Effects of Methanol Addition to Gasoline on the Performance and Fuel Cost of a Spark Ignition Engine
(Energy & Fuels (ACS Publishers), 2008)
This study is concerned with investigating experimentally the effects of methanol blending to base gasoline on the performance and fuel cost of a spark ignition (SI) engine. The fuel blends were prepared by blending 5, 10, ...
Effects of Methyl tert-Butyl Ether Addition to Base Gasoline on the Performance and CO Emissions of a SI Engine
(Energy & Fuels (ACS Publications), 2008)
This study aims at investigating experimentally the effects of methyl tert-butyl ether (MTBE)-gasoline blends on the performance and CO emissions of a spark ignition engine. The blends are prepared by blending 5, 10, 15, ...
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 ...
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 ...
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 ...
Fizik Öğretmenleri için Üniversite Destekli bir Hizmet içi Eğitim Model Önerisi
(The Turkish Online Journal of Educational Technology (TOJET), 2004-01)
Eğitim literatürümüzde hizmet içi eğitimle ilgili yürütülen bir çok araştırmanın sonuçları MEB tarafından fen ve fizik öğretmenleri için yeterli sayıda ve etkili hizmet içi eğitim kurslarının düzenlenmediğini, ayrıca merkezi ...
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 ...
Küreselleşme Sürecinde Yerelleşme ve Yerel Demokrasi
(Akademik Bakış, 2007-01)
Bilgi Çağı” olarak da adlandırılan içinde bulunduğumuz zamanda, en çok tartışılan konulardan biri “küreselleşme” diğeri ise “yerelleşme”dir. Küreselleşme süreciyle birlikte dünyada büyük bir değişim süreci başlamıştır. ...
