Performance of LTE-V2V for Cooperative Awareness

The large scale development of an Intelligent Transportation System is very close. The main component of such a smart environment is the network that provides connectivity for all vehicles. Public safety is the most demanding application because requires a fast, reliable and secure communication. Although IEEE 802.11p is presently the only full wireless standard for vehicular communications, recent advancements in 3GPP LTE provide support to direct communications and the ongoing activities are also addressing the vehicle to vehicle case. This thesis focuses on the resource allocation procedures and performance of LTE-V2V. To this aim, a MATLAB simulator has been implemented and results have been obtained adopting different mobility models for both in-coverage and out-of-coverage scenarios.

Distributed non-cooperative robust economic predictive control for dynamically coupled linear systems.

In this thesis, a tube-based Distributed Economic Predictive Control (DEPC) scheme is presented for a group of dynamically coupled linear subsystems. These subsystems are components of a large scale system and control inputs are computed based on optimizing a local economic objective. Each subsystem is interacting with its neighbors by sending its future reference trajectory, at each sampling time. It solves a local optimization problem in parallel, based on the received future reference trajectories of the other subsystems. To ensure recursive feasibility and a performance bound, each subsystem is constrained to not deviate too much from its communicated reference trajectory. This difference between the plan trajectory and the communicated one is interpreted as a disturbance on the local level. Then, to ensure the satisfaction of both state and input constraints, they are tightened by considering explicitly the effect of these local disturbances. The proposed approach averages over all possible disturbances, handles tightened state and input constraints, while satisfies the compatibility constraints to guarantee that the actual trajectory lies within a certain bound in the neighborhood of the reference one. Each subsystem is optimizing a local arbitrary economic objective function in parallel while considering a local terminal constraint to guarantee recursive feasibility. In this framework, economic performance guarantees for a tube-based distributed predictive control (DPC) scheme are developed rigorously. It is presented that the closed-loop nominal subsystem has a robust average performance bound locally which is no worse than that of a local robust steady state. Since a robust algorithm is applying on the states of the real (with disturbances) subsystems, this bound can be interpreted as an average performance result for the real closed-loop system. To this end, we present our outcomes on local and global performance, illustrated by a numerical example.

Nòmasi: un servizio per nuove comunità nomadi sinergiche e cooperative.

Lo scenario contemporaneo con il dirompente progresso tecnologico, i considerevoli mutamenti socio-sanitari post-pandemici, politici e culturali in atto è pervaso dall’impellente esigenza di ricercare e sperimentare stili di vita alternativi, più liberi e autonomi. Il nomadismo è un fenomeno in crescente aumento. Alla base del nomadismo riscontriamo tematiche trasversali quali la semplicità volontaria e il minimalismo, una maggiore capacità di ascolto e di attenzione verso il prossimo, queste si pongono in opposizione ai condizionamenti sociali e all’omologazione che caratterizzano lo scenario contemporaneo. La ricerca di tesi pone le basi sulla comprensione del nomadismo nella storia dell’evoluzione umana, degli aspetti socio-culturali e antropologici della figura nomade, dell’evoluzione dell’architettura mobile e infine trattando il recente fenomeno dei nomadi digitali. Il progetto di servizio è il risultato dell’applicazione delle metodologie del Service Design, di Design Thinking e di Human Centred Design applicate all’ambito di ricerca degli stili di vita nomadi. Nòmasi si propone come un servizio per nuove comunità nomadi sinergiche e cooperative. Con il seguente progetto di servizio si propone di soddisfare, in maniera innovativa, i bisogni emersi durante la fase di ricerca a sostegno di stili di vita che spesso vengono ritenuti marginali ed erroneamente associati a scenari di degrado, poichè distanti dalle dinamiche di incasellamento sociale caratteristiche della società stanziale. Nòmasi consiste in una rete di orti sinergici radicata in maniera diffusa sul territorio Italiano che permetta, attraverso le tecniche di coltura sinergica e la conversione del tempo dedicato a questi spazi in monete virtuali, di aumentare l’autonomia alimentare degli utenti creando sinergia tra gli utenti. L’elaborato di tesi si conclude con la definizione dei touchpoint, stabilendo il funzionamento della piattaforma digitale e l’interazioni degli attori.

Modeling, simulation, and control of a formation of multirotor aircraft for cooperative transportation of suspended loads

The work presented in this thesis aims to contribute to innovation in the Urban Air Mobility and Delivery sector and represents a solid starting point for air logistics and its future scenarios. The dissertation focuses on modeling, simulation, and control of a formation of multirotor aircraft for cooperative load transportation, with particular attention to environmental sustainability. First, a simulation and test environment is developed to assess technologies for suspended load stabilization. Starting from the mathematical model of two identical multirotors, formation-flight-keeping and collision-avoidance algorithms are analyzed. This approach guarantees both the safety of the vehicles within the formation and that of the payload, which may be made of people in the very near future. Afterwards, a mathematical model for the suspended load is implemented, as well as an active controller for its stabilization. The key focus of this part is represented by both analysis and control of payload oscillatory motion, by thoroughly investigating load kinetic energy decay. At this point, several test cases were introduced, in order to understand which strategy is the most effective and safe in terms of future applications in the field of air logistics.

