Security Decisions for Cyber-Physical Systems based on Solving Critical Node Problems with Vulnerable Nodes

Cyber-physical production systems consist of highly specialized software and hardware components. Most components and communication protocols are not built according to the Secure by Design principle. Therefore, their resilience to cyberattacks is limited. This limitation can be overcome with common operational pictures generated by security monitoring

An Extended Virtual Force-Based Approach to Distributed Self-Deployment in Mobile Sensor Networks

International Journal of Distributed Sensor Networks, 2012
Virtual physics based approach is one of the major solutions for self-deployment in mobile sensor networks with stochastic distribution of nodes. To overcome the connectivity maintenance and nodes stacking problems in the traditional virtual force ...

Improved FTA methodology and application to subsea pipeline reliability design. [PDF]

PLoS ONE, 2014
An innovative logic tree, Failure Expansion Tree (FET), is proposed in this paper, which improves on traditional Fault Tree Analysis (FTA). It describes a different thinking approach for risk factor identification and reliability risk assessment.

The complex channel networks of bone structure

, 2004
Bone structure in mammals involves a complex network of channels (Havers and Volkmann channels) required to nourish the bone marrow cells. This work describes how three-dimensional reconstructions of such systems can be obtained and represented in terms ...

Physics-Data Fusion Enhanced Virtual Synchronous Generator Control Strategy for Multiple Charging Stations Active Frequency Response

World Electric Vehicle Journal
In regions where electric vehicles (EVs) are widely adopted and charging stations (CSs) are being built in large numbers, CSs are becoming a critical load-side resource for low-inertia power systems.

Chaotic saddles in nonlinear modulational interactions in a plasma

, 2012
A nonlinear model of modulational processes in the subsonic regime involving a linearly unstable wave and two linearly damped waves with different damping rates in a plasma is studied numerically. We compute the maximum Lyapunov exponent as a function of

A Model-Based Approach for Bridging Virtual and Physical Sensor Nodes in a Hybrid Simulation Framework [PDF]

Sensors, 2014
The Model Based Design (MBD) approach is a popular trend to speed up application development of embedded systems, which uses high-level abstractions to capture functional requirements in an executable manner, and which automates implementation code generation.
