Total harmonic distortion (THD) plays an important role in the performance of miniature loudspeakers used in mobile phones. Traditional nonlinear models fail to predict THD in the higher frequency domain. Significant discrepancies can be found between the prediction and measurement. In this study, an extended model considering nonlinear acoustic…[Read more]

Understanding invisible work, thus, leads us to consider different constitutive relevancies. In turn, these serve to specify established concepts in STS, such as ‘controversy,’ to better distinguish the day-to-day conduct of natural science from that of politics or law.Backgrounds and Aims Klebsiella pneumoniae represents the most common…[Read more]
