Inductive localization accuracy of a passive 3-D coil in an Industry 4.0 environment [PDF]

open access: yesJournal of Sensors and Sensor Systems, 2019
In this paper a localization system of a passive 3-D coil is proposed and signal uncertainties due to the 3-D coil's arbitrary orientation are analyzed. The 3-D coil is excited by an alternating primary magnetic field.

Routine phasing of coiled-coil protein crystal structures with AMPLE

open access: yesIUCrJ, 2015
Coiled-coil protein folds are among the most abundant in nature. These folds consist of long wound α-helices and are architecturally simple, but paradoxically their crystallographic structures are notoriously difficult to solve with molecular-replacement

Coarse-graining protein energetics in sequence variables

open access: yes, 2005
We show that cluster expansions (CE), previously used to model solid-state materials with binary or ternary configurational disorder, can be extended to the protein design problem. We present a generalized CE framework, in which properties such as energy

Local Subspace-Based Outlier Detection using Global Neighbourhoods

open access: yes, 2016
Outlier detection in high-dimensional data is a challenging yet important task, as it has applications in, e.g., fraud detection and quality control. State-of-the-art density-based algorithms perform well because they 1) take the local neighbourhoods of ...

China Seismo-Electromagnetic Satellite search coil magnetometer data and initial results

open access: yesEarth and Planetary Physics, 2018
Four levels of the data from the search coil magnetometer (SCM) onboard the China Seismo-Electromagnetic Satellite (CSES) are defined and described. The data in different levels all contain three components of the waveform and/or spectrum of the induced ...
