Climatic conditions affect the performance of photovoltaic panels. In this study, the effect of ambient air temperature and relative humidity on the performance parameters of two types of silicon photovoltaic solar panels, including mono-crystalline silicon (mc-Si) and polycrystalline silicon (pc-Si), were studied in the laboratory scale. The experiments were carried out by the performance test...
Packaging products as services can create financial opportunities for suppliers and can create the economies of scale which help environmentally preferable products (EPP) achieve their maximum effectiveness. For suppliers, offering product service systems (PSS) broadens their market to reach customers who are only interested in purchasing a financed or valued-added version of the product. Envir...
Over the past few months, NASA has been in the news numerous times both for the exciting discoveries of the pair of Mars Rovers as well as the country’s “Vision for Space Exploration.” This vision focuses on the joint human and robotic exploration of the solar system starting with a return to the moon and then the human exploration of Mars. In addition, the vision includes a continued array of ...
*Correspondence: Valéry Masson, Météo-France/CNRS, Centre National de Recherches Météorologiques/Groupe d’étude de l’atmosphère Météorologique, 42 av Coriolis, 31057 Toulouse, France e-mail: [email protected] The production of solar energy in cities is clearly a way to diminish our dependency to fossil fuels, and is a good way to mitigate global warming by lowering the emission of greenhou...
A panel of biomarkers may improve predictive performance over individual markers. Although many biomarker panels have been described for ovarian cancer, few studies used prediagnostic samples to assess the potential of the panels for early detection.We conducted amultisite systematic evaluation of biomarker panels using prediagnostic serum samples from the Prostate, Lung, Colorectal, andOvarian...
The measures needed for the protection of the Earth’s ozone layer are decided regularly by the Parties to the Montreal Protocol, now consisting of 184 countries. The Parties are advised on knowledge relevant to this task by three panels of experts: the Scientific, Environmental Effects, and Technology and Economic Assessment Panels. These panels produce an assessment every four years; the lates...
A combination Sceptor Breakpoint/ID panel (Johnston Laboratories, Inc., Towson, Md.), which determines interpretive susceptibility results (susceptible, moderately susceptible, and resistant) using two to three selected concentrations of antimicrobial agents, was tested in comparison with full-range Sceptor microdilution MIC panels. The interand intralaboratory interpretive reproducibilities fo...
Large solar panels were constructed from polymer solar cell modules prepared using full roll-to-roll (R2R) manufacture based on the previously published ProcessOne. The individual flexible polymer solar modules comprising multiple serially connected single cell stripes were joined electrically and laminated between a 4 mm tempered glass window and black Tetlar foil using two sheets of 0.5 mm th...
In this paper, we present the virtual prototyping of a solar array with a grid-tie implemented as a distributed inverter and controlled using distributed algorithms. Due to the distributed control and inherent redundancy in the array composed of many panels and inverter modules, the virtual prototype exhibits fault-tolerance capabilities. The distributed identifier algorithm allows the system t...
