This paper presents YouPower, an open source platform designed to make people more aware of their energy consumption and encourage sustainable consumption with local communities. The platform is designed iteratively in collaboration with users in the Swedish and Italian test sites of the project to improve the design and increase active user participation. The community-oriented design is composed...
Smart Grid, a modern approach to electricity distribution, requires innovation on various fronts. Communication is a key component of Smart Grid applicability. To satisfy Quality of Service (QoS) needs when deciding on network structure and topology, especially in urban areas, artificial intelligence techniques may be applied. Techniques such as clustering methods or genetic algorithms are useful...
It is reported that residential buildings almost consumed around 30% of electricity generated among other sectors such as industry, commercial and public services etc. In developing countries considerable amount of people have no direct access to the national power grid or are encountered long power blackout. Therefore people in those countries are very limited to use of electricity for routine basic...
In the context of grid-connected prosumers with an integrated photovoltaic-battery system, imbalance is the difference between the hourly net energy measured at the point of delivery and the associated forecast. Besides contributing with the increasing of the self-consumption, batteries can also compensate for imbalances if opportunely operated. This paper proposes two strategies to operate batteries...
This paper focuses on a typical customer with a PV plant and a battery storage by the perspective of two EU members: Italy and Spain. The authors calculate the electricity bill of the considered customer in accordance with the respective legislative and regulatory frameworks. This calculation is a preparatory and preliminary activity for finding relevant differences, if any, that should not exist...
The paper describes a measurement campaign conducted at the Engineering Department of Astronautics, Electrical and Energetic, Sapienza University of Rome. Starting from measurement campaign, in the context of building an urban microgrid, a PV plant and a energy storage system has been proposed. The measurements were conducted in two relevant period of the year in order to know the power consumption...
3D object recognition and registration in computer vision applications has lately drawn much attention as it is capable of superior performance compared to its 2D counterpart. Although a number of high performing solutions do exist, it is still challenging to further reduce processing time and memory requirements to meet the needs of time critical applications. In this paper we propose an extension...
We propose a stereo vision based obstacle detection and scene segmentation algorithm appropriate for autonomous vehicles. Our algorithm is based on an innovative extension of the Stixel world, which neglects computing a disparity map. Ground plane and stixel distance estimation is improved by exploiting an online learned color model. Furthermore, the stixel height estimation is leveraged by an innovative...
This paper presents the usage of Internet of Things concept as a tool for retrofitting air conditioning systems. The proposed technology consists in an embedded system developed with an open-source hardware platform and connected through a wireless sensor and actuator mesh network. By learning commands from the air conditioner's remote control, the system is capable of implementing automatic control...
This paper conducts a series of evacuation trials to observe human behavior under different ship rolling angles modeled as a function of wind-wave dynamics. A velocity reduction model is then developed with the consideration of human characteristics, ship rolling angles and wind-wave dynamics. Based on the open source simulation software FDS Evac, the proposed model is implemented and validated through...
Cataract is one of the most prevalent causes of blindness in the industrialized world, accounting for more than 50% of blindness. Early detection and treatment can reduce the suffering of cataract patients and prevent visual impairment from turning into blindness. But the expertise of trained eye specialists is necessary for clinical cataract detection and grading, which may cause difficulties to...
This paper presents a matrix-based discrete event model to simulate, design and implement a model-based control algorithm, including model predictive control. The proposed formalism extends a previous one adding timing information. This feature allows the evaluation of performance indexes making the model useful in many industrial automation systems in presence of real time control specifications.
The widespread diffusion of low-cost computing devices, such as Arduino boards and Raspberry Pi, along with improvements of Cloud computing platforms, are paving the way towards a whole new set of opportunities for Internet of Things (IoT) applications and services. Varying degrees of intelligence are often required for supporting adaptation and self-management—yet, they should be provided in a light-weight,...
With the diffusion of sensors and smart devices, and the advances in connection technologies, the Internet of Things (IoT) has become a very popular topic. Because of the creation and expansion of new and existing sensor networks, the need to define a common standard for sensors' interfaces representation has arisen. Currently it is difficult to make different sensors and sensors' networks interoperate...
IoT can dramatically improve the quality of life of aged population. In this regard, Ambient Assisted Living (AAL) and Active and Healthy Aging (AHA) are fields with an enormous potential to benefit from the current growth of IoT within our society. We present SAFE-ECH, an innovative intelligent AAL open source system for monitoring nursing homes. SAFE-ECH creates an Ambient Intelligent environment...
The increasing interest about the environment and the conditions for a safe and healthy life require continuous monitoring of physical and chemical parameters in the urban areas as well as in specifically dangerous surroundings (proximity of plants and hazard sites). Aside from the important consideration about risk and protection of the monitoring crew, the costs of extensive, specialist operators...
While wireless sensor networks (WSNs) have been traditionally tasked with single applications, we have witnessed the emergence of multiapplication paradigms in the sensor network field such as Shared Sensor Networks and Virtual Sensor Networks. As the number of applications in a WSN increases, it also increases the WSN complexity and the amount of required transmitted messages. A major requirement...
