Full textENGLISH ABSTRACT: Knowledge Transfer is one of the key knowledge management practices that organisations employ to ensure cross-pollination of knowledge across their various divisions. It should be a cornerstone of a learning organisation and should pervade the entire organisation in all its manifestations. In general it is a question whether public sector organisations in South African are employing such practices in their quest to render services effectively, efficiently and economically. This thesis focuses on an attempt at knowledge transfer in a department in an underdeveloped province, i.e. the Department of Roads and Public Works in the Eastern Cape. It centres on a case study of Cuban engineers who were contracted by the South African government to design and build infrastructure. The thesis is divided into the following chapters: Chapter 1: deals with the problem of knowledge transfer in a developing context. The chapter focuses on the objectives of the research and sketches a contextual backdrop to the study. Chapter 2: discusses the key concepts of Learning, Organisational Learning, Knowledge, Knowledge Transfer, and Knowledge Transfer Strategies. It also identifies barriers to knowledge transfer and highlights a few suggestions on how to deal with those barriers. Chapter 3: deals with the case study of six Cuban engineers and presents the results of the case study. Chapter 4: describes some of the local initiatives taken by the Department to cater for the needed skills in their sector. Chapter 5: evaluates the topic by bringing the literature discussed in chapter two to bear on the findings of the case study.
AFRIKAANSE OPSOMMING: Kennisoordrag is een van die kern kennisbestuurspraktyke waardeur organisasies kruisbestuiwing van kennis oor ‘n verskeidenheid onderafdelings moontlik maak. Dit behoort die basis van ‘n ‘learning organisation’ te wees en die hele organisasie te deursuur. In die algemeen is dit ‘n vraag of publieke sektor organisasies in Suid-Afrika sodanige praktyke aanwend in hulle pogings om dienste te lewer. Hierdie tesis fokus op ‘n poging tot kennisoordrag in ‘n departement wat in ‘n onderontwikkelde provinsie in Suid-Afrika geleë is, naamlik die departement Paaie en Openbare Werke in die Oos-Kaap. Die tesis draai om ‘n gevallestudie van Kubaanse ingenieurs wat deur die Suid-Afrikaanse regering gekontrakteer was om infrastruktuur te ontwerp en te bou. Die tesis is verdeel in die volgende hoofstukke: HOOFSTUK 1 handel oor die probleem van kennisoordrag binne ‘n ontwikkelingskonteks. Dit sit die doel van die studie uiteen en beskryf die sosiale konteks daarvan. HOOFSTUK 2 bespreek die kernkonsepte, naamlik Leer, Organisatorise Leer, Kennis, Kennisoordrag en Kennisoordragstrategieë. Dit identifiseer ook faktore wat kennisoordrag teenwerk en bespreek moontlike oplossings vir laasgenoemde probleem. HOOFSTUK 3 behels ‘n gevallestudie van 6 Kubaanse ingenieurs en bied die resultate daarvan aan. HOOFSTUK 4 beskryf sommige lokale inisiatiewe deur die Department om kennisoordrag te bevorder. HOOFSTUK 5 evalueer die onderwerp deur die literatuur in hoofstuk 2 in verband te bring met die gevallestudie.

