Salibandyn lajianalyysi ja valmennuksen ohjelmointi
2013
Tämän työn tarkoituksena on tutkia salibandyssä vaadittavia eri ominaisuuksia, kuten fysiologiaa ja psykologiaa. Ravinto-osuus käsittelee tärkeät perusperiaatteet, jotka lajin kannalta ovat tärkeitä. Tutkimus sisältää myös valmennuksen ohjelmointia ja miten se tulisi suunnitella joukkueurheilussa. Työ perustuu tieteellisiin julkaisuihin, haastatteluihin sekä henkilökohtaisiin kokemuksiin. Salibandy on vielä nuori laji ja kehittynyt varsinkin Suomessa lyhyessä ajassa yhdeksi suosituimmaksi liikuntamuodoksi. Salibandy on tällä hetkellä Suomen kolmanneksi suosituin palloilulaji jalkapallon ja jääkiekon jälkeen rekisteröityjen pelaajien mukaan mitattuna (yli 45000 lisenssipelaajaa) (Suomen Liik…
Experimental Observation of a Large Low-Frequency Band Gap in a Polymer Waveguide
2018
The quest for large and low-frequency band gaps is one of the principal objectives pursued in a number of engineering applications, ranging from noise absorption to vibration control, and to seismic wave abatement. For this purpose, a plethora of complex architectures (including multiphase materials) and multiphysics approaches have been proposed in the past, often involving difficulties in their practical realization. To address the issue of proposing a material design that enables large band gaps using a simple configuration, in this study we propose an easy-to-manufacture design able to open large, low-frequency complete Lamb band gaps exploiting a suitable arrangement of masses and stif…

Wpływ rozkładu widma promieniowania słonecznego na parametry multikrystalicznego ogniwa krzemowego
2014
W artykule opisano wyniki uzyskane z opracowanej aplikacji integrującej model rozkładu widma promieniowania słonecznego oraz model krzemowego monokrystalicznego ogniwa fotowoltaicznego. W ramach badań opracowano program - symulator widma promieniowania słonecznego wykorzystujący algorytmy i procedury numeryczne oparte na modelu SMARTS2. Ponadto, przygotowano aplikację pozwalającą na przeprowadzenie modelowania komputerowego zachowania się ogniw i analizę zmienności ich parametrów przy zastosowaniu różnych rozkładów spektralnych oświetlenia oraz różnych parametrów materiałowo-konstrukcyjnych ogniw PV. Z wykorzystaniem niniejszej aplikacji przeprowadzono szereg symulacji. Dokonano analizy zal…
Com los castells de nostra religió no sien per a sostenir hòmens bandolés ni metre en mal e bandositat los vassalls nostres e de nostra religió. Guer…
2013
Fins fa pocs anys, la historiografia havia analitzat la conflictivitat al món rural des del punt de vista de la lluita de classes. En aquest discurs només s’atenien els enfrontaments entre senyors i camperols, especialment els esclats violents que caracteritzen el segle XIV. Ara bé, els últims estudis han de posat de manifest l’existència de profundes divisions internes en les comunitats rurals i la presència d’una conflictivitat latent no solament entre senyors i llauradors, sinó també entre els mateixos pagesos. A banda dels enfrontaments individuals, com ocorre a les ciutats de la Mediterrània Occidental, a les comunitats rurals del Maestrat s’articulen bàndols encapçalats pels pagesos m…
Two‐sample problems in statistical data modelling
2010
A common problem in mathematical statistics is to check whether two samples differ from each other. From modelling point of view it is possible to make a statistical test for the equality of two means or alternatively two distribution functions. The second approach allows to represent the two‐sample test graphically. This can be done by adding simultaneous confidence bands to the probability‐probability (P — P) or quantile‐quantile (Q — Q) plots. In this paper we compare empirically the accuracy of the classical two‐sample t‐test, empirical likelihood method and several bootstrap methods. For a real data example both Q — Q and P — P plots with simultaneous confidence bands have been plotted…
A Telemetry, Tracking, and Command Antennas System for Small-Satellite Applications

Circularly polarized (CP) antennas are used in space applications for telemetry tracking and command (TT&
. Strategie e iniziative per il recupero e la valorizzazione: un bilancio sui centri storici siciliani
2020
The present contribution focuses on the strategies carried out to hinder depopulation and facilitate the recovery of the historical city centres in Sicily in the last fifty years. In particular, the essay analyses if the strategies and initiatives fostered in this field had been respectful of the physical characteristics of these small towns. Furthermore, the present study intends to assess if the improvement of the “quality of life” has been considered among the strategies carried out to contrast depopulation. The scarce efficacy of policies and strategies over the last fifty years, which emerges from this analysis, is partially due to the endemic inability of politicians and local communi…
On the use of composite indicators for mobile communications network management in smart sustainable cities
2020
Beyond 5G networks will be fundamental towards enabling sustainable mobile communication networks. One of the most challenging scenarios will be met in ultra-dense networks that are deployed in densely populated areas. In this particular case, mobile network operators should benefit from new assessment metrics and data science tools to ensure an effective management of their networks. In fact, incorporating architectures allowing a cognitive network management framework could simplify processes and enhance the network&rsquo
Characterization of IP-Based Communication for Smart Grid Using Software-Defined Networking
2018
The smart grid (SG) approach is based on a strong interaction between the network communication infrastructure and the power grid. Usually the management of the infrastructure is done by the distribution system operators (DSOs) that are worried about the increasing managing complexity due to the presence of increasing number of distributed energy resources and electrical vehicles. The use of software-defined networking (SDN) may simplify the network configuration and management for DSO, as highlighted from previous research works. The objective of this paper is to introduce and characterize an internet protocol (IP)-based communication architecture with specialized SDN bridges operating als…
