Thresholds for declarations

Subject to special thresholds for declaration and verification. CAS, Chemical Abstracts Service. 

Whenever reference is made to groups of dialky lated chemicals, followed by a list of alkyl groups in parentheses, all chemicals possible by all possible combinations of alkyl groups listed in the parentheses are considered as listed in the respective Schedule as long as they are not explicitly exempted. A chemical marked on Schedule 2, part A, is subject to special thresholds for declaration and verification, as specified in Part VII of the Verification Annex.)... 

It is understood that a plant site containing a plant in which a Schedule 2 chemical is consumed in a waste management or disposal system in quantities above the threshold for that chemical will declare this consumption in accordance with Part VII, paragraph 8. 

Recalling further that, in addition, for declared Schedule 2 plant sites, the Convention requires States Parties to provide data on the quantities imported and exported of each Schedule 2 chemical produced, processed, or consumed above the declaration threshold at the declared plant site under the provisions of paragraphs 8(b) and 8(c) of Part VII of the Verification Annex ... 

The availablility of an estimate of the conditional cdf F CzjCN)) at each nodal joint x allows an assessment of the risks a(x) or p(x) of making wrong decisions. Consider the contour map of a particular estimate p (x), x (see Figure 3a). Suppose that the threshold value 500 has been selected to declare any sub-area of A hazardous. The contour line 500 on Figure 3 delineates the zones which are candidates for cleaning. Within these zones, the probability that the concentration is actually under 500, i.e. the risk a(x) of cleaning unduly, can also be mapped ... 

The value applied to each mass is derived from the value of the associated residual. In a boolean framework, a threshold would be defined such that some values are declared as fault-free i.e., when the residual is lower than the threshold) and other ones as faulty i.e., when the residual is higher than the threshold). This method produces for each situation a vector of 0 and 1 that can be compared to the known signatures to isolate the fault. As already pointed out one main drawback is that if the value of the residual oscillates around the threshold, the state associated to the residual oscillates too. On the contrary, in the Evidence theory framework, an infinity of values are possible for each focal element. It is then possible to use smooth functions to produce a bba from the residual. For example, the following function has been proposed in [23] ... 

The CWC s other declaration requirements pertained to the numerous chemicals used in ordinary commercial products - fertilisers, pesticides, flame retardants and pharmaceuticals - that also could be diverted to manufacturing poison gas.11 Chemicals that industry used widely for commercial products were listed in Schedule 3,12 and the chemical industry was required to declare its activities with controlled chemicals above certain threshold quantities. However, the CWC was not restricted to compounds that were explicitly listed in the schedules. The discovery of a new potential chemical warfare agent would not, therefore, undermine the CWC because such an agent would be automatically banned if it had no justifiable non-military purpose. 

In most industrial countries and those at the threshold of industrialization, the field of explosion protection for electrical apparatus and systems is subject to legislation. The usual procedure, that a manufacturer declares the conformity of a product with a given standard under his own responsibility, is altered in such a way that an administrative body nominated by the government of a state, or, in states with a federal structure, nominated by the authority of a land, issues an approval which declares the compliance with a standard and with legislative acts in parallel. On this basis, the apparatus may be commissioned and put into service. 

Declarations are required for the production, processing and consumption of Schedule 2 chemicals and for the facilities engaged in such activities in excess of certain thresholds. Declarations are also required with respect to the production of Schedule 3 chemicals and for facilities engaged in such production in excess of certain thresholds, as well as for OCPFs. ... 

Key concerns about use of name as the primary means of identification of an individual is that it can have many variations that are difficult to be computationally analyzed so as to declare that two or more records belong to the same individual. Fuzzy logic can be used for searching to increase the matching threshold. 

The decision limit (CCa) is defined in point 1.11 of the Annex to Commission Decision 2002/657/EC. The decision limit (CCa) means the limit at and above which it can be concluded with an error probability of a that a sample is non-compliant. During a screening process, a substance detected above the CCP must be declared suspect (or screening non-compliant). In some laboratories, the CCa is used as a threshold to establish the suspicion, especially for forbidden substances. During a confirmatory process, a substance detected above the CCa must be declared non-compliant, on the condition that the appropriate identification criteria are fulfilled, for example, using the identification point system described in Commission Decision 2002/657/EC and CAC/GL 71-2009. ... 

Since the user will never be totally satisfied with automatic analysis all the time, it is very important to allow him to assume control over all parts of the quantification whenever necessary. For example, the peak analysis routine of FSUNMR performs an automatic quantification by default. The user is given a wide range of options when the computations are complete. These include insertion and deletion of peaks, manual declaration of a threshold, peak position calibration, and a complete set of display options. Good peak analysis routines can save the spectroscopist a lot of time without...
