BAU Journal - Science and Technology

SmBa2Cu3O7-δ /(ZnFe2O4)x superconducting composites with 0.00 ≤ x ≤ 0.20 wt% were prepared by the usual solid-state reaction method. The prepared samples were investigated using X-ray powder diffraction (XRD) at room temperature and electron paramagnetic resonance (EPR) measurements in the temperature range (100-295 K). It is found that EPR spectra are dominated by an anisotropic Cu2+ EPR pattern. Moreover, the EPR spectral intensity increases as the temperature decrease from room temperature down to 100 K. The number of spins (N) participating in EPR resonance, the activation energy (Ea), the paramagnetic susceptibility (c) and the effective magnetic moment (µeff) are calculated …

Implementing Bluebeam Software In Architectural Engineering Design Courses, Michael James Deigert, Anahid A. Behrouzi, Pamalee A. Brady

Architectural Engineering

A critical aspect of structural engineering education is helping students develop effective electronic graphical communication skills to convey their design solutions. Many undergraduate civil and architectural engineering programs address this at the document creation stage by teaching Autodesk AutoCAD or Revit to create 2-D or 3-D structural design files. However, students tend to have limited exposure to commercial software for document management and markup that allows for coordination between the engineer, architect, and contractor teams. Bluebeam Revu is one such software that has emerged as an industry standard for annotation and markup of engineering design documents.
