Eternal Flames: Living Memories of the Pacific War

Funds requested for an innovative website that provides a living archive of Pacific War memories in multiple languages. Our prototype provides a social media and multi-lingual database structure enabling communication between researchers, war survivors, and the general public in English, Japanese, Chinese, and Korean. This site facilitates research on the circulation of war memories throughout the Pacific region and across linguistic boundaries. Online participants will transcribe, translate, tag, and add context to user-contributed archive posts. The architecture makes transparent the negotiations and contested categories of memory-in-translation. In this online environment, users can confront the cultural embeddedness of language, and researchers can trace the transformations of memory as it travels across cultural boundaries. As an open source tool, our online platform can be applied in various contexts to address the language barrier issue that is so central to the humanities

Visualization Tools for Data Assimilation

Weather forecasts are typically produced once or twice each day. Each run usually covers several forecast periods. Over the course of the day, as measured sensor data becomes available, discrepancies between observations and model forecasts are resolved and integrated so as to update and improve the next forecast run. The process of resolving the differences between model output and sensor measurements is known as data assimilation. Traditional methods include kriging and optimal interpolation. They involve statistical and historical information on reliability of sensor measurements (including desirability of sensor location, calibration, etc.), variability of the field, model resolution, initial and boundary conditions, etc. Some of the parameters of a data assimilation model are integration techniques, choice and frequency of incremental update methods, interpolation algorithms, resolution of the model grid, estimation filtering and smoothing algorithms and finite differencing scheme..

Visualization Products On-Demand Through the Web

We describe our efforts in providing REINAS (Realtime Environmental Information Network and Analysis System) weather visualization products on demand through the web. As the REINAS research enterprise transition into operational mode, there is increasing demand for wide and effective distribution of results. To meet this demand, we provide weather products on the web as both images and VRML worlds. The viewer selects geographic extents and time range, as well as specific weather products. Data is then pulled out of the database based on the user's specifications and fed to the visualization tools to produce the image or VRML file. This paper describes the architecture of this end-to-end system for delivering sensor and forecast data through the database and to the public as VRML-based visualization products. Key wordsand phrases: VRML, HDF, database, environmental visualization, weather, data fusion, data assimilation. 1 INTRODUCTION As the Internet becomes commonplace, there is a gr..

Integrated Visualization of Realtime Environmental Data

This paper presents the visualization effort of the REINAS (Realtime Environmental Information Network Analysis System) project. REINAS is a continuing engineering research and development system with the goal of designing, developing and testing an operational prototype system for data acquisition, data management, and visualization. It includes a growing web of networked remote and in-situ instruments, a federated geographical database, and an extensible visualization interface. REINAS focuses on the needs of both oceanographers and meteorologists who monitor realtime data or analyze retrospective data. The visualization system of REINAS provides an integrated access via a distributed database to a host of different realtime data sources, numerical model forecasts, as well as more static data sets such as coastline and terrain information. It is designed as a modular tool-based system where users activate the appropriate visualization tools to generate different types of visualizatio..
