7th February 2008
Tommi Borg gives an oral presentation at XVth Int. Congr. on Rheology August 3-8, 2008 in Monterey, California USA, where are further developments presented starting principles used by RheoPower and DataPower.

22nd October 2007
In the new RheoPower 3.1 version is added component to use the present IUPAC Schema for XML Datafiles. Only by one buttons click RheoPower can import measured data or export computed results to the XML file. Software will be updated immediately according to new suggestions by IUPAC standardisation project.

7th April 2007
New RheoPower version 3.0 is coded strictly according to developed principle based on the very recently found and elsewhere certified physical relations. Software itself has worked well during years. –The wanted background turned finally to the simple form but very new in rheology. New licensing system is introduced to the packages.

Tommi Borg gives an oral presentation at AERC 2007, 4th Annual European Rheology Conference April 12-14 in Napoli, where these new fundamental findings are presented.

7th April 2006
To the RheoPower version 2.11 is added option for jointing data from different sources as from oscillating and capillary rheometers to the same analysing procedure.

DataPower Server version 2.7 includes pressure influences to the output viscoelastic and orientation data.

26th October 2005
New RheoPower version 2.10 can use data measured by capillary rheometer besides dynamic data from oscillating rheometer. Option to use also relaxation modulus G(t) data and now we get accurate value for zero viscosity.

RheoPower for DataPower version can produce material data files for DataPower server, which feeds CAE/CAD/CFD simulation software packages.

New DataPower Server version 2.4 feeds accurately data and can be simulated earlier impossible case. We get simultaneously accurate orientation charts.

16th November 2004
New RheoPower version 2.09 can use measured data of relaxation modulus G(t) and shows accurate value for zero viscosity.

The secrets of computation are more visible on the function charts and the kernel of principle called functional distribution is introduced. Wizards are added to help Quick Start.

21st July 2004
Totally refreshed web pages and new DataPower Software Family is introduced for CAE/CAD/CFD simulation business range.

Tommi Borg gives two oral presentations at XIVth Int. Congr. on Rheology August 22-27, 2004 in Seoul, Korea and there is rented an exhibition booth for principle presentations and simulations with PC.

21st May 2003
RheoPower version 2.07 has some minor changes and also suitable for Windows XP platform styles.

26th August 2002
Finally the Manual of 170 pages is ready and proof-read. Also Contents Help of RheoPower has been enewed and proof-read. New Version 2.06 has some minor changes. We studied the background of the differential equations and re-wrote some basis of the principle.
