At the present time the only online facility that we provide for analyzing the data is the display function, which provides graphical outputs tailored to the data in the diffraction data files. The user specifies the run number for the data he wishes to plot. The display program then loads the header from the appropriate data file and determines what kind of plot to display. The user can dump the resulting plot to the printer to provide a record of his experiment. The "revise file" function can be used to create auxiliary files for plotting selected features of the data. [Pg.150]

Selected Features of the Chemistry of N,N-Bis-Trimethylsiloxy-Substi-tuted Cyclopropanes and Dihydrofurans Scheme 3.217 shows selected features of the chemistry of compounds prepared by intramolecular trapping of bis-N,N-(trimethylsiloxy)iminium cations. [Pg.645]

It has also been shown that the selectivity features of para-selective catalysts can be readily understood from an interplay of catalytic reaction with mass transfer. This interaction is described by classical diffusion-reaction equations. Two catalyst properties, diffusion time and intrinsic activity, are sufficient to characterize the shape selectivity of a catalyst, both its primary product distribution and products at higher degrees of conversion. In the correlative model, the diffusion time used is that for o-xylene adsorption at... [Pg.299]

Closely related to the creation of regression models by OLS is the problem of variable selection (feature selection). This topic is therefore presented in Section 4.5, although variable selection is also highly relevant for other regression methods and for classification. [Pg.119]

One disadvantage of an autofocus camera is that the camera does not always focus on the desired object. If the object of interest to the photographer is in the backgroimd and another object is in the foreground, then the camera may select and focus on the closer object. A familiar example is the out-of-focus picture where the camera has focused on some backgroimd object in the gap between two people. Most autofocus cameras are now equipped with a selectable feature to overcome this limitation. [Pg.362]

Using the information in table 1.4, the used-car ad can be divided into five moves. In the first move (included in all six ads), the seller states the essential facts about the car (year, make, and model). In the second move (included in all but two ads), the seller highlights select features of the car (e.g., new tires, air bags, five speeds). In the third move (interchangeable with the second), the writer offers a subjective description of the car (e.g., good cond or fun ). In the fourth move, the writer states the price. Finally, in the fifth move, the seller provides contact information (1) a phone number, (2) a contact name (optional), and (3) when to call (optional). [Pg.16]

A block diagram of our pattern recognition GA is shown in Fig. 3. Selected feature subsets are coded as binary strings called chromosomes. Each chromosome describes a unique set of features. A particular feature is present in a chromosome or binary string if the corresponding bit in the string is set to 1. The length of each chromosome is equal to the number of features in the data... [Pg.415]

The steady-state luminescence spectra of three different plastics are characterized by blue luminescence with Amax = 445-465 nm, while much broader liuninescence band with yellow color characterizes the dolomite rocks. These spectra are different, but not enough to differentiate between them from big distance. The decay properties have been also checked in order to improve the selective feature. It was found that luminescence intensity of rocks in the blue part of the spectrum is drastically diminished after specific delay time, while the decrease of intensity in the yellow part of the spectrum is mush more moderate. Liuninescence intensity of all plastics also diminishes after such delay, nevertheless remaining mush stronger then intensity of rocks luminescence in the blue part of the spectrum. The comparison of plastic and rock time-resolved spectra in specific time window clearly demonstrate that they are absolutely different, which made confident discrimination possible (Fig. 7.3). [Pg.275]

All these methods use selective features, which are not directly connected with gold contents. [Pg.311]

In this case, the multicollinearity problem can be avoided by feature selection (e.g., by a decorrelation procedure, subtraction or eigenvector projection) followed by BA in the space of selected features. [Pg.120]

The desire for a sustainable development in chemistry lays the foundation for environmentally benign processes. From the view point of organic chemistry, the construction of carbon skeletons plays the pivotal role. The extraordinarily mild reaction conditions in addition to the non-toxic and non-bumable properties and ubiquitous availability of water as the reaction medium make enzyme-catalyzed C-C-bond formation the first choice even for industrial production. Thanks to subtle selectivity features of the corresponding enzymes a rather broad range in substrate specificity meets with a highly conserved stereospecificity at the newly connected carbon centers. In addition, these features and the availability of the respective biocatalysts are open to intervention by recombinant genetechnological techniques. [Pg.210]

Such chiral selection features of self-organized entities are of general significance in connection with the questions of spontaneous resolution and of chirality amplification. They amount to a self-re solution process. [Pg.171]

Because of the high reactivity of the [(arene)FeCp]+ complexes, it can be expected that further developments and definition of selectivity features will be forthcoming. [Pg.542]

The application of this concept to liquid samples is what we already refer to electronic tongue . It entails the use of multidimensional information coming from an array of chemical sensors, mimicking the animal sense of taste. As several possibilities exist on the side of which sensors form the array, the general response shown by the different sensors used is of paramount importance that is, cross-selectivity features are needed in order to profit from the multidimensional aspects of the information [7]. The performance of electronic tongues can be suited not only to qualitative purposes like identification of species and classification of sample varieties, but also to quantitative uses, normally the multidetermination of a set of chemical species, an interesting objective for process control. A more bioinspired trend is the artificial taste [8] in order to perform automated taste perception, especially in the industrial field. [Pg.722]
