ABSTRACT
The consumption of drinking water in the populations in the last 20 years has varied for different reasons, thus, it is necessary to determine its behavior for sustainable use of the resource. The objective of this work was to present the variation in drinking water consumption during the Sars-Cov-2 health emergency through dynamic modeling in the city of Macas in the Amazon region of Ecuador. The integrated moving average autoregressive model was used for the study (ARIMA), predicting the behavior of drinking water consumption for the year 2021 in the different neighborhoods of the city and relating this result with socioeconomic variables. The prediction for the year 2021 presented a decrease of 0.21% in the volume consumed compared to 2020, in April 2021 an increase of 85.21% was observed compared to the consumption of 2019, which can be attributed to the effects of the pandemic. The highest water consumption occurred in the cluster of neighborhoods with the highest population density, medium-high socioeconomic status, and high availability of basic services. The study aims to provide a valid alternative for decision-making in the framework of a health crisis, as well as possible conflicts in vulnerable areas in the face of the pandemic that affects the entire world. © 2021, Springer Nature Switzerland AG.
ABSTRACT
Software repositories contain information about source code, software development processes, and team interactions. We combine the provenance of development processes with code security analysis results to provide fast feedback on the software’s design and security issues. Results from queries of the provenance graph drives the security analysis, which are conducted on certain events—such as commits or pull requests by external contributors. We evaluate our method on Open Source projects that are developed under time pressure and use Germany’s COVID-19 contact tracing app ‘Corona-Warn-App’ as a case study. © 2021, Springer Nature Switzerland AG.
ABSTRACT
The emergency caused by COVID-19 exposed significant challenges for Higher Education Institutions. Beyond the connectivity defiance and the technological infrastructure required to give continuity to the learning processes, professors' digital skills development has been an essential part in addressing these challenges. This work shows how the use of a MOOC can help professors to migrate from the classroom environment to the virtual one. The paper explores the phases and methodologies implemented in the MOOC designing. Results revealed that 90% of the participants demonstrated superior skills in the management of tele-education tools, 70% of them were capable to scheduled assignments and 60% designed create online exams properly after the training. © 2020 IEEE.
ABSTRACT
Software repositories contain information about source code, software development processes, and team interactions. We combine provenance of the development process with code security analysis to automatically discover insights. This provides fast feedback on the software's design and security issues, which we evaluate on projects that are developed under time pressure, such as Germany's COVID-19 contact tracing app 'Corona-Warn-App'. © 2020 Owner/Author.
