  1. 1. Complexity Theory and Physics Education Research : The Case of Student Retention in Physics and Related Degree Programmes

    Författare :Jonas Forsman; Cedric Linder; Ismo Koponen; Uppsala universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; SOCIAL SCIENCES; Physics Education Research; Complexity Theory; Student Retention; Physics with specialization in Physics Education; Fysik med inriktning mot fysikens didaktik;

    Sammanfattning : This thesis explores the use of complexity theory in Physics Education Research as a way to examine the issue of student retention (a university’s ability to retain its students). University physics education is viewed through the concepts of nestedness and networked interactions. LÄS MER

    Sammanfattning : We are constantly struggling to understand how nature works, trying to identify recurrent events and looking for analogies and relations between objects or individuals. Knowing patterns of behavior is powerful and fundamental for survival of any species. LÄS MER

  3. 3. Depletion and decline curve analysis in crude oil production

    Författare :Mikael Höök; Kjell Aleklett; Roger Bentley; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; depletion rate; decline curve analysis; crude oil production; Other earth sciences; Övrig geovetenskap; Mathematical physics; Matematisk fysik; Other engineering physics; Övrig teknisk fysik; Physics with specialization in Global Energy Resources; Fysik med inriktning mot globala energiresurser;

    Sammanfattning : Oil is the black blood that runs through the veins of the modern global energy system. While being the dominant source of energy, oil has also brought wealth and power to the western world. Future supply for oil is unsure or even expected to decrease due to limitations imposed by peak oil. Energy is fundamental to all parts of society. LÄS MER
