Resumo: O advento dos métodos de programação denominados "no code" e "low code" veio permitir que profissionais não informáticos pudessem se aventurar positivamente na criação de aplicações digitais relacionadas com a sua área de trabalho ou estudo, necessitando de conhecer um reduzido conjunto de aspetos técnicos das ferramentas utilizadas, algumas delas apresentadas aqui.2022-10-01T00:00:00ZLow Complexity Millimeter Wave Point-to-point Communication: Interference Assessment of BPSK vs QPSK DecompositionBorges, DavidViegas, PedroMontezuma, PauloDinis, RuiSilva, Mário Marques dahttp://hdl.handle.net/11144/54742022-06-21T09:16:57Z2019-06-19T00:00:00ZTítulo: Low Complexity Millimeter Wave Point-to-point Communication: Interference Assessment of BPSK vs QPSK Decomposition

Resumo: Power amplification and spectral e±ciencies could be optimized with transmitter
structures employing several branches, each one associated to a signal component of the symbol to
be transmitted, with an ampli¯er directly connected to an antenna or an antenna array. Under
these conditions the signal components transmitted by the several branches are associated to
di®erent beams to increase the separation among data streams from di®erent users. However,
even in these conditions interference among users can occur due to superposition of radiation
beams carrying signal components from di®erent users. Since the physical security level assured
by these structures is not negatively a®ected, it is crucial the assessment of interference e®ects
in such systems. Under certain limits in misalignments, simulation results show that beam
interference has low impact on system performance.2019-06-19T00:00:00ZRendezvous Algorithm for Disconnected TopologiesSilvestre, Danielhttp://hdl.handle.net/11144/46682021-02-26T16:52:15Z2020-09-01T00:00:00ZTítulo: Rendezvous Algorithm for Disconnected Topologies

Resumo: Multi-Agent Systems (MAS) - a network composed of mobile agents with the objective of converging to a single location.
No centralized infrastructure - implies the need for a decentralized algorithm to compute the actuation.
Applicable to exploration missions - a group of robots with the target of sensing as much ground as possible.
Typical solutions use consensus algorithms [1] [2], can cope with asymmetric wireless links.
Consensus algorithms can be made to work with noisy measurements [3].2020-09-01T00:00:00ZDecentralized Control using Flocking RulesRibeiro, R.Silvestre, D.Silvestre, C.http://hdl.handle.net/11144/46672021-02-26T16:22:08Z2020-07-01T00:00:00ZTítulo: Decentralized Control using Flocking Rules
