Data analysis module

The Data Analysis module of FDS facilitates the interactive analysis of constant pressure and constant flow filtration, jar sedimentation and piston press (expression) tests the procedures are computer software implementations of the analysis techniques described in Chapter 4. Data obtained at the laboratory, pilot and even full scale can be analysed in a consistent manner 

Using a laboratory centrifuge with an acceleration of about 1000 g, and various spinning times, determine the consistency of the settled solids (firm paste, flowable, etc.) and the time taken for the solids to settle and the supernatant liquid to clear. These tests are helpful, but not necessarily essential. 

Requires the particles to be small and charged a measure of the leta potential is helpful. Assessing the potential of electrical assistance is relatively difficult and requires speciaiist apparatus.

The data analysis module of ELECTRAS is twofold. One part was designed for general statistical data analysis of numerical data. The second part offers a module For analyzing chemical data. The difference between the two modules is that the module for mere statistics applies the stati.stical methods or rieural networks directly to the input data while the module for chemical data analysis also contains methods for the calculation ol descriptors for chemical structures (cl. Chapter 8) Descriptors, and thus structure codes, are calculated for the input structures and then the statistical methods and neural networks can be applied to the codes. 

The data analysis module facilitates interactive analysis of leaf filtration, jar sedimentation and piston press test data. Calculations are performed in a hierarchical manner using the available information if some data are not measured then FDS performs the best possible analysis using approximations. The results of an analysis can be used to refine (shorten) a list of selected equipment and/or provide scale-up information for equipment simulation.

At the end of the infield inspection, the Data Acquisition Module exports all data in the form of text files that can be read and processed by the Data Analysis Module. 

Data Analysis Module form-office review... 

The Data Analysis Module concludes the last part of the inspection process. Once infield data acquisition phase is completed, in the office the Data Analysis Module allows the inspection team to review the checklists and, supported by the video, to fill missed information or to correct errors before drawing up the inspection report. 

Data input for both modules can be done via file upload, whereby the module for mere statistics reads in plain ASCI I files and the module For chemical data analysis takes the chemical structures in the Form of SD-files (cf. Chapter 2) as an input. In... 

An additional feature of ELECTRAS is a module which provides an introduction to various data analysis techniques One part of this module provides a typical work flow for data analysis. It explains the important steps when conducting a data analysis and describes the output of the data analysis methods. The second part gives a description of the methods offered. This modvJe can be used both as a guideline for novice users and as a reference for experts. 

RISKMAN is an integrated Microsoft Windows , personal computer software system for [H. i forming quantitative risk analysis. Used for PSAs for aerospace, nuclear power, and chemical [iroccsses, it has five main modules Data Analysis, Systems Analysis, External Events Analysis, Event Tree Analysis, and Important Sequences. There are also modules for software system maintenance, backup, restoration, software updates, printer font, and page control. PEG has also integrated the fault tree programs CAFTA, SETS, NRCCUT, and IRRAS into RISKMAN. 

MARS provides the foundation of data management and reporting on which specialized analysis modules can be built. This represents a more efficient utilization of software resources and facilitates co-reporting and coplotting of results. 

The MARS software is adapted and compiled specifically for a given application. The software is organized into modules which can be interchanged as needed for a particular implementation. Most modules comprise a core of management, analysis, reporting, and plotting functions which are used for every implementation. For each application, a data acquisition module is adapted to suit the appropriate instrumentation. In addition, specialized analysis programming is added if required. The acquisition module, the core modules, and the specialized analysis modules, if any, are then linked into a customized application specific version of MARS. 

First pass analysis—data to modulation depth and phase shift... 

Figure 3.1 Schematic diagram of an AAS spectrometer. A is the light source (hollow cathode lamp), B is the beam chopper (see Fig. 3.2), C is the burner, D the monochromator, E the photomultiplier detector, and F the computer for data analysis. In the single beam instrument, the beam from the lamp is modulated by the beam chopper (to reduce noise) and passes directly through the flame (solid light path). In a double beam instrument the beam chopper is angled and the rear surface reflective, so that part of the beam is passed along the reference beam path (dashed line), and is then recombined with the sample beam by a half-silvered mirror.

The least-squares method is also widely applied to curve fitting in phase-modulation fluorometry the main difference with data analysis in pulse fluorometry is that no deconvolution is required curve fitting is indeed performed in the frequency domain, i.e. directly using the variations of the phase shift and the modulation ratio M as functions of the modulation frequency. Phase data and modulation data can be analyzed separately or simultaneously. In the latter case the reduced chi squared is given by... 

The well-defined statistics in single-photon counting is an advantage for data analysis. In phase fluorometry, the evaluation of the standard deviation of phase shift and modulation ratio may not be easy. 

The mobility of tyrosine in Leu3 enkephalin was examined by Lakowicz and Maliwal/17 ) who used oxygen quenching to measure lifetime-resolved steady-state anisotropies of a series of tyrosine-containing peptides. They measured a phase lifetime of 1.4 ns (30-MHz modulation frequency) without quenching, and they obtained apparent rotational correlation times of 0.18 ns and 0.33 ns, for Tyr1 and the peptide. Their data analysis assumed a simple model in which the decays of the anisotropy due to the overall motion of the peptide and the independent motion of the aromatic residue are single exponentials and these motions are independent of each other.
