Surface topography of jet shock cells in a hydraulic analogy

The photograph in Fig. 1 (top) shows text visualized through free surface flow, which serves as a hydraulic analogy of an underexpanded two-dimensional jet at Froude number 1.35 [analogous to Mach number (Buchanan et al. 2007)]. The text is illuminated by a halogen lamp from below a water table and used as a Fig. 1 Photograph (top) of the analogy to shock cells downstream of a nozzle at Mach nu...

the effect of genre-based teaching on reading comprehension of literary texts

تحقیق حاضر به بررسی کاربرد روش ژانر-محور را در محیط آموزش زبان عمومی می پردازد.روش ژانر-محور به زبان آموزان کمک میکند که در زمینه خوانش پیشرفت کنند. بعضی از محققین معتقد اند که روش تدریس ژانر-محور به تدریج به زبان آموزان کمک می کند تا در درک ژانر های مختلف مهارت یابند (هایلند 2004).همچنین امروزه توجه روز افزونی به اهمیت استفاده از ادبیات در برنامه آموزشی زبان انگلیسی (esl/efl ) شده است. زمانی ک...

On Model-based Control of Hydraulic Actuators

Electrohydraulic servosystems exhibit highly nonlinear behavior to the effect that classical linear controllers, e.g., PD, usually achieve a limited performance. Load static and dynamic parameters variations are also contributing to the limitation of their position and force tracking performance. This paper presents a modelbased controller applied to a fully detailed model of an electrohydrauli...
