Emotion representations are psychological constructs for modelling, analysing, and recognising emotion, being one essential element of affect. Due to its complexity, the boundaries between different emotion concepts are often fuzzy, which is also reflected in the diversification of emotion databases, and their inconsistent target labels. When facing data scarcity as an ever present issue for acoustic...
Buoyancy correction of air for weight volume is very important in the mass measurement. Traditional hydrostatic method for measuring weight volume is the most accurate method currently, but it is a complicated process requiring the weight to be wetted in a reference fluid. To eliminate the influence of liquid against weight mass in the determination of weight volume of the hydrostatic method, the...
A lot of cutting fluid in metal cutting process causes environmental pollution and increases the manufacturing cost. Control of cutting fluid is one of the serious problems that the modern manufacturing technology faces with. This paper describes in brief the development tendency of cutting fluid and its limitations. The mechanism about pulse waveform generated by ultrasonic vibration cutter is studied,...
The ultrasonic torsional vibration acoustic system is devised. The system consists of a ultrasonic generator, two longitudinal transducer, two longitudinal horn, a reverse horn and bearing components. It is of the vibration frequency 20.7 KHz and ultrasonic vibration amplitude 15 μm. The system is installed in the Lathe Slide to boring the precision deep hole. Ultrasonic generator has been improved...
A new system for studying electrical properties of cell suspension is presented, which is based on the piezoelectric pressure wave propagation (Piezo-PWP) method. Because of the introduction of ultrasound to the system, the biological effects of ultrasound must be considered. In the experiment, the most important impact of the ultrasound is the steady-state cavitation. Under the exposure to the ultrasound,...
A new system for measuring charge of the cell suspension is presented, which is based on the piezoelectric pressure wave propagation method (Piezo-PWP). According to charge characters of the cell suspension, the principle of this system, the design of electrodes and the cavity structure are introduced. The piezoelectric ceramics PbZrTiO3 (PZT) and the piezoelectric polyvinylidene fluoride (PVDF) film...
