Realization of a cue based motor imagery brain computer interface with its potential application to a wheelchair
Akıncı, Berna; Gençer, Nevzat Güneri; Department of Electrical and Electronics Engineering (2010)
This thesis study focuses on the realization of an online cue based Motor Imagery (MI) Brain Computer Interface (BCI). For this purpose, some signal processing and classification methods are investigated. Specifically, several time-spatial-frequency methods, namely the Short Time Fourier Transform (STFT), Common Spatial Frequency Patterns (CSFP) and the Morlet Transform (MT) are implemented on a 2-class MI BCI system. Distinction Sensitive Learning Vector Quantization (DSLVQ) method is used as a feature sel...
Finite element investigation of mechanical interaction of dental implants with bone
Eser, Atılım; Tönük, Ergin; Department of Mechanical Engineering (2007)
During the last years, biomechaniccs, the understanding of the very complex mechanical behavior of living tissue, becomes a very important field of research of the wide bravch of mechanichs. Thia study is very important, for instance , to improve the design of implants, with the important social and economical impact. one of important challenges in implant design is to model the complex material behavior of the bone. Remodeling of the bone due to the lodaing is one of the essential behaviors of the bone whi...
Integrated biomimetic scaffolds for soft tissue engineering
Güven, Sinan; Hasırcı, Nesrin; Department of Biotechnology (2006)
Tissue engineering has the potential to create new tissue and organs from cultured cells for transplantation. Biodegradable and biocompatible scaffolds play a vital role in the transfer of the cultured cells to a new tissue. Various scaffolds for soft tissue engineering have been developed, however there is not any structure totally mimicking the natural extracellular matrix (ECM), ready to use. In this study biodegradable and biocompatible scaffolds were developed from natural polymers by tissue engineerin...
An empirical study on early warning systems for banking sector
Boyraz, Mustafa Fatih; Gaygısız Lajunen, Esma; Department of Economics (2012)
Early Warning Systems (EWSs) for banking sectors are used to measure occurrence risks of banking crises, generally observed with a rundown of bank deposits and widespread failures of financial institutions. In countries with a small number of banks, for example Turkey with 48 banks (BDDK, 2011), every bank may be considered to have a systematic importance since the failure of any individual bank may carry a potential threat to lead to a banking crisis. Taking into account this fact the present study focuses...
