The primary appeal associated with employing robots is that they tend to capture the attention of the target audience and thereby facilitate the learning process. While there are numerous robotic kits on the market today, few can be used to teach both high-level concepts in computer science and engineering as well as low-level concepts in a K-12 environment and those that are capable, are more expensive. In this paper we propose an affordable setup of a basic software and hardware framework to accomplish this interaction. Specifically, the overall system architecture, low-cost robot, Web service and mobile device software will be the topics of interest in this paper.","PeriodicalId":319164,"journal":{"name":"2004 IEEE Electro/Information Technology Conference","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127100409","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 production and distribution of multimedia data in digital format, raises the intellectual property rights (IPR) protection problem, since the digital data can be easily copied without quality degradation. With digital watermarking, information containing origin, status, and/or destination of the data, can be imperceptibly and robustly embedded in the host data. As a consequence, the watermark should survive against unintentional attacks such as common image processing and/or hostile intentional attacks which may occur to destroy the watermark. This paper describes an efficient watermarking algorithm using spatial domain technique. Descriptions of watermark insertion-verification 'C code and a real-time implementation of the insertion mechanism, running on TITMS320C6711 DSP are given. The paper is organized as follows: after this short introduction, the algorithm steps are presented, followed by special consideration regarding the real-time implementation on TI's TMS320C6711 DSP. Applications of watermarking process in real-time are also described.","PeriodicalId":319164,"journal":{"name":"2004 IEEE Electro/Information Technology Conference","volume":"206 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115569234","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 two 3G systems are wideband-code division multiple access (W-CDMA) and code division multiple access2000 (CDMA2000). These two systems have different signaling characteristics and are not interoperable, but both use code division multiple access (CDMA). Due to the inherent nature of CDMA, it is feasible for W-CDMA and CDMA2000 to coexist with each other albeit with a predictable degradation in performance. This paper describes the signaling characteristics of the two 3G systems that prevent signal interoperability between them. The paper then shows that W-CDMA and CDMA2000 can coexist, and quantifies the degradation in the capacity for each system as users of the other system are added within the shared spectrum. The capacity is determined both analytically and using matrix laboratory (MATLAB) based simulations.","PeriodicalId":319164,"journal":{"name":"2004 IEEE Electro/Information Technology Conference","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114540457","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}

This class of nonlinearities is chosen based on the fact that they may lead to chaotic behavior for possible later use on chaotic communications applications. An unbiased state estimator is proposed having a quadratic structure and a parametric optimization problem is solved to obtain the minimum error variance. Another unbiased suboptimal estimator having a much simpler structure is proposed to provide an error performance bound on the minimum variance estimator. The performance results of these two minimum variance estimators are shown to be clearly superior to those of the extended Kalman filter for some scalar chaotic systems.","PeriodicalId":319164,"journal":{"name":"2004 IEEE Electro/Information Technology Conference","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132547277","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 long list of metrics exists in the IT industry. Majority of these metrics (e.g. defect removal efficiency), when applied well, have proven to provide useful historical perspective of the software quality. The proper interpretation of these metrics is typically time dependant, requiring meeting of a certain milestone. This creates a constraining effect on the software engineer's ability to take actions on a cost-effective and ongoing basis on a project. In this paper, we introduce a set of time- independent dimensions to a well-established quality metric. We refer to the metrics, analyzed along the time-independent dimensions, as comparative metrics. Upon slicing and dicing the data along the time- independent dimensions, software engineers can draw logical conclusions and therefore take corrective actions on an ongoing basis. The net result is improved software quality.","PeriodicalId":319164,"journal":{"name":"2004 IEEE Electro/Information Technology Conference","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132162800","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}
