There are many well-known face recognition technologies have been proposed such as the linear discriminant analysis (LDA), discrete cosine transform (DCT), principal component analysis (PCA), and local binary pattern (LBP). In this study, we implemented an LBP-based visitor access control system for the senior citizen. The embedded platform to install the LBP is Raspberry Pi. The OpenCV is adapted as the classifier and the USB camera is used as the input device for capturing the face images. The Eigenvectors of the images in the training set are compared with the input face image for identify a person. The experimental results show that the implemented system can achieve 90% face recognition rate. The implemented system is low-cost and suitable for developing the visitor access control system for the senior citizen.","PeriodicalId":148453,"journal":{"name":"2017 International Conference on Fuzzy Theory and Its Applications (iFUZZY)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125098005","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}

To achieve the desired performance during high-speed driving, both the kinematic and dynamic models of the vehicle are considered. Within the fuzzy-model-based framework, an approach to the fuzzy dynamic output feedback controller design is proposed. The desired yaw rate of the vehicle is regarded as the external disturbance of the vehicle lateral dynamics, which are norm-bounded uncertainties and can be approximated by the curvature of the reference path. By adopting the dynamic model in terms of error with respect to centerline of the reference road and Lyapunov stability theory, a sufficient condition to derive the fuzzy H∞ dynamic output feedback controller is developed. Moreover, to further improve the performance of the overall closed-loop system, the feedforward loop is introduced by estimating the desired steering angle under certain vehicle velocity. The effectiveness of the proposed approach is demonstrated by the co-simulation between Matlab/Simulink and Carsim.","PeriodicalId":148453,"journal":{"name":"2017 International Conference on Fuzzy Theory and Its Applications (iFUZZY)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128456519","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}

If an input heartbeat has a cross-correlation coefficient of less than 0.6 or a mean-square difference larger than 1.0 in comparison with the template, it is identified as abnormal. The study results show that if the normal template is not updated with the heart rate, normal heartbeats may be misjudged as abnormal when exercise changes the heart rate and heartbeat waveforms. The results also demonstrate that the proposed method can accurately identify abnormal heartbeats of ventricular fibrillation (VF) and ventricular tachycardia (VT) using ECG records 426 and 607 from the Malignant Ventricular Arrhythmia Database.","PeriodicalId":148453,"journal":{"name":"2017 International Conference on Fuzzy Theory and Its Applications (iFUZZY)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132493339","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}

By utilizing the parallel distributed compensation, the fuzzy polynomial controller is designed.

The rotary type of the inverted pendulum showed rather complicated to implement its control and maintain its stability than a linear one.

The paper thus proposed a policy by using combination of LQR and refined PID control to maintain the inverted balance of the pendulum.
