Residual biomass from surfactin production is a source of arginase and adsorbed surfactin that is useful for environmental remediation
Lipopeptides are important secondary metabolites produced by microbes. They find applications in environmental decontamination and in the chemical, pharmaceutical and food industries. However, their production is expensive. ... -
Determination of viscosity and solids in pressure-sensitive adhesives by FTIR-ATR and multivariate calibration
This paper presents the application of infrared spectroscopy in conjunction with chemometric methods for quality control in adhesive manufacturing. From 105 infrared spectra of pressuresensitive adhesive samples of different ... -
Determination of chlorophenol in environmental samples using a voltammetric biosensor based on hybrid nanocomposite
In this work, a simple electrochemical biosensor for 4-chlorophenol was developed based on laccase immobilized on a hybrid nanocomposite (ZnO nanoparticles/chitosan), and incorporated in a carbon paste electrode. There are ... -
Simultaneous determination of different phenolic compounds using electrochemical biosensor and multivariate calibration
Phenolic compounds are important environmental contaminants due to their high toxicity and persistence in the environment. The use of enzyme-based electrochemical biosensors is a simple, sensitive and low-cost alternative ... -
Quality control of commercial cocoa beans (Theobroma cacao L.) by near-infrared spectroscopy
This work presents the use of near-infrared (NIR) spectroscopy as a fast and eco-friendly alternative to the conventional methods currently used for the quality control of cocoa beans. A key feature of this study was that ... -
Optimization trends in total lipopeptide production by Bacillus velezensis revealed a sustainable submerged fermentation method using sweet potato peels
Lipopeptide of the surfactin family are very potent biosurfactants with important applications for environmental remediation and chemical industries. In the present work, the complex production of lipopeptide ... -
Fedclusterensemble: enhancing clustered federated learning through confidence-based ensembles and cyclic intra cluster client selection
(Elsevier BV, 2025)Federated Learning (FL) has emerged as a transformative paradigm for decentralized model training, enabling multiple clients to collaboratively learn without sharing sensitive data. However, FL’s performance is often ... -
Distributed egocentric betweenness measure as a vehicle selection mechanism in VANETs: a performance evaluation study
(MDPI AG, 2018)In the traditional approach for centrality measures, also known as sociocentric, a network node usually requires global knowledge of the network topology in order to evaluate its importance. Therefore, it becomes difficult ... -
Exploiting vehicular social networks and dynamic clustering to enhance urban mobility management
(MDPI AG, 2019)Transport authorities are employing advanced traffic management system (ATMS) to improve vehicular traffic management efficiency. ATMS currently uses intelligent traffic lights and sensors distributed along the roads to ... -
Using data augmentation techniques on dermoscopic images to improve the accuracy of the convolutional neural network
(Atena Editora Edição de Livros Ltda, 2025)Computer vision and machine learning techniques capable of assisting specialists in different areas in their day-to-day tasks are the subject of several studies. For example, in the area of health, there is the diagnostic ... -
ATRIP: architecture for traffic classification based on image processing
(MDPI AG, 2020)With the increase of vehicles in large urban centers, there is also an increase in the number of traffic jams and accidents on public roads. The development of a proper Intelligent Transport System (ITS) could help to ... -
A two-context-aware approach for navigation: A case study for vehicular route recommendation
(Elsevier BV, 2025)In contemporary urban environments, route recommendation systems have become an indispensable tool in moving the population from large centers, serving as valuable resources for circumventing traffic congestion. Enhancing ... -
Sistema distribuído para gerenciamento de informação e distribuição de conhecimento em redes veiculares
(Sociedade Brasileira de Computação - SBC, 2018)Sabe-se que, em Sistemas de Transporte Inteligentes (STIs), a constante troca de informação entre os véıculos é de vital importância para prover serviços em um ambiente veicular. Tipicamente, os STIs fazem uso dessa prática ... -
