Applications typically rely on the operating system to enforce access control policies such as MAC, DAC, or other policies. However, in the face of a compromised operating system, such protection mechanisms may be ineffective. Since security-sensitive applications are most motivated to maintain access control to their secret or sensitive information, and have no control over the operating syste...

The robot development environment (RDE) ArmarX aims at providing an infrastructure for developing a customized robot framework that allows realizing distributed robot software components. This includes communication properties, start-up and error handling, mechanisms for state implementations, interface definitions and concepts for the structured development of robot programs. In addition to th...

This paper deals with the design of a fuzzy controller (FC) based on pole assignment method for the control of a liquid level system. The problem is to control level set point changes by adjusting the flowrate of liquid entering the tank through a feed pump [2], [5]. The behaviour of the closed loop fuzzy system controlled by the fuzzy controller is identical to the linear system whose state tr...

Fine-grained elasticity control of cloud services has to deal with multiple elasticity perspectives (quality, cost, and resources). We propose a cloud services elasticity control mechanism that considers the service structure for controlling the cloud service elasticity at multiple levels, by firstly defining an abstract composition model for cloud services and enabling multi-level elasticity c...

Control applications are more and more an integral part of modern embedded systems. As a result, considering the quality of control applications as a design objective while respecting design constraints like stability becomes mandatory. The work at hand proposes a fullyautomatic toolflow at the Electronic System Level (ESL) that enables the optimization of a system implementation with quality o...

This text gives experimental results, comments and interpretations of a set of compliant motion tasks that form the basis for force-guided identification of the geometry of the most common contact situations. The experiments show the influence of (i) nonideal effects, (ii) nonlinearities, and (iii) different motion trajectories.

This paper presents a programmable logic-based agent control system that interleaves planning, plan execution and perception. In this system, a program is a collection of logical formulae describing the agent’s relationship to its environment. Two such programs for a mobile robot are described — one for navigation and one for map building — that share much of their code. The map building progra...

Level of detail (LOD) and character animation are both well-explored fields in computer graphics, but little has been done to combine them. Level of detail refers to the generation and use of low-detail models in place of high-detail ones where this will not be visible (for example, for far-away objects). A method that combines LOD with character animation will make it practical to render crowd...

Will reading habit influence your life? Many say yes. Reading meta level control for deductive database systems is a good habit; you can develop this habit to be such interesting way. Yeah, reading habit will not only make you have any favourite activity. It will be one of guidance of your life. When reading has become a habit, you will not make it as disturbing activities or as boring activity...

This paper considers a bi-level discrete-time control framework with real-time constraints, consisting of several local controllers and a central controller. The objective is to bridge the gap between the online convex optimization and real-time control literature by proposing an online control algorithm with small dynamic regret, which is a natural performance criterion in nonstationary enviro...
