Irreversibility line and flux relaxation in Bi:2223/Ag tape prepared by CTFF technique: H//c axis
(Springer Link, 2010)
We have studied flux dynamics in Bi:2223/Ag tape prepared by the CTFF technique in the orientation of H//c axis. Irreversibility line (IL) of a Bi:2223/Ag tape has been determined from AC susceptibility and the DC magnetization ...
Hydrogen production system design with synchronous buck converter
(IEEE, 2010)
Nowadays, the growing energy needs and the decreasing fossil fuels have made inevitable the use of new and renewable energy. The high cost of the renewable energy sources led to the need to develop more efficient and cheaper ...
Efficient calculation of boys integrals
(2010)
An efficient procedure has been presented for the calculation of Boys integrals by dividing the integral region [0, 1] into several parts. The obtained formula includes factorials, exponentials and a well known auxiliary ...
The influence of substrate temperature on electrical properties of Cu/CdS/SnO2 Schottky diode
(Elsevier, 2011)
Polycrystalline CdS samples on the SnO2 coated glass substrate were obtained by vacuum evaporation method at low substrate temperatures (T S=200 and 300 K) instead of the commonly used vacuum evaporation at high substrate ...
A novel photovoltaic PV-powered battery charging scheme for electric vehicles
(IEEE, 2011)
The paper presents a novel photo-voltaic PV powered battery charging station. The flexible scheme developed by the first Author is controlled by a FACTS-based Green Plug-Filter Compensator GPFC to ensure efficient utilization ...
Gamma ray and neutron shielding properties of some concrete materials
(Elsevier, 2011)
Shielding of gamma-rays and neutrons by 12 concrete samples with and without mineral additives has been studied. The total mass attenuation and linear attenuation coefficients, half-value thicknesses, effective atomic ...
Annual effective dose and concentration levels of gross α and β in various waters from Samsun, Turkey
(Elsevier, 2011)
Samsun city which is between the deltas where YeŞilirmak and Kizilirmak rivers run out, exists in the middle part of Black Sea's costal way. It is the biggest city of the Black Sea Region in terms of population, industry, ...
Determination of mass attenuation coefficients for natural minerals from different places of Turkey
(2011)
The mass attenuation coefficients (?m) for some natural minerals taken from different places of Turkey were measured at various low photon energies. The Am-241 radioactive source and Zr and Cd secondary exciter are used ...
Radionuclides and heavy metals concentrations in Turkish market tea
(Elsevier, 2011)
Tea is one of the most popular beverages in the world. The Eastern Black Sea Region of Turkey is one of the main tea producers in Turkey and the fifth in the world. Thus, the chemical components in tea have received great ...
Spectrum analyzer measurement technique for safety evaluation on wireless communication systems
(IEEE, 2011)
In this paper, general information about, unionized radiation, wireless communication systems and electromagnetic fields are given. The safety of mobile phones has been evaluated in terms of specific absorption ratio (SAR). ...
