The wavelet transform has emerged over recent years as a powerful time-frequency analysis and signal coding tool favoured for the interrogation of complex nonstationary signals. Its application to biosignal processing has been at the forefront of these developments where it has been found particularly useful in the study of these, often problematic, signals: none more so than the ECG. In this r...

The paper surveys the domain of polar interrogation in the Uralic language family in a typological perspective. An overview of the ways in which polar interrogation is marked in the world’s languages is presented and the encoding of the domain in Uralic languages is examined against this background. All the major types of polar interrogative marking are found in the family. Polar interrogatives...

In this paper, RFID reader-to-reader interference is analyzed from the point of view of interrogation range. To evaluate RFID interference quantitatively, the new figure-of-merit, interrogation range reduction ratio (IRRR), is defined. In order to show the usefulness of IRRR, its value is calculated in various environments. Additionally, the calculated IRRR values are verified by measurements u...
