Digital twin environment for Forestry 4.0 application using a CAN Bus architecture
Spencer, Geoffrey; Dionísio, Rogério Pais; Neto, Luis; Torres, Pedro; Gonçalves, GilThis paper presents a digital twin demonstrator of a forest harvesters and wood processing machines. The demonstrator is a cyber-physical system that allow the emulation and identification of faults that may occur during regular machine operations. The proposed solution includes a CAN Bus communication between several electronic controller units connected to sensors and actuators.
Citrus aphids in Algarve Region (Portugal): Species, hosts, and biological control
Paiva, Paulo Eduardo Branco; Neto, Luis; Marques, Natália; Duarte, Beatriz; Duarte, AmilcarAphids affect citrus by causing leaf deformations and reducing fruit production. Additionally, aphids are a great concern due to their ability to transmit Citrus tristeza virus (CTV), the cause of tristeza, one of the main citrus diseases. In the last four years, citrus orchards in the south of Portugal (Algarve region) were sampled for aphid species identification and counting. Aphis spiraecola was the most ab...
Immersive Virtual Reality Training Platforms Powered by Digital Twin Technologi...
Machado, Rui; Rodrigues, Ricardo; Neto, Luis; Barbosa, Luís Filipe; Melo, MiguelThe high costs associated with implementing and maintaining a training program based on immersive Virtual Reality (VR) technologies are a barrier to its adoption and widespread. This paper presents an Immersive VR training platform that intends to overcome such barriers. The Immersive VR platform was developed based on a real-usage case study conducted with an industry adopter. The case scenario focuses on trai...
Water vapor pressure deficit in Portugal and implications for the development o...
Paiva, Paulo Eduardo Branco; Cota, Tânia; Neto, Luis; Soares, Celestino; Tomás, José Carlos; Duarte, AmilcarAfrican citrus psyllid (Trioza erytreae (Del Guercio)) is a vector insect of the bacterium Candidatus Liberibacter africanus, the putative causal agent of Huanglongbing, the most devastating citrus disease in the world. The insect was found on the island of Madeira in 1994 and in mainland Portugal in 2015. Present in the north and center of the country, it is a threat to Algarve, the main citrus-producing regio...
Cyber-physical production systems supported by intelligent devices (smartboxes)...
Torres, Pedro; Dionísio, Rogério; Malhão, Sérgio; Neto, Luis; Ferreira, Ricardo; Gouveia, Helena; Castro, Helderndustry 4.0 paradigm is a reality in the digitization of industrial processes and physical assets, as well as their integration into digital ecosystems with several suppliers of the value chain. In particular, Industry 4.0 is the technological evolution of embedded systems applied to Cyber-Physical Systems (CPSs). With this, a shift from the current paradigm of centralization to a more decentralized production,...
Áreas de gestão fitossanitária para Ceratitis capitata e Trioza erytreae: nova ...
Paiva, Paulo; Neto, Luis; Duarte, AmilcarO controlo de pragas em áreas de gestão fitossanitária - AGF - (area wide pest management) é uma extensão da proteção integrada aplicada a uma praga alvo numa dada área geográfica, geralmente envolvendo várias explorações agrícolas e áreas vizinhas com plantas hospedeiras ou de refúgio do organismo alvo. Estas áreas incluem, para além das explorações comerciais, culturas abandonadas, hospedeiros alternativos e ...
Report of in vitro antileishmanial properties of Iberian macroalgae
Bruno De Sousa, Carolina; Lago, Joao Henrique G.; Macridachis, Jorge; Oliveira, Marta; Fonseca Brito, Luis; Vizetto-Duarte, Catarina; Florindo, ClaudiaHere is reported the anti Leishmania infantum activity of 48 hexane, CH2Cl2 and MeOH extracts from 16 macroalgae collected on the Iberian Coast. Seven hexane and CH2Cl2 Cystoseira baccata, Cystoseira barbata, Cystoseira tamariscifolia, Cystoseira usneoides, Dictyota spiralis and Plocamium cartilagineum extracts were active towards promastigotes (IC50 29.8-101.8 mu g/mL) inducing strong morphological alterations...

Pereira, Luísa Dias; Neto, Luis; Bernardo, Hermano; Silva, Manuel Carlos Gameiro daThis work is part of a wider research project called Energy Efficient Schools (Escolas Energeticamente Eficientes, 3Es), granted by Teixeira Duarte in the framework of the Portuguese Program of R&D Projects associated with Large Public Tenders. The authors are thankful to Parque Escolar E.P.E. for the provision of the database on the Portuguese secondary schools. The presented work is framed under the Energy fo...
Reproductive efficiency of entomopathogenic nematodes as scavengers. Are they a...
Blanco-Pérez, Rubén; Bueno-Pallero, Francisco Ángel; Neto, Luis; Campos-Herrera, RaquelEntomopathogenic nematodes (EPNs) and their bacterial partners are well-studied insect pathogens, and their persistence in soils is one of the key parameters for successful use as biological control agents in agroecosystems. Free-living bacteriophagous nematodes (FLBNs) in the genus Oscheius, often found in soils, can interfere in EPN reproduction when exposed to live insect larvae. Both groups of nematodes can...
No induction of antimicrobial resistance in Staphylococcus aureus and Listeria ...
Apolonio, Joana; Faleiro, Maria L.; Miguel, Maria Graca; Neto, LuisThe aim of this study was to evaluate the adaptation response of Staphylococcus aureus, methicillin-resistant S.aureus (MRSA), and Listeria monocytogenes to the essential oil (EO), eugenol, and citral. The minimum inhibitory concentration of eugenol and citral was determined by agar dilution and microdilution. Adaptation to eugenol and citral was done by sequential exposure of the pathogens to increasing concen...
