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 · 5,991 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 · 5,944 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 · 6,429 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeasuring Customers’ Satisfaction Using Sentiment Analysis: Model and ToolAhmed Alqurafi, Tawfeeq AlsanoosyCustomer reviews are a valuable data resource for business owners and companies. Customers frequently write reviews on many platforms, such as eBay or Amazon. These reviews show, for instance, to what extent customers are satisfied with a service or a product. Therefore, these reviews can be used by companies and business owners to improve their services or products. However, numerous … …Journal of Computer Science, Vol. 20, Issue 4 · 7 Feb 2024 · 6,475 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 · 6,098 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. Simulation results … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 6 May 2019 · 7,677 accessesView PDFCite
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).
