The present paper considers the composite plate resting on an elastic pinned subjected to harmonic loads. The plate element model with high-order shear deformation theory and finite element algorithm is proposed in order to buckling analysis of the plate. As a result, the buckling domain is determined. Moreover, the effect of geometric parameters, elastic pins, and materials on the buckling of the plate is comprehensively investigated.

A novel frequency domain assurance criterion, called hereby Spectral Assurance Criterion (SAC), is proposed for frequency response analysis of cracked piezoelectric beam under moving load. First, a model of cracked beam bonded with a piezoelectric layer under moving harmonic load is conducted based on the double beam conception and then, analytical expressions of midspan beam deflection (mechanical response) and output charge produced in the piezoelectric layer (electric response) has been established in the frequency domain.

The 2-methyl-4-nitroaniline (NA) was converted into the raw material N-benzyl-2-methyl-4-nitroaniline (BNA), and the solubility of BNA in various organic solvents was calculated gravimetrically. BNA’s solubility and crystal structure make it an excellent solvent for the low-temperature solution growth method used to create single crystals of BNA with orthorhombic structure studied through single crystal analysis.

This paper will figure out the effects of stator and rotor pole to average torque and harmonic torque of the SRM three phase 6/4 30kW, 3000 rpm. Based on this analysis, it is possible to choose the stator pole angle and rotor pole angle values that best suit the SRM 6/4 structure to minimize torque undulation and maximize the average moment.

Ebook "Music theory for musical theatre" is a textbook designed to demystify music theory and analysis to make it more accessible to the musical theatre student. It aims to equip the student with a basic skill set that he or she can directly apply to the art form. John Bell and Steven R. Chicurel explore how musical theatre composers use basic principles of music theory to help illuminate characters and tell stories, while helping the student understand the form, structure, and dramatic power of musical theatre repertoire.
