The inverse Fourier transform is defined by the integral Fourier formula which is referred to as the correlation of the function (signal) with cosine waveforms of various frequencies. This is a direct way to perform the time-frequency analysis of signals. The Fourier transform is described as the sum of wavelet-like transforms with the cosine analyzing function of one period. Properties of such transforms, including the inverse formula of reconstruction of the signal by the described wavelet-like transforms are described. Examples of application of such transforms to detect the exact location of a high-frequency signal are given.","PeriodicalId":385396,"journal":{"name":"2006 IEEE Region 5 Conference","volume":"103 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":"128232478","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}

Thus, they often lack supports for other important practical considerations commonly used in software development (e.g., ease of software modification and maintenance, and portability of resulting models). This paper studies principles for the development of data mining systems from software engineering perspectives. In particular, we propose a framework architecture that provides four desirable characteristics: extensibility, modularity, flexibility and interoperabity. The architecture utilizes a design pattern called Pipes and Filters together with data replication to provide loosely coupled structures for the systems. It also facilitates interoperability and reusability of the resulting predictive models obtained from the mining process by means of appropriate interface mechanisms. The proposed architecture promises important advantages that can enhance the usability of data mining systems.","PeriodicalId":385396,"journal":{"name":"2006 IEEE Region 5 Conference","volume":"60 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":"133956443","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}

Subramanian","doi":"10.1109/TPSD.2006.5507461","DOIUrl":"https://doi.org/10.1109/TPSD.2006.5507461","url":null,"abstract":"Often times we may find ourselves in a situation where we are miles away and recall that we haven't closed our garage door or haven't switched off the stove, and using our internet-enabled wireless mobile device we send a command to our Home Appliance Control System (HACS) to either close the garage door or switch the stove off. However, how can we be sure that the command was executed and that the desired situation, for example, the closed garage door or the switched-off stove, was reached? This paper proposes a technique for constructing reliable HACS's (or RHACS) using the concept of forward view and reverse view, where a view includes not only the physical path but also the control intelligence for that path. RHACS will not only help people remotely control devices at home but also increase confidence that their commands were effective with no unanticipated side-effects. A brief definition of reliability is the probability of good working of a system - however, our survey of the literature indicated that there is no consensus on this definition. Our analysis of a typical HACS indicated that its reliability depended on three major factors - reliability of software, reliability of hardware, and reliability of the network. As a case-study we considered a HACS configuration that included a washer, dryer, garage door opener, stove and a camera, and explored how the reliability of this system could be improved using the view-based approach. Concentrating on the network reliability aspect we explored three different techniques to improve the overall system reliability: standard protocol (X10) for the forward and reverse views, standard protocol (X10) for the forward view and the wired Ethernet for the reverse view, standard protocol (X10) for the forward view and the wireless Bluetooth for the reverse view. We used the NFR Framework to systematically analyze and evaluate reliability of HACS while at the same time accommodating the varying definitions of reliability, and we validated these evaluations using simulations. While further work needs to be done to determine the effectiveness of this approach to other reliability factors, we believe that this study demonstrates the practicality of the view-based approach to methodically analyze and construct reliable HACS with almost negligible overhead.","PeriodicalId":385396,"journal":{"name":"2006 IEEE Region 5 Conference","volume":"26 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":"132975100","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}

Biometric systems using a single biometric trait for authentication purposes have some limitations. In order to overcome this we are investigating multiple sensors that capture different biometric traits. Multimodal biometrics has the potential to overcome these limitations by improving system security levels and increasing the accuracy. This paper focuses on fingerprint verification as part of a fusion of biometric modalities such as voice and fingerprint. Fingerprint verification is one of the most reliable biometric techniques for personal identification. We determined that to merge the fingerprint system with voice verijication we need to develop our own algorithms for fingerprint verification. We describe the design and implementation of a fingerprint verification system that operates in two stages: minutia extraction and minutia matching. An improved version of the minutiae extraction algorithm was identified in literature and is implemented for extracting features from fingerprint images.","PeriodicalId":385396,"journal":{"name":"2006 IEEE Region 5 Conference","volume":"88 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":"123541194","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}

Combining wavelength and code multiplexing techniques generates an O3 circuit-switched network with a data capacity of up to 5.7 Tb/s on each point-to-point link in the network.

The method is based on the concept of non traditional, tensor and paired forms of representation of the 3-D image with respect to the 3-D discrete Fourier transform (DFT). Such representations use a minimal number of projections. The proposed algorithm is described in detail for an image (N × N × N), where N is a power of two. A multi-ring scanner that has contiguous rings of detectors stacked on top of each other is considered. The measurement data set containing specified projections of the 3-D image are generated according to the paired representation, and the proposed algorithm is tested on the data.

Many techniques have taken advantage of the received signal strength (RSS) measurement for location estimation in wireless sensor networks, since no special hardware implementation is required to measure RSS in almost all kinds of wireless systems. In this paper, two such techniques, MDS method and MLE that are recently proposed for collaborative location estimation, are studied in detail. From the theoretical formulation of the RSS-based location estimation problem, it is seen that MLE is more appropriate than MDS method. However, from simulation studies of both algorithms, which are iterative in nature, it is found that MLE is more sensitive to initial estimate than MDS method. Therefore, in this paper we propose to integrate these two techniques in series so that an estimate is first obtained using MDS method by taking advantage of its better convergence property, then MLE is employed to fine-tune the solution of MDS method to remove modeling errors that are inherent in MDS method. Through extensive simulations it is demonstrated that the new integrated method, named MDS-MLE, consistently outperforms both MDS method and MLE in various simulation scenarios. In this paper, we also address many important issues in collaborative localization, including effects of sensor node density, reference node density, and different deployment strategies of reference nodes.","PeriodicalId":385396,"journal":{"name":"2006 IEEE Region 5 Conference","volume":"8 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":"122176923","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}
