Maximizing the performance of single and multijunction MA and lead-free perovskite solar cell Azadinia, M.; Ameri, Mohsen; Ghahrizjani, R.T.; Fathollahi, M. (2021-06-01) Finding a highly stable and appropriate perovskite solar cell with optimum design parameters is crucial for being included as the top cell in tandem structure, with Si as the bottom cell, to realize the power conversion efficiencies (PCEs) over the limits imposed by Shockley-Queisser theory. Here, we quantize the performance of methylammonium (MA) and lead (Pb)-free all-inorganic cesium tin-germanium triiodide (CsSnxG1-xI3) by combining CsSnI3 (Eg = 1.31 eV) and CsGeI3 (Eg = 1.63 eV) perovskites for standal...
Maximizing the energy potential of urban sludge treatment: An experimental study and a scenario-based energy analysis focusing on anaerobic digestion with ultrasound pretreatment and sludge combustion Çelebi, Emrehan Berkay; Aksoy, Ayşegül; Sanin, Faika Dilek (2021-04-01) With stricter regulations and concerns over sustainability, combustion can be a beneficial handling method as dried sludge can be used as an energy source. Anaerobic digestion of sludge also provides energy in the form of biogas without the need for sludge drying. Yet, anaerobic digestion reduces the calorific value (CV) of sludge. In this study, the effect of anaerobic digestion (with or without ultrasound pretreatment) on the fuel properties of sludge were examined through laboratory experiments. Addi-tio...
Optimizing the Number of Fog Nodes for Cloud-Fog-Thing Networks Balevi, Eren; Gitlin, Richard D. (2018-01-01) Fog networking has recently received considerable attention from a theoretical perspective, but in order for such networks to be practical several open areas need to be addressed. This paper determines the optimum number of nodes that should be upgraded to fog nodes with additional computing capabilities in order to maximize the average data rate and minimize the transmission delay. The optimization is performed for a given set of wireless channel conditions and a fixed total number of network nodes. It wil...
Forecasting total electron content maps by neural network technique Tulunay, Ersin; Senalp, Erdem Turker; Radicella, Sandro Maria; Tulunay, Yurdanur (American Geophysical Union (AGU), 2006-08-17) [ 1] Near-Earth space processes are highly nonlinear. Since the 1990s, a small group at the Middle East Technical University in Ankara has been working on a data-driven generic model of such processes, that is, forecasting and nowcasting of a near-Earth space parameter of interest. The model developed is called the Middle East Technical University Neural Network (METU-NN) model. The METU-NN is a data-driven neural network model of one hidden layer and several neurons. In order to understand more about the c...
