From digitalization to cybernization : Delivering value with cybernized services
2019
This reflection note, based on the lead author’s keynote presentation at the Information Systems Research Seminar in Scandinavia/Scandinavian Conference on Information Systems 2019, makes an argument for the need to study the transformation from digital services to cybernized services offered by service providers to their customers. We first discuss the digitalization of services. Then, we argue that the emergence of cyber-physical systems enables a new kind of services that apply; e.g.; the internet of things, analytics of sensor-based big data, and artificial intelligence for value creation. In other words, the cybernization of services. We illustrate two particular approaches for underst…
All-sky search for continuous gravitational waves from isolated neutron stars using Advanced LIGO O2 data
2019
We present results of an all-sky search for continuous gravitational waves (CWs), which can be produced by fast-spinning neutron stars with an asymmetry around their rotation axis, using data from the second observing run of the Advanced LIGO detectors. We employ three different semi-coherent methods ($\textit{FrequencyHough}$, $\textit{SkyHough}$, and $\textit{Time-Domain $\mathcal{F}$-statistic}$) to search in a gravitational-wave frequency band from 20 to 1922 Hz and a first frequency derivative from $-1\times10^{-8}$ to $2\times10^{-9}$ Hz/s. None of these searches has found clear evidence for a CW signal, so we present upper limits on the gravitational-wave strain amplitude $h_0$ (the …
