Degradation prediction is important for safety related products to avoid failures. When the degradations of multiple parameters of a product is taken into account, traditional univariate degradation prediction method is not applicable, especially when the parameters are correlated. To cope with this problem, Mahalanobis distance is proposed, to combine multiple parameters into one unified index. Then...
Development of different type of robot has been widely conducted in last few decades. Different type of terrestrial robots such as wheel robot, humandroid robot, snake robot and so on can be found in the literature. On the other hand, studies on aerial robot have been getting popular within last several years. In this paper, we targets to combine a terrestrial robot and aerial robot to develop hybrid...
In Internet of Things (IoT) world, there can be many sensors deployed in a system, thus their costs must be considered during the system design and material selections, in order to support massive production and deployment. Design-To-Cost (DTC) is an effective technique for this situation. In Model-Based Design (MBD), DTC cost estimates are preferred to be generated from models as one of the parameters...
With the rapid development of ICTs, condition monitoring has been used as a key technology in the plant industries. For reliable condition monitoring, sensors should output same values under same conditions regardless of time, but the sensitivity of sensors is gradually changed due to several factors such as temperature, humidity, contamination, aging, and etc. This type of situation is called as...
This paper proposes the design of an adaptive e- learning system with gamification elements. In the context of the increasing need to keep learners motivated among so many distractions, our project aims to help a user acquire knowledge at his own pace, in a captivating environment and as flexible as possible. To achieve that the solution focuses on the course model, adaptive questions and a reward...
To facilitate system architecture development using DoDAF, we propose an architecture development methodology based on DoDAF 2.0 in this paper. First, based on experiences in practice, gaps between Operational Viewpoint (OV), Capability Viewpoint (CV) and System/Service Viewpoint (SV/SvcV) are analyzed. Second, to bridge the gaps, two architecture viewpoints, i.e. Information activity Viewpoint (IaV)...
A mechatronic system results form the integration of several components from different domains. The system's behavior is sensitive to the values of its parameters and variables. Be it small or large, a variation in these values can significantly influence the overall functioning of the system. To provide a high quality product, the fluctuations between actual and target values of parameters should...
This paper proposes an approach to construct effectiveness evaluation model semi-automatically based on system architecture such as Department of Defense Architecture Framework (DoDAF). The effectiveness evaluation index system is firstly generated based on architecture models including Capability Dependencies (CV-4), Capability to Operational Activities Mapping (CV-6), Operational Activity to Systems...
Engineering of medical informatics systems is a complex work because it is at the intersection of several critical domains, among which medicine, computer science, electrical engineering to mention just a few. One critical aspect of such systems is the interoperability of the different components. One key solution for the interoperability is the creation of good standards that will assure the interchange...
With the introduction of autonomous systems becoming more and more prevalent in modern society a major focus of research on Artificial Intelligence (AI) and Autonomous Systems (AS) ethics is becoming important. There are many questions in the public about how these AI/AS programs will make ethical decisions as well as what ethical issues will be dealt with at a developmental level. Darning AI/AS development,...
Most of the models proposed in the literature try to model failure rate functions and failure intensities by means of a single model with a reduced number of parameters. If this approach can be effective for controlled situations or simple models it may happen that new models should be introduced in order to describe more accurately the behavior of the cases where non-monotonic failure rate or intensity...
Over the last decades several technologies have been developed towards the distributed automation architecture for Smart Factories, however, these technologies have not been yet implemented in industry. Manufacturers are quite conservative in adopting new technologies because the vast majority of existing infrastructures already have constraints in place related to their investment capabilities and...
Companies of the engineer-to-order (ETO) business face various trends such as digitalization and globalization. These trends will radically impact our ways of engineering. The Engineering framework translates Dave Snowden's Cynefin framework [2] to the engineering world. Cynefin for Engineers allows structuring future ways of engineering and guiding ETO companies along their transformation of engineering...
Edutainment systems' Development is well documented in research papers, and its application has satisfying results in several knowledge areas. However, methods for multidisciplinary team management in immersive edutainment systems engineering were not found in the survey made. A qualitative evaluation of immersive edutainment systems' engineering was conducted aiming to achieve grounded theory that...
Simulation results are not representative of a real system behavior up to its model validation. Validation activity needs a model characterization to match real system and model parameters. This activity impacts more on mechatronics systems which are affected by both physical and control characterizations. This work deals with single bowden power window systems; it improves a system model, previously...
Chemical plant is a factory producing chemical goods through a continuous chemical reactions flow process in a set of equipment and apparatus. In this factory, equipment is the most crucial components in the whole life cycle of the plant encompassing planning, design, engineering, construction, commissioning, operation & maintenance (O&M) and disposal. According to the industrial statistics,...
