  1. 1. Image analysis to estimate the fractal dimension of soot aggregates

    Master-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Författare :Adrian Roth; [2018]
    Nyckelord :soot; aggregates; fractal; dimension; image; analysis; Technology and Engineering;

    Sammanfattning : Examensarbetet har utvecklat en metod för att estimera den fraktala dimensionen från Transmissions Elektron Mikroskop (TEM) bilder av sot aggregat som skapats med hjälp av en mini-CAST sotgenerator. Det är ett underbestämt problem att estimera den fraktala dimensionen, en 3D egenskap, från 2D bilder. LÄS MER

  3. 2. Case Studies on Fractal and Topological Analyses of Geographic Features Regarding Scale Issues

    Magister-uppsats, Högskolan i Gävle/Samhällsbyggnad, GIS

    Författare :Zheng Ren; [2017]
    Nyckelord :scale; fractal geometry; big data; topological analyses;

    Sammanfattning : Scale is an essential notion in geography and geographic information science (GIScience). However, the complex concepts of scale and traditional Euclidean geometric thinking have created tremendous confusion and uncertainty. LÄS MER

  4. 3. Fractal or Scaling Analysis of Natural Cities Extracted from Open Geographic Data Sources

    Magister-uppsats, Högskolan i Gävle/Avdelningen för Industriell utveckling, IT och Samhällsbyggnad

    Författare :KUAN-YU HUANG; [2015]
    Nyckelord :Open geographic data; box counting fractal dimension; head tail breaks classification; lacunarity; natural cities;

    Sammanfattning : A city consists of many elements such as humans, buildings, and roads. The complexity of cities is difficult to measure using Euclidean geometry. In this study, we use fractal geometry (scaling analysis) to measure the complexity of urban areas. We observe urban development from different perspectives using the bottom-up approach. LÄS MER

  5. 4. Fractal Geometry, Graph and Tree Constructions

    Master-uppsats, Institutionen för matematik och matematisk statistik

    Författare :Tommy Löfstedt; [2008]
    Nyckelord :;

    Sammanfattning : In the 18th and 19th centuries the branch of mathematics that would later be known as fractal geometry was developed. It was the ideas of Benoˆıt Mandelbrot that made the area expand so rapidly as it has done recently, and since the publication of his works there have for fractals, and most commonly the estimation of the fractal dimension, been found uses in the most diverse applications.
