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...
Frequency Tunable Metamaterial Designs Using Near Field Coupled SRR Structures in the Terahertz Region
Ekmekci, Evren; Strikwerda, A. C.; Fan, K.; Keiser, G.; Zhang, Xin; Turhan-Sayan, G.; Averitt, Richard D. (2011-05-06)
We present frequency tunable metamaterials at terahertz frequencies using broadside-coupled split ring resonators. Frequency tuning, arising from changes in near field coupling, is obtained by in-plane displacement between...
Control of Multi-Sources Energy PV/Fuel Cell and Battery Based Multi-Level Inverter for AC Load
Koulali, Mostefa; Boumediene, Bachir; Negadi, Karim; Pourkeivannour, Siamak; Mankour, Mohamed; Smaili, Attalah (2019-01-01)
The considered system was implemented in the Matlab/Simulink, the results show the effectiveness of the proposed method and can be realized with experimented setup. This work deals with the study of an electrical energy pr...
Endo-VMFuseNet: A Deep Visual-Magnetic Sensor Fusion Approach for Endoscopic Capsule Robots
Turan, Mehmet; Almalioglu, Yasin; Gilbert, Hunter B.; Sari, Alp Eren; Soylu, Ufuk; Sitti, Metin (2018-05-25)
In the last decade, researchers and medical device companies have made major advances towards transforming passive capsule endoscopes into active medical robots. One of the major challenges is to endow capsule robots with ...
