The flood of alarms produced by Point-of-Care (PoC) medical devices in intensive care units (ICUs) and operating rooms (ORs) is a crucial issue of today's hospitals. Alarm fatigue and desensitization leads to the death of patients, noise worsens the patient's recovery process and causes burnout syndromes of caregivers, etc. Much research has been done in the last years to reduce false alarms and noise...
This paper presents monitoring as a service for networked medical cyber-physical systems in the operating room based on the recent IEEE 11073 standards for interoperable medical device communication. Runtime Verification techniques are used to allow for a formal specification and verification. Based on the specification so called monitors are automatically synthesized. At runtime, the monitors observe...
Market readiness of on-board automotive software-intensive systems is tightly linked to the availability of appropriate certification schemes aimed at keeping the car makers confident and the consumers safe - especially in the context of Autonomous Driving, which is the next frontier of the automotive industry. Advanced driver assistance systems (ADAS) are going to be pervasively used in modern automobiles...
In recent years, there has been a shift from closed systems, with clearly defined borders, whose behavior is completely determined a priori, towards open systems. An open system is an independently developed system, which is able to communicate and cooperate with other open systems in an ad-hoc manner, at runtime. Moreover, due to their openness, such systems may be used in various contexts. Whenever...
Systems of Systems (SoS) are defined - amongst other distinguishing features - as a collection of component systems that produce results not achievable by the individual systems alone. But SoS is more than just a higher level focus on factors that are primarily concerned with the mechanics of data handling. SoS deals with the process of work-in-progress and how the design drives the implementation...
The rapid development of extra-high voltage, smart power grid and energy internet leads to relative lagging of production management. This management strategy develops electric big data in depth and realizes an intelligent management platform with full life cycle management, standard defect closed-loop management, safety risk control, equipment state evaluation, etc. as its main carriers on the basis...
At three key sporting venues of the RIO 2016 Olympic Games, an innovative remote powering solution was used to deliver power from a central source to Remote Radio Units (RRUs) located on cell towers. The solution effectively powered the RRUs from a centralized source of DC power while providing battery backup protection. This paper describes the powering challenges faced by the Wireless Service Provider...
This paper proposes a reliable MAC protocol for a fully distributed Vehicular Ad-Hoc Network (VANET) using the slot states sharing scheme. Recently, technology for reliably transmitting safety messages in VANET has become an issue. With VANET (operating on the IEEE 802.11p standard), as the number of vehicles increases on the highway, the network traffic also increases. It causes more frequent packet...
Modern systems are becoming ever more complex and, thus, the possibility of failures in their operation is also growing. The complexity makes it practically impossible to make the hardware and software error-free without the special effort invested in the design process. Recently, a design methodology with the objective to avoid unacceptable risk of physical injury or of damage to the health of people,...
Dedicated Short Range Communications (DSRC), a promising vehicle-to-vehicle communication technology, has been under active research and large scale DSRC deployment is expected to start shortly. However, before all vehicles are deployed with DSRC, there will be a relatively long partial DSRC deployment period where DSRC-equipped vehicles and non-DSRC-equipped vehicles both exist on roads. More importantly,...
The characteristics of four mainstream protocols including Ethernet/IP, Profinet, EtherCAT and Ethernet Powerlink in industrial field network are analyzed respectively in the paper. According to the different requirements of the on-site production line level control system and the internal network of the automation equipment, it is significant to adopt the appropriate network protocol. In the on-site...
For a long time, the railway signal system adopts a dedicated closed network without problems such as external intrusion and network virus transmission. However, because of the high-speed and real-time data sharing requirements between the high-speed railway signal system and each subsystem, the network has seen an unprecedented openness. In recent years, with the new virus and attack in industrial...
With the gradual development and improvement of the comprehensive passenger terminal, there are many problems in the marking line of the integrated passenger terminal, which leads to the phenomenon that the passengers in the integrated passenger transport hub can not find the direction or mark confusion. At present, the lack of relevant standards for the marking line of integrated passenger terminal...
Brake system design is considered quite challenging due to conflicting safety constraints imposed on the system performance. As several components are integrated into the system, design focused exclusively on a single element does not guarantee efficient system performance. As a consequence, no general rules are provided in developing this type of system. This paper aims at proposing a quick and intuitive...
This paper describes how the use of an impact assessment reveals unknown information to project teams who conduct community engagement engineering projects in rural and distant villages. The paper depicts a “tried and tested” case study to describe how the impact assessment is done and the information revealed. The second phase of the Gwakwani project included the installation of off-grid solar home...
This paper presents the main results of a thesis work dedicated to the Specific Absorption Rate (SAR) risks in High-Frequency (HF), Very High-Frequency (VHF) and Ultra High-Frequency (UHF) frequency bands. The main goal of this thesis is to enhance SAR method validation of radio military exposure near high power antennas. It will permit to reduce cost and delay of SAR validation and quantify the actual...
Mixed-criticality systems (MCS) aim at boosting the integration density in safety-critical systems, resulting into efficient systems, while simultaneously providing increased performance. The DREAMS project provides a cross-domain architectural style for MCS based on networked, virtualized multi-cores controlled by hierarchical resource managers. However, the availability of a platform is only one...
This paper investigates the use of ultra-wideband (UWB) radio for communication in industrial wireless sensor networks (WSNs). OpenWSN is an open-source IPv6 mesh network protocol stack based on IEEE 802.15.4 time slotted channel hopping (TSCH). We adapted OpenWSN to operate an UWB physical layer based on the DecaWave DW1000 UWB transceiver. Experiments were conducted in an industrial steam heating...
This paper provides insight into the electrical safety considerations, related to the electrical systems and equipment for shipboard and marine terminal applications. These safety considerations are applicable to electricians and engineers who operate and maintain the electrical systems and equipment, which frequently occurs under adverse and dangerous conditions.
Certification compliance check for airborne software is very critical as it aids in the certification of the software. Since this compliance check is performed manually which is time-consuming and erroneous, an in-house developed Certification Compliance Tool (CCT) helps in checking the compliance as per RTCA DO-178B/C and generate artifacts depicting the magnitude of compliance. In order to generate...
