On the classification of scalar evolution equations with non-constant separant
(IOP Publishing Ltd, 2017)The ` separant' of the evolution equation u(t) = F where F is some differentiable function of the derivatives of u up to order m is the partial derivative partial derivative F/partial derivative u(m) where um u(m) = partial ... -
On the inverse point-source problem of the poisson equation
(Istanbul University, 2005)In this work a basic inverse heat conduction problem of a simple 2-D model with steady state heat source is taken into view. The physical problem is for a square region with uniform thermophysical properties and a point ... -
On the selection of ınterpolation points for rational Krylov Methods
(Springer-Verlag Berlin, 2012)We suggest a simple and an efficient way of selecting a suitable set of interpolation points for the well-known rational Krylov based model order reduction techniques. To do this some sampling points from the frequency ... -
On the Time Shift Phenomena in Epidemic Models
(Frontiers Media Sa, 2020)In the standard Susceptible-Infected-Removed (SIR) and Susceptible-Exposed-Infected-Removed (SEIR) models, the peak of infected individuals coincides with the inflection point of removed individuals. Nevertheless, a survey ... -
On the uniqueness of epidemic models fitting a normalized curve of removed individuals
(Springer Heidelberg, 2015)The susceptible-infected-removed (SIR) and the susceptible-exposed-infected-removed (SEIR) epidemic models with constant parameters are adequate for describing the time evolution of seasonal diseases for which available ... -
On the uniqueness of the octonionic instanton solution on conformally flat 8-manifolds
(IOP Publishing Ltd, 2016)Let M be an 8-manifold and E be an SO(8) bundle on M. In a previous paper [F. Ozdemir and A.H. Bilge, "Self-duality in dimensions 2n > 4: equivalence of various definitions and the derivation of the octonionic instanton ... -
On-Line Transient Stability Assessment Using Matlab Parallel Programming Environment
(IEEE, 2010)Transient Stability Assessment (TSA) is the major part of Dynamic Security Assessment (DSA) in an electric power system. On-line TSA has gained more importance for power system security in last two decades. The decreasing ... -
One Battle and Two Accounts: The Turkish Brigade at Kunu-ri in November 1950
(Soc Military History, 2016)The recent revival of academic and popular interest in the Korean War in Turkey has played an important role in instigating the production of new books and documentaries. In Turkish accounts the Battle of Kunu-ri (November ... -

(Uluslararası İlişkiler Konseyi Derneği, 2012)During the last decade billions of dollars have been spent to increase security measures in the United States. New institutions including a department for homeland security have been established new security tools have ... -
Ontology-based data acquisition model development for agricultural open data platforms and implementation of OWL2MVC tool
(Elsevier, 2020)In the open data world, it is difficult to collect data in compliance with a certain data model that is of interest to different types of stakeholders within a domain like agriculture. Ontologies that provide broad ... -
Open data in agriculture: Sustainable model development for hazelnut farms using semantics
(Institute of Electrical and Electronics Engineers Inc., 2018)Turkey accounts for 75% of the global hazelnut production and 70-75% of the exportation. Taking into account the socioeconomic importance of hazelnut, the stakeholders of hazelnut domain still have problems such as ... -
An open software architecture of neural networks: Neurosoft
