Tramway Networks as Route Graphs

The purpose of this paper is threefold: (1) to show a methodology for introducing formality step-by-step, starting from a “light-weight” ontology, (2) to apply it to the generic Route Graph model, instantiated here to Tramway Networks, and (3) to demonstrate that separation of concerns into layers of abstraction and application of generic formal notions such as graph abstraction lead to a usefu...

The Locomotive Routing Problem

Given a schedule of trains, the locomotive planning (or scheduling) problem (LPP) is to determine the minimum cost assignment of locomotive types to trains that satisfies a number of business and operational constraints. Once this is done, the railroad has to determine the sequence of trains to which each locomotive is assigned by unit number so that it can be fueled and serviced as necessary. ...

Grafting Locomotive Motions

The notion of transplanting limbs to enhance a motion capture database is appealing and has been recently introduced [Sha04], [Ike04]. A key difficulty in the process is identifying believable combinations. Not all transplantations are successful; we also need to identify appropriate frames in the different clips that are “cutpasted.” In this paper, we describe motion grafting, a method to synt...
