A time-domain chemical-recognition system for classifying gases and analyzing gas mixtures is presented. We analyze the free induction decay exhibited by gases excited by far-infrared (terahertz) pulses in the time domain, using digital signal-processing techniques. A simple geometric picture is used for the classif ication of the waveforms measured for… (More)
To fulfill the vision of the Future Internet a ubiquitous deployment of IPv6 is a necessity. The work presented in this paper combines networking technologies and mobile software application development to support interworking of mobile devices and smart objects. We report on the implementation of an Android IPv6 smartphone that interworks with Web-enabled… (More)
—The use of terahertz pulses for imaging has opened new possibilities for scientific and industrial applications in the terahertz frequency range. In this article, we describe the technology necessary to perform terahertz " Tray " imaging, novel imaging techniques, and commercial applications of Tray imaging .
A method for detection and identification of polar gases and gas mixtures based on the technique of tera-hertz time-domain spectroscopy is presented. This relatively new technology promises to be the first portable far-infrared spectrometer, providing a means for real-time spectroscopic measurements over a broad bandwidth up to several THz. The measured… (More)
The electricity grid is undergoing a radical transformation from a production-driven to a demand-driven energy delivery platform known as the smart grid. The integration of a large amount of renewable and distributed energy resources, together with new patterns of electricity production, accentuates the need for research in information and communication… (More)
Biology has often been used as a source of inspiration in computer science and engineering. Bioinspired principles have found their way into network node design and research due to the appealing analogies between biological systems and large networks of small sensors. This paper provides an overview of bioinspired principles and methods such as swarm… (More)
