Approximating distribution functions by iterated function systems [PDF]

open access: yes, 2005
An iterated function system (IFS) on the space of distribution functions is built with the aim of proposing a new class of distribution function estimators. One IFS estimator and its asymptotic properties are studied in detail.

Smart selective navigator (SSN): enhancing urban winter road maintenance through optimized arc routing with hard turn restrictions

open access: yesInternational Transactions in Operational Research, Volume 33, Issue 5, Page 3580-3597, September 2026.
Abstract This paper introduces a novel heuristic method, the smart selective navigator (SSN), for addressing arc routing problems (ARPs) with a focus on integrating hard turn restrictions in urban winter operations. Addressing a significant gap in existing ARP methodologies, SSN seamlessly incorporates common side constraints, such as vehicle ...

Temperature Dependent Complex Refractive Index (CRI) of Hexagonal Ice in the Range 150–270 K: Infrared and Far‐Infrared Transmission Measurements at the AILES Beamline

open access: yesGeophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract The complex refractive index (CRI) of ice is one of the main parameters driving the optical properties of ice clouds and frozen surfaces, hence their climate impact. While already characterized at short wavelengths, ice CRI has never been measured across the infrared range at temperatures relevant to Earth.

Iterated function systems and fractals

open access: yes
openIn questa tesi vengono gettate le basi per lo studio degli iterated function systems (IFS). Viene studiata la distanza di Hausdorff e alcune proprietà topologiche che ne derivano, vengono poi definiti e studiati gli IFS ed i loro attrattori in varie

On Contraction Principles in Product Spaces and Applications in Iterated Function Systems

open access: yesAxioms
This paper develops an extension of the research work by Proinov to the product spaces X|I| (I is representing an indexing set). This paper also introduces a novel class of (L;Y)-contractions defined on a supremum metric (X|I|,d′).
