The RSS Reader is a software application that assist users easily to read and collect contents which are frequently changeable syndicated contents of RSS format that published on the web. This paper presents a formula software design based on RUP object-oriented design method for implementing the RSS Reader. We extract a use case based on requirements for implement of the RSS Reader and propose a domain concept model by. Using above artifacts, we extract event to generate between users and, the RSS Reader and logical architecture. So, we design classes and packages of the RSS Reader. As proposed a formula software design about the RSS Reader in early stage, it can make the RSS Reader with a variety of characters easily based on these.

This study matters the design and implementation of an intelligent information search engine that is based on the $R^2SS$(Reverse Really Simple Syndication). Apart from to the previous method, where the user inputs the RSS address that one intends and obtains limited RSS information, the user just types in the information that one appoints to acquire the RSS information of standard documents that the user is interested among several RSS addresses by a Reverse RSS(Really Simple Syndication) method, which is drawn by the automated RSS address collection server in realtime. Through the proposed $R^2SS$(Really Reverse Simple Syndication) based intelligent information search engine, time can be significantly saved along with obtaining information with good quality, furthermore, it has the effects of having a personal secretary.

Due to the recent tremendous growth of internet information, RSS, syndication technology provides internet users with a user-friendly information search. RSS enables you to automatically receive newly updated contents, so users do not need to constantly access web sites to obtain new information. This paper proposes the way of managing the web crawler, which collects the sites of RSS documents and helps the users efficiently use the RSS documents. And it also suggests the proper way of ranking the RSS documents based on the users' popularity. Users can efficiently search out the documents they need by using the proposed information searching methods.

A novel neighbor selection-based fingerprinting algorithm using matrix correlation (MC) for Wi-Fi localization is presented in this paper. Compared with classic fingerprinting algorithms that usually employ a single received signal strength (RSS) sample, the presented algorithm uses multiple on-line RSS samples in the form of a matrix and measures correlations between the on-line RSS matrix and RSS matrices in the radio-map. The algorithm makes efficient use of on-line RSS information and considers RSS variations of reference points (RPs) for localization, so it offers more accurate localization results than classic neighbor selection-based algorithms. Based on the MC algorithm, an error estimation method using artificial neural network is also presented to fuse available information that includes RSS samples and localization results computed by the MC algorithm and model the nonlinear relationship between the available information and localization errors. In the on-line phase, localization errors are estimated and then used to correct the localization results to reduce negative influences caused by a static radio-map and RP distribution. Experimental results demonstrate that the MC algorithm outperforms the other neighbor selection-based algorithms and the error estimation method can reduce the mean of localization errors by nearly half.

Recently, the most of website is supporting RSS with increasing the interest regarding web 2.0. RSS-reader is collecting the contents of RSS formats which are provided from the various web site and it is software application that assist users easily to getting the last update of area of interest without visiting a corresponding web site. In this paper, we developed RSS reader through Ajax which is an asynchronous method, JSP/Servlet which is a dynamic scripting language. We made them support both RSS format 1.0 and 2.0. Additionally developed fluid Ajax based menus, categories and functions of user-friendliness.

Few studies are found in literature on estimation of population quantiles using the method of ranked set sampling (RSS). The optimal RSS strategy is to select observations with at most two fixed rank order statistics from different ranked sets. In this paper, a near optimal unbalanced RSS model for estimating p^th(0 < p < 1) population quantile is proposed. Main advantage of this model is to use each rank order statistics and is distributionfree. The asymptotic relative efficiency (ARE) for balanced RSS, unbalanced optimal and proposed near-optimal methods are computed for different values of p. We also compared these AREs with respect to simple random sampling. The results show that proposed unbalanced RSS performs uniformly better than balanced RSS for all set sizes and is very close to the optimal RSS for large set sizes. For the practical utility, the near optimal unbalanced RSS is recommended for estimating the quantiles.

In the communication channel, the received signal is affected by many factors that can cause errors. These effects mean that received signal strength (RSS) based methods incur more errors in measuring distance and consequently result in low precision in the location detection process. As one of the approaches to overcome these problems, we propose using direction calibration to improve the performance of the RSS-based method for distance measurement, and sequentially a weighted least squares (WLS) method using reliability factors in conjunction with a conventional RSS weighting matrix is proposed to solve an over-determined localization process. The proposed scheme focuses on the features of the RSS method to improve the performance, and these effects are proved by the simulation results.

In this paper, we purpose requirement capturing for RSS reader that be able to aggregate and subscribe to a RSS format document and describing for analysis model. We execute requirement analysis and documentation by using analysis model which is adopted use case model. And the method of requirement analysis is based on Responsibility Driven Design. Analysis model that is not premised on special reader is able to use business model.

An advanced method of Relaxed Static Stability (RSS) is utilized for improving the aerodynamic performance of modem version supersonic jet fighter aircraft. The flight control system utilizes RSS criteria in both longitudinal and lateral-directional axes to achieve performance enhancements and improve stability. The T-50 advanced trainer employs the RSS concept in order to improve the aerodynamic performance and the flight control law in order to guarantee aircraft stability, The T-50 longitudinal control laws employ the dynamic inversion and proportional-plus-integral control method. This paper details the design process of developing longitudinal control laws for the RSS aircraft, utilizing the requirement of MIL-F-8785C. In addition, This paper addresses the analysis of aircraft characteristics such as damping, natural frequency, gain and phase margin about state variables for longitudinal inner loop feedback design.

This paper suggests prototype of dialog system combining VXML(VoiceXML) that is the W3C's standard XML format for specifying interactive voice dialogues between human and computer, and RSS(RDF Site Summary or Really Simple Syndication) that is representative technology of semantic web for syndication and subscription of updated web-contents. Merits of the proposed system are as following: 1) It is a new method that recognize spoken contents using ire and wireless telephone networks and then provide contents to user via STT(Speech-to-Text) and TTS(Text-to-Speech) instead of traditional method using web only. 2) It can apply advantage of RSS that subscription of updated contents is converted to VXML without modifying traditional method to provide RSS service, 3) In terms of users, it can reduce restriction on time-spate in search of contents that is provided by RSS because it uses ire and wireless telephone networks, not internet environment. 4) In terms of information provider, it does not need special component for syndication of the newest contents using speech recognition and synthesis technology. We implemented a news service system using VXML and RSS for performance evaluation of the proposed system. In experiment results, we estimated the response time and the speech recognition rate in subscription and search of actuality contents, and confirmed that the proposed system can provide contents those are provided using RSS Feed.
