The idea of writing such a technical brief goes back to our days in Quantum corporation, when we were studying efficient coding strategies for cloud storage applications. Having had a thorough review of the literature, I decided to write this document in order to establish a common base ground on which the majority of the relevant research can be analyzed and compared. As far as I am concerned,...

—In the past few years, joint network-channel coding (JNCC) has drawn significant attention for reliable data communication in wireless network. However, it appears that fixed-rate channel coding is ineffective to make the outage probability to zero without having precise channel state information at the transmitter. To enhance the link robustness and the system throughput, this paper presents...

A new universal noise-robust lossless compression algorithm based on a decremental redundancy approach with Fountain codes is proposed. The binary entropy code is harnessed to compress complex sources with the addition of a preprocessing system in this paper. Both the whole binary entropy range compression performance and the noise-robustness of an existing incremental redundancy Fountain code ...

This paper proposes a fountain-code-based multi-path transport protocol, called heterogeneous multi-path transport protocol (HMTP), and evaluates its performance. HMTP improves the throughput performance and path utilization of multi-homing wireless erasure networks. It solves the receive buffer blocking problem and eliminates the need for retransmissions and in-order packet delivery, both of w...

Abstract To reduce or completely remove the viewing angle dependence of liquid crystal (LC) displays and devices, we have recently introduced a new electrode structure for LC displays. This has openings (holes) in pixel (PixE) generating fringe electric field with azimuthal degenerated distribution lines around each hole, resembling fountain. Such is promoting azimuthally switching molecules th...

background: due to the lack of proper rail road and air transportation, most commutes in iran are carried out by buses. in most cases, the water in the busses is used for passengers for drinking usage. although this kind of water source has provided convince for the travelers, it could be a great risk in disease outbreak. the aim of this study is to determine the water quality in commuting buse...

Code dissemination in wireless ad hoc network is an important aspect of network deployment. Once deployed, the network nodes may still need software updates to keep up with the changing application demand, thus making wireless broadcast an important aspect of any wireless network deployment. We present FBcast, a new broadcast protocol based on the principles of modern erasure codes. FBcast prov...

background and purpose: school, as a reliable place in educating students, has an important role in training. the aim of this study was the assessment of environmental health of primary schools in norabad mamasani city of fars province. materials and methods: in this analytical-descriptive and cross-sectional study, all of 26 primary schools in norabad mamasani city were surveyed by using censu...
