Research ArticleOpen accessIn the abstractA Novel Approach of Satellite Image Enhancement Using DWT Based on 2-Type Fuzzy LogicSurjeet Singh Patel, Vivek Kumar Tamta, Abhilekh Bartwal et al.This study proposes a new approach to enhance the dark and low-contrast satellite images captured under poor illumination. Images are converted from RGB to HSV color space in order to separate the Hue (H), Saturation (S), and luminance (V) components. Enhancement is achieved in saturation and luminance components using Discrete Wavelet Transform (DWT) and 2-type fuzzy logic. DWT breaks the … …Journal of Computer Science, Vol. 19, Issue 9 · 15 Aug 2023 · 5,182 accessesView PDFCite
Research ArticleOpen accessIn the abstractParameters Assessment for Industrial 5G NetworksChristian Mailer, Alex Sandro Roschildt Pinto, Adao BoavaTheFifth Generation of Mobile Networks (5G) will allow low latency to be achievedwhile providing high reliability. This service grade will suit industrialapplications very well since it will allow the integration of a wirelessframework without compromising the determinism of industrial networks.Employing Time-Sensitive Networking (TSN) standards in the 5G architecture iscurrently the best solution to maintain compatibility with existing industrialimplementations and to … …Journal of Computer Science, Vol. 18, Issue 8 · 30 Aug 2022 · 5,989 accessesView PDFCite
Research ArticleOpen accessIn the abstractUnderstanding the Epidemiology of Trypanosoma Evansi Infection in Dogs (Canis lupus familiaris) from Urban Areas of ColombiaJeiczon Elim Jaimes-Dueñez, Ángela Patricia Jiménez-Leaño, Daniela Montenegro-Ayala, Maria Esteban-MendozaTrypanosomaevansi is a protozoan parasite that is the causative agent of the animal disease known as "surra", which affects a wide variety of wild and domestic mammals including humans. This study aimed to evaluate the molecular point prevalence and clinic-epidemiological traits of T. evansi infection in dogs from municipalities of the Metropolitan Area of Bucaramanga (MAB), Santander, Colombia. From 2019 … …American Journal of Animal and Veterinary Sciences, Vol. 17, Issue 2 · 1 Jul 2022 · 5,937 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerception, Frequency and Preference in Livestock-Origin Food Consumption During the COVID-19 Pandemic in IndonesiaEndang Sulastri, Annisa’ Qurrotun A’yunCoronavirus disease 2019 (COVID-19) is a contagious respiratory that produces mild gastrointestinal illness. The infection rate of COVID-19 increases in individuals with low immunity. In an effort to prevent this disease transmission, the Government advocates increasing the immunity level along with consuming healthy and balanced diets. The present study discusses the consumption of livestock-origin foods with high nutrient contents that … …American Journal of Animal and Veterinary Sciences, Vol. 17, Issue 1 · 21 Mar 2022 · 6,425 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Feature Extraction Dual DCT-DWT Image Watermarking Combined with Chaos-Based CryptosystemKumari Rinki, Pushpneel Verma, Tanupriya Choudhury, Bhupesh Kumar SinghAs a result of the emerging technologies such as Internet-of-Things (IoT), data analysis and automation in many aspects of identity, watermarking has become increasingly important. A majority of prior systems focused on watermark embedding and recovery techniques for binary and grey-scale images in one specified region of the cover image, making the system less dependable. This study develops a novel … …Journal of Computer Science, Vol. 17, Issue 10 · 13 Nov 2021 · 6,094 accessesView PDFCite
Research ArticleOpen accessIn the abstractA VF-IMF Cohesion Metric for Object-Oriented ClassesJoy Christy Antony Sami, Umamakeswari ArumugamCohesion in Object Oriented (OO) modules impact reusability, efficiency and complexity of software. OO Programmers are mandated to create software with high cohesion. The testing phase in Software Development Life Cycle (SDLC) is not only concerned about creating error free software but also assess quality of code through software metrics. The metric‘Lack of Cohesion in Methods (LCOM)’ is one of … …Journal of Computer Science, Vol. 16, Issue 4 · 10 Apr 2020 · 8,246 accessesView PDFCite
Research ArticleOpen accessIn the abstractOff-road Vehicle-Induced Substrate Vibrations Are Associated with Strong Declines in Ectomycorrhizal Mushroom Fruiting in Forest EcosystemsLev ShestakovWe conducted a multi-year (2020-2024) control-impact field study in a pine forest of the Moscow Region to assess whether off-road vehicle activity affects the fruiting of two ecologically important ectomycorrhizal fungi, Boletus edulis and Suillus luteus. Substrate vibrations associated with vehicle passage were recorded and characterized by dominant energy in the low-frequency range. Over the study period, abundance in disturbed … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 23 May 2026 · 1,305 accessesView PDFCite
Research ArticleOpen accessIn the abstractA 10GHZ Low-Offset Dynamic Comparator for High-Speed and Lower-Power ADCSBakoune Pierre Hypolite, Wembe Tafo Evariste, Moukengue Imano AdolpheThis paper proposed a design of low-voltage Dynamic Comparator using 90 nm PTM CMOS technology for high-speed and Lower-power Analog to Digital Converter (ADC) applications. The double tail structure is employed as based for design new comparator with positive feedback due to best behavior in low-voltage that allows low delay time; decreases the offset voltage and power dissipation.

Research ArticleOpen accessIn the abstractDirect Sequence and Frequency Hopping Signals Classification Based on Co-Occurrence Matrix and Clustering TechniquesHaidy S. Fouad, Hend A. Elsayed, Shawkat K. GirgisSpread Spectrum techniques (SS) were first developed for military applications, but currently, they have commercial applications. SS provides secure communication and allows multiple accesses for same radio spectrum. So, most Wireless Local Area Network (WLAN) systems use it, as do Cognitive Radios (CR), space systems and Global Positioning Systems (GPS). Direct Sequence Spread Spectrum (DSSS) and frequency hopped spread spectrum … …Journal of Computer Science, Vol. 15, Issue 1 · 10 Jan 2019 · 8,203 accessesView PDFCite
