This paper presents a brief history of the hydraulic jump and literature review on jumps’ experimental numerical studies. Leonardo da Vinci noticed this phenomenon early on, but it was only later studied by Bidone in 1820. Since beginning 20th century, has received lot attention following development energy dissipater designs stilling basins. The late 1920s 1930s saw many studies researching su...

Neurodegenerative diseases (ND) are characterized by the progressive loss of specific neuronal populations with consequent deterioration of brain's function. While some ND have monogenic causes, the vast majority is sporadic. Accordingly, etiology varies greatly between these conditions; the pathogenesis, however, shares important common traits. Trophic deprivation, oxidative stress, accumulati...

دشت شیراز با توجه به شکل خاص خود پتانسیل بالایی از نظر آلودگی دارد. پس از تقسیم بندی منابع آلاینده به 6 گروه مختلف، در هر گروه منابع ناشی از آلاینده ها شناسایی گردید. سپس بر اساس استانداردهای موجود، یک برنامه پایش تدوین شد.در نهایت با استفاده از مدل basins برنامه پایش پیشنهادی اصلاح و بهینه گردید.

Fish migration is essential to maintain healthy aquatic ecosystems, but hydraulic structures across rivers have impeded natural fish worldwide. While efforts been made allow pass some structures, there limited understanding of hydrodynamic effects that cause injury in different systems, such as spillways and stilling basins well hydropower systems. This study reviewed available literature on th...

In this study accuracy of the ANFIS and ANFIS-PSO models to estimate hydraulic jump characteristics including sequence depth ratio, the jump length, the roller length ratio, and relative energy loss was evaluated in stilling basin versus laboratory results. The mentioned characteristics were measured in the stilling basin with a rectangular cross-section with four different adverse slopes, four...
