Determine the source term of a two-dimensional heat equation
Let be a two-dimensional heat conduction body. We consider the
problem of determining the heat source with
be given inexactly and be unknown. The problem is nonlinear and ill-posed.
By a specific form of Fourier transforms, we shall show that the heat source is
determined uniquely by the minimum boundary condition and the temperature
distribution in at the initial time and at the final time .
Using the methods of Tikhonov's regularization and truncated integration, we
construct the regularized solutions. Numerical part is given.Comment: 18 page
Determination of the body force of a two-dimensional isotropic elastic body
Let represent a twodimensional isotropic elastic body. We
consider the problem of determining the body force whose form

regularization and truncated integration, we construct a regularized solution
from the data given inexactly and derive the explicitly error estimate.

Determine the spacial term of a two-dimensional heat source
We consider the problem of determining a pair of functions satisfying
the heat equation , where and the function is given. The problem is
ill-posed. Under a slight condition on , we show that the solution is
determined uniquely from some boundary data and the initial temperature. Using
the interpolation method and the truncated Fourier series, we construct a
regularized solution of the source term from non-smooth data. The error
estimate and numerical experiments are given.Comment: 18 page
A Hybrid of Adaptation and Dynamic Routing based on SDN for Improving QoE in HTTP Adaptive VBR Video Streaming
Recently, HTTP Adaptive Streaming HAS has received significant attention from
both industry and academia based on its ability to enhancing media streaming
services over the Internet. Recent research solutions that have tried to
improve HAS by adaptation at the client side only may not be completely
effective without interacting with routing decisions in the upper layers. In
this paper, we address the aforementioned issue by proposing a dynamic
bandwidth allocation and management architecture for streaming video flows to
improve users satisfaction. We also introduce an initial cross layer hybrid
method that combines quality adaptation of variable bitrate video streaming
over the HTTP protocol at the client side and SDN based dynamical routing. This
scheme is enabled by the Software Defined Networking architecture that is now
being considered as an emerging paradigm that disassociates the forwarding
process from the routing process. SDN brings flexibility and the ability to
flexibly change routing solutions, in turn resulting in dynamically improving
the services provided in the application layer. Our experimental results show
that the proposed solution offers significantly higher overall bitrates as well
as smoother viewing experience than existing methods.Comment: 14 pages, 17 figures, IJCSNS International Journal of Computer
