Real-Time Systems Engineering and Applications
The aim of the project is to drive the standardisation within STEP and to validate the proposed standard through tool interface development and real data exchanges. Autonomous systems are promoted as a means of achieving a whole new range of services using the promises of AI and machine learning. New methodologies that deal with the rapid explosion of volume and significance of software in avionic systems so that added functionality can be created with lower costs is a hallmark of this project supported by the national program within innovation for airborne systems.
The research work will rest on the following three pillars: Data analysis and emulation Risk and vulnerability analysis using attack modelling Real-time detection of adverse events and anomalies. This project is founded on three pillars: the current state of the art in vehicular real-time communication and safety message dissemination, new advances in formal methods allowing previously intractable problems to be solved, and the mature body of work concerning fault-tolerant algorithms for distributed systems. This projects studies new development methodologies for the Integrated Modular Avionics concept to evaluate performance in early stages of design.
This project studies the integration of multicore processors in future avionic systems and in particular, the interplay between software resource requirements and hardware architecture and resource arbitration functions. Energy is a valuable resource for battery-driven devices which calls for its optimal utilisation.

Security has always been a stepchild to the developers of embedded systems. This project addresses reliable delivery in partition-tolerant and resource-constrained networks in three directions: designing a multicast algorithm for delay- and partition-tolerant networks, constructing abstract models of connectivity to systematically study trade-offs in such networks, and studying the use of resource-utility functions in routing algorithms for optimisation of resources.
This project is based on a long term industrial research problem for managing networks of cooperating UAVs connected via adhoc networks. This project is part of the current national aerospace research program NFFP4-S , with a focus on distributed modular avionics DMA architectures and their incremental verification. The goal of this project is to establish an engineering discipline for systematic development of component-based software for safety- critical embedded systems. The goal of this project is to develop platforms for real-time data services that involve techniques for managing unpredictability of the environment, handling imprecise or incomplete knowledge of the workload, reacting to overloads and unexpected failures i.
To address this problem, we aim at developing a management framework for real-time data services that provides guarantees on QoS and QoD in terms of several fundamental performance metrics for real-time applications. In order to provide guarantees, the system must be able to adapt to changes to the external environment, e. Initial research shows that feedback control scheduling is able to deal with dynamic systems that are both resource insufficient and that exhibit unpredictable workloads. Feedback control real-time scheduling defines error in terms for system behavior, i.
The error is continuously monitored, and the system is adjusted to maintain desired performance. Our research focuses on using feedback control scheduling as initial research has been promising in providing satisfactory QoS and QoD guarantees. This project aims to develop distributed algorithms for adaptive anomaly detection in resource-constrainted adhoc networks.

In particular, we study how detection of attacks and intrusions can be performed with little overhead in terms of computational resources, but utilising the knowledge about the normal behaviour of user applications in terms of network resource consumption, QoS parameters, amd their adaptation to dynamic changes in the network.
This work complements emerging trust models for adhoc and P2P networks. Its applications are envisaged where the adhoc solutions are used as an ingredient to bridge fixed infrastructure networks during failures or overloads, or simply to extend the reach of existing critical infrastructures.

The goal of the project is to provide a concept for optimizing dependability in distributed component based systems. It comprises an architecture, well defined technology integration rules, metrics for evaluation, as well as prototype implementations. The idea is to use replication for transparent fault tolerance and persistence, the focus being on the trade-off between consistency and availability.
For this a combination of synchronous and asynchronous replication is used. The studies are oriented towards measuring the trade-off and configuring it to allow an application-specific optimum of availability. The project also aims at the design and implementation of a fault-tolerant naming service adapted to the context of availability-consistency trading.
This project aims to combine architectures and algorithms for adaptive management of resource allocation in networked applications. In particular, we study how user requirements in terms of Quality of Service QoS can be met by system level resource allocation, when there are several types of uncertainties present. The project started by studying the load control problem for radio network controllers in 3rd Generation mobile telecom, and will continue by studying the general problem in multi-resource multi-criteria settings.
This project studies the application of fault-tolerant techniques in distributed systems.

We study formal models of fault-tolerance for achieving safety in safety-critical systems and availability in telecommunication applications. The work focuses on replication techniques in general, and group services in the case of software intensive monitoring systems, in particular. In this project we will study the impact of other typical demands on a system, e. To this end, trade-off studies are performed to study various approaches for implementing fault-tolerance in the middleware in presence of real-time and resource utilisation requirements.
This project is a multi-disciplinary effort to promote improvements in the system engineering process, in particular systems with heterogenenous components ranging from mechanical, hydarulic and electromechanical elements to software and electronics. The project is organised in a number of tracks including the following three at RTSLAB: Systems engineering support: Tool integration and standardisation Methodologies for industrial-strength formal methods Simulation databases The goal of this research is to bridge the gap between embedded systems, real-time systems and database systems, with a particular focus on the software development tools.
Significant amount of research has focused on how to incorporate database functionality into real-time systems without jeopardizing timeliness and how to incorporate real-time behavior into embedded systems. However, research for embedded databases used in embedded real-time systems, that explicitly address i the development and design process, and ii the limited amount of resources in embedded systems is sparse.
This type of research inherits the challenges from component-based software engineering, embedded systems and real-time systems. The example codes have been tested in QNX—a real-time operating system widely adopted in industry. Lastly, this book may benefit practicing embedded system engineers, but it is written especially for advanced undergraduates or master-level students who are pursuing a major in Computer Engineering, Software Engineering, or a related discipline.
As a textbook, a collection of problems are given at the end of each chapter. Instructors may extend some problems to design lab exercises. For example, Problem It is also a good idea to design a series of lab activities scattered through a semester so that each student or team of students may end up with a running system with real-time features.
In so doing, the instructor has to plan ahead to select an OS and the evaluation boards to be used.

Instead, instructors are free to choose any OSes for their classes. As an example, Dr. Another note is that sometimes the chosen evaluation board may not have all the functionality required for a system. In such a case, students may need extra materials on integrated circuit design. He received his Ph. Electronics and electrical engineering have practically limitless applications. From power engineering, telecommunications, and consumer electronics to circuit design, computer engineering, and embedded systems, these disciplines form the backbone of our increasingly tech-dependent world.

This way you can use a controller without FPU and thus benefit by saving energy with increased efficiency and reducing costs with implementing functions on small embedded platforms. This is the key competitive advantage for you, especially in systems with large numbers.
Real-time capability combined with low processor load — this makes the difference in embedded programming. Early identification of real-time conditions allows us to design systems for optimized use of existing computing power to keep hardware costs down to a minimum. Knowledge of hardware architectures and working with the most stringent quality control measures — these are our basic tenets for developing program codes with guaranteed execution time.
One of the fundamental challenges in development is compliance with maximum admissible processor loads. That is why we perform analyses, for our customers, to identify optimal runtimes.
