SONET/SDH Ring Assignment with Capacity Constraints

- O. Goldschmidt, A. Laugier, E. Olinick
- Mathematics, Computer Science
- Discret. Appl. Math.
- 15 June 2003

We consider the problem of interconnecting a set of customer sites using bidirectional SONET rings of equal capacity. Each site is assigned to exactly one ring and a special ring, called the federal… Expand

Algorithms to evaluate the reliability of a network

- J. Galtier, A. Laugier, P. Pons
- Mathematics
- DRCN ). Proceedings.5th International Workshop on…
- 27 December 2005

We consider problems of network reliability: the two-terminal network reliability consists, given an undirected graph G/spl equiv/(V, E), and a series of independent edge failure events, in computing… Expand

Brane to bulk supersymmetry breaking and radion force at micron distances

- I. Antoniadis, K. Benakli, A. Laugier, T. Maillard
- Physics
- 26 November 2002

Abstract We study mediation of supersymmetry breaking in the bulk, in models with primordial supersymmetry breaking on D-branes at the string scale, in the TeV region. We compute the gravitino and… Expand

D-brane models with non-linear supersymmetry

- I. Antoniadis, K. Benakli, A. Laugier
- Physics
- 22 November 2001

Abstract We study a class of type I string models with supersymmetry broken on the world-volume of some D-branes and vanishing tree-level potential. Despite the non-supersymmetric spectrum,… Expand

Stability in multi-skill workforce scheduling

- M. Firat, C. Hurkens, A. Laugier
- Computer Science
- 2010

This paper analyzes stability in multi-skill workforce schedules. In our stability analysis, we extend the notion of blocking pairs as stated in the Marriage model of Gale-Shapley. It is shown that… Expand

Thermodynamics and phase diagram calculations in II-VI and IV-VI ternary systems using an associated solution model

- A. Laugier
- Materials Science
- 1 September 1973

2014 The thermodynamic properties and the T-x phase diagrams for liquid-solid equilibrium in II-VI and IV-VI ternary systems are described by a regular associated liquid solution model derived from… Expand

Stable multi-skill workforce assignments

- M. Firat, C. A. J. Hurkens, A. Laugier
- Computer Science, Mathematics
- Ann. Oper. Res.
- 1 February 2014

This paper analyzes stability in multi-skill workforce assignments of technicians and jobs. In our stability analysis, we extend the notion of blocking pairs as stated in the Marriage model of… Expand

A Branch-and-Price algorithm for stable workforce assignments with hierarchical skills

- M. Firat, Dirk Briskorn, A. Laugier
- Computer Science, Mathematics
- Eur. J. Oper. Res.
- 1 June 2016

This paper deals with assigning hierarchically skilled technicians to jobs by considering preferences. We investigate stability definitions in multi-skill workforce assignments stemming from the… Expand

Viscosity of the glass-forming GeSe liquid solutions

- A. Laugier, G. Chaussemy, J. Fornazero
- Materials Science
- 1 April 1977

Abstract In the range 0 1 3 , a large increase of x in kinematic viscosity of GexSe1−x liquids is observed below 800°C. It is attributed to the branching effect of Ge. For compositions less than the… Expand

On the minimum number of edges of two-connected graphs with given diameter

- A. Jarry, A. Laugier
- Mathematics, Computer Science
- Discret. Math.
- 1 February 2012

We answer the following question: what is the minimum number of edges of a 2-connected graph with a given diameter? This problem stems from survivable telecommunication network design with… Expand
