In this paper we describe an algorithm for computing the dual of a projective plane curve. The algorithm requires no extension of the field of coefficients of the curve and runs in polynomial time.

β¦ Synopsis
In this paper we consider polyhedra whose geometric realization is the real projective plane. Each such polyhedron has a natural dual polyhedron. We give two covering constructions for projective polyhedra which are isomorphic to their duals and prove that these constructions yield all such polyhedra. 1993 Academic Press. Inc.

## Abstract There are exactly 60 inequivalent Hadamard matrices of order 24. In this note, we give a classification of the selfβdual π½~5~βcodes of length 48 constructed from the Hadamard matrices of order 24. Β© 2004 Wiley Periodicals, Inc.
In this note, the existence of self-dual codes and formally self-dual even codes is investigated. A construction for self-dual codes is presented, based on extending generator matrices. Using this method, a singly-even self-dual [70, 35, code is constructed from a self-dual code of length 68. This i
Starting from the metaphor of the person as a motivated storyteller, a theory of meaning construction and reconstruction is presented. Two motives are assumed to be particularly influential in the process of meaning construction: The striving for self-enhancement and the longing for contact and unio
The construction industry makes a vital contribution to the social and economic development of every country, but, at the same time, its building sector has major impacts on the environment. Construction is a major consumer of non-renewable resources (energy in particular), a substantial source of w
