The external environment of an organization is characterized by significant changes that occur in the social, economical, political and technological fields. The organization should know this setting and act effectively. A major challenge is how to define significant information in its diverse contexts. In a business process scenario, context could be defined as the minimum set of variables con...

Power-intensive processes can lower operating expenses when adjusting production planning according to time-dependent electricity pricing schemes. In this paper, we describe a deterministic MILP model that allows optimal production planning for continuous powerintensive processes. We emphasize the systematic modeling of operational transitions, that result from switching the operating modes of ...

It has been argued that the notion of substitution in the λ-calculus needs to be made explicit and many calculi have been developed in which the computational steps of the substitution operation involved in β-contractions have been atomised. In contrast to the great variety of developments for making explicit formalisations of the Beta rule, less work has been done for giving explicit definitio...

this study investigated the effectiveness of explicit pragmatic instruction on the acquisition of requests by college-level english as foreign language (efl) learners in taiwan. the goal was to determine first whether the use of explicit pragmatic instruction had a positive effect on efl learners’ pragmatic competence. second, the relative effectiveness of presenting pragmatics through two deli...

A key feature of human cooperation is that we can coordinate well without communication or negotiation. We achieve this by anticipating the intentions and actions of others, and adapting our own actions to them accordingly. In contrast, most multi-robot systems rely on extensive communication to exchange their intentions. This paper describes the joint approach of our two research groups to ena...

Face recognition systems have to deal with the problem that not all variations of all persons can be enrolled. Rather, the variations of most persons must be modeled. Explicit modeling of different poses is awkward and time consuming. Here, we present a subsystem that builds a model of pose variation by keeping a model database of persons in both poses, additionally to the gallery of clients kn...

This paper describes the features of a multistage ALM recourse model in light of the recent pension reform in the Netherlands. The main results are explicit modeling of indexation decisions and modeling of new regulatory rules.

We study a discrete analog of the Lagrange-d’Alembert principle of nonhonolomic mechanics and give conditions for it to define a map and to be reversible. In specific cases it can generate linearly implicit, semi-implicit, or implicit numerical integrators for nonholonomic systems which, in several examples, exhibit superior preservation of the dynamics. We also study discrete nonholonomic syst...
