On stability of a clamped-pinned pipe conveying fluid
In the past, stability of an undamped clamped-pinned pipe conveying fluid has been always considered numerically leading to controversial results. Païdoussis (2004) has shown that a numerical stability analysis of a clamped-pinned pipe requires exceptionally large number of vibration modes to obtain the correct dynamical behaviour. In this paper, analytical proof of stability of a clamped-pinne...
متن کاملDynamic and static properties of the randomly pinned planar flux array.
We report the results of large scale numerical studies of the dynamic and static properties of the random phase model of the randomly pinned flux lines confined in a plane. From the onset of nonlinear IV characteristics, we identify a vortex glass transition at the theoretically anticipated temperature. However, the vortex glass phase itself is much less glassy than expected. No signature of th...
متن کاملstatic versus dynamic assessment of l2 learners’ reading ability
dynamic assessment according to vygotskys sociocultural theory, states that instruction and assessment are interrelated. using static forms of assessment with second and foreign language students could do more harm than good. many teachers neglect to take account of the complexity involved in learning a second or foreign language and often wonder why learning of a language take so long. thi...

چکیده با توسعه شهر نشینی و دخل و تصرف غیر مجاز در حریم رودخانه ها خسارات زیادی به رودخانه و محیط زیست اطراف آن وارده می شود. در حال حاضر بر اساس آئین نامه اصلاح شده بستر و حریم رودخانه ها، حریم کمی رودخانه که بلافاصله پس از بستر قرار می گیرد از 1 تا20 متر از منتهی الیه طرفین بستر رودخانه تعیین، که مقدار دقیق آن در هر بازه از رودخانه مشخص نیست. در کشورهای دیگر روشهای متفاوتی من جمله: درصد ریسک...
15 صفحه اولHopes pinned on biofuel
California's boldness stemmed in part from the attitude of its governor, Arnold Schwarzenegger, a Republican who has been outspoken in his determination to combat global warming. " There are some issues in the world that are simply so compelling, whether in the United States or in the United Kingdom, that demand us to put aside our partisan differences and attack them head on, " Schwarzenegger ...
