Performance of LoRa technology: link-level and cell-level performance
2020
Abstract LoRa is a chirp spread spectrum technology that is becoming very popular for low-power wide-area networks, with high-density devices. In this chapter, we study the capacity of LoRa in rejecting different interfering signals. First, we analyze LoRa modulation numerically demonstrating that channel captures appear easily and that collisions between packets modulated with different spreading factors (SFs) are not uncommon. We validate such findings in experiments based on commercial devices and software-defined radios. Second, we model the network capacity obtainable in a typical LoRa cell: we show that high SFs can be seriously influenced by inter-SF collisions and that fading has a …
On a Roadmap to Biologically Inspired Cognitive Agents
2011
A new challenge is proposed for future intelligent artifacts based on biologically inspired cognitive architectures (BICA), called the BICA Challenge. Namely, it is proposed that a BICA agent can only be considered human-level intelligent if it can be accepted and trusted as an equal member (a “person”) by a human community. For example, an agent of this sort would be able to win a political election against human candidates.
XPL, a Presentation Language based on User Interface Design Pattern
2007
The great diversity of presentations in software applications deals with fulfillment of various type of graphic interface constructions related to different programming Languages. Moreover, in the Internet era html pages play a main role because of the increasing complexity of Web applications. In Software Engineering, the use of design patterns is proven remarkable for the design and reuse of software components. Visual Design. Patterns (ViDP) are useful to define interaction schemas between. user and computer. By the some token, visual design. patterns are useful to incorporate common interfaces of interaction, schemas between user and computer. This paper describes the eXtensible Present…
A general theoretical framework for designing cognitive architectures: Hybrid and meta-level architectures for BICA
2012
In this paper, we will discuss hybrid architectures in which different processing modules coexist and cooperate in a principled way. A fundamental and essential role is played by modules performing meta-computation, i.e., computation about computation itself. Meta-level architectures, therefore, become an essential complement of hybrid architectures for biologically inspired cognitive architectures (BICA). Engineering and modeling BICAs is a hard task due to the lack of techniques for developing and implementing their features. We propose a new concept of intelligent agent as a useful abstraction for developing BICAs and having means for representing all the involved entities together with …
Multi-Platform Agent Systems with Dynamic Reputation Policy Management
2011
Open, distributed multi-platform agent systems require new management approaches for resources and data secure access. In this paper a Jade-S based multi-platform agent system implementing dynamic reputation policy management is proposed. The implemented extension deals with biometrics, X-Security, DES cryptography and agent reputation. With more details, the proposed reputation management system helps to assess the agent's behavior and reliability, in order to select trusted agents. This is made possible by the knowledge that agents are able to acquire, over time, and that allows them to choose the best solution using own intelligence in total autonomy.
DC4CD
2017
In this article, we present Distributed Computing for Constrained Devices (DC4CD), a novel software architecture that supports symbolic distributed computing on wireless sensor networks. DC4CD integrates the functionalities of a high-level symbolic interpreter, a compiler, and an operating system, and includes networking abstractions to exchange high-level symbolic code among peer devices. Contrarily to other architectures proposed in the literature, DC4CD allows for changes at runtime, even on deployed nodes of both application and system code. Experimental results show that DC4CD is more efficient in terms of memory usage than existing architectures, with which it also compares well in te…
High-level Programming and Symbolic Reasoning on IoT Resource Constrained Devices
2015
While the vision of Internet of Things (IoT) is rather inspiring, its practical implementation remains challenging. Conventional programming approaches prove unsuitable to provide IoT resource constrained devices with the distributed processing capabilities required to implement intelligent, autonomic, and self-organizing behaviors. In our previous work, we had already proposed an alternative programming methodology for such systems that is characterized by high-level programming and symbolic expressions evaluation, and developed a lightweight middleware to support it. Our approach allows for interactive programming of deployed nodes, and it is based on the simple but effective paradigm of …
La lunga marcia verso la libertà sindacale del “comparto sicurezza”
2020
Il saggio analizza l’evoluzione dei diritti sindacali nel “comparto sicurezza” (forze armate e di polizia) all’insegna di una prospettiva multilivello: dopo una disamina delle fonti sovranazionali (convenzioni OIL, Cedu e Carta Sociale Europea) e del dettato costituzionale, la ricerca si sofferma sulla libertà sindacale di militari e poliziotti alla luce del quadro normativo e giurisprudenziale di riferimento. Nonostante dal finire degli anni ’70 l’ordinamento militare e quello della Polizia di Stato si siano progressivamente aperti ai diritti collettivi, permangono numerosi profili di criticità, come il regime di separatezza sindacale, il divieto di sciopero e la mancata emanazione di una …

2019
L'autore esamina il libro di Guy Davidov "a purposive approach to labour law", e sostiene la necessità di una chiara comprensione degli scopi del diritto del lavoro, per favorire il mantenimento dei livelli di protezione del lavoro, necessari in una società che abia fiducia nel futuro The author examines Guy Davidov's book"a purposive approach to labour law", and adfirms that it is paramount to understand clearly the purposes of labour law, in order to maintain the level of protection of workers, that are essential in a society with confidence in the future.
The Introduction of the “Balanced Budget” Principle into the Italian Constitution: What Perspectives for the Financial Autonomy of Regional and Local…
2013
This paper analyses the impact on regional and local authorities of Articles 117 and 119 of the Italian Constitution as amended by Constitutional Law no. 1/2012. In particular, it attempts to verify whether the new formulation of these constitutional provisions materializes the risk of a significant reduction in the financial autonomy of both Regions and Local Governments. With the constitutional reform the legislative competence of “harmonization of public account” has become an exclusive State competence, the “balanced budget” principle has been extended to Regions and local authorities and public borrowing has been broadly prohibited. What is the actual significance of the changes introd…
