This paper presents a novel method for the attachment of a 1.8-nm Au nanoparticle (Au-NP) to the tip of an atomic force microscopy (AFM) probe through the application of a current-limited bias voltage. The resulting probe is capable of picking up individual objects at the sub-4-nm scale. We also discuss the mechanisms involved in the attachment of the Au-NP to the very apex of an AFM probe tip....

Through an experiment in a virtual environment, in this work we studied the relationship between vertical and horizontal shelf location and the frequency with which shoppers select items. We tested a random distribution hypothesis of the picking up frequencies (PUFs) in relationship to item shelf position within an experimental framework with various constant hypothesized confounding variables....

An efficient snake formulation should conform to the idea of picking the smoothest curve among all the shapes approximating an object of interest. In current geodesic snakes, the regularizing curvature also affects the convergence stage, hindering the latter at concave regions. In the present work, we make use of characteristic functions to define a novel geodesic formulation that decouples reg...

In this paper, dynamic behavior of nanoparticle motion during nanoprobe-based manipulation is investigated. Pushing, pulling or picking manipulation of the particles results in different behavior of rolling, sliding, sticking, or rotation. For a given point of contact of the nanoprobe tip on the particle, nanoprobe load magnitude and direction and critical frictional forces are obtained in all ...

Many VR applications require picking and moving of virtual objects. Many gesture based solutions do not work reliably, whereas controller based methods are not as natural as hand pose recognition. Tethered controllers add the issue of a cable being in the user’s way. We developed a gesture interface using a Leap Motion finger tracker attached to an Oculus Rift DK2 and implemented three ways of ...

A new first break picking for three-component (3C) vertical seismic profiling (VSP) data is proposed to improve the estimation accuracy of first arrivals, which adopts gesture detection calibration and polarization analysis based on the eigenvalue of the covariance matrix. This study aims at addressing the problem that calibration is required for VSP data using the azimuth and dip angle of geop...

This article describes the development of a mobile arm support for people with muscular diseases. The arm support is spring-balanced, with special attention on reduction of operating effort (high balancing quality and low friction), functionality (large range of motion), and aesthetics (inconspicuous design). The spring settings can be adjusted for wearing heavier clothing or picking up an obje...

A ledge is created hen the working length can no longer be negotiated nd the original pathway of the canal has been lost. xtension of the access cavity to provide unobstructed ccess to the root canals, precurving and not forcing nstruments, usin...

We developed a technique of picking up the liquid surface in a noncontact manner by a cw-laser radiation. The momentum change of light at the laser transmission through the air-liquid interface appears as the radiation pressure, which deforms the liquid surface into the shape determined by the balance between the Laplace force of the curved surface and the radiation pressure. The displacement o...

Wire harnesses are essential connecting components in manufacturing industry but challenging to be automated industrial tasks such as bin picking. They long, flexible and tend get entangled when randomly placed a bin. This makes it difficult for the robot grasp single one dense clutter. Besides, training or collecting data simulation is due difficulties modeling combination of deformable rigid ...
