Silicon nanostructures for electro-optical and photovoltaic applications
Kulakcı, Mustafa; Turan, Raşit; Department of Physics (2012)
Recently extensive efforts have been spent in order to achieve all silicon based photonic devices exploiting the efficient light emission from nanostructured silicon systems. In this thesis, silicon based nanostructures have been investigated for electro-optical and photovoltaic applications. The thesis focused on three application areas of silicon nanostructures: Light emitting diode (LED), light modulation using quantum confined Stark effect (QCSE) and photovoltaic applications. In the context of LED appl...
Uncertainty quantification of transient unsaturated seepage through embankment dams
Çalamak, Melih; Yanmaz, Ali Melih (American Society of Civil Engineers (ASCE), 2017-06-01)
Sensitivity analysis is conducted to investigate the effects of uncertainty in hydraulic conductivity and van Genuchten parameters on transient seepage. To this end, a random number generator is used to generate random values from probability distributions of each parameter. The generator is coupled with finite-element software that handles seepage analysis in porous media. The Monte Carlo simulation approach is adopted for stochastic seepage analyses. The suggested method is applied on a homogeneous dam ma...

The knowledge of the statistical parameters of the variance, sigma-2, and the correlation scale, lambda, characterizing the spatial structures of the log of the saturated hydraulic conductivity, lnK(s), pore size distribution parameter alpha, and the specific water capacity, C, is required in stochastic modeling in order to understand the overall response of large-scale heterogenous unsaturated flow systems. These parameters are estimated assuming second-order stationarity and an exponential semivariogram ...
Nonlinear dynamics of the Black Sea ecosystem and its response to anthropogenic and climate variations
Akoğlu, Ekin; Salihoğlu, Barış; Department of Marine Biology and Fisheries (2013)
The main objective of this research is to i) provide a quantitative understanding of the changes in the Black Sea ecosystem between 1960 – 1999, ii) to identify its food web dynamics including the infamous anchovy – Mnemiopsis shift in 1989, and iii) utilizing this understanding to explore future progressions of the Black Sea ecosystem under predicted future physical and biogeochemical changes. For this purpose, three different but complementary approaches were used all of which were detailed under three di...
