A numerical method for frequency determination in the astable cellular neural networks with opposite-sign templates
(2006)In this study, a numerical method is proposed to determine the oscillation frequencies in the astable cellular neural networks with opposite-sign templates [1]. This method depends on the training of a multilayer perceptron ... -
Optical Spatial Modulation OFDM System Design [Optik Uzaysal Modülasyonlu OFDM Sistem Tasarımı]
(Institute of Electrical and Electronics Engineers Inc., 2016)In this paper a new optical orthogonal frequency division multiplexing (OFDM) method is proposed for multiple-input multiple-output (MIMO) visible light communications (VLC) systems. In the new scheme non-DC biased optical ... -
Optimization of graph affinity matrix with heuristic methods in dimensionality reduction of hypespectral images
(Institute of Electrical and Electronics Engineers Inc., 2019)Hyperspectral images include hundreds of spectral bands, adjacent ones of which are often highly correlated and noisy, leading to a decrease in classification performance as well as a high increase in computational time. ... -
Outage Probability of a Cooperative Maximum Ratio Transmission
(IEEE, 2014)In this paper we present a cooperative communication system employing maximum ratio transmission technique and its outage probability performance over Rayleigh fading channels. Since maximum ratio transmission can achieve ... -
Perception or Discourse? Security Threats in Copenhagen School and Neoclassical Realism
(2011)This article compares the perceptive approach of neoclassical realist security understanding with the discursive constructivist methodology of the Copenhagen School in analyzing the emergence of security threats. It departs ... -
Performance of SCMA Systems in Fast-Fading Channels
(Institute of Electrical and Electronics Engineers Inc., 2022)In order to satisfy the need for high data rate and high number of users, new generation communication techniques are developed. One of the techniques that may be used in future generation communication networks is Sparse ... -
Performance of stack equalizer over frequency selective fading channels [Frekansa ba?lı sönümlemeli kanallarda yi?it denkleştiricinin başarımı]
(2008)In this paper the performance of the low complexity modified stack equalizer over frequency-selective fading channels is inspected. With the help of simulation results it is illustrated that by sacrificing the computational ... -
Primary user detection in IEEE 802.15.4a based wireless sensor networks
(2013)Ultra wideband impulse radio (UWB-IR) technology has been defined in the IEEE 802.15.4a standard for location and ranging applications. In this paper, UWB-IR sensors are considered in wireless sensor networks (WSNs) with ... -
Programmed cell death in heart failure: Review [Programlı hücre ölümünün kalp yetersizli?indeki yeri]
(2005)The molecular and biochemical mechanisms of programmed cell death also known as apoptosis have not yet to be fully elucidated. Apoptosis is characterized by active intracellular communication loss of cellular attachment ... -
Real time detection and classification of age range smart signs at TV broadcast
(2011)In this paper, real time detection and classification of the "Smart Signs", which appear at the beginning and after the commercial breaks of the programs at national TV channels, that indicates the appropriate viewer ages ... -
Recycling of marine dredged materials coal fly ash and waste foundry sand as lightweight aggregates
(Gazi Univ Fac Engineering Architecture, 2019)Nowadays sustainable environmental management of high quantities of marine dredged material (DM) together with other industrial wastes is a common problem across Turkey. The beneficial use/recovery of DM and wastes in the ... -
Representing Earthquake Accelerogram Records for CNN Utilization
(IEEE, 2020)In this study, a spectrogram based false color representation of earthquake accelergrams is proposed and its usability for both human investigation and its application in convolutional networks are discussed. By using more ... -
Revisiting the mainstream approaches of the theories of international relations
(International Relations Council of Turkey, 2015)The view that we have reached the end of the “grand debates” in International Relations (IR) is widespread among the majority of IR scholars. Today, we observe that the references to the great theoretical debates in the ... -
RGB color based occupancy rate detection of indoor spaces [RGB renk tabanlı kapalı mekanların doluluk oranının belirlenmesi]
(Institute of Electrical and Electronics Engineers Inc., 2018)In this study a system has been developed to detect the human density of indoor spaces such as libraries banks shopping malls. The RGB images used in this work was obtained from the real-life space. First and second order ... -
