Monitoring train integrity is a very important topic for economical, management and safety reasons. Knowing the localization, volume and other parameters is very valuable for most train and large industry companies. Current literature focuses on placing many sensors in a Wireless Sensor Network (WSN) around the train wagons, but do not take battery lifetime into perspective. With the increasing interest in industrial Internet of Things (IoT) applications, the connectivity and battery lifetime are very important parameters. In this paper, the vibrations measured on train wagons are analyzed in order to find the most optimal trigger point to wake up or to put the WSN in a deep sleep mode. This way, a large amount of power can be saved and extend the battery lifetime significantly. Furthermore, several Received Signal Strength Indicator (RSSI) measurements were performed to find the optimal Tx level and antenna topology for communication between different wireless sensor nodes on the train wagon. The proposed measurements show that an inexpensive accelerometer and a prefabricated antenna are perfectly usable in the WSN. RF measurements on the brakes results in an average Package Receive Rate (PRR) of approximately 92 % and an Average Received Power (ARP) of around −83 dBm starting from a Tx level of 4 dBm.

Localization of mobile robots is a key task for the implementation of autonomous robotic systems. Several technolo-gies have been explored with advantages and disadvantages to perform this task. Recently, RFID technology has been taken into consideration due to its low cost and practicality, giving rise to a new line of research. By exploiting the probability of detection, the received signal strength, or the phase of the tag replies, it is possible to get vehicle location information. Obviously, RFID technology shows pros and cons, and several precautions must be taken into account for real-systems deployment. This work aims to give an overview of advantages and challenges that RFID technology has to face to be used on a large scale in mobile-robotics applications.

In this paper a building-plant system consisting in a housing module with 3D printed walls and a wooden roof is simulated with the dynamic simulation software TRNSYS 18 in coupling with an electric heat pump mainly driven by the electricity of a photovoltaic plant. Energy flows characterizing the system are dynamically assessed and on an annual basis it is evaluated if the condition of nearly Zero Energy Building (nZEB) is reached. Two further indexes - called Building Level of Energy Autonomy (BLEA) and Building Level of Energy Exported (BLEE) - are also calculated to estimate the energy autonomy and the level of energy exported in the proposed configurations. A parametric analysis considering two peak powers for the photovoltaic system (6.12 kWp and 12.24 kWp) and different sizes for the battery (from 2.16 kWh to 25.92 kWh) are investigated. Results highlights that with both photovoltaic (PV) plant layouts a positive yearly energy balance is obtained. The energy dependence decreases progressively till a certain electric storage capacity (15.12 kWh and 17.28 kWh). Over these values the BLEA stabilizes around 94% and 97% with the smallest and largest dimension of the solar field, respectively. In these conditions 44% and 68% of the produced electricity is fed into the distribution grid.

Unmanned Aerial Vehicles (UAVs or drones) have been extensively applied in monitoring studies to address marine and terrestrial wildlife animals. The main advantages of UAV s are their operational flexibility and low cost. In the last few years, the need to safeguard and protect the population of cetaceans in the Gulf of Taranto (Northern Ionian Sea, Central-eastern Mediterranean Sea) has grown in importance, and the UAVs video-analysis systems meet this need. In particular, dolphins, which can be potentially harmed by human activities in this area, could benefit a lot from the use and the application of automatic systems, in terms of estimation of group size and abundance. The goal of this study is to develop an automated non-invasive system for the analysis of videos acquired by UAV s, devoted to the estimation of cetaceans group size and abundance. An automated system like the proposed one would allow having an immediate estimate of the number of the encountered cetaceans, onboard the vessel, to be compared with the estimation made by the Marine Mammal Observer (MMO) in charge or it would be a useful support system for the expert when he has to analyze the video in the laboratory. In this paper, as a case of study, the UAV s video-analysis system has been applied on videos acquired by a camera mounted on a drone, during surveys in the Gulf of Taranto. Two different models of machine learning were used, and both the trained models are able to solve the task well albeit with some limitations.

This work presents the design and the first advances of the EVAMED tool (Environmental Assessment of Buildings with a Life Cycle approach). Its objective is to assist the building stakeholders, mainly in Latin America, in the first design phases, for make buildings with a lower environmental impact throughout their life cycle. EVAMED's interface is friendly and intuitive, as it is aimed at a non-LCA expert user. The configuration of the project to be evaluated through EVAMED is done over a ‘wizard’ type process. The results are presented through interactive graphs that allow visualizing the potential environmental impacts from different approaches. This allows different types of evaluations to be carried out, for example, analyzing the building Carbon Footprint, the environmental impact of its use phase, or evaluating its complete life cycle. EVAMED is linked to 3D BIM models through a plug-in developed in DYNAMO. This allows to obtain the quantity of materials, either from a detailed model or from a simplified one. This feature allows the user to evaluate different construction systems for the modeled building without necessarily having made a detailed model. EVAMED uses information from various databases such as MEXICANIUH (regional database of life cycle inventories for Latin America), Environmental Product Declarations, and ECOINVENT V3. The user complements the configuration of the project by specifying the type of machines and transport used during the respective stages of its life cycle. A case study is presented where the carbon footprint of two housing proposals is analyzed where one of them considers the use of thermal insulation to improve energy efficiency during the operational stage. The case using thermal insulation reduces their life cycle carbon footprint by almost 40% compared to case who does not use it. This is due to the reduction in energy demand during the use phase, even though the carbon footprint is higher during the production phase due to the manufacture and transport of the thermal insulation. EVAMED represents a step forward in building sector sustainability, mainly in the Latin America region. Is a tool looking to facilitate the decision-making during the early stages of buildings design process, considering their energy and environmental performance throughout their life cycle.

