Influence of Incubation Calls on Post-hatching Responses of Pheasant Chicks

Ring-necked Pheasant (Phasianus colchicus) chicks exposed to a hen incubation vocalization during the final week of incubation showed stronger attraction to feeding and caution calls than expected by chance when tested one, three and five days post-hatching. Control chicks incubated in silence did not differ from chance in response to the caution call. Largest differences between experimental a...

Techniques of Radio Astronomy

This chapter provides an overview of the techniques of radio astronomy. This study began in 1931 with Jansky’s discovery of emission from the cosmos, but the period of rapid progress began fifteen years later. From then to the present, the wavelength range expanded from a few meters to the sub-millimeters, the angular resolution increased from degrees to finer than milli arc seconds and the rec...

Cognitive Radio Techniques for M2M Environments

Machine to Machine (M2M) communications have been recently introduced as a viable paradigm for allowing low cost and efficient communications among devices mainly in an autonomous manner. Even if M2M protocols need dedicated resources, a new paradigm, called Cognitive M2M (CM2M) communications, has been recently considered exploiting cognitive/opportunistic radio communications. After having in...

Comparison of Downconversion Techniques for Software Radio

Software radio is an enabling technology for future radio transceivers, allowing the realisation of multimode, multiband, and reconfigurable base stations and terminals. This paper describes work comparing two suitable methods of downconverting RF signals to baseband, which may be used in software radios. These are direct conversion and bandpass sampling. The performance of each method is evalu...

Subspace Techniques for Radio-Astronomical Data Enhancement

Radio astronomical observations have very poor signal to noise ratios, unlike in other disciplines. On the other hand, it is possible to observe the object of interest for long time intervals as well as using a wider bandwidth. Traditionally, by averaging in time and in frequency, it has been possible to improve the signal to noise ratio of astronomical observations to improve the dynamic range...
