The simulator simulates, based on the tool input device information, an interaction between the simulated tool and simulated biological tissue. The simulator uses multiple computational threads, some of which provide their calculations to interrelated threads for use. The simulator displays a visual representation of the simulated interaction between the simulated tool and the simulated biological tissue and provides haptic feedback to the user. The threads may operate asynchronously and have different spatial and/or temporal resolutions. Threads may be selectively activated and deactivated. Threads may move their spatial coverage.Type: ApplicationFiled: January 14, 2010Publication date: July 15, 2010Applicant: SimQuest LLCInventors: Dwight Meglan, Albert Dvornik, Julien Lenoir, Paul S.

Publication number: 20100161298Abstract: A method for calculating a force acting on an interface between immiscible fluids in an SPH (Smoothed Particle Hydrodynamics) based fluid simulation includes: calculating a force caused by viscosities of the fluids; calculating a force caused by pressures of the fluids; calculating an external force applied to the fluids from outside; and calculating an interactive force caused by interaction between the fluids. The force acting on the interface between the immiscible fluids are obtained by using sum of the force caused by the viscosities, the force caused by the pressures, the external force and the interactive force. The interactive force is a surface tensional force calculated based on a pressure acting on the interface between the fluids.Type: ApplicationFiled: June 18, 2009Publication date: June 24, 2010Applicant: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Young Hee KIM, Bon Ki Koo

Publication number: 20100132450Abstract: Methods for optimizing petroleum reservoir analysis and sampling using a real-time component wherein heterogeneities in fluid properties exist. The methods help predict the recovery performance of oil such as, for example, heavy oil, which can be adversely impacted by fluid property gradients present in the reservoir. Additionally, the methods help optimize sampling schedules of the reservoir, which can reduce overall expense and increase sampling efficiency. The methods involve the use of analytical techniques for accurately predicting one or more fluid properties that are not in equilibrium in the reservoir. By evaluating the composition of downhole fluid samples taken from the reservoir using sensitive analytical techniques, an accurate base model of the fluid property of interest can be produced. With the base model in hand, real-time data can be obtained and compared to the base model in order to further define the fluid property of interest in the reservoir.Type: ApplicationFiled: November 23, 2009Publication date: June 3, 2010Inventors: Andrew E.
