Smart Cities are the most challenging and promising technological solutions for absorbing the increasing pressure of population growth, while simultaneously enforcing a sustainable economic progress as well as a higher quality of life. Several technologies are involved in a potential Smart City deployment, although data are the fuel to achieve the demanded and mandatory smartness. Data can be obtained...
On the Internet of the future, billions of physical objects will collect and exchange data that will be stored in the Cloud Computing. A bad storage structure of big data has a negative influence on the latency time during the client's requests. To solve this problem, we have proposed an Infrastructure as a Service (IaaS) for the input and the output of different files on servers' clusters. We have...
With the development of flash technology, multilevel per cell (MLC) NAND flash memory has mastered the key market because of its storage capacity superiority. However, excessive density increment leads to decay of reliability of MLC NAND flash memory, thus an appropriate error correction code (ECC) is required to address this issue. This paper presents an efficient multi-strategy ECC scheme called...
Understanding human behavior is central to many professions in engineering, health and the social sciences, and has typically been measured through surveys, direct observation and interviews. However, these methods are known to have drawbacks, including bias, problems with recall accuracy, and low temporal fidelity. Recently, a new tool has been employed to great effect: the smartphone. Modern mobile...
The Internet of Things (IoT) is an emerging technology that is considered by industry and academy as a global infrastructure for the information society in today's digital world. IoT is implemented now in several ecosystems to improve economic indicators and productivity of enterprises, and also to improve the quality of consumer's lives. Thus a development of new architectures and approaches for...
The main idea behind Elders-Up! project is to bring the valuable experience of senior adults to start-ups and small companies [1]. The Elders-Up! project will build an ecosystem for collaboration on which European seniors' labour activities continue after retirement, as well as their productivity and usefulness to the society. On the other hand, small companies struggle to create their own production...
Software architecture description has been the subject of intensive research in the last two decades resulting in different formal ADLs applied for describing static and dynamic software architectures of (often large) single systems. However, none of these ADLs has the expressive power for formally describing the evolutionary architecture of a System-of-Systems (SoS). Recently, a novel ADL, called...
this paper presented the design of a data acquisition system for Cellular Impedance Measurement (CIM) application. The hardware architecture of the system mainly consists of a micro electrode array, a stimulation circuit, a sensing circuit, a multi-function card and a PXI-E based Chassis. The test results prove that the proposed system has excellent phase accuracy (error <0.05%) and magnitude accuracy...
Cyber-Physical System (CPS, shortly) is a fusion systems of computing and physical processes. It is a highly integration of computation, communication and control in the framework of networked embedded system. In this paper, we analyze the concept and feature of CPS and propose a graphical hierarchical architecture for CPS. It is a graphic network structure within the same layer and a hierarchical...
A multimedia wireless sensor network, a routing protocol plays an important role in saving the limited resources of sensors. It allows a node to transmit a multimedia content to the sink node, an image in our case. Also, WMSN are used in Internet of Things to serv different purposes in order to make our world smarter. In this paper, we are going to use the Castalia simulator to test different configurations...
The development of intelligent systems to support maritime situation awareness is the main goal of the SEAGULL project. By equipping unmanned aerial vehicles (UAVs) with different types of optical sensors we target an intelligent maritime surveillance system. In this paper we present experiments performed with an hyperspectral camera to detect oil spills. We have developed a detection algorithm that...
L-band Digital Aeronautical Communication System (LDACS) is an emerging standard that aims at enhancing air traffic management by transitioning the traditional analog aeronautical communication systems to the superior and highly efficient digital domain. The standard places stringent requirements on the communication channels to allow them to coexist with critical L-band systems, requiring complex...
Creating autonomy for maritime vehicles that allows multiple developers and users to quickly integrate and develop capabilities is a difficult process. Multiple examples of autonomy exist; however, creating an environment that is modular and expandable is not often a goal of many autonomous systems. This work presents an advanced Autonomous Vehicle Architecture (AVA) for maritime systems that was...
Assembly processes are a particular class of production processes that have gained increasing importance as to their impact on flexibility and efficiency of the overall process. Assembly processes are characterized by high variability concerning the type and logical flow of tasks to be performed, the devices and tools used, the materials and information to be processed. Due to the complexity of such...
Emergency situations, such as fire incidents or terrorist attacks, have imposed strongest safety requirements for crowds gathering. The enhancement of situation awareness, decision support and emergency notification systems that facilitate the safety and effectiveness of evacuation processes in a major incident is therefore of utmost importance. ICT, IoT and smart systems have gained much attention...
This paper tackles the networked distributed observer and controller design problem. The observers are designed in a distributed fashion. The computation effort due to high dimension of the whole system is then mitigated. The controllers are designed using linear quadratic regulation theory. A sufficient condition to guarantee the stability of the closed-loop system is derived. A conservative matrix...
Enterprise architecture modeling and model maintenance are time- consuming and error-prone activities that are typically performed manually. This position paper presents new and innovative ideas on how to automate the modeling of enterprise architectures. We propose to view the problem of modeling as a probabilistic state estimation problem, which is addressed using Dynamic Bayesian Networks (DBN)...
Next Generation Networks (NGN) principle or 5G technology, is based on the integration of heterogeneous wireless systems and cognitive networks. NGN is expected to have Quality of Service (QoS) as the major challenging issue. More specifically, NGN aims at providing guaranteed QoS levels and Quality of Experience (QoE), especially for multimedia services. However, with the increase in number of connections,...
We propose a data-centric three leveled modeling architecture in an effort towards a Model Driven approach of services for the Internet of Things (IoT): a resources level, an artifacts level and a semantic level. In this architecture, the resources level abstracts all important pieces of information describing real objects as resources. The artifacts level allows to collect all objects and contexts...
