Particle dynamics in the KdV approximation
(Elsevier Science BV, 2012-12)The KdV equation arises in the framework of the Boussinesq scaling as a model equation for waves at the surface of an inviscid fluid. Encoded in the KdV model are relations that may be used to reconstruct the velocity field ... -
Particle size and shell thickness dependence of the light intensity enhancement in the cap layers of Ag, Au, Al and SiO2@TiO2 core-shell nanostructures
(Wiley-V C H Verlag GMBH, 2018-03-22)We present a systematic study of the light intensity enhancement in the shell layers of half burrried Ag, Au, Al and SiO2 spherical nanoparticles capped with TiO2. We calculated the light intensity profiles near these ... -
Path loss and RMS delay spread model for VLC-based patient health monitoring system
(Institute of Electrical and Electronics Engineers Inc., 2022-05-13)Visible Light Communication (VLC) emerges as a supplementary technology to ubiquitous Radio Frequency (RF) since VLC meets the very high data rate, very high reliability, and ultra-low latency requirements driven by the ... -
A path loss model for link budget analysis of indoor visible light communications
(Istanbul Univ-Cerrahpasa, 2021-05)In the context of beyond 5G indoor communication systems, visible light communications (VLC) has emerged as a viable supplement for existing radio frequency based systems and as an enabler for high data rate communications. ... -
A path loss model for vehicle-to-vehicle visible light communications
(Institute of Electrical and Electronics Engineers Inc., 2019-07)The increasing adoption of LEDs in exterior automotive lighting makes visible light communication (VLC) a natural solution for vehicular networking. In this paper, we consider a vehicle-to-vehicle link and propose a path ... -
Pedestrian crossing behavior at midblock crosswalks
(Elsevier Ltd, 2019-12)Introduction: This study investigated the pedestrian crossing behavior at midblock crosswalks, in Istanbul. Method: Data were compiled from field studies at four selected crosswalks that were on one-way streets. Three of ... -
Pediatrik astımda kaygı, depresyon, somatizasyon veyaşam kalitesi ile serum IgE düzeyi ilişkisi
(Psikiyatride Güncel Yaklaşımlar, 2019-12-28)Bu çalışmanın amacı çocuklarda astım şiddeti il”e depresyon, açık kaygı, yaşam kalitesi, somatizasyon gibi değişkenleri ve astımda bağışıklık sistemi belirleyicilerinden olan IgE düzeyi arasındaki olası ilişkiyi analiz ... -
Peer-mentoring among female biomedical engineering students can be extended to other engineering disciplines
(2004-06)Mentoring is significant personal and professional assistance given by a more experienced person to a less experienced person during a time of transition. Transitions from high school to university, from university to ... -
People respond with different moral emotions to violations in different relational models: a cross-cultural comparison
(American Psychological Association, 2021-06)Consonant with a functional view of moral emotions, we argue that morality is best analyzed within relationships rather than in individuals, and use Fiske's (1992) theory of relational models (RMs: communal sharing [CS], ... -
Perceived self-society moral discrepancies predict depression but not anxiety
(Blackwell Publishing Ltd, 2015-12)Discrepancies between one's own beliefs, standards and practices and the standards expected by others are associated with increased vulnerability to depression and anxiety. Perhaps the most important personal standard is ... -
Percolation approach to film formation from surfactant-free polystyrene particles
(Taylor & Francis, 2005-09)In this study, a film formation process from surfactant-free polystyrene (PS) latex particles is reported. Steady state fluorescence (SSF) and photon transmission (UVV) techniques were used to study the evolution of film ... -
Performance analysis of an aggregation and disaggregation solution procedure to obtain a maintenance plan for a partially observable multi-component system
(Elsevier Sci Ltd, 2017-11)We analyze the performance of an aggregation and disaggregation procedure in giving the optimal maintenance decisions for a multi-component system under partial observations in a finite horizon. The components deteriorate ... -
Performance analysis of Turkish banking sector: CAMELS implementation
(PressAcademia, 2020-07-30)Purpose- These effects lead to many crises in the country, especially the economic crisis, and may result in serious chaos environments. In order not to experience these situations, the banking sector must be under audit ... -
Performance of airlines: topsis analysis
(PressAcademia, 2022-07-30)Purpose- Airline industry is very important for modern society and has a crucial role for globalization and business development by connecting regions, promoting global trade and tourism and hence enabling economic and ... -
Perspectives on Turkey’s 2017 presidential referendum
(Rubin Center for Research in International Affairs, 2017-03)Until the 1980s, Turkey’s long-standing parliamentarism had precluded debates about presidentialism. In the following decade, the two right-wing presidents, Ozal and Demirel, briefly promoted presidentialism but failed to ... -
Phase damping destroys quantum Fisher information of W states
(Elsevier Science BV, 2014-09-05)We study the quantum Fisher information (QFI) of W states in the basic decoherence channels. We show that, as decoherence starts and increases, under i) depolarizing, QFI smoothly decays; ii) amplitude damping, QFI first ... -
A phase diagram near the NAC point in liquid crystals
(Elsevier Science SA, 2002-07-28)In this study using a mean field model we obtain the phase line equations for the NA. NC and AC transitions near the NAC point in a mixture of liquid crystals. We then fit these phase line equations to the experimental ... -
Phase transitions of kappa-carrageenan gels in various types of salts
(John Wiley & Sons Inc, 2006-11-05)Sol-gel and gel-sol phase transitions of K-carrageenan in various types of salts were studied using photon transmission technique. Here, LiCl, NaCl, KCl, MgCl2, CaCl2, and SrCl2 were chosen as the proper salts for the ... -
Phased subarray imaging for low-cost, wideband coherent array imaging
(IEEE, 2003)The front-end hardware complexity of conventional full phased array (FPA) imaging is proportional to the number of array elements. Phased subarray (PSA) imaging has been proposed as a method of reducing the hardware ...
