In this article we give a general method to compute sets of algebraic curves with prescribed incidence relations and tropicalizations. It generalizes the geometric constructions presented in Tabera, 2005 to the non linear case.

In 1964, Kautz and Singleton (IEEE Trans. Inform. Theory 10 (1964), 363–377) introduced the superimposed code concept. A binary superimposed code of strength s is identified by the incidence matrix of a family of finite sets in which no set is covered by the union of s others (J. Combin. Theory Ser. A 33 (1982), 158–166 and Israel J. Math. 51 (1985), 75–89). In the present paper, we consider a ...

This paper investigates the characteristics of Canadian manufacturing plants that are related to the use of advanced technologies. The data used are taken from the 1989 Survey of Manufacturing Technology and are linked to administrative data taken from the Census of Manufacturers. Technology use is defined first as incidence (whether a technology is used) and second as intensity (the number of ...

Under the right conditions it is possible for the ordered blocks of a path design PATH(v, k, ) to be considered as unordered blocks and thereby create a BIBD(v, k, ).We call this a tight embedding.We show here that, for any triple system TS(v, 3), there is always such an embedding and that the problem is equivalent to the existence of a (−1)-BRD(v, 3, 3), i.e., a c-Bhaskar Rao Design. That is, ...
