The transmission distance of transmission lines is long, the line affected by the diversity of climate and topography of the corridors of transmission lines, differences in regional geological structu...
The Structural Engineering Institute (SEI) was established on October 1, 1996 in order to serve the unique needs of the structural engineering community while influencing change on the broader issues ...
Multiplexing, the ability to send multiple signals through a single channel, is a fundamental feature of any voice or data communication system. An international research team has demonstrated for the...

This paper presents a multi-way tree based multi-scale line structure for progressive transmission of vector data. By topological restraints, the structure maintains the consistent topologicalrelation...
Since the moment Google Earth launched by Google company, the subject of geographic information system (GIS in short) has made great progress. While, the traditional two-dimensional and three-dimensio...
This paper presents a method of progressive transmission of vector data on the web based on the Changes Accumulation Model. The model considers the spatial representation from one scale to another sca...
The experience acquired from more than ten years of operation of an Antarctic geomagnetic observatory is described along with the development of data transmission facilities. The observatory was deplo...
Adapting to a time-varying channel to maximize the average information rate for a given power constraint is a well-understood problem. Important studies (e.g., [I], [Z], [3]) have developed optimal ra...
We investigate the minimum-energy packet scheduling problem for the multiaccess channel with K transmitters and a single receiver, assuming that packets arrive at each transmitter’s buffer at arbitrar...
We then devise a lazy online algorithm that varies transmission times according to backlog and show that it is more energy efficient than a deterministic schedule that guarantees stability for t...
This paper investigates the problem of energy-efficient transmission of data packets in a wireless network by jointly adapting to backlog and channel condition. Specifically, we consider minimum-energ...
The paper considers the problem of minimizing the energy used to transmit packets over a wireless link via lazy schedules that judiciously vary packet transmission times. The problem is motivated by t...
