Widely unable dual-wavelength operation of Tm:YLF, Tm:LuAG, and Tm:YAG lasers using off-surface optic axis birefringent filters
(Optical Soc Amer, 2018)
In this work, we have demonstrated dual-wavelength continuous-wave laser operation in diode-end-pumped Tm:YLF, Tm:LuAG, and Tm:YAG lasers. A 3-mm-thick quartz birefringent filter with an optical axis 45 degrees to the ...
Peak-to-average-power-ratio (PAPR) reduction methods with wavelet transform in MIMO-OFDM
(Taylor & Francis Ltd, 2018)
This study is based on the comparison of the results with an analysis method recommended for the Peak-to-Average-Power-Ratio (PAPR) reduction methods. This is one of the most significant problems in the Multiple Input-Multiple ...
TRCyberLab: An infrastructure for future internet and security studies
(Ieee, 2018)
The digital world is continuously changing, and new technologies affecting every aspect of our life. in order to keep up with these changes and have some impact and/or control over it; we must conduct advanced research on ...
Localization of leakages in underwater natural gas pipelines for multipath propagation
(Ieee, 2018)
Underwater natural gas pipelines (UNGPs) are frequently used to transport natural gas, which is an important energy resource. UNGPs can get punctured because of several reasons such as especially corrosion and their ...
Classification of motor imaginary based near-infrared spectroscopy signals
(Ieee, 2018)
Near Infrared spectroscopy (NIRS) is a brain imaging technique that measures hemodynamic activity in the human brain cortex with special wavelengths (infrared) in the light. the use of this technique in brain-computer ...
A multiple-band perfect absorber for SEIRA applications
(Elsevier Science Sa, 2018)
Recently perfect absorbers (PAs) have received significant interest due to their characteristics of complex electric permittivity (epsilon) and magnetic permeability (mu). By rationally designing these artificial structures, ...
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 ...
