This is because the stability may be destroyed when the denominator-coefficients of a variable-recursive-filter are changed on-line. Once such an instability occurs, all the filtering operations become meaningless. To solve the instability problem, this paper proposes a novel parameter-transformation method for transforming the original denominator-coefficients of a variable-recursive-filter into a set of new parameters, which can take arbitrary values while theoretically guaranteeing the stability of the designed variable-recursive-filter. After transforming the original denominator-coefficients into a set of new parameters, we also present a two-stage scheme for designing a variable-recursive-filter whose stability is always guaranteed. An example is given for demonstrating the theoretical stability-guarantee and the high-accuracy design.","PeriodicalId":292057,"journal":{"name":"TENCON 2014 - 2014 IEEE Region 10 Conference","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130686132","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}

PVC can occur in healthy people, but for those with frequent occurrence of PVCs, this can often be linked to pathological disorders of the heart. PVC detection allows the physician to diagnose heart disease accurately and also helps cardiac patients to be monitored effectively. This paper presents a novel algorithm for real-time PVC detection from ECG Lead II. Our methodology has low complexity in order to be applied to embedded devices. The developed algorithm is based on cardiac electrophysiology by considering 4 characteristics of ECG abnormalities, i.e. shorter RR-interval, wider QRS complex, changing of the QRS complex pattern and changing of the ST-level. The main parameters used in the algorithm are optimized to provide maximum performance of PVC detection. We tested the algorithm on 26 ECG records of MIT-BIH Arrhythmia Database. The performance of the proposed method has 97.75% of sensitivity and 98.80% of specificity. Furthermore, we also tested the algorithm on 16 selected records from Long-Term ST Database, with the results of 99.47% sensitivity and 99.24% specificity. The test results indicate that the algorithm presented in this work has high efficiency and high precision, which can be used to detect PVC for embedded devices in real-time.","PeriodicalId":292057,"journal":{"name":"TENCON 2014 - 2014 IEEE Region 10 Conference","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130749722","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 investigation, one signal conditioning was used for all electrodes hence hardware construction is simplified and power consumption is relatively low. In order to achieve that, switch configuration which could form analog multiplexer with small resistance and capacitance is required. Each electrode needs 4 analog switches, so that for 32 electrodes 128 analog switches are needed. The electrode is selectable according to desired function as excitation or detection.

If the voluntary blinks can be detected automatically, a decision can be made whether to use the eye blink as application input. If the entire eye blink process is captured, the wave pattern of an eye blink can be generated. We have developed a new method for measuring the wave pattern of an eye blink. Based on these wave patterns, feature parameters for eye blink type classification can be estimated. To develop an eye blink input interface suitable for practical use, the interface system utilizes a standard video camera, such as an NTSC-based model. Specifically, this system requires feature parameters that can be estimated by a standard video camera. In addition, if other application programs are executed while the eye-blink detection program is in use, the video capture sampling rate is decreased. In this paper, we present the feature parameters of voluntary and involuntary eye blinks, and discuss the changes that occur when the sampling rate is decreased.","PeriodicalId":292057,"journal":{"name":"TENCON 2014 - 2014 IEEE Region 10 Conference","volume":"53 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134603645","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 design of ground grid is discussed pertinent to its maximum touch and step voltage produced for a given GPR. The parameters are analyzed to ensure that they conform to the IEEE 80-2000. It is found that, for a given GPR, the maximum touch and step voltages of the rectangle grid, regardless its compression ratio, are lower than the square's. This means rectangle grid is safer than square one. The shape of ground grid is therefore one of the crucial factors in grid design, especially when grids are placed close together unconnected. This is the case when a new substation is constructing near one which is still energized. When there is a GPR, the touch voltage will be made worse by the two unconnected grids, and thus harm and damage personnel and sensitive equipment.","PeriodicalId":292057,"journal":{"name":"TENCON 2014 - 2014 IEEE Region 10 Conference","volume":"37 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124137224","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}

Devices are getting connected in the network plane for streamlined interoperability and to provide compound collaborative services; and although the expanded address space are proving handy they comes with added network management complexity. DHCPv6 assigns address to connected devices in ascending numerical order by default, while EUI-64 build address from MAC address value; hence in common skirmishes only the a least significant population of addresses are assigned depending on institution type. The abundant availability of unoccupied address motivates a new addressing scheme that dynamically assign address built as human perceptible information specific to corresponding node using combination of hex value prior to allocation. Device information are vastly available courtesy of many device identification methods such as NetBIOS and address book lookup, however there lacks a ubiquitous standard to properly define a device profile and their inherent attributes. A unified service discovery and aggregation are devised to collect device information, filter and dominate a tag that best represent the corresponding device, such as device type, device role or owner name. Embedding device information directly into IPv6 address are made possible with the large address space support. This gives rise to a perceptible and more management friendly addresses notation, in addition to being immune to record poisoning in resolving information directly from IP address, a privileges previously not afforded by conventional implementation.","PeriodicalId":292057,"journal":{"name":"TENCON 2014 - 2014 IEEE Region 10 Conference","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124306074","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}
