The rating curve is the relationship between the water stage and the associated discharge in a givensection of a channel. In steady flow, this relationship usually has exponential type, whereas inunsteady it flow has a looped shape. Since direct developing of actual looped rating curve by usinghydrometric methods is merely possible, steady-state rating curve is commonly used as a downstreamboun...

The analysis in Chen, Kaya and Özer (2006) (henceforth, “the paper”) assumes that the manufacturer already has dual sales channels: a direct online channel, and an independent bricks-and-mortar retail channel. In this section, we study two single channel scenarios, and compare their results with the dual channel scenario results of the paper. First, we consider a manufacturer who sells only thr...

This paper concerns two-hop communication over relay-assisted Block fading channel. It is assumed there is not a direct link between the transmitter and the affiliated destination and the communication occurs in two hops through the use of a relay, where the amplify and forward (AF) strategy is employed at this node. In this case, in a Rayleigh block fading channel, the optimal weight function ...

In ecommerce, a product/service supplier with an Internet direct channel can sell through both its own direct channel and independent online retailers’ sites. The competition between the direct channel and the independent retailer’s channel has received significant research attention, however, little has been investigated on the impact of direct channel on the competition in wholesale market wh...

A multichannel reservation-based channel-access protocol is investigated in this paper. Under this protocol, one channel is used to exchange reservation messages and the remaining channels are used for information-bearing trajjic. The performance of this scheme is compared to that of a singlechannel reservation-based protocol. A simple contentionbased slotted-Aloha protocol is also considered. ...

in this study, the turbulent kinetic energy redistribution process is investigated. to this aim, the direct numerical simulation (dns) of incompressible flow of a newtonian fluid through a channel at a shear reynolds number of reτ = 180 is used to produce a flow data base. then, these data are statistically analyzed. the turbulent kinetic energy redistribution is studied using the pressure-stra...
