1. Finite strip method computer application for buckling analysis of thin-walled structures with arbitrary cross-sections
Abstract The Direct Strength Method (DSM) is a well-known formulation presented in the Brazilian standard ABNT NBR 14762:2010, that estimates the strength capacity of cold-formed steel (CFS) members. However, this formulation requires the elastic critical buckling loads as point of departure, regarding local (L), distortional (D) and global (G) modes, which

3. ANÁLISE GRÁFICA DO DESEMPENHO DE MÉTODOS COMPUTACIONAIS NO ESTUDO DE PROPRIEDADES TERMOQUÍMICAS
In this manuscript we have evaluated the computational methods performance in the calculation of thermochemical properties using graphical analysis. The analysis was carried out in a set of 74 organic molecules considering the following thermochemical properties: standard enthalpy of formation, ionization energy and electron and proton affinities. The evalua

4. Visual FTBL Generator: Visual Generation Tool for 13C-FLUX File
Abstract 13C metabolic flux analysis (13C-MFA) has achieved increasing significance in quantitative metabolic system analysis in recent years. In 13C metabolic flux analysis, 13C-FLUX software is a major analytical tool. The software’s input script is primarily expressed in textual form without visual presentation of the structure of the entire metabolic

6. Silver nanoparticles incorporated PVC films: evaluation of structural, thermal, dielectric and catalytic properties
Abstract In this work, silver nanoparticle – polyvinylchloride (SNC-PVC) composites were synthesized by loading 2.5% to 10.0% silver ions to PVC using simple solution casting technique. Material properties including dielectric, thermal stability were discussed in some detail. Incorporation of silver nanoparticles (SNPs) in the PVC matrix was confirmed by U

10. Partial Volume Prediction Through Nonlinear Mixed Modeling
ABSTRACT The objective of this study was to assess the prediction of partial volumes with nonlinear mixed modeling for Pinus taeda. The volume of 558 trees was measured. The four-parameter logistic model was used in its modified form for the nonlinear mixed approach and, for comparison, the 5th degree polynomial was used. In the mixed modeling, the random ef

12. GRAPHICAL REPRESENTATION ANALYSIS OF COMPLEMENTARY CIVIL PROJECTS USING "CAD 2D", "BIM" AND "RA" AND IDENTIFICATION OF INTERFERENCES
Abstract Technical graphic representation presents problems concerning the reduction of dimensionality from 3D to 2D. AEC (architecture, engineering and construction) projects usually adopt the top view paradigm with two-dimensional orthogonal projection. Recently, three major changes in technical representation were the alteration of orthogonal projection i
