A modified Y -parameters approach is proposed to model the behavior of coupled oscillator arrays (COA’s). A coupling network with tunable coupling strength is proposed, which has a nearconstant input conductance, to ensure the oscillation condition under different attenuation levels. The parameters of oscillators and the coupling network are derived on the TSMC 0.18μm technology, and their Y pa...
A radiative transfer equation is used to model the diffuse multiple scattering of ultrasound in a medium containing discrete random scatterers. An assumption of uncorrelated phases allows one to write an equation of energy balance for the diffuse intensity. This ultrasonic radiative transfer equation contains single-scattering and propagation parameters that are calculated using the elastic wav...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
soil conservation service (scs) adjusted the kostiakovs infiltration model by adding a constant coefficient, for improvement of estimation. the improved model has three constant parameters, which are difficult to calculate. so scs has taken the third constant parameter as equal to 0.65-0.7 cm to simplify the estimation. this parameter varies in different soil and often outranges the scs estimat...
introduction: the use of low energy isotopes such as 103 pd in brachytherapy for the treatment of cancers such as prostate, eye, head, neck, breast and cervix is increasing. in this regard, different models of pd- 103 seeds have been designed and manufactured at the agricultural, medical and industrial research school (amirs) of atomic energy organization of iran. in this resear...
