The business model needs to be flexible, adaptive, and integrated. Not only the system processes but also cultural and business strategies have to be coherent. This approach allows a company to handle any change in a much more adaptive way to compete in the market. In this paper, we proposed a step-by-step approach to define a new adaptive business model and based on our model, we present a scenario-based implementation as proof of concept.","PeriodicalId":371528,"journal":{"name":"Third International Conference on Information Technology and Applications (ICITA'05)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125624455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The statistical model of first-order Bragg lines and second order components of sea clutter is put forward. Then by using higher-order cumulative quantity's statistical verification of actually measured data, it is concluded that background noise before high-resolution conforms to normal distribution in ship-borne radar. The numerical domains distribution after high-resolution is determined by improved minimum entropy clutter characteristics recognition method based on rule AIC. This identification method has higher recognition rate. It is verified that background noise after high-resolution by pre-whitened-MUSIC conforms to lognormal distribution.","PeriodicalId":371528,"journal":{"name":"Third International Conference on Information Technology and Applications (ICITA'05)","volume":"723 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123850775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A new PAPR reduction method can be classified into method 1 and method 2. Method 1 reduces the correlation between the smallest sub-sequence and neighbor smallest subsequence. To consider the own correlation in detail, the method 1 reduces two cases of correlation between neighbor smallest sub-sequences and neighbor largest sub-sequences. Method 1 and method 2 has about 0.5-0.8 dB and 1-1.2 dB PAPR reduction effect respectively.

The NAND type flash memory, briefly denoted by NandFlash, is one of the more often-used storage devices. In terms of unit price, its cost is several dozen to hundred times more expensive than the traditional hard-disk (HD) since its storage space is limited. Therefore, to increase the storage space of NandFlash is great significance. In this paper, we improved the compression layer for NandFlash, which can be coordinated with the X-RL algorithm, to avoid overhead and reduce the degree of internal fragmentation in the compressed data pages. Hence, our proposed method can improve the compression rate. In the reading phase, we use the consecutive memory allocation method, which can reduce the superfluous time caused by non-consecutive access. Therefore, our architecture is meaningful and practical for embedded system applications.","PeriodicalId":371528,"journal":{"name":"Third International Conference on Information Technology and Applications (ICITA'05)","volume":"31 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134228126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, such specifications are inappropriate for some standards such as the standards for audio coders used in VoIP. For such standards, ITU-T commonly supplies a set of input test data with corresponding correct output results. In this paper, we focus on the G.729 audio-coder algorithm. We use a version of G.729 code that can produce the bit-exact desired output for the given set of input test data to show that there can still be errors in the code even though the output matches the output in the ITU-T specification. We demonstrate that the given test vectors are not comprehensive enough to detect some of the obscure errors that can exist in the software. Therefore, we cannot rely solely on the given test vectors to test and validate our code.","PeriodicalId":371528,"journal":{"name":"Third International Conference on Information Technology and Applications (ICITA'05)","volume":"254 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134075714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The problem was not solved until the privacy information retrieval (PIR) schemes were presented. A PIR scheme allows a user to retrieve a date item from online database while hiding the index of the data item from the database server. However, retrieving valuable information is another problem needs to be solved. Most transactions are completed by credit card through delivering its number and membership in the Internet to the server. Then the server knows the privacy of users. It becomes a challenge to private information retrieval (PIR) schemes considering the e-payment need. In this paper, we propose a new PIR scheme, which use a secure coprocessor (SC), with e-payment scheme for protecting the privacy of customers in querying valuable information. The scheme does not reveal personal information or buying information of customers in the Internet environment, it can really protect the customers' privacy. Comparing with previous PIR schemes, the scheme, combined with e-payment scheme in retrieving valuable information in special database, is more practical than previous PIR schemes in the Internet applications because of considering e-payment need","PeriodicalId":371528,"journal":{"name":"Third International Conference on Information Technology and Applications (ICITA'05)","volume":"52 27","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113990528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper we report on our experience with the development of the MacauMap application, a mobile digital map application that runs on PDAs and smart mobile phones.
