Advancing EEG classification with transformer architecture: a case study on P300 potentials for assistive devices

Abstract: In this investigation, the Transformer architecture is applied to classify P300 event-related potentials in publicly available EEG data to augment assistive communication devices for individuals with impaired communication abilities. A detailed analysis comparing the Transformer model to established algorithms documented in the literature demonstrates its effectiveness in terms of Leia mais…

Evaluation method for hygrothermal performance of masonry rendering mortars: assessing moisture and mould growth risk under brazilian climate conditions

Abstarct: The presence of moisture in environments, when it exceeds certain limits and is associated with specific temperature ranges, can promote the growth of mould fungi inside buildings, compromising the health of occupants and leading to other harmful pathological manifestations affecting building performance. In this context, rendering mortars with paint Leia mais…

Propriedades e aspectos do concreto aparente do patrimônio da arquitetura moderna brasileira

Resumo: O objetivo do estudo é investigar propriedades e aspectos do concreto aparente das empenas do edifício Vilanova Artigas e correlacioná-los ao estado de conservação, visando oferecer subsídios para preservação. O edifício completou 50 anos em 2019 e foi submetido a reparos estruturais recentemente (2013-2015). Ensaios laboratoriais e observações “in Leia mais…

Using electrical resistivity tomography to understand the hydrogeological behavior of acid drainge percolation in a fractured aquifer at a uranium mining site

Abstract: Brazilian mining ventures aged 30 years or older were studied, revealing historical oversights in environmental planning that have caused substantial environmental liabilities during active mining and decommissioning. Electrical resistivity tomography surveys were conducted in a decommissioning uranium mine in southeast Brazil. The results provided valuable insights into local hydrogeological dynamics, Leia mais…

Chikungunya-driven gene expression linked to osteoclast survival and chronic artharalgia

Abstract: Chikungunya fever (CHIKF), caused by the Chikungunya virus (CHIKV), manifests as acute febrile illness often associated with polyarthritis and polyarthralgia. Although the acute symptoms resolve within two weeks, many patients experience prolonged joint pain and inflammation, resembling rheumatoid arthritis (RA). This study aimed to identify molecular markers related to Leia mais…

Chemical constituents of Coccoloba peltata Schott leaves and Their cytotoxic activities

Abstract: Chromatographic fractionation of CH2Cl2:MeOH (1:1) extract of Coccoloba peltata Schott cultivated in Egypt afforded four compounds, lupeol acetate (1), ent-13-epi-manoyl oxide (2), 5-methoxymethyl7,8-dimethyltocol (3), and α-tocopherol quinone (4). The planar structures of the isolated compounds were concluded based on HRESIMS and NMR spectroscopy. X-ray crystallography of 2 is reported Leia mais…

Thermochemical biomass conversion process in a small-scale fluidized bed reactor: fast pyrolysis of eucalyptus wood and gasification of sugarcane straw

Abstract: his paper presents the results of two process for thermochemical conversion of biomass, the fast pyrolysis of eucalyptus wood, and the gasification of sugarcane straw, both in a lab scale fluidized bed reactor. The bio-oil yield obtained from pyrolysis of eucalyptus wood was 64,4 wt%, water content of 31 Leia mais…

Sugarcene biorefinery: unlocking the potential of the pyrolytic process to convert waste biomasses into value-added products

Abstract: The sugarcane industry generates significant amounts of waste, such as bagasse (SCB) and sugarcane straw (SCS), which can be reused as raw materials to produce a wide range of renewable chemicals. This study, employing an approach that integrates kinetic studies and comprehensive product characterization, assessed the potential of pyrolysis Leia mais…

Estudos de ruptura de um talude em paleovale com solos coluvionar e residual pelo método simplificado de biship e retroanálise computacional da ruptura já existente

Resumo: Este artigo apresenta e discute os procedimentos técnicos adotados na elaboração de projeto para a estabilização de um maciço em corte, que já havia sofrido ruptura parcial, decorrente das condições geológico-geotécnicas locais e associada à precipitação ocorrida na época do colapso. Estudos efetuados indicaram que a solução de retaludamento Leia mais…
