Early work has begun in my Michelangelo library that will provide expressive shape-grammars to describe architecture styles or natural shapes based on extrusions, which can then be evaluated on demand to generate optimally-batched meshes and instance-arrays with dynamic level of detail and animated components.

Game Features Micro-Economy Simulation In Citybound, every single household a family or a business is individually simulated.
A utility-based suitability framework for integrated local-scale land-use modelling. Waddell, P. Park, I. Disentangling agglomeration economies: Agents, sources, and spatial dependence. Tiglao, N. Weidner, T. Beckmann, K. Microscopic transport Simulation The efficient flow of traffic through transport infrastructure is vital for a city's health.
Because the road network is subject to frequent change in Citybound, many static pathfinding methods that require long pre-computation but offer fast run-time lookup are unsuitable. Pathfinding information in Citybound is stored in the road network itself and is dynamically updated and propagated through the network, similar to internet routing tables.
Papers: Blatnig, S. Microscopic Traffic Simulation with Intelligent Agents. Liberti, L. Sturtevant, N. Actor-Based distributed simulation Engine Technology To realise Citybound's vision of simulating large-scale cities and streaming them to browsers for interaction, I had to invent and implement quite an unusual computation architecture.
Kay has relatively few features and abstractions in comparison, but that allows a focus on high-performance, with minimal actor and message footprints in memory. The consolidated layout of actor state in memory and the mechanisms for handling broadcast messages that are received by up to millions of actors are heavily inspired by Data Oriented Game Engine Design , the core ingredient in the highly successful pattern of Entity-Component Systems.
RUSt-WASM-JS Bridge Compiling Kay to WebAssembly allows running a fully fledged actor system node in the browser, which can communicate with the simulation backend through type-safe high-performance messages and do computation-intensive preparation work for rendering, before efficiently serialising and passing rendering-relevant information as JavaScript objects to a React app that implements the rest of the UI.
Robust high-performance geometry kernel Almost every object in the Citybound world can be arbitrarily shaped, be it roads, zones or building lots - and their exact shape typically results from complex geometric operations between other objects. Incremental computation framework To provide real-time interactive editing of large city plans and to minimise bandwidth usage between UI and server while streaming plan result previews, it is vital to have a precise formalisation of how changes in plan input affect plan results, and then communicating only the differences.
There are several examples in each section. Use the Public Health Intervention Wheel. Public health nurses and other public health professionals work collaboratively with communities to create environments that promote health and prevent disease and disability.
They use an ecological approach to respond to the needs of the communities and are proactive in program and policy development to enhance the health of populations. Public health nurses use the Nursing Intervention Wheel to define the scope of public health nursing practice by the type of intervention and the level of practice. Regardless of the site or the population, this core set of interventions represents public health nursing as a specialty practice of nursing.
Although developed specifically as a Nursing Intervention Wheel it is easy to see that this broad-based intervention wheel also applies to the practice of many other public health disciplines. This online version of this Public Health Intervention Wheel enhances the original wheel by using visual representations of the interventions by level of intervention in the everyday practice of public health nursing.
Some potential users include:. Medical Reserve Corps. Download the Disaster tool. The After-Action Report assists in identification of key resources that would have been useful during the event, partnerships that need to be created or maintained for the future, and trainings that should be continued or identified to prepare for the next emergency event.
Distributed to emergency responders shortly after an event the tool can be completed in its entirety the emergency responder. The tool is designed to be used in a variety of different event types and jurisdictions. Download the tool. The Public Health Performance Evaluation Primer is similar to a self-audit of public health program activities, and can be used to improve performance within health departments.
The tool recommends methods to measure the efficiency of department processes. The tool assists in facilitating identification of deficiencies that need to be corrected and efficiencies that should be maintained.
The performance information collected by this tool can support resource allocation decisions. With support from the U. Centers for Disease Control and Prevention, we developed the HealthBound policy simulation game for those wanting to experience the possibility of transforming our troubled health system. The model is quantified based on publicly available data from the early s as well as studies from the professional literature on health care utilization and programmatic impact.
The goals are difficult to achieve, in part, because the game includes resource constraints, time delays, and side effects of intervention similar to those of the actual health system.
