This article proposes and studies a link between statistics and the theory of Dirichlet forms used to compute errors. The error calculus based on Dirichlet forms is an extension of classical Gauss’ approach to error propagation. The aim of this paper is to derive error structures from measurements. The links with Fisher’s information lay the foundations of a strong connection with experiment. H...

The increasing adoption of process-aware information systems (PAISs) has resulted in large process model collections involving different process participants. We present the Clavii BPM platform, which enables end users to participate not only in process model execution, but model creation as well. Clavii offers a modern user interface with a strong focus on ease of use, unifying different aspec...

In today’s distributed and dynamic business environment companies and their business processes are frequently subject to changes, requiring the ability to continuously evolve business processes in a flexible and dynamic way according to changing external conditions. Taking flexibility as the ability to react to changes by adaptation, it appears appropriate to take the environment, where a chang...

This paper continues the project, initiated in [ACK], of describing general conditions under which relative splittings are derivable in the local structure of the enumeration degrees, for which the Ershov hierarchy provides an informative setting. The main results below include a proof that any high total e-degree below 0′ e is splittable over any low e-degree below it, a non-cupping result in ...

In process-centric enterprises, business processes (BPs) are at the center of value-creating activities. Governing enterprise BPs requires the ability to control and guide BP behavior. Ensuring compliance of processes to legal regulations and strategy directives becomes a critical requirement. Implementing business process compliance makes means for modeling and enforcing compliance measures ne...

A novel graph-based utterance generation method for open-domain dialogue systems is proposed in this paper. After an association graph of words and utterance patterns from a dialogue corpus is constructed, a label propagation algorithm is used for generating system utterances from the words and utterance patterns in the association graph that are found to strongly correlate with the words and u...

A company’s competitiveness relies heavily on its business processes and accurate knowledge to execute its business processes with agility and efficiency. Business Process Management (BPM) initially promised to provide the business world with suitable tools and techniques for successful BPM without help from the IT world. However, the current practice of BPM has several fundamental problems, in...

In this paper we will investigate the capacity and mutual information of a broadband fading channel consisting of a finite number of time-varying paths. We will show that the capacity of the channel in the wideband limit is the same as that of a wideband Gaussian channel with the same average received power. However, the input signals needed to achieve the capacity must be “peaky” in time or fr...