Rapid urbanization and reduced natural landscapes notably contributed to the formation of the urban heat island effect and as a consequence rising cooling energy demand. Increasing the surface albedo of urban surfaces allows for reducing the amount of heat absorbed by reflecting a significant part of incident solar radiation. This study investigated the impact of local climate conditions and cooling materials on the energy consumption of the building stock located in the densely populated Gangnam district in Seoul. The analysis was accomplished through the CitySim simulation tool intended for predicting the energy consumption of the building stock and the Weather Research Forecasting (WRF) model which was used for developing atmospheric conditions representing the usage of materials with a higher surface albedo. The transfer function representing the relationship between simulated and real energy consumption (EC) was developed using linear regression analysis. The R-Square value varied in the range from 0.49299 to 0.59941. The validation of the WRF showed that the WRF slightly underestimated the air temperature; the RMSE value was equal to 1.235, while MBE was equal to −0.738.

There is an increasing convergence of IoT features in newly developed health devices, bringing with it both optimism and concern. While these devices have similar connectivity goals to other IoT devices, they do bring critical requirements inherent in the digital health domain. This includes safety, privacy, reliability, accuracy and most importantly user assurance and engagement. These requirements are not usually met in generalized IoT platforms and architectures. In this paper, we take a step back to analyze the additional requirements and constraints that must be met by these devices to form an acceptable and effective health IoT ecosystem. We present democratization, a requirement that helps consolidate the many companion apps and data cloud logins a user must manage on a daily basis. The safe and proper use of devices is also a key requirement to ensure accurate data, not noise, are provided by these devices, boosting confidence. Ensuring verified user identity and enabling meaningful and safe interactions between the user's various devices (referred to as IoTility) are also key requirements that we analyze in detail.

The maker movement is rapidly growing and evolving into a living instrument for urban planning and circular economy. At its core, collaborative spaces that offer a variety of services (i.e., networking, knowledge transfer, training, etc.) and equipment, are making their appearance, with several typologies such as fablabs, makerspaces, or techshops. These spaces are mainly focused on stimulating creativity and enabling transformation of ideas into actual products and solutions, while actively supporting social collaboration and circular innovation. Nevertheless, in most cases, innovation support is limited to project development, without being followed by support on commercialisation, access to funding, and in general the stimulation of entrepreneurship, leaving high market potential untapped. This study explores the design of a circular maker entrepreneurship programme that is directly executed from within a makerspace to provide training and mentoring on fundamental business aspects and entrepreneurial skills, while supporting access to funding and market-driven networking. The programme introduced is currently being deployed in seven makerspaces, in six EU countries, delivering some first insights on the sustainability of this endeavour, including key challenges, limitations and mitigation measures.

This paper presents a flexible, 3D-printed, passive UHF RFID tag, specifically designed to be applied on the safety vest of a worker to allow its identification. Usually, conventional in-lay tags, are not easily exploitable for this purpose, because they are particularly sensitive to the proximity of the human tissue, which perturbates their performance. For this reason, a flexible, thick, and low lossy substrate has been realized using a TPE filament suitable for 3D printing so to separate the antenna from the human body, while maintaining an acceptable level of comfort. The conductive parts have been realized using a conductive and adhesive nylon-based fabric from Adafruit™, which has been purposely shaped through a Graphtech ™ CE6000 cutting plotter. This tag has been conceived to be part of a smart tracking system developed within the SMARTGRID project, in collaboration with INAIL (Italian National Institute for the prevention of accidents at work).

This tag has been conceived to be part of a smart tracking system developed within the SMARTGRID project, in collaboration with INAIL (Italian National Institute for the prevention of accidents at work).","PeriodicalId":295373,"journal":{"name":"2022 7th International Conference on Smart and Sustainable Technologies (SpliTech)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131395524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research presented in this paper presents a framework with an algorithm intended for the development of complex technical systems during their operation in uncertain situations. It is based on the prediction of deviations in the behaviour of complex engineering systems with uncertain operating parameters relative to the behaviour of the same system with the predicted operating parameters. In this case, the unexpected behaviour of the system in a changing working environment is modelled with: the architecture model of a complex technical system and the behaviour model of the same technical system. The model of complex system architecture is based on a matrix representation of the system components using a component Design Structure matrix (DSM) component. A mathematical model with distributed parameters and a model predictive control (MPC) method is used to describe the behavioural model of a complex system. Observed system stability is also verified using the direct Lyapunov method. Bilateral mapping of the obtained data between these two models allows describing and modelling the system behaviour in uncertain situations. The recording of the behaviour of the created complex system is performed using the rules of fuzzy logic. For this purpose, the Adaptive-Network-based Fuzzy Inference System (ANFIS) is used. Verification of the research results was carried out on a real example of a complex technical system - an air handling unit.
