Mathematical models of a hydraulic shock

Mathematical Modelling of a Hydraulic Accumulator for Hydraulic Hybrid Drives

New classes of Extereme Shock Models

 In industry or nature, ‎there are systems subjected to a secuence of shocks ocurring randomly in time‎. ‎these shocks are causing aging or failure of system‎. ‎According to the type of shocks‎, ‎shock models divided in two major groups‎, ‎Extreme Shock Models and Cumulative Shock Models‎. ‎In the extreme shock models just impact of last shock named fatal shock would be studied and in the cumul...

validation of a revised logical-mathematical intelligence scale and exploring its relationship with english language proficiency

نظریه هوش چندگانه قسمتهای متفاوت هوش بشری را مورد بررسی قرار می دهد که با شناخت آن شخص به درک بهتری از توانایی های خود میرسد و در نتیجه سعی در استفاده از آن جهت یادگیری بهتر میکند. همچنین با شناخت استعداد دانش آموزان، فرایند یادگیری بهتر میشود. هدف از انجام دادن این تحقیق بررسی رابطه بین هوش ریاضی و استعداد یادگیری زبان انگلیسی میباشد. برای انجام این تحقیق از پرسشنامه هوش ریاضی که توسط شیرر در ...

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...

a study on thermodynamic models for simulation of 1,3 butadiene purification columns

attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
