  1. 1. Schema Integration How to Integrate Static and Dynamic Database Schemata

    Detta är en avhandling från Karlstad : Karlstads universitet

    Författare :Peter Bellström; Karlstads universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Schema Integration; Conceptual Database Design; Database Schemata; Enterprise Modeling; Information Systems; Informatik;

    Sammanfattning : Schema integration is the task of integrating several local schemata into one global database schema. It is a complex, error-prone and time consuming task. Problems arise in recognizing and resolving problems, such as differences and similarities, between two schemata. Problems also arise in integrating static and dynamic schemata. LÄS MER

  2. 2. Integration of Biological Data

    Detta är en avhandling från Institutionen för datavetenskap

    Författare :Vaida Jakonienė; Patrick Lambrix; Nahid Shahmehri; Michael Schroeder; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datalogi; integration; grouping; databases; ontologies; biological data; ioinformatics; KitEGA; Datalogi; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Data integration is an important procedure underlying many research tasks in the life sciences, as often multiple data sources have to be accessed to collect the relevant data. The data sources vary in content, data format, and access methods, which often vastly complicates the data retrieval process. LÄS MER

    Sammanfattning : This thesis presents methods for the wafer-level integration of shape memory alloy (SMA) and electrostatic actuators to functionalize MEMS devices. The integration methods are based on heterogeneous integration, which is the integration of different materials and technologies. LÄS MER

  5. 5. Radiation Oncology Data and Modelling Side Effects after Radiation Therapy

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Caroline Olsson; Göteborgs universitet.; Gothenburg University.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dose and side effect data; dose-volume response; fractionation effect; LQ model; sequential two-phase radiotherapy; head and neck cancer; parotid gland; xerostomia; pelvic radiotherapy; gynecological cancer; pubic bone; pain; data integration;

    Sammanfattning : Although modern radiation therapy techniques have the ability to conform the dose distribution of ionizing radiation tightly around the volume to be treated, unwanted irradiation to surrounding organs remains a problem. The probability of a side effect arising in the normal tissue of a patient after radiation therapy can be modelled by sigmoid mathematical functions known as normal tissue complication probability (NTCP) models.
