In this paper we study some structure properties of primitive weird numbers in terms of their factorization. We give sufficient conditions to ensure that a positive integer is weird. Two algorithms for generating weird numbers having a given number o

We give an algorithm to enumerate all primitive abundant numbers (briefly, PANs) with a fixed $\Omega$ (the number of prime factors counted with their multiplicity), and explicitly find all PANs up to $\Omega=6$, count all PANs and square-free PANs u

The detection of influential observations for the standard least squares regression model is a question that has been extensively studied. LAD regression diagnostics offers alternative approaches whose main feature is the robustness. In this paper a

A new family of sequences is proposed. An example of sequence of this family is more accurately studied. This sequence is composed by the integers $n$ for which the sum of binary digits is equal to the sum of binary digits of $n^2$. Some structure an

Severe visual impairments make it difficult for users to work on a computer. For this reason, there is great demand for new technical aids on the computer to compensate for these limitations. Current magnification software makes it possible to adjust

Autor:
Melfi, Giuseppe, Müller, Karin
Der Bericht enthält Kriterien für die Erstellung taktiler Indoor Karten mittels des im AccessibleMaps Projekt entwickelten Accessible Tactile Indoor Map Symbolsets (ATIM). Das Symbolset basiert auf einem Teil der ATMAPS Symbole, die für Schwellkop
