P-T phase diagram for NH₄F
(Editions Scientifiques Medicales Elsevier, 2002-04)In this study we obtain a P-T phase diagram of NH4F using the mean-field theory. We fit our calculated phase line equations to the experimental P-T phase diagram. By choosing appropriately the coefficients in the free-energy ... -
Painting education & artistic evolution
(Elsevier Science BV, 2012)Art is the most effective way of expressing human emotions. It should also be an excellent application of traditional or technological tools. In our presentation-research we will be focusing on painting, painting education ... -
Palmprint verification using SIFT majority voting
(Springer-Verlag, 2012)In this paper we illustrate the implementation of a robust, real-time biometric system for identity verification based on palmprint images. The palmprint images are preprocessed to align the major axes of hand shapes and ... -
Paradox of optimism: opposition coordination against autocratic incumbents in Turkey’s 2019 and 2023 elections
(Routledge, 2024)In the 2019 local and 2023 general elections, Turkey’s opposition parties joined forces in pursuit of a common objective: to oust autocratic incumbents and democratize the political system. While they achieved noteworthy ... -
A parallel implementation: Real space Green's function technique
(Sage Publications, 2007-04)We develop an MPI-based parallel algorithm to implement the real space Green's function technique for calculating the vibrational density of states corresponding to a solid. The Hamiltonian describing the interactions ... -
Parallel univariate decision trees
(Elsevier B.V., 2007-05-01)Univariate decision tree algorithms are widely used in data mining because (i) they are easy to learn (ii) when trained they can be expressed in rule based manner. In several applications mainly including data mining, the ... -
Parameter estimation with Dzyaloshinskii–Moriya interaction under external magnetic fields
(Springer, 2020-02-01)We study the effects of external magnetic fields on the precision of parameter estimation with thermal entanglement of two spins in XX model, in the presence of Dzyaloshinskii–Moriya (DM) interaction. Although DM interaction ... -
A parametric approach to construct two-variable positive real impedance functions for the real frequency design of mixed lumped-distributed matching networks
(IEEE, 2004)In this paper, a parametric approach to construct two-variable positive real driving point impedance functions characterizing lossless ladder networks with mixed lumped and distributed elements is presented. The proposed ... -
A parametric approach to describe distributed two-ports with lumped discontinuities for the design of broadband MMIC's
(IEEE, 2003)This paper addreses the use of mixed lumped and distributed elements in the matching equalizers of broadband microwave communication subsytems in MMIC realizations. Construction of two-variable scattering functions for ... -
Parametrik ve parametrik olmayan verimlilik değerlendirmesi ve karşılaştırılması: Türkiye elektrik santralleri örneği
(2017)Çalışma boyunca Türkiye’deki çeşitli enerji santrallerinin operasyonel ve uzun vadeli yatırım performansları Stokastik Sınır Analiz (SSA) ve Veri Zarflama Analizi (VZA) kullanılarak karşılaştırıldı. Veri kümesi, özel ve ... -
Paraoxonase (PON1) L55M and Q192R polymorphisms in major depression and bipolar affective disorder
(Univ Sao Paulo, 2017-05/06)Background: 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 ... -
Paraoxonase (PON1) L55M and Q192R polymorphisms in major depressive disorder and bipolar disorder
(Psikofarmakoloji Derneği adına Mesut Çetin, 2017)Objective: Oxidative and nitrosative stress pathways, along with immune-inflammatory response, might play an important role in the pathogenic mechanisms underlying major depressive disorder and bipolar disorder. The aim ... -
Parçacık süzgeçleme ile hedef izleme uygulamasında topak çizelgeleme
