Journal ArticleDOI
Recent advancements and challenges in Solar Tracking Systems (STS): A review
TL;DR: In this paper, the authors review the most commonly used solar trackers and identify the systems that offer benefits such as greater efficiency, greater tracking accuracy, easy installation and cost effectiveness.
Journal ArticleDOI
Advances, limitations and prospects of nondestructive testing and evaluation of thick composites and sandwich structures: A state-of-the-art review
Walter Nsengiyumva,Shuncong Zhong,Shuncong Zhong,Jiewen Lin,Qiukun Zhang,Zhong Jianfeng,Yuexin Huang +6 more
TL;DR: In this article, the authors review the recent advances in nondestructive testing and evaluation (NDT&E) as applied to the inspection of thick composite parts and sandwich structures and determine possible research prospects to address the limitations of current technologies.
Journal ArticleDOI
Thin thermally grown oxide thickness detection in thermal barrier coatings based on SWT-BP neural network algorithm and terahertz technology.
TL;DR: In this study, an SWT-BP algorithm combining a stationary wavelet transform and a backpropagation (BP) neural network was proposed, and it demonstrated that the proposed algorithm was able to achieve a thickness prediction of up to 1-29 µm of the TGO.
Journal ArticleDOI
Concentrated Solar Power and Photovoltaic Systems: A New Approach to Boost Sustainable Energy for All (Se4all) in Rwanda
Noel Hagumimana,Jishi Zheng,Godwin Norense Osarumwense Asemota,Jean De Dieu Niyonteze,Walter Nsengiyumva,Aphrodis Nduwamungu,Samuel Bimenyimana +6 more
TL;DR: In this article, the authors conducted a SWOT analysis for concentrated solar power (CSP) and photovoltaic (PV) systems in Rwanda and concluded that the off-grid PV microgrid system for the rural community is the most cost-effective because of its low net present cost (NPC).
Journal ArticleDOI
Standalone and Minigrid-Connected Solar Energy Systems for Rural Application in Rwanda: An In Situ Study
Kuo-Chi Chang,Kuo-Chi Chang,Noel Hagumimana,Jishi Zheng,Godwin Norense Osarumwense Asemota,Jean De Dieu Niyonteze,Walter Nsengiyumva,Aphrodis Nduwamungu,Samuel Bimenyimana +8 more
TL;DR: In this paper, the authors developed a cost-effective power generation model for a solar PV system to power households in rural areas in Rwanda at a reduced cost by developing efficient and low-cost off-grid PV systems.
