This thesis reports research on mapping, path planning, and autonomous exploration. These are classical problems in robotics, typically studied independently, and here we link such problems by framing them within a common SLAM approach, adopting Pose SLAM as the basic state estimation machinery. The main contribution of this thesis is an approach that allows a mobile robot to plan a path using the map it builds with Pose SLAM and to select the appropriate actions to autonomously construct this map. Pose SLAM is the variant of SLAM where only the robot trajectory is estimated and where landm

The use of multirotor UAVs to map GPS-degraded environments is useful for many purposes ranging from routine structural inspections to post-disaster exploration to search for survivors and evaluate structural integrity. Multirotor UAVs are able to reach many areas that humans and other robots cannot safely access. Because of their relatively short operational flight time compared to other robotic applications, using multiple UAVs to collaboratively map these environments can streamline the mapping process significantly. This research focuses on four primary areas regarding autonomous mapping a

Vegetation mapping is often considered the process of identifying landscape patterns of individuals or clusters of species or life forms (LF). At the landscape scale, the larger pattern represented by individuals or clusters represents the conceptualization of "vegetation mapping" and can be used as a building block to describe an ecosystem. To represent these building blocks or LF a "common entity (CE)" concept is introduced to represent the components of Formations as described by the National Vegetation Classification (NVC) system. The NVC has established protocols to consistently represent

Cotton is a crop with a large global economic impact as well as a large, complex genome. Most industrial cotton production is from two tetraploid species (Gossypium hirsutum L. and Gossypium barbadense L.) which contain two subgenomes, specifically the AT and DT subgenomes. The DT subgenome is nearly half the size of the AT subgenome in tetraploid cotton and is closely related to an extant D-genome Gossypium species, G. raimondii Ulbr. Characterization of the structural variants present in diploid D-genome should provide greater insight into the evolution of the DT subgenome in the tetraploid

This thesis addresses issues which arise when using robotic platforms to explore large-scale, natural environments. Two main problems are identified: the volume of data collected by autonomous platforms and the complexity of planning surveys in large environments. Autonomous platforms are able to rapidly accumulate large data sets. The volume of data that must be processed is often too large for human experts to analyse exhaustively in a practical amount of time or in a cost-effective manner. This burden can create a bottleneck in the process of converting observations into scientifically rel

It focuses on the effectiveness of ASTER and Landsat 8 optical multi-spectral satellite imagery for discerning the spectral properties of different bedrock and surficial materials that outcrop or blanket the regional terrain. Statistical algorithms and digital image enhancement techniques were used to highlight patterns and anomalies within each scene in order to determine the range of materials and specific deposits (e

Thesis (MBA)--Stellenbosch University, 2015.<br>ENGLISH ABSTRACT: In a global era of growing consumer economies, retailers rely extensively on the exploitation of consumers’ personal and behavioural information, in order to successfully execute and sustain their business models and strategic objectives. The gathering and mining of consumers’ personal and behavioural information represent tremendous potential in the application of relationship marketing tactics, towards consumer intimacy, and ultimately towards competitive advantage. However, in their quest to understand consumers better,

The affective and neurological components of information retrieval system design have increasingly become an essential part of research in human-information interaction and interactive information retrieval. These sophisticated processes are composed of not only human cognitive processes but also emotional and neuropsychological responses. This research contributes three original findings to the field of Information Science, positioned in Neuro Information Science. This experimental research 1) mapped the neurophysiological dimensions of information search processes model, 2) integrated the th

Autonomous underwater vehicles are used nowadays in many applications. One of the applications is mapping of a particular area of the ocean. Quen the robot needs to cover the area of interest and no prior knowledge of the area to be covered is avaialbe, a robotic exploration algorithm is used. This thesis develops a robotic exploration algorithm for autonomous underwater vehicles. The proposed algorithm allows the full exploration of a 2D or 3D environment, using acoustic sensors such as a scanning profiling sonar or a multibeam, and optical cameras. The validity of the proposed algorit

Dans la communauté robotique aérienne, un croissant intérêt pour les systèmes multirobot (SMR) est apparu ces dernières années. Cela a été motivé par i) les progrès technologiques, tels que de meilleures capacités de traitement à bord des robots et des performances de communication plus élevées, et ii) les résultats prometteurs du déploiement de SMR tels que l’augmentation de la zone de couverture en un minimum de temps. Le développement d’une flotte de véhicules aériens sans pilote (UAV: Unmanned Aerial Vehicle) et de véhicules aériens de petite taille (MAV: Micro Aerial Vehicle) a ouvert la

It has become increasingly clear that dealing with present day environmental crises requires a holistic view that takes into account the interactions of social and ecological factors across multiple spatial and temporal scales. An example of where this new paradigm is being operationalized is the study of social-ecological systems. A substantial aspect of this growing research area aims to contribute to a more comprehensive understanding of the links between social-ecological systems, the ecosystem services they generate, and human well-being. This thesis summarizes the first part of a PhD pro

Maps have longed been recognized as instruments of power and persuasion. With the recent proliferation of maps in the media and on the Internet has come an increasing desire among groups advocating for environmental and social change to have access to maps (the product) and mapping (the process) to more effectively promote their agendas. However, this is not as simple as it seems. Far from being neutral conduits of "truth," maps are constructed by a myriad of social interactions among heterogeneous actors (human and technical) that left unacknowledged can lead to an untapped potential of the p

This research has explored lay and professional understandings of a 'good death' and the spiritual dimension of care within a hospice in Ireland, and the extent to which culture shaped understanding. Palliative care has been largely developed in the UK and the U.S, societies with a strong emphasis on individualism, which is not present to the same extent in Ireland. No previous research has considered these aspects within palliative care in Ireland. The research has utilised a cartographic approach - as an organising principle, as a methodological approach and as a way of understanding the rel
