Distributed algorithms and multi-agent systems have been studied in Smart Grid research for several years to address the problems arising from the integration of a substantial amount of distributed energy units. To change the role of these units from an uncontrolled feed-in behavior to actively contributing to system stability, efficient control system integration and scalability are important requirements...
Based on recent experimental discoveries about a link between the length of exposure to formaldehyde and cancers of the lymphatic and hematopoietic systems, we present a low-cost and compact solution for monitoring formaldehyde in the environment by using electronic nose technology. This solution is centered on an array of gas sensors and a regression method. It has the potential to be deployment...
In a related work, the author developed an approach to support model-based system engineering (MBSE) which ensures the conformance to a standard metamodel such as UML, SysML, or NAF, with dedicated project ontologies in order to ease the understanding and creation of models. The proposed mix approach brings flexibility and opens perspectives to support MBSE via predefined templates. However, the usage...
The emergence of Systems of Systems (SoS) arrangements, with their high level of complexity, mainly due to the different characteristics of the individual systems and their integration into the respective SoS, has brought about new challenges in terms of Configuration Management (CM) in general, and change management in particular. Novel change management frameworks are needed to appropriately address...
This study is about the disastrous flooding of an Indian metropolitan area of Chennai when the rain had nearly broken the record of 100-years with 374 mm rain falling on December 1, 2015, virtually breaking the November monthly average of 407.4 mm in a day. This city with a population of approximately 6.7 million people came to a standstill. Astonishingly, one of the biggest software development hubs...
The school dropout is a not negligible phenomenon that, if not effectively contrasted, puts at risk the future of young people and expose them to greater risks of unemployement, poverty and social exclusion compared to peers with a good instruction level. In this paper we present AYO!, an extracurricolar laboratory aimed to contrast the high school dropout. AYO! is an acronym that means Assemble Your...
The paper describes a management model where a service provider (SP) maintains multiple protocol modules to exercise the infrastructure resources (e.g., bandwidth, storage, servers) under various environment conditions. Each protocol depicts a distinctive work-flow among the networked entities (i.e., message exchanges and task coordination), incurring a certain amount of resource use. Different levels...
As the Internet of Things (IoT) becomes more of a reality, there is an increasing number of wireless and wired devices that are connected to the Internet. Future generations of telecommunications networks must evolve to deal with the anticipated high demand of the radio spectrum. As telecommunications networks become more complex, modeling networks as complex systems that are flexible in the face...
The software industry has been embracing the multi-cloud infrastructure for the design and adaptation of complex and distributed software systems. This new hybrid cloud infrastructure makes it possible to mix and match platforms and cloud providers for various software development activities. There are several benefits of the multi-cloud infrastructure such as lower level of vendor lock-in and minimize...
Under the background of system-of-systems (SoS) counterwork, it is more apparent that the simulation modeling of the equipment should be domain-specific, formal, automatic and composable. Current equipment effectiveness simulation modeling approaches are mainly based on the methods and techniques from the modeling and simulation (M&S) community and software engineering community, and they are...
The exigency of data analysis has been accelerating for routine operations in organizations. Every organization gathers a large amount of heterogeneous data every day. Subsequently, they develop their current and future strategies based on the analysis of the collected data. However, most small and medium organizations have been dealing with two major issues in the field of data analysis: requirements...
This paper aims to present a methodology that helps improving systems modelling by using Process Integration and Design Optimization technologies. Then, the methodology has been applied on an automotive case study: the improvement of the hybrid vehicle TOYOTA PRIUS III modelling. This work has been carried out in the context of the international research program PLACIS (PLAteforme Collaborative d'Ingénierie...
Autonomous systems are expected to be capable of performing many core functions with little or no human intervention. Many of the other functions required for overall success, however, still involve human supervision, manual control, or direct performance by a human. This paper presents the conceptual framework known as operator role theory, and specifically the concept of executive control (rather...
The objective of this paper1 is to present a framework that helps small and medium enterprise to exploit their available informational space. While large enterprises contains dedicated information management departments and software, the actual software framework implementations lack orientation towards small and medium companies with fewer employees and smaller budget. We propose a framework implementation...
This paper is made within the context of the research UEFISCDI project no. 31/2014, “AIMMS — Application for Using Image Data Mining and 3D Modeling in Dental Screening”. The project is interdisciplinary and wants to build a system framework composed of several sub-systems: dental pathology recognition part, 3D printing part, user interface part. The main emphasis of this article regards the pathology...
Molecular dynamics facilitates the simulation of a complex system to be analyzed at molecular and atomic levels. Simulations can last a long period of time, even months. Due to this cause the graphics processing units (GPUs) and multi-core systems are used as solutions to overcome this impediment. The current paper describes a comparison done between these two kinds of systems. The first system used...
The effort to well define requirements early in a life cycle is one of the major challenges in engineering programs. Studies have shown that both technical and managerial factors influence requirements quality. However, despite the numerous requirements engineering techniques and methods, there is little knowledge of how to integrate them into a systematic requirements process that considers technical...
This paper describes a sensor network architecture developed for museum monitoring. The proposed solution is based on a distributed environment composed of small, nearly invisible measuring nodes that wireless connect to Arduino-based WiFi routers to reach a distributed cloud. Users can connect to the measuring system by using their smart-phones and can receive alerts and measurements in real-time...
Technical systems of tomorrow will go beyond current traditional mechatronic designs by incorporating inherent intelligence. This causes high demands on the product development process, such as the need for a comprehensive understanding of the system and consideration of the full product lifecycle. Systems engineering (SE) is an approach that has the potential to fulfill these requirements. However,...
