Review ArticleOpen accessIn the keywordsA Strategic Study on the Environmental Impacts of Wind Turbine Blade Materials, their Improvements, Economics and End-Life-OptionsOjshwi Prakash, Godwin Glivin, N. Kalaiselvan, V. MariappanWind energy is a great alternative to solar energy (During monsoon) along with conventional non-renewable energy sources and has a potential market growing exponentially. Modern 3 Blade HAWTs are most dominant in the market and have high efficiency. Blades are 15 to 20% of the cost of the wind turbine unit and also exposed to the environment. Therefore it is … …Energy Research Journal, Vol. 11, Issue 1 · 13 Nov 2020 · 8,366 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOn Wing Tip Flow Around a Low Aspect Ratio Wing at Low Flight Speeds Using OpenFOAM® and Parallel ProcessingNikolaos Konstantinos Lampropoulos, Ioannis Eleftherios SarrisIn the present study, the effect of the wing tip geometry on the aerodynamic performance of a swept-back wing at moderate Reynolds numbers is investigated through numerical simulation and parallel processing. The aim is the identification of streamlines around the wing and subsequently the formation of the wing tip vortex. Due to the purely three-dimensional character of the flow, the … …Journal of Aircraft and Spacecraft Technology, Vol. 9, Issue 1 · 31 Jan 2025 · 9,538 accessesView PDF Cite

Research ArticleOpen accessIn the abstractWomen in Informal Trade Amidst COVID-19: SOA Market CameroonTlholohelo Mojakisane, Brivery Siamabele, Matildah Kaliba, Rudo Phiri MumbaSARS-CoV-2, which stands for severe acute respiratory syndrome coronavirus 2, became a global health emergency in 2019. Even though the pandemic reached the African continent relatively late in 2020, it had already been terrorizing other parts of the world. In wake of the COVID-19, trade restrictions were imposed and affected the traders across the continent, but the impacts were enormous … …Journal of Social Sciences, Vol. 19, Issue 1 · 19 Jan 2024 · 6,023 accessesView PDF Cite

Research ArticleOpen accessIn the abstractLove in Crisis? How Young Women’s Ideas and Experiences of Intimate Relationships are Reshaped by Conditions of Economic Austerity in GreeceJulia Kazana-McCarthyThis study seeks to examine intimate relationships and attitudes towards such ties, among Greek young women (n = 36). In the wake of challenging structural situations surrounding the effects of economic austerity in Greece, the accounts of these young women are understood with reference to their options on finding and sustaining intimate relationships. It is argued that these accounts are … …Journal of Social Sciences, Vol. 16, Issue 1 · 1 Jan 2021 · 6,496 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEnhanced Channel Estimation and Performance Analysis Using H-Infinity Filter for MIMO-Orthogonal Frequency Division Multiplexing SystemsJoseph Gladwin Sekar, Salivahanan SankarappanThis paper, deals with H-infinity channel estimation technique for Orthogonal Frequency Division Multiplexing (OFDM) systems, in fading channel. Channel estimation is important for wireless applications because, in practical transmission scenario, channel correlation functions are either not known or cannot be easily estimated. It is therefore desirable to have an estimator which is robust to mismatches between the assumed and the … …Journal of Computer Science, Vol. 11, Issue 2 · 29 Jan 2015 · 6,823 accessesView PDF Cite
