  2. 1. Data mining of geospatial data: combining visual and automatic methods

    Author : Urška Demšar; Hans Hauska; Peter A. Burrough; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; geographic information science; geoinformatics; geovisualisation; spatial data mining; visual data mining; usability evaluation; Other information technology; Övrig informationsteknik;

    Abstract : Most of the largest databases currently available have a strong geospatial component and contain potentially useful information which might be of value. The discipline concerned with extracting this information and knowledge is data mining. Knowledge discovery is performed by applying automatic algorithms which recognise patterns in the data.

  4. 2. Mapping incomplete relational data : networks in ecology & evolution

    Author : Daniel Edler; Martin Rosvall; Alexandre Antonelli; Renaud Lambiotte; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; network science; information theory; map equation; community detection; biogeography; evolution;

    Abstract : We live in an interconnected world full of complex systems that cannot be understood simply by analyzing their components. From how genes regulate biological functions to the distribution of life on Earth, we need methods that can analyze systems as a whole. READ MORE

  5. 3. Hierarchical Concurrent Systems from a Model-Oriented perspective

    Author : Daniel Einarson; Data Vetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; control; systems; numerical analysis; Computer science; Distributed Systems; Hierarchical Systems; Object-Orientation; Model-Orientation; Datalogi; numerisk analys; system; kontroll; Systems engineering; computer technology; Data- och systemvetenskap;

    Abstract : Real world systems are normally considered as hierarchically organized, for example, we see those as hierarchies of systems including subsystems. Examples on this can be seen in organizations where people act in environments and carry within themselves their own internal subsystem of thinking processes. READ MORE

  6. 4. Progress in Hierarchical Clustering & Minimum Weight Triangulation

    Author : Drago Krznaric; Institutionen för datavetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; computer technology; Systems engineering; minimum spanning tree; complete linkage; hierarchical clustering; minimum weight triangulation; greedy triangulation; Data- och systemvetenskap;

    Abstract : In this thesis we study efficient computational methods for geometrical problems of practical importance and theoretical interest. The problems that we consider are primarily complete linkage clustering, minimum spanning trees, and approximating minimum weight triangulation. Below is a list of the main results proved in the thesis. READ MORE

  7. 5. Hierarchical Control and Restart of Flexible Manufacturing Systems

    Author : Kristin Andersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Restart; Flexible manufacturing; Finite state automata; Petri nets; Supervisory control theory; Process algebra; Discrete event systems; Hierarchical control; Supervisor synthesis;

    Abstract : Product life-cycles are constantly shortening, and the amount of new product types increases, for example in the automotive industry. Growing demands on flexibility and ability to decrease time to market has made it increasingly important to find methods for fast and accurate development of control programs for flexible manufacturing cells.
