Title Algorithm for Processing Mammography: Detection of Microcalcifications Type
Year 2018 Publication Ieee Latin America Transactions Abbreviated Journal IEEE Latin Am. Trans.
Volume 16 Issue 9 Pages 2460-2466
Keywords Breast cancer; Image processing; Microcalcifications; X-ray image
Abstract A new algorithm based in Creme Filter, is proposed for breast cancer detection. The images obtained show micro calcifications with better contrast, allowing a better prognosis. The algorithm has only one parameter free, that permitting to observe texture when parameter is changed.

Title Inline Force Sensor Development for Electrical Motors for Mining Operations in Chile: A New Inspection Protocol Type
Year 2018 Publication Ieee Latin America Transactions Abbreviated Journal IEEE Latin Am. Trans.
Volume 16 Issue 1 Pages 66-74
Keywords electrical motor sensor; SAG grinding drill motor; inspection protocol
Abstract Electric motors are among the most widely used electro-mechanical systems in the mining industry in Chile. As they are physically present in virtually all phases of the production process, they must be regularly inspected. In order to maintain a maximum level of operability and to avoid the occurrence of catastrophic failures and unscheduled stoppages, regular, planned reviews to measure the internal parameters of their components are performed manually. This part of the process presents serious shortcomings, such as significant inspection times, information input errors and, in some cases, measurement errors resulting from the technical difficulty of physically taking the measurement. This research presents the design, development and evaluation of a new sensor to support the inspection of brush-holder spring tensions as well as the integration of a digital gauge to control other critical dimensions of the brush-holder mounting. Its purpose is to provide the mining industry with a new system and a fully automated inspection protocol to ease maintenance and control tasks, particularly focusing on reducing inspection times. These products are expected to increase the equipment operating life, as well as delivering a maintenance report of the motor's key parameters which directly benefits the Key Performance Indicators (KPI) of mining management

Title A Joint RSA Algorithm for Dynamic Flexible Optical Networking Type
Year 2015 Publication Ieee Latin America Transactions Abbreviated Journal IEEE Latin Am. Trans.
Volume 13 Issue 11 Pages 3531-3537
Keywords Dynamic optical networks; flexible grid; Routing and Spectrum Allocation
Abstract We propose a novel algorithm to solve the Routing and Spectrum Allocation (RSA) problem in dynamic flexible grid optical networks. Unlike most previous proposals, the algorithm solves the R and SA problems jointly by exhaustively searching the solution space and taking the network state into account. As a result, the shortest possible path with enough spectrum availability is allocated to establish the connections. Simulation results show that, in terms of blocking ratio, our proposal significantly outperforms previously proposed algorithms. In some cases, the performance is better by more than one order of magnitude.
