Problem Transformation Methods with Distance-Based Learning for Multi-Target Regression

2020

Multi-target regression is a special subset of supervised machine learning problems. Problem transformation methods are used in the field to improve the performance of basic methods. The purpose of this article is to test the use of recently popularized distance-based methods, the minimal learning machine (MLM) and the extreme minimal learning machine (EMLM), in problem transformation. The main advantage of the full data variants of these methods is the lack of any meta-parameter. The experimental results for the MLM and EMLM show promising potential, emphasizing the utility of the problem transformation especially with the EMLM. peerReviewed

Il primo concorso per il Palazzo di Giustizia a Roma del 1884. Ricostruzione critica del progetto di Ernesto Basile

2019

1. Breve descrizione dell’oggetto di studio Il concorso del Palazzo di Giustizia di Roma si svolge in quattro fasi svolte tra il 1884 e il 1887. Il progetto per il primo concorso, del 1884, redatto dall’allora giovanissimo Ernesto Basile (Palermo 1857-1932), rivela una grande perizia progettuale che trasforma il complesso programma funzionale in un austero edificio in stile neofiorentino. I disegni originari dell’opera, non realizzata, conservati presso la Dotazione Basile del Dipartimento di Architettura dell’Università di Palermo, sono stati oggetto di studio propedeutico alle fasi di analisi, interpretazione e ricostruzione congetturale del modello digitale. 2.

Objectives pursued and achieved Conjectural reconstruction achieved the following results: • formulation of analytical documents which show how the planimetric and altimetric articulation are perfectly consistent with the functional program• definition of the level of uncertainty1. Brief description of the object of study The competition of the Palace of Justice in Rome takes place in four phases between 1884 and 1887. The project for the first competition in 1884 drawn up by the then very young Ernesto Basile (Palermo 1857-1932) reveals a great deal of design expertise that transforms the complex functional program into an austere building in neo-florentine style. The original drawings of the building not realized kept in the Basile Endowment of the Department of Architecture of the University of Palermo have been the subject of preliminary study to the phases of analysis interpretation and conceptual reconstruction of the digital model. 2. State of the art and main bibliographical references The conjectural reconstruction on the basis of drawings and archival documents is a well-established and codified practice thanks to various disciplinary contributions at national and international level.

Evaluation of web reinforcements in prestressed concrete box girders through shear-transverse bending domains

2020

In concrete box girders, the amount and distribution of reinforcements in the webs have to be estimated considering the local effects due to eccentric external loads and cross-sectional distortion and not only the global effect due to the resultant forces of a longitudinal analysis: shear, torsion and bending. This work presents an analytical model that allows designers to take into account the interaction of all these effects, global and local, for the determination of the reinforcements. The model is based on the theory of stress fields and it has been compared to a 3D finite element analysis, in order to validate the interaction domains. The results show how the proposed analytical mode…

De-naturalizing the “predatory”: A study of “bogus” publications at public sector universities in Pakistan

2022

Predatory publishing has recently emerged as a menace in academia. University professors and researchers often exploit this practice for their economic gains and institutional prestige. The present study investigates such existing predatory publishing practices in Pakistani public sector universities using Bourdieu’s (1991) concept of symbolic violence. For this purpose, we analyzed 495 articles published by 50 university professors in the social sciences and humanities over the period 2017-2021. We also conducted semi-structured interviews with 20 postgraduate students to gather their perspectives on publishing practices. The study shows that 69% of the sample papers were published in pred…

Nekustamā īpašuma tirgus tiesiskā regulējuma realitāte un tiesību efektivitāte (2006-2016.g)

2018

Ņemot vērā, ka 1995.gada un 2007.gada krīzes ievērojami nobremzēja nekustamā īpašuma tirgus veidošanas procesu Latvijā, šodien ir vērojams aktivitātes pieaugums visās nekustamā īpašuma tirgus jomās, kaut gan par pilnīgi sakārtotu nekustamā īpašuma tirgu runāt vēl pāragri. Tieši tāpēc darbam ir liela nozīmē tālākai nekustamā īpašuma tirgus attīstībai. Tajā tie aplūkota nekustamā īpašuma tirgus situācija sākot ar pirmskrīzes periodu un izanalizēti vissaktuālākie jautājumi, par kuriem pēdējo gadu laikā spriež visi nekustamo īpašumu tirgus speciālisti. Pirmā darba nodaļa ir vispārēja nodaļa, kurā informācija tiek sniegta, lai sagatavotu lasītāju turpmākajām tēmām un iepazīstināt ar galvenajiem …

Mathematical thinking and understanding in learning of mathematics

2022

The concept “mathematical thinking” can be found in several studies of mathematics education, in national curricula or in media during the decades all over the world. We searched words “mathematical thinking” from the database of international scientific articles, and we found 456 707 mentions at first time. These are the main reasons why we have chosen “mathematical thinking” as the central concept of the Special Issue. The other interesting question from our point of view is how a student can express his/her mathematical thinking? By answering this question, we have made simple model for the teacher education purposes, and we call it “languaging” (of mathematical thinking). The articles o…

Läpinäkyvyys kunnan toiminnassa - tietopyyntöihin vastaaminen

2016

Tietopyyntöongelmien ratkaiseminen kunnallishallinnossa on Kunnallisalan kehittämissäätiön (KAKS) rahoittama hanke, joka toteutettin Jyväskylän yliopiston Viestintätieteiden laitoksessa vuosina 2015 - 2016. Hankkeessa selvitettiin kuntien ongelmia vastata julkisuuslain mukaisiin tietopyyntöihin. Osana hanketta tutkijat tekivät tietopyynnön sähköpostilla jokaiseen Manner-Suomen kuntaan (301 kpl) touko-kesäkuussa 2015. Tähän Excel-taulukkoon on koottu näistä pyynnöistä seuraavia tietoja: - Kunta - Sähköpostiosoite, johon pyyntö lähetettiin - Lähetyspäivämäärä - Viestin kuittauspäivämäärä - Oliko ensimmäinen yhteydenotto puhelinsoitto - Päiviä vastaukseen lähetyksestä - Päiviä tietojenluovutuk…
