The rst overtone rotation-vibration transitions of SiO give rise to prominent bandheads in the wavelength range between 4.0 and 4:5 m. In order to study the behaviour of these features in AGB stars we observed the 3.94 to 4:12 m spectra for a sample of 23 oxygen-rich late-type variables. In contrast to the SRb objects, the Miras show a very large scatter of(More)
Industrial Control Systems (ICS) are a less obvious part of the Internet of Things with their own unique security challenges. We introduce the structure and components of typical ICS installations. We also provide an overview of a number of ICS security approaches. Contrasting these with a sampling of documented ICS security incidents highlights the(More)
