On closer inspection, the so-called iconic turn in recent media history is a multimodal turn. Media communication has not only been enriched by pictures but has turned from a text-medium into a multi-medium, i.e. into a complex system of different modes like design, colours, pictures, graphics, and typography. Along with the multimodal turn, the linear structure of media communication has become n
In this paper we study the propagation problem of a time harmonic electro- magnetic field inside a cavity filled with a generic bianisotropic medium. We define the concepts of eigenfrequencies and modes of the cavity and we prove their existence and countability. We extend, in this respect, the theory for the isotropic, homogeneous, lossless cavity.
Frequency modulation in ring VCOs is investigated. Primarily, the linearity of conversion from input voltage to output frequency is considered. Bulk-voltage control of the threshold voltage of the VCO transistors is found to be a very promising approach for applications in frequency /spl Delta//spl Sigma/ converters. Different approaches apply in presence of high supply voltages, when transistors

Due to increased susceptibility to soft errors in recent semiconductor technologies, techniques for detecting and recovering from errors are required. Roll-back Recovery with Checkpointing (RRC) is one well known technique that copes with soft errors by taking and storing checkpoints during execution of a job. Employing this technique, increases the average execution time (AET), i.e. the expected
Brain Talk had as its theme, different aspects of language processing in the brain. The contributions focussed on the importance of context for the neurocognitive processing of language and speech in various communicative situations. The present volume, the first in the Birgit Rausing Language program conference series, contains papers from the Brain talk conference. They have been grouped in to
The design of radio-frequency inductively-degenerated CMOS low-noise-amplifiers does not follow the guidelines for minimum noise figure. Nonetheless, state-of-the-art implementations achieve noise figure values very close to the theoretical minimum. In this brief contribution, we point out that this is due to the effect of the parasitic overlap capacitances in the MOS device acting as transconduct
