  1. 1. Cluster Initiatives as Intermediaries : A Study of their Management and Stakeholders

    Författare :Inessa Laur; Magnus Klofsten; Dzamila Bienkowska; Peter Van der Sijde; Linköpings universitet; []
    Nyckelord :Cluster; cluster initiatives; intermediary organization; regional development; entrepreneurship; success factors; actors stakeholders and activities;

    Sammanfattning : This dissertation offers a platform to understand the nature of cluster initiatives as a socio-economic phenomenon combining cluster, entrepreneurship and intermediary features. They are particular types of ventures facilitating networks and dialog platforms adjusted to local contexts and offering a way to enhance regional development. LÄS MER

  3. 2. Bayesian Cluster Analysis : Some Extensions to Non-standard Situations

    Författare :Jessica Franzén; Daniel Thorburn; Jukka Corander; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Cluster analysis; Clustering; Classification; Mixture model; Gaussian; Bayesian inference; MCMC; Gibbs sampler; Deviant group; Longitudinal; Missing data; Multiple imputation; Statistics; Statistik; Statistics; statistik;

    Sammanfattning : The Bayesian approach to cluster analysis is presented. We assume that all data stem from a finite mixture model, where each component corresponds to one cluster and is given by a multivariate normal distribution with unknown mean and variance. LÄS MER

  4. 3. Kunskap och innovation i ett moget kluster : En ekonomisk-geografisk studie av aluminiumindustrin i Småland-Blekinge

    Författare :Magnus Lagerholm; Anders Malmberg; Anders Waxell; Karl-Johan Lundquist; Uppsala universitet; []
    Nyckelord :Social and economic geography; economic geography; mature industry; cluster; agglomeration; systems of innovation; labour market mobility; Sweden; Kulturgeografi; kulturgeografi; Social and Economic Geography;

    Sammanfattning : The thesis aims at understanding mechanisms behind knowledge generation and learning in a mature cluster by analysing firms in south-east Sweden engaged in the development and manufacturing of aluminium products. The point of departure is in concepts and assumptions related to spatially concen-trated systems of similar and related firms and industries, such as agglomera-tions, clusters or innovation systems.

  5. 4. Simulations of water clustering in vapour, hydrocarbons and polymers

    Författare :Erik Johansson; Högskolan i Borås; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; cluster; gibbs ensemble; monte carlo; water; polyethylene; external field; ions; Energi och material; Water; Monte Carlo; Gibbs Ensemble; Ion; External field; Cluster; Polyethylene;

    Sammanfattning : It is commonly known that water plays a crucial role in many natural and industrial processes. One of these processes is the formation of water trees, and the subsequent breakdown of polyethylene used for high voltage cable insulation purposes. LÄS MER

  7. 5. Metal Cluster Reactivity. Adsorption of small molecules in biomolecular collisions

    Författare :Mats Andersson; Chalmers University of Technology; []
    Nyckelord :O2; CO; ionization potential; Con; Fen; NO; sticking probability; laser ionization; D2; Wn; Cun; Rhn; reaction probability; cluster; jellium model; Nbn; metal cluster reactivity; N2; time-of-flight mass spectrometry; Nin;

    Sammanfattning : Metal clusters can be characterized as the tiniest possible metal particles, containing only an easily counted number of atoms. In this work, reactions between metal clusters and diatomic molecules have been investigated. We have constructed an experimental set-up to produce and detect clusters, and to investigate their chemical reactivity. LÄS MER
