摘要: We describe a very simple experiment that allows college students in introductory physics courses to plot the I-V characteristics of a solar cell, and hence measure important photovoltaic parameters, such as the fill factor and light conversion efficiency. ...
heavily on the use of theoretical models to compute viscosity. Others have done similar experiments using different instruments. Rotational and vibrating wire viscometers have been used, which allows for a wider range of parameters in the experiments. One such parameter is the shear rate. The shear...
In general, the chapter provides an overview of research that addressed PMTC of prospective teachers of mathematics [PTs] through a systematic review and synthesis of relevant published empirical studies for the period 2000 to 2020. It begins with an overview of the scope of the literature review,...
During the experiment, the nozzle of the corresponding cooling system was orthogonal to the position of the work-piece. A plant-based cutting oil was used in both the MQL mode and the flood cooling mode. This is a plant-based synthetic oil that can be biologically explained. It's main ...
Based on laboratory experiment, this study investigated the deformation, fracture, and instability characteristics of a coal-rock parting compound structure in a bifurcation area—including deformation, crack development, and energy release—and the precursor information of failure and instability was also ...
Variation of rolling element bearing friction torque The statistical characteristics of the rolling element bearing friction torque are analyzed to find its evolvement law, via the experiment on the friction ...

Similarly, for each experiment, the combustion chamber underwent the same procedure. It was initially evacuated to an absolute pressure of <10 mbar and then filled with dry compressed air up to 7 bar absolute pressure. This vacuum and purge process was also repeated twice to effectively remove ...
Ocean dynamics are characterized by a very broad range of scales of motion. This corresponds to a large number of multiscale dynamical features which are generally present in the different ocean sub-basins: from large scale gyres and boundary currents to mesoscale eddies, down to the submesoscale...
of experiment setup or design choices6,7,8. A recent study by curators of the BioModels database showed that only 51% of 455 published models were directly reproducible8. In an extreme case, Topalidou et al.9report requiring three months to reproduce a neuroscientific model of the basal ...
Although oxide-based resistive switching memory (OxRAM) is one of the strong next-generation high capacity memory candidates, it has the critical disadvantage that deviations of resistance levels is too severe to be adopted as a high capacity memory device. More specifically, it is known that the...
