Study Notes

Civil Engineering

  • A structure in civil engineering refers to a system of interconnected members used to support loads.

Structural Design

  • During the preliminary structural design stage, the axial load, bending moment, and shear force are estimated.

Structural Analysis

  • Structural analysis establishes the internal forces and stresses in the structure.

Determining Member Size

  • The purpose of determining the size of interconnected members in structural design is to ensure the structure can withstand the estimated loads.

Prediction of Structural Analysis

  • The prediction of structural analysis is based on the estimated loads, material properties, and structural geometry.

Enhancing Figure of Merit (FOM) in Au Thin Film

  • The technique used to achieve an enhanced figure of merit (FOM) in the wedge-shaped Au thin film is not specified in the given text.

Definition of Figure of Merit (FOM)

  • The figure of merit (FOM) is defined as the ratio of the sensor's sensitivity to its intrinsic noise.

Fabrication of Wedge-Shaped Au Thin Film

  • The wedge-shaped Au thin film was fabricated through a process not specified in the given text.

Surface Plasmon Resonance (SPR) Transducers
