A Network representation of households by health exclusion, poverty, and unemployment
(Elsevier Science BV, 2011)Social exclusion, emphasized in the European Social Agenda, presents an interesting case study on the discussion of universal vs. means-tested social policies. To understand the conditions under which universal policies ... -
Network synchronization: Spectral versus statistical properties
(Elsevier B.V., 2006-12)We consider synchronization of weighted networks, possibly with asymmetrical connections. Focusing on causal relations rather than the observed correlations, we show that the synchronizability of networks cannot be directly ... -
Neural network as a forecasting tool for financial decision-making
(Işık Üniversitesi, 2008-09-18)For the last decade, machine learning techniques have been applied to financial tasks such as portfolio management, risk assessment and stock market prediction. Among these techniques artificial neural network as a machine ... -
Neural network based face detection
(Işık Üniversitesi, 2010)One of the challenging problems in computer vision is face detection. The goal of face detection is to locate all regions that contain a face regardless of any three dimensional transformation and lighting condition. There ... -
Neural network modeling of convection heat transfer coefficient for the casson nanofluid
(Işık University Press, 2021)This paper presents applications of Artificial Neural Network (ANN) to develop a mathematical model of magnetohydrodynamic (MHD) flow and heat transfer in a Casson nanofluid. The model equations are solved numerically by ... -
Neural network steering control algorithm for autonomous ground vehicles having signal time delay
(SAGE Publications Ltd, 2024-03)An adaptive neural network–based steering control algorithm is proposed for yaw rate tracking of autonomous ground vehicles with in-vehicle signal time delay. The control system consists of two neural networks: the observer ... -
Neuroimaging findings related to panic disorder: a brief review
(Klinik Psikoloji Araştırmaları Derneği, 2022-12-26)Panic disorder (PD) is defined by recurrent unanticipated panic attacks and anxiety of losing control, which negatively affects the patients’ quality of life. Various neuroimaging techniques allow to assess brain structure ... -
Neuropsychiatric outcomes and caregiver distress in primary progressive aphasia
(Wiley, 2023-01)Background: In this study, we aimed to outline the neuropsychiatric consequences of primary progressive aphasia (PPA) and to understand how neuropsychiatric symptomatology affects distress in caregivers. Methods: The ... -
A new algorithm for high speed speech and audio coding
(IEEE, 2007)In this work, a new mathematical modeling approach is proposed for the representation of the speech and audio signals. This approach is based on the generation of the so called Predefined Signature Sequence (PSS) and ... -
A new algorithm for joint time and phase synchronization in OFDM systems
(IEEE, 2000)In this paper, a computationally efficient algorithm is presented for joint maximum likelihood (ML) timing and carrier phase synchronization of OFDM systems employing M-PSK modulation scheme with additive Gaussian noise, ... -
A new approach for named entity recognition
(IEEE, 2017)Many sentences create certain impressions on people. These impressions help the reader to have an insight about the sentence via some entities. In NLP, this process corresponds to Named Entity Recognition (NER). NLP ... -
A new approach to find an approximate solution of linear initial value problems with high degree of accuracy
(Işık University Press, 2022)This work investigates a new approach to find closed form solution to linear initial value problems (IVP). Classical Bernoulli polynomials have been used to derive a finite set of orthonormal polynomials and a finite ... -
A new approach to find approximate solutions of Burger’s and coupled Burger’s equations of fractional order
(Işık University Press, 2021)The paper presents a new technique called homotopy perturbation Sumudu transform Method (HPSTM), which is a combination of the Sumudu transform (ST) and homotopy perturbation method (HPM) for solving the fractional Burger’s ... -
New approach to the solutions of the pib equation
(Işık University Press, 2011-02-27)In this paper, based on the Exp-function method and mathematical derivation, we obtain several explicit and exact traveling wave solutions for the PIB equation. -

A new block Markov coding strategy for pairwise and collective cooperation in the three user MAC
(IEEE, 2013)For a three user cooperative multiple access channel (MAC), we propose a new block Markov superposition encoding strategy, which enables all three users to cooperate collectively as well as in pairs. We obtain the resulting ... -
New characterizations of spacelike curves on timelike surfaces through the link of specific frames
(Işık University Press, 2018)In this work, considering a regular spacelike curve on a smooth timelike surface in Minkowski 3-space, we investigate relations between the mentioned curve’s Darboux and Bishop frames on the timelike surface. Next we obtain ... -
