Calculation of crosstalks in multiple-conductor cables
The rigorous method of calculations of characteristics of two-wire lines (twisted pairs) inside the metal armor and of a mutual coupling between lines is considered. It is shown that the mutual coupling between lines in multiple-conductor cables results in appearance of electromagnetic interferences (crosstalks) in communication channels. The voltages values (interferences) across the impedances placed at the beginning and the end of the adjacent line at the given power in the main line are determined.
Cophasal Currents and Losses in Multiple-Conductor Cables
The rigorous method of calculations of characteristics of two-wire lines (twisted pairs) inside the metal armor is generalized in case of multiple-conductor cables with losses. On the basis of offered method it is shown that the asymmetry of excitation and loads results in appearance of cophasal currents (common wave) in lines. The effect of loads connected between wires and armor is considered.
Looking for regional words in late seventeenth-century England: Bishop White Kennett and his glossary to Parochial Antiquities (1695) 1
The analysis of regional dialects in the Early Modern period has commonly been disregarded in favour of an ample scholarly interest in the ‘authorised’ version of English which came to be eventually established as a standard. The history of regional ‘Englishes’ at this time still remains to a very great extent in oblivion, owing mainly to an apparent dearth of direct textual evidence which might provide trustworthy data. Research in this field has been for the most part focused on phonological, orthographical and morphological traits by virtue of the rather more abundant information that dialect testimonies yield about them. Regional lexical diversity has, on the contrary, deserved no special attention as uncertainty arises with regard to what was provincially restricted and what was not. This paper endeavours to offer additional data to the gloomy lexical setting of Early Modern regional English. It is our aim to give a descriptive account of the dialect words collated by Bishop White Kennett’s glossary to Parochial Antiquities (1695). This underutilised specimen does actually widen the information furnished by other well known canonical word-lists and provides concrete geographical data that might contribute to bridging the gaps still existing in the history of lexical provincialisms at the time.
