Improved MPPT method to increase accuracy and speed in photovoltaic systems under variable atmospheric conditions
(Elsevier Sci Ltd, 2019)
The changes in temperature and radiation cause visible fluctuations in the output power produced by the photovoltaic (PV) panels. It is essential to keep the output voltage of the PV panel at the maximum power point (MPP) ...
Simulation of diesel hybrid electric vehicle containing hydrogen enriched CI engine
(Elsevier, 2019)
Hydrogen enrichment on diesel engines is a proven solution for both minimizing the undesirable emissions and fuel consumptions. Also, hybrid electric vehicles which manufactured for the same goal too, are playing an important ...
Effect of different cryoprotectants (glycerol, methanol and dimethyl sulfoxide) on post-thaw quality, viability, fertilization ability and DNA damage of cryopreserved nile tilapia (oreochromis niloticus) spermatozoa
(Cryo Letters, 2019)
BACKGROUND: Cryopreservation of sperm from different fish species requires different protocols. Therefore, it is necessary to perform studies to establish reliable procedures for each species. OBJECTIVE: Experiments were ...
Exergy analysis of a natural gas fuelled gas turbine based cogeneration cycle
(Inderscience Enterprises Ltd, 2019)
In this paper, the monthly-based annual performance of a natural gas fuelled gas turbine-based cogeneration cycle was analysed. The performance analysis of the system was investigated in three steps. First, the real system ...
Chemical Liquid and Transformer Oil Condition Sensor Based on Metamaterial-Inspired Labyrinth Resonator
(Electrochemical Society Inc., 2019)
In this study, the labyrinth resonator based chemical liquid and transformer oil condition sensor are presented in a microwave frequency range both numerically and experimentally. The transmission coefficient is observed ...
Wide band fractal-based perfect energy absorber and power harvester
(Wiley, 2019)
In this article, a novel wide band polarization and incident angle independent metamaterial absorber (MA) and energy harvesting applications which operates at C (4GHz-8 GHz) and X (8GHz-12 GHz) is proposed. The unit-cell ...
Semi-empirical determination of Kα1,2, Kβ1,3, and Kβ2,4 X-ray natural line widths for various elements between 29 ≤ Z ≤ 74 at 123.6 keV
(Taylor & Francis Inc, 2019)
In this study, K-alpha 1,K-2, K-beta 1,K-3, and K-beta 2,K-4 X-ray natural line widths for various elements were determined semi-empirically at 123.6 keV by using K shell fluorescence yields obtained from energy dispersive ...
Determination of optimum post embedment depth for C120 steel posts using field and full scale crash test
(Taylor & Francis Ltd, 2019)
C120 steel sections are the most widely used post shapes in European guardrail designs. The design length of these posts is determined based on guardrail containment level and engineering judgment. The soil properties where ...
Metamaterial absorber sensor design by incorporating swastika shaped resonator to determination of the liquid chemicals depending on electrical characteristics
(Elsevier, 2019)
In this work, sensor abilities of the metamaterial absorber based on swastika shaped resonator are developed both theoretically and experimentally at X-band frequency range. The structure is consisted of a swastika shaped ...
