1. A GIS-Based Method of Deriving Spatially Distributed Unit Hydrographs
University essay from KTH/Hållbar utveckling, miljövetenskap och teknikAbstract : Prior to using hydraulic and spatially distributed modelling softwares, the theory of the unit hydrograph was a commonly used tool for modelling of surface and runoff water. While distributed models often provide detailed results from extensive calculation durations, the unit hydrograph have been questioned for simplifying the physical characteristics of the watershed modelled.

2. Focal Operations with Network Distance Based Neighbourhoods : Implementation, Application and Visualization
University essay from KTH/GeoinformatikAbstract : In spatial analysis, many operations are performed considering the neighbouring locations of a feature. The standard definition of a neighbourhood is an area confined by geometrical length and direction with respect to its focus. When allocating a location for a service, the population distribution is often considered. READ MORE

3. Properties of a generalized Arnold’s discrete cat map
University essay from Linnéuniversitetet/Institutionen för matematik (MA)Abstract : After reviewing some properties of the two dimensional hyperbolic toral automorphism called Arnold's discrete cat map, including its generalizations with matrices having positive unit determinant, this thesis contains a definition of a novel cat map where the elements of the matrix are found in the sequence of Pell numbers. This mapping is therefore denoted as Pell's cat map. READ MORE
