A new memristor-based low-pass filter topology and its small-signal solution using MacLaurin series

Yener, Şuayb Çağrı; Resat Mutlu; H. Hakan Kuntman (NATL INST OPTOELECTRONICS, 2015)

In this work, a new memristor-based low-pass filter topology is suggested. Memristor-based filters are nonlinear circuits and many of them cannot be solved analytically. To find an approximate analytical solution of the ...
A new seven-term chaotic attractor and its hyperchaos

Can, Engin; Uyaroğlu, Yılmaz (NATL INST OPTOELECTRONICS, 2015)

In this paper a new chaotic system reported. Some basic dynamical properties of the new attractor are demonstrated in terms of equilibria, Jacobian matrices, Lyapunov exponents, chaotic waveform in time domain, continuous ...
A novel chaotic attractor and its weak signal detection application

A. Gokyildirim; Uyaroğlu, Yılmaz; Pehlivan, İhsan (ELSEVIER GMBH, 2016)

In this paper, we present a new sinusoidal chaotic attractor and its weak signal detection application. This new system has a simple structure, parametric variety and high applicability. Its dynamic characteristics are ...
A SURVEY AND MEASUREMENT BASED STUDY ON DIMMABLE LIGHTING TO EVALUATE VISUAL PERFORMANCE AND LIGHTING ENERGY SAVINGS

Erginöz, Banu; Yavuz, Cenk (ZNACK PUBLISHING HOUSE, 2017)

Energy saving has been one of the most important issues discussed in lighting systems lately. One of the most common applications to provide energy savings in lighting are scenarios involving the utilization of dimmable ...
A system theoretic approach to array processing

Demirkol, Aşkın; Demir, Zafer; Erol, Emre (NATL INST OPTOELECTRONICS, 2015)

In this paper, utilizing system theoretic concepts a sound, rigorous theory of array processing is established which leads to several new results. MUSIC, MIN-NORM, ESPRIT, and PISARENKO used for both spatial and temporal ...
A unifying approach to track-to-track correlation for multisensor fusion for multiple targets

Demirkol, Aşkın; Demir, Zafer; Emre, Erol (NATL INST OPTOELECTRONICS, 2015)

In this paper, a global modeling approach was proposed for multi sensor fusion problems. Once the global model was investigated considering the data association and fusion, it is adapted to track to track correlation problem ...
Adaptive neural network based stabilization and trajectory tracking control of discrete-time chaotic systems

Kursad Gokce; Uyaroğlu, Yılmaz (NATL INST OPTOELECTRONICS, 2015)

This paper investigates the stability and tracking performance of discrete-time chaotic systems in the presence of external disturbance and noise. For this purpose, a neural network control scheme is developed on the basis ...
An ambiguity function aided target density function for radar imaging

R. F. Cinar; Demirkol, Aşkın; Demir, Zafer (NATL INST OPTOELECTRONICS, 2015)

This paper investigates a new approach to target density functions for active sensor imaging. The data obtained from a phased array radar system is processed by the newly developed technique. In order to reconstruct the ...
Buried underground archaeological structures investigation with electrical method: diyarbakir Ulu Mosque (Turkey)

Karavul, Can; Nihan Arig; T. Fikret Kurnaz; Demirkol, Aşkın (NATL INST OPTOELECTRONICS, 2015)

The study area used as a temple during the pre-Christianity term, Mar Thoma Church after the adoption of Christianity and currently used as The Ulu Mosque. The most important feature of this mosque which has hosted many ...
