Interactive Blow and Burst of Giant Soap Bubbles

Previous studies on virtual soap bubbles mainly focused on methods for visualizing the physical and geometrical properties of soap bubbles and paid little attention to the possible ways to enhance the interaction between the simulation and the user. In this paper, a user interaction-based giant soap bubble simulation system is proposed in which the free-form shape, size, and position of giant s...

Land Tenure

Farming in sub-Saharan Africa outside South Africa typically takes place on small plots cultivated by individuals. The land tenure system is often described as 'communal', meaning that land is owned by a kin-based or political group and that individuals obtain the right to cultivate through their membership in that group. If a generalization is possible about the process through which people ob...

Modified Profile Likelihood Inference and Interval Forecast of the Burst of Financial Bubbles

We present a detailed methodological study of the application of the modified profile likelihood method for the calibration of nonlinear financial models characterised by a large number of parameters. We apply the general approach to the Log-Periodic Power Law Singularity (LPPLS) model of financial bubbles. This model is particularly relevant because one of its parameters, the critical time tc ...

Modeling and experimental analysis of acoustic cavitation bubbles for Burst Wave Lithotripsy.

A combined modeling and experimental study of acoustic cavitation bubbles that are initiated by focused ultrasound waves is reported. Focused ultrasound waves of frequency 335 kHz and peak negative pressure 8 MPa are generated in a water tank by a piezoelectric transducer to initiate cavitation. The resulting pressure field is obtained by direct numerical simulation (DNS) and used to simulate s...
