UpenWin is a 32 bit application for Windows (currently tested under windows 98, XP and Vista), developed in C++ and MFC (Microsoft Foundation Class) by means Visual Studio 2005, that implements an interface to facilitate the use of UPEN (Uniform PENalty) and its related input files. It is composed by a simple SDI (Single Document Interface) window with many dialog boxes. By means of the dialogs the user can pre-process the data file using the appropriate program filter, sets the value for the parameters, both for UPEN and programs filter, and runs a computation session. Parameters can be set also in the initial parameter file, by clicking the “par” menu button and proceeding to the desired parameter file (such as Upenpar.par), making any needed changes, and saving or not saving as desired. UPEN is an executable (binary format) for Windows platform, developed in True Basic, that implements a new robust algorithm for the inversion of multiexponential decay data. The name refers to the application of negative feedback to a smoothing “penalty” function to prevent excessive detail in distributions of relaxation times. This allows appropriate smoothing of both sharp peaks and broad features in the same distribution, allowing the sharp peaks without breaking broad features into multiple peaks not required by the data. This allows meaningful computation of the rms noise and supports additional UPEN objectives, which include identifying various data features and data problems (such as data not precisely fitting the model of multiexponential decay plus random noise), giving a series of diagnostics and warnings and allowing processing options where needed. There are many adjustable parameters in UPEN, most of which need not and should not be adjusted except in specialized circumstances or in basic investigation of UPEN function. The input data file for UPEN is a binary file produced by any of several preprocessing “Filters”. UPEN is an iterative inversion computation, and the evolving distributions and various computed quantities are shown at each iteration. When computation is complete, two text files are produced.

Abstract
UpenWin is a 32 bit application for Windows (currently tested under windows 98, XP and Vista), developed in C++ and MFC (Microsoft Foundation Class) by means Visual Studio 2005, that implements an interface to facilitate the use of UPEN (Uniform PENalty) and its related input files. It is composed by a simple SDI (Single Document Interface) window with many dialog boxes. By means of the dialogs the user can pre-process the data file using the appropriate program filter, sets the value for the parameters, both for UPEN and programs filter, and runs a computation session. Parameters can be set also in the initial parameter file, by clicking the “par” menu button and proceeding to the desired parameter file (such as Upenpar.par), making any needed changes, and saving or not saving as desired. UPEN is an executable (binary format) for Windows platform, developed in True Basic, that implements a new robust algorithm for the inversion of multiexponential decay data. The name refers to the application of negative feedback to a smoothing “penalty” function to prevent excessive detail in distributions of relaxation times. This allows appropriate smoothing of both sharp peaks and broad features in the same distribution, allowing the sharp peaks without breaking broad features into multiple peaks not required by the data. This allows meaningful computation of the rms noise and supports additional UPEN objectives, which include identifying various data features and data problems (such as data not precisely fitting the model of multiexponential decay plus random noise), giving a series of diagnostics and warnings and allowing processing options where needed. There are many adjustable parameters in UPEN, most of which need not and should not be adjusted except in specialized circumstances or in basic investigation of UPEN function. The input data file for UPEN is a binary file produced by any of several preprocessing “Filters”. UPEN is an iterative inversion computation, and the evolving distributions and various computed quantities are shown at each iteration. When computation is complete, two text files are produced. A file with the extension .tst lists a number of computed parameters, including some diagnostic quantities. A file with the extension .dat lists the computed distributions in several forms and also lists the data.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
