Kramer avant Kramer : les récits des années 1980

Structural Stefan Kramer

In many real-world domains the task of machine learning algorithms is to learn a theory for predicting numerical values. In particular several standard test domains used in Inductive Logic Programming (ILP) are concerned with predicting numerical values from examples and relational and mostly non-determinate background knowledge. However, so far no ILP algorithm except one can predict numbers a...

On Kramer-Mesner matrix partitioning conjecture

In 1977, Ganter and Teirlinck proved that any 2t× 2t matrix with 2t nonzero elements can be partitioned into four submatrices of order t of which at most two contain nonzero elements. In 1978, Kramer and Mesner conjectured that any mt× nt matrix with kt nonzero elements can be partitioned into mn submatrices of order t of which at most k contain nonzero elements. In 1995, Brualdi et al. showed ...

A warning from the cradle?

LE TAUX DE MORTALITÉ INFANTILE est généralement reconnu comme un indicateur valable de la santé de la population d’un pays. Comme le signalent les Drs K.S. Joseph et Michael S. Kramer (page 535), après avoir diminué constamment pendant des années, le taux au Canada a augmenté légèrement de 1992 à 1993 et il est resté stable en 1994. Ils font état également d’une hausse marquée du taux de naissa...

Kramer , Not Your Mouthpiece : Abortion , Ideology , and

A new species of Tozzita Kramer (Hemiptera: Cicadellidae: Neocoelidiinae) and first record of Tozzita ips Kramer from Brazil.

A new species of Tozzita Kramer, 1964, Tozzita bifida sp. nov., is described and illustrated. The new species can be distinguished from the other species of the genus by the following characteristics: (1) forewing with commissural brown band; (2) pygofer with dentiform process on ventral margin and apex not spatulate; (3) subgenital plates with macroseta at apex; (4) style with preapical lobe d...
