomic traits were observed depending on meteorological conditions.
