System perceiving

Written surveys request feedback on the PSM system, asking about its clarity, ease of use, quality of training received on the system, perceived barriers to its effective use, perceived effectiveness in meeting objectives, and suggested modifications and improvements. These kinds of surveys typically mix open-ended and "yes/no" questions, and are distributed to all system users they tend to be simple and brief to encourage participation. Figure 8-6 provides an example. 

Thus, one must expect about 5-10% apparently significant correlations fortunately, these false positives appear in a random arrangement, so that when a really significant connection turns up, the human visual system perceives a clearly recognizable pattern, for example for file PROFILE.dat. (See Fig. 4.28.)... 

Although the actual concentrations of the volatile components in solution remain unchanged after adding the salt, the system perceives a decrease in the concentration of the volatile components. This phenomenon - that the perceived concentration differs from the real concentration - is quite common in the thermodynamics of solution-phase electrochemistry. We say that the concentration persists, but the activity a has decreased by adding the salt. 

The words unit activity here mean that the activity of silver ions is one (so the system perceives the concentration to be 1 moldrrr3). 

For tautomers, the ideal situation is to store one preferred tautomeric form and register other forms as synonyms of this preferred one. However, there is no universally accepted algorithm for tautomer generation, and each registration system will have its own implementation. There will be cases where the system perceives two structures to be tautomers but the chemist knows better and wants to store them separately. Conversely, due to limitations in the tautomer perception algorithm, two tautomeric forms may not be recognised as such. A practical registration system must therefore allow chemists to override the system-provided default. 

There are two key aspects for a well growing plant. One is external factors including environmental conditions and disease resistance methods the other is the integrated immune system of the plant. The plant immune system consists of two interconnected tiers of receptors, one outside and one inside the cell. Both systems perceive the invaders, then inform the whole plant and sometimes the neighboring plants that the intruder is present by an optional signal. The two systems belong to different classes of plant receptor proteins that detect different types of pathogen molecules. ... 

The preceding argument shows that observers in dUfer-ent coordinate systems perceive different accelerations. Mathematically, this is expressed in the following way. First of all, the relationship between the derivative of the position vector r in an inertial reference ftame denoted by subscript 1 and its derivative in a reference frame rotating with angular velocity n relative to the inertial frame is... 

While the traditionalist will seek unsafe acts or unsafe conditions, the systems person will look at what went wrong with the system, perceiving something wrong with the system operation or organization that allowed the mishap to take place. (107)... 

These practical considerations have led investigators away from simple guest-host polymer systems, perceived to have less intrinsic orientation stability, toward systems in which the nonlinear chromophore mobility is hindered. This can be achieved by chemically bounding the active molecules, in side- or in main-chain, or alternatively promoting cross-linking after orientation [17]. 

Data are the mean of 14 panelists. McFlads, multiple-channel flavor delivery system. Perceived intensity at 10 min has been expressed as a percentage of initial intensity (100). 

Stereochemistry. Some systems represent stereochemistry explicitly throughout all levels of Figure 2 some represent it only graphically, or only with text descriptors. Some systems do not treat the stereochemistry of double bonds. Few systems treat noncarbon stereochemistry. Some systems allow structure and substructure searching with stereochemistry in query structures, others do not. Different systems that represent stereochemistry have different ways of handling relative and absolute stereochemistry. No systems perceive the stereochemistry implicit in the biphenyl system 1, although it can be represented graphically. 

Also notable is the unique sweetness response profile of fmctose compared to other sweeteners (3,4). In comparison with dextrose and sucrose, the sweetness of fmctose is more quickly perceived on the tongue, reaches its iatensity peak earlier, and dissipates more rapidly. Thus, the sweetness of fmctose enhances many food flavor systems, eg, fmits, chocolate, and spices such as cinnamon, cloves, and salt. By virtue of its early perception and rapid diminution, fmctose does not have the flavor-maskiag property of other common sugars. 

The perceived color stabiUty of a photographic system is usually limited by the fa ding of its least stable dye, which can produce an undesirable shift in color balance. Whereas recovery of such faded images is often possible, a so-called neutral fade, in which all three color records lose density at approximately the same rate, is usually preferred. 

First, one pump running in a parallel system tends to suffer from cavitation because operation to the right of the BF.P indicates that the NPSHr of the pump rises drastically. To survive this condition, you should use dual mechanical seals on these pumps. Dual or double mechanical seals can withstand cavitation better than a single seal. There is a discussion on this in the mechanical seal chapter of this book. Many engineers perceive that parallel pumps are problematic becau.se they appear to suffer a lot of premature seal failure. Parallel pumps deserve double seals even if it s only a cold water system. 

Third, you would. suppose that parallel pumps are identical, that they were manufactured and assembled together. But it is possible that one pump of the pair is the dominant pump and the other is the runt pump. If you start the dominant pump first in the parallel system, and then decide to add the runt pump of the pair, the weaker pump may not be able to open the check valve. The pump operator perceives that the flow meter on the second pump is stuck or broken. This is because the second pump might be dead heading against a closed check valve, maintained that w ay by the dominant pump. If this situation exists, it may re.sult in premature failure of bearings and. seals, leading maintenance and operations personnel thinking that parallel pumps are problematic. 

Odors are perceived via the olfactory system, which is composed of two organs in the nose the olfactory epithelium, a very small area in the nasal system, and the trigeminal nerve endings, which are much more widely distributed in the nasal cavity (11). The olfactory epithelium is extremely sensitive, and humans often sniff to bring more odorant in contact with this area. The trigeminal nerves initiate protective reflexes, such as sneezing or interruption of irrhalation, with exposure to noxious odorants. 

Subjective evaluation of odor emission is made difficult by the phenomenon of odor fatigue, which means that after persons have been initially subjected to an odor, they lose the ability to perceive the continued presence of low concentrations of that odor. Therefore, all systems of subjective odor evaluation rely on preventing olfactory fatigue by letting the observer breathe odor-free air for a sufficient time prior to breathing the odorous air and evaluating its odor content. Usually an activated charcoal bed is...

The drive for these additional requirements has come not from the suppliers but from users, such as the automotive, utilities, telecommunications, software, and aerospace industries which purchase millions of products and services used to produce the goods and services they provide to the consumer. Rather than invoke customer-specific conditions in each contract, the larger purchasers perceive real benefits from agreeing common quality system requirements for their industry sector. Quite often a supplier will be supplying more than one customer in a particular sector and hence costs increase for both the supplier and the customer if the supplier has to meet different requirements that serve the same objective. All customers desire products and services that consistently/ meet their requirements. While the physical and functional requirements for the product or service will differ, the requirements governing the manner in which their quality is to be achieved, controlled, and assured need not differ. Differences in quality system requirements may arise between industry sectors where the technology, complexity, and risks are different. 

ISO/TS 16949 is not a set of requirements for producing documentation (as many perceive ISO 9000 to be). It contains requirements that address the key characteristics of a quality system which if not met will put product quality (and consequently customer satisfaction) at risk.
