The proposed transformers are optimized for the implementation on flexible liquid crystal polymer (LCP) substrates. The signal trace and the adjacent ground planes in the conventional CPW structure are width-modulated along the propagation path of the electromagnetic wave while maintaining a constant ground-trace separation. Validation is carried out by designing and simulating several matching transformers at different frequency bands. Specifically, single-, multi-, and wideband transformers operating at 1 GH, 0.9, 3.6, 5.4 GHz, and 1–3 GHz, respectively, are designed. Full-wave simulation results verify the proposed design procedure.","PeriodicalId":238720,"journal":{"name":"2017 IEEE 30th Canadian Conference on Electrical and Computer Engineering (CCECE)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134110130","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 approach, the noisy speech signal is enhanced simultaneously in the spectral domain, using a minimum mean square error (MMSE) short time spectral amplitude estimator, and in the spectral modulation domain, using a MMSE spectral modulation magnitude estimator. The results of both estimators are then weighted and combined together, using a function based on the a posteriori SNR, to produce the desired enhanced signal. Comparative results using both the segmental SNR and PESQ objective measures are presented for both stationary and non-stationary noises. It is observed that the proposed approach suppresses more noise than the compared approaches, but at the usual compromise of introducing speech distortions.","PeriodicalId":238720,"journal":{"name":"2017 IEEE 30th Canadian Conference on Electrical and Computer Engineering (CCECE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133884196","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}

It identifies the user legitimacy accessing any service over the network. Authentication can usually be done by a simple single-factor authentication method such as a password. Unfortunately, it is inadequate to ensure security when accessing variant resources and services across the Internet. Therefore, for users to authenticate their identity, there is always a need to work on a different security method that could be used as an extra layer of security can be implemented. This paper presents a human dynamic-based user authentication, relying on the assumption that the actions and interactions of personal, interpersonal, and social factors of a user would be very hard to impersonate. Furthermore, the study includes experiments to help understand human dynamics in dealing with individuals, groups, and societies to be the essential aspects for the new generation user authentication.","PeriodicalId":238720,"journal":{"name":"2017 IEEE 30th Canadian Conference on Electrical and Computer Engineering (CCECE)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134615230","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}

It is also shown that the implemented ECG circuit can outperform the conventional right-leg driven systems when the signal paths are matched.

Principal Component Analysis (PCA) based K-means clustering have been successfully introduced and used in many clustering applications. However, PCA suffers from being relatively more sensitive to the noise due to having a linear transformation. On the other hand, Sparse Principal Component Analysis (SPCA) has a superior performance in relation to noise because of l1 and l2 norm additional terms which increase its robustness. As such, we propose SPCA based K-means clustering for defect segmentation. Principal Component Thermography (PCT) and Candid Covariance-Free Incremental Principal Component Thermography (CCIPCT) are also used as a pretreatment of data in order to reduce the number of components. Three types of specimens (CFRP, Plexiglass and Aluminum) have been used for comparative and quantitative benchmarking even in the case of adding Gaussian noise (0%– 35%). The results conclusively indicate the promising performance and confirmed the outlined properties.","PeriodicalId":238720,"journal":{"name":"2017 IEEE 30th Canadian Conference on Electrical and Computer Engineering (CCECE)","volume":"137 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133731233","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 proposed microgrid mainly consists of hybrid photovoltaic/wind sources, a synchronous generator, a battery storage and a load. The microgrid is able to provide a power factor correction close to unity in the grid-connected mode. Moreover, it can regulate the MG voltage and frequency through the contribution of the photovoltaic and wind sources in the islanding mode. An islanding detection method is used as a trigger for transition between grid-connected and islanding control modes. The effectiveness of the proposed model is investigated via MATLAB simulation. The simulation results highlight the capability of the proposed technique in controlling the voltage and frequency as well as in providing a power factor of unity (PF = 1) regardless the load change.","PeriodicalId":238720,"journal":{"name":"2017 IEEE 30th Canadian Conference on Electrical and Computer Engineering (CCECE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115705692","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 non-existence of the pure strategy Nash equilibrium was proven in closed-form when the defender/attacker have the incentive to defend/attack the frequency channel.
