Review ArticleOpen accessIn the abstractA Bilingual Advantage on Word Learning-Factors Influence on Lexical Development of BilingualsNing Cao, Guanying ChenLexical development is the changes that occur in vocabulary knowledge. The central role of the lexicon in language and vocabulary development makes it an integral aspect in the study of bilingualism. In recent years, there are many studies on lexical development in bilinguals. By reviewing these related studies, it reveals that the age of acquisition, executive function and early language … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 8 Jul 2020 · 6,987 accessesView PDFCite
Research ArticleOpen accessIn the abstractGender-Based Customer Counting System Using Computer Vision for Retail StoresIntan Sari Areni, Tiwi Nur Safitri, Indrabayu, Anugrayani BustaminThe development of modern retail business is gradually getting faster, increasing the level of competition among retailers. The retailers are changing their business strategies to acquire new customers, maintain customer loyalty and improve customer service. One way to indicate the good market performance of a retail shop is to know the number and details of visitors based on gender.

Research ArticleOpen accessIn the abstractAbout Aircraft's New Power and PropulsionRelly Victoria Virgil Petrescu, Florian Ion Tiberiu PetrescuEven though the current classical methods of aerospace propulsion are much improved, some of the most modern methods have already been introduced, including propulsion with electric motors. Energy can be obtained from hydrogen burners, honeycomb burners to protect the combustion of hydrogen that burns 10 times faster than conventional fuels or alcohols. Hydrogen storage is also done in honeycomb cell … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 1 · 5 Mar 2020 · 7,329 accessesView PDFCite
Research ArticleOpen accessIn the abstractData Warehouse Design to Support Social Media Analysis in a Big Data EnvironmentCarlos Roberto Valêncio, Luis Marcello Moraes Silva, William Tenório et al.The volume of generated and stored data from social media has increased in the last decade. Therefore, analyzing and understanding this kind of data can offer relevant information in different contexts and can assist researchers and companies in the decision-making process. However, the data are scattered in a large volume, come from different sources, with different formats and are rapidly … …Journal of Computer Science, Vol. 16, Issue 2 · 20 Feb 2020 · 8,229 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproved 3D Imaging Performance of AFMMd Sohel RanaOver the last three decades the Atomic Force Microscopy (AFM) has played an important role in the field of nanotechnology for imaging and manipulating samples. However, the acquisition of a high-quality imaging performance by an AFM is significantly influenced by its key scanning element called its Piezoelectric Tube Actuator (PTA). In this article, to improve its performance, a multi-input multi-output … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 28 Jan 2020 · 7,299 accessesView PDFCite
Research ArticleOpen accessIn the abstractNondestructive Assessment of Egg Freshness using a Synchronous Fluorescence Spectral TechniqueJianhu Wu, Guifeng Li, Yankun Peng et al.Freshness is an important index of egg quality. In this study, a synchronous fluorescence spectral technique was employed to determine the freshness of an intact egg. Synchronous fluorescence spectra of intact eggs were acquired using a fluorescence spectrometer supported by a laboratory fluorescence acquisition device and egg freshness (Haugh Unit) was obtained using destructive methods. Eggs feature fluorescence signals were … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 4 · 19 Dec 2019 · 8,135 accessesView PDFCite
Review ArticleOpen accessIn the abstractNovel Approach for Characterizing Solid Rocket Motor (SRM)Aliyu Bhar Kisabo, Ngozi Nwokolo, Aliyu Funmilayo Adebimpe, Sholiyi Olusegun SamuelTo characterize SRM, the motor needs to be tested on a static test rig and certain performers indicators evaluated. In this study, the thrust with time from the SRM was acquired via a Digital Acquisition (DAQ) System and saved in Microsoft Excel® format(.csv). These thrust and time of the tested motor were then imported into MATLAB® for the purpose of … …Journal of Aircraft and Spacecraft Technology, Vol. 3, Issue 1 · 24 May 2019 · 6,457 accessesView PDFCite
Research ArticleOpen accessIn the abstractHybrid, Hybrid Flexible and Fully Online Learning through Students' EyesDolapo Adeniji-Neill, Courtney Lee Weida, Anne MungaiHybrid and fully online studies and classrooms are no longer fringe elements of learning or knowledge acquisition; they have become integral part of learning in the 21st century. Like all modes and styles of learning, they depend on continuous research for best practices in order to remain relevant in terms of effectiveness and growth. This study is a collaboration between … …Journal of Social Sciences, Vol. 14, Issue 1 · 28 Sep 2018 · 8,276 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of the Earth's Surface State by Unsupervised Classification: Case of Vegetated, Aquatic and Mineral SurfacesJean-Claude Okaingni, Sié Ouattara, Adles Kouassi, Alain ClémentIn this study, we propose an unsupervised classification scheme based on the Dempster-Shafer Theory (TDS) and the Dezert-Smarandache Theory (DSmT) to characterize vegetated, aquatic and mineral surfaces. From pre-processed ASTER satellite images (georeferencing, geometric correction and 15 m re-sampling), neo-channels were produced by determining the spectral indices NDVI, MNDWI and NDBaI, considered as sources of information for classification of a … …American Journal of Applied Sciences, Vol. 15, Issue 7 · 27 Aug 2018 · 8,183 accessesView PDFCite
Research ArticleOpen accessIn the abstractOutcomes and Risk Factors Associated with Drug Resistant Tuberculosis in Rural Eastern Cape, South AfricaCarine Bokop Fotso, Sandeep D. Vasaikar, Teke ApalataWith the emergence of Multidrug-Resistant (MDR) and Extensively Drug-Resistant (XDR) strains of Mycobacterium tuberculosis, Tuberculosis (TB) has become an even greater threat in South Africa (SA). The study sought to investigate the resistance pattern of anti-TB drugs in M. tuberculosis as well as to determine the associated risk factors and outcomes for MDR-TB and XDR-TB. A descriptive study was conducted … …American Journal of Infectious Diseases, Vol. 14, Issue 2 · 15 Aug 2018 · 9,537 accessesView PDFCite
