Low-cost multimode diode-pumped Tm:YAG and Tm:LuAG lasers
(2019)
We report a continuous-wave operation of Tm:YAG and Tm:LuAG lasers pumped with a low-cost, multimode AlGaAs laser diode. First, the lifetime and the absorbance behavior of 5 mm, 6% Tm3+ -doped YAG and LuAG crystals were ...
Thermoelectric transport behaviours of n-type Mg-2 (Si,Sn,Ge) quaternary solid solutions
(Keai Publishing Ltd, 2019)
Mg2X (X=Si, Sn, and Ge) based systems have attracted widespread attention owing to their various benefits in thermoelectric applications. in particular, to date, ternary Mg2X based solid solutions have become one of the ...
Centrifugally spun silica (SiO2) nanofibers for high-temperature air filtration
(Taylor & Francis Inc, 2019)
In this study, silica-based nanofibers were produced via centrifugal spinning (C-spin) and subsequent calcination. the produced heat resistant media was challenged with NaCl nanoparticles to investigate their filtration ...
Low-cost multi-mode diode pumped Tm:YLF laser: Multi-color & Q-switching operations
(Elsevier, 2019)
In this paper, we report a low-cost multi-mode AlGaAs laser diode pumped broadly-tunable solid-state Tm:YLF laser at room-temperature operating in two different regimes: multi-color and Q-switching. A low-cost multimode ...
Effect of annealing temperature on K-shell X-ray fluorescence parameters of zinc oxide thin films prepared by the sol-gel method
(Taylor & Francis Inc, 2019)
Zinc oxide thin films were grown on a glass substrate by a sol-gel process using a spin-coating technique. the obtained thin films were annealed between 350 degrees C and 550 degrees C in 50 degrees C steps and were then ...
A robust and subject-specific sequential forward search method for effective channel selection in brain computer interfaces
(Elsevier Science Bv, 2019)
Background: the input signals of electroencephalography (EEG) based brain computer interfaces (BCI) are extensively acquired from scalp with a multi-channel system. However, multi-channel signals might contain redundant ...
Received signal strength difference based leakage localization for the underwater natural gas pipelines
(Elsevier Sci Ltd, 2019)
Natural gas is an indispensable energy resource of today. It is transported from production centers to the consumption areas extensively using underwater pipelines. Several reasons such as aging, internal and external ...

Kararlı durumda seri kapasitörlerin iletim şebekesine etkilerinin incelenmesi
(2019)
Artan nüfus ve gelişen sanayi ile birlikte elektrik enerjisi ihtiyacı günden güne artmaktadır. Bu talebin karşılanması için yeni üretim tesisleri birincil enerji kaynaklarına yakın yerlerde kurulmakta ve iletim şebekesi ...
Hava hedeflerinin tespiti için yakın gerçek zamanlı çoklu frekans bandı destekli pasif radar sisteminin geliştirilmesi
(Gazi Univ, Fac Engineering Architecture, 2019)
Passive radars are radar systems that do not have a transmitter of their own but can identify and follow targets by using the transmitters located in the environment. the interest in passive radar systems, whose history ...
