An artificial intelligence approach to palaeogeographic studies: a case study of the Late Ordovician brachiopods of Laurentia [PDF]
Journal of Stratigraphy and Sedimentology ResearchesAccording to the earliest hypothesis which was based on qualitative studies of the Late Ordovician brachiopod fauna, the younger and larger species of Hiscobeccus, which was one of the epicontinental brachiopod fauna of North America, evolved from the ...

Effectiveness of double cutout on lateral buckling analysis of fiber reinforced composites
Polymer Composites, Volume 45, Issue 12, Page 10880-10887, 20 August 2024.Lateral buckling test mechanism. Abstract Lateral buckling, an essential mechanical phenomenon observed in composite beams subjected to specific external loads and boundary conditions, is influenced by various factors including cutout dimension, shape, position, and beam thickness in woven fabric laminated composite cantilever beams.

Earthquake Spectra, Volume 40, Issue 3, Page 2179-2209, August 2024.Summarized in this article are the major findings from a detailed damage investigation of an instrumented ductile reinforced concrete moment frame building subjected to a design‐level earthquake. The building sustained widespread damage during the 2016 M‐7.8 Kaikoura earthquake and was subsequently demolished. Prior to demolition, the structural system

Progress in Photovoltaics: Research and Applications, Volume 32, Issue 7, Page 468-480, July 2024.This study analyzes the effect of spectral albedo on photovoltaic module measurements and system model predictions. We demonstrate how indoor photovoltaic measurements can be adjusted to account for albedo, and measure up to a 2% difference in short‐circuit current with spectral effects.

Analysis and Design of Cold-Formed Z Purlins
International Journal for Research in Applied Science and Engineering Technology, 2022 Abstract: Structures built by cold-formed segments of primary members secondary members and roof panels provide a different solution for a great variety of areas such as housing, storage, education, etc The design of cold-formed sections has obvious complexity in view of the buckling of sections vis-à-vis stress in the compression element, especially ...

OPTIMIZATION OF PURLINS CROSS-SECTION EXPOSED TO FIRE
Contemporary Theory and Practice in Construction<p>In practice, consideration of fire protection for structural elements mainly occurs after the adopted dimensions of sections. However, this procedure leads to not the most cost-effective solution in general. To find the optimal solution, it is necessary to apply one of the optimization methods.

Investigating Reinforced Concrete Beams with Web Opening under Static and Cyclic Loads
Journal of Engineering, Volume 2024, Issue 1, 2024.This study aims to investigate experimentally and theoretically the behavior of reinforced concrete beams with openings subjected to static and cyclic loads. The experimental program consists of testing eight specimens with a rectangular opening at the shear zone, two of the beams serve as a control beam (without openings) subjected to static and ...
