based on the fact the manipulation of fine nanoclusters calls for more precise modeling, the aim of this paper is to conduct an atomistic investigation for interaction analysis of particle-substrate system for pushing and positioning purposes. in the present research, 2d molecular dynamics simulations have been used to investigate such behaviors. performing the planar simulations can provide a ...

abstract: application of atomic force microscope as a manipulator for pushing-based positioning of nano-particles has been of considerable interest during recent years. however a detailed modeling of the interaction forces and control on the afm tip is important for prosperous manipulation control, a reliable control of the afm tip position during the afm-based manipulation process is a main is...

Contact mechanics is related to the deformation study of solids that meet each other at one or more points. The physical and mathematical formulation of the problem is established upon the mechanics of materials and continuum mechanics and focuses on computations involving bodies with different characteristics in static or dynamic contact. Contact mechanics gives essential information for the s...

In this paper, a teleoperated nano scale object manipulation system is proposed, and requirements of such systems are defined. The system consists of a user interface utilizing visual and haptic displays (macro world), nano-manipulator, controller and sensors (nano world), and teleoperation control and rough to fine imaging and actuation tools (between macro and nano worlds). A home-made Atomic...

in this study, it was intended to investigate the persian native speakers’ perception of gerunds by three different elicitation techniques i.e., written, audio, and pictorial through translation. eighty intermediate learners of english were asked to select persian translation of the gerund formsin these elicitation techniques. they were asked to choose one option from a pair of written first la...

BACKGROUND Thoracic spine manipulation has become a popular alternative to local cervical manipulative therapy for mechanical neck pain. This study investigated the acute effects of single-level and multiple-level thoracic manipulations on chronic mechanical neck pain (CMNP). METHODS Forty-eight patients with CMNP were randomly allocated to single-level thoracic manipulation (STM) at T6-T7 or...

BACKGROUND Osteopathic manipulative treatment (OMT) and ultrasound physical therapy (UPT) are commonly used for chronic low back pain. Although there is evidence from a systematic review and meta-analysis that OMT generally reduces low back pain, there are no large clinical trials that specifically assess OMT efficacy in chronic low back pain. Similarly, there is a lack of evidence involving UP...
