Effects of the Stroke Bore Ratio on the Performance Parameters of a Dual-Spark-Ignition (DSI) Engine
(Energy & Fuels (ACS Publishers), 2009)
In this study, the effects of the stroke/bore (S/B) ratio on the performance parameters of an engine having dual-spark ignition (DSI) were investigated theoretically by using a quasi-dimensional thermodynamic cycle model. ...
Estimating earthquake hazard parameters from instrumental data for different regions in and around Turkey
(Engineering Geology, 2009)
We conducted a study of the spatial distributions of seismicity and earthquake hazard parameters for Turkey and the adjacent areas, applying the maximum likelihood method. The procedure allows for the use of either historical ...
Effects of truss behaviour on critical temperatures of welded steel tubular truss members exposed to uniform fire
(Engineering Structures, 2015)
This paper presents the results of a numerical investigation into the behaviour of welded steel tubular truss at elevated temperatures. The purpose is to assess whether the current method of calculating truss member limiting ...
Exergetic Analysis of Using Gaseous Fuels in Spark Ignition Engines
(Journal of Thermophysics and Heat Transfer (The American Institute of Aeronautics and Astronautics), 2014)
This paper aims to investigate the use of alternative gaseous fuels in spark ignition engines via an exergy analysis.A quasi-dimensional two-zone thermodynamic cycle model is used for this purpose. The intake and exhaust ...
Fabrication and properties of dense ex situ magnesium diboride bulk material synthesized using spark plasma sintering
(IOP PUBLISHING LTD, DIRAC HOUSE, TEMPLE BACK, BRISTOL BS1 6BE, ENGLAND, 2009-09)
High density ex situ magnesium diboride bulks were synthesized from commercial MgB(2) powder using spark plasma sintering under a range of applied uniaxial pressures between 16 and 80 MPa. The microstructure was characterized ...
Formation of skarns at Gümüşhane (Northeastern Turkey)
(Neues Jahrbuch für Mineralogie-Abhandlungen, 2011)
Skarn deposits are located in the NE Black Sea region of Turkey belonging to the Alpin metallogenic province. The Fe skarn deposit at Arnastal is hosted by Late Cretaceous carbonate rocks comprised of limestone and the ...
Exergetic Analysis of Using Oxygenated Fuels in Spark-Ignition (SI) Engines
(Energy & Fuels (ACS Publications), 2009)
In this study, the use of the oxygenated fuels in spark-ignition (SI) engines has been investigated by means of exergy analysis. For this purpose, a two-zone quasi-dimensional thermodynamic cycle model was used. The cycle ...
Exergy Analysis of SI Engines
(International Journal of Exergy (Inderscience Publishers), 2008)
In this study, exergy (availability) analysis of a Spark Ignition (SI) engine has been performed theoretically during compression, combustion and expansion processes of the engine cycle. For this purpose, a thermodynamic-based ...
Effective atomic numbers and electron densities of CuGaSe2 semiconductor in the energy range 6-511 keV
(JOHN WILEY & SONS LTD, THE ATRIUM, SOUTHERN GATE, CHICHESTER PO19 8SQ, W SUSSEX, ENGLAND, 2008-09)
The effective atomic numbers and electron densities of the CuGaSe2 semiconductor were calculated at 29 different energies from 6.9 to 511.0 keV by using the measured mass attenuation coefficients. Also, the mass attenuation ...
The Geochemical and Sr-Nd isotopic Characteristics of Murgul (Artvin) Volcanics in the Eastern Black Sea Region (NE Turkey).
(Chemie der Erde/Geochemistry, 2014)
The studied volcanic rocks are footwall and hanging wall dacites from the Murgul mine and the surrounding area. Moreover, the hanging wall dacites contain enclaves. Footwall dacite contains biotite, whereas hanging wall ...
