The purpose of this paper is twofold: to depict the patient's journey in operating block of the hospital and to provide a flexible model that matches the reality. In operating block of Jeanne de Flandres Hospital, a daily meeting is held in order to establish the operations that will occur the next day. Organizing a schedule in these circumstances leads to a loss of time and can often lead to conflictual...
Real-time Ethernet variants gain importance for communication infrastructure of various time-critical domains, such as in-car networks. Synchronous time-triggered traffic guarantees strict timing but requires a detailed schedule for all participants. Designing these schedules by hand is extensive work and with increasing network size almost impossible. In this paper, we contribute a mapping of the...
This paper presents a server-based framework for task overrun management in multi-core real-time systems. Unlike most existing scheduling methods which usually assume a single upper bound of the Worst-Case Execution Time (WCET) for each task, our approach targets scenarios with task overruns. The main idea of our framework is to employ Synchronized Deferrable Servers (SDS) to deal with globally scheduled...
Distributed systems rely in communication networks, typically a bus, in order to exchange messages and fulfill their goals. However, message transmission is subject to interferences that ultimately can lead to message corruption. In systems where a high-reliability is sought, error recovery mechanisms can be deployed in order to give the required reliability level, and this can be done in the spatial...
With multicore controllers becoming available for industrial automation applications, new tools and algorithms to compute efficient partitioning and scheduling solutions for control applications need to be developed. Optimizing the deployment and the schedule of a set of Function Block Diagrams on a parallel architecture are both NP hard. Additionally, control engineers need help to shift from the...
Development of the space industry has led to a diversity of specialized electronics-units implemented on space system. However, this provoked new problems such as increased system's complexity and the size. As a solution to the problem, the Integrated Modular Avionics (IMA) architecture and ARINC 653 standard have been suggested. This paper introduces a Linux-based memory efficient ARINC 653 partition...
Energy-aware scheduling is a challenging problem that has been studied for decades, investigating the trade-off between performance and energy consumption. In early CMOS circuits, Dynamic Voltage and Frequency Scaling (DVFS) techniques allowed drastically reducing the power consumption. Recent technological advancements have decreased the portion of dissipation which is affected by speed scaling,...
