The following is a screenshot tour of the
MMSS TimeLine and serves as a walkthrough of the various features of
the implemented TimeLine system. Two versions of TimeLine have
been implemented; one for the medical domain and one for the
geophysical domain. The papers published present the motivation and highlights of the R&D that these sreeen shots illustrate.
The Medical TimeLine allows users to view patient data via the
timeline paradigm. The current version of TimeLine provides
views for displaying (Picture Archiving and Communication System) PACS
images and Vivometric
LifeShirt
signals. The available PACS image database included 16 patients,
totaling 16 computed radiology, 267 computed tomography, and eight
magnetic resonance images, totaling 291 images. The available Vivometric
LifeShirt data used in this test-bed included six patient studies,
totaling 24 hours of monitoring data for 117 separate signals and
derived trends. All real patient identification and names were
replaced with psuedo-names to maintain patient confidentiality.
The Geophysical TimeLine allows users to view geographic data via the
timeline paradigm. The current version of TimeLine provides views for
displaying NASA MODIS
satellite Land Surface Temperature data,
CapeScience GlobalWeather Web service data, and
National Weather Science radar
images. The available MODIS data included eight data instances of the
LST data type. The CapeScience data consisted of one data instance
with the five data types of temperature, pressure, wind, direction,
wind speed, and humidity. The National Weather Science radar images
provided consisted of one image instance and had the three image types
of reflectivity, last hour precipitation, and storm total
precipitation
Both TimeLine applications, and the overall system, were impemented
using various techonogies, including:
-
JAI, Java
Advanced Imaging API used for image processing in Java.
-
XML,
Extensible Markup Language used for describing and exchanging data.
-
JDO,
Java Data Objects API used for connectivity to object-oriented
databases, such as
FastObjects t7.
-
JDBC, Java Database
Connectivity API used for connectivity to relational databases, such
as IBM DB2.
-
SOAP,
Simple Object Access Protocol used for inter-application communication
across the web.
-
HDF,
Hierarchical Data Format used by NASA to store satellite data.
-
IDL/ION,
Interactive Design Language/IDL on the Net application tools used for
building visualization components for Java.
-
Swing,
Graphical user-interface classes for Java.
-
E-gantt,
An open-source implementation of a Gantt chart in Java.
