Studying the rotational dynamics of a meter stick using the Arduino board and 3...
Oliveira, Vitor; Brazil, Gustavo; Rodrigues, Paulo; Almeida, PedroPublisher Copyright: © 2024 The Author(s). Published by IOP Publishing Ltd.; We present a low-cost experimental apparatus designed for studying the rotational dynamics of a meter stick. This apparatus uses everyday laboratory supplies, 3D printed parts, and an Arduino board for data acquisition. It consists of a common bearing fixed to a vertical axle, connected to the meter stick through a 3D printed spindle a...

Projecto X
Graça, Jorge; Rodrigues, Helena; Rodrigues, PauloUIDB/00693/2020 UIDP/00693/2020; This article analyses and reflects upon a community music project that occurred in 2016 in Portugal. It involved a community of people with disabilities and a group of artists from different fields. The project’s promotors aimed to create a space in which differences were abated, social well-being was nourished and individual desires were fostered. This article endeavours to und...
Structural changes in the duration of bull markets and business cycle dynamics
Cruz, João; Nicolau, João; Rodrigues, PauloThis paper tests for structural changes in the duration of bull regimes in 18 developed and emerging economies’ adjusted market capitalization stock indexes, by using the novel approach of Nicolau (Econ Lett 146:64–67, 2016) as well as two additional new procedures introduced here; and investigates whether the structural changes detected in the bull markets’ duration are connected to the business cycle. We conc...
A re-examination of inflation persistence dynamics in OECD countries
Zsurkis, Gabriel; Nicolau, João; Rodrigues, PauloThis paper introduces a simple and easy to implement procedure to test for changes in persistence. The time-varying parameter that characterizes persistence changes under the alternative hypothesis is approximated by a parsimonious cosine function. The new test is the minimum of a t-statistic computed from a test regression that considers a set of reasonable values for a frequency term that is used to evaluate ...
Sediment Sampling in Estuarine Mudflats with an Aerial-Ground Robotic Team
Deusdado, Pedro; Guedes, Magno; Silva, André; Marques, Francisco; Pinto, Eduardo; Rodrigues, Paulo; Lourenço, André; Mendonça, Ricardo; Santana, PedroThis work was co-funded by the ROBOSAMPLERproject (LISBOA-01-0202-FEDER-024961). We would like to thank the anonymous reviewers for their valuable comments and suggestions.; This paper presents a robotic team suited for bottom sediment sampling and retrieval in mudflats, targeting environmental monitoring tasks. The robotic team encompasses a four-wheel-steering ground vehicle, equipped with a drilling tool des...
