An open channel flow, or also called micro-canal is used to study river floods, scour around coast structures and bridge piers scour. The need for multiple measurement water speed points, in such a way that specific sections of the micro-canal could be controlled, motivated this research. However, the acquisition of high-end speed sensors involves high economic costs being difficult to implement. As a solution, we designed and implemented a micro-velocimeter (MSV) whose operation principle is based on the operation of a small D.C. motor in generator mode. The D.C. generator shaft is turned by a small propeller, which rotates according to the water speed inside the micro-canal. The prototype was designed using AUTOCAD software, simulated by SolidWorks software and built by 3D printing. For the implementation, the MSV was calibrated using an available Acoustic-Doppler Velocimeter (ADV). The MSV is a good alternative for realizing multi-point measurements along of a micro-canal or with a matrix arranged in a specific section or both, in a simple and economical form.","PeriodicalId":223855,"journal":{"name":"2019 IEEE CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON)","volume":"56 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120839368","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}

Specifically, we exploit the theory behind M-Estimators to incorporate robustness into the sparse coding stage of K-SVD, and hence, decrease the estimation bias that might be introduced when outliers are present. Five different M-Estimators are introduced alongside their optimal hyperparameters in order to avoid parameter tuning by the user. In this way, the proposed framework has the same number of free parameters as K-SVD with the added feature of robustness and improved performance in non–Gaussian environments. We thoroughly demonstrate the superiority of the proposed algorithms via recovery of generating dictionaries for synthetic data and image denoising under two types of non–homogenous noise—salt and pepper noise, and impulsive noise.","PeriodicalId":223855,"journal":{"name":"2019 IEEE CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128541939","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}

This is the reason why the present research will be focused on the measure of this index, using both qualitative and quantitative variables to estimate the grade of development of the countries in South America for the year of 2016, considering the variables of impact in this part of the region. The entropy weight method, on the basis of Shannon’s entropy theory, was applied in order to produce a ranking which shows the social development level in the countries analyzed. To calculate the weight of the criteria, the entropy-weight method was employed, and then the countries surveyed were categorized by the outcomes of a weighted sum. Additionally, in this work an informative map of social development in the aforementioned countries is presented, which varies on a colored scale with the ranking data. The results of this study may help governments in making the best decision regarding the social development of their countries.","PeriodicalId":223855,"journal":{"name":"2019 IEEE CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128694391","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}
