The Dade group of a fusion system.
No full textWe define the notion of the Dade group of a fusion system and show that some of the gluing and detection results for Dade groups of finite p-groups due to Bouc and Thévenaz in [S. Bouc and J. Thévenaz. Gluing torsion endo-permutation modules. (Preprint.)], [S. Bouc and J. Thévenaz. A sectional characterization of the Dade group. J. Group Theory 11 (2008), 155–183.] extend to Dade groups of fusion systems

Collaborative Authoring of Adaptive Educational Hypermedia by Enriching a Semantic Wiki’s Output
No full textThis research is concerned with harnessing collaborative approaches for the authoring of Adaptive Educational Hypermedia (AEH) systems. It involves the enhancement of Semantic Wikis with pedagogy aware features to this end. There are many challenges in understanding how communities of interest can efficiently collaborate for learning content authoring, in introducing pedagogy to the developed knowledge models and in specifying user models for efficient delivery of AEH systems. The contribution of this work will be the development of a model of collaborative authoring which includes domain specification, content elicitation, and definition of pedagogic approach. The proposed model will be implemented in a prototype AEH authoring system that will be tested and evaluated in a formal education context
Verification of the McKay-Alperin-Dade Conjecture for the covering groups of the Mathieu group M(22)
No full textThe McKay-Alperin-Dade Conjecture states that the number of complex irreducible characters with a given defect d in a p-block B of a finite group G can be expressed in terms of an alternating sum of the numbers of complex irreducible characters with related defects d\sp\prime in related p-blocks B\sp\prime of the normalizers N\sb{G}(C) of representatives C of the G-conjugacy classes of radical p-chains of G. Specifically, we have the following.Conjecture A (The McKay-Alperin-Dade conjecture). If O\sb{p}(G) is the Sylow p-subgroup of a central subgroup N of G, and is not a defect group of B then \sum\limits\sb{C\in{\cal R}/G}(-1)\sp{\vert C\vert}k(N\sb{G}(C),B,d,O\vert\nu) = 0for any where is a linear character of N and is our family of representatives.This paper presents a verification of the M-A-D Conjecture for the group 12.M\sb{22}, whose order is 2\sp9\cdot3\sp3\cdot5\cdot7\cdot11. Since Dade has shown that Conjecture A holds for any blocks with cyclic defect groups, this paper deals specifically with the primes 3 and 2. In each case, representatives of the M\sb{22}-conjugacy classes of the radical p-subgroups of M\sb{22} are identified, together with their normalizers. Subsequently, a complete listing of the representatives of the M\sb{22}-conjugacy classes of radical p-chains C, together with their normalizers N\sb{M\sb{22}}(C) is made.The normalizers N\sb{n.M\sb{22}}(C) are then determined for each radical p-chain C and for n = 1,2,3,4,6,12. The action of the outer automorphism group of M\sb{22}, which is cyclic of order 2, on each of the groups N\sb{n.M\sb{22}}(C) is identified. Finally, the M-A-D Conjecture is verified for the 3-blocks and the 2-blocks of n.M\sb{22}.Made available in DSpace on 2011-05-07T12:14:28Z (GMT). No. of bitstreams: 2

A aplicação da metodologia de produção mais limpa através do círculo de controle da qualidade - CCQ em uma indústria do setor metal mecânico: estudo de caso
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós-graduação em Engenharia de Produção, Florianópolis, 2002O presente trabalho consiste em uma aplicação da metodologia de produção Mais Limpa P+L, através dos grupos de melhorias baseados nos Círculos de Controle de Qualidade CCQ. A metodologia de P+L foi desenvolvida pela UNEP e a UNIDO que são as instituições das Nações Unidas para o meio ambiente e desenvolvimento industrial, a partir de um conceito criado pela ONG Greenpeace chamada Produção Limpa. Esta metodologia baseia-se em uma abordagem preventiva, integrada e contínua aplicada aos processos produtivos, permitindo aumentar a eficiência no uso de matérias primas, insumos, água e energia, diminuindo assim os riscos para o homem e o meio ambiente. Para a consecução destes objetivos aplicou-se a metodologia de P+L em uma empresa do setor metalúrgico, de forma descentralizada, utilizando vários grupos de CCQ existentes na organização e promovendo uma interface entre o sistema de gestão qualidade implantado e a gestão das questões ambientais. Este tema foi escolhido em função dos conflitos que geralmente ocorrem através da percepção equivocada que existe uma concorrência entre os trabalhos efetuados no âmbito da P+L e aqueles feitos nos grupos de CCQ. Os resultados alcançados no trabalho evidenciaram a viabilidade da aplicação da metodologia de P+L através dos grupos de melhoria baseados nos CCQ, bem como conduziram a conclusão de que esta formatação proposta pode ser uma alternativa para as atividades de P+L em grandes empresas, por facilitar a permeabilidade do conceito através dos diversos níveis estruturais da organização, bem como no envolvimento de maior numero de profissionais envolvidos ativamente na busca de tecnologias que possibilitem uma produção mais limpa e mais eficiente economicamente
Improving the workspace awareness of authors in asynchronous collaborative authoring of learning designs
No full textCreating adaptive learning resources is a complex, time-consuming process. Problems emerged regarding interoperability, reusability, and collaboration. This paper discusses a collaborative authoring approach to develop adaptive learning resources. The contribution of this paper is twofold. The first contribution is the analysis of the most suitable learning standard for representing adaptive learning resources and to be used for collaborative authoring. It is gained from an analysis and experiments through designing some small cases in various learning standards. The second contribution is the analysis of the implication of two collaborative features: Notes in which authors can leave comments and History which records provenance information. It is gained from a Between-group experiment. One finding shows that IMS Learning Design (IMS LD) has more advantages than other learning standards. Another finding shows that Note and History have positive implications for collaborative authoring of adaptive learning resources represented in IMS LD
