In this paper, we propose an effective path virtualization system using Fountain code that provides the highest possible data rate with satisfactory delay and block loss rate constraints to enhance video quality. Basically, Fountain code and video codec H. 264 are tightly coupled to efficiently use the path diversity over existing heterogeneous wireless networks. Finally, the proposed system is...

In this paper, we consider the existence of multiple solutions for the following p(x)-Laplacian equations with critical Sobolev growth conditions { −div(|∇u|p(x)−2 ∇u) + |u|p(x)−2 u = f(x, u) in Ω, u = 0 on ∂Ω. We show the existence of infinitely many pairs of solutions by applying the Fountain Theorem and the Dual Fountain Theorem respectively. We also present a variant of the concentration-co...

Procedural modeling is a method that determines production rules and allows for developing effective structural design in architecture. Fountain (Shadirvan) an important component of Turkish architecture having symmetrical structure distinctive elements makes fountains suitable procedural modeling. In this study, we propose to different fountain models similar ones exist We specify the paramete...

In contrast to the relatively high attention paid to the structural heterogeneity of striatal dopamine (DA) innervation, little attention has been focused on the possible striatal heterogeneity for release and uptake of DA. By using amperometric methods, we found striatal regions showing a DA decrease during the medial forebrain bundle stimulation (drain areas) near to other zones that showed a...

Providing efficient and reliable data transport is a challenging problem for a variety of emerging applications which require reliable data packet delivery in wireless networks. In this paper, we propose to incorporate fountain codes at transport layer in the notion of cooperative relay communications to provide reliability and robustness for data transmission in wireless networks. Our basic id...

The application of intense ultrasound to a liquid-gas interface results in the formation of an ultrasonic fountain and generates both mist and vapor from the liquid. Here, the composition of the vapor and aerosol above an ultrasonic fountain is determined as a function of irradiation time and compared with the results of sparging for five different solutions. The experimental apparatus for dete...

Cooperative communications, where parallel relays forward information to a destination node, can effectively improve the latency in ad hoc networks. In practice, the performance of data transmission often compromises with the variation of channel coefficient and the mobility of network nodes. The conventional fixed rate cooperative relaying cannot make the outage probability reach zero without ...
