Introduzindo o ensino da astronomia através da astronomia observacional
(Universidade Federal de São CarlosUFSCarCâmpus SorocabaFísica - FL-So, 2020-12-18)
Heavenly bodies can be observed everywhere in the night sky. With the naked eye we can identify around 6000 stars spread across 88 constellations. Faced with this countless number of stars, astronomy offers us the opportunity ...
A Sea-Breeze Case Study in the La Plata River Region Using Local Observations, Satellite Images, and Model Simulations
(Springer, 2020-10)
Two well-developed sea-breeze cases in the La Plata River region, selected from a 5-month summer period, are studied using local observations, satellite images, and hydrostatic boundary-layer model simulations. Both the ...
Collaboration, information seeking and communication: an observational study of software developers' work practices
(Graz Univ Technolgoy, Inst Information Systems Computer Media-Iicm, 2011)
Different aspects defining the nature of software engineering work have been analyzed by empirical studies conducted in the last 30 years. However, in recent years, many changes have occurred in the context of software ...
Pedestrian crossing behavior, an observational study in the city of Ushuaia, Argentina
(Taylor & Francis, 2018-04)
Objectives: Pedestrian crashes are a critical problem in Latin American countries. However, little research has been published about pedestrians and even less about their behaviors in a naturalistic context. The objective ...
Learning Reward Machines: A Study in Partially Observable Reinforcement Learning
(2023)
Reinforcement Learning (RL) is a machine learning paradigm wherein an artificial agentinteracts with an environment with the purpose of learning behaviour that maximizesthe expected cumulative reward it receives from the ...
Evaluation of Three Methods to Estimate Density and Detectability From Roadside Point Counts
(Universidad Nacional, Costa Rica., 2011)
Roadside point counts are often used to estimate trends of bird populations. The use of aural
counts of birds without adjustment for detection probability, however, can lead to incorrect population trend
estimates. We ...
Should we worry about the observer effect? Evidence from Pelotas
(2016-04-12)
Most social sciences and medical studies assume that being observed does not affect subjects' behavior. However, interviews may cause changes in individuals' behavior or may inhibit changes which would occur if they were ...
Estudo de um sistema de controle sensorless para máquinas síncronas de ímãs permanentes internos
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2023-03-06)
This paper presents a study of state observers for the control of permanent magnet synchronous electric machines. In order to ensure the correct functioning of the machine, control techniques employed in PMSMs require ...
