Research ArticleOpen accessIn the abstractKnowledge, Attitude and Perception of Smallholder Farmers on Corona Virus Pandemic in NigeriaObot Akaninyene, Ozor Maurice, Nwankwo Temple, Obiekwe NgoziAgriculture plays an essential role in the economy of Nigeria as it provides food for the entire population of a country and also provides raw materials for the non-agriculture sectors of the economy. Nigeria's agriculture is made up of a higher percentage of smallholder farmers who are often exposed to shocks and have less capacity to combat the impact and … …American Journal of Agricultural and Biological Sciences, Vol. 17, Issue 1 · 18 Jun 2022 · 7,071 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Visible and Near Infrared Polarized Lights on Spoofing Face DetectionAzim Zaliha Abd AzizFace spoofing countermeasure is vital to avoid an imposter from gaining access to security biometric systems by using face masks in various forms that mimic a valid user face. Recently, several studies have shown the ability of visible polarized light in distinguishing real and fake faces. In this paper, polarization imaging systems using visible and near infrared (NIR) are proposed … …Journal of Computer Science, Vol. 15, Issue 2 · 23 Feb 2019 · 7,893 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Improvement of SNP Search Using Multithread ProgrammingGeraldo Francisco Donegá Zafalon, Álvaro Magri Nogueira da Cruz, Anderson Rici Amorim et al.Pattern recognition is an important field in Bioinformatics and a well-known task is the search for Single Nucleotide Polymorphism (SNP). It is possible to search for a known SNP position and analyze it using patterns of DNA bases, called masks. Nonetheless, this process becomes computationally expensive as the amount of available genomic data increases. Thus, in this study, we have … …Journal of Computer Science, Vol. 14, Issue 11 · 7 Nov 2018 · 7,734 accessesView PDFCite
Research ArticleOpen accessIn the abstractPERFORMANCE OF TOPOLOGY AWARE RELIABLE ROUTING PROTOCOL FOR LARGE SCALE VIRTUAL PRIVATE NETWORKJayanthi Gokulakrishnan, V. Thulasi BaiA network which merges the usage of the public and the private networks and uses security software for the purpose of compressing, encrypting and masking the digital packets that are being transmitted in the network is called as Virtual Private Network (VPN). In VPN, the communication between the user ends is maintained such that it appears as if the source … …Journal of Computer Science, Vol. 10, Issue 9 · 23 Jun 2014 · 6,662 accessesView PDFCite
Research ArticleOpen accessIn the abstractSharp Transition Multiband Filter in Speech Processing Scheme for Hearing ImpairedJoseph X. Rodrigues, Lucy J. Gudino, K. R. PaiProblem statement: A simple analytical approach to the synthesis of a sharp transition, linear phase, multiband FIR filter is presented. The filter magnitude response is modeled using trigonometric functions of frequency. Approach: Employing variable density of ripple cycles in passband and stopband regions with large density of ripples cycles at the sharp transition edges, reduces the abrupt discontinuities at these … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 27 Feb 2012 · 9,038 accessesView PDFCite
Research ArticleOpen accessIn the abstractShakespeare and Literacy: A Case Study in a Primary ClassroomGeorge BelliveauProblem statement: Childhood is an integral time for literacy development and the aim of this article is to closely examine what pedagogical strategies were most effective to promote literacy learning with a group of six to nine year old children. This case study investigates how the use of specific literacy and drama-based strategies prepared and stimulated young children’s understanding and … …Journal of Social Sciences, Vol. 8, Issue 2 · 18 Feb 2012 · 9,335 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreparation-Properties Relation of Mn-Cu Hopcalite CatalystArdita Mele, Ilo Mele, Altin MeleProblem statement: The Mn-Cu hopcalite catalyst was used for the conversion of CO to CO2 at low temperatures. It was the catalyst of choice in the gas masks for respiratory protection in mines, aircrafts, military, spatial laboratories. Approach: The efficiency of hopcalite catalyst depends on its surface parameters. Its surface characteristics can be influenced from the chosen way of the … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 26 Dec 2011 · 7,888 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpecification of Dynamic Time Series Model with Volatile-Outlier Input SeriesT. A. Lasisi, D.K. Shangodoyin, O. O. Sangodoyin et al.Problem statement: This study considers the precision of the output series generated from aberrant input series in the context of the distribution of the dynamic estimate and also investigate relative merit of analyzing residuals with outliers for a volatility input dynamic model. Approach: The study developed a methodology for checking volatility at every time point and evaluates the influence of … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 1 Oct 2011 · 7,102 accessesView PDFCite
Research ArticleOpen accessIn the abstractLocally-Chosen versus State-Mandated Success Criteria: A Retrospective Evaluation of the Effectiveness of the Success-For-All Program with Fourth and Seventh Grade Hispanic StudentsJames Carifio, Dalis DominguezProblem statement: This study compared the growth in reading competencies of Hispanic female and male students in the SFA program as measured by the Massachusetts Comprehensive Assessment System (MCAS) and the Scholastic Reading Inventory (SRI). Approach: The study was a retrospective study with several a priori hypotheses and examined logical comparison groups of 4th and 7th graders, who received 1 … …Current Research in Psychology, Vol. 1, Issue 2 · 31 Dec 2010 · 7,983 accessesView PDFCite
Research ArticleOpen accessIn the abstractLand Cover Change Detection Using Texture AnalysisXiaofeng Wu, Fen Yang, Roly LishmanProblem statement: It is an important task to detect land cover changes from remotely sensed data for environmental monitoring. Although there are some applications of visual textures to the land use, they are limited to a few land cover categories with the application of one texture measure. Since land cover types are complex and often the integration of various objects, … …Journal of Computer Science, Vol. 6, Issue 1 · 31 Jan 2010 · 8,198 accessesView PDFCite
