Distortional buckling of simple lipped channel in bending results of the experimental analysis versus direct strength methods
(2006-12-01)
Cold-formed steel members are subject to failure caused by buckling, normally under loads smaller than those corresponding to partial or total yielding of the cross section. The buckling of members in bending can be ...
Multielemental evaluation of garbage bags by EDXRF
(Taylor & Francis Ltd, 2014-09-02)
Garbage bags have been broadly used for collecting household waste in Brazil and worldwide. Many of these bags are made from recycled polymers, and the presence of harmful elements is a matter of concern. In this study, ...
Experimental Analysis in Alternate Current and Direct Current of the Operating Parameters of a Universal Single-Phase Engine
(Universidad Nacional Tecnológica de Lima Sur, 2019)
This article presents the experimental analysis of a rotary machine, Universal Motor Analysis; analysis that obeys the purpose of obtaining the almost perfect understanding of the electromechanical behavior of said unit ...
Directional wavelets and a wavelet variogram for two-dimensional data
(2009)
This paper describes two new approaches that can be used to compute the two-dimensional experimental wavelet variogram. They are based on an extension from earlier work in one dimension. The methods are powerful 2D ...
