In this work, gold nanorods (AuNRs) with well-controlled aspect ratios were prepared using a modified seedgrowth method and covered by TiO2 layers through the hydrothermal reaction to improve stability. Integrating TiO2 with plasmonic rod-like gold nanoparticles could enhance their photo activity by the local surface plasmon resonance (LSPR) effect. AuNRs aspect ratios were controlled by varying the amount of seed solution, reducing agents, surfactant (CTAB), and titanium (IV) but oxide.

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.

Acoustic feedback is a major problem in openfit digital hearing aids, which significantly lowers the signal quality and limits the achievable maximum stable gain. Adaptive feedback cancellation (AFC) is a common and efficient approach, however, it introduces a biased estimate of the feedback path due to a high correlation between loudspeaker signal and the incoming signal, especially when the incoming signal is spectrally coloured, e.g., speech, music.
