Kierunki modernizacji sieci kolejowej

2017

Opracowanie przedstawia kierunki modernizacji sieci kolejowej Polski w latach 2003-2017. Długość sieci kolejowej w kraju ulega zmniejszeniu. Zachodzi proces likwidacji linii i zawieszenia przewozów kolejowych. W kraju modernizowane są główne linie magistralne. Na modernizację składają się: wymiana torów, przebudowa trakcji elektrycznej i wprowadzenie nowoczesnych systemów sterowania ruchem i sygnalizacji (ECTS). Przebudowie ulęgają linie kolejowe o znaczeniu tranzytowym zaliczane do europejskiego układu połączeń kolejowych w ruchu pasażerskim (umowa AGC) i towarowym (umowa AGTC). Projekty modernizacji linii kolejowych są finansowane ze środków europejskich i krajowych. Główne źródła finanso…

Application of selected supervised classification methods to bank marketing campaign

2016

Supervised classification covers a number of data mining methods based on training data. These methods have been successfully applied to solve multi-criteria complex classification problems in many domains, including economical issues. In this paper we discuss features of some supervised classification methods based on decision trees and apply them to the direct marketing campaigns data of a Portuguese banking institution. We discuss and compare the following classification methods: decision trees, bagging, boosting, and random forests. A classification problem in our approach is defined in a scenario where a bank’s clients make decisions about the activation of their deposits. The obtained…

Improving Scalable K-Means++

2021

Two new initialization methods for K-means clustering are proposed. Both proposals are based on applying a divide-and-conquer approach for the K-means‖ type of an initialization strategy. The second proposal also uses multiple lower-dimensional subspaces produced by the random projection method for the initialization. The proposed methods are scalable and can be run in parallel, which make them suitable for initializing large-scale problems. In the experiments, comparison of the proposed methods to the K-means++ and K-means‖ methods is conducted using an extensive set of reference and synthetic large-scale datasets. Concerning the latter, a novel high-dimensional clustering data generation …

Improvements and applications of the elements of prototype-based clustering

2018

Clustering or cluster analysis is an essential part of data mining, machine learning, and pattern recognition. The most popularly applied clustering methods are partitioning-based or prototype-based methods. Prototype-based clustering methods usually have easy implementability and good scalability. These methods, such as K-means clustering, have been used for different applications in various fields. On the other hand, prototype-based clustering methods are typically sensitive to initialization, and the selection of the number of clusters for knowledge discovery purposes is not straightforward. In the era of big data, in high-velocity, ever-growing datasets, which can also be erroneous, outl…

Il disegno per la salvaguardia dell’architettura: la Centrale Termoelettrica di Giuseppe Samonà a Trapani

2019

Riflessioni grafiche per salvaguardare l’architettura. Nella Centrale Termoelettrica di Giuseppe Samonà, costruita a Trapani negli anni ’60, il concetto di spazio non inteso come mero luogo di lavoro, le relazioni armoniche che il manufatto instaura con il paesaggio, il linguaggio come esito del dualismo tra involucro e struttura e la lezione dei maestri del ‘900 sono tutti caratteri estrinsecabili attraverso il ridisegno critico. Un atto ermeneutico che tenta di definire il valore dell’edificio e diffonderne la conoscenza, al fine di scongiurarne l’oblio o, ancor peggio, la distruzione. Graphic reflections to safeguard the architecture. In the Thermoelectric Power Plant of Giuseppe Samonà,…

Drawing techniques as tools for the evaluation of scholastic integration and emotional components in primary and secondary school : a cross-sectional…

2023

IntroductionIn the last decades, many studies have emphasized emotion’s role in psycho-educational processes during childhood, such as scholastic integration. Emotional variables in childhood can be assessed through projective graphic techniques, as they allow children to use kinetic components of the draws to communicate emotions.Method1.757 couple of draws were collected, from primary school children (N = 1.270; F = 643 [50.6%]; Age = 8.6; SD = 1.31) and secondary school children (N = 487; F = 220 [45.2%]; Age = 11.72; SD = 0.70) and from eight schools in Sicily and over 60 different classrooms. The Drawn Stories Technique and the Classroom Draw were used to assess children’s current emot…

La ricerca azione con progetto

2021

Sono svolte alcune considerazioni, di carattere metodologico, ricavate dalla riflessione su quelle ricerche empiriche, che sono state svolte negli ultimi quaranta anni nelle scuole italiane, con una doppia connotazione: la collaborazione paritaria tra un ricercatore di didattica e gli insegnanti in servizio e l’intento esplicito di migliorare alcune competenze professionali dei docenti, con il conseguente impianto di innovazioni didattiche nella scuola. E’ giustificata la procedura della ricerca azione con progetto (RAP), che cerca di contemperare l’esigenza di rigorosità della ricerca scientifica e la flessibilità imposta ai piani di ricerca dalla variabilità delle situazioni scolastiche. …

The angle of trunk rotation and symmetry of a lower limb loading in musicians of a symphony orchestra in Poland: a pilot study concerning instrument-…

2022

Background: The study aimed to evaluate the angle of trunk rotation (ATR) and symmetry of lower limb loading in professional musicians. Material and Methods: A total of 60 instrumentalists were examined: cellists, violinists and musicians playing wind instruments. The scoliometer examination was used to assess trunk asymmetry. The angle of trunk rotation was measured at segment: Th1–Th4, Th5–Th12, and Th12–L4. The maximum value (ATR max) and the sum of three rotations (STR) were calculated. Two scales were used to assess the symmetry of lower limb loading. Loading symmetry index (LSI) of the lower limb was calculated. Results: Violinists have the highest mean values of ATR, ATR max, STR and…

Information technologies have produced new ways of distributing and consuming music, mainly by youth, in relation to both goods and services. In the case of goods, there has been a dramatic shift from traditional ways of buying and listening to music to new digital platforms. There has also been an evolution in relation to music services. In this sense, live music concerts have been losing their audiences over the past few years, as have music radio stations, in favor of streaming platforms. Curious about this phenomenon, we conducted an exploratory research in order to analyze how all these services, both traditional and new ones were perceived. Specifically, we aimed to study youth´s asse…
