in this study, generation of the transient evoked ooacoustic emissions in human ear has been simulated using a new electroacoustic model. the method of state variables was adopted to calculate the auditory model, and numerical integration methods have been used to solve differential equations in matlab. simulation results have been compared with the real data. in this study, latency curves, fre...

clinical pharmacy is deemed an integral component of a health care system. the presence of clinical pharmacists in medical rounds could assist physicians in optimizing patients' pharmacotherapy. moreover, clinical pharmacists may reduce adverse effects and medication errors insofar as they contribute significantly to the detection and management of drug-related problems, not least in patients w...

A new heterodyne nano-displacement with error reduction is presented. The main errors affecting the displacement accuracy of the nano-displacement measurement system including intermodulation distortion error, cross-talk error, cross-polarization error and phase detection error are calculated. In the designed system, a He-Ne laser having three-longitudinal-mode is considered as the stabiliz...

Accuracy of inertial navigation system (INS) is limited by inertial sensors imperfections. Before using inertial sensors signals in the data fusion algorithm, noise removal method should be performed, in which, wavelet decomposition method is used. In this method the raw data is decomposed into high and low frequency data sets. In this study, wavelet multi-level resolution analysis (WMRA) techn...
