A practical methodology of design of off-line reservoirs for reducing maximum water levels in urban channels
(2020-08-06)
Flooding can often occur in many places due to the increasing trend of rainfall events (climate change), the urbanization process of a catchment area, or by an undersized urban channel. Reservoirs are used for limiting ...
A Generic Materials and Operations Planning Approach for Inventory Turnover Optimization in the Chemical Industry
(2020-05-22)
Chemical industries usually involve continuous and large-scale production processes that require demanding inventory control systems. This paper aims to show the results of the implementation of a mixed-integer programming ...
A predictive model for the missing people problem
(2021-03-01)
The disappearance of people is a multidimensional phenomenon, in which several aspects must be considered. It affects people’s security perception and consumes police resources in its treatment. Therefore, does exists an ...
A machine learning model for emotion recognition from physiological signals
(Elsevier Ltd, 2020)
Emotions are affective states related to physiological responses. This study proposes a model for recognition of three emotions: amusement, sadness, and neutral from physiological signals with the purpose of developing a ...
