Designing a Language for Spatial Computing
•
1 like•618 views
This document presents a design for a language for spatial computing. It discusses core concepts of spatial information like fields, objects, networks and events. It uses the example question "How long will a hill walk take?" to illustrate how spatial questions can be answered using core computations in GIS like analyzing granularity and accuracy. The goal is to develop high-level query operators, validate them in projects and create generic APIs for spatial question answering.

The document discusses the Geological and Mining Department of Suriname's use of ArcGIS software to digitally map mining concessions. It notes that previously mapping was done offline, but in August 2017 the Ministry of Natural Resources launched an online GMD website hosting the mining concession maps. The website, accessible at a given URL, features an interactive map of gold and building material concessions as well as examples of how ArcGIS allows joining related tabular data. It highlights that the website benefits students, investors, entrepreneurs and other government ministries in Suriname.
Time Manager Workshop at #QGIS2015 Conference in Nodebo
This talk presents QGIS visualization tools with a focus on efficient use of layer styling to both explore and present spatial data. Examples include the recently added heatmap style as well as sophisticated rule-based and data-defined styles. Additionally, we will have a special look at exploring and presenting spatio-temporal data using the Time Manager plugin. As a special treat, we will look into creating time-dependent styles using expression-based styling to access the current Time Manager timestamp.
The second part is a workshop about hands-on experience with Time Manager. Time Manager makes it possible to explore spatio-temporal data by creating animations directly in QGIS. We’ll cover data requirements, configuration, as well as time-dependent styling and creating animations.Visual exploration and presentation of spatial data using QGIS

capital bikeshare
The document describes a study analyzing bike share usage patterns in relation to metro station locations. It used CSV data on bike share departures imported into Pandas to identify the most used stations. Stations in the top quarter were analyzed in relation to buffer zones around metro stations, finding that metro proximity influences bike share usage, especially during commuting hours. Challenges included formatting the data and some issues importing CSVs into ArcGIS. In conclusion, metro locations near bike share stations affect bike rental numbers, with most top stations located within a quarter mile of metro entrances.
Network Rail - Esri UK Annual Conference 2016
This document discusses Network Rail's use of GIS systems to evaluate and manage their earthworks assets without needing physical inspections. It details how they used aerial imagery, LiDAR data, and automated extraction of slope and geometry information from over 800,000 cross-sections to analyze 150,000 sites that had never been inspected before. This reduced the number of never-inspected sites from 36,000 to under 6,000 and saved an estimated £1.2 million by avoiding manual inspections. The methodology developed is now being applied nationally to verify all of Network Rail's earthworks assets and gain a complete picture of their geometry for the first time.
Sample Works
The document presents renderings, plans, and diagrams for various architectural, interior design, planning, and sustainability projects. The projects cover residential, commercial, academic, and urban development across multiple locations. Software such as AutoCAD, Revit, SketchUp, and ArcMap GIS were used to create the visualizations.
BIM - Esri UK Annual Conference 2016
GIS can be used throughout the entire building lifecycle from planning and design through to operation. During the planning stage, GIS is useful for understanding geographic context and constraints. In design, GIS allows presentation of concepts to stakeholders and procedural modelling of design options. GIS supports analysis of design options and engagement. It also enables positional quality assurance. During construction, GIS supports site operations management. In operation, GIS facilitates facilities management and operational efficiency through integration with other systems like SAP and SharePoint. The customer's data requirements should be specified to ensure the right digital information assets are delivered.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.
