“…In recent years, aeronautical accidents have occurred frequently, with consequences such as forced landings, minor damage, crashes of the aircraft, and passenger casualties [ 1 ], showing the great importance of aircraft safety to human life. Among these accidents, aeroengine wear failure is a significant cause [ 2 , 3 ].…”

Lubricating oil monitoring technology is a commonly used method in aeroengine condition monitoring, which includes particle counting technology, as well as spectral and ferrography technology in offline monitoring. However, these technologies only analyze the characteristics of wear particles and rely on physical and chemical analysis techniques to monitor the oil quality. In order to further advance offline monitoring technology, this paper explores the potential role of differences in wear particle kinematic characteristics in recognizing changes in wear particle diameter and oil viscosity. Firstly, a kinematic force analysis of the wear particles in the microfluid was carried out. Accordingly, a microfluidic channel conducive to observing the movement characteristics of particles was designed. Then, the wear particle kinematic analysis system (WKAS) was designed and fabricated. Secondly, a real-time tracking velocity measurement algorithm was developed by using the Gaussian mixture model (GMM) and the blob-tracking algorithm. Lastly, the WKAS was applied to a pin–disc tester, and the experimental results show that there is a corresponding relationship between the velocity of the particles and their diameter and the oil viscosity. Therefore, WKAS provides a new research idea for intelligent aeroengine lubricating oil monitoring technology. Future work is needed to establish a quantitative relationship between wear particle velocity and particle diameter, density, and oil viscosity.

“…O Modelo de Aceitação de Tecnologia (Technology Acceptance Model -TAM) vem sendo utilizado para a compreensão dos comportamentos relacionados à aceitação e ao uso da tecnologia computacional e de sistemas de informação (Maria, Frogeri, Piurcosky, & Prado, 2021). Davis (1989) propôs um modelo teórico de aceitação de tecnologia sob os pilares da utilidade percebida e facilidade de uso como pré-requisitos para o comportamento do indivíduo em aceitar ou não uma tecnologia.…”

Concebido originalmente para avaliar o uso profissional de um processador de texto, o TAM, após a inclusão de variáveis externas (Davis, Bagozzi, & Warshaw, 1989), foi adaptado para avaliar a intenção e o uso de diversas tecnologias (Maria et al, 2021).

To analyze the perception of students and teachers from federal and private HEIs regarding the usefulness and ease of use of the main Information System used by them in remote teaching/learning during the COVID-19 pandemic. A classic model from the field of technology acceptance (TAM) is adopted as a theoretical basis to observe a phenomenon that is recent and still under construction in its body of scientific knowledge. Study's results contribute to new variables associated with the phenomenon. Methodologically, the study contributed by analytical construction. To achieve the study's objective, a quantitative approach, hypothetical-deductive logic, and interpretivist epistemology were adopted. A total of 806 valid responses were collected. The data were analyzed using descriptive statistical techniques, clustering, correlation, analysis of variance, and regression. We observe that the attitude toward IS use adopted by HEIs during the pandemic by COVID-19 are influenced by Perceived Usefulness and Perceived Ease of Use, but differently for students and faculty. The study advances the technology acceptance literature by addressing a current issue that is aligned with the main challenges facing Brazilian Higher Education Institutions during the COVID-19 pandemic. In the management field, the results of the study suggest practices that can facilitate the use of information systems in the transition from face-to-face teaching to the remote modality.

“…O TAM 1 foi adaptado para avaliar a adoção de sistemas de informação com a incorporação de variáveis externas como características do sistema, envolvimento do usuário no desenvolvimento do sistema e natureza do processo de implantação (Davis & Venkatesh, 1996). O TAM 2 seguiu o mesmo objetivo do TAM 1 no sentido de adicionar variáveis que poderiam explicar melhor a adoção de sistemas de informação (Maria, Frogeri, Piurcosky, & Prado, 2021). Foram adicionadas variáveis que precederam o construto Utilidade Percebida (UP) como relevância do trabalho, qualidade de saída, demonstrabilidade de resultados e voluntariedade foram adicionadas ao modelo (Venkatesh & Davis, 2000).…”

O modelo UTAUT (Unified Theory of Acceptance and Use of Technology -Teoria Unificada da Aceitação e uso de Tecnologia) foi desenvolvido com o objetivo de unificar as propostas anteriores de modelos de aceitação de tecnologia que foram desenvolvidas (TAM, TAM 1 e TAM 2) (Maria et al, 2021). Adicionou-se ao UTAUT os construtos expectativa de desempenho, expectativa de esforço, influência social e condições facilitadoras (Venkatesh, Morris, Davis, & Davis, 2003).…”

The purpose of this Systematic Literature Review (SLR) is to provide an overview of the current state of research efforts on the application of TAM in the field of learning and teaching during pandemic COVID-19 and to identify gaps that can be explored in future studies. Our study presents an approach to a current theme, relevant to a literature still under construction and to society, especially to Institutions of Higher Education. Furthermore, the methodological approach adopted allowed us to identify the existing body of knowledge and opportunities for new research. Through the SLR a total of 113 studies were identified and analyzed with bibliometric techniques and lexical analysis. The results of the SLR were complemented by an online survey applied in two Higher Education Institutions. A total of 819 responses were collected and analyzed using descriptive statistics. We observed a growing scientific production Asian continent researchers and few publications from female researchers. Quantitative approaches performed by means of structural-equation-modeling made up a large part of the studies We did not identify univocally qualitative studies We did not observe studies focusing on the Google-Classroom or SIGAA IS. We believe that the study presents a methodological approach not identified by the authors in previous studies for conducting a Systematic Literature Review (joining a systematic search in academic databases with the use of the Connected Papers and Ryyan platforms). For academia, the study allowed for the identification of gaps in the body of scientific knowledge about the topics "technology acceptance model," "teaching-learning," and "pandemic COVID-19) The identification of gaps in the literature allows for targeted studies with greater contribution to the existing body of scientific knowledge.
