Nanosecond colloidal quantum dot lasers for sensing
Guilhabert, B.; Foucher, C.; Haughey, A-M.; Mutlugun, E.; Gao, Y.; Herrnsdorf, J.; Sun, H. D.; Demir, H. V.; Dawson, M. D.; Laurand, N. (2014-03-24)
Low-threshold, gain switched colloidal quantum dot (CQD) distributed-feedback lasers operating in the nanosecond regime are reported and proposed for sensing applications for the first time to the authors' knowledge. The l...
Learning to Navigate Endoscopic Capsule Robots
Turan, Mehmet; Almalioglu, Yasin; Gilbert, Hunter B.; Mahmood, Faisal; Durr, Nicholas J.; Araujo, Helder; Sari, Alp Eren; Ajay, Anurag; Sitti, Metin (Institute of Electrical and Electronics Engineers (IEEE), 2019-07-01)
Deep reinforcement learning (DRL) techniques have been successful in several domains, such as physical simulations, computer games, and simulated robotic tasks, yet the transfer of these successful learning concepts from s...
Development of algorithms and software for forecasting, nowcasting and variability of TEC
Tulunay, E; Senalp, ET; Cander, LR; Tulunay, YK; Bilge, AH; Mizrahi, E; Kouris, SS; Jakowski, N (2004-01-01)
Total Electron Content (TEC) is an important characteristic of the ionosphere relevant to communications. Unpredictable variability of the ionospheric parameters due to various disturbances limits the efficiencies of commu...
5G Radio Access Network Architecture: Design Guidelines and Key Considerations
Marsch, Patrick; Da Silva, Icaro; Bulakci, Omer; Tesanovic, Milos; El Ayoubi, Salah Eddine; Rosowski, Thomas; Kaloxylos, Alexandros; Boldi, Mauro (2016-11-01)
While there is clarity on the wide range of applications that are to be supported by 5G cellular communications, and standardization of 5G has now started in 3GPP, there is no conclusion yet on the detailed design of the o...
Spectrum Pooling in MmWave Networks: Opportunities, Challenges, and Enablers
Boccardi, Federico; Shokri-Ghadikolaei, Hossein; Fodor, Gabor; Erkip, Elza; Fischione, Carlo; Kountouris, Marios; Popovski, Petar; Zorzi, Michele (2016-11-01)
Motivated by the specific characteristics of mmWave technologies, we discuss the possibility of an authorization regime that allows spectrum sharing between multiple operators, also referred to as spectrum pooling. In part...
Musical mirror-symmetrical movement tasks: comparison of rhythm versus melody-playing
Tokgoz, Serhat; Aydogdu, Demet; Ilhan, Barkin; Sahin, Yusuf; Bariseri, Nurtug; Ozturkler, Batu Mehmet; ÇUKUR, TOLGA (Ovid Technologies (Wolters Kluwer Health), 2020-05-07)
Bimanual mirror-symmetrical movement (MSM) is relatively easy to control movement. Different MSM tasks may have different activations and interhemispheric interactions. The purpose of this study is to compare anatomo-physi...
Electromagnetic absorbance properties of a textile material coated using filtered arc-physical vapor deposition method
ESEN, MEHMET; İLHAN, İLHAMİ; KARAASLAN, MUHARREM; ÜNAL, EKİN ANIL; Dincer, F.; Sabah, C. (2015-09-01)
We explore the structure of a textile absorber in terms of its electromagnetic and absorption properties in the microwave region. Its absorption characteristics are similar to those reported for various metamaterial-based ...
Demonstration of optical nonlinearity in InGaAsP/InP passive waveguides
Saeidi, Shayan; Rasekh, Payman; Awan, Kashif M.; Tugen, Alperen; Huttunen, Mikko J.; Dolgaleva, Ksenia (Elsevier BV, 2018-10-01)
We report on the study of the third-order nonlinear optical interactions in InxGa1-xAsyP1-y/InP strip-loaded waveguides. The material composition and waveguide structures were optimized for enhanced nonlinear optical inter...
Metamaterial absorber-based multisensor applications using a meander-line resonator
AKGÖL, OĞUZHAN; ALTINTAŞ, OLCAY; Dalkilinc, Elif Eda; ÜNAL, EMİN; KARAASLAN, MUHARREM; Sabah, Cumali (2017-08-01)
A metamaterial (MTM) absorber-based multifunctional sensor is numerically and experimentally realized using meander-line resonators. The proposed sensor device can be used to measure pressure, density, and humidity with pe...
Zinc oxide-tungsten-based pyramids in construction of ultra-broadband metamaterial absorber for solar energy harvesting
ÜNAL, EMİN; BAĞMANCI, MEHMET; KARAASLAN, MUHARREM; AKGÖL, OĞUZHAN; ARAT, HÜSEYİN TURAN; Sabah, Cumali (2017-06-01)
A new broadband absorber is investigated for the entire frequency domain of solar light (infrared, visible light and ultraviolet). While current absorbers in the literature have limited operation frequencies, investigated ...
