Deep-collapse operation of capacitive micromachined ultrasonic transducers
(IEEE, 2011)Capacitive micromachined ultrasonic transducers (CMUTs) have been introduced as a promising technology for ultrasound imaging and therapeutic ultrasound applications which require high transmitted pressures for increased ... -
Development and characterization of a direct detection fiber optic distributed acoustic sensor
(Bilkent University, 2018-09)Phase-sensitive optical time domain re ectometer (ø-OTDR) based distributed acoustic sensor (DAS) systems have attracted increasing attention in recent years due to their remarkable advantages in a wide range of industrial ... -
Distributed channel aware link scheduling for CSMA based wireless networks with time-varying channels and delay sensitive applications
(Bilkent University, 2011)In wireless networks, interference between neighboring links is an important issue. The link scheduling algorithm controls the interference between neighboring links such that no adjacent links can be concurrently active. ... -
Field test and fading measurement of a distributed acoustic sensor system over a 50 km-long fiber
(SPIE - International Society for Optical Engineering, 2018)In this study, we present a direct detection distributed acoustic sensor based on phase-sensitive optical time domain reflectometer (φ-OTDR) with long sensing range and high signal-to-noise ratio (SNR), which is field-tested ... -
Maximization of average number of correctly received symbols over multiple channels in the presence of idle periods
(Elsevier Inc., 2016)In this study, optimal channel switching (time sharing) strategies are investigated under average power and cost constraints for maximizing the average number of correctly received symbols between a transmitter and a ... -
Multipath fading effect on terrestrial microwave LOS radio links
(IEEE, 2015-07)In this paper, the calculation of both the total received power with the effect of the ground reflection and the fade margin to find out the link availability for terrestrial microwave LOS (line-of-sight) radio links is ... -
Optimal power allocation for average detection probability criterion over flat fading channels
(Institute of Electrical and Electronics Engineers Inc., 2017)In this paper, the problem of optimal power allocation over flat fading additive white Gaussian noise channels is considered for maximizing the average detection probability of a signal emitted from a power constrained ...
