Research ArticleOpen accessEvery word in the titleExperimental Investigation of Single Pass, Double Duct Photovoltaic Thermal (PV/T) Air Collector with CPC and FinsM. Ebrahim Ali Alfegi, Kamaruzzaman Sopian, Mohd Yusof Hj Othman, Baharudin Bin YatimThe temperature of photovoltaic modules increases when it absorbs solar radiation, causing a decrease in efficiency. This undesirable effect can be partially avoided by applying a heat recovery unit with fluid circulation (air or water) with the photovoltaic module. Such unit is called photovoltaic/thermal collector (pv/t) or hybrid (pv/t). An experimental investigation of a solar air heater with photovoltaic cell … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 6,992 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExperimental Investigation Of Polymeric Compound Cross Section SpringsMayas Al-Mahasne, Tareq A. Abu ShreehahThis paper presents an experimental investigation of the characteristic of the compound cross section springs on models made from polymeric materials (organic glass). Two constructive variants of the compound spring sections were specified with the help of criteria of similarity. The criterion of similarity of natural and model springs was determined by the simulation method at particular spring deflection. The … …American Journal of Applied Sciences, Vol. 4, Issue 1 · 30 Apr 2007 · 6,758 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExperimental Evaluation of Anti-Stripping Additives Mixing in Road Surface Pavement MaterialsTienfuan Kerh, Yu-Min Wang, Yulern LinMost road surfaces in Taiwan are paved with asphalt concrete but the phenomena of rutting, cracking and stripping of the pavement are frequently occurring due to the effects of traffic flow, thermal variation and water erosion caused by rain. In this study, a series of experiments were performed to examine the effectiveness of anti-stripping fillers, which include; rock flour, rock … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 6,913 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluation of the Cytisus Triflorus (Lam.) Polyphenols Cicatrizing Activity on Experimental Thermal Burns in New Zealand RabbitsSihem Khadri, Nafissa Boutefnouchet, Youcef Hadef, Zouhir DjerrouThe present study aimed to evaluate the healing properties of the medicinal plant Cytisus triflorus widely used in the traditional treatment of wound healing. The principle of study is the application of the polyphenol extract of this plant prepared with vaseline in the form of a dermal ointment on thermal burns of second deep degree (circular of 379.94 mm2 in … …OnLine Journal of Biological Sciences, Vol. 18, Issue 3 · 12 May 2018 · 7,526 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLeafsnapNet: An Experimentally Evolved Deep Learning Model for Recognition of Plant Species based on Leafsnap Image DatasetEmmanuel Adetiba et al.Plants are very important living organisms on earth because humans and animals depend on them for nutrition, oxygen, medicine and balance in the ecosystem. Therefore, plant species recognition is critical to the improvement of agricultural productivity, mitigation of climate change and the discovery of new medicinal plants. However, species recognition has remained a difficult task even for trained botanists, because … …Journal of Computer Science, Vol. 17, Issue 3 · 1 Apr 2021 · 7,961 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleImpact of the Edges of a Backside Diffusive Reflector on the External Quantum Efficiency of Luminescent Solar Concentrators: Experimental and Computational ApproachMauro Pravettoni, Cristina S. Polo Lòpez, Robert P. KennyLuminescent Solar Concentrators (LSCs) have been proposed in the 1970s as cheap planar concentrators for residential applications and nowadays represent a novel idea with excellent perspectives for building integration photovoltaics. The interest in LSCs has increased in the last years, due to improved stability of luminescent dyes, the introduction of quantum dots and nanorods and the overall reported increase in … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 18 Jan 2016 · 8,368 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExperimental Evaluation of the Raking Energy in Damping System of Steel Stud Partition WallsSalah Amer, Sameer Hamoush, Taher M. Abu-LebdehNonstructural partition walls are usually specified based on the best practice without any structural design calculations. However, given the likely severe earthquake damage to nonstructural components and the substantial cost of repair to such components, it is imperative that we develop an understanding of the seismic response of the nonstructural partition walls when subjected to earthquake loading conditions. The main … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 6 Nov 2015 · 7,644 accessesView PDFCite
