While the maturity of process mining algorithms increases and more process mining tools enter the market, process mining projects still face the problem of different levels of abstraction when comparing events with modeled business activities. Current approaches for event log abstraction try to abstract from the events in an automated way that does not capture the required domain knowledge to fit business activities. This can lead to misinterpretation of discovered process models. We developed an approach that aims to abstract an event log to the same abstraction level that is needed by the business. We use domain knowledge extracted from existing process documentation to semi-automatically match events and activities. Our abstraction approach is able to deal with n:m relations between events and activities and also supports concurrency. We evaluated our approach in two case studies with a German IT outsourcing company.

The greenstone belt of Kenya is an extension of what is commonly referred to as the Tanganyika "Shield". The two supracrustal sequences recognized in Kenya are the Nyanzian and the Kavirondian. The rocks found in these sequences are diverse, with dominant volcanics in the Nyanzian, whereas the Kavirondian is predominantly sedimentary. The Nyanzian lavas represent a diverse range from basalts and basaltic andesites, through andesites and dacites to rhyolites. From geochemical studies the basalts and basaltic andesites are tholeiitic, whereas the andesites, dacites and rhyolites are calc-alkaline. The sedimentary sequence ranges from mudstone, through shales, sandstones and grits to conglomerates. The plutonic rocks range in composition from gabbro to true granites, but tonalite is the dominant rock type. The chemical differences between the tholeiitic basalts and the calc-alkaline andesitic to rhyolitic sequences suggests that these volcanic suites are derived from different sources and/or through different processes. The granitoids have close chemical similarities with the silicic volcanics. From the geochemical and field relationships, the Nyanzian and Kavirondian sequences are considered to have developed on a continental segment which had not yet attained full stability. The model employed for the generation of these volcanics considers the basalts to have been generated in a region undergoing extension, similar to that of a modern back-arc environment, whereas the calc-alkaline sequences, including the granitoids, are broadly comparable with those found in present day continental arc environments.

This thesis explores how our notion of mapness is related to our knowledge, reading and understanding of the complex visual language of the map, through an investigation of how we relate to the way maps look and the structures that underpin them.The processes of creating map-like artifacts through the author's own practice are reported upon and inform a drawing forth of historical, theoretical and practical perspectives that act In conjunction to influence the artistic and design expression to communicate mapness.

Diagrams have been used for over a millennium to communicate rich meaning for diverse purposes. Three major and persistent problems concerning our understanding of diagrams have been identified and must be addressed: 1. The variety of diagram types 2. Handling changes while retaining well formedness 3. Semantically mixed diagrams. A variety of both scientific and philosophical approaches to understanding diagrams is examined, and all are found unable to meet these challenges in full.

Meeting future demands of food security will require enhanced rice production that is more environmentally sustainable. To achieve this it is important to know the genetic and molecular mechanism controlling the root traits. High throughput phenotyping which can keep pace with genotyping is needed, but for many researchers this needs to be cheap as well as meaningful. Here a very simple, low cost and reliable method of assessing root depth of seedling using a layer of diuron-soaked filter paper buried 25 cm deep in a soil-filled box has been developed which is suitable for screening of hundreds of accessions. The assumption is that deep-rooting plants die quicker. This method was then used to screen five established rice panels. Deep rooted cultivars were screened from a panel of an aus panel from IRRI and a panel of Brazilian and Japanese cultivars by using this method. Root QTLs were detected by using bi-parental mapping population and GWA study was performed in two panels, the rice diversity panel (RDP-1) and Bengal Assam Association Population. Assessing 139 RILs from Bala x Azucena bi-parental population revealed heritability of 55% for herbicide symptoms where eleven QTLs were detected, many of which were co-localised with previously reported root QTLs in this population. A GWA study was performed using RDP1) of 356 accessions with 44k SNP markers. Analysis revealed 17% of phenotypic variation of herbicide score was attributable to rice sub-population where the aus showed the deepest rooting systems. A number of QTLs have been identified and a number of positional candidate gene lists were produced. A further 298 cultivars from Bengal and Assam were screened and GWA was performed using 2 M SNP database available from sequencing. ANOVA revealed 37% variation for herbicide score explained by genotype. Soil-filled rhizotron were used to assess 12 of these cultivars, revealing strong xx correlations between deep root traits and herbicide score, confirming the reliability of this method. GWA revealed a number of significant SNPs associated with the traits in this population. Finally a set of mutant gene (LOC_Os09g31478, LOC_Os05g40330, LOC_Os11g34140) which are functional candidate gene for root growth QTLs were studied. Here hydroponic phenotypic screening approach were used to identify the T-DNA mutant lines. However, no convincing mutants were revealed. The herbicide screening method has been shown to be a quick and robust system for the assessment of deep rooting rice plants in soil. This method can now be used for screening large number of cultivars and the identification of QTLs and candidate genes.
