A communication system based on the joint source-channel coding principle is proposed where a fixed-rate source encoder using neither a codebook nor an entropy encoder is exploited to avoid the error propagation effect and thus gain in system robustness. An explicit expression of the mean square error (MSE) distortion of the system for a uniform source is derived. Based on the MSE distortion, the optimal design of the communication system under the total transmission rate constraint is formulated as a mixed integer nonlinear optimization problem. We provide an algorithm to achieve the optimal solution via a convex optimization solver. The numerical result shows that the overall performance of the proposed system is close to the performance of the entropy coding scalar quantizer (ECSQ) system established by A. Gyorgy and T. Linder [1] for almost all rate regions.

A dynamic two-dimensional problem has been considered to investigate the disturbance due to mechanical and thermal sources in a homogeneous thermal conducting poroelastic medium. Laplace and Fourier transform technique is used to solve the problem. The application of the concentrated and distributedsources are taken to illustrate the utility of the approach. The transformed components of displacement, stress, pore pressure and temperature change are obtained and inverted numerically by using numerical inversion technique. The effect of porosity on the resulting quantities is presented graphically. Some special cases of interest are also deduced.
