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 ...
Exhibition of polarization conversions with asymmetric transmission theory, natural like chiral, artificial chiral nihility and retrieval studies for K- and C-band radar applications
(Indian Academy of Sciences, 2019)
In this study, asymmetric transmission, natural chirality phenomena and a retrieval study with chiral metamaterials (MTMs) are numerically and experimentally focussed, investigated and discussed by examining the polarization ...
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 ...
Multifarious correlations for p-adic gamma function and weighted q-Daehee polynomials
(Maejo University, 2019)
Diverse relations and identities for p-adic gamma function and p- adic Euler constant by means of weighted p-adic q-integral on pZ and Mahler expansion of the function are investigated. Then several correlations and formulas ...
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 ...
Determinants of Financial Risk: An Empirical Application on Low-Cost Carriers
(Sciendo, 2019)
The airline industry has entered a rapid development and transformation process, especially after the Second World War. In this process, it is seen that the market structure changed and many private airlines were established. ...
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 ...
