Future management needs of a "software-driven" science community
The work of astronomers is getting more complex and advanced as the progress
of computer development occurs. With improved computing capabilities and
increased data flow, more sophisticated software is required in order to
interpret, and fully exploit, astronomic data. However, it is not possible for
every astronomer to also be a software specialist. As history has shown, the
work of scientists always becomes increasingly specialised, and we here argue
in favour of another, at least partial, split between "programmers" and
"interpreters". In this presentation we outline our vision for a new approach
and symbiosis between software specialists and scientists, and present its
advantages along with a simple test case.Comment: 7 pages, 3 figures, as presented at SPIE Astronomical instrumentation

Directional antennas for wireless sensor networks
Directional antennas provide angle-of-arrival information, which can be used for localization and routing algorithms in wireless sensor networks. We briefly describe three classical, major types of antennas: 1) the Adcock-pair antenna, 2) the pseudo-Doppler antenna, and 3) the electronically switched parasitic element antenna. We have found the last type to be the most suitable for wireless sensor networks, and we present here the early design details and beam pattern measurements of a prototype antenna for the
2.4-GHz ISM band, the SPIDA: SICS Parasitic Interference Directional Antenna
