Univariate and multivariate properties of wind velocity time series

2009

We analyze the time series of hourly average wind speeds measured at 29 different stations located in Sicily, a region with a complex morphology. The investigation, performed from the univariate as well as the multivariate point of view, evidences that the statistical properties of wind at the single sites have features that are not reproduced by standard models and, thus, require specific modeling. Moreover, the synchronous evolution of wind velocity presents a cluster structure, obtained with different algorithms, that persists in the standard deviation too.

Świętowanie na ulicy. Orszak Trzech Króli w zimowym pejzażu miasta

2017

Autorka zainteresowała się formami kolędniczymi, związanymi ze Świętem Trzech Króli (6 stycznia): tradycyjną grupą kolędniczą – Trzej królowie, nowszą – kolędnikami misyjnymi oraz organizowanym od 2009 r. na ulicach wielu miast w Polsce Orszakiem Trzech Króli, czyli oryginalną procesją uliczną. To hałaśliwe wydarzenie uliczne wpływa na odmienny charakter uczestniczenia w religijnym „misterium”: czytelny jest tu aspekt uteatralnienia ceremonii religijnej (przebrani aktorzy pierwszo- i drugoplanowi, rekwizytem powszechnym są papierowe korony królewskie, budowa scen, na których odbywają się koncerty amatorskich i profesjonalnych zespołów). Przemarsz ulicami miasta księży i osób wierzących, nau…

Sparsity-aware multiple relay selection in large multi-hop decode-and-forward relay networks

2016

In this paper, we propose and investigate two novel techniques to perform multiple relay selection in large multi-hop decode-and-forward relay networks. The two proposed techniques exploit sparse signal recovery theory to select multiple relays using the orthogonal matching pursuit algorithm and outperform state-of-the-art techniques in terms of outage probability and computation complexity. To reduce the amount of collected channel state information (CSI), we propose a limited-feedback scheme where only a limited number of relays feedback their CSI. Furthermore, a detailed performance-complexity tradeoff investigation is conducted for the different studied techniques and verified by Monte …

Trajectory Design and Resource Allocation for Multi-UAV Networks : Deep Reinforcement Learning Approaches

2023

The future mobile communication system is expected to provide ubiquitous connectivity and unprecedented services over billions of devices. The unmanned aerial vehicle (UAV), which is prominent in its flexibility and low cost, emerges as a significant network entity to realize such ambitious targets. In this work, novel machine learning-based trajectory design and resource allocation schemes are presented for a multi-UAV communications system. In the considered system, the UAVs act as aerial Base Stations (BSs) and provide ubiquitous coverage. In particular, with the objective to maximize the system utility over all served users, a joint user association, power allocation and trajectory desi…

Wireless software and hardware platforms for flexible and Unified Radio and Network Control (WiSHFUL)

2022

In the last years, we have assisted to an impressive evolution of wireless technologies for short distance communication (like IEEE 802.11, IEEE 802.15.4. Bluetooth Low Energy, etc.) due to the need of coping with the heterogeneous requirements of emerging applications, such as Internet of things, the Industry 4.0, the Tactile Internet, the ambient assistant living, and so on. Indeed, for optimizing the technology performance in these scenarios, it is often required to support some forms of protocol adaptation, by allowing the dynamic reconfiguration of protocol parameters and the dynamic activation of optional mechanisms, or some targeted protocol extensions.In both cases, prototyping, tes…

The role of the agreement as a tool for management of property relations in cases of cross border marriages and civil unions/partnerships registered …

2021

The essay examines the role of the agreement as a tool for managing property relationships in crossborder marriages and registered partnerships, in light of EU Regulations 1103 and 1104 of 2016, on the property regimes of international married or registered couples. The main prerogative of such acts is the recognition of the parties? freedom to choose the court and the applicable law. The law governing the matrimonial property regimes, or the property consequences of registered partnerships, has universal scope. This agreement in the form envisaged, which is backed by the need for legal certainty and predictability of the applicable rules, means that the spouses, in family problems which ha…

Sustainable Supercapacitors Based on Polypyrrole-Doped Activated Biochar from Wood Waste Electrodes

2023

The synthesis of high-performance carbon-based materials from biomass residues for electrodes has been considered a challenge to achieve in supercapacitor-based production. In this work, activated biochar has been prepared as the active electrode material for supercapacitors (SCs), and an effective method has been explored to boost its capacitive performance by employing polypyrrole (PPy) as a biochar dopant. The results for physicochemical characterization data have demonstrated that PPy doping affects the biochar morphology, specific surface area, pore structure, and incorporation of surface functionalities on modified biochar. Biochar-PPy exhibited a surface area of 87 m2 g−1, while pris…

Discurso y participación política en Plaza Podemos

2017

El uso de Internet y de sus posibilidades de persuasión e interacción ha convertido a los ciudadanos en actores políticos. Internet y las nuevas tecnologías no son un medio más, sino el reflejo organizativo de la nueva cultura política del ciberactivismo. Esta investigación ofrece datos sobre las características que tiene esa interacción dentro de un proceso de movilización política. Se ha empleado la herramienta de organización subreddit Plaza Podemos para descubrir si su uso expansivo se muestra eficaz para los foros virtuales del debate político comunitario. Se han obtenido datos de 100 hilos discursivos publicados en Plaza Podemos entre el 23 de abril y el 30 de septiembre de 2015. Se c…
