Broadcast and broadband communications have undoubt- edly become a part of today’s social life. Accessibility of content of interest to the audience at any place and at any time regardless of the type of content consumer device can have an effective contribution to the desire of the audience to use of the broadcast content. The HD and Ultra HD qualities, the desire for demand-driven application...

A well-known technique for broadcast program construction is the Broadcast Disks technique. However, in the Broadcast Disks approach there are some important disadvantages. For example some parts of the broadcast program remain empty during the construction procedure and the disk relative frequencies have to be selected very carefully. This paper gives a new approach of the broadcast program co...

Observing that it is impractical to use traditional methods to control concurrency in broadcast-based asymmetric communication environment, we introduce a concurrency control protocol designed for broadcast-based transaction processing called STUBcast (Server Timestamp and Update Broadcast Supported Concurrency). STUBcast supports two new correctness criteria proposed in this paper Single Seria...

A field micro-plot experiment using nitrogen isotope (15N) labeling was conducted to determine the effects of placement methods (broadcast and band) and N rates (60, 150 and 240 kg ha-1) on the fate of urea-15N in the wheat-soil system in Guangde County of Anhui Province, China. N fertilizer applied in bands increased grain yield by 15% compared with broadcast application. The N fertilizer appl...

Due to the importance of collective communications in scientific parallel applications, many strategies have been devised for optimizing collective communications for different kinds of parallel environments. Recently, there has been an increasing interest to evolve efficient broadcast algorithms for computational Grids. In this paper, we present application-oriented adaptive techniques that ta...

LTE broadcast is a communication standard which is expected to revolutionize the multimedia service provision in the future. The distinctive features of this standard such as increased service capacity, high spectral efficiency, and spectral adjustability have encouraged many companies to select this standard for the future generation broadcasting. In this paper, after a complete introduction o...

Because network-level reliable group communication protocols rely on IP multicast and have lack of reliability, this motivates the demand on application-level group communication. Epidemic-style protocols among these application-level approaches guarantee reasonably high reliability, provide good scalability and are easy to deploy. But, earlier versions of these protocols often rely on the assu...
