Numerical analysis of the straightening process of thin plate structures by elastic FEM based on the inherent strain method
(2012-12)
Welding distortion is practically an expected feature in shipbuilding, with a few exceptions; when thick plates are used, for example. Nowadays, the trend is to use thinner plates in order to reduce weight, aiming to reduce ...
Effect of phase transformation onset temperature on residual stress in welded thin steel plates
(2008-12)
The effect of solid-state phase transformation at low temperature on residual stresses in butt welded ferritic thin steel plates has been examined employing a finite element (FE) code. An algorithm considering the solidstate ...
Analysis and prediction of welding distortion in complex structures using elastic finite element method
(2012-07)
The Elastic Finite Element Method based on the inherent strain theory is used to predict the welding distortion of ship structures. In addition, a method to predict welding distortion of complex structures by using elastic ...
A numerical study of parameters governing an inherent deformation database of plates formed by line heating
(2008-08)
As an overall strategy to improve the accuracy of the forming process, the authors pay attention to those factors which may influence the inherent deformation of plates formed by line heating. In order to identify those ...
Experimental research on the effects of water application on greenhouse gas emissions from beef cattle feedlots
(2014-04-30)
The effect of water application (e.g., through rainfall or sprinkler system) on emissions of greenhouse gases (GHGs), such as nitrous oxide (N2O), methane (CH4), and carbon dioxide (CO2), from pen surfaces of open-lot beef ...
Nitrous Oxide Fluxes from a Commercial Beef Cattle Feedlot in Kansas
(2014-03-10)
Emission of greenhouse gases, including nitrous oxide (N2O), from open beef cattle feedlots is becoming an environmental concern; however, research measuring emission rates of N2O from open beef cattle feedlots has been ...
Estilos digitales de estudiantes universitarios en C&T y aplicaciones didácticas de los SmartPhones en el salón de clases.
(2014-07-24)
La actividad universitaria incluye la difusión y la adquisición de datos e informaciones, diseminada en múltiples
bases de datos y en las más variadas posibilidades de acceso, gracias a la Internet. La inmersión de los ...
Cuadro de mando integral para el diseño y validación de instrumentos para valorar el desempeño académico de docentes
(2009-12-22)
La valoración de la labor docente es un pilar de la acreditación universitaria. En un momento, particularmente sensible relacionado a esta tendencia global y a la imagen que emerge de las
diferentes unidades académicas y ...
Remoção de íons de metais pesados com bentonitas modificadas
(1905-06-23)
O presente trabalho apresenta o desenvolvimento
de um material sorvente a partir de bentonitas brasileiras
modificadas quimicamente com o objetivo de aumentar sua
capacidade de sorção de metais pesados e seu valor
agregado. ...
The Balance Score Card for the Design and Validation Instrumens to Measure the Academic Teachers´s Achievement and Performance
(1905-07-04)
The evaluation of faculty work is critical for the university accreditation. Moreover, particularly sensitive to this related tendency of faculty work evaluation; it is necessary to go beyond the knowledge factor and ...
