Note: A method for estimating the resolution of nanopositioning systems

Note: a method for estimating the resolution of nanopositioning systems.

This Note describes a new technique for estimating the resolution of nanopositioning systems. By recording the voltage applied to an actuator and performing a filtering operation, the position noise and resolution can be estimated. This technique is simple to apply in practice and does not require any additional sensors or specialized equipment.

Time Domain Resolution of Nanopositioning Systems

In this article, the resolution of a nanopositioning system is defined as the smallest distance between two non-overlapping points. Techniques are then described for estimating the closed-loop resolution from time-domain recordings of the contributing noise sources. Practical guidelines are also discussed to ensure statistically valid estimates. Experimental results show that the resolution of ...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

A Branch and Bound Method for Finding Flow Path Designing of Agv Systems (RESEARCH NOTE)

One of the important factor in the design of automated guided vehicle systems (AGVS) is the flow path design. This paper presents a branch-and-bound algorithm to determining the flow path by considering not only loaded-vehicles, but also empty-vehicles. The objective is to find the flow path, which will minimize total travel of loaded vehicles. We know that in branch-and-bound method a branch c...
