Attribute dimension

Inspection of the fabric attribute dimensions for all location points revealed that certain attributes were either absent or unrecognizable. These attributes are fiber bundle, fiber single, fiber crimp, fiber surface, fiber pattern, yarn type, and yarn twist direction. Therefore, these attributes were deleted from the statistical analysis. The remaining attributes were either present at all location points or exhibited variation. These attributes included the three (layers, 1/1, and float) whose interactive effects had direct relevance to the research hypothesis, and the following fiber and yarn attributes paired fibers, 0 twist, combined yarns, yarn system A, yarn systems A + B, yarn systems A + B + C + D, fabric distortion, red, green, and black. 

The incidence of float and float with 1/1 interworking occurred in the L-Q area of the x axis and between 4.9 and 7.7 on the y axis. Two adjacent points [(N.2, 6.2) and (N.2, 6.3)] differ in the interworking attribute dimension. The point (N.2, 6.2) is classified as float only and (N.2, 6.3) is classified as float plus 1/1 interworking. All of the micrographs displaying float were in the area where at least the main layer had a similar orientation across the blade. This area also had raised pseudomorphs after fabric that suggested a crumpled fabric. 

Attribute dimensions need to be more clearly defined and linked more closely to the initial survey in order to focus upon variation. 

Standards have been a part of technology since building began, both at a scale that exceeded the capabiUties of an individual, and for a market other than the immediate family. Standardization minimizes disadvantageous diversity, assures acceptabiUty of products, and faciUtates technical communication. There are many attributes of materials that are subject to standardization, eg, composition, physical properties, dimensions, finish, and processing. Implicit to the realization of standards is the availabiUty of test methods and appropriate caUbration techniques. Apart from physical or artifactual standards, written or paper standards also must be considered, ie, their generation, promulgation, and interrelationships. 

Product standards may stipulate performance characteristics, dimensions, quaUty factors, methods of measurement, and tolerances and safety, health, and environmental protection specifications. These are introduced principally to provide for interchangeabiUty and reduction of variety. The latter procedure is referred to as rationalization of the product offering, ie, designation of sizes, ratings, etc, for the attribute range covered and the steps within the range. The designated steps may foUow a modular format or a preferred number sequence. 

One of the origins of this view of error and accident causation is the theory of accident proneness, which tried to show that a small number of individuals were responsible for the majority of accidents. Despite a number of studies that have shown that there is little statistical evidence for this idea (see, e.g., Shaw and Sichel, 1971) the belief remains, particularly in traditional industries, that a relatively small number of individuals accoimt for the majority of accidents. Another element in the emphasis on individual responsibility has been the legal dimension in many major accident investigations, which has often been concerned with attributing blame to individuals from the point of view of determining compensation, rather than in identifying the possible system causes of error. 

This deceleratory reaction obeyed the parabolic law [eqn. (10)] attributed to diffusion control in one dimension, normal to the main crystal face. E and A values (92—145 kJ mole-1 and 109—10,s s-1, respectively) for reaction at 490—520 K varied significantly with prevailing water vapour pressure and a plot of rate coefficient against PH2o (most unusually) showed a double minimum. These workers [1269] also studied the decomposition of Pb2Cl2C03 at 565—615 K, which also obeyed the parabolic law at 565 K in nitrogen but at higher temperatures obeyed the Jander equation [eqn. (14)]. Values of E and A systematically increased... 

The fact that brookite also was found experimentally to have the symmetry of F 5 and to have 8 TiO in the unit suggests strongly that our second structure is to be attributed to this crystal. There is also approximate agreement (within 7%) in the dimensions of the unit. It... 

Some of the results are collected in Table 35.7. Table 35.7a shows that some sensory attributes can be fitted rather well by the RRR model, especially yellow and green (/ == 0.75), whereas for instance brown and syrup do much worse R 0.40). These fits are based on the first two PCs of the least-squares fit (Y. The PCA on the OLS predictions showed the 2-dimensional approximation to be very good, accounting for 99.2% of the total variation of Y. The table shows the PC weights of the (fitted) sensory variables. Particularly the attributes brown , and to a lesser extent syrup , stand out as being different and being the main contributors to the second dimension. 

Figure 38.12 shows the position of the twelve meat patties in the space of the first two PLS dimensions. Such plots reveal the similarity of certain products (e.g. C and D, or E and G) or the extreme position of some products (e.g. A or I or L). Figure 38.13 shows the loadings of the instrumental variables on these PLS factors and Fig. 38.14 the loadings of the sensory attributes. The plot of the products in the...
