Quantitative non-contact dynamic Casimir force measurements [PDF]
We show that the Casimir force gradient can be quantitatively measured with no contact involved. Results of the Casimir force measurement with systematic uncertainty of 3% are presented for the distance range of 100-600 nm. The statistical uncertainty is shown to be due to the thermal fluctuations of the force probe.

The surface wear in mechanical contacts under running conditions is always a challenge to quantify. However, the inevitable relationship between the airborne noise and the surface wear can be used to predict the latter with good accuracy.

Non-Contact Speed Measurement—a Comparison of Optical Systems
Four different optical methods of speed measurement for moving surfaces are considered, two using incoherent light and two using coherent laser light. These systems are described as spatial filters acting on the Wiener spectrum of the moving surface. For

Qubit measurement using a quantum point contact with a quantum Langevin equation approach [PDF]
We employ a quantum Langevin equation approach to establish non-Markovian dynamical equations, on a fully microscopic basis, to investigate the measurement of the state of a coupled quantum dot qubit by a nearby quantum point contact.

A Non-Contacted Height Measurement Method in Two-Dimensional Space
Height is an important health parameter employed across domains, including healthcare, aesthetics, and athletics. Numerous non-contact methods for height measurement exist; however, most are limited to assessing height in an upright posture.

Soil water retention behaviour for an instrumented embankment
Measurement of soil suction is important as soil suction is one of the two stress-state variables that control both the hydro and mechanical behaviour of unsaturated soils. One of the soil suction measurement techniques is the filter paper method.
