Abstract:
The study of patterns in combinatorial structures has grown up in the past few decades to one of the most active trends of research in combinatorics. Historically, the study of permutations which are constrained by not containing subsequences ordered in various prescribed ways has been motivated by the problem of sorting permutations with certain devices. However, the richness of this notion became especially evident from its plentiful appearances in several very different disciplines, such as pure mathematics, mathematical physics, computer science, biology, and many others.

Abstract:
In this dissertation we first study partition posets and their topology. For each composition c we show that the order complex of the poset of pointed set partitions is a wedge of spheres of the same dimension with the multiplicity given by the number of permutations with descent composition c. Furthermore, the action of the symmetric group on the top homology is isomorphic to the Specht module of a border strip associated to the composition. We also study the filter of pointed set partitions generated by knapsack integer partitions. In the second half of this dissertation we study descent avo

Abstract:
The rigorous development, application and validation of distributed hydrological models obligates to evaluate data in a spatially distributed way. In particular, spatial model predictions such as the distribution of soil moisture, runoff generating areas or nutrient-contributing areas or erosion rates, are to be assessed against spatially distributed observations. Also model inputs, such as the distribution of modelling units derived by GIS and remote sensing analyses, should be evaluated against groundbased observations of landscape characteristics. So far, however, quantitative methods of sp

Thesis (MEng)--Stellenbosch University, 2014.<br>ENGLISH ABSTRACT: The fairly recent introduction of low-cost depth sensors such as Microsoft’s Xbox Kinect has encouraged a large amount of research on the use of depth sensors for many common Computer Vision problems. Depth images are advantageous over normal colour images because of how easily objects in a scene can be segregated in real-time. Microsoft used the depth images from the Kinect to successfully separate multiple users and track various larger body joints, but has difficulty tracking smaller joints such as those of the fingers

In addition to the influence of Chinese and European cultures, those of other Eastern countries were also included. Because of the introduction of Japanese style and the autarky of China, the trend of Chinese style started to fade in the middle of the 19th century.

Abstract:
The visual reconstruction problems have often an ill-posed nature. In this thesis we deal with analyzing and solving three kinds of visual reconstruction problems: Blind Source Separation, Demosaicing and Deblurring. The demosaicing problem is related to the acquisition of RGB color images by means of CCD digital cameras. In the RGB model, each pixel of a digital color image is associated to a triple of numbers, which indicate the light intensity of the red, green and blue channel, respectively. However, most cameras use a single sensor, associated with a color filter that allows only th
