On Ageing of Insulation Materials and Systems: Some Thoughts and Comments

M. G. Danikas

ABSTRACT

Ageing has been and still is one of the major – if not the major – challenges regarding insulation systems and materials. The present paper goes through a brief description of some fundamental models of ageing and points out aspects that deserve to be further investigated. Factors that affect (or may affect) the ageing of insulations are discussed.

The Subtle Details of Combining the Arts of Antenna Design, Construction, and Measurement - The Radial Discone Paradigm -

N. I. Yannopoulou and P. E. Zimourtopoulos

ABSTRACT

In the past, after the encouraged results produced by the first author and published in her master thesis regarding in essence the discone antenna, we decided to cooperate for the complement and extension of her work in the definite way of completely revealing all the subtle details of the whole work we are doing in general, in order to successfully combine the separate arts of antenna design, antenna construction, and antenna measurement, taking this particular antenna just as a concrete paradigm of practical application. Now, we describe in this paper the aforementioned way of ours and present the good agreement between the related analytical, computational, and experimental results, that we achieved working in this very way.
