    Dose and fading time estimation of glass ceramic by using artificial neural network method
    (2021) Işık, İbrahim; IŞIK, Esme; Toktamış, Hüseyin
    Abstract: Ceramic materials commonly used for dental prosthetics and restorations shows luminescent properties. Dental ceramics are considered the most natural-looking restorative materials for aesthetic rehabilitation due to their transparency. They are commonly used for dose response and fading assessment by using thermoluminescence method in various fields of dosimetric applications. In present study, we use artificial neural networks (ANN) toolbox of Matlab to predict irradiation dose and fading time using glow curve data from dental glass ceramic which is thermoluminescent (TL) dosimetric material. Temperature, dose value and fading time are used for input and TL intensity used for output component of the proposed ANN model. 18 neurons are used for hidden layer to analyze the experimental results of the model. Experimental and simulation results are compared and similarity is found as about 99 % in this present study.

    Effect of the Viscocity on Molecule Reception Ratio for Mobile Nano Systems
    (2021) IŞIK, Esme; Işık, İbrahim; TAĞLUK, M. Emin
    Abstract: Studies regarding communication of the nano-devices/machines are considered to highlycontribute to the developments in the field of nano-technology. Therefore, in this study, softwarebased a new model using nano-machine that could potentially be used in nano-scale systems wasdeveloped and analyzed in terms of communication performance. The information about the carrierparticles used in such communication systems consists of biological components such as DNA andprotein components. MC model that can possibly be used in nano-scale systems is analyzed in termsof channel performance of communication model such as viscosity of the medium. The physicalproperties of the proposed channel model such as viscosity is analyzed with respect to the ratio ofreceived molecules in the duration of first symbol slot and number of received molecules using themobile point transmitter and spherical receiver. As a result, the probability of a molecule receptionof the receiver and number of received molecules increase with decreasing viscosity.
