Research ArticleOpen accessIn the abstractClassifying and Predicting Students’ Performance using Improved Decision Tree C4.5 in Higher Education InstitutesMohammed Hikmat Sadiq, Nawzat Sadiq AhmedStudents’ information in higher education institutions increases yearly. It is hard for them to extract meaningful information from the huge amount of data manually. Such information can support academic staff to stop students from dropping out at the end of courses. This can be done by evaluating the students’ performance for the course and also by predicting their performance in … …Journal of Computer Science, Vol. 15, Issue 9 · 12 Sep 2019 · 9,168 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Extract Region of Interest in High-Resolution Palmprint using 2D Image Histogram Entropy FunctionInass Shahadha Hussein, Shamsul Bin Sahibuddin, Md Jan Nordin, Nilam Nur AmirThe segmentation of high-resolution palmprint is has been challenged and the research in this filed is still limited because of variations in location and distortion of these images. To achieve superior recognition result, accurate segmentation of a region of interest is very crucial. Therefore, in this paper, a novel palmprint extraction method has been presented using a 2D image histogram … …Journal of Computer Science, Vol. 15, Issue 5 · 8 May 2019 · 7,652 accessesView PDFCite
Research ArticleOpen accessIn the abstractOnline Handwritten Physics Expression Recognition Using a CRNN-LSTM ApproachUjwala Pritam Kolte, Sachin Arun NaikOptical Character Recognition (OCR) is crucial for identifying and extracting information from scientific documents. However, recognizing online handwritten physics expressions remains a relatively unexplored area of research. In the existing literature, most of the researchers worked on CNN classification to identify mathematical expressions. The traditional Convolution Neural Network (CNN) has limitations for extracting sequential data. This study proposes a CRNN … …Journal of Computer Science, Vol. 21, Issue 2 · 31 Dec 2024 · 4,812 accessesView PDFCite
Research ArticleOpen accessIn the abstractDehazing Mechanism Using Auto-Encoder with Intensity Attention SystemRajat Tiwari, Bhawna Goyal, Ayush DograIn the modern world, images play a significant medium for communication. Primarily, it is easily transferred and disseminated across various platforms which allows the people to express their ideology and perceptions. Conversely, images can be prone the environmental conditions as the image quality can be affected by the weather circumstances. Particularly, haze images minimize the whole clarity and visibility of … …Journal of Computer Science, Vol. 20, Issue 12 · 25 Nov 2024 · 4,513 accessesView PDFCite
Research ArticleOpen accessIn the abstractCardiovascular Diseases Identification Using Wavelet Optimization and Modify Cuckoo Search AlgorithmBanit Negi, Abhilekh Bartwal, Agya Ram Verma et al.The problem the author aims to solve is the extraction of discriminatory features in ECG (Electrocardiogram) signals for classification purposes. The scope of the work is to propose a new method for building wavelets that best reflect the discriminatory capacity of ECG signals. The approach involves optimizing the wavelets specifically for the classification function under consideration. To address the problem, … …Journal of Computer Science, Vol. 19, Issue 8 · 3 Aug 2023 · 5,403 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Differentiated Nitrogen Fertilization using Satellite Navigation Systems on the Spring Wheat (Triticum aestivum L.) Crop Yield in the Conditions of Chernozem-Like Soils in the Northern Forest Steppe of the Tyumen Region of RussiaAltynay Oxukbayeva, Nikolai Abramov, Marden Baidalin, Sergei SemizorovSoil cultivation without layers turnover impeded the process of nitrate nitrogen accumulation compared with plowing. The traditional scheme of mineral fertilization applying the averaged standard did not create a heterogeneous level of nutrient supply in primary soil cultivation systems. These factors set them in unequal conditions by default in terms of nitrogen supply to crops. Solid mineral fertilization with the … …OnLine Journal of Biological Sciences, Vol. 23, Issue 1 · 16 Jan 2023 · 5,201 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of SVM-RBF Kernel Space Parameter to Optimize Accuracy Value of Indonesian Batik Images ClassificationAvinanta Tarigan, Dewi Agushinta, Adang Suhendra, Fikri BudimanImage retrieval using Support Vector Machine (SVM) classification verydepends on kernel function and parameter. Kernel function used by dot productsubstitution from old dimension feature to new dimension depends on imagedataset condition. In this research, parameter of Gaussian /Radial BasisFunction (RBF) kernel function is optimized using multi class non-linear SVMmethod and implemented to training and test datasets of traditional Indonesian batik … …Journal of Computer Science, Vol. 13, Issue 11 · 23 Oct 2017 · 7,530 accessesView PDFCite
Research ArticleOpen accessIn the abstractProducing Functional Fatty Acid DHA from Corn Steep Liquor by Aurantiochytrium SW1Xiaojie Ren, Qi Yan, Baoyue Liu et al.Thraustochytrium has a relatively high lipid content in the cell and its lipid content can account up to 70% of the dry cell weight. It is an important raw material for the third-generation biodiesel production and the production of functional fatty acid Docosahexaenoic Acid (DHA). However, the high cost of traditional fermentation medium has hindered the industrial production of lipid. … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 4 · 20 Nov 2021 · 6,323 accessesView PDFCite
Case ReportOpen accessIn the abstractAnamorphic Cartograms and Environmental Risk AnalysisChiara Porporato, Tamara Bellone, Francesco FiermonteBoth Geography and Statistics use graphical representations. Information Technology has enhanced the visualization of data, beyond the traditional aspects, to such an extent that we can nowadays speak of an "image society". Traditional thematic mapping also shows transformations of a variable over time, linking the geographical datum to the time variable. For some decades now a number of cartograms have … …American Journal of Environmental Sciences, Vol. 12, Issue 6 · 12 Dec 2016 · 7,052 accessesView PDFCite
Research ArticleOpen accessIn the abstractPoetry Classification Using Support Vector MachinesShahrul Azman Noah, Noraini Jamal, Masnizah MohdProblem statement: Traditional Malay poetry called pantun is a form of art to express ideas, emotions and feelings in the form of rhyming lines. Malay poetry usually has a broad and deep meaning making it difficult to be interpreted. Moreover, few efforts have been done on automatic classification of literary text such as poetry. Approach: This research concerns with the … …Journal of Computer Science, Vol. 8, Issue 9 · 8 Aug 2012 · 8,871 accessesView PDFCite
