In Asia, many documents processed in offices are table-form documents. Hence the automatic processing of table-form documents is an important issue of the office automation research. In this paper, we propose an efficient representation method for table-form documents. The representation method is based on three types of line segments. The line segments are normalized and sorted, hence the repr...

This paper reports on a design process of e-learning courses for competence development of experienced employees in the manufacturing industry. Through a crossorganizational collaborative action design research project the aim was to design e-learning courses at university level to support work-integrated learning. Two designand learning cycles were evaluated over two years. The first cycle ide...

This paper addresses the problem of extracting three-dimensional geometric information from a single, uncalibrated image of a scene. This work, building upon [7], is divided into two parts. The first part describes, in simple steps, the basic algorithms to obtain partial or complete geometric reconstruction from single perspective images of a scene. The second part presents a panorama of applic...

ing captures information about the cable itself: its document number, source, date, etc. Indexing captures information about the entities described in the cable: their names, dates of birth, locations, etc. The result of the abstracting and indexing process is a set of index records about the entities that were described in a cable. When a cable has been abstracted and indexed, its index record...

We consider long-time simulations of two-dimensional turbulence body forced by sin 4yx̂ on the torus (x, y) ∈ [0, 2π]2 with the purpose of extracting simple invariant sets or ‘exact recurrent flows’ embedded in this turbulence. Each recurrent flow represents a sustained closed cycle of dynamical processes which underpins the turbulence. These are used to reconstruct the turbulence statistics usi...

Most current crowd simulators animate homogeneous crowds, but include underlying parameters that can be tuned to create variations within the crowd. These parameters, however, are specific to the crowd models and may be difficult for an animator or naïve user to use. We propose mapping these parameters to personality traits. In this paper, we extend the HiDAC (HighDensity Autonomous Crowds) sys...

Although extensive literature on BPR is available, there is still a lack of concrete guidance on actually changing processes for the better. It is our goal to provide a redesign approach which describes and supports the steps to derive from an existing process a better performing redesign. In this paper we present an evolutionary approach towards business process redesign and explain its first ...

Although extensive literature on BPR is available, there is still a lack of concrete guidance on actually changing processes for the better. In this paper we propose and detail out an evolutionary approach towards business process redesign. We describe the steps to derive a better performing redesign using the existing process model as input. The redesign steps are: 1) computing process measure...

When using process models for automation, correctness of the models is a key requirement. While many approaches concentrate on control flow verification only, correct data flow modeling is of similar importance. This paper introduces an approach for detecting and repairing modeling errors that only occur in the interplay between control flow and data flow. The approach is based on place/transit...

The Workflow Reengineering Methodology (WRM) is a proposed methodology that uses workflow management automation to enable Business Process Reengineering (BPR). Unlike published BPR methodologies that use historical and estimated process data gathered from workflow participants, WRM uses the more accurate, real-time process measurements, gathered by the workflow tool, to improve the efficiency, ...
