Background and objective: Developing fragility and vulnerability functions are important tools in seismic reliability assessment of buildings and are widely used in regional seismic risk studies. To date sufficient studies for developing analytical fragility functions for Iranian code-conforming buildings have not been carried out. Performing such studies are necessary to assess the adequacy of...
the purpose of the present study is to find out whether bilinguals of khuzestan-arab origin or monolinguals of iranian origin code-switch during learning or speaking english and which group is more susceptible to code-switch. to this end, the students of 24 classes from high schools and pre- university centers were screened out, and interviewed and their voices and code-switchings were recorded...
A new series of Z4-linear codes of high minimum Lee distance is given. It is derived from the Z4-linear representation of the Kerdock codes. The Gray image of the smallest of these codes is a nonlinear binary (114, 2, 56)-code, and in the second smallest case the Gray image is a nonlinear binary (1988, 2, 992)-code. Both codes have at least twice as many codewords as any linear binary code of e...
بررسی وجود و چندگانگی جوابهای معادلات دیفرانسیل به ویژه با شرایط مرزی اغلب بسی دشوار بوده و همراه با گام های ملالت آور می باشد بطوریکه همواره نیاز به پیش شرط هایی می باشد که معادلات دیفرانسیل با شرایط مرزی مورد نظر باید داشته باشد. بنابراین اثبات آنالیزی وجود و چندگانگی جوابهای مسائل مقدار مرزی غیر خطی اغلب غیر ممکن می باشد. روشهای تقریبی- تحلیلی یا روشهای عددی صرفاً برای بدست آوردن جواب موجود ...
A Global Navigation Satellite System (GNSS) receiver provides essentially two independent measurements of pseudorange through the estimation of code delay and carrier phase. Although the code delay estimate is an absolute (unambiguous) measurement its accuracy is hindered by noise; on the contrary, the phase estimate has, in general, better accuracy but is ambiguous. The Hatch filter has been u...
The linear and nonlinear physics of shear Alfvén waves are investigated using the 3D Braginskii fluid code BOUT++. The code has been verified against analytical calculations for the dispersion of kinetic and inertial Alfvén waves. Various mechanisms for forcing Alfvén waves in the code are explored, including introducing localized current sources similar to physical antennas used in experiments...
