Rule Objectives

A stub involves a set of code which produces known results. For example, a stub imbedded in ES code could contain "canned" facts rather than executable rules. A stub could be written to determine whether the output from a module is correct. The stub may be as simple as a "canned" temperature value as part of a rule. If the rule path is executing properly, that "canned" temperature value would be returned to the module. Stubs are usually utilized early in the ES software development cycle where linking rules, objects or frames are not available, but pieces or units of ES code are available. Stubs are also occasionally inserted in the integration phase to force a known result or to verify a portion of the knowledge-base. 

A final, yet fundamental point to be made with regard to safety management systems is that their all-encompassing nature often means that safety can easily become cluttered with inspections, rules, objectives and methods for measurement. Yet when we look beyond their titles, within the Health and Safety Executive s safety management guidance, swift prioritisation is made of the ideas of hazard, harm and risk something that often forms only a part of safety management systems. 

In one embodiment, the workflow is structured with predetermined relationships and rules objectively and coherently defined to connect the different fields of elements. The platform containing the interconnected elements can be designed as an open platform allowing external compulations, evaluations, data, and other external influences to be plugged in through, for example, a processor-based system. 

The particularity of each method comes in fact from the "device" object. A "device" is an element of a NDT equipment. The standard aims to define standard "device" objects for the considered 8 NDT methods this is the purpose of chapter 8.3. Nonetheless, the standard draft intends to be open to new teclmiques or to the evolution of conventional techniques, and the possibility is given to define "non-standard devices , under restrictions which are given in the document ("general rules for compliance"). 

Another objective is to discuss briefly recent and major trends in the field of methine dyes color. Indeed, because of its relatively simple structure, the thiazole ring has been chosen in the past for studying color-structure relations. Using Brooker s basicity concepts (5), numerous valuable attempts in different countries succeeded in establishing semiempirical rules for explaining the effects of structural changes on color. 

Heuristic. The heuristic approach is another early synthesis technique based on the appHcation of sets of rules to lead to a specific objective such as network cost. Unfortunately, heuristics caimot guarantee that the objective will be reached although they generally offer quick solutions. 

Using a visible light probe NSOM is the eadiest of the probe scopes, at least in conception, and is another apparent exception to the diffraction-liinited resolution rule, in that NSOM illuminates an object with a beam of visible light smaller than the diffraction limit. The resolution then is limited only by the size of that beam. To achieve this, light issuing from a very tiny aperture at the end of a glass capillary scans a very near sample. The tip must be located on the order of X/2 from that surface. Resolution in the range of 10—20 nm has been achieved (31). 

MultiwaU. shipping sacks are suitable for transport in aU kinds of carriers from tmcks to seafaring vessels. Particular care must be taken to prevent the storage of objects with sharp projections adjacent to the bags in case of doubt, it is advisable to line the enclosure with kraft paper of a basis weight >23 kg. Additional rules for the transportation of multiwaU sacks are contained in appHcable tariff specifications and should be consulted for rail, tmck, and ocean-going shipments. 

The principal objection to -PDA antiozonants is their staining characteristics. The lack of suitable alternative antiozonants for light-colored diene mbber articles is one of the outstanding problems in mbber technology. Pew chemical antiozonants outside the class of -PDAs have much commercial importance. One of the few exceptions to this rule is 6-ethoxy-l,2-dihydro-2,2,4-trimethylquinoline [91-53-2] one of the first commercial antiozonants. 

Supervised Learning. Supervised learning refers to a collection of techniques ia which a priori knowledge about the category membership of a set of samples is used to develop a classification rule. The purpose of the rule is usually to predict the category membership for new samples. Sometimes the objective is simply to test the classification hypothesis by evaluating the performance of the rule on the data set. 

To illustrate the power of the object-oriented style of representation, consider the reactor diagnosis example used eadier in the discussion of rules. Assume that there are several reactors, R-101, R-102, etc, each served by a common cooling system. Relating coolant malfunctions to the temperature in each reactor would need multiple rules, or rules with multiple disjunctions. Instead, if rules are used in combination with the object representation described above, a single general rule can be written to cover all the specific instances, as follows.
