Accurate terrain estimation is critical for autonomous offroad navigation. Reconstruction of a three-dimensional (3D) surface allows rough and hilly ground to be represented, yielding faster driving and better planning and control. However, data from a 3D sensor samples the terrain unevenly, quickly becoming sparse at longer ranges and containing large voids because of occlusions and inclines. the proposed approach uses online kernel-based learning to estimate a continuous surface over the area of interest while providing upper and lower bounds on that surface. Unlike other approaches, visibility information is exploited to constrain the terrain surface and increase precision, and an efficient gradient-based optimization allows for realtime implementation. To model sensor noise over varying ranges, a non-stationary covariance function is adopted. Experimental results are presented for several datasets, including groundtruthed terrain and a large 3D stereo dataset.
One of the major limitations for Atomic Force Microscopy (AFM) based nanoparticle pushing is that AFM only has one sharp tip as the end-effector. the interaction force between the nanoparticle and the tip is applied t...

Lithuanian language vowel modelling is considered in the paper. A vowel is modelled by a sum of formants where a formant is expressed by a quasipolynomial function of the second order (a combination of a damped sinusoid and polynomial). A formant is generated as the response of a linear dynamic system with multiple poles to the unit impulses sequence. In order to get more natural sounding, each formant is excited separately using input impulses amplitude modulation. Modulation scenarios are chosen according to the real sound formant amplitude dynamics. An example of a vowel generated is compared with real sounds using audio testing.
