Cooperative Relative Positioning for Vehicular Environments
… Umgebungen wächst die Unsicherheit in der relativen Position. Mit Hilfe der on-board Sensoren können Fehler bei der Fahrt durch Wälder und Dörfer korrekt gestützt werden. In städtischen Umgebungen werden die Limitierungen des Systems deutlich. Durch die erschwerte Schätzung der …

Establishing a relative positioning system to achieve mobile localization
… technologies. To combat this, I propose a relative positioning system between digital devices in order for each device to learn the relative locations of nearby devices. I explore three separate methods of establishing this positioning system. The first uses ultrasonic range-finding to …

Methods for enhancing carrier phase GNSS positioning and attitude determination performance.
… applications which require both a high precision relative positioning and attitude determination system. This is because of the drift-free nature of the GNSS measurement errors and the precise nature of the carrier phase measurement. The key to making full use of the precise nature of the carrier …

Fracturing Illinois: Fields of Political Contention in Hydraulic Fracturing Regulatory Policy
… playing field of political negotiations, and the relative positioning of social movement actors competing for influence in that field. Additionally, I examine the causes and consequences of conflict between coalition partners opposed to fracking, focusing on the impact of differential resources, …

Efficient orchestration of data centers via comprehensive and application-aware trade-off exploration
… to enable precomputation of the required relative positioning of an application's virtual machines (VMs) and allocation of these VMs in a single atomic step, leading to online algorithms that are one order of magnitude faster than existing solutions for placing data center workloads. For …

Filter and bounding algorithm development for a helmet mounted micromechanical inertial sensor array
… to any number of inertial navigators with known relative positioning and attitude coupled using Markov process propagation matrices is also included, along with examples of future applications, in addition to helmet-mounted cueing systems, for vehicle applications.

Increasing Profits from Real Estate Leasing: Flexible Strategies based on Market Conditions
… 10-year, and variable based on understanding of relative positioning within the market cycle. For comparative analysis of these strategies, Monte Carlo simulation via Julia is used to run 10,000 trials for each strategy, calculating the range of outcomes that could occur with each leasing …

A framework for cooperative localization in ultra-wideband wireless networks
… of one or more agents, known as localization or positioning, is a fundamental challenge. Most existing localization methods rely on existing infrastructure and hence lack the flexibility and robustness necessary for large ad-hoc networks. In this thesis, we describe a framework for localization …

Hard or soft skills? : how the Erasmus plus project leaders view the relative importance of skills when it comes to conducting their projects
… The aim of this paper is to evaluate the relative positioning of hard and soft skills within the current processes of application, preparation and support provided by the E+ programme, and contrast to the skillsets which project managers leading these projects find most relevant when …

Cooperative localization for autonomous underwater vehicles
… challenging due to the absence of Global Positioning System (GPS) reception or features at known positions that could otherwise have been used for position computation. Thus Autonomous Underwater Vehicle (AUV) applications typically require the pre-deployment of a set of beacons.This …

Twofish: Automatic Edit Cascading for Diagrams
… the change to the diagram. This is because these relative positioning constraints are often defined through layout commands, such as alignment, which are viewed by many direct manipulation editors as one-time operations. That is, a layout command enforces spatial relationships between objects by …

Geometric modeling of manufacturing processes variations for model-based tolerance analysis
… introduced. For assembly tolerance analysis, a relative positioning scheme capable of modeling the interaction between mating splines was developed to propagate the individual part variations within the assembly. This enabled the tolerance stackup on the assembly design function(s) to be …

Multiple Mobile Robot SLAM for collaborative mapping and exploration
… this, AMRs needs to localise themselves reliably relative to the map. Simultaneous Localisation and Mapping (SLAM) address the problem of both map building and robot localisation. When exploring large areas, Multi-Robot SLAM (MRSLAM) has the potential to be far more efficient and robust, while …

Topology of Genes in Mammalian Cell Nuclei with Special Emphasis on the MLL Gene and Its Translocation Partners
… cells. The nuclear localization of a gene relative to the nuclear center and the nuclear periphery was determined. To provide a general understanding of the distribution pattern of a given locus within the nucleus, the nuclear volume was divided into five concentric shells in two different …

Building bridges: Introducing concepts from neuroscience and attachment theory to person-centred practitioners
… this is an important issue that relates to the relative positioning and competition between different ‘modalities’ in the field of psychotherapy. The project centres on the development of a series of workshops that bring together the two areas referred to above in the context of a learner …

Regulatory Landscapes Associated With Changes In Nuclear Architecture
… by the cell’s chromatin architecture. Gene positioning relative to the center of the nucleus or its three-dimensional contacts with other genomic regions can determine whether the gene is expressed or not. Changes in chromatin architecture have been reported in cell differentiation contexts, …

Uncovering Biophysical Determinants Of Oxidoreductase Function Through De Novo Protein Design
… protein scaffold, which via microenvironment, relative positioning, geometric strain, and other mechanical properties modulate the energetic landscape and gate the influx and efflux of reactants and products. Separation of these aspects in practice, however, is often hindered by the sheer …

Highline Rescue Boat Systems: A study of the load created by tethered rescue boats with respect to stream velocity, trim and hull size.
… vector. The independent variables of trim (relative positioning of the load within the boat) and average stream velocity were investigated. Under low flow conditions, when trimmed neutrally (the crew were positioned centrally), the Eurocraft induced the highest force on the high line …

Investigating Cellular and Molecular Mechanisms of Neuronal Layering in Self-Organising Aggregates of Zebrafish Retinal Cells
… although all cell types are layered in the same relative order as they are in vivo. To analyse the organization in these aggregates I developed a Matlab script in collaboration with Leila Muresan which analyses the relative positioning of cells in concentric rings from the periphery to the centre …
