Software activity steps, application

One major advantage of the PMod software is the graphical interface that allows the interactive configuration of the kinetic model by the user as well as the application of some preprocessing steps, e g. setting up initial values and limits for the fit parameters. Visual evaluation of each plot is performed to check the quality of each fit. Each model curve is compared with the corresponding time-activity curve and the total X2 difference was used as the cost function, where the criterion was to minimise the summed squares (X2) of the differences between the measured and the model curve. The distribution at each individual point is taken to be Gaussian, with a standard deviation to be specified. The model parameters are usually accepted when kl-k4 is less than one and the vb value exceeds zero. The unit for the rate constants kl-k4 is 1/min, while vb reflects the fraction of blood within the evaluated volume. 

Afterward, the structure of the design projects is analyzed to identify recurring routine activities they are made available in the form of reference process components. Initially, this is done separately for both application partners. In a second step, similarities between the two application partners are identified. The validity and integrity of the collected parameters is increased through this process. In order to represent the design projects created in the first step, including influencing variables and process parameters, an appropriate software environment is identified. 

Public key cryptography is fast becoming the foundation for on-line commerce and other applications that require security and authentication. The use of this kind of cryptography requires a public key infrastructure (PKI) to publish and manage public key values. To prepare the activities for the implementation of PKI features an evaluation of commercial hardware and software solutions is necessary. The implementation of PKI features generally can be divided into several steps ...
