A PV Module with Embedded Humidity Sensors to Detect Moisture Ingress Elbeheiry, Nabila; Turan, Raşit; Balog, Robert S. (2025-01-01) Moisture ingress in photovoltaic (PV) modules reduces power output, accelerates material degradation, and poses safety risks, including electric shock, arcing, and fire hazards, by exposing high-voltage components. PV modu...
Ballistic Photon Imaging by Direct Two-Photon Sensor Gating Kadan, Viktor; Dmytruk, Andriy; Akhtaryarazar, Darya; Dmytruk, Igor; Goodarzi, Arian; Pavlov, Ihor (2025-01-01) Various nonlinear temporal gating techniques [e.g., 1], which rely on the cross-correlation between signal and gating pulses (or auto-correlation if gating the pulse with itself), effectively address the slow response time...
High Altitude Balloon-Radiation Monitoring and Test Platform YİB: Design and Flight Results Demirköz, Melahat Bilge; Arslan, Mehlika Zeynep; Demircan, Bahadir Han; Kilic, Ugur; Yilmaz, Nazire Seyma; Ada, Alparslan (2025-01-01) Understanding atmospheric radiation is essential for evaluating both natural and human-induced effects on Earth's environment. The YİB high-altitude balloon platform is designed to measure radiation up to an altitude of 38...
Active Tunable Extraordinary Optical Transmission in the Visible Regime Asif, Hira; TAŞGIN, MEHMET EMRE; Bek, Alpan; ŞAHİN, RAMAZAN (2025-01-01) Active tuning of components in the photonic integrated circuits (PICs) is crucial for achieving programmable devices, especially in the visible regime [1]. However, the operational bandwidth and response time of photonic d...

The SND@LHC experiment at CERN Güler, Ali Murat (2024-03-22) SND@LHC is proposed to exploit the high flux of energetic neutrinos of all flavours from the LHC in a hitherto unexplored pseudo-rapidity region of 7.2 < η < 8.4, complementary to all the other experiments at the LHC. The ...
NA65(DsTau): study of tau neutrino production in p-A interactions Güler, Ali Murat (2024-03-22) The DsTau (NA65) experiment at CERN was proposed to measure an inclusive differential cross-section of Ds production in p-A interactions. As this process is a main source of tau neutrino production, its study is necessary ...
2D Malzemelere Dayalı Terahertz Plazmonik Yükselteçlerin Nano Ölçekte Geliştirilmesi Altan, Hakan (2024-03-13)
On the conditions of applicability of commonly used modification of a fluid model for glow discharge Kudryavtsev, A.; Rafatov, İsmail; Yuan, C. (2024-01-01) The reliability of a numerical model is determined by its the least accurately known component. Such a component in fluid models of glow discharges is the description of electrons, which are far from equilibrium. This is e...
Enhanced Photoluminescence from Quantum Emitter-Nanoplasmonic Antenna Hybridization by a Facile Fabrication Method Genç, Sinan; Yilmaz, Alpay; Fernandez, Carlos Rodriguez; Caglayan, Humeyra; Bek, Alpan (2024-01-01) Gaps between tiny metallic nanostructures create strong local fields and small mode volumes, known as hybrid plasmonic modes.
