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 ...
Genetic and Environmental of Milk Ability Traits in Holstein Friesian Cows
(Journal of Animal and Veterinary Advances, 2009)
The research was performed to determine the effect of non-genetic factors on milkability characteristics and to estimate genetic parameters and relationships among Milk Flow Rate (MFR), Milking Time (MT) and milk yields ...
Investigation of the Effect of Dual Ignition on the Exhaust Emissions of an SI Engine Operating on Different Conditions by Using Quasi-dimensional Thermodynamic Cycle Model
(Strojarstvo (Croatian Union of Mechanical Engineers and Naval Architects), 2009)
In the presented study, the effects of using dual-spark plug and variation of the spark plug location on the exhaust emissions of an SI engine operating in different conditions were investigated theoretically. A quasi-dimensional ...
Karadeniz’in Uluslararası Ticarete Açılması ve Trabzon
(Uluslararası Sosyal Araştırmalar Dergisi / The Journal of International Social Research, 2009-04)
Önemli bir coğrafi konumda bulunan Karadeniz, tarih boyunca kıyısında olan siyasi güçlerin ilgisini çekmiş ve bu denizde tarihin en eski dönemlerinden itibaren önemli ticari faaliyetler meydana gelmiştir. Her ne kadar bir ...
A New Method to Compensate for Counting Losses due to System Dead Time
(Nuclear Instruments and Methods in Physics Research A, 2009-05-21)
Determination of count losses and pile-up pulse effects in quantitative and qualitative analysis became a vital step in various analyses. Therefore, compensating for counting losses is of importance. These counting losses ...
Orman Amenajman Planlarının Simülasyon Tabanlı Planlanması: ETÇAPSimülasyon
(Kastamonu Üniversitesi, 2009)
Türkiye’de orman amenajman planlarının yapım süreci, çoğunlukla sezgisel yöntemler ve basit planlama teknikleri ile gerçekleştirilmektedir. Ancak, toplumun ormanlardan olan talebinin değişmesi ve artması, sürdürülebilir ...
