Spreadsheets structure

Spreadsheet Structure There are three principal sections to the spreadsheet. The first has tables of as-reported and normalized composition measurements. The second section has tables for overall and component flows. These are used to check the overall and component material balance constraints. The third has adjusted stream and component flows. Space is provided for recording the basis of the adjustments. The structure changes as the breadth and depth of the analysis increases. 

While it is usefiil to know the atomic numbers of some of the more commonly encountered elements, no one expects to comfortably carry all of these in his head. The spreadsheet structure makes this unnecessary. Let us use the feature known as Block Names. By this means, we can devise some useful and easily recognized symbol to describe a block of one or more cells that, when written, will represent the contents of that cell(s). We have a natural candidate for the suitable symbol in this case - the symbol for the element in question ... 

Output data can be printed or exported to a spreadsheet. The rendering quality is very good. Structures can be rendered and labeled in several different ways. Molecular structures can be saved in several different formats or as image files. The presentation mode allows molecular structures to be combined with text. 

The box marked C ellfor example, represents the idea that a spreadsheet has a number of addressable units that can be displayed. It doesn t say how they get displayed, and it doesn t say that if you look inside the program code you ll necessarily find a class called C elllf the designer is interested in performance, some other internal structure might be thought more efficient. On the other hand, if the designer is interested in maintainability, using a structure that follows this model would be helpful to whoever will do the updates. 

The application architecture A package structure and collaborations. This implements the business logic itself as a collection of collaborating components, with the original specification types now split across different components. The components can range from custom-built to common off-the shelf components, such as spreadsheets, calendars, and contact managers, to purchased domain-specific components such as factory-floor schedulers. This application architecture lives atop, and uses, the technical architecture. 

The spreadsheet in Figure 4-62 is heavily matrix based (see Chapter 2, for an introduction to basic matrix functions in Excel). It is the only way to keep the structure reasonably simple. The matrix C in cells A21 C31 is computed in the usual way, see equation (4.63) the parameters required to compute the concentration matrix are in cells Q4 S4, they include the initial concentration for species A and the two rate constants that are to be fitted. In cells E 16 018 the computation of the best absorptivity matrix A for any given concentration matrix C, is done as a matrix equation, as demonstrated in The Pseudo-Inverse in Excel (p.146). Similarly the matrix Ycaic in cells E21 031 is written as the matrix product CA. Even the calculation of the square sum of the residuals in cell R7 is written in a compact way, using the Excel function SUMXMY2, especially designed for this purpose. We refer to... 

Peterson has presented a Bayesian approach to defining the DS, which provides design space reliability as well, as it takes into account both model parameter uncertainty and the correlation structure of data. To aid in use of this approach, he proposes a means of organizing information about the process in a sortable spreadsheet, which can be used by manufacturing engineers to aid them in making informed process changes as needed, and continue to operate in the DS. 

In order to evaluate results obtained from different calculation runs, a number of standardized reports were integrated into the decision support tool. The reports can be clustered into the three categories production network structure, cost structure and investment/restructuring activities (cf. Fig. 49). Since reports become very complex if they contain data from several scenarios, comparative analyses of different scenarios are performed via data downloads into MS Excel pivot spreadsheets. 

A spreadsheet is opened with all structures ranked in a column. Select all rows with conformations and add energy scores ... 

The Cournot model is a standard oligopoly model, and it is often used in competition policy as a first approximation of how competition works (Martin, 1993). For our modelling purposes, the Cournot oligopoly model offered the best combination - faithful representation of market cost structure and behaviour, and flexibility to incorporate a mixture of profit-maximizing and sales-maximizing objectives - as well as tractable conversion into a spreadsheet modelling application. 

Both mass transfer resistances are interconnected in a rather complex manner. The structure of these interconnections was made visible by the presentation of analytical solutions which could be easily handled on a spreadsheet calculation tool, even for much more complicated VLE equations with variable relative volatilities and chemical equilibrium equations of any complexity because no integration procedure is necessary, but just finding roots.
