[1] A new method has been developed that models the changes a wave-formed rippled sediment bed undergoes as it is actively evolving between two given equilibrium states due to a change in surface wave conditions. The transient analysis of rippled beds has received very little attention within the literature. Dynamic changes within ripple parameters have implications for the estimation of flow d...

We are concerned with size-structured population models of general type with the growth rate depending on the individual’s size and time. In [3], the local existence and uniqueness of the solution have been investigated. In this paper, we discuss the positivity and global existence of the solution as well as L∞ solutions. As is explained in [3], the model in our mind is the population dynamics ...

inflation has always been an economic problem and different solutions have been proposed to control it. although it is said that “higher output lowers inflation rate” but it is true when other factors are constant. this study searches the answer to the following question: “what is the effect of inflation rate and output in a case that inflation rate and output growth has a volatility trend?” to...
