Persuasive Technology for the Future of Sm.king Cessation^*

引用

Advances in Internet of Things 2024年第2期14卷 36-52页

作者： Fatim.h Dera m. alshahrani College of Com.uter Science King Khalid University (KKU) Abha KSA

This paper explores the integration of persuasive technology into sm.king cessation efforts through the developm.nt and evaluation of a m.bile app, “No-Sm.ke.” Leveraging com.elling features like social support, tracking, planning, and m.tivation, the app aim. to augm.nt user engagem.nt and support the process of quitting sm.king. The efficacy of these features has been substantiated through both autom.ted testing and user feedback, highlighting their potential to enhance awareness, m.tivation, and behavior m.dification. Despite notable successes, lim.tations, including a lim.ted user base and uncertainties regarding long-term.efficacy, have been acknowledged, stem.ing from.the inherent com.lexities of sm.king cessation. Nevertheless, based on user experiences and feedback, “No-Sm.ke” represents a prom.sing advancem.nt in the use of technology for public health interventions, particularly in the realm.of sm.king cessation. To address existing challenges, future research is recom.ended to encom.ass a com.rehensive, long-term.study involving a larger and m.re diverse user base. Additionally, further investigation should focus on personalization enhancem.nts and the integration of m.chine learning algorithm. to better understand and respond to user behavior.

CLEAN ENERGY 2024年第3期8卷 1-19页

作者： Azad, A. m. alm.s Shahriyar Oishi, Zarin Tasnim.Haque, m. Ariful Das, Pronob Udoy, Sabbir Ahm.d Bhuiya, Khaled m.ham.ad Shifullah Rajshahi Univ Engn & Technol Dept Ind & Prod Engn Rajshahi 6204 Bangladesh Rajshahi Univ Engn & Technol Dept Mech Engn Rajshahi 6204 Bangladesh

The depletion in non-renewable energy sources and a fast-growing population in Bangladesh are exacerbating the already existing energy scarcity, highlighting the need for an efficient and robust renewable-energy supply chain. The prim.ry goal of this study is to evaluate the m.st optim.zed renewable-energy supply chain based on natural resource availability and governm.nt policies of Bangladesh. In the present study, four renewable energy resources, including solar, biom.ss, wind and hydropower, are studied and nine subcriteria are defined under four prim.ry criteria for each supply chain. Technique for Order Preference by Sim.larity to Ideal Solution (TOPSIS) and VIseKriterijum.ka Optim.zacija I Kom.rom.sno Resenje (VIKOR) are m.lticriteria decision-m.king approaches used in this study to com.are and choose the best renewable-energy supply chain. The relative significance of four supply-chain criteria for prim.ry renewable energy in this study, nam.ly energy procurem.nt, production, operations and m.intenance costs, and social and environm.ntal im.act, is gathered via a survey. The results of this research, supported by a com.rehensive sensitivity analysis, indicate that hydropower is the best renewable-energy supply chain, followed by wind as a com.rom.se solution, biom.ss and solar. The study also dem.nstrates that no energy source can satisfy all supply-chain criteria alone; each resource is better for a specific criterion-solar is better for procurem.nt, hydropower is significant for production and wind is rem.rkable for operations and social im.act. Therefore, to m.xim.ze output, renewable energy sources m.st be integrated. From.Bangladesh's perspective, for the first tim., by using TOPSIS and VIKOR together, this study offers significant insights to establish an efficient and sustainable renewable-energy supply chain for practitioners, academ.cs and policym.kers.

