The research presented here is framed in the area of the design of Advanced Driving Assistance Systems (ADAS), carried out in the so-called automotive V-Cycle. In particular we concentrated our effort at the Model In the Loop (MIL) level. Indeed we developed an additional component for the fuel consumption evaluation at the MIL stage. The developed component has been based on the combination of a...
Electrified guided vehicles are normally equipped with regenerative braking devices, while traction lines are supplied by non-reversible substation, thus allowing braking energy recovery only if nearby other vehicles are absorbing power. To enhance the effectiveness of regenerative braking, some energy storage can be installed along the line. Evaluation of its cost effectiveness requires time domain...
5G assisted driving applications demand the provision of centimetre-accurate positioning. Automated vehicles typically use several positioning systems, such as radars, cameras and sensors, in addition to Global Navigation Satellite Systems (GNSS). This is necessary to ensure integrity and reliability, as well as precise positioning. The deployment of 5G cellular networks along roads are envisaged...
In this paper, we propose a validation procedure of energy consumption patterns implemented in a steady-state railway system software simulator by using experimental measured data. The software tool is able to evaluate the energy supplied by the feeding line to move a metro vehicle implementing different speed profiles. In particular, we suggest a simply methodology aimed to calibrate the metro system...
Micro aerial vehicles, such as multirotors, are particularly well suited for autonomous monitoring, inspection, and surveillance, e.g., for doing inventory in large warehouses. Key prerequisites for efficient MAV inventory missions is time- and energy-efficient flight. Generated trajectories must assure the visiting of certain waypoints while preventing large deviations or overshoot, as these can...
This paper presents the design and simulation of an energy-based control strategy to stabilize a quadrotor described with unit quaternions and their axis-angle representation. The mathematical model is based on Euler-Lagrange formulation using a logarithmic mapping in the quaternion space. The proposed solution introduces a new approach: a quaternion-energy-based control, which introduces an energy...
This paper presents a refinable and customisable alternator model with its heterogeneous environment, all implemented in SystemC and SystemC-AMS. The virtual prototype can be configured easily, and the embedded software can be changed at any time. Experience has shown that the overall development time can be reduced. Indeed, with a high-level configurable description of the environment and a refinable...
Intelligent Transport System (ITS) shall be able to incorporate transparently and seamlessly a large number of different and heterogeneous traffic system, while providing communication access to vehicles with various Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communication for the development of a safety commuting service. Building a route forecasting system is a complex task, mainly...
The article presents a universal simulation model of the general unsignalized intersection consisting of three (T intersection) or four arms. Each arm can consist of up to 5 lanes. The model is based on gap acceptance theory which defines rules for entering the intersection. The simulation model is created using software Witness. The main advantage of the presented approach is that defining all the...
In this paper we first examine by simulations and measurements the electromagnetic influence of a ballistic protection structure surrounding an armored infantry vehicle. In particular the performances of a rooftop jamming antenna are analysed, in absence or in presence of the ballistic protection. After assessing the reliability and level of accuracy of the simulations, some jamming performance improvements...
A multi-carpooling model is proposed for the multi-vehicle carpooling problem in a distributed parallel computing environment. A two-stage stochastic optimization of the estimation of distribution algorithm solves the optimum of the multi-carpooling problem with a carpooling probabilistic matrix. A ridable matrix initiates the carpooling probabilistic matrix, and the carpooling probabilistic matrix...
Internet of Things (IOT), a notion of integrated and self-configuring devices, has pulled the attention of many researchers due to its surging popularity in recent years. Internet of Vehicles (IOV) is an important part of IOT when the prime focus is on vehicles as the underneath intelligent devices. The vehicle communication in IoV is being derived through Vehicular Ad-hoc Networks (VANETs). While...
In this paper, we propose a reputation computation mechanism based on Hidden Markov Model (HMM) in VANET. The proposed model computes reputation value on the basis on received messages in VANET. Hence, VANET is characterized by high mobility and dynamic topology, where the vehicles exchange messages among them to enhance driving conditions. Due to hard delay constraints imposed by the need of small...
A piezoresistive silicon based stress sensor has been demonstrated successfully as an effective tool to monitor the stresses inside electronic packages during various production processes. More recently, the sensor has been evaluated as a sensor for Prognostics and Health Monitoring (PHM) systems. This paper presents a systematic approach that evaluates its performance from the perspective of failure...
The accelerated growth of applications and services in intelligent transportation systems (ITS) are driven by interests from the public and private sectors. The intent to utilize the onboard resources, along with the advanced methods of managing the available computing capabilities in the conventional cloud, has led to the high popularity of Vehicular Clouds. Likewise in Vehicular Networks, vehicles...

Knowledge of a flow field is crucial to guide oceanic mobile sensing platforms; yet, existing regional ocean models provide insufficient spatial and temporal resolutions for precise guidance of mobile platforms. By combining computational ocean models with real-time data streams collected from mobile platforms, generic environmental models (GEMs) provide high-resolution predictions of ocean currents...
Underwater vehicle is an important tool in the exploration, survey and investigation of the ocean and have many scientific, military, and commercial applications.
