The progress on today's technologies has brought many advantages. Wearable technologies, telecommunication, robotic systems, 3d printers and many other applications provide great convenience for human life. Sensor technologies are also among these applications. Performing a process by controlling or co-operating the sensors also provides a significant benefit in eliminating difficulties for humans. One of the places where sensors are used is recognition systems. In the recognition process, the user materials are used such as the card, fingerprint, iris, face etc. Digital identification systems are recognition systems that can be done with various sensors and provide various benefits for the users. In the scope of this study, student attendance management system that comprises two stage control processes has been realized. At the first stage, the student ID card is read in the RFid card reader module and then the person information is checked from the database and go to the second stage. At the second stage, the fingerprint of the student is read by fingerprint sensor and the student is given the possibility to transition after the database control. Time and login information are recorded in the database when the student uses the system. Thanks to this system, it is aimed to get rid of some problems, such as sign someone else's, reading the student card someone else's, etc., in the student attendance management system.

We are studying the crystallization and annealing behavior of high performance polymers, like poly(p-pheny1ene sulfide) PPS, and poly-(etheretherketone), PEEK. Our purpose is to determine whether PPS, which is similar in many ways to PEEK, undergoes reorganization during annealing. In an effort to address the issue of reorganization, we are studying solution grown single crystals of PPS as model materials.Observation of solution grown PPS crystals has been reported. Even from dilute solution, embrionic spherulites and aggregates were formed. We observe that these morphologies result when solutions containing uncrystallized polymer are cooled. To obtain samples of uniform single crystals, we have used two-stage self seeding and solution replacement techniques.