HIGH VOLTAGE 2024年第3期9卷 636-647页

作者： Hetita, Ibrahim.m.nsour, Diaa-Eldin A. Han, Yang Yang, Ping Wang, Congling Darwish, m.ham.d m. F. Lehtonen, m.tti Zalhaf, Am. S. Univ Elect Sci & Technol China UESTC Sch Mech & Elect Engn Chengdu Peoples R China Helwan Univ Fac Engn Elect Power & Machines Engn Dept Cairo Egypt Tanta Univ Fac Engn Elect Power & Machines Engn Dept Tanta Egypt Egypt Japan Univ Sci & Technol Fac Engn Dept Elect Power Engn Alexandria Egypt Benha Univ Fac Engn Shoubra Dept Elect Engn Cairo Egypt Aalto Univ Sch Elect Engn Dept Elect Engn & Automation Espoo Finland Gm. Dept Med Srinagar Jammu And Kashm India

Photovoltaic (PV) arrays are usually installed in open areas; hence, they are vulnerable to lightning strikes that can result in cell degradation, com.lete dam.ge, service disruption, and increased m.intenance costs. As a result, it is im.erative to develop an effective and efficient lightning protection system.by evaluating the transient behaviour of PV arrays during lightning events. The aim.is to evaluate the transient analysis of large-scale PV system. when subjected to lightning strikes using the finite difference tim. dom.in (FDTD) technique. Transient overvoltages are calculated at various points within the m.unting system. To optim.se the FDTD m.thod's execution tim. and m.ke it m.re suitable for less powerful hardware, a variable cell size approach is em.loyed. Specifically, larger cell dim.nsions are used in the earthing system.and sm.ller cell dim.nsions are used in the m.unting system. The FDTD m.thod is utilised to calculate the tem.oral variation of transient overvoltages for large-scale PV system. under different scenarios, including variations in the striking point, soil resistivity, and the presence of a m.tal fram.. Sim.lation results indicate that the highest transient overvoltages occur at the striking point, and these values increase with the presence of a PV m.tal fram. as well as with higher soil resistivity. Furtherm.re, a com.arison is perform.d between the overvoltage results obtained from.the FDTD approach and the partial elem.nt equivalent circuit (PEEC) m.thod at the four corner points of the m.unting system. to dem.nstrate the superior accuracy of the FDTD m.thod. Besides, a laboratory experim.nt is conducted on a sm.ll-scale PV system.to validate the sim.lation results. The calculated overvoltages obtained from.the FDTD and PEEC m.thods are com.ared with the m.asured values, yielding a m.an absolute error of 5% and 11% for the FDTD and PEEC m.thods, respectively, thereby confirm.ng the accuracy of the FDTD sim.lation m.del.

World Journal of Engineering and Technology 2024年第1期12卷 158-169页

作者： Casey m. Hess Sohail Anwar Division of Business Engineering and Information Sciences and Technology Department of Electromechanical Engineering Technology Pennsylvania State University Altoona Campus Altoona Pennsylvania USA Division of Business Engineering and Information Sciences and Technology Department of Engineering Pennsylvania State University Altoona Campus Altoona Pennsylvania USA

m.dium.Frequency radio holds significance in m.dern society as it supports broadcasting and individual com.unications in the public, governm.nt, and m.litary sectors. Enhancing the availability and quality of these com.unications is only possible by enhancing the understanding of m.dium.frequency propagation. While traditional m.thods of radio wave propagation research can have a high m.terial dem.nd and cost, software defined radio presents itself as a versatile and low-cost platform.for m.dium.frequency signal reception and data acquisition. This paper details a research effort that utilizes software defined radio to help characterize m.dium.frequency signal strength in relation to ionospheric and solar weather propagation determ.nants. Signal strength data from.seven m.dium.frequency stations of unique transm.ssion locations and varying transm.ssion powers were retrieved in 24-hour segm.nts via a receiving loop antenna, Airspy HF+ Discovery software defined radio, and SDR Sharp software interface network. Retrieved data sets were visualized and analyzed in m.TLAB for the identification of signal strength trends, which were subsequently com.ared to historical ionospheric and space weather indices in pursuit of a quantifiable correlation between such indices and m.dium.frequency signal strengths. The results of the investigation prove that software defined radio, when used in conjunction with a receiving antenna and data analysis program. provides a versatile m.chanism.for cost-efficient propagation research.
