Distance measures for embedded graphs [PDF]

open access: yesComputational Geometry, 2021
We introduce new distance measures for comparing straight-line embedded graphs based on the Fréchet distance and the weak Fréchet distance. These graph distances are defined using continuous mappings and thus take the combinatorial structure as well as the geometric embeddings of the graphs into account.

Site Selective and Efficient Spin Labeling of Proteins with a Maleimide-Functionalized Trityl Radical for Pulsed Dipolar EPR Spectroscopy

open access: yesMolecules, 2019
Pulsed dipolar electron paramagnetic resonance spectroscopy (PDS) in combination with site-directed spin labeling (SDSL) of proteins and oligonucleotides is a powerful tool in structural biology.

Kompariranje in kalibriranje elektronskih tahimetrov : Comparison and Calibration of Electronic Distance Meters [PDF]

open access: yesGeodetski Vestnik, 2003
All measuring instruments are subject to errors. Due to their characteristics random errors cannot be influenced and with instrument calibration they cannot be eliminated.

An Ultrasonic Sensor for Distance Measurement in Automotive Applications [PDF]

open access: yes, 2001
This paper describes an ultrasonic sensor that is able to measure the distance from the ground of selected points of a motor vehicle. The sensor is based on the measurement of the time of flight of an ultrasonic pulse, which is reflected by the ground. A

Can molecular motors drive distance measurements in injured neurons? [PDF]

open access: yesPLoS Computational Biology, 2009
Injury to nerve axons induces diverse responses in neuronal cell bodies, some of which are influenced by the distance from the site of injury. This suggests that neurons have the capacity to estimate the distance of the injury site from their cell body ...
