Classification overall

Tilia with Amended Classification Overall Results... [Pg.216]

The products could be classified as a function of various criteria physical properties (in particular, volatility), the way they are created (primary distillation or conversion). Nevertheless, the classification most relevant to this discussion is linked to the end product use LPG, premium gasoline, kerosene and diesel oil, medium and heavy fuels, specialty products like solvents, lubricants, and asphalts. Indeed, the product specifications are generally related to the end use. Traditionally, they have to do with specific properties octane number for premium gasoline, cetane number for diesel oil as well as overall physical properties such as density, distillation curves and viscosity. [Pg.483]

The reasoning behind the first change is that NDE made for Class should be a sample of the QC programme rather than a separate exercise. In this way the original purpose of the Classification checkpoints is restored and the overall quality level of welding can be monitored. [Pg.1042]

During the construction of a ship the Surveyor monitors NDE results for completeness of testing and overall quality of welding. This role includes the evaluation of checkpoints taken specifically for classification purposes but also includes the monitoring of additional checkpoints taken for quality control purposes by the builder. In the case of tankers built to LR Class since 1994 and for bulk carriers built to Class since January 1996 the Surveyor will witness the actions listed as part of the ShipRight Construction Monitoring procedure that is now mandatory. [Pg.1045]

Schemes for classifying surfactants are based upon physical properties or upon functionality. Charge is tire most prevalent physical property used in classifying surfactants. Surfactants are charged or uncharged, ionic or nonionic. Charged surfactants are furtlier classified as to whetlier tire amphipatliic portion is anionic, cationic or zwitterionic. Anotlier physical classification scheme is based upon overall size and molecular weight. Copolymeric nonionic surfactants may reach sizes corresponding to 10 000-20 000 Daltons. Physical state is anotlier important physical property, as surfactants may be obtained as crystalline solids, amoriDhous pastes or liquids under standard conditions. The number of tailgroups in a surfactant has recently become an important parameter. Many surfactants have eitlier one or two hydrocarbon tailgroups, and recent advances in surfactant science include even more complex assemblies [7, 8 and 9].

The predictive power of the CPG neural network was tested with Icavc-one-out cross-validation. The overall percentage of correct classifications was low, with only 33% correct classifications, so it is clear that there are some major problems regarding the predictive power of this model. First of all one has to remember that the data set is extremely small with only 11 5 compounds, and has a extremely high number of classes with nine different MOAs into which compounds have to be classified. The second task is to compare the cross-validated classifications of each MOA with the impression we already had from looking at the output layers. [Pg.511]

It is quite common ia the designs for fine classification to recontact the coarse stream transversely or ia counterflow with air before dischargiag it (see Fig. 9). This removes dry fine particles not removed ia the primary classification. That is, these particles are swept back iato the feed and given another chance to exit with the fine particles. Such an arrangement iacreases the overall sharpness iadex and reduces the overall apparent bypass. Another variation is to reenter the air from the sohd/gas separation of the coarse stream. [Pg.441]

Another classification of detector is the bulk-property detector, one that measures a change in some overall property of the system of mobile phase plus sample. The most commonly used bulk-property detector is the refractive-index (RI) detector. The RI detector, the closest thing to a universal detector in lc, monitors the difference between the refractive index of the effluent from the column and pure solvent. These detectors are not very good for detection of materials at low concentrations. Moreover, they are sensitive to fluctuations in temperature. [Pg.110]

On the macroscopic scale, two coal classifications have been used humic or banded coals and sapropeflc or nonbanded coals. Stratification in the banded coals, which result from plant parts, is quite obvious the nonbanded coals, which derive from algal materials and spores, are much more uniform. The physical and chemical properties of the different layers in a piece of coal or a seam can vary significantly. Therefore the relative amounts of the layers are important in determining the overall characteristics of the mined product. Coal petrography has been widely appHed in cokemaking and is important in coal hquefaction programs. [Pg.213]

The basic nature of composite materials was introduced in Chapter 1. An overall classification scheme was presented, and the mechanical behavior aspects of composite materials that differ from those of conventional materials were described in a qualitative fashion. The book was then restricted to laminated fiber-reinforced composite mafeffals. The basic definitions and how such materials are made were then treated. Finally, the current and potential advantages of composite materials were discussed along with some case histories that clearly reveal how composite materials are used in structures. [Pg.332]

If the pumps are located indoors, a Division 1 classification is likely to apply. Motors must be Class 1, group D, explosion-proof, or they may be separately ventilated with clean outside air brought to the motor by fans. Auxiliary devices such as alarm contacts on the motor must be suitable for the area classification. The installed costs, overall efficiencies, and service factors associated with the enclosures that are available will influence the selection. [Pg.416]

Overall, the effectiveness of electronic configurations in the classification of spectral lines is surprising as expressed by Jorgensen [1971]. [Pg.28]

There is an extremely wide range of potentially useful chemical treatments available, and for any boiler system, proper selection, utilization, and control are vital considerations that may largely determine the ultimate success of the overall program. These chemicals usually are organized by type of compound, function, mode of action, or similar classification, but, because many chemicals are multifunctional in character, may be used in either a primary or supplementary (adjunct or conjunctional treatment) role, and additionally may be branded (especially many modem polymers) or otherwise disguised, such classifications may be quite arbitrary. [Pg.385]

The sub-classification of the oxidising metal ions derives from overall reactivity, which is only crudely related to redox potential and is gauged largely with hindsight. [Pg.276]

It should be noted that the decomposition shown in Eq. 3.7.2 is not necessarily a subdivision of separate sets of spins, as all spins in general are subject to both relaxation and diffusion. Rather, it is a classification of different components of the overall decay according to their time constant. In particular cases, the spectrum of amplitudes an represents the populations of a set of pore types, each encoded with a modulation determined by its internal gradient. However, in the case of stronger encoding, the initial magnetization distribution within a single pore type may contain multiple modes (j)n. In this case the interpretation could become more complex [49]. [Pg.344]

The long-term widespread use of DDT over a number of years demonstrates one typical Soviet trick - abusing loopholes in the rules. DDT was actively used for decades, while not being on lists of permitted substances, a situation condoned by the Health and Epidemiological Services and their on-site agencies. Pesticide use systematically was not in accordance with the permissible standards in the USSR. In 1976 the USSR introduced a System of Labor Safety Standards Harmful Substances, Classification and Overall Safety Requirements, according to which all harmful substances were broken down into four risk classes, taking into account several different indices (table 1.5). [Pg.18]

It does little good to continue to find a difference in overall response levels between normals and schizophrenics in our electrophysiological, positron emission, biochemical, and behavioural measures unless we use the knowledge to lead to new approaches to classification, treatment and etiology. [Pg.164]

When crystals are imperfectly formed, or if the relationship between the faces cannot be discerned, it is still useful to provide a more empirical judgement regarding the overall shape of the particles. A classification scheme, similar to that provided by Amidon [8], is proposed in Table 2. Solids illustrating these definitions are provided in Fig. 1. [Pg.130]
