Disease transmission The transmission model was individual-based and simulations were conducted in continuous time. The population was made up of people all of whom were in one of the disease states defined in Figure 1. The model progressed by simulating the time of the next infection and choosing the individual to which that infection occurred. After infection, disease progression within an in...

The techniques of progressive image transmission (PIT) divide image delivery into several phases. PIT’s main objective is to efficiently and effectively provide an approximate reconstruction of the original image in each phase. Therefore, this study proposes the Blocked Wavelet Progressive Image Transmission method (BWPIT) based on the wavelet transformation and the spatial similarity of pixels...

This paper describes two schemes that combine JPEG and Segmented Image Coding (SIC) for progressive image transmission. Compared to JPEG-based progressive transmission schemes, the new schemes produce reconstructed images of better quality during all the stages of transmission and never transmit more bits. Also, the computational complexity of the new schemes is lower than that of the SIC-only ...

Complex 3D building models, because of their huge data volume, almost always result in transmission congestion, which leads to poor user experience. To reduce the real-time pressure, a novel view-dependent progressive method was developed. With this method, only small amount transmitted is necessary achieve an acceptable rendering effect when viewpoint changes. The involves two stages. A prepro...

To circumvent the lack of knowledge of what measure is more suitable for optimization of the trade-off between image fidelity and coding rate, this paper shall introduce a novel mathematical methodology for rate control by organizing the progressive transmission in accordance with coherence constraints for avoiding forms of behavioral inconsistency. This methodology could be used within a progr...

Summery A fixed-packet optimal joint source channel coding scheme for transmission of progressive images over Rayleigh channels is proposed. A first order Markov model is used in rate allocation problem to concern channel temporal variations during image transmission. Also, introducing a modification on the used progressive coding scheme, the requirement for the immediate decoding termination u...
