The parameters for this and four other well-known respiratory system models were estimated using impulse oscillometry data, obtained from both healthy and asthmatic children, in order to compare the modeling errors and the models' fidelity. Of these five models, the augmented RIC model ranked in the middle in terms of magnitude of modeling error for the given data, but other factors in its favor were determined. Hence it is the most reasonable model to use for further studies to improve the detection and diagnosis of respiratory diseases.","PeriodicalId":385396,"journal":{"name":"2006 IEEE Region 5 Conference","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114407758","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, there has been no appropriate metric to correctly evaluate the impact of a protocol strategy on battery-powered devices. This paper presents a method to evaluate minimum energy consumption of a protocol. In this paper, we apply a method, called energy complexity to separately compute minimum energy consumption due to transmissions, receptions, and protocol specific local computations for a protocol control-message transmission and data transmission strategies. This method can also be used to analytically experiment with protocols by changing their control-message and/or data transmission strategies. The usefulness of our method is demonstrated by analyzing two routing protocols for sensor networks.","PeriodicalId":385396,"journal":{"name":"2006 IEEE Region 5 Conference","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125428934","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 algorithm uses incremental updates for codewords and powers of individual users such that their corresponding signal-to-interference plus-noise ratios (SINR) at the receiver are maximized subject to specified power constraints. Updates are based on a steepest descent method which is a widely used digital signal processing technique, and which can be easily implemented in a wide range of hardware for communication systems. The proposed algorithm is analyzed and illustrated with numerical examples obtained from simulations.","PeriodicalId":385396,"journal":{"name":"2006 IEEE Region 5 Conference","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123108550","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}

TRABOL performs AIMD based congestion control such that transmission rate satisfies minimum and target rate requirements of the end user. Additionally, rate is adapted, while remaining friendly to the TCP cross traffic and efficiently using the bottleneck link bandwidth. This paper investigates the impact of different AIMD increase and decrease functions for congestion control on performance of the TRABOL protocol. A network emulator test bed is used for the performance evaluation, measuring the effectiveness of different AIMD rate control schemes in meeting bandwidth requirements of the end user, TCP-friendliness, bandwidth efficiency, and response time of the protocol.","PeriodicalId":385396,"journal":{"name":"2006 IEEE Region 5 Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130040716","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 images are subsequently transmitted in various forms over appropriate media. These images are always vulnerable to various forms of copyright attacks and ownership issues. This paper introduces a digital camera with built-in copyright protection and security mechanism for images produced by it. Since the proposal of the trustworthy digital camera by Friedman [1], significant research has been done in developing algorithms for watermarking and encryption with the aim of using them in digital cameras. However, only few of these efforts are involved with the architectural development of the entire digital camera. Incorporation of encryption and watermarking together in the digital camera will assist in protecting and authenticating image files. In this paper, we present an architecture and a hardware efficient FPGA based watermark module towards the development of the complete digital camera.","PeriodicalId":385396,"journal":{"name":"2006 IEEE Region 5 Conference","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121259461","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}