Full textThis thesis addresses the critical challenge of “sparse data and scarce knowledge” in developing a generic Prognostics and Health Management (PHM) model. A comprehensive literature review highlights the efficacy of hybrid models combining physics-based modeling with machine learning, focusing on Physics-Informed Machine Learning (PIML) and Self-Supervised Learning (SSL) for enhanced learning from unlabeled data. Thereby, this thesis contributes to advancing both PIML and SSL theories and their practical applications in PHM.The first contribution is developing a generic architectural and learning strategy solution for PIML. Various informed approaches are analyzed, and the mimetic theory is proposed to design flexible, physically consistent neurons and interlayer connections. This novel approach leads to the development of the Rotor Finite Elements Mimetic Neural Network (RFEMNN), which mimics rotor finite element-based dynamics to adjust weight distribution and data flow within the neural network. RFEMNN effectively localizes and recognizes compound faults across multiple rotor structures and conditions. To enhance RFEMNN's few-shot diagnostic capability, constraint projection theory and a reinforcement learning strategy are proposed, aligning the learning process with physics. A generic PIML architecture with parallel, independent PI and data-driven branches is proposed, involving a three-stage training process: pre-training the data-driven branch, freezing it to train the PI branch, and joint training of both branches. This method combines optimized local branches into a comprehensive global model, ensuring the PIML model's performance exceeds original data-driven models under spare data context. Moreover, the solid electrolyte interphase growth-informed Dilated CNN model using this approach showcases its superiority, surpassing leading models in predicting lithium-ion battery RUL with small-cycle data.The second contribution is developing an innovative SSL strategy for unlabeled data learning, introducing a Siamese CNN-LSTM model with a custom contrastive loss function. This model extracts robust feature representations by maximizing differences in the same samples presented in varied sequential orders. Variants of downstream tasks are proposed as intermediate objectives in SSL pretext learning, integrating downstream structures into the pre-training model to align representations with downstream requirements. Under this strategy, the proposed Siamese CNN-LSTM excels at predicting RUL on PRONOSTIA-bearing dataset and remains stable even as training data sparsity increases.The final contribution extends PIML concepts for active knowledge discovery on unlabeled data and integrates SSL into the second phase of PIML's three-step training, utilizing both labeled and unlabeled data. A novel Liquid PI structure and an end-to-end Liquid PI-CNN-Selective state space model (CNN-SSM) are developed. The Liquid PI design introduces gated neurons and liquid interlayer connections that adapt dynamically, acquiring physics knowledge through an optimized search within a predefined operator pool. Demonstrated in torque monitoring of robot manipulators, this approach efficiently discovers knowledge using basic physical operators and dynamic weights from unlabeled data. The Liquid PI CNN-SSM processes variable-length input sequences without signal preprocessing, optimizing resources by requiring only 600 KB to handle 23.9 GB of data. It achieves state-of-the-art performance in mixed prognostic tasks, including bearing degradation, tool wear, battery aging, and CFRP tube fatigue, showcasing the originality and versatility of the proposed approach.Future work will apply PHM-specific scaling laws and train on extensive synthetic and industry datasets to build a cross-modal macro-model. It could integrate diagnostic-prognostic capabilities with infinite sequence length processing, continuing to transform PHM methodologies and solutions

Full textThe effects of changes in elevation, route distance, route complexity, and non-spatial information on memory for a virtual environment were investigated. Thirty college students learned the layout of a two-story virtual environment through a series of navigation tasks. Participants were required to learn the route from a starting point to each of 14 rooms in the environment. After completing six blocks of learning trials, the participants estimated route distances and directions, completed a priming task in which they identified the floor that each room was on, and navigated novel routes that were not traversed in the learning trials. The results indicated that the elevation, route distance, and route complexity, affected both learning and memory for the environment. In contrast, non-spatial information had no effect on memory for room location or the layout of the virtual environment.

Full textHow can we accumulate knowledge on brain functions? How can we leverage years of research in functional MRI to analyse finer-grained psychological constructs, and build a comprehensive model of the brain? Researchers usually rely on single studies to delineate brain regions recruited by mental processes. They relate their findings to previous works in an informal way by defining regions of interest from the literature. Meta-analysis approaches provide a more principled way to build upon the literature. This thesis investigates three ways to assemble knowledge using activation maps from a large amount of studies. First, we present an approach that uses jointly two similar fMRI experiments, to better condition an analysis from a statistical standpoint. We show that it is a valuable data-driven alternative to traditional regions of interest analyses, but fails to provide a systematic way to relate studies, and thus does not permit to integrate knowledge on a large scale. Because of the difficulty to associate multiple studies, we resort to using a single dataset sampling a large number of stimuli for our second contribution. This method estimates functional networks associated with functional profiles, where the functional networks are interacting brain regions and the functional profiles are a weighted set of cognitive descriptors. This work successfully yields known brain networks and automatically associates meaningful descriptions. Its limitations lie in the unsupervised nature of this method, which is more difficult to validate, and the use of a single dataset. It however brings the notion of cognitive labels, which is central to our last contribution. Our last contribution presents a method that learns functional atlases by combining several datasets. [Henson 2006] shows that forward inference, i.e. the probability of an activation given a cognitive process, is often not sufficient to conclude on the engagement of brain regions for a cognitive process. Conversely, [Poldrack 2006] describes reverse inference as the probability of a cognitive process given an activation, but warns of a logical fallacy in concluding on such inference from evoked activity. Avoiding this issue requires to perform reverse inference with a large coverage of the cognitive space. We present a framework that uses a "meta-design" to describe many different tasks with a common vocabulary, and use forward and reverse inference in conjunction to outline functional networks that are consistently represented across the studies. We use a predictive model for reverse inference, and perform prediction on unseen studies to guarantee that we do not learn studies' idiosyncrasies. This final contribution permits to learn functional atlases, i.e. functional networks associated with a cognitive concept. We explored different possibilities to jointly analyse multiple fMRI experiments. We have found that one of the main challenges is to be able to relate the experiments with one another. As a solution, we propose a common vocabulary to describe the tasks. [Henson 2006] advocates the use of forward and reverse inference in conjunction to associate cognitive functions to brain regions, which is only possible in the context of a large scale analysis to overcome the limitations of reverse inference. This framing of the problem therefore makes it possible to establish a large statistical model of the brain, and accumulate knowledge across functional neuroimaging studies
