    Sammanfattning : In many fields of science, engineering, and economics large amounts of data are stored and there is a need to analyze these data in order to extract information for various purposes. Data mining is a general concept involving different tools for performing this kind of analysis. LÄS MER

  2. 2. Minimal volume ventilation in lung injury With special reference to apnea and buffer treatment

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Staffan Höstman; Uppsala universitet.; [2016]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; VILI; THAM; buffers; apneic oxygenation; respiratory acidosis; hypercapnia; low volume ventilation; mechanical ventilation; ultra-protective ventilation; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Sammanfattning : A fairly large portion of patients receiving surgical or intensive care will need mechanical ventilation at some point. The potential ventilator-induced lung injury (VILI) is thus of interest. One of the main causal factors in VILI is the cyclic energy shifts, i.e. LÄS MER

  3. 3. Low Voltage CMOS Radio Receiver Front-End Design

    Detta är en avhandling från Department of Electroscience, Lund University

    Författare :Fred Tillman; Lunds universitet.; Lund University.; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; Electrical engineering; Elektronik; Electronics; Elektronik och elektroteknik; Electronics and Electrical technology; Polyphase Filter; Quadrature Signals; Nonlinearity; Distortion; Passive Mixer; Mixer; Low Noise Amplifier; CMOS; Front-End; Low Voltage; Radio; Receiver;

    Sammanfattning : The mass production of integrated circuits for digital electronics has made CMOS technology the most frequently used IC process today. Thanks to the large production volume, CMOS has increasingly become the most cost efficient technology of choice, and the fast development of small, high speed CMOS devices has made the technology feasible for many RF applications.

  4. 4. Timber volume element prefabrication production and market aspects

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Matilda Höök; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Sammanfattning : Problems discussed within the Swedish housing industry are lack of competition, quality and increased costs. Improvements to cope with these problems have shown to be low compared to manufacturing and other industries. LÄS MER

  5. 5. Free Volume Depth Profiling at Polymer Surfaces and Interfaces

    Detta är en avhandling från Birgitta Ryd, Polymer Science & Engineering, Center for Chemistry and Chemical Engineering, Lund

    Författare :John Algers; Lunds universitet.; Lund University.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biopolymers; Polymerteknik; Polymer technology; polymer interfaces; polymer surfaces; positron lifetime; free volume;

    Sammanfattning : Pulsed low energy positron beams provide a unique and non-destructive tool to depth probe the free volume of polymers at surfaces and interfaces. Since the employment of low energy positron beams in polymer research is an emerging technique, some focus in this thesis has been on extracting methods and equations needed to interpret the experimental data.
