Recommendation application for video head impulse test based on fuzzy logic control

Vestibulo-ocular reflex(VOR) is an important biological reflex that controls eye movement to ensure clear vision while the head is in motion.Nowadays,VOR measurement is commonly done with a video head impulse test based on a velocity gain algorithm or a position gain algorithm,in which velocity gain is a VOR calculation on head and eye velocity,whereas position gain is calculated from head and eye position.The aim of this work is first to compare the two algorithms' performance and to detect covert catch-up saccade,then to propose a stand-alone recommendation application for the patient's diagnosis.In the first experiment,for ipsilesional and contralesional sides,the calculated position gain(0.94±0.17) is higher than velocity gain(0.84±0.19).Moreover,gain asymmetry of both lesion and intact sides using velocity gain is mostly higher than that from using position gain(four out of five subjects).Consequently,for subjects who have unilateral vestibular neuritis diagnosed from clinical symptoms and a vestibular function test,vestibular weakness is depicted by velocity gain much better than by position gain.Covert catch-up saccade and position gain then are used as inputs for recommendation applications.

Short Baseline Positioning with an Improved Time Reversal Technique in a Multi-path Channel

The existence of a multi-path channel under the water greatly decreases the accuracy of the short baseline positioning system.In this paper,the application of a time reversal mirror to the short baseline positioning system was investigated.The time reversal mirror technique allowed the acoustic signal to better focus in an unknown environment,which effectively reduced the expansion of multi-path acoustic signals as well as improved the signal focusing.The signal-to-noise ratio（SNR） of the time reversal operator greatly increased and could be obtained by ensonifying the water.The technique was less affected by the environment and therefore more applicable to a complex shallow water environment.Numerical simulations and pool experiments were used to demonstrate the efficiency of this technique.

An empirical study of the influence of the concept of“job-hunting”on graduates’employment

The concept of job-hunting is an important factor affecting university students’employment.This empirical study shows that while hunting for a job,graduates witness negative correlation between their expectation of the nature of work and the demand for occupational types and the accessibility to a post and monthly income;positive correlation between students’initiative and employment opportunities;positive correlation between salary expectation and real income;negative correlation between mental preparation for hardship and job satisfaction.Therefore,institutions of higher learning must strengthen their employment education,guiding students to foster a sound sense of competition,the concept of occupational position,mental preparation for vocational hardship so that students can rectify their attitude towards employment and adjust their employment concept,thus benefiting them in gaining a position.
