Applying Axial Symmetries to Historical Silk Fabrics: SILKNOW’s Virtual Loom
2020
Symmetry is part of textile art in patterns and motifs that decorate fabrics, which are made by the interlacement of warp and wefts. Moreover, the 3D representation of fabrics have already been studied by some authors
视觉工作记忆存储的表征单位 [The Representation Unit of Visual Working Memory]
2022
The visual working memory is a limited storage system in which people could flexibly process the representations to complete the task. Among studies on the capacity of visual working memory, the representation unit is a prior subject. Previous research employs the change-detection paradigm and the recall paradigm to explore the nature of representations when features of diverse dimensions and different-level features of the same dimension are stored in the visual working memory. These studies elicit two binary hypotheses: the object-based representation hypothesis backs that those diverse features are bound on the object and form a whole, while the feature-based representation hypothesis su…
Relations between representational consistency, conceptual understanding of the force concept, and scientific reasoning
2012
Previous physics education research has raised the question of “hidden variables” behind students’ success in learning certain concepts. In the context of the force concept, it has been suggested that students’ reasoning ability is one such variable. Strong positive correlations between students’ preinstruction scores for reasoning ability (measured by Lawson’s Classroom Test of Scientific Reasoning) and their learning of forces [measured by the Force Concept Inventory (FCI)] have been reported in high school and university introductory courses. However, there is no published research concerning the relation between students’ ability to interpret multiple representations consistently (i.e.,…
Does using a visual-representation tool foster students’ ability to identify forces and construct free-body diagrams?
2013
Earlier research has shown that after physics instruction, many students have difficulties with the force concept, and with constructing free-body diagrams (FBDs). It has been suggested that treating forces as interactions could help students to identify forces as well as to construct the correct FBDs. While there is evidence that identifying interactions helps students in quantitative problem solving, there is no previous research investigating the effect of a visual-representation tool—an interaction diagram (ID)—on students’ ability to identify forces, and to construct the correct FBDs.We present an empirical study conducted in 11 Finnish high schools on students (n ¼ 335, aged 16) takin…

Modelling and analysing oriented fibrous structures
2014
Abstract. A mathematical model for fibrous structures using a direction dependent scaling law is presented. The orientation of fibrous nets (e.g. paper) is analysed with a method based on the curvelet transform. The curvelet-based orientation analysis has been tested successfully on real data from paper samples: the major directions of fibrefibre orientation can apparently be recovered. Similar results are achieved in tests on data simulated by the new model, allowing a comparison with ground truth. peerReviewed
Representations of the Life-giving Spring feast in Romanian iconography
2021
This article explores the development of the theme of the Life-giving Spring in Byzantine iconography. The path towards its establishment was initiated at the moment when a representation rule, an original convention was set. Thereafter, because of its diffusion in time and space, the theme became enriched by particular mentalities and sensibilities of the epochs and the communities that adopted it as a form of devotion for the Virgin Theotokos. As a result, the representations we have known so far are extremely varied. Contribution: The final purpose of this approach, as well as its contribution, is to highlight the diverse unity of the iconographic tradition and illustrate both the evolut…
Yleisön mediarepresentaatiot Ilta-Sanomien ja Urheilulehden vuoden 2011 miesten jääkiekon MM-kisauutisoinnissa
2017
Tutkimuksessa tarkastellaan Ilta-Sanomien ja Urheilulehden vuoden 2011 miesten jääkiekon MM-kisauutisoinnissa tuotettuja yleisörepresentaatioita. Tutkimustehtävänä on eritellä urheiluyleisölle lehtijutuissa tuotettuja toimija-asemia ja tulkita niihin liittyviä merkityksiä. Jutuissa käsiteltäviä yleisöjä ovat niin tapahtumissa paikanpäällä olevat fanijoukot kuin vastaanottimien välityksellä tapahtumia seuraavat. Tutkimuksen kokonaisaineisto koostuu 20.4.–31.5.2011 ilmestyneistä Ilta-Sanomien (34) ja Urheilulehden (5) numeroista. Laadullisen analyysin kohteeksi valittiin kaikki ne jutut, jotka sisälsivät sanallista yleisön representointia. Tällaisia juttuja julkaistiin Ilta-Sanomissa 94 ja Ur…
Exploring the collaborative synthesis of information during online reading
2019
Abstract This descriptive study sought to understand the complexities of integrative processing during collaborative online reading. Student pairs constructed a collaborative understanding while reading online information about a controversial issue by connecting, combining and organizing information that originated from prior knowledge, self-selected online texts, and discussions during an online inquiry task. Thirty-eight students from an upper secondary school in Finland worked in pairs to read online information and write an essay with the help of an argument graph tool. Primary data sources consisted of: prior knowledge; discussions; notes recorded with a graphic representational tool;…
Miten konesydän sykkii? Ruotsalainen Hubotit – melkein ihmisiä ei pelkää kysyä isoja kysymyksiä.
2013
Hubotit - melkein ihmisiä (Äkta Människor, Ruotsi 2011-) tuo pohjoismaiseen televisiofiktioon tieteisfiktion tutut teemat kuten ihmisen ja koneen risteymät sekä kuolemattomuuden. Teknologisen kehityksen takana tieteisfiktiossa piilee usein, ellei jopa aina, kysymyksiä kehityksen vaikutuksesta ihmisyyteen. Myös Hubotit - melkein ihmisiä esittää näitä suuria kysymyksiä: Mitä meille tapahtuu teknologian kehittyessä? Voimmeko muuttua joksikin paremmaksi teknologian avulla, vai onko ihmisyys jotain, jota ei voi teknologian avulla luoda tai laajentaa? Millainen voisi olla ihmismielen, -sydämen ja -sielun ohjelmakoodi? nonPeerReviewed
