Based on a grid concept of an interactive hybrid online laboratory we will describe different fields of applications in different learning scenarios. This infrastructure guaranties a reliable, flexible as well as robust usage of this online lab. By using GOLDi, students are able to design control algorithms with different specification techniques to control electro-mechanical hardware models in the online lab. Additionally, the reconfigurable rapid prototyping platform of the GOLDi system can be used to test all the taught topics of a given lectures in the field of digital system design. Finally, a special demonstration platform (a ball in a labyrinth on a balance plate) can be used to give the students a better feeling about the possibilities and limitations of remote control and observation via Internet and to evaluate these technologies critically.

Mobile ad-hoc networks (MANETs) enable ubiquitous computing with wide availability of smart mobile devices and applications. However, robust and lightweight protocols are yet to be implemented for multihop communication. The latest ieee 802.11 standard released in 2012 captures the concept of multihop MANETs under Wireless Mesh Networks and proposes Hybrid Wireless Mesh Protocol (HWMP) as the default multihop path selection protocol. Previous studies on the performance of HWMP have not addressed operating scenarios of mass mobility (to model human user mobility), non-availability of root nodes (to model absence of infrastructure support) and a wide span of node densities (to model different application scenarios). This paper analyses the scalability of HWMP in a MANET of ieee 802.11 standard wireless mesh stations that move at human walking speeds. The end-to-end delay, data packet delivery ratio and path selection control overhead are evaluated in the presence of random waypoint and mass mobility models for increasing node densities. The simulation results show that there are no significant variations in any of the above important performance metrics among static, random waypoint mobility and mass mobility models. Furthermore, HWMP shows almost a linear path selection control overhead profile for increasing node densities while the packet delivery ratio and the end-to-end delay reaches a steady level as node density increases up to about 250 nodes.

There is a class of control algorithms, which are based on models of the controlled processes. The common feature of these algorithms is the fact that at the design stage the algorithm can be modified to take into account multiple sensors available in the controlled plant. Each additional independent measurement increases the accuracy of the simulation carried on by the model embedded in the algorithm. In this work the authors propose to improve this established static approach and implement the controlsystem which dynamically derives the control law during its operation, depending on the availability of individual sensors. Availability may be reduced in the event of sensor failure, or increased after new sensors are connected. It is proposed to employ the agent-based programming paradigm as it has the dynamic reconfiguration capabilities which are crucial for the proposed technique. The presented idea is still a work on progress, so no experimental results are available, but this paper focuses on the details of the proposed technique in order to collect the opinions and conclusions of the research and engineering community.

In systems and service engineering testing is an important part to get confidence in quality and trust in security issues. Standardized testing techniques support the unique definition of abstract test models, configurations and behavior scenarios that can be executed automatically. This contribution presents the state of the art and future directions of two international standards for testing: the Testing and Test control Notation (TTCN-3) from the European Telecommunication Standardization Institute (ETSI), and the UML testing profile (UTP) from the Open Management Group (OMG). Special emphasize is given to the translation from UTP to TTCN-3 test models, automated test execution using standard-compliant tool support and related examples from European projects.

Relevant modules of a metabolic network can reveal the underlying structure of the metabolic system and hence provide the insight into its function. Modularity is a useful standard for decomposing a complex network. However, it has been shown that simply optimizing modularity failed to find the most natural community structure by overpartition or under partition the network. Here, a novel network decomposition algorithm, called MNetDec, is proposed by integrating the dendrogram and modularity features of a metabolic network. By dealing with MNetDec, the small modules with questionable biological function are eliminated. Moreover, the size of the smallest module and final number of the modules in the decomposition result can be flexibly set by the users based on their own specific needs. The application of this algorithm on brain specific human metabolic network shows that MNetDec can generate biological reasonable modules with high modularity.

Tracking and rejecting periodic signals are common tasks in many control applications. A well-known use of Repetitive control (RC) is to both track a periodic reference signal and reject periodic disturbance. This paper reviews various designs of RC that are classified into basic RC design and robust RC design. The recent applications of RC are also presented in this paper.

Mobile devices are getting more capable every year, allowing a variety of new applications, such like supporting pedestrian navigation in GPS-denied environments. In this paper we deal with the problem of combining in real-time dead reckoning data from the inertial sensors of a smartphone, and the WiFi signal fingerprints, which enable to detect the already visited places and therefore to correct the user's trajectory. While both these techniques have been used before for indoor navigation with smartphones, the key contribution is the new method for including the localization constraints stemming from the highly uncertain WiFi fingerprints into a graphical problem representation (factor graph), which is then optimized in real-time on the smartphone. This method results in an Android-based personal navigation system that works robustly with only few locations of the WiFi access points known in advance, avoiding the need to survey WiFi signal in the whole area. The presented approach has been evaluated in public buildings, achieving localization accuracy which is sufficient for both pedestrian navigation and location-aware applications on a smartphone.
