Most real objects have nonlinear characteristics, so mathematical expression of an inverse model cannot be obtained in most situation. A Takagi–Sugeno(T-S)fuzzy model can approximate real objects with high precision, and is often applied in the modeling of nonlinear systems. Since the consequent parameters of T-S fuzzy models are linear expressions, this paper firstly uses a fuzzy c-regression model (FCRM) clustering algorithm to establish inverse fuzzy model. As the least mean square (LMS) algorithm is only used to adjust consequent parameters of the T-S fuzzy model in the process of parameter adjustment, the premise parameters are fixed and unchanged in the process of adjustment. In this paper, the back propagation (BP) algorithm is applied to adjust the premise and consequent parameters of the T-S fuzzy model, simultaneously online. The simulation results show that the error between the system output controlled by proposed adaptive inverse controller and the desired output is smaller, also the system stability can be maintained when the system output has disturbances.","PeriodicalId":50362,"journal":{"name":"Information-An International Interdisciplinary Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74418820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Innen dette programmet er det utviklet en metode basert på estetiske prosessorienterte tilnærmingsmåter der møtet med et kunstverk starter en aktiv prosess hos betrakteren. «Inn i bildet» viser hvordan kunstbasert læring kan fungere som verktøy for trening av refleksjonsevnen, noe som igjen kan gi forståelse og innsikt både individuelt og som gruppe. Metoden er spesielt egnet for områdene utdanning, arbeidsliv og psykisk helse. Denne artikkelen er en analyse av hvordan arbeidet med et fritt valgt kunstverk bearbeides videre i eget personlig uttrykk. Deltagerne eksperimenterer med ulike teknikker i atelieret, veiledet av kunstpedagoger / Teaching Artist (TA). TA er en profesjonell kunstner som arbeider med kunst i utdanning eller i tilknytning til samfunnsorganisasjoner, i denne sammenheng ved Nasjonalmuseet.

The article discusses cultural participation for, with and by children based on the core ideas of a Swedish governmentally initiated strategy implemented in the 1970s. The right for children to take part in cultural activities, to be culturally active and to express themselves is based on the UN Convention on the Rights of the Child (1989). Art education and visual activities for children in formal and informal cultural environments and the use of contemporary art will be discussed. An art-based project in collaboration between a cultural institution and preschool and younger children is described. The main purpose of the article is to analyse what impact the use of cultural participation and cultural tools has on children's collective experience and learning, as well as to discuss and contextualise the relationship between culture, preschool and school as it is influenced by global and societal changes, particularly the increasing visual impact in society through the use of digital media and multimodality. The results show how an art gallery visit and the use of cultural narratives, such as art educational activities at a preschool based on work with a picture book, create visual knowledge and contribute to children’s agency and understanding of equity as one of the aims in the early childhood education curriculum.","PeriodicalId":50362,"journal":{"name":"Information-An International Interdisciplinary Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83678395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research is conducted in two institutions, both of which are dedicated facilities for the care of elderly dementia sufferers. The project examines how narrative and poetic documentation influences didactic choices in a process-oriented practice. The study interprets the term ‘art-practice’ as being a catalyst for communication between the artist, the patient and the caregiver. The term ‘poetic documentation’ is a central didactic component which enables applied art qualities such as affective encounters through different material; the integration of lived experience and the participants’ life possibilities to be understood from a unified perspective. The strategies for documenting the artistic process will examine ethical issues concerning the obtaining of consent from participants with a reduced intellectual capacity. The methods applied in the research process are arts-informed enquiry and practice-led research using visual methods. The article argues for the development of more comprehensive theoretical perspectives on the problems encountered. Strategies developed in the course of the study will be communicated through workshops for healthcare workers and students, which will focus on the need for cooperation between the healthcare institutions involved, the researcher and the artist.","PeriodicalId":50362,"journal":{"name":"Information-An International Interdisciplinary Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90905635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cryptographic primitives mandate a non-linear operation. The design of a lightweight, secure, non-linear 4 × 4 substitution box (S-box) suited to Internet of Things (IoT) applications is proposed in this work. The structure of the 4 × 4 S-box is devised in the finite fields GF (24) and GF ((22)2). The finite field S-box is realized by multiplicative inversion followed by an affine transformation. The multiplicative inverse architecture employs Euclidean algorithm for inversion in the composite field GF ((22)2). The affine transformation is carried out in the field GF (24). The isomorphic mapping between the fields GF (24) and GF ((22)2) is based on the primitive element in the higher order field GF (24). The recommended finite field S-box architecture is combinational and enables sub-pipelining. The linear and differential cryptanalysis validates that the proposed S-box is within the maximal security bound. It is observed that there is 86.5% lesser gate count for the realization of sub field operations in the composite field GF ((22)2) compared to the GF (24) field. In the PRESENT lightweight cipher structure with the basic loop architecture, the proposed S-box demonstrates 5% reduction in the gate equivalent area over the look-up-table-based S-box with TSMC 180 nm technology.","PeriodicalId":50362,"journal":{"name":"Information-An International Interdisciplinary Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74805351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Children’s music is a broad term and may include music produced by adults for children (culture for children), music and musical practices that children and adults engage in together (culture with children), and the music children themselves make and how they engage with it in their own networks and relations (culture by children) (see Mouritsen, 2002, for a discussion of children’s culture in general). The three threads of the definition of children’s culture and, thus, of children’s music, are arguably closely connected. For instance, consider a young child listening to a pop song for children on an iPad while walking rhythmically around the room and singing along to the music. This imagined scene involves music produced for a child audience. Moreover, the scene is taking place in a social setting in which adults have provided the child with a technological device that enables the child to listen to music. This means that both parties—child and adult—contribute to this scene of contemporary musical children’s culture. Hence, one can describe the situation as culture with children. Finally, if the child’s musical engagement is focused (moving and singing along with the music), the scene may be described as music by children.","PeriodicalId":50362,"journal":{"name":"Information-An International Interdisciplinary Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83016913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
