Research ArticleOpen accessIn the abstractModelling IoT Systems with UML: A Case Study for Monitoring and Predicting Power ConsumptionMarla Teresinha Barbosa Geller, Anderson Alvarenga de Moura MenesesSoftware Engineering has evolved to meet the growing complexity of current systems and the resources of the Unified Modeling Language (UML) enable the modeling of such systems in different views. The Internet of Things (IoT) paradigm appears with very peculiar characteristics such as the heterogeneity of its physical and virtual components that must be integrated. Designing systems of this nature … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 1 Feb 2021 · 8,363 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Experiment on Rotary Cutting Test Bench for Sweet Potato VineGuizhi Mu, Zhengduo Liu, Junming Liu et al.In order to study the cutting mechanism of sweet potato vine, provide technical support and theoretical basis for the development of sweet potato vine harvesting machinery and improve the resource utilization rate of sweet potato vine, a cutting test bench for sweet potato vine was designed. The test bench consists of two parts: Mechanical part and measurement-control part. In this … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 1 · 21 Mar 2022 · 5,838 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Empirical Investigation of the Pollution Haven-Halo Nexus in Eastern and Southern AfricaPaul KauluThis study looks into the relationship between trade and pollution in Eastern and Southern Africa from 1977 to 2016. This timeframe is particularly relevant as it was marked by rising CO₂ emissions despite major climate agreements such as the Kyoto Protocol (1997), Reducing Emissions from Deforestation and Forest Degradation (REDD+, 2007), as well as the Paris Agreement (2015). Using time-series … …American Journal of Environmental Sciences, Vol. 21, Issue 1 · 28 Jan 2026 · 2,924 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of Oil Film Shape on Piston Ring and Liner Tribology Under Mixed LubricationAbbas Razavykia, Cristiana Delprete, Eugenio Brusa, Yaser HosseiniMechanical power loss reduction at lubricated reciprocating and rotating components is recognized as an approach to improve the efficiency and to reduce the emissions of Internal Combustion Engines (ICEs). To achieve these goals, the instantaneous investigation of lubrication characteristics is required. Piston ring pack is of paramount importance as it is known as major contributor to frictional losses and energy … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 4 · 10 Nov 2021 · 6,533 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of a Hybrid Power Module for Mobile Wireless Sensor Networks: Towards a Livestock Tracking and Identification SystemMolaletsa Namoshe, Oduetse Matsebe, Obakeng MaphaneSmart technology and Internet of Things (IoT) applications have gained popularity in the development of agricultural systems with Wireless Sensor Networks (WSNs) increasingly becoming the building blocks for IoT applications. However, WSNs have a limited power supply. As a result, these systems have a short lifespan, limited memory and low computing power. This paper describes the development of a hybrid … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 23 Oct 2017 · 7,772 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Permutation Test for Comparing Two Correlated Receiver Operating Characteristic CurvesOkeh Uchechukwu Marius, Onyeagu SidneyThe area under the Receiver Operating Characteristic (ROC) curve (AUC) is a summary measure when comparing two ROC curves. However, this summary measure is less informative when two ROC curves cross and have the same AUCs. In order to detect differences between ROC curves and to be able to tackle the problem of exchangeability of the labels between two diagnostic … …Journal of Mathematics and Statistics, Vol. 16, Issue 1 · 24 May 2020 · 8,132 accessesView PDFCite
Review ArticleOpen accessIn the abstractExploitation of Battery Energy Storage in Load Frequency Control -A Literature SurveyAhmed Zurfi, Jing ZhangDeregulation of the electricity market and the continued attempts by the international community to reduce the effects of global climate change have resulted in a rapid increase in the usage of different renewable forms of energy such as the wind and solar energy. The availability of such renewables is highly sporadic in nature. Consequently, their integration into the power system … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 17 Dec 2016 · 8,139 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign Maximum Power Point Tracking (MPPT) on Photovoltaic Panels using Fuzzy Logic MethodAhmad Faizal, Sutoyo, Mulyono et al.Solar energy is a clean energy, renewable, and available for the long term. The tool used to convert the energy generated from the intensity of sunlight into electricity is photovoltaic panels. However, due to the high cost and low efficiency, the use of the energy is still kind small compared to other types of energy sources. Thus, the need for … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 10 Aug 2016 · 8,503 accessesView PDFCite
Research ArticleOpen accessIn the abstractModel Identification and Wall-Plug Efficiency Measurement of White LED ModulesAhmed Zurfi, Jing ZhangIn this study, an experimental method is developed to measure the Wall-Plug efficiency of white LED modules without using any apparatus or sensors to measure the intensity of light. The tested LED module consists of a white LED chip-on-board affixed on a heatsink. The proposed method is mainly based on thermal and electrical models of the LED module. Measurements of … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 15 Jun 2016 · 8,296 accessesView PDFCite
