AIM To evaluate the effects of different curing units and light-tip tooth surface distances on the temperature increase generated during orthodontic bonding, using an infrared camera (IR) and artificial neural networks (ANN). MATERIALS AND METHODS Fifty-two freshly extracted human premolar teeth were used. Metallic orthodontic brackets were bonded to the(More)
The orthodontic "finishing" phase is recognized for the many details necessary to accomplish an excellent result. A high percentage of finishing-phase difficulties arise because of tooth size imbalances that could have been discovered and considered during the initial diagnosis and treatment planning. The aim of our study was to determine whether there is a(More)
During polysomnography, measurement of airflow and respiratory effort are essential for classifying the type of respiratory event and for evaluating the efficacy of treatment. There are various ways to measure respiratory effort, the reference technique being oesophageal manometry. This measures fluctuations in intrathoracic pressure which correspond to(More)
The desire to use the settlement areas productively along with the gradually increasing population leads the increase in the number of multi-storey buildings. With the increase of multistory buildings, the need for Elevators evenly increases. In this study, a multi-purpose training elevator was designed in order to contribute the need of training personnel(More)
In this study we propose an infrared thermography and artificial neural networks (ANNs) based method for obtaining the fatigue state of the steel specimen under bending fatigue. We use the thermal images (TIs) of the specimen under bending fatigue, taken by FLIR E45 infrared camera at 1 Hz. By processing TIs using ANNs we obtain temperatures of the(More)
Nowadays, reasons such as the gradual decrease of natural gas, coal, oil and oil derivatives, fluctuations in water levels in dams, and doubts surrounding the reliability of nuclear power plants and waste problems connected with them have caused people to search for renewable energy resources that have lower costs per unit, and do less damage to nature. To(More)
The basic solution for locating an optimal reduct is to generate all possible reducts and select the one that best meets the given criterion. Since this problem is NP-hard, most attribute reduction algorithms use heuristics to find a single reduct with the risk to overlook for the best ones. There is a discernibility function (DF)-based approach that(More)
