Thesis (MA (Afrikaans and Dutch))—University of Stellenbosch, 2009. / AFRIKAANSE OPSOMMING: In hierdie verhandeling word die briewe, wat Uys Krige tydens sy verblyf in Frankryk en Spanje tussen die jare 1931 en 1935 aan sy gesin en vriende geskryf het, in ’n geredigeerde vorm uitgegee, terwyl annotasies verskaf word waar dit nodig is om spesifieke persone te identifiseer en sekere gedeeltes, sover dit agterhaalbaar is, te verhelder. Op dié wyse sal Krige se briewe teen die agtergrond geplaas word van die Mediterreense wêreld wat hy in dié tydvak leer ken het. Terselfdertyd sal die groeiproses belig word wat hy as skrywer in hierdie belangrike fase van sy lewe deurgemaak het. Die hoofdoel van die studie is om, uitgaande van die beginsels van die hedendaagse edisiewetenskap, ’n leesbare teks te konstitueer wat egter steeds getrou aan Krige se oorspronklike briewe sal bly. Deur só ’n teks tot stand te bring, word terselfdertyd tot dusver grotendeels onbekende fasette van ’n prominente Afrikaanse skrywer bekend gestel. Die oorspronklike briewe is almal per hand geskryf en is aan die Nasionale Biblioteek in Kaapstad deur J.G.J. (Bokkie) Krige geskenk. Hy het egter eers die briewe oorgetik en in vier leergebonde bundels laat inbind wat tans in die besit is van Eulalia Krige, die dogter van die skrywer. ’n Fotokopie van die getikte briewe dien as die uitgangspunt van hierdie studie. Dit word getranskribeer, versorg en met die oorspronklike briewe vergelyk om te verseker dat die tekste korrek oorgetik is. Die briewe van Uys Krige aan sy familie, wat in hierdie studie opgeneem word, strek tussen die jare 1931, wanneer Krige, kort ná sy aankoms uit Londen, hom in die suide van Frankryk vestig, tot November 1935, wanneer hy uit Spanje, ná die publikasie van sy debuutbundel Kentering, na Suid-Afrika terugkeer. / ENGLISH SUMMARY: In this dissertation the letters of Uys Krige, which was written during his stay in France and Spain between the years 1931 and 1935, to his family and friends, are produced in an edited form, whilst annotations are provided where necessary to identify specific people and to, where possible, clarify some of the written parts. Thus Krige’s letters will be placed against the backdrop of the Mediterranean world which he came to know during this era. At the same time Krige’s growth as writer, which excelled during his European stay, will be highlighted. The aim of this dissertation is to construct a readable text which remains faithful to the original writings, based on the principles of the modern science of editions. By producing such a text, some previously unknown facets of a prominent Afrikaans writer are also brought to light. The original letters are all hand-written and were donated to the National Library in Cape Town by Krige’s brother, J.G.J. (Bokkie) Krige. However, the latter retyped these letters and bound it in four leather collections which are now in the possession of Eulalia Krige, the writer’s daughter. Photocopies of the letters serve as the starting point for this study. It is transcribed, edited and compared with the original letters to ensure the letters were retyped correctly. The letters of Uys Krige to his family which are collected in this dissertation stretch from 1931, when Krige, shortly after his arrival from London, finds himself in the south of France, until November 1935, shortly after the publication of his debut poetry collection Kentering and before he heads back to South Africa.

Many geological deposits contain nonlinear anisotropic features such as veins, channels, folds or local changes in orientation; numerical property modeling must account for these features to be reliable and predictive. This work incorporates locally varying anisotropy into inverse distance estimation, kriging and sequential Gaussian simulation. The methodology is applicable to a range of fields including (1) mining-mineral grade modeling (2) petroleum-porosity, permeability, saturation and facies modeling (3) environmental-contaminate concentration modeling. An exhaustive vector field defines the direction and magnitude of anisotropy and must be specified prior to modeling. Techniques explored for obtaining this field include: manual; moment of inertia of local covariance maps; direct estimation and; automatic feature interpolation. The methodology for integrating locally varying anisotropy into numerical modeling is based on modifying the distance/covariance between locations in space. Normally, the straight line path determines distance but in the presence of nonlinear features the appropriate path between locations traces along the features. These paths are calculated with the Dijkstra algorithm and may be nonlinear in the presence of locally varying anisotropy. Nonlinear paths do not ensure positive definiteness of the required system of equations when used with kriging or sequential Gaussian simulation. Classical multidimensional scaling is applied to ensure positive definiteness but is found to be computationally infeasible for large models, thus, landmark points are used for efficiency with acceptable losses in precision. The methodology is demonstrated on two data sets (1) net thickness of the McMurray formation in northern Alberta and (2) gold grade in a porphyry copper deposit. Integrating LVA into numerical modeling increases local accuracy and improves leave-one-out cross validation analysis results in both case studies. / Mining Engineering
