Research ArticleOpen accessIn the author namesAn 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 author namesBioethanol Production from Graminoid Weeds in Bayero University Kano: A Potential Feedstock for Future Sustainable Aviation Fuel ApplicationsAdam Salihu Kila, Sa’idu Hassan Musa, Umar Aliyu Ahmed et al.This study evaluates the potential of selected graminoid weeds from Bayero University, Kano (BUK), Nigeria, as feedstock for bioethanol production. Ten (10) abundant weed species, including Cenchrus species, Cynodon dactylon, and Setaria barbata, were subjected to physicochemical pretreatment (ultrasonication, hydrothermal treatment, and enzymatic hydrolysis) followed by fermentation using Bacillus subtilis, Saccharomyces cerevisiae, and their co-culture. Pretreatment significantly enhanced reducing sugar … …Energy Research Journal, Vol. 15, Issue 1 · 15 Jul 2026 · 1,170 accessesView PDFCite
