Robot search and rescue : a comparison of 3D mapping techniques
… extensive knowledge of their surroundings. 3D mapping allows for the creation of such complex maps, and here we explore some of the options available for the creation of 3D maps. We consider using 2D and 3D sensors to see how helpful the extra information is.

Reflected Group Delay method with Space Mapping Techniques for Coupled-Resonator Filter Design
… reflected group delay design approach with space mapping techniques. The theory of the reflected group delay method is discussed in detail. An improvement to the traditional reflected group delay method is proposed in which reflected group delay values at selected sweep frequency points are …

Molecular genetics of Rhodobacter sphaeroides 2.4.1: Genome structure, plasmid characterization and chromosome transfer
Physical mapping techniques were employed to construct both a physical and genetic maps of the Rhodobacter sphaeroides 2.4.1 genome. It was found that this $\alpha$-purple, nonsulfur photosynthetic bacterium carries two different circular chromosomes whose sizes are 3046 $\pm$ 95 and 914 $\pm$ 17 …

Saliency Mapping in Convolutional Neural Networks to Determine Brain Age Trajectories
… Propagation (LRP) and DeepLIFT saliency mapping techniques, analyses were performed on the trained model to determine the most revealing structures over the course of brain ageing for the network, and compare these between the saliency mapping techniques. This work shows the change in …

Multiple transducer synthetic aperture sonar interferometry for emulating SAR interferometry
… air is a technique that can emulate topographic mapping techniques that have not been implemented using radar or that are relatively expensive and difficult to obtain in practice for the radar engineer who wishes to test algorithms using suitable data. This dissertation describes the …

USAGE OF VERY HIGH-RESOLUTION OPTICAL RGB SATELLITE IMAGERY IN GEO-INFORMATION EXTRACTION FOR FINE-SCALE MAP-MAKING
… complexity of modern cities, traditional mapping techniques cannot meet the need for frequent map updates with enriched map details. In this thesis, we investigate how geo-referenced Very High-Resolution optical RGB satellite imagery can be used to extract geo-information to support the …

Automating Topology Aware Mapping for Supercomputers
… ideas, the dissertation proposes algorithms and techniques for automatic mapping of parallel applications to relieve the application developers of this burden. The effect of contention on message latencies is studied in depth to guide the design of mapping algorithms. The hop-bytes metric is …

Comparing mosquito communities of various patch-matrix landscape combinations in central Missouri, with implications for developing models to forecast abundances of important mosquito taxa
… to humans present in these landscapes. Advanced mapping techniques (e.g., GPS, land cover surveys) allow for the characterization of specific locations with regard to landscape, ecological matrix, and the presence of patches of different land cover types within matrices. Thus, coupling biological …

Interaction-Triggered Estimation of AR Object Placement on Indeterminate Meshes
… devices rely heavily on real-time environment mapping to provide convincing world-relative experiences through user interaction with virtual content integrated into the real world. This mapping is obtained and updated through many different algorithms, but often results in holes and other mesh …

The LGBT Community and Public Space: A Mixed Methods Approach
… including a survey, interviews, and hand mapping of emotional associations within the city. Overall, feelings in public space were found to be dependent on an individual's life experiences but several other important themes emerged, such as LGBT spaces as comfortable; the city, parks and …

3D Geologic Mapping and Characterization Using Digital Outcrop Models Generated from Uninhabited Aerial Vehicles and Structure-from-Motion Photogrammetry
… across various scales. Conventional field mapping techniques have remained largely unchanged for the past two centuries and are commonly limited in their ability to quantitatively constrain measurements, extend observations laterally, and document features at multiple scales. Recently, …

An Exploration of Program Mapping and Survey Research Techniques as Ways of Producing Information for Studies of Citizen Participation in Education
The relative worth of two techniques of data collection and analysis, program mapping and survey research, were explored in this study. Specifically, this study was designed to answer the following three questions: (1) Using the survey research and program mapping techniques, what is the nature of …

Genomic analysis of hepatic insulin resistance
… of glucose homeostasis, however, traditional mapping techniques have not been successful in determining all of the genes that regulate glycemia. To complement these efforts, we used DNA microarrays to find differentially expressed genes and combinatorial siRNA screening to investigate the …
