Shape matching is a popular method for simulating deformable objects in real time as it is fast and stable at large time steps. Although shape matching can simulate large elastic deformation and ductile fracturing, until now, they are limited to scenarios with relatively small plastic deformation. In this work, we present a method for simulating deformable solids undergoing large plastic deform...

This Paper presents improvements done to a Programming by Demonstration(PbD)system in order to handle complex one and two hand manipulations. In order to do this, functional roles were added to the systems knowledge base. According to them a probability density function expressing the relationship between the manipulated objects has been set up. Since one object can fulfill several functional r...

We present a visual language that serves as a novel form of feedback in a Programming by Demonstration (PBD) interface. The language explicitly represents data, such as les, with unique icons and implicitly represents operations by changes to data icons, so that operations reeect the changes seen in the interface when executed. In addition, the language is used to provide feedback to the user b...

We report the first experimental demonstration of a humidity insensitive polymer optical fiber Bragg grating (FBG), as well as the first FBG recorded in a TOPAS polymer optical fiber in the important low loss 850 nm spectral region. For the demonstration we have fabricated FBGs with resonance wavelength around 850 nm and 1550 nm in single-mode microstructured polymer optical fibers made of TOPA...

a new intelligent photovoltaic (PV) panel structure to extract the maximum power in mismatch irradiance is proposed. In conventional structures, difference of irradiance between series panels can cause the deviation of maximum power point. In this condition tracking MPP becomes difficult and reduces efficiency. Improvements in power electronics and its effects in PV industrial technology, devel...

We present a framework for learning skills from novel types of demonstrations that have been shown to be desirable from a human-robot interaction perspective. Our approach –Keyframe-based Learning from Demonstration (KLfD)– takes demonstrations that consist of keyframes; a sparse set of points in the state space that produces the intended skill when visited in sequence. The conventional type of...

We report the demonstration of two-dimensional electro-optic imaging using continuous-wave THz radiation. Two single-frequency laser diodes serve as the optical source for both the generation and detection processes. The generation process occurs by mixing in a photoconductive emitter, while the detection process utilizes an electro-optic crystal and charge coupled device camera. The method per...
