11. Essays on Distance Based (Non-Euclidean) Tests for Spatial Clustering in Inhomogeneous Populations : Adjusting for the Inhomogeneity through the Distance Used
Abstract : This thesis consits of four papers dealing with distance based (non-Euclidean) tests for spatial clustering in inhomogeneous populations. The density adjusted distance (DAD), which considers the underlying density, is defined in the first paper. READ MORE

12. Efficient Approximate Big Data Clustering: Distributed and Parallel Algorithms in the Spectrum of IoT Architectures
Abstract : Clustering, the task of grouping together similar items, is a frequently used method for processing data, with numerous applications. Clustering the data generated by sensors in the Internet of Things, for instance, can be useful for monitoring and making control decisions. READ MORE

13. Progress in Hierarchical Clustering & Minimum Weight Triangulation
Abstract : In this thesis we study efficient computational methods for geometrical problems of practical importance and theoretical interest. The problems that we consider are primarily complete linkage clustering, minimum spanning trees, and approximating minimum weight triangulation. Below is a list of the main results proved in the thesis. READ MORE

14. Functional clustering methods and marital fertility modelling
Abstract : This thesis consists of two parts.The first part considers further development of a model used for marital fertility, the Coale-Trussell's fertility model, which is based on age-specific fertility rates. A new model is suggested using individual fertility data and a waiting time after pregnancies. READ MORE

15. Spatial clustering and industrial competitiveness : Studies in economic geography
Abstract : This thesis deals with the causes and effects of spatial clustering of similar and related economic activity. The relationship between spatial clustering and industrial competitive-ness is analysed in a series of empirical studies, revolving around four research questions: How useful is an institutional approach in analyses of spatial clustering? Can the link between spatial clustering and industrial performance be empirically validated and measured by quantitative methods? In what sense does spatial clustering promote localised processes of learning and innovation? What role can industrial and regional policies play in promoting the type of localised processes emphasised in spatial clustering research?It proves to be a rather complicated matter to measure the impact of spatial clustering on firm performance.
