- Artigo de eventoMultivariate Analysis of SERS Signals for Multianalyte Detection in Co3O4-Ag SubstratesTieppo K.; Fonsaca J.E.S.; Martins K.S.B.; Teixeira W.S.R.; de Matos C.J.S. (2023)© Optica Publishing Group 2023, © 2023 The Authors.We propose a new SERS substrate based on a Co3O4-Ag nanocomposite and employ it to detect two different chemical species. Multivariate analysis is then used to individually identify the presence of each species.
- Artigo de eventoImage Processing of Antibody Detection using Machine Learning for an Optical Bio-sensing ApplicationTieppo B.; Vale D.L.; Fonsaca J.E.S.; Rehan M.; Megid J.; Teixeira W.S.R.; Grasseschi D.; de Matos C.J.S.; Saito L.A.M. (2023)© Optica Publishing Group 2023, © 2023 The Authors.We propose images processing recorded with a waveguide sensor of an immunological test based on antigen-antibody reaction. Machine Learning combining optical detection identifies bovine brucellosis antibodies and can be useful for other immunoassays.
- ArtigoInvestigation of Lateral Stability of UHPC Beams Supported by Bearing Pads Considering the Nonlinear Lift-Off EffectCosta L.O.; Krahl P.A.; De Lima M.C.V. (2023)© 2022 American Society of Civil Engineers.Ultrahigh-performance concrete (UHPC) is an advanced cement-based material with a compressive strength greater than 150 MPa. The application of UHPC on prestressed girders allows the design of very long spans with thin sections. However, the increased slenderness, low lateral flexural stiffness, flexible supports, and beam imperfections make lateral instability critical. Therefore, this paper presents an analytical prediction of precast beams' behaviors considering the nonlinear contact interaction with the bearing pads. The nonlinear geometric theory for the slender element is coupled with the nonlinear contact mechanism developed between the beam and pad through the energy approach. The proposed solutions are compared with the equations available in the literature that consider the linear stiffness contact interaction. Changes in the limit load of up to 84% were a result of the lift-off effect (contact interaction). From the results, the UHPC is highly sensitive to lateral instability, giving a maximum load/dead weight ratio of up to 1.08 where the common technical recommendation is greater than four.
