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)...
The advent of the Internet of Things (IoT) has proliferated the use of connected sensors to observe and control the world around us. Wireless Sensor Networks (WSN) are becoming ubiquitous tools that monitor their surroundings and also oftentimes provide actuation to affect the state of their environment. One of the key application domains for real-time monitoring and control is the freight railroad...
Fiber Optic Gyroscope (FOG) is a truly and unique solid state technology that allows compact, lightweight and accurate sensors technology to provide orientation and position with or without GNSS availability. The INS (Inertial Navigation Systems) realized is an autonomous system that can operates in absence of GNSS and is essential for airborne application where safety is involved (i.e. the system...
Cognitive Radio communication is foreseen as one of the possible candidates that can resolve spectrum scarcity currently faced by the upcoming wireless technologies. This scarcity can be solved by enabling secondary access to the licensed spectrum. The interference at the primary receiver can be avoided by employing a detector (spectrum sensing) at the Secondary Transmitter (ST). Energy detection...
Cognitive radio (CR) has emerged as one of the most promising candidate solutions to improve spectrum utilization for future wireless networks. A crucial requirement for future CR networks is the ability to sense wideband spectrum. Recently, compressive sensing (CS) has been proposed as a solution to replace high speed analog-to-digital converters. CS enables sub-Nyquist sampling for wideband spectrum...
The number of sensors, actuators and electronic control units present in cars have increased in the last few years. The Internet-of-Things (IoT) model has transformed modern vehicles into a co-engineered interacting network of physical and computational components. Vehicles have become a complex cyber-physical system where context detection has become a challenge. In this paper, we present a rule...
Obstructive sleep apnea (OSA) occurs in more than 4 % of the adult population. Diagnoses for OSA in sleep clinics are costly and more than half of those submitted to a sleep clinic do not have OSA. A simple, easy, and portable homebased monitoring system to evaluate who are in high-or low risk of suffering from OSA would be beneficial. The system must be able to identify individuals with a high pre-test...
Indoor positioning provides great convenience for people's daily life. So far, numerous techniques have been proposed to track human movement, such as TOA, AOA and RSSI. Usually, these methods measure position depending on installed cells. In this paper, we propose a lower limb motion-based indoor positioning approach. Four IMU sensors are attached on both legs, separately, in order to get lower limbs...
In this paper we analyze the security requirements of civil microdrones and propose a hardware architecture to meet these requirements. While hardware solutions are usually used to accelerate cryptographic operations and reduce their power consumption, we show that the latter aspect needs to be reviewed in the context of civil drones. Specifcally, adding cryptgraphic hardware to a flying device increases...
In this paper we present a large-area interactive mixed reality system where multiple users can experience an event simultaneously. Through the combination of a number of innovative methods, the system can tackle common problems that are inherent in most existing mixed reality solutions, such as robustness against lighting conditions, static occlusion, illumination correction, registration and tracking...
The goal is to create a balance between human and machine, to augment humans in their physical tasks, to support humans for their rehabilitation, to enhance the performance of a human surgeon, to reduce the burden on the operator of intelligent systems (robotics) in commanding these systems, and to provide for human security both in the battlefield and in the homeland. The overall intent is to enhance...
This paper presents a detailed, systematic procedure for developing a Micro Aerial Vehicle (MAV), which is capable of autonomous flight in GPS-denied environments. This MAV is designed for a gross weight of 490 g and flight endurance of 8 minutes. The hardware structure (including the sensors, processors, and mechanical components), the software architecture (including operating system, navigation,...
The concept of transform sensing was recently proposed to operate radars which consist of multiple antenna elements, for high efficiency and resolution. Using transform sensing, phase delays between and amplitudes of elements are no longer constant as in conventional phased array radars. The purpose is to produce any type of spatial sensing pattern that can be applied to the space for efficient sensing...
Generally falls may occur from moving or resting postures. This may include slipping from bed and fall from a sitting, or from running or walking. The pre-fall is a non-equilibrium state of human position that may lead to serious injuries, and may negatively impact the quality life condition, particularly for elders. Physical disabilities resulting from the fall incidences may lead to high costs involved...
Measurement Systems Analysis (MSA) is a challenge in an Automated Testing Environment (ATE). Currently, there is no standard procedure on performing a Test MSA, which can either be statistically weak by being too simplistic or be too complex that it makes it difficult to deduce conclusions. This project aims to create a standard Test MSA that generates statistically-sound conclusions without the need...
With the increasing popularity of the Internet of Things applications, investors are more willing to invest on small digital electronic products and seek business opportunities. At the same time, along with the improvement of the data processing method, people want to get more accurate data. This paper presents an application that using Arduino and Bluetooth electronic scale to connect to smart phones...
Many industrial application could benefit from the use of wireless sensor networks technology in safety critical context.

A designed set of practices for a general course of Automotive Electronics is presented. The practices have been designed using the ‘mbed’ environment with the LPC1768 microcontroller. These practices aim to address the interaction of a system based on microcontroller and a real time operating system, with sensors and actuators, including buses commonly used in vehicles and OBD-II diagnostic systems.
The popularity of the Internet of Things allows the existence of many connected devices and thus, the quantity of data available is higher. However, many data are unusable if they are alone or out of context but a combination of these data can be valuable. This idea is also present in the information gathered by the human senses. The human body uses the senses to gather data about the environment...
The devices running embedded applications tend to be battery-powered, and the energy efficiency of their operations is an important enabler for the wide adoption of the Internet-of-Things. Optimization of energy usage depends on modelling power consumption. A model-based simulation must consider parameters that depend on the device used, the operating system, and the distributed application under...
