The automated enactment of processes through the use of workflow management systems enables the transfer of control flow from application systems to workflow management systems. By now a large number of different systems, that follow different interpretations of the workflow paradigm, are available. This leads to the problem of selecting the appropriate workflow management system for a given si...

Many modern manufacturing systems are highly automated and are now requiring decentralised ‘smart’ architectures to control hardware and manage the flow of materials / knowledge, in order to provide responsiveness. This responsiveness is needed to satisfy an ever increasing consumer need for goods that satisfy their unique requirements and are delivered to market both quickly and economically. ...

Efficient and secure management of access to resources is a crucial challenge in today’s corporate IT environments. During the last years, introducing company-wide Identity and Access Management (IAM) infrastructures building on the Role-based Access Control (RBAC) paradigm has become the de facto standard for granting and revoking access to resources. Due to its static nature, the management o...

-In the realms of communication technology, new paradigms are emerged in existing communication networks. Therefore, over the past decade, the major innovation in the area of networking has arisen the need of a new paradigm of control systems, namely Networked Control Systems. Such systems differ from the classical control systems in that their control loops are closed around communication netw...

Traditional access control models and mechanisms struggle to contain the threats posed by malware and software vulnerabilities as these cannot differentiate between processes acting on behalf of users and those posing threats to users’ security as every process executes with the full set of the user's privileges. Existing application confinement schemes attempt to address this by limiting the a...

We investigate the cognitive control in polyrhythmic hand movements as a model paradigm for bimanual coordination. Using a symbolic coding of the recorded time series, we demonstrate the existence of qualitative transitions induced by experimental manipulation of the tempo. A nonlinear model with delayed feedback control is proposed, which accounts for these dynamical transitions in terms of bi...

Autonomy is a necessary part of the design of agents flexible enough to function effectively and efficiently in a sophisticated world. Much work, however, has taken a very restricted view of what is entailed by autonomous interaction; in particular, the effects of an interaction have, to some extent, been guaranteed. In this paper, we argue that no facet of interaction can ever be guaranteed, a...

Middleware influenced the research community in developing a number of systems for controlling access to distributed resources. Nowadays a new paradigm for lightweight integration of business resources has started to hold Business Processes for Web Services. Authorization and access control policies for Web Services protocols and distributed systems are well-studied and standardized, but there ...

The complete control system design effort involves many stages during which partial design tasks are completed. Each of these tasks requires different modeling paradigms and different tools. Furthermore, the designed embedded control system entails a wide variety of implementation technologies that all require different specification formalisms. To handle such a multitude of modeling paradigms ...
