SHIELD is an EU-funded project, targeting at the design and development of a novel cybersecurity framework, which offers security-as-a-Service in an evolved telco environment. The SHIELD framework leverages NFV (Network Functions Virtualization) and SDN (Software-Defined Networking) for virtualization and dynamic placement of virtualised security appliances in the network (virtual Network Security...
We are currently witnessing an evolution towards network virtualization and Software Defined Networking (SDN) paradigm. SDN permits the decoupling of the control and data planes of traditional networks, and offers flexible and programmable networks. Besides, the need for dynamic provisioning and composition of networking services leads to the deployment of software components on virtualized network...
This paper lays the foundation for the development of an innovative electro-mechanical actuator for flight-control surfaces. The main features of the enhanced system will be the introduction of new sensor types and health monitoring capabilities. A dedicated test bench has been developed in order to perform endurance tests, leading the mechanical components to failure. In this view, a Condition Monitoring...
Medical Cyber Physical Systems (MCPS) are lifecritical networked systems of medical devices. These systems are increasingly used in hospitals to provide high-quality healthcare for patients. However, MCPS also bring concerns about security and safety and new challenges to protect patients from acts of theft or malice. In this paper, we focus our investigation on a thorough understanding of threat...
With the increasingly application of discrete control software in automatic control field, the security and reliability of its behavior becomes even more essential. However, the traditional verification methods are of high complexity and poor flexibility, so the lightweight Runtime Verification becomes an alternative. In this paper, aiming at real-time properties in discrete control software, an improved...
Software reuse in the early stages is a key issue in rapid development of applications. This article introduces a metaprocess-oriented methodology based on the model reuse as software assets, and starting from the domain specification and analysis phases. The approach includes the definition of a conceptual level to adequately represent the domain and a reuse process to specify the metaprocess as...
Service Function Chaining (SFC) serves the traffic of a specific service along an ordered set of Service Functions (SFs). SFC uses Software Defined Networking (SDN) and Network Function Virtualization (NFV) technologies to reach the deployment and removal of SFC in an appropriate time with minimal costs. However, during the life time of deployed SFCs, the SFs are exposed to the risk of overloading,...
Medical eye surgery robots are supporting the surgery process in many ways, they primarily can help the surgeon during surgery procedure, they can provide valuable status information about the environment, about the patient and about the forthcoming steps of the surgical process, and by definition they need to protect the patient too. During eye surgery we can differentiate phases of the process and...
System landscapes within logistical scenarios is highly heterogenic. Adding specific mechanisms, e.g. to support planing, monitoring and analyses for fully electrical powered vehicles, could become a mess or at least a challenge. While our project Smart City Logistic (SCL) is trying to manage this extension for multiple logistic scenarios, other projects want to do comparable system extensions as...
It has been shown that up to 64 percent of personal computers in office buildings are left running during after-hours. Enabling power management options such as sleep mode is a straightforward method to reduce the energy consumption of computers. However, choosing the right timeout can be challenging. A sleep timeout which is too low leads to discomfort, whereas a timeout which is too high results...
Programmable Logic Controllers (PLCs) are specialized computing systems for the control and monitoring of distributed industrial devices. Aiming for a highly connected industrial Internet-of-Things (IoT) ecosystem, PLCopen OPC Unified Architecture (UA) specification has been released. This paper presents the implementation and evaluation of a PLCopen OPC-UA software component for industrial control...
More and more modern applications make use of natural language data, e. g. Information Extraction (IE) or Question Answering (QA) systems. Those application require preprocessing through Natural Language Processing (NLP) pipelines, and the output quality of these applications depends on the output quality of NLP pipelines. If NLP pipelines are applied in different domains, the output quality decreases...
As modern unmanned aerial systems (UAS) continue to expand the frontiers of automation, new challenges to security and thus its safety are emerging. It is now difficult to completely secure modern UAS platforms due to their openness and increasing complexity. We present the VirtualDrone Framework, a software architecture that enables an attack-resilient control of modern UAS. It allows the system...
This paper describes the software architecture and the implementation of a fully operational testbed that demonstrates the benefits of flexible, dynamic resource allocation with virtualized LTE-A nodes. The testbed embodies and specializes the general software architecture devised within the Flex5Gware EU project, and focuses on two intelligent programs: the first one is a Global Scheduler, that coordinates...
In internet of things (IT) environment, a sensor interface device is essential for data collection in wireless sensor network (WSN) system for water quality monitoring (WQM) as the water pollution is a critical issue globally. This paper presents the design of a WSN based reconfigurable smart sensor interface device for WQM system in an IoT environment. The system consists of Field Programmable Gate...
In this article, we evaluate existing open source Phasor Measurement Unit (PMU) and Phasor Data Concentrator (PDC) software systems and benchmark their performance and reliability with various database systems. We also evaluate usability of the PDC systems and to list additional feature for the system. Among two open source PDC software, we found that OpenPDC out performs other PDC software in terms...
This article shows the possibility of using renewable energy sources in order to improve energy efficiency, reduce greenhouse gas emissions and therefore prevent climate change. This article proposes a remote monitoring and control system with interfaces and data collectors. In addition to research, development, testing and use of renewable energies, it is also necessary to measure and track online,...
The abundance of activity trackers and biosignal sensors as well as the evolution of IoT and communication technologies have considerably advanced the concept of Quantified-Self. Nowadays there are several frameworks and applications that realize the concept, focusing though strictly on specific areas, from daily use to professional activities such as sport and healthcare. This work proposes a versatile,...
Measuring and monitoring the bio-parameters of patient is one of effective method to assist doctor during diagnosis and treatment now. This paper presents a research result about using the patient monitor devices in the hospitals today. Since, we proposed and designed a model of a wireless central patient monitoring system for the hospitals in Vietnam. From the single patient monitoring devices, the...
Web Archiving Integration Layer (WAIL) is a desktop application written in Python that integrates Heritrix and OpenWayback. In this work we recreate and extend WAIL from the ground up to facilitate collection-based personal Web archiving. Our new iteration of the software, WAIL-Electron, leverages native Web technologies (e.g., JavaScript, Chromium) using Electron to open new potential for Web archiving...
