A Cloud-Oriented Indoor-Outdoor Real-Time Localization IoT Architecture for Industrial Environments
No full textLocalization services for precise and continuous monitoring of the locations of both humans and vehicles in industrial environments are among the most relevant applications in Industrial Internet of Things (IIoT) contexts, to maximize safety and optimize operational activities. Unfortunately, localization in industrial scenarios is particularly challenging because targets can generally move freely in both indoor and outdoor areas. In this paper, we propose a localization monitoring architecture based on a prototypical wearable IoT device equipped with Ultra-Wide Band (UWB), inertial, and GNSS/RTK technologies for seamless localization in heterogeneous environments. We focus on a Web of Things (WoT) approach, verifying suitability and limitations in a real use case scenario. Our approach shows that the proposed architecture can effectively enhance the safety of workers, detecting potentially dangerous events and triggering alarms (e.g., via smart buzzers or gas concentration warning devices) based on a cloud WoT architecture
UTravel: Smart mobility with a novel user profiling and recommendation approach
No full textThe exponentially growing availability of online information calls for personalized search and recommendation. Such systems provide recommendations typically based on user profiles built taking into account user actions. Not yet fully explored, is the domain of context-aware recommendation. In this article, we introduce a novel approach, where user profiling and context-based data filtering both concur to recommendation production. Based on the aforementioned approach, UTravel is a smart mobility application that recommends points of interest (POIs) to end users. After describing the UTravel architecture and implementation, we present the results of an experimental evaluation we carried out involving both simulated and real users
Ética y Humanitarismo: dimensiones morales de la ayuda humanitaria desde la perspectiva de Thomas Pogge
Full text linkEl problema de la pobreza global ha alcanzado proporciones gigantescas. Durante los últimos 20 años la cantidad de muertes por causa del hambre y por enfermedades que podrían ser evitadas han ascendido aproximadamente a 250 millones de personas. Thomas Pogge, sostiene que los Estados ricos tienen la responsabilidad de ayudar a aquellos que se encuentran sumidos en la pobreza severa. Esta responsabilidad –que podría entenderse también como un deber moral– resulta del daño, muchas veces evitable, que el orden institucional global actual ha perpetrado sobre Estados pobres. La existencia de la pobreza global, para este autor, constituye una clara violación de los Derechos Humanos.For the last 20 years the amount of deaths because of hunger and diseases that could be avoided affects approximately 250 million people. Thomas Pogge affirms that the rich countries have the responsibility to help the other countries that are sunk in severe poverty. This responsibility –that could also be understood as moral duty– comes from the damage, often avoidable, that the present global institutional order has perpetrated upon poor States. Global poverty, according to this author, is a clear violation of the human rights, as well as a crime towards humanity.Fil: Belli, Laura Florencia. Universidad de Buenos Aires. Facultad de Medicina.

Enhancing Security in a Big Stream Cloud Architecture for the Internet of Things Through Blockchain
No full textThe Internet of Things (IoT) paradigm is foreseeing the development of our environment towards new enriched spaces in most areas of modern living, such as digital health, smart cities, and smart agriculture. Several IoT applications also have real-time and low-latency requirements and must rely on specific architectures. The authors refer to the paradigm that best fits the selected IoT scenario as “Big Stream” because it considers real-time constraints. Moreover, the blockchain concept has drawn attention as the next-generation technology through the authentication of peers that share encryption and the generation of hash values. In addition, the blockchain can be applied in conjunction with Cloud Computing and the IoT paradigms, since it avoids the involvement of third parties in a broker-free way. In this chapter, an analysis on mechanisms that can be adopted to secure Big Stream data in a graph-based platform, thus delivering them to consumers in an efficient and secure way, and with low latency, is shown, describing all refinements required employing federation-based and blockchain paradigms
Patentes sobre los genes BRCA-1 y BRCA-2: El caso Myriad
Full text linkEl número de patentes sobre materiales biomédicos y procesos, como líneas celulares, métodos de replicación y pruebas genéticas está aumentando día a día. Quienes están a favor de la concesión de este tipo de permisos sostienen que estas patentes poseen ciertas ventajas, tales como proporcionar los fondos necesarios para desarrollar y distribuir las terapias necesarias de estas investigaciones realizadas a partir de ellas. Aquellos que se oponen a que se otorguen esta clase de patentes argumentan que las mismas generan graves problemas de justicia en salud, como el aumento desmedido del costo de los tratamientos, lo cual los vuelve inasequibles a los más pobres. El presente trabajo se propone analizar las patentes otorgadas a Myriad sobre los genes BRCA1 y BRCA2 las que presentan una serie de cuestiones técnicas y éticas relacionadas con su legitimidad.Fil: Belli, Laura Florencia.

Hyperledger Fabric in Precision Agriculture: A Study on Data Integrity and Availability
No full textThe increasing severity of weather events and growing demands for food pose significant challenges to farming and agricultural activities. Over the past decades, the deployment of data acquisition and Internet of Things (IoT)-oriented technologies has emerged as a relevant solution to face these issues, with a primary reason behind this digital agricultural revolution being the cost-effectiveness of data collection in various areas (e.g., soil conditions, crop development, weather patterns). On the basis of these technological advancements, in this paper we discuss on a fully-distributed blockchain-based IoT-oriented agricultural monitoring system based on an integrated Hyperledger Fabric framework. The proposed platform is designed to maximize the efficiency of the approach, to analyze several potential benefits (including, as an example, possible increased food production on reduced land areas, with lower input requirements and a diminished environmental impact), and to effectively aggregate and interpret data into actionable insights for farmers and policymakers. We then propose a preliminary system's deployment, which is instrumental to reflect on platform's scalability, inclusiveness, and modularity. The obtained results highlight its suitability to enhance precision agriculture with secure tracking features
An Edge Computing-Oriented WoT Architecture for Air Quality Monitoring in Mobile Vehicular Scenarios
No full textNowadays, the need to efficiently process information in Internet of Things (IoT)-oriented heterogeneous scenarios has increased significantly, e.g., in all scenarios where unobtrusive environmental monitoring is beneficial for the involved people (e.g., inside public transport vehicles, indoor workplaces and offices, large public infrastructures, etc.). This objective typically requires the combination of heterogeneous IoT systems, which need to efficiently share information, e.g., through the Web of Things (WoT) paradigm. In this paper, we propose an edge computing-oriented flexible WoT architecture, with distributed intelligence, for air quality monitoring and prediction inside a public transport bus. Our results show that the proposed architecture allows seamless integration of heterogeneous IoT systems according to a WoT perspective, exploiting the device/edge/fog computing continuum and using containerized and secure processing modules

No full textThe value creation through production is currently shaped by Industry 4.0, whose paradigm aims at improving industry management and business processes. Through a case study, this research describes the renovation steps, in a manufac-turing environment. The research aims to study how the introduction of digital in-novation helps in making more efficient and time saving production (RQ1), as well as in increasing product quality, enabling on time detection of non-conformity (RQ2). At theoretical level, the research aims to close the gap between the Internet of Things (IoT) application and real-word aspects, analyzing how an industry 4.0 transformation could be modelled and implemented. At managerial level, the study shows how IoT technologies and process digitalization should provide ad-vantages in terms of cost reduction, product quality control, allowing continuous collection of heterogeneous data useful to optimize the production further
