Developed the Electromagnetic Imaging during medical endoscopic procedure utilizing the shape sensing technology concept.The technology allows to see the real time virtual position/shape of the distal shaft of an endoscope, while the endoscope is manipulated by a physician during a procedure. This capability is achieved in a low electromagnetic field with sensors (inductance coils) placed in the scope that transmit position data to a processor via wire connections. The processor determines position of the sensors in 3D space, then transmits video information allowing a virtual image of the shaft to be displayed on a monitor.

Developed 3D anatomical Human Torso Model for investigating the interaction of flexible endoscopic device with soft tissue during Wet Lab studies. Anatomical model includes a shell that simulates abdominal cavity as well as an animal tissue that simulates human internal organs. A shell surrounds the animal tissue and supports it in a few different positions for variety of configurations. A few sensors are embedded into model to detect interaction forces, torques and position of endoscopic medical device during simulated procedure. The computer program generates feedback to provide a physician with warning signals about approaching a dangerous level of interaction which could cause real patient discomfort or potential injury. Additionally the Model allows to collect valuable data of physician / patient interaction during simulation of the above procedure. This work was awarded the 2005 Technical Excellence Award for "Colonoscope Wet Lab Colon Model". Endovations, Boston Scientific Corp., Watertown, MA, 2005.

Developed model of incompressible viscous flow through rectangular duct with variable boundary conditions. The two-dimensional unsteady incompressible, laminar fluid flow bounded by two transversally vibrating surfaces. Both surfaces are smooth and satisfy the Reynolds roughness criterion. Rectangular gap (~1 mm) is much smaller than characteristic duct length (~100 mm). No-slip conditions for all boundaries. Inflow boundary has steady flow with parabolic velocity profile (Piosselle distribution). Outflow boundary has pressure equal zero. Computed sets of 2-D Navier-Stokes equations . The numerical scheme employed to solve these equations based on the finite-volume approach.

Developed and modeled a piezo-crystal driven acoustic flow in controlling boundary layers. The PZT element excite the channel / duct around the flowing medium into resonance at high frequency, thus will a variation of the velocity profile within the channel / duct through acoustic wave interaction. Simple considerations show that the inducing by wall oscillating cross-stream flow in a straight pipe has the potential for velocity profile changes that the velocity near wall became larger than near the centerline. The prototype of PZT actuation systems was build and tested. Patent US 6,109,566 (R-4239).

Developed and modeled an active control of a new generation pantographs for high speed trains. It established the range of parameters, the type of pantograph design, the conditions of railroad. The 1st degree model was developed. It established that the control technology possibilities as active control are limited in this case, because of actuation time was compatible with character time of process.

Model of passive vibration driven oscillator (VDO) was considered as vibration driven one-dimensional, one mass type oscillator for pumping air in boundary layer. The membrane pump was described as discrete system, as spring-mass-dampered oscillator with mass located in the center of membrane. Model for several VDO, with assumption of performing the harmonic oscillations was calculated (Matlab, Mathcad).
