Marvis Data Analysis Tool

Marvis Data Analysis Tool

The Marvis application visualizes stored measurements and performs a variety of analysis methods.

The results of a test are stored in measurement archives by the TasAlyser. These archives hold test reports, single values, curve data and spectrograms including the set of active limits at the time of the test.

Marvis loads such archives and displays the data in a configurable way. It is possible to build individual presentations and automate the display of data in these presentations. The graphical data representation can be inserted into Microsoft Office documents via the clipboard. The data themselves can be exported into an Excel compatible file format.

Marvis can load many measurements at one time. It can highlight individual measurements to compare them against a stray band of other data. A sophisticated grouping tool allows to compare different sets of measurements by giving each group a different color, controlling the sequence of plotting and optionally hiding a group. Furthermore, statistical evaluations like averaging can be calculated and displayed in combination with the source data.

Features and Functions

Querying the result database

Querying the result database

The result database is the first choice to retrieve measurements from. Such a Rotas result database can be installed on a server or on the measurement PC itself in case of self-contained analyzer systems. A collector service organizes single measurement archive files into daily archives (among other options) and enters organizational information into this result database.

Marvis can interact with the result database and filter measurements based on properties including time, serial number, test stand, model and result. It is easy to process yesterday's rejects for example.

Another tool to interact with the result database is the Intranet based Web.Pal application which is tuned towards the analysis of rejects and time domain history of single values.

Selecting curve data

Selecting curve data

Curve Data Analysis within Marvis is supported by graphical user interface. Order spectra will show the base order sources of contributing rotors, colors can be assigned to individual measurements and the list of loaded measurements can be sorted and filtered on a variety of criteria.

Data within graphs can be selected by mouse-controlled rectangles resulting both in assigning a different color to them and in highlighting the selected measurements in the load list. This gives a powerful method to filter out units with certain characteristic:

The Statistic Wizard

The Statistic Wizard

Using the Statistics Wizard, Marvis can display single value time domain history and frequency sum distributions. The distributions of several measurements can be compared. The most valuable feature of this Wizard is the variety of possible selection criteria for the data to be analyzed.

Measurement Report

Measurement Report

User defined measurement reports are driven by two key ingredients: An interactive tool for the design of graphic report pages and a macro feature hat automates the display of data in assigned graphics. The graphical elements composing a page include heading titles, logos, curve plots, color plots, waterfall plots, lists and bar graphs. Macros fill those graphical elements with data from the list of loaded measurements. The macros can be interactively recorded and then enhanced with a custom editor or by editing the macro language in source code.
