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, ... -
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 ... -
Mathematical analysis of spark ignition engine via the combination of the first and second laws of thermodynamics
(Proceedings of Royal Society A-Mathematical Physical & Engineering Sciences (Royal Society Publishing), 2008)This study aims at the theoretical exergetic evaluation of spark ignition engine operation. For this purpose, a two-zone quasi-dimensional cycle model was installed, not considering the complex calculation of fluid motions. ... -
Perturbation Based Stochastic Finite Element Analysis of the Structural Systems with Composite Sections under Earthquake Forces
(Steel and Composite Structures, 2008)This paper demonstrates an application of the perturbation based stochastic finite element method (SFEM) for predicting the performance of structural systems made of composite sections with random material properties. The ... -
A quantitative appraisal of earthquake hazard parameters computed from Gumbel I method for different regions in and around Turkey
(2008)The evaluation of the seismicity in 24 seismic regions, in which Turkey and adjacent areas divided, is carried out. For this purpose two methods are adopted. The first is the “whole process” which follows the Gutenberg and ... -
Properties of Aftershock Sequence of the 2003 Bingöl, MD=6.4, (Turkey) Earthquake
(Pure and Applied Geophysics, 2008)Aftershock sequences of the magnitude MW ¼6.4 Bingo¨l earthquake of 1 May, 2003 (Turkey) are studied to analyze the spatial and temporal variability of seismicity parameters of the b value of the frequencymagnitude ... -
Regional variation of the ? - upper bound magnitude of GIII distribution in and around Turkey: Tectonic implications for earthquake hazards
(Pure and Applied Geophysics, 2008)Complete data set of earthquakes in Turkey and the adjacent areas has been used in order to compute the x values in 24 seismic regions of Turkey. The parameter is obtained through Gumbel’s third asymptotic distribution of ... -
Seismicity assessment for the different regions in and around Turkey based on instrumental data: Gumbel first asymptotic distribution and Gutenberg-Richter cumulative frequency law
(Natural Hazards and Earth System Sciences, 2008)The evaluation of the seismicity in 24 seismic re gions, in which Turkey and adjacent areas divided, is car ried out. For this purpose two methods are adopted. The first is the “whole process” which follows the Gutenberg ... -
Source Rock Characteristics and Hydrocarbon Potential of Late Cretaceous Deposits in the Eastern Black Sea Region, NE Turkey
(Energy Sources, Part A, 2008)In this article, source rock characteristics and hydrocarbon potential of the late Cretaceous turbidite sequences in the eastern Black Sea region were investigated. The total average organic carbon (TOC) contents of sequences ... -
Rock Slope Stability and Excavatability Assessment of Rocks at the Kapikaya Dam Site, Eastern Turkey
(Engineering Geology, 2008)This paper describes the results of the engineering geological investigations and bearing capacity studies carried out at the proposed site of the rock fill Atasu Dam, to be constructed on basalts and pyroclastics. Rock ... -
The effects of the fiber contents on the mechanic properties of the adobes
(Construction and Building Materials, 2008-03)In this study, compression and tensile tests were conducted for five different adobe mixtures. The important part of this study consisted of uniaxial compressive tests done with natural fiber mixtures. Thus, the results ... -
