Conflicting Requirements

Safety is essential for all pressure vessels, but ideally NGV containers should also be lightweight and inexpensive, with the highest possible capacity for a specified external envelope. In a given application, some degree of compromise is unavoidable between these conflicting requirements. 

The standard requires that incomplete, ambiguous, or conflicting requirements be resolved with those responsible for drawing up these requirements. 

At this point it might be appropriate to comment on the conflicting requirements of the synthesis. The large interest which other conjugated polymers such as polypyrrole, polyanilinc or poly(parattracted originates, firstly, from their attractive physical properties, but also from the sim-... 

Whether elegantly simple (e.g., the use of canaries as detectors) or technologically complex, a reliable detection system must attempt to address several, sometimes conflicting requirements. Trade-offs between size/weight/power... 

In the case of ventilation consideration of energy conservation must be taken into account. Some work in recent years, however, indicate that the conflicting requirements of energy conservation by means of making dwellings more airtight and increased ventilation for radon reduction may be accomodated by the use of heat exchangers... 

In any docking scheme, two conflicting requirements must be balanced (i) the desire for a robust and accurate procedure and (ii) reasonable run time of the laboratory workstation for the computational method chosen. 

The subtype conforms to all the expectations that any client could have based solely on the guarantees of both supertypes. Further requirements particular to this subtype may be added. It s perfectly possible to combine two types that have conflicting requirements so that it would not be possible to implement the result. 

The discovery that several controlling factors in decay of polysaccharide -plastic composites are physico-chemical in nature (rather than environmental or biological) should make it possible to develop an accurate simulation model to define structural and biodegradable boundaries to achieve the best balance between the two conflicting requirements. This type of model would facilitate development of materials that are satisfactory by both engineering and biodegradability criteria a model of this type is currently being developed in my laboratory. 

The SOPs on software change control and data change control must be written in a coordinated fashion to avoid conflicting requirements. 

Linkers are molecules which keep the intermediates in solid-phase synthesis bound to the support. Linkers should enable the easy attachment of the starting material to the support, be stable under a broad variety of reaction conditions, and yet enable selective cleavage at the end of a synthesis without damage to the product. Several types of linker have been developed, which meet these conflicting requirements to different extents [1]. Newer developments include linkers containing fluorine to facilitate the monitoring of solid-phase chemistry by NMR (see Section 1.3.5), and enantio-merically pure linkers that enable the synthesis on solid phase of enantiomerically enriched products [2],... 

The conflicting requirements of high activity for HDS and high capacity for metals accumulation for long life suggest that an optimum in catalyst... 

A schematic diagram of a sensor based on a thermistor is shown in Fig. 3.2. Because of their sensitivity, thermistors are preferred over thermocouples however, any type of thermometer can be used in such design. There are some conflicting requirements... 

Through an agreement in Vienna in 1991, CEN and ISO have cooperated in the following way. Since both technical committees targeted standardization of cleanroom specifications they were merged to form the committee ISO/TC 209, Cleanrooms and Associated Controlled Environments. Draft standards are submitted to ISO and CEN bodies at the same time. If approved by CEN, the standard will become a mandatory national standard of all the European states and existing conflicting requirements have to be withdrawn. If approved by ISO, the member states (outside Europe) can adopt the standard if they want to do so. 

In any finite field calculation, the choice of F is important because of the conflicting requirements of a small Fto make truncation valid and a large Fto minimize the rounding errors in the differences. The optimum choice clearly depends on the relative values of K0), a, / , etc. for the molecule concerned. 

The aim of process design is to build the best overall plant, all units within the designed plant may not operate at maximum efficiency or full potential. It is necessary to achieve a balance between the conflicting requirements of the individual units to produce the best plant possible. Plant design is an exercise in compromise and optimization.
