Investigation of digital elevation model uncertainty in GIS-based solar radiation models using Markov Chain Monte Carlo simulation
Ismaila, Abdur-Rahman Belel; Düzgün, H. Şebnem; Ediger, Volkan; Department of Geodetic and Geographical Information Technologies (2013)
In this study, a Markov chain Monte Carlo (MCMC) simulation approach that incorporates digital elevation model's (DEM) spatial autocorrelation is developed with the aim of assessing the impact of DEM uncertainty in GIS-based solar radiation models. The method utilized the error probability distribution function (pdf) of Shuttle Radar Topography Mission (SRTM) DEM, and variogram model parameters of the study area's SRTM DEM as a priori information for the formulation of Metropolis-Hasting algorithm. Statisti...
Investigation of electromigration induced hillock and edge void dynamics on the interconnect surface by computer simulation
Çelik, Aytaç; Oğurtanı, Tarık Ö.; Department of Metallurgical and Materials Engineering (2004)
The Electromigration-induced failure of metallic interconnects is a complicated process, which involves flux divergence, vacancy and atom accumulation with or without compositional variations, void and hillocks nucleation, growth and shape changes. Hillocks and surface void dynamics in connection with the critical morphological evaluation have been investigated in order to understand the conditions under which premature failure of metallic thin interconnects occur. In this thesis, an interconnect is idealiz...
Investigation of Simulated Ground Penetrating Radar Data for Buried Objects Using Quadratic Time-Frequency Transformations
DOĞAN, MESUT; Sayan, Gönül (2017-07-14)
Sub-surface sensing is a challenging area of research that highly benefits from the use of ultra-wideband ground penetrating radar (GPR) technology. Detection and classification of buried objects with reduced false alarm rates is still open to improvements. Use of joint temporal and spectral target features obtained from electromagnetic GPR signals using time-frequency representation (TFR) methods is highly promising because TFRs provide detailed information about the energy distribution of GPR signals over...
Investigation of the structural properties of silicene nanoribbons by molecular dynamics simulations
İnce, Alper; Erkoç, Şakir; Aydınol, Mehmet Kadri; Department of Micro and Nanotechnology (2012)
With the emergence of nanotechnology, mankind has obtained the capability to manipulate materials at nanoscale and this led to the invention of a new group of novel materials like carbon nanotubes, graphene and quantum nanodots. Silicene nanoribbons (SiNRs) are one of the newest members of this nanomaterial family which has been synthesized very recently by deposition on silver substrates. A SiNR sheet is made up of a layer of two dimensional honeycomb structure solely composed of silicon atoms. In this the...
Investigation of electromigration and stress induced surface dynamics on the interconnect by computer simulation
Çelik, Aytaç; Oğurtanı, Tarık Ö.; Aydınol, Mehmet Kadri; Department of Metallurgical and Materials Engineering (2011)
Purpose of this work is to provide a comprehensive picture of thin film (interconnect) and solid droplet surface evolution under the several external applied forces with anisotropic physical properties so that one can eventually be able to predict main reasons and conditions under which stability of surface is defined. A systematic study based on the self-consistent dynamical simulations is presented for the spontaneous surface evolution of an thin film and isolated thin solid droplet on a rigid substrate, ...
