Investigation of a mutual interaction force at different pressure amplitudes in sulfuric acid

Chinese Physics B 2011年第8期20卷 454-459页

作者： Nastaran Rezaee Rasoul Sadighi-Bonabi Mona Mirheydari homa.Ebrahimi Department of Physics Sharif University of Technology11365-91TehranIran Department of Physics Islamic Azad University Central Tehran BranchTehranIran

This paper investiages the secondary Bjerknes force for two oscillating bubbles in various pressure amplitudes in a concentration of 95% sulfuric acid. The equilibrium radii of the bubbles are assumed to be smaller than 10 μm at a frequency of 37 kHz in various strong driving acoustical fields around 2.0 bars （1 bar=10^5 Pa）. The secondary Bjerknes force is investigated in uncoupled and coupled states between the bubbles, with regard to the quasi-adiabatic model for the bubble interior. It finds that the value of the secondary Bjerknes force depends on the driven pressure of sulfuric acid and its amount would be increased by liquid pressure amplitude enhancement. The results show that the repulsion area of the interaction force would be increased by increasing the driven pressure because of nonlinear oscillation of bubbles.

An important factor in the course of daily medical diagnosis and treatment is understanding patients’ emotional states by the caregiver physicians. However, patients usually avoid speaking out their emotions when expressing their somatic symptoms and complaints to their non-psychiatrist doctor. On the other hand, clinicians usually lack the required expertise(or time) and have a deficit in mining various verbal and non-verbal emotional signals of the patients. As a result, in many cases, there is an emotion recognition barrier between the clinician and the patients making all patients seem the same except for their different somatic symptoms. In particular, we aim to identify and combine three major disciplines(psychology, linguistics, and data science) approaches for detecting emotions from verbal communication and propose an integrated solution for emotion recognition support. Such a platform may give emotional guides and indices to the clinician based on verbal communication at the consultation time.

A unique circular path of moving single bubble sonoluminescence in water

Chinese Physics B 2011年第7期20卷 252-258页

作者： Rasoul Sadighi-Bonabi Mona Mirheydari homa.Ebrahimi Nastaran Rezaee Lida Nikzad Department of Physics Sharif University of TechnologyTehran 11365-91Iran Department of Physics Islamic Azad University Central Tehran BranchTehran 14676-86831Iran Laser and Optics Research School Tehran 14676-86831Iran

Based on a quasi-adiabatic model, the parameters of the bubble interior for a moving single bubble sonoluminescence （m-SBSL） in water are calculated. By using a complete form of the hydrodynamic force, a unique circular path for the m-SBSL in water is obtained. The effect of the ambient pressure variation on the bubble trajectory is also investigated. It is concluded that as the ambient pressure increases, the bubble moves along a circular path with a larger radius and all bubble parameters, such as gas pressure, interior temperature and light intensity, increase. A comparison is made between the parameters of the moving bubble in water and those in N-methylformamide. With fluid viscosity increasing, the circular path changes into an elliptic form and the light intensity increases.
