- The purpose of this study is to analyze the use of Simulation-Based Multi-Objective Optimization (SMO) for Reconfigurable Manufacturing System Configuration Analysis (RMS-CA). In doing so, this study addresses the need for efficiently performing RMS-CA with respect to the limited time for decision-making in the industry, and investigates one of the salient problems of RMS-CA: determining the minimum number of machines necessary to satisfy the demand. The study adopts an NSGA II optimization algorithm and presents two contributions to existing literature. Firstly, the study proposes a series of steps for the use of SMO for RMS-CA and shows how to simultaneously maximize production throughput, minimize lead time, and buffer size. Secondly, the study presents a qualitative comparison with the prior work in RMS-CA and the proposed use of SMO; it discusses the advantages and challenges of using SMO and provides critical insight for production engineers and managers responsible for production system configuration.

Fostering HCI Research in, by, and for Latin America
- 2020

In: Extended Abstracts of the 2020 CHI Conference on Human Factors in Computing Systems, CHI 2020. - New York, NY, USA : Association for Computing Machinery (ACM).

Conference paper (peer-reviewed)abstract
- Over the last 20 years, the Latin American Human-Computer Interaction (HCI) community has been working to shed light on how the diverse populations in the region are adopting, using, and making sense of computational technologies. Latin America's tense socio-political context, plurality of languages, collectivist culture, and historical relationship with the Global North make it a unique and rich space for HCI research. Considering the growing number of studies about Latin American communities and the emergent efforts to contribute to the HCI literature, we propose to host a SIG meeting at the 2020 ACM CHI conference. Our goal is to consolidate these efforts to better promote HCI research in, by, and for Latin America, by (1) bringing together researchers, practitioners, and students who are interested in engaging with Latin America through their research and practice, (2) envisioning a shared research agenda, and (3) identifying strategies for making its contributions more visible and impactful in the international community.

precisionFDA Truth Challenge V2: Calling variants from short- and long-reads in difficult-to-map regions
- 2020
-
Other publication (other academic/artistic)abstract
- The precisionFDA Truth Challenge V2 aimed to assess the state-of-the-art of variant calling in difficult-to-map regions and the Major Histocompatibility Complex (MHC). Starting with FASTQ files, 20 challenge participants applied their variant calling pipelines and submitted 64 variant callsets for one or more sequencing technologies (~35X Illumina, ~35X PacBio HiFi, and ~50X Oxford Nanopore Technologies). Submissions were evaluated following best practices for benchmarking small variants with the new GIAB benchmark sets and genome stratifications. Challenge submissions included a number of innovative methods for all three technologies, with graph-based and machine-learning methods scoring best for short-read and long-read datasets, respectively. New methods out-performed the 2016 Truth Challenge winners, and new machine-learning approaches combining multiple sequencing technologies performed particularly well. Recent developments in sequencing and variant calling have enabled benchmarking variants in challenging genomic regions, paving the way for the identification of previously unknown clinically relevant variants.
