An Exploratory study on default mode network's time course analysis
Akın, Burak; Gökçay, Didem; Department of Biomedical Engineering (2012)
At resting state, some parts of the human brain is more active than the other areas. Furthermore, the resting state activity in these areas exhibit a sudden decrease when the same areas are recruited in a task. Default mode network (DMN) is one of the resting state networks in the human brain, revealed through functional magnetic resonance (fMR) data acquisition while the subject is in an idle state. The aim of this study is to examine time-course properties of resting state default-mode network by using in...

Efficient synthesis of 1-alkoxycarbonyl-methyl-2-alkylpyrroles from dichloro- and methoxychloropropylalkyl ketones
Gadzhili, RA; Nadzhafova, RA; Sesenoglu, O (2002-01-01)
The condensation reaction of 2,3-dichloropropyl- and 2-methoxy-3-chloropropyl alkyl ketones with alkyl 2-aminoacetate salts leads to 1-alkoxy-carbonylmethyl-2-alkylpyrroles. These compounds, with various bases, gave 1-carbamoylmethyl-, 1-dialkylaminocarbonylmethyl-, 1-carbazoyl methyl-2-alkylpyrroles and potassium salt of 2-alkyl-pyrrolyl-1-acetic acid.
Analysis of koch fractal antennas
İrgin, Ümit; Birand, Mehmet Tuncay; Department of Electrical and Electronics Engineering (2009)
Fractal is a recursively-generated object describing a family of complex shapes that possess an inherent self-similarity in their geometrical structure. When used in antenna engineering, fractal geometries provide multi-band characteristics and lowering resonance frequencies by enhancing the space filling property. Moreover, utilizing fractal arrays, controlling side lobe-levels and radiation patterns can be realized. In this thesis, the performance of Koch curve as antenna is investigated. Since fractals a...
