RAIM techniques based on TLS have rarely been addressed because TLS requires a great number of computations. In this paper, the particular form of the observation matrix H, is exploited so as to develop a new TLS-based sequential algorithm to identify an errant satellite. The algorithm allows us to enjoy the advantages of TLS with less computational burden. The proposed algorithm is verified through a numerical simulation.

현재 중국의 인터넷 종합 포털 사이트 시장은 서비스 면에서 동질화 경쟁이 매우 치열해 새로운 수익모델을 개발해야 할 필요성이 증가하고 있다. 포털 시장은 향후 세분화 추세를 보일 것으로 추정되긴 하나, 구체적인 경쟁구도는 아직 불분명한 상태이다. 본 보고서에서는 2005년 상반기까지 나타난 중국 인터넷 시장의 사용현황 및 포털 시장분석을 통하여 중국 인터넷에 나타난 주요 변화와 주요 포털 의 경쟁력 분석 및 중국 인터넷 포털 시장에 대한 객관적인 평가를 시도해 보고자 한다.

Conservation is the optimum sustained use of natural resources; therefore, cave conservation must provide not only for the protection of the character, decoration and biota of caves, but also for the means whereby people might enjoy and understand the caves that are their heritage. A cave is a natural subterranean cavity into which a man can enter to a point where daylight cannot be seen. Caves are not only interesting physical entities that provide distinctive sensory and perceptual experiences and invoke a variety of responses, but they also provide unique opportunities for scientific study. Speleology is the study of caves, and in New Zealand it attracts workers from many disciplines of the universities and government research establishments.(omitted)

Since thousands of years ago, silk has been treasured as much as diamond and pearl. It is because silk has its unique aroma which no man made fiber can equal to. People in any part of the world can not enjoy a really rich living or a bright frame of mind without wearing silk. This means the silk is only silk. Mystery of silk and mysterious quality of silk come from the fact that it is a protein fiber produced by the living insect, namely, the silkworm. (omitted)

In teaching statistics in the secondary school, most math teachers do it and students enjoy it well before 11th grade. But, both of teachers and students feel statistics hard at 11th grade, which has been contained permutations, combinations, random variables, probability distributions, hypotheses and tests for normal distribution. In this study, we explore the efficient teaching methods of statistics for math teachers and also find many students enjoying it.

Ad(advertisement) is a gateway that makes the public recognize enterprises, and a tool that can maximize customers' interest. How this kind of Ad is delivered to consumers governs an enterprise's image or goods' reliability. That's why enterprises spend much money in advertising their products in various ways such as TV Ad, newspaper Ad, magazine Ad, placards and so on Accordingly, this study intends to look at Game Ad among a number of Ads, which enables game users to enjoy games at low expense and at the same time makes them naturally recognize enterprises images or product PR.

Gradient enhanced theories of crystal plasticity enjoy great research interest. The focus of this work is on thermodynamically consistent modeling of grain size dependent hardening effects. In this contribution, we develop a model framework for damage coupled to gradient enhanced crystal thermoplasticity. The damage initiation is directly linked to the accumulated plastic slip. The theoretical setting is that of finite strains. Numerical results on single-crystalline metal showing the development of damage conclude the paper.

This study investigates the literatures of leisure function and resource of the elderly to consider deeply the meaning of their leisure. In conclusion, this study presents the leisure of the elderly has both of positive and negative functions individually, socially and economically and they have the resources of individual, human and social as the usable resources for leisure but each of resources has disturbing restrictions. On the actual condition of elderly's leisure activity, they enjoy negatively like a watching TV and the using rate of leisure facilities is lower than other age groups.
