Potencial uso de aguas grises en infraestrtura verde
La infraestructura verde, que incluye techos y muros verdes, requiere usualmente riego para su desarrollo y obtener los beneficios ecosistémicos. Sin embargo, gran parte de Chile sufre escasez hídrica la cual se incrementará con ekl cambio climático. Por lo tanto hay que buscar otras alterntaivas de riego más sustentables, tales como el uso de aguas grises. El objetivo del Ipre es identificar y evaluar alternativas para esta tecnología en Chile y el mundo, y realizar propuesta de implementación. Existirá la posibilidad de implementar un sistema en Laboratorio de Infreaestructura Vegetal de Edificios (LIVE) y su correspondiente monitoreo. Tiene un método de evaluación Nota 1-7, con 10 créditos y tiene 1/1 vacantes disponibles |

Multiresolution analysis and superresolution
Multiresolution analysis consists in constructing a filtration of L2 of closed subspaces Vj such that each one represents functions at a scale 2j. The ortogonal projection onto Vj represents the approximation at scale 2j whereas the difference between the projections onto Vj and Vj+1 represents the details at scale 2j. A typical signal distortion process consists in removing structure at small scales. This is modeled through convolutions and resampling. Is it possible to leverage multiresolution analysis to recover the missing details? In this case we do not want to solve the problem for any function, thus constraining the worst-case, but only for those that are of interest and have been distorted by the process under study. The goal of this iPre is to review the existing literature connecting multiresolution analysis with this problem, and to propose a mathematical model that would allow us to answer this question.

Study about the electrophysiological decoding of cognitive processes
This study will analyze the rhythmic activity of the electrophysiological signals produced by the brain, which is one of the most approachable manifestations of the brain activity underlying cognitive functions. One of the most important tasks in this approach is to select the relevant information and filter the environmental and internal noise. Therefore, an algorithm must be implemented that allows the raw data to be extracted and transformed into a signal that corresponds to the cognitive processes that are being evaluated. In this course, the student must implement algorithms for classification, decoding and description of the oscillatory activity of the EEG signal in humans, during the development of tasks that mainly assess memory and attention. For this we will use standard computational signal analysis tools.

Mathematical methods for the deconvolution problem
One of the main properties of an optical system is its resolution. This is defined as the minimum separation between two ideal point sources so that they can be distinguished from one another when observed through the system. In practice, the diffraction of light imposes a physical limit to the resolution of the system. For a linear system, this process is typically modeled by a convolution by the Point Spread Function (PSF). For this reason, a technique that improves the resolution of the system can be interpreted as a deconvolution method. The objective of this project is to study mathematical methods proposed in the literature in the past decade, which combine applied Fourier analysis, convex optimization, and probability, for which there exists conditions that ensure they solve the superresolution problem in a computationally efficient manner.

Seismic risk - Fragility curves for structural systems for coastal cities of the central zone of Chile
The objective of this research is to select the curves of fragility more appropriate to perform risk analysis earthquake-tsunami in the central zone of Chile. To achieve this goal we propose three main activities: (i) comprehensive review of the state of the art curves of fragility for types of structural scenarios and seismic chileans; (ii) evaluate scenarios of seismic risk in the commune of San Antonio and to compare the results obtained by using different curves of fragility; (iii) selection of the curves more appropriate for the chilean case. The student will be part of a research team of the Research Center for Integrated Risk Management of Disasters (CIGIDEN). This research team focuses on the development and update of the computing platform Disaster Research Workflow (DRW).
