Yayın An analysis of stability of a class of neutral-type neural networks with discrete time delays(Hindawi Publishing Corporation, 2013) Orman, Zeynep; Arik, SabriThe problem of existence, uniqueness, and global asymptotic stability is considered for the class of neutral-type neural network model with discrete time delays. By employing a suitable Lyapunov functional and using the homeomorphism mapping theorem, we derive some new delay-independent sufficient conditions for the existence, uniqueness, and global asymptotic stability of the equilibrium point for this class of neutral-type systems. The obtained conditions basically establish some norm and matrix inequalities involving the network parameters of the neural system. The main advantage of the proposed results is that they can be expressed in terms of network parameters only. Some comparative examples are also given to compare our results with the previous corresponding results and demonstrate the effectiveness of the results presented.Yayın Behavior of quantum fisher information of bell pairs under decoherence channels(Polish Acad Sciences Inst Physics, 2014-02) Özaydın, Fatih; Altıntaş, Azmi Ali; Buğu, Sinan; Yeşilyurt, CanQuantum Fisher information has recently been an essential tool for analyzing the phase sensitivity of the quantum states in various quantum tasks, requiring high precision, such as quantum clock synchronization, positioning and many applications which include quantum interferometers. Due to the interactions with the environment, all quantum systems are subject to various decoherence effects. Therefore the research on quantum Fisher information under decoherence has been recently attracting more attention. In this work, analyzing the quantum Fisher information, we study the phase sensitivity of bipartite quantum correlations, in particular four Bell pairs amplitude damping channels. For a specific Bell state we arrive at similar results of Greenberger-Horne-Zeilinger (GHZ) states (as expected). For the other three Bell states, we present our results which point the interesting behavior of quantum Fisher information with respect to the decoherence rate. We also find the regions where the quantum Fisher information exhibits discontinuities.Yayın Analysis of Nonlinear Dynamics of Neural Networks(Hindawi Publishing Corporation, 2013) Arik, Sabri; Park, Juhyun; Huang, Tingwen; Oliveira, José J[No abstract available]Yayın An essential approach to the architecture of diatomic molecules: 1.Basic theory(Optical Soc Amer, 2004-11) Yarman, Nuh TolgaWe consider the quantum-mechanical description of a diatomic molecule of electronic mass m(0e), internuclear distance R-0, and total electronic energy E-0e. We apply to it the Born-Oppenheimer approximation, together with the relation E(0e)m(0e)R(0)(2) similar to h(2) (which we established previously), written for the electronic description (with fixed nuclei). Our approach yields an essential relationship for T-0,T- the classical vibration period, at the total electronic energy E-0e; i.e., T-0 = [4pi(2)/(rootn(1)n(2)h)] rootgM(0)m(e) R-0(2). Here, At,0 is the reduced mass of the nuclei; m(e) is the mass of the electron; g is a dimensionless and relativistically invariant coefficient. roughly around unity (this quantity is associated with the particular electronic structure under consideration; thus, it remains practically the same for bonds bearing similar electronic configurations); and n(1) and n(2) are the principal quantum numbers of electrons making up the bond(s) of the diatomic molecule in hand: because of quantum defects, they are not integer numbers. The above relationship holds generally, although the quantum numbers n(1) and n(2) need to be refined. This task is undertaken in our next article, yielding a whole new systematization regarding all diatomic molecules.Yayın An essential approach to the architecture of diatomic molecules: 2. how are size, vibrational period of time, and mass interrelated?(Optical Soc Amer, 2004-11) Yarman, Nuh TolgaIn our previous article, we arrived at an essential relationship for T the classical vibrational period of a given diatomic molecule, at the total electronic energy E-, i.e., T = [4pi(2)/(rootn(1)n(2)h)] rootgM(0)m(e) R-2, where M-0 to is the reduced mass of the nuclei; m(3) is the mass of the electron; R is the internuclear distance: g is a dimensionless and relativistically invariant coefficient, roughly around unity; and n(1) and n(2) are the principal quantum numbers of electrons making up the bond(s) of the diatomic molecule, which, because of quantum defects. are not integer numbers. The above relationship holds generally. It essentially yields T similar to R 2 for the classical vibrational period versus the square of the internuclear distance in different electronic states of a given molecule. which happens to be an approximate relationship known since 1925 but not understood until now. For similarly configured electronic states, we determine n(1)n(2) to be R/R-0, where R