The scientific objective of this paper is to figure out an advanced platform for personnel supervision and maintenance tasks. It is very essential to improve safety, reduce errors and decrease the time needed for scheduled or sudden interventions in extreme environments, including features, methods and tools. Current technology is standalone and none of the available technologies are integrated in...
If companies want to tackle increasing complexity, they often take use of modular system architectures which are seen as important enabler for sharing standardized modules across different development projects. Although numerous examples in systems business can be found where companies established modular architectures, they still face difficulties to reuse standardized architectural elements in a...
Human capital is the collection of durable attributes of individuals in a society that enable the production and consumption of goods and services. These attributes include the knowledge, skills, and abilities of individuals (which facilitates production) and their beliefs, desires, and intentions (which facilitates consumption). The healthcare system in a society maintains human capital by preserving...
Last few years have witnessed an ever-increasing demand of border crossing, whose processing introduces the need to speed-up the clearance process at the Border Crossing Points (BCP). Automated Border Control (ABC) gates, or shortly e-Gates, can verify the identity of the travelers crossing the borders by exploiting their biometric traits, without the need of a constant human intervention. Biometric...
The purpose of this paper is to provide an overview of the activities performed in the Single European Sky ATM Research (SESAR) in supporting large scale system of systems engineering and providing elements to overcome experienced limitations for future projects.
A system-level design framework based on SystemVerilog and the standard Universal Verification Methodology is a valuable tool to handle system complexity, evaluate multiple system architectures and achieve best design optimization through the concurrent contribution of multiple designers. This paper is focused on the implementation of such a platform for HEP applications. The specific target are next...
Reliability assessment represent a key issue in any advanced technology application where the systems must satisfy high level of reliability in order to guarantee ambient, personnel and system safety. This paper is focused on Reliability Block Diagram (RBD) technique with the aim of providing a reliability prediction for complex systems. In particular the case study is focused on gas turbine auxiliary...
Mechatronic systems become widely used as onboard systems with the development of electric and hybrid vehicles, more-electric aircrafts, etc. to achieve critical missions such as the control of these systems. The synergistic aspect of mechatronic systems makes their design challenging to take into account all the interactions among components of different domains. The safety-critical aspect of these...
A model-based design workflow for embedded control systems can accelerate product development, improve performance, increase reliability, and reduce engineering cost. Several current technology trends are driving engineering organizations to establish model-based workflows that enable concurrent and collaborative engineering. In this way, embedded controls engineers can quickly develop reliable products...
The robotic servicing of satellites on-orbit will play an important role in extending their lifespan and mitigating space debris expansion. However, most maneuvers related to these goals present a set of unique challenges which are hard to assess in reality. On the other hand, a reliable prediction of the feasibility of servicing maneuvers is increasingly required. This paper presents a simulation-driven...
The advent of both Cloud computing and Internet of Things (IoT) is changing the way to conceive distributed systems. Nowadays, we can talk about IoT Cloud to indicate a new type of distributed system consisting of a set of smart IoT devices or sensors interconnected with a remote Cloud infrastructure, platform, or software. Energy sustainability in IoT Cloud providers offers new tempting business...
Recently, the application of water hydraulics has been increasing in many fields as shown in [1], [2], [3]. However, water hydraulic systems using servo/proportional valves have inherent disadvantages such as low energy efficiency and high installation cost, which prevent water hydraulics from applying widely. Water hydraulic variable displacement pump does not exist in the market and therefore supply...
In the development of intelligent mechatronic systems, a gap of tools and methodologies exists, when technical requirements meet physical behavior modeling. Consistency and pervasiveness between requirements, development and modeling is not fully achieved and more sophisticated methods are needed. In a first step, the meaning of requirements in terms of intelligent mechatronic systems is pointed out...
A generic simulation method within heterogeneous system modeling is proposed enabling multi-domain vibro-acoustic gear simulation of electro-mechanical drive trains. The modeling approach accounts for cross-domain system simulation and numerical vibro-acoustic analysis including vibration excitation, structure-borne noise transmission and airborne sound emission. Peripheral mechanisms allow conservative...
Two mega trends in product engineering require a re-thinking of established ways of working: The technical evolution to intelligent technical systems and the re-design of value creation networks, now integrating partners from all over the world. Due to this, there is a growing interest in the Systems Engineering (SE) approach. Yet, the implementation of SE in organizational structures is challenging...
Systems Modeling Language (SysML) is used to capture systems design as descriptive and analytical system models, which relate text-based requirements to the system design model and provide an infrastructure to support analysis and verification. However, SysML is not a methodology, nor a method. This opens-up discussions of how to utilize SysML provided infrastructure to successfully achieve analysis...
Improvised Explosive Devices (IEDs) are reported as the number one cause of injury and death for allied troops in the current theater of operation. Current stand-off technologies for Counter IED (CIED) tasks rely on robotic platforms that have not improved in capability over the past decade to combat the ever increasing threat of IEDs. While they provide operational capability, the effectiveness of...
To improve the precision and efficiency of reliability analysis of flexible mechanism, Two-step Extremum Response Surface Method (TERSM) of reliability analysis is proposed. Dynamics differential equations of the flexible mechanism were established by using the integrated modal method and the flexible multi-body system dynamics method. By using the Monte Carlo Method (MCM), the random sample values...
The directive 2006/42/EC sets out essential safety requirements that a machine manufacturer has to meet, before its products may be sold on the European market. The core procedure to meet the provisions of the directive is the so called risk assessment. At present, the risk assessment in the industrial environment is often carried out in an unsystematic way and isolated from the entire product development...
