In this article, we present a hierarchical multirate control architecture for nonlinear autonomous systems operating in partially observable environments. Control objectives are expressed using syntactically co-safe linear temporal logic (LTL) specifications and the system is subject to state input constraints. At highest level of abstraction, model system–environment interaction discrete mixed...

In this paper we discuss collaborative version control issues in a hypertext architecture which has been deened using an agent-level design metaphor. Within this perspective all the basic activities which rule the functioning of the hypertext are formulated in terms of collaborative, parallel mechanisms, which organize global tasks disseminating knowledge and duties over a population of computa...

Due to the phasing out of nuclear energy in Germany there are a growing number of nuclear facilities that have to be decommissioned within the next years. In this context a multitude of surfaces in nuclear facilities have to be decontaminated. Manipulator-deployed systems offer a suitable solution and are properly designed for this kind of task. Beyond that they can be used for the processing o...

This memo outlines high-level requirements for the integration of flexible Mandatory Access Control (MAC) functionality into the Network File System (NFS) version 4.2 (NFSv4.2). It describes the level of protections that should be provided over protocol components and the basic structure of the proposed system. The intent here is not to present the protocol changes but to describe the environme...

Reducing energy consumption of climate control systems is important in order to reduce human environmental footprint. We consider a method for an automated agent to provide advice to drivers which will motivate them to reduce the energy consumption of their climate control unit. Our approach takes into account both the energy consumption of the climate control system and the expected comfort le...

This research is concerned with studying the dynamic performance of reconfigtirable Manufacturing Planning and Control (MPC) systems. Such goal requires two main tasks. The first task is to develop a dynamic MPC system model that has the ability to reconfigure to different MPC poli~,;es. The second task is to design a supervisory control unit that has as input the high level strategic market de...

the objective of this article is to derive the necessary optimality conditions, known as pontryagin's minimum principle, for fuzzy optimal control problems based on the concepts of differentiability and integrability of a fuzzy mapping that may be parameterized by the left and right-hand functions of its $alpha$-level sets.

Embedded systems consisting of collaborating agents capable of interacting with their environment are becoming ubiquitous. It is crucial for these systems to be able to adapt to the dynamic and uncertain characteristics of an open environment. The question of when this adaptation process should be done and how much effort should be invested in the adaptation becomes especially challenging in th...