is the internuclear distance in the given electronic state and R-0 is the internuclear distance in the ground state. Furthermore. from the analysis of H-2 spectroscopic data, we found out that the ambiguous states of this molecule are configured like alkali hydrides and Li-2. This suggests that, quantum mechanically, on the basis of an equivalent H-2 excited state. we can describe well, for example, the ground state of Li-2. On the basis of this interesting finding, herein we propose to associate the quantum numbers n(1) and n2 With the bond electrons of the ground state of any diatomic molecule belonging to a given chemical family in reference to the ground state of a diatomic molecule still belonging to this family but bearing, say, the lowest classical vibrational period, since g, depending only on the electronic configuration. will stay nearly constant throughout. This allows us to draw up a complete systematization of diatomic molecules given that g (appearing to be dependent purely on the electronic structure of the molecule) stays constant for chemically alike molecules and n(1)n(2) can be identified to be R-0/R-00 for diatomic molecules whose bonds are electronically configured in the same way, R-00 then being the internuclear distance of the ground state of the molecule chosen as the reference molecule within the chemical fan-Lily under consideration. Our approach discloses the simple architecture of diatomic molecules, otherwise hidden behind a much too cumbersome quantum-mechanical description. This architecture, telling how the vibrational period of Lime. size. and mass are determined, is Lorentz-invariant and can be considered as the mechanism of the behavior of the quantities in question in interrelation with each other when the molecule is brought into uniform translational motion or transplanted into a gravitational field or, in fact, any field with which it can interact.Yayın Optimisation of pedestrian detection system using FPGA-CPU hybrid implementation for vehicle industry(Inderscience Enterprises Ltd., 2019) Özcan, Ahmet Remzi; Tavşanoǧlu, Ahmet VedatImproved image processing and developing technologies are rapidly expanding the application areas of image processing systems. In recent years, pedestrian detection systems have become one of the major safety technologies used in the automotive industry. This paper presents an optimised real-time pedestrian detection system using an FPGA-CPU based hybrid design. The histograms of oriented gradients (HOG) algorithm, which is extensively used for feature extraction in pedestrian detection applications, was implemented on a low-end FPGA. In the study, the original HOG descriptors are designed in low complexity without sacrificing performance. The obtained features were classified on a low-power single board computer with support vector machine (SVM). Tests with the INRIA pedestrian database show that the proposed model has high potential for use as a real-time low-cost pedestrian detection system in practice.Yayın Paraoxonase (PON1) L55M and Q192R polymorphisms in major depression and bipolar affective disorder(Univ Sao Paulo, 2017-05/06) Yıldız, Mesut; Çam Çelikel, Feryal; Ateş, Ömer; Erdoğan Taycan, Serap; Benli, İsmail; Demir, OsmanBackground: Oxidative and nitrosative stress pathways, along with immune-inflammatory response, might play an important role in the pathogenic mechanisms underlying major depression and bipolar disorder. Objective: The aim of the present study is to investigate paraoxonase 1 polymorphisms and its correlations with disease parameters in patients with major depression and bipolar affective disorder. Methods: PON1 L55M and Q192R single nucleotide polymorphisms were analyzed in a group consisted of 100 patients with major depression, and 100 patients with bipolar affective disorder and 96 healthy controls. Polymorphisms were analyzed by using polymerase chain reaction. Results: Our findings reported no association between Q192R and L55M polymorphisms of PON1 and major depression and bipolar disorder. Additionally, there was no association between the PON1 genotypes and disease variables in both depressed and bipolar patients. Discussion: Evaluating the different stages of patients with affective disorders and and investigating the connection between PON1 polymorphisms and treatment outcomes will help us to clarify the relationship between PON1 and mood disorders.Yayın An investigation of the certain class of multivalent harmonic mappings(Eudoxus Press, 2016-03) Özkan Uçar, Hatice Esra; Polatoğlu, Yaşar; Aydoğan, Seher MelikeThe main purpose of the present paper is to investigate some properties of the certain class of sense-preserving p-valent harmonic mappings in the open unit disc D = {z is an element of C parallel to z vertical bar < 1}.Yayın Notes on harmonic functions for which the second dilatation is α - spiral(Eudoxus Press, 2015-06) Aydoğan, Seher MelikeIn this study, we consider, f = h + (g) over bar harmonic functions in the unit disc D.
