In this paper, we introduce a runtime monitoring method for Actor-based programs and present a Scala module that realizes the proposed method. The primary characteristic of our method is that it supports asynchronous message-passing based on the Actor model. Besides, the module does not require specialized languages for describing application properties to be monitored. Once a developer incorporates...
Source location privacy (SLP) is an important property for the class of asset monitoring problems in wireless sensor networks (WSNs). SLP aims to prevent an attacker from finding a valuable asset when a WSN node is broadcasting information due to the detection of the asset. Most SLP techniques focus at the routing level, with typically high message overhead. The objective of this paper is to investigate...
Na nossa sociedade, existem várias formas de crimes que ocorrem com bastante freqüência. No combate ao crime, vários sistemas safe-return estão a ser desenvolvidos para pessoas vulneráveis. Contudo estes sistemas focam-se principalmente na resposta a situações em que o perigo já aconteceu, não é feita nenhuma previsão de um possível crime. Estas previsões de situações de perigo podem ser feitas com...
This paper addresses requirements from future automotive electronics system concept/design to computing technology or platform filling processing characteristics which will be used in applications of automated driving generation. We cannot completely predict future trends of functionality or application, so it is important to have flexible and scalable computing platform for that generation. The platform...
The main purpose to push the development towards autonomous maritime operations in shipping and offshore installations, is to increase the performance of maritime activities; by social benefits for staff or other related personal groups; by economic benefits when the ability to increase the cargo or effectuate better space allocation; by environmental benefits that's allow the ship operations to be...
The trade-off between distortion-handling and keeping a wide field of view (FOV) is a problem affecting pedestrian detection systems of automobile rearview monitors that use on-vehicle fisheye cameras. We propose an image warping approach, called horizontal panorama mosaicing (HPM), as a solution to the problem. HPM is designed to (1) recover collinearity in the vertical direction and (2) create a...
Increasing penetration of renewable energy resources (RES) and electrification of services by implementing distributed energy resources (DER) has caused a paradigm shift in the operation of the power system. The controllability of the power system is predicted to be shifted from the generation side to the consumption side. This transition entails that the future power system evolves into a complex...
In the last decades, Remotely Piloted Aircraft Systems (RPAS) have been developed for many civil applications, such as surveillance and terrain monitoring, Search and Rescue (S&R), topography, photogrammetry and law enforcement missions, and widely media and entertainment applications. Moreover, the use of the unmanned configuration is becoming very promising for smart farming or precision agriculture...
This paper introduces the safe situation of coal production and the current situation of data driven applications in coal mine safety early warning. Through the analysis of coal mine monitoring data and coal mine safety accidents, this paper presents a fault diagnosis method based on principal component method and BP neural network. The principal component method is used to extract the information...
An integrated system has been developed for managing slopes along the national freeways in Taiwan. The management system utilizes GIS, ICT, and mobile technologies to assist the freeway authorities in freeway maintenance, monitoring, and drivers' safety. The mobility of system enables immediate access to necessary environmental and monitoring information, and provides an interface of simple, spatial,...
The reliability and safety of industrial machines depends on their timely maintenance. The integration of Cyber Physical Systems within the maintenance process enables both continuous machine monitoring and the application of advanced techniques for predictive and proactive machine maintenance. The building blocks for this revolution — embedded sensors, efficient preprocessing capabilities, ubiquitous...
In this study, an IoT-based bridge safety monitoring system is developed using the ZigBee technology. This system is composed of: (1) monitoring devices installed in the bridge environment; (2) communication devices connecting the bridge monitoring devices and the cloud-based server; (3) a dynamic database that stores bridge condition data; and (4) a cloud-based server that calculates and analyzes...
The paper presents a methodology for determination and evaluation of the influence of advertising equipment on the road traffic safety. Research is based on analysis of advertisement along the primary road network in the Czech Republic and defines individual measures to resolve identified issues. Proposed solutions are based on combination and synthesis of various methodological approaches, including...
Soft targets and crowded places are closely related with a risk of attacks or negative incidents, which can cause the loss of human live or interests protected by law. Soft targets are specified as the objects (building or event) with a large number of visitors in a closed place at the same time and simultaneously without integrated the special security and safety measures into the management processes...
Accurate and safe train position determination is of great importance for railway systems. Additionally, it has become one of the biggest challenges for the Safety-of-Life (SoL) services in railway transport systems using GNSS techniques. The critical performance requirements of these services promote the users to develop safe Train Positioning Systems (TPSs), in which integrity has to be highly concerned...
Robotic technologies are continuously transforming the domestic and the industrial environments. Recently the Robotic Operating System (ROS), has been widely adopted both by industry and academia, becoming one of the most popular middleware frameworks for developing robot applications. Guaranteeing the correct behaviour of robotic systems is, however, challenging due to their potential for parameterization...
Exposure to safety-critical thinking grows in importance as society increasingly depends upon software to control physical devices with potential safety impacts. In this unique graduate capstone experience we engaged graduate Software Engineering students in the specification, design, implementation, validation, and assurance of potentially safety-critical software-intensive products involving physical...
With the development of wind power technology, the installation of the wind turbines increase greatly in amount, the workload of the maintenance is also growing rapidly, the wind tower free climbing device play an important role in the daily inspection and maintenance work. To overcome the shortcomings existed in the style that manage and maintain the tower free climbing device, this paper proposes...
To solve the problem of high-energy-consumption of Wireless Sensor Network (WSN) nodes and short WSN lifetime, considering the practical underground environment of coal mine, this paper proposes a novel event-driven WSN in the coal mine system. The paper also discusses different working patterns of the proposed event-driven WSN, and switching methods between them. According to the safety regulation...
High-speed railway is being developed rapidly; its safety, including infrastructure and train operation, is vital. This paper presents a railway-subgrade vibration monitoring scheme based on phase-sensitive OTDR for railway safety. The subgrade vibration is detected and rebuilt. Multi-dimension comprehensive analysis (MDCA) is proposed to identify the running train signals and illegal constructions...
