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.

Seven known compounds, including two neolignans, four lignans, and one flavane were isolated from the methanol extract of Pandanus tonkinenis fruits. Their structures were determined to be ficusal, vladinol F, medioresinol, syringaresinol, lariciresinol, secoisolariciresinol, and luteoliflavan by analysis of MS and NMR data as well as by comparison of their spectral data with those reported in the literature.

In this study, in order to investigate the error rate of seismic analysis methods (static equivalent, spectral and time history) in intermediate structures with irregularity of hardness, 4 5-story steel samples with dual flexural frame system and bracing with different states of irregularity in height in soft SAP software has been modeled. The results showed that the equivalent static analysis method always provides conservative and somewhat uneconomical values compared to other methods, so it can be said that for static buildings, equivalent static analysis is reliable.

Infrared spectral analysis of milk is cheap, fast, and accurate. Infrared light interacts with chemical bonds present inside the milk, which means that Fourier transform infrared milk spectra are a reflection of the chemical composition of milk. Heritability of Fourier transform infrared milk spectra has been analysed previously.
