A thermodynamic approach to compare the performance of rhombic-drive and crank-drive mechanisms for a beta-type Stirling engine
(Elsevier Ltd, 2016)In this study, the effect of rhombic drive and crank drive mechanisms on the performance of a beta-type Stirling engine was investigated by nodal analysis. Kinematic and thermodynamic relations for both drive mechanisms ... -
Combustion and performance characteristics of an HCCI engine utilizing trapped residual gas via reduced valve lift
(Elsevier Ltd, 2016)In this study, the effects of residual gas fraction (RGF) on homogeneous charged compression ignition (HCCI) combustion were investigated experimentally. Experiments were performed at different lambda values and constant ... -
Rollover crashworthiness analysis of a railroad passenger car
(2013)Rollover of railroad passenger cars is one of the most serious accidents having high rates of injuries and fatalities. Therefore, the railroad passenger car structures should satisfy the rollover crashworthiness requirements ... -
Energy absorption of circular aluminium tubes with functionally graded thickness under axial impact loading
(Taylor and Francis Ltd., 2015)The main objective of this study is to investigate the effects of thickness-gradient patterns on energy absorption characteristics of aluminium-based circular tubes under axial impact loading. Functionally graded thickness ... -
A comparative study on crashworthiness of thin-walled tubes with functionally graded thickness under oblique impact loadings
(Taylor and Francis Ltd., 2019)The main objective of this study is to investigate the effects of functionally graded thickness (FGT) patterns and cross-sectional shapes (i.e. circular, square and hexagonal) on crashworthiness performance of thin-walled ... -
Genome response of model invertebrates and vertebrates species to stress agents in the environment
(2010)The genome response of model invertebrate and vertebrate species to stress agent in the environment was studied. The both group of species were collected from contaminated water stations along Marisa (Kemera) and Chaya ... -
An interactive gis-based software for dynamic monitoring of rivers
(Scibulcom Ltd., 2014)Water quality research and development attempts have been the most valuable resources in the sense of model calibration and verification techniques. Due to the fact that current degree of pollution in rivers and importance ... -
A kind of energy storage technology: Metal organic frameworks
(2012)Abstract- For last fifteen years energy has been transferred by using electricity. As an energy carrier electricity has some disadvantages like its wire need for transportation and its being non-storable for large amounts. ... -

(2012)Objective: The aim of this study was to determine the effect of different palatal vault shapes on the dimensional stability of a glass fiber reinforced heat polymerized acrylic resin denture base material. Methods: Three ... -
Production of Ti-Fe based MgAl2O4 composite material by pressureless infiltration method
(Gazi University, 2015)In spite of their high temperature and corrosion resistance, ceramics show a brittle nature under applied loads and this limits their usage areas. In order to compensate the weakness of ceramics with metals, which have ... -
Solid phase synthesis of anhydrous zinc borate from zinc and boron oxide and utilization as a flame retardant in dye and textile
(Gazi University, 2014)Durability of materials against flame and stability at high temperatures are very important in order to increase the field of use. Non-flammability is not the only requirement; these materials should not have toxic gas ... -
Evaluation of environmental wastes in building material
