We report the results of an investigation, performed with the ISO spectrometers (LWS and SWS), on the star forming region associated with the Herbig-Haro objects HH 24–25 and 26. Low-resolution LWS spectra (45-197 μm) were observed towards the HH24MMS, HH25MMS and HH26IR sources as well as the HH26IR outflow. In addition, SWS scans of the pure H2 rotational lines towards HH24MMS were acquired. ...

Adaptive mechanisms are needed for achieving user anonymization and providing sufficient level of user anonymity due to the constant changes in underlying topology, mobility patterns and density of users and their queries. This paper describes a novel flexible and adaptive...
