Testing the Systems Framework

The systems of such type have been developed of all last 10 years. We shall bring some characteristics of one of the last development within the framework of European BRITE project, carried out in LETT This 3D cone-beam tomograph is referred to as EVA Bench or Equipment for Voludensimetry Analysis. It is oriented on NDT of industrial products from ceramics and other composites. One of the main task of this tomograph is achievement of high resolution at study of whole internal volume of researched object. For test sample of the size 10mm spatial resolution in 50mm was obtained [14]. 

From the Model of Modelling framework and knowledge of stndents difficulties in learning chemical eqnilibrinm, we developed a modelling-based teaching sequence for this theme (Ferreira Jnsti, 2005). The seqnence provides students with opportuiuties to bnild, test and rebnild models in order to explain the occurrence of a given chemical reaction, the reversibility of that chemical reaction, the establishment of a chemical eqnilibrium in the system under stndy and the behavionr of the system when the eqnilibrinm is changed. The stndents were not directly introduced... 

Documentation is structured around specifications and implementation and their refinement and import relationships. A user manual—a description of how a user accomplishes tasks by using the system(s)—is a particular form of documentation associated with a refinement how the abstract business model and actions are realized by more-detailed actions performed by the users and systems. Test specifications are also associated with refinement relationships. The rules for system architecture are documented in a package that specifies the patterns and frameworks that will be used in other packages that import it. 

Functional Requirements The high-level user requirements establish the framework for the functional specifications which identify the system functions, mode of operation, and operation environment necessary to meet the user requirements. Again, the requirements should be verifiable or testable to demonstrate that the requirements can be met during the qualification testing. 

The cation plays a prominent structure-directing role in zeolite crystallization. The unique structural characteristics of zeolite frameworks containing polyhedral cages (62, 63) have led to the postulate that the cation stabilizes the formation of structural subunits which are the precursors or nucleating species in crystallization. The many zeolite compositions and complex cation base systems studied allow a test of the structuredirecting role of the cation and the cation templating concept. Table I summarizes the cation base systems from which zeolites have been synthesized. The systems used before 1969 are indicated to illustrate the number and complexities of new cation systems investigated since that time. Table II presents a summary of zeolite framework structure types, the cation systems in which they have been formed, and a proposal for a cation specificity for the formation of each framework type. A similar...

One case study within the framework of this project is thus to test the concept of a micro structured reactor plant by applying the fast reaction of the enantioselective synthesis via organoboranes yielding chiral-substituted alcohols. This is typically a batch process carried out in the laboratory using conventional glassware and in the present case has been converted into a continuous process carried out by micro structured devices. This set-up has been used to characterize the physical properties of the backbone system. 

The most-tested hydrophobic zeolite in adsorption of organic compounds from water solutions is silicalite-1 [89], This material is a molecular sieve with an MFI structure composed of pure silica. The MFI framework has a 10-MR channel system with elliptical pores having diameters of 5.2 x 5.7 A [83], Additionally, other zeolites, as the all-silica P-zeolite [216] which possesses a three-dimensional, 12-numbered ring, interconnected channel system with pore diameters of 7.1 x 7.3 A [83] have been used in the elimination of methyl tert-butyl ether (MTBE) from water solutions [88],... 

Quantitative chromium solid-state speciation in chromite ore processing residue (COPR) has defined the mineral species and the processes controlling the retention and release of Cr(VI) from CO PR-contaminated sites (Hillier et al, 2003). Information that, used within a process-based modelling framework, has helped to predict the impact of changes in physicochemical conditions on the COPR, to test the extent to which the system may be considered at equilibrium and that, therefore, need to be considered within the context of informed remediation (Geelhoed et al, 2001).
