Experimental analysis on the dynamic wake of an actuator disc undergoing transient loads

content analysis of l1 and l2 writing textbooks and the perception analysis of university professors on the influence of english writing expertise on the persian in an efl context

the importance of writing as a complex skill in applied linguistics has drawn the attention of many researchers to evaluate textbooks in order to help learners gain self-sufficiency and autonomy in the field of language use and communication. investigations have shown that developments in textbooks evaluation can promote the quality of pedagogies and consequently the learning. this study attemp...

Experimental Investigation of wake on an elliptic cylinder in the presence of tripping wire

In this research, the behavior and characteristics of the wake of flow in an elliptic cylinder with zero angle of attack in the presence of a tripping wire were investigated experimentally. For this purpose, the used an Aluminum cylinder with an elliptical cross section of the major and minor axis of 42.4 mm and 21.2 mm, respectively, and of the height of 390 mm. The cylinder model was examined...

Design of an Elastic Arthroplastic Disc Optimized under Different Loads

Introduction: Due to limitations of current treatments for degenerative disc disease, arthroplastic methods to repair the diseased disc have been proposed. The artificial disc is a mobile implant for degenerative disc replacement that attempts to lessen the degeneration of the adjacent elements following interbody fusion procedures. Because the success of artificial disc replacement depends on ...

An Integrated Loads Analysis Model for Wake Vortex Encounters

When a plane crosses the wake generated by a preceding aircraft, large dynamical loads in the order of the design loads may be induced. Loads analysis models for such wake vortex encounters need to consider aspects important for manoeuvre, as well as gust type responses. If the angle between the path and the trailing vortices is small, the encounter is manoeuvre like due to large induced roll m...
