  • We can categorize the network address allocation mechanism into two types. One is to assign a unique network address using the address allocation server and the other is to make a random address by itself and process the DAD(Duplicate Address Detection) procedure. In this paper we suggest a new address allocation mechanism based on the signal strength for the PLC-based home network. As the combined mechanism of two types this mechanism allocates a unique address for the new node from one of the existing nodes with the simple equation and with the priority based on the signal strength from the new node to the existing nodes. We can use this mechanism for the self-healing function when the packet from the source node may not be delivered to the destination node directly. We developed the simulator for our mechanism using the C# programming and verified the network address assigned uniquely based on the signal strength.

  • We propose a new address-while-display (AWD) driving method to obtain a high contrast ratio and a wide driving margin which is composed of a short ramp reset period, a sustain period and an address period as the basic unit. The short ramp reset (SRR) pulse made it possible to assure the wide operating voltage margin and minimize the background luminance by redistributing the wall charges between address and scan electrode. As a result, a high dark room contrast ratio of 10000 to 1 could be obtained with a wide operating voltage margin of 40V for stable address.

  • In this paper, we propose a vector quantization method which uses a dynamic address mapping based on exploring the high interblock correlation. In the proposed method, we reduce bit-rate by defining an address transform function, which maps a VQ address of an input block which will be encoded into a new address in the reordered codebook by using side match error. In one case that an original address can be transformed into a new transformed address which is lower than the threshold value, we encode the new address of the transformed convector, and in the other case we encode the address of the original convector which is not transformed. Experimental results indicate that the proposed scheme reduces the bit-rate by 45~50% compared with the ordi-nary VQ method forimage compression, at the same quality of the reconstructed image as that of the ordinary VQ system.

  • In order to achieve high efficiency and low cost, new high-speed addressing method is suggested. This can be achieved by reducing the address discharge delay time through the priming effect. This paper suggests a new ADR (Address During Reset) driving method which provides priming particles by using a separated driving method without adding auxiliary electrode or auxiliary discharge. The experimental results show an approximately loons reduction in the formative delay time of address discharge and a reduction in jitter of over 200ns. Also, due to enough time being available for reset, there was a reduction in light emitted during reset of about 29% which improved the dark contrast ratio considerably.

  • Present address system in korea was originally applied as a lot number system for the purpose of collecting taxes since 1910's, which has been changed irregularly by development of the urban areas. This unreasonable address system has disadvantaged the social welfare and the industrial structure, such as visiting, communication, delivery, sightseeing, marketing, transportation, etc. Therefore the new system, which would be rational and scientific, has been deeply demanded for the better services of spatial information and administrative efficiency of government. Korean government has launched the new address project as part of strengthening measures for national competitiveness since 1996. This paper would discuss the grant scheme of road name and building number in Cheongju city and evaluate the construction process of the new address management system.

  • The Internet has been growing at unprecedented rates. The problem of an address shortage could act as a barrier on this growth. In principle, a new Internet standard, IPv6 solves the problem of the address shortage because it has a very large address space. But IPv6 is not yet compatible with the IPv4 and during the IPv4-to-IPv6 transition period IPv4 address will continue to be in demand. Thus for quite some time, the problem of IP address shortage will persist. To solve the problem, we propose the mechanism of secure IP address trading. This mechanism is based on the Resource PKI (RPKI). The RPKI is the working item of IETF. This proposed mechanism maximizes the trust of IP address trading using RPKI.

  • New address electrode having separated dual electrode is suggested to reduce addressing time in ac PDP. Addressing characteristics of suggested electrode has been investigated in the test panel with high Xe partial pressure. It has been found that both the formative and jitter width of the suggested electrode is improved by 10 -20 % over the wide range of address voltage level compared with the conventional one. The dynamic margin of the panel also greatly improved. The key feature behind this type of structure is that it can extend the controllability of the wall charge distribution during the reset and address discharge without significant increase in capacitive load of address electrode.
