In the four decades since the discovery that a discrete Bronze Age preceded the Iron Age in mainland Southeast Asia, much has been learned about the dating, technology, production, organization, and use of bronze metallurgy in the region, particularly in prehistoric Thailand. Although independent invention of copper smelting in Southeast Asia has not been considered likely by most regional arch...

This paper provides a high-level overview of some technology components currently considered for the evolution of LTE, referred to as LTE-Advanced. First, a brief overview of LTE and some of its technologies are given and then the IMT-Advanced requirements are discussed. One of the targets with the evolution of LTE is to reach or seven surpass these requirements. The technology components consi...

This paper addresses the performance targets and the technology components being studied by 3GPP for LTE-Advanced. The high level targets of LTE-Advanced are to meet or exceed the IMT-Advanced requirements set by ITU-R. A short history of the LTE standard is offered, along with a discussion of its standards and performance. The technology components considered for LTE-Advanced include extended ...

This paper reviews the optimization available transmission capability (ATC) of power systems using a device of FACTS named SSSC equipped with energy storage devices. So that, emplacement and improvement of parameters of SSSC will be illustrated. Thus, voltage magnitude constraints of network buses, line transient stability constraints and voltage breakdown constraints are considered. To help th...

This paper reports an efficient document compression technology suitable for on-line network transmission. It identifies the different segments – such as text, image, and background within a scanned document. Three distinct compression techniques are developed around the regular structure of Cellular Automata (CA) for the compression of text, image and background segments to achieve better comp...

High Tc superconducting (HTS) cables and their application to develop a DC power transmission system with substantial advantages have been studied. Technical analysis of the HTS DC electrical power transmission system behaviours have been carried out with the HTS DC cable technology employed and the system models built. Index Terms -High Temperature Superconductor (HTS), HTS Cable, DC Transmiss...

In this paper, we introduce the latest results of our two-dimensional communication project. The communication elements that touch the surface of a Two-Dimensional Signal Transmission (2DST) sheet establish the connection being supplied with the power by the 2DST sheet. The system allows free location of the element, and proximity (non-contact) connection is realized stably. The structure of 2D...

This paper discusses a distance learning system with reality transmission capability. Actual experience is crucial for education, in that much knowledge is obtained through the comparison of predictions with experimental results. Reality transmission capability allows real experiments to be performed in a distance learning system. Requirements for such a system are: (1) reality transmission cap...

This paper investigates transmission delay in technology-mediated interaction from a participant’s perspective. The approach chosen here contrasts with previous studies of delay: only what is seen, heard and done at one end (i.e., what is available on screen) is considered in the analysis. It is argued that participants themselves lack access to the other sides of their interactions as they unf...

As a new power transmission technology, magnetically coupled resonant wireless power transmission technology can achieve mid-range wireless power transmission with the advantage of high transmission efficiency. As known, the driving source has a significant impact on the overall performance of wireless power transmission system. With this consideration, a pulse-driven magnetically coupled reson...
