The use of an instrumented scanning vehicle has become the center focus for bridge health monitoring (BHM) due to its cost efficiency, mobility, and practicality. However, indirect BHM still faces challenges such as effects road roughness on response, which can be avoided when is in a stationary condition. This paper proposes baseline-free method detect damage using vehicle. proposed implemente...

We present a heuristic approach to geometric path planning with movable obstacles. Treating movable obstacles as mobile robots leads to path planing problems with many degrees of freedom which are intractable. Our strategy avoids this computational complexity by decoupling the whole motion planning problem into a series of tractable problems, which are solved using known path planning algorithm...

A fuel-supply system using movable fuel-supply vehicles (FSVs) is proposed and its performance is evaluated. Both FSVs and vehicles requesting fuel are equipped with networked sensors. The sensors in FSVs are location sensors, and those in vehicles requesting fuel are for determining the remaining amount of fuel and the location of the vehicle. The time from when a fuel request is generated unt...

In this paper, nonlinear control techniques are developed to control parallel-plate micro electrostatic actuators in the presence of parasitics and parametric uncertainties. The movable plate of the micro actuator is actively controlled utilizing the measurements of internal charge and movable plate’s displacement. A velocity observer is designed to estimate the velocity of the plate that is ne...

Navigation Among Movable Obstacles Mike Stilman Robots would be much more useful if they could move obstacles out of the way. Traditional motion planning searches for collision free paths from a start to a goal. However, real world search and rescue, construction, home and nursing home domains contain debris, materials clutter, doors and objects that need to be moved by the robot. Theoretically...

OBJECTIVE The objective is evaluation of a traditionally designed operating room using simulation of various surgical workflows. BACKGROUND A literature search showed that there is no evidence for an optimal operating room layout regarding the position and size of an ultraclean ventilation (UCV) canopy with a separate preparation room for laying out instruments and in which patients are induc...

We present an integrated approach to modeling and control of electrostatically-actuated MEMS. The model consists of a set of fixed or movable electrodes, each coupled to the others through a resistor and capacitance, and to ground through a capacitance and a voltage or current source. This formulation incorporates movable structures, control electrodes, sense electrodes, and parasitic capacitan...

The indirect method of using a passing vehicle to identify modal properties girder bridge has become attractive recently. Compared the direct method, which requires lot sensors installed directly on itself, only single sensor indirectly measure response bridge. However, it is difficult eliminate adverse effect road surface roughness. An approach based blind source separation proposed for first ...

In this note, we give a Morse-type bigness criterion for the difference of two pseudoeffective (1, 1)-classes by using movable intersections. As an application, we give a Morse-type bigness criterion for the difference of two movable (n− 1, n− 1)-classes.
