Research ArticleOpen accessEvery word in the titleComparison and Analysis of Vertical Coherence in the Shallow Water of Two ocean regionV. G. Sivakumar, V. Rajendran, R. SaranyaNoise characteristics at shallow water is highly variable due to wave guide nature of the shallow water environment, reflection of noise from the bottom surface; due to biological activities and also due the sound speed in shallow water vary substantially. Thus noise field characterization is complex in shallow water. The ambient noise data was collected in the shallow water of … …American Journal of Applied Sciences, Vol. 10, Issue 6 · 5 Jun 2013 · 6,488 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTurbo-coding of Coherence Multiplexed Optical PPM CDMA System With Balanced DetectionK. Chitra, V.C. RavichandranThe effects of turbo-coding on the coherence multiplexed optical PPM CDMA systems are shown by evaluating bit error rate (BER) with respect to system parameters such as interleaver length (K), number of simultaneous users (N), code length (f), initial pulsewidth (t0) and normalized threshold (θ) by including the effects of thermal noise and shot noise. Turbo-codes increase the number of … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 6,617 accessesView PDFCite

Research ArticleOpen accessIn the keywordsMental Health Promotion among Nursing StudentsChoochart Deeromram, Amorn Suwannimitr, Suwadee JundeekrayomProblem statement: In the literature, there is no consensus over what constitutes an appropriate model for mental health promotion among nursing students in Thailand. Approach: This quasi-experimental research was conducted to evaluate the effects of mental health promotion intervention. Several activities in this intervention were created for promoting sense of coherence which focused on the manipulation of both internal and … …Journal of Social Sciences, Vol. 6, Issue 2 · 30 Jun 2010 · 9,033 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA New Semantic Cache Management Method in Mobile DatabasesShengfei Shi, Jianzhong Li, Chaokun WangIn mobile database systems, caching is a crucial way to improve the performance because a new query can be partially answered locally when the client is continuously moving around. Semantic caching has been paid much attention in traditional database systems. However, the methods of semantic cache management proposed in those systems are not suitable for mobile computing environment. Moreover, although … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 6,878 accessesView PDFCite
Research ArticleOpen accessIn the keywordsParsing Arabic Texts Using Rhetorical Structure TheoryH. I. Mathkour, A. A. Touir, W. A. Al-SaneaProblem Statement: Processing texts based on rhetorical structure theory has shown interesting results. Rhetorical Structure Theory (RST) improves the ability of extracting the semantic behind the processed text. Different applications such as information retrieval, text summarization, and text generation have proved to give better result using RST. The applicability of RST to process and understand texts has been studied in … …Journal of Computer Science, Vol. 4, Issue 9 · 30 Sep 2008 · 7,389 accessesView PDFCite

Frequency mapping of 105 canonical algorithms identified Particle Swarm Optimization (PSO), Grey Wolf Optimizer (GWO), and Whale Optimization Algorithm (WOA) as the three most recurrent … …Journal of Computer Science, Vol. 22, Issue 2 · 4 Mar 2026 · 2,183 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptiCNN: Local thresholding segmentation and CNN with SVM Approach for Diabetic Retinopathy Detection and Classification of Fundus ImagesAnju Mishra, Mrinal Pandey, Laxman SinghDiabetic Retinopathy (DR) is a progressive eye disease that can lead to vision loss and blindness if left untreated. Ophthalmologists diagnose DR using medical imaging modalities such as fundus photography and optical coherence tomography (OCT); however, manual interpretation of these images is time-consuming and subject to inter-observer variability. While DR is irreversible, vision loss can be prevented through early detection … …Journal of Computer Science, Vol. 21, Issue 10 · 15 Dec 2025 · 2,153 accessesView PDFCite
