  2. 1. Algorithmically Guided Information Visualization : Explorative Approaches for High Dimensional, Mixed and Categorical Data

    Author : Sara Johansson Fernstad; Mikael Jern; Jimmy Johansson; Jane Shaw; Matthew O. Ward; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Information visualization; data mining; high dimensional data; categorical data; mixed data;

    Abstract : Facilitated by the technological advances of the last decades, increasing amounts of complex data are being collected within fields such as biology, chemistry and social sciences. The major challenge today is not to gather data, but to extract useful information and gain insights from it. READ MORE

    Abstract : Water is essential for human well-being and healthy ecosystems, but population growth and changes in climate and land-use are putting increased stress on water resources in many regions. To ensure water security, knowledge about the spatiotemporal distribution of these resources is of great importance. READ MORE

  5. 3. From Numerical Sensor Data to Semantic Representations : A Data-driven Approach for Generating Linguistic Descriptions

    Author : Hadi Banaee; Amy Loutfi; Erik Schaffernicht; Andrey Kiselev; Mobyen Ahmed; Antonio Chella; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Semantic representations; Conceptual spaces; Natural language generation; Temporal rule mining; Physiological sensors; Health monitoring system;

    Abstract : In our daily lives, sensors recordings are becoming more and more ubiquitous. With the increased availability of data comes the increased need of systems that can represent the data in human interpretable concepts. READ MORE

  6. 4. Data Partitioning Methods and Parallel Block-Oriented PDE Solvers

    Author : Jarmo Rantakokko; Michael Thuné; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; data assimilation; data partitioning; meteorology; multiblock; Navier-Stokes; object-oriented; oceanography; parallel computing; Numerical Analysis; Numerisk analys;

    Abstract : Data partitioning methods for block-structured problems within scientific computing have been studied. The applications are variational data assimilation in meteorology, ocean modeling, and airflow simulation with multiblock grids. READ MORE

  7. 5. Efficient Modelling and Synthesis of Data Intensive Reconfigurable Systems

    Author : Per Andersson; Institutionen för datavetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; kontroll; Systems engineering; numerisk analys; system; control; Datalogi; numerical analysis; systems; Data Flow Graphs; Data Flow Modlling; computer technology; Data- och systemvetenskap; Computer science; Hardware Compilation; Synthesis;

    Abstract : Digital systems are integrated in our environment and have become a natural part of our every day life. As we rely more on these systems our expectations on them increases. We expect them to perform new tasks, communicate and cooperate. The complexity of these systems are increasing. READ MORE
