Análise estatística do comportamento estrutural de vigas de concreto armado reforçadas com PRFC

Revista Mundi Engenharia, Tecnologia e Gestão (ISSN: 2525-4782), 2019
O presente trabalho consiste na análise estatística do comportamento estrutural de vigas reforçadas com PRFC (Polímeros Reforçados com Fibra de Carbono). Essa técnica é uma opção para reforço de elementos de concreto, já que os materiais compósitos de fibras de carbono são flexíveis, altamente resistentes e podem substituir com vantagens, em alguns ...

Breaking the cycle of socioeconomic disadvantage: Parental reflexivity and motivation for change

Family Relations, Volume 75, Issue 1, Page 535-554, February 2026.
Abstract Objective The goal was to deepen the understanding of parental reflexivity by examining the relationship between its components and their association with parental motivation to engage in interventions, while analyzing professionals' expectations and perceptions of families' progress, in socioeconomically disadvantaged contexts.

Pathogenic Characteristics of Shrimp Early Mortality Syndrome (EMS)‐Causing Vibrio parahaemolyticus: A Comparative Transcriptomic Study Suggests the Relationship Between Metabolic Fitness and Virulence Gene Expression

Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.
To understand the disease‐causing characteristics of Vibrio parahaemolyticus in shrimp EMS, this comparative gene expression study analysed pathogenic (AHPND 5HP and non‐AHPND 2HP) and non‐pathogenic (S02) strains. Pathogenic strains shared similar expression profiles, distinct from the non‐pathogen.

Hybrid precoding and combining design for millimeter-wave multi-user MIMO based on SVD [PDF]

, 2017
In this paper, we focus on the millimeter-wave multi-user multiple-input-multiple-output (mmWave MU-MIMO) systems and propose a low-complexity hybrid precoding and combining design, which is applicable to both fully-connected structures and sub-connected

Damage Identification in Large‐Scale Bridge Girders Using Output‐Only Modal Flexibility–Based Deflections and Span‐Similar Virtual Beam Models

Structural Control and Health Monitoring, Volume 2024, Issue 1, 2024.
Damage identification (DI) methods using changes in static and modal flexibility (MF)–based deflections are effective tools to assess the damage in beam‐like structures due to the explicit relationships between deflection change and stiffness reduction caused by damage.
