Internal working papers DIUF
Die Sammlung der Working Papers des DIUF ist eine Serie von Forschungsberichten, die das Departement für Informatik der Universität Freiburg (Schweiz) veröffentlicht hat. Diese Sammlung existiert seit 1958 und ist seit 2015 vollständig in digitaler Form verfügbar. Die Inhalte der Publikationen behandeln Themen der Forschung im Bereich Informatik, Operations Research und der Statistiken.
Die Sammlung wurde publiziert in den Jahren 1958 bis 1995 unter dem Namen Institut für Automation (IAUF) und in den Jahren 1986 bis 1995 unter dem Namen Laboratorium für Informatik (LIUF) veröffentlicht, später von 1995 bis 2000 unter dem Namen Institut für Informatik (IIUF).

N-light-N : Read The Friendly Manual

Seuret, Mathias ; Alberti, Michele ; Liwicki, Marcus

(Internal working papers DIUF ; 16-02)

This documentation wants to be a "user manual" for the N-light-N framework. The goal is not only to introduce the framework but also to provide enough information such that one can start modifying and upgrading it after reading this document. This document is divided into five chapters. The main purpose of Chapter 1 is to introduce into our notation and formulation. It refers to further...

Towards human-centered cyber-physical systems : a modeling approach

Hadorn, Benjamin ; Courant, Michèle ; Hirsbrunner, Béat

(Internal working papers DIUF ; 16-01)

In this paper we present a new CPS model that considers humans as holistic beings, where mind and body operate as a whole and characteristics like creativity and empathy emerge. These characteristics influence the way humans interact and collaborate with technical systems. Our vision is to integrate humans as holistic beings within CPS in order to move towards a human-machine symbiosis. This...

Gesturing on the steering wheel, a comparison with speech and touch interaction modalities

Angelini, Leonardo ; Baumgartner, Jürgen ; Carrino, Francisco ; Carrino, Stefano ; Caon, Maurizio ; Abou Khaled, Omar ; Sauer, Jürgen ; Lalanne, Denis ; Mugellini, Elena ; Sonderegger, Andreas

(Internal working papers DIUF ; 15-03)

This paper compares an emergent interaction modality for the In-Vehicle Infotainment System (IVIS), i.e., gesturing on the steering wheel, with two more popular modalities in modern cars: touch and speech. We conducted a betweensubjects experiment with 20 participants for each modality to assess the interaction performance with the IVIS and the impact on the driving performance. Moreover, we...

The no-wait job shop with regular objective : a method based on optimal job insertion

Gröflin, Heinz ; Bürgy, Reinhard

(Internal working papers DIUF ; 15-02)

The no-wait job shop problem (NWJS-R) considered here is a version of the job shop scheduling problem where, for any two operations of a job, a fixed time lag between their starting times is prescribed. Also, sequence-dependent set-up times between consecutive operations on a machine can be present. The problem consists in finding a schedule that minimizes a general regular objective function. We...

Complementing Büchi automata with a subset-tuple construction

Allred, Joel ; Ultes-Nitsche, Ulrich

(Internal working papers DIUF ; 15-01)

Complementation of Büchi automata is well known for being difficult. In the worst case, a state-space growth of (0:76n)n is unavoidable. Recent studies suggest that “simpler” algorithms perform better than more involved ones on practical cases. In this paper, we present a simple “direct” algorithm for complementing Büchi automata. It involves a structured subset construction (using...
