PROTECTION OF NATURAL CATCHMENT AREAS SUPPLYING WATER TO ISTANBUL AND MONITORING ILLEGAL CONSTRUCTION WITH PERIODICALLY COLLECTED IKONOS IMAGERY
Satellite IKONOS Change Detection Illegal Construction Catchment Area

Being one of the fastest growing cities in the world in terms of population, Istanbul suffers significantly from illegal construction
which is very difficult even to monitor with field survey method...
Chirality control by electric field in periodically poled MgO-doped lithium niobate
Chirality control electric field periodically poled MgO-doped lithium niobate Optics
2012/4/19
We study the chirality of periodically poled MgO-doped lithium niobate (MgO:PPLN) by electro-optic (EO) effect. It shows that optical propagation is reciprocal in MgO:PPLN when quasi-phase-matching (Q...
Periodically fighting shake, rattle and roll
Dynamical Systems Periodically rattle and roll
2011/8/31
Abstract: How easy is it to suppress shake, rattle and roll in a long bridge or a skyscraper? Most practical structures are designed so that long wave resonance vibrations can be avoided. However, the...

2015/5/20
We experimentally demonstrate 7dB improvement in Brillouin suppression in a photonic crystal fiber by periodically varying the size of the air-hole-structure by only 7% amplitude while keeping a low a...
Asymptotic distributions and subsampling in spectral analysis for almost periodically correlated time series
α-mixing properties almost periodically correlated time series consistency spectral analysis subsampling
2011/3/21
The aim of this article is to establish asymptotic distributions and consistency of subsampling for spectral density and for magnitude of coherence for non-stationary, almost periodically correlated t...
Effective Willis constitutive equations for periodically stratified anisotropic elastic media
Effective Willis constitutive equations periodically stratified anisotropic elastic media
2011/3/4
A method to derive homogeneous effective constitutive equations for periodically layered
elastic media is proposed. The crucial and novel idea underlying the procedure is that the
coefficients of th...
Bistability and resonance in the periodically stimulated Hodgkin-Huxley model with noise
Bistability Hodgkin-Huxley model
2011/1/6
We describe general characteristics of the Hodgkin-Huxley neuron's response to a periodic train of short current pulses with Gaussian noise. The deterministic neuron is bistable for antiresonant frequ...
