Performance Analysis of Faster than Symbol Rate Sampling in 1-Bit Massive MIMO Systems
Üçüncü, Ali Bulut; Yılmaz, Ali Özgür (2017-05-25)
Low resolution analog-to-digital converters (ADC) attracted much attention lately for massive multiple-input multiple-output (MIMO) communication and systems with high bandwidth. Especially, 1-bit ADCs are suitable for such systems due to their low power consumption and cost. In this study, we illustrate the benefits of using faster than symbol rate (FTSR) sampling in an uplink massive MIMO system with 1-bit ADCs in terms of symbol error rate (SER). We show that FTSR sampling provides about 4 dB signal-to-n...
Residual stress and Young's modulus measurement of capacitive micromachined ultrasonic transducer membranes
Yaralioglu, GG; Ergun, AS; Bayram, Barış; Marentis, T; Khuri-Yakub, BT (2001-01-01)
Membranes supported by posts are used as vibrating elements of capacitive micromachined ultrasonic transducers (CMUTs). The residual stress built up during the fabrication process determines the transducer properties such as resonance frequency, collapse voltage, and gap distance. Hence, it is important to evaluate and control the stress in thin film CMUT membranes. The residual stress in the membrane causes significant vertical displacements at the center of the membrane. The stress bends the membrane post...
Skew configurations of lines in real del pezzo surfaces
Zabun, Remziye Arzu; Finashin, Sergey; Department of Mathematics (2014)
By blowing up projective plane at n<9 points which form a generic configuration, we obtain a del Pezzo surface X of degree d=9-n with a configuration of n skew lines that are exceptional curves over the blown-up points. The anti-canonical linear system maps X to a projective space of dimension d, P^{d}, and the images of these exceptional curves form a configuration of n lines in P^{d}. The subject of our research is the correspondence between the configurations of n generic points in a real projective plan...
Analysis of Confidence Levels and Application Success Rates in Simulator-Based Dental Anesthesia Education Among Undergraduate Dental Students
Vural, Çağıl; Bozkurt, Poyzan; Vardar Acar, Ceren; Üçok, Cahit (2021-06-01)
Purpose: We investigated the confidence levels of undergraduate dental students who used dental anesthesia simulators and patient reports of undergraduate dental students' confidence levels in delivering anesthesia injections, in comparison with undergraduate dental students who did not use dental anesthesia simulators. We also investigated application success rates. Materials and Methods: The study was carried out in the dental anesthesia simulator laboratory and in the faculty clinics of the Faculty of De...
Borate modified bioglass containing scaffolds for dental tissue engineering applications
Moonesi Rad, Reza; Tezcaner, Ayşen; Evis, Zafer; Department of Biotechnology (2018)
Dental tissue engineering has gained increasing attention in recent years. Dentures or implants are used as replacements of the lost teeth. High cost of these restorations and rejection possibility of the implants are their main drawbacks. For this reason, a regenerative approach for repairing of the damaged dentin-pulp complex or generating a new tissue is needed. The properties associated with bioglass like biocompatibility and bioactivity are very attractive for dental applications. In this thesis, bioac...
