2D correlated diffusion process for mobility modeling in mobile networks
Çakar, Tunç; Baykal, Buyurman; Department of Electrical and Electronics Engineering (2004)
This thesis introduces a novel mobility model based on so called أ2D correlated diffusion processؤ. In this model, motion components over x and y axes are dependent. Joint density function of the process is derived. The expected exit time from an arbitrary domain is characterized by a boundary value problem. Analytical solution of this problem is given for a specific case. Numerical solution of the problem is presented by several examples. The results obtained in these examples are verified by simulations. ...
3D Porous Composite Scaffold of PCL-PEG-PCL/Sr2+ and Mg2+ Ions Co-Doped Borate Hydroxyapatite for Bone Tissue Engineering
Yedekçi, Buşra; Evis, Zafer; Tezcaner, Ayşen; Department of Engineering Sciences (2021-9-6)
Bioceramic/polymer composite systems have gained importance in treating hard tissue damages using bone tissue engineering (BTE). In this context, it was aimed to develop 3D porous composite PCL-PEG-PCL scaffolds containing different amounts of B, Sr and Mg multi-doped hydroxyapatite (HA) that can provide bone regeneration in the bone defect area and to investigate the effect of both the amount of inorganic phase and the porosity on the mechanical and the biological properties. B-Sr-Mg multi-doped HAs were s...
3D porous bioceramic based boron-doped hydroxyapatite/baghdadite composite scaffolds for bone tissue engineering
Jodati, Hossein; Evis, Zafer; Tezcaner, Ayşen; Alshemary, Ammar Z.; Motameni, Ali (2023-04-01)
Making composite scaffolds is one of the well-known methods to improve the properties of scaffolds used in bone tissue engineering. In this study, novel ceramic-based 3D porous composite scaffolds were successfully prepared using boron-doped hydroxyapatite, as the primary component, and baghdadite, as the secondary component. The effects of making composites on the properties of boron-doped hydroxyapatite-based scaffolds were investigated in terms of physicochemical, mechanical, and biological properties. T...

2D simulations based on the general time dependent reciprocal relation and initial experiments for LFEIT /
Karadaş, Mürsel; Gençer, Nevzat Güneri; Department of Electrical and Electronics Engineering (2014)
In this study, the new imaging modality Lorentz Field Electrical Impedance Tomography (LFEIT) is investigated. In LFEIT, the main aim is finding the conductivity distribution of different tissues. This method is based on the development of the current density distribution in the conductive medium. To develop the current density, the object is located in a static magnetic field and pressure wave due to an ultrasonic transducer develops particle movements inside the body. As a result, a velocity current distr...
