The wide implementation of DAB converters in electrical applications such as power generation, power distribution and energy management shows the great potential in electrical energy conversion. The DAB converter topology consists in the interface of two single-phase power converter bridges through a high frequency transformer, which allows DAB converter to reach different power rates. DAB converters have several advantages respect to conventional electromechanical transformers, such as: electrical energy efficiency, low size and weight. This paper proposes a Sliding Mode Controller (SMC) with integral linear quadratic surface to regulate power distribution by changing the phase shift between the primary and secondary commutations of the semiconductors in each bridge. In order to test the SMC performance on robustness, load variation and reference tracking tests are applied. The SMC operation is evaluated through the criterion of the Integral of the Absolute value of the Error (IAE) and conclusions are developed from analysis of results.","PeriodicalId":334574,"journal":{"name":"2018 IEEE Third Ecuador Technical Chapters Meeting (ETCM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130230141","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}

Said mechanism is built via Google Brain’s TensorFlow (as regards facial identity recognition) and Google Cloud Platform’s Cloud Vision API (as regards facial gesture recognition); and it is integrated into the ongoing development of an intelligent built-environment framework, viz., Design-to-Robotic-Production & -Operation (D2RP&O), conceived at Delft University of Technology (TUD). The present work builds on the inherited technological ecosystem and technical functionality of the Design-to-Robotic-Operation (D2RO) component of said framework; and its implementation is validated via two scenarios (physical and computational). In the first scenario—and building on an inherited adaptive mechanism—if building-skin components perceive a rise in interior temperature levels, natural ventilation is promoted by increasing degrees of aperture. This measure is presently confirmed or negated by a corresponding facial expression on the part of the user in response to said reaction, which serves as an intuitive override / feedback mechanism to the intelligent building-skin mechanism’s decision-making process. In the second scenario—and building on another inherited mechanism—if an accidental fall is detected and the user remains consciously or unconsciously collapsed, a series of automated emergency notifications (e.g., SMS, email, etc.) are sent to family and/or care-takers by particular mechanisms in the intelligent built-environment. The precision of this measure and its execution are presently confirmed by (a) identity detection of the victim, and (b) recognition of a reflexive facial gesture of pain and/or displeasure. The work presented in this paper promotes a considered relationship between the architecture of the built-environment and the Information and Communication Technologies (ICTs) embedded and/or deployed.","PeriodicalId":334574,"journal":{"name":"2018 IEEE Third Ecuador Technical Chapters Meeting (ETCM)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125190930","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}

Therapeutic procedures include the utilization of orthoses or insoles that are placed inside the footwear. Design of personalized insoles is a process that includes several stages. An important stage is the acquisition and analysis of footprint images. Their segmentation enables quantification of the footprint shape by estimating several indices that allow classification and diagnosis of foot morphology abnormalities. A segmentation method for footprint images using Level-Set algorithms is reported. Two area based Level-Set segmentation algorithms were applied. The first is the Chan-Vese algorithm using a global minimizer. The second is the Lankton algorithm that implements the Chan-Vese energy function using a localized minimizer and the Sparse Field Method for reducing the computational cost. Algorithms tested are accurate for segmenting the footprint images, providing an average Dice coefficient higher than 0.93. The Lankton algorithm is robust with respect to spatial variation in intensities within the footprint shape. It is also fast as the average time for segmenting one image is only 6.4 seconds.","PeriodicalId":334574,"journal":{"name":"2018 IEEE Third Ecuador Technical Chapters Meeting (ETCM)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125259505","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}

Currently, there is no support system for the patient to remotely perform the exercises for recovery. The application aims to reduce recovery costs as well as to provide access to health at a low cost. Therefore, it is important to have a web system accessible to all users. To achieve this parameter, and to determine if it provides information accessible to all, regardless of the physical capabilities of the users, the accessibility guidelines were applied in accordance with the Web Content Accessibility Guide (WCAG) 2.0 and Website Accessibility Evaluation Methodology 1.0. This study presents an evaluation of the website’s accessibility using automatic tools and an analysis to improve the accessibility of the platform providing elderly patients with an accessible and inclusive website. The preliminary results of our research show that the telerehabilitation platform requires improvements to comply with certain levels of web accessibility.","PeriodicalId":334574,"journal":{"name":"2018 IEEE Third Ecuador Technical Chapters Meeting (ETCM)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130578753","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}