Studio, Progettazione e Sviluppo di Applicazioni di Realtà Mista Cooperative

Le esperienze cooperative in realtà mista. Che cosa sono? Quali sono gli scopi dietro il loro sviluppo? Che cosa aspetta uno sviluppatore che si avvicina a questi sistemi? Questa tesi cerca di rispondere a queste domande ponendo sotto esame diverse tecnologie di collocazione molto recente, analizzando un progetto preso come caso di studio e implementato tramite diversi strumenti. Al giorno d’oggi, la sfera della realtà mista/realtà aumentata si sta espandendo sempre di più, arrivando a sfiorare mondi che prima risultavano totalmente scollegati. Il mondo dello sviluppo in ambito gaming è entrato infine in questo panorama grazie alle tante similarità con certi tipi di applicazioni MR. Uno degli strumenti più utilizzati in questo ambito è Unity, un motore grafico utilizzato per creare videogiochi e non solo: in questo progetto si sfrutterà questo ambiente di sviluppo per realizzare una semplice applicazione in realtà mista cooperativa, che permetta quindi l’accesso a più utenti contemporaneamente e la loro interazione. Per farlo, si valuteranno diverse opzioni, in particolare due, Netcode for GameObjects e Photon PUN, provenienti da due ambienti diversi ma entrambe strettamente legate a Unity, cercando di ottenere lo stesso risultato ma con due strade diverse come base per un confronto. Basteranno queste tecnologie o ci vuole ancora altro per la realtà mista? Questo studio trova una base matura e pronta a uscire dal suo guscio? Oppure c’è ancora tanta strada da fare? Sulla base di questo verrà tenuto il confronto, cercando una risposta generale ma concreta. Questa tesi si dividerà in due parti: la parte introduttiva, che fornirà tutti i concetti sulla realtà mista necessari e un panorama sull’ambiente MR in generale. La seconda, invece, servirà a illustrare quali sono le sfide di uno sviluppo in questo mondo, usando un progetto applicativo come soluzione a queste sfide o almeno ad una loro parte.

Identification Of Corynebacterium Spp. Isolated From Bovine Intramammary Infections By Matrix-assisted Laser Desorption Ionization-time Of Flight Mass Spectrometry.

Corynebacterium species (spp.) are among the most frequently isolated pathogens associated with subclinical mastitis in dairy cows. However, simple, fast, and reliable methods for the identification of species of the genus Corynebacterium are not currently available. This study aimed to evaluate the usefulness of matrix-assisted laser desorption ionization/mass spectrometry (MALDI-TOF MS) for identifying Corynebacterium spp. isolated from the mammary glands of dairy cows. Corynebacterium spp. were isolated from milk samples via microbiological culture (n=180) and were analyzed by MALDI-TOF MS and 16S rRNA gene sequencing. Using MALDI-TOF MS methodology, 161 Corynebacterium spp. isolates (89.4%) were correctly identified at the species level, whereas 12 isolates (6.7%) were identified at the genus level. Most isolates that were identified at the species level with 16 S rRNA gene sequencing were identified as Corynebacterium bovis (n=156; 86.7%) were also identified as C. bovis with MALDI-TOF MS. Five Corynebacterium spp. isolates (2.8%) were not correctly identified at the species level with MALDI-TOF MS and 2 isolates (1.1%) were considered unidentified because despite having MALDI-TOF MS scores >2, only the genus level was correctly identified. Therefore, MALDI-TOF MS could serve as an alternative method for species-level diagnoses of bovine intramammary infections caused by Corynebacterium spp.

Bacterial Killing Via A Type Iv Secretion System.

Type IV secretion systems (T4SSs) are multiprotein complexes that transport effector proteins and protein-DNA complexes through bacterial membranes to the extracellular milieu or directly into the cytoplasm of other cells. Many bacteria of the family Xanthomonadaceae, which occupy diverse environmental niches, carry a T4SS with unknown function but with several characteristics that distinguishes it from other T4SSs. Here we show that the Xanthomonas citri T4SS provides these cells the capacity to kill other Gram-negative bacterial species in a contact-dependent manner. The secretion of one type IV bacterial effector protein is shown to require a conserved C-terminal domain and its bacteriolytic activity is neutralized by a cognate immunity protein whose 3D structure is similar to peptidoglycan hydrolase inhibitors. This is the first demonstration of the involvement of a T4SS in bacterial killing and points to this special class of T4SS as a mediator of both antagonistic and cooperative interbacterial interactions.

O papel da interação no processo de ensino-aprendizagem de português para alunos surdos em uma escola inclusiva

In this article, it is discussed the role of interaction in the process of teaching and learning Portuguese of deaf students at an inclusive school. In the context where the research took place, the hearing teacher does not understand sign language, and there are, in her classroom, hearing students and four deaf students, being three of them sign language users. As the communication between the hearing teacher and the deaf students occurred in different codes - Portuguese and Brazilian sign language - and having a social-interactional approach of language (MOITA LOPES, 1986; FREIRE, 1999), we observed if the interaction among the subjects enabled the deaf students to understand what was being taught. The results showed that the fact of having four deaf students in the same classroom allowed them to work in a cooperative way. Besides, the sign language became more visible in this institution. On the other hand, the interaction between the teacher and her deaf students revealed to be of little significance to the learning process of this small group.
