This paper focuses on the modeling, control, and simulation of an over-actuated hexacopter tilt-rotor (HTR). This configuration implies that two of the six actuators are independently tilted using servomotors, which provide high maneuverability and reliability. This approach is predicted to maintain zero pitch throughout the trajectory and is expected to improve the aircraft’s steering accuracy. This arrangemen...
This work presents the control allocation and tuning methodology for an over-actuated Hexacopter Tilt-Rotor (HTR) designed for precision agriculture applications. The HTR's innovative design includes two independently tiltable rotors, enhancing stability and forward velocity, making it suitable for low-altitude maneuvers in agricultural environments. The study focuses on the implementation of a cascade Proporti...
This work presents an approach for detecting olive knot disease in olive trees, utilizing Computer Vision (CV), Unmanned Aerial Vehicle (UAV) based imagery, and Machine Learning (ML) within the context of Precision Agriculture (PA). The study focuses on applying the You Only Look Once (YOLO) deep learning architecture to develop a model capable of identifying trees affected by the disease with accuracy and spee...
Precision agriculture has emerged as a vital approach to modern agricultural management, addressing the dual challenge of increasing food production while preserving the environment. Its importance lies in its ability to leverage advanced technologies to optimize productivity, reduce waste, and ensure sustainability, particularly in high-value crops such as vineyards and olive groves. This study explores the ap...
Reconhecemos conhecimento da sociedade que desde os primórdios recursos naturais, como as plantas, são utilizados para suprir as necessidades dos homens, tanto alimentícia, como em cuidados com a saúde. Morinda citrifolia, está planta relacionada a diversas atividades biológicas, dentre elas a antibacteriana. O presente trabalho teve por objetivo analisar a atividade antibacteriana de extratos da folha, casca e...
Intestinal parasites are closely related to basic sanitary conditions, socioeconomic status, level of education, age and hygiene habits of the population; it is a serious Brazilian public health problem. This study aims to identify the prevalence of intestinal parasites in two municipalities of Zona da Mata, State of Minas Gerais, Brazil. We analyzed the samples using spontaneous sedimentation technique. In Viç...
A prevalência de parasitoses intestinais está intimamente relacionada com as condições de saneamento básico, situação socioeconômica, nível de educação, idade e hábitos de higiene da população, e continua sendo um grave problema de saúde pública no Brasil. Este estudo tem como objetivo principal identificar a prevalência dos parasitas intestinais em dois municípios da Zona da Mata do Estado de Minas Gerais, Bra...
One isolate of predator fungi Duddingtonia flagrans (AC001) was assessed in vitro regarding the capacity of supporting the passage through pigs' gastrointestinal tract without loss of the ability of preying infective larvae Oesophagostomum spp. Fungal isolates survived the passage and were efficient in preying L3 since the first 8 h of collection (p < 0.01) in relation to the control group (without fungus). Com...
Strongyloides venezuelensis tem sido utilizado como um modelo para estudo da estrongiloidose humana. O objetivo deste trabalho foi comparar a capacidade predatória dos fungos nematófagos Duddingtonia flagrans (AC001), Arthrobotrys robusta (I-31) e Monacrosporium sinense (SF53) sobre larvas infectantes (L3) de Strongyloides venezuelensis em condições laboratoriais no meio ágar-água 2%. Ao final do experimento, o...
O objetivo deste trabalho foi avaliar a atividade predatória do fungo Duddingtonia flagrans (AC001) sobre larvas infectantes de Ancylostoma ceylanicum após o trânsito gastrintestinal em hamsters. Foram utilizados vinte animais no experimento, divididos em dois grupos: um grupo tratado (10 animais) e um grupo controle (10 animais). No grupo tratado com D. flagrans, cada animal recebeu 5mg/25g de peso vivo de mic...
