the relationship between eq, iq and test format: a study on test fairness
the major aim of this study was to investigate the relationship between iq, eq and test format in the light of test fairness considerations. this study took this relationship into account to see if people with different eq and iq performed differently on different test formats. to this end, 90 advanced learners of english form college of ferdowsi university of mashhad were chosen. they were ask...
15 صفحه اولDetermination of Material Strengths by Hydraulic Bulge Test
The hydraulic bulge test (HBT) method is proposed to determine material tensile strengths. The basic idea of HBT is similar to the small punch test (SPT), but inspired by the manufacturing process of rupture discs-high-pressure hydraulic oil is used instead of punch to cause specimen deformation. Compared with SPT method, the HBT method can avoid some of influence factors, such as punch dimensi...
متن کاملCharacterization of PEEK biomaterials using the small punch test.
The small punch test is widely used to characterize the ductility and fracture resistance in metals and ceramics, when only a small volume of material is available. This study was conducted to investigate the suitability of the small punch test for characterizing polyetheretherketone (PEEK) polymeric biomaterials for changes in material grade, crystallinity, and molding process. The small punch...
متن کاملCorrelation Factor Study of Small Punch Creep Test and Its Life Prediction
A small punch test is one of the innovative methods that can be used to evaluate the properties of a material without destructive harm to the in-service component. Conventionally identifying material properties by a uniaxial test is widely applied to engineering. How the properties obtained from a small punch test can be applied with the same utility has been a goal. In 2006, European Code of P...

چکیده مهارت شنیداری برای مدتهای طولانی در آموزش ، تحقیق و ارزیابی مورد غفلت قرار گرفته است. اگرچه در سالهای اخیر به خاطر اهمیت قابل ملاحظه این توانائیها در آموزش و آزمون زبان ، توجه بیشتری به توانائیهای شنیداری شده است. هم چنانکه درک شنیداری در آموزش و ارزیابی زبان دوم اهمیت فزاینده ای می یابد محققین سعی نموده اند تا ماهیت مهارتهای مستتر در مهارت شنیداری را مورد بررسی و مطالعه قرار دهند. هدف ...
