The QFView framework
and maintain the metadata repository. The user can accomplish the following tasks
using this thin GUI Java client:
• Start the GUI Java client application, create a new folder (measurement), define
metadata information for the folder, such as keywords, physical characteristics,
etc. It is important to emphasize that the GUI Java client is connected to the
EJB server using the http protocol, and all the information entered by the user
are automatically stored in the relational database.
• Organize the data into a hierarchy of predefined or newly created tree-like
nodes; user can also execute a data search procedure, combine documents, and
do several other operations on the input folder.
• Create and define new raw data such as XML files, images, input files, etc. for a
particular folder by specifying either a local or a remote location of the data.
• Define old raw data (XML files, text files, videos, etc.) by specifying either a
local or a remote location of the data.
• Start the visualization plug-in application on the selected raw data.
Essential Database Tools present in QFView are:
(a)
Data entry
(b)
Folder and document insertion
(c)
Data classification
(d)
Full text search
(e)
Meta model and data organization
These tools were used to assist experimental setup, to improve data acquisition
and systematic manipulation of the results of the VUB's double-annular jet
modeling (Fig.

, frame 1 from left) of the flow in a prototype combustion
chamber. The requirement was to analyze the flow from LSV data (frame 2), PIV
data (frame 3), LDV data (frame 4), and CFD calculation data (frame 5). The LDV
(frame 4) clearly shows the mean flow field, which can be compared with CFD
(frame 5). Qualitatively they produce a similar topology but the prediction is not
