Performance Benchmarking

The ecological risk module allows users to perform benchmark screenings for surface water, sediment, soil, and biota. Accompanying the ecological risk module is a database of benchmarks and other information that are supported and updated on the SADA web site. Benchmarks are adjusted for site-specific physical parameters as appropriate. 

A more general description of the effects of vibronic coupling can be made using the model Hamiltonian developed by Koppel, Domcke and Cederbaum [65], The basic idea is the same as that used in Section III.C, that is to assume a quasidiabatic representation, and to develop a Hamiltonian in this picture. It is a useful model, providing a simple yet accurate analytical expression for the coupled PES manifold, and identifying the modes essential for the non-adiabatic effects. As a result it can be used for comparing how well different dynamics methods perform for non-adiabatic systems. It has, for example, been used to perform benchmark full-dimensional (24-mode) quantum dynamics calculations... 

Normalized metrics can produce ratios that provide better context for comparison across multiple sites, companies, or industry segments. Such metrics can also be useful in one-to-one performance benchmarking. Normalized data provides a rate expression for process safety performance and can be used to compare performance among sites that differ in size and processing technology as well as performance comparisons among companies within an industry or even across industries. There are a number of ways to normalize process safety data, and methods include, but are not limited to ...

In addition to specified validation criteria, it is also useful during method development to assess column durability and column-to-column performance. Benchmarks have been established in a series of papers by Kele and Guiochon for short- and long-term repeatabilities and column-to-column... 

Here E[.] is the expectation operator and e k) and Au(A ) are computed from the data set under examination. The LQG benchmark [115], the historical performance benchmark [222], and the model-based performance benchmark [222, 347] are some of the methods that have been proposed in the literature for CPM of MPC. 

On the basis of the performed benchmark on ammonia, we have extended the study to the first temis of aliphatic amine series, using only the B3LYP/6-311++G computational procedure. The results are collected in Table 12. The theoretical values follow strictly the experimental trend.

In order to provide additional information for the risk assessment, the Committee performed benchmark dose (BMD) modelling using the carcinogenicity data on ochratoxin A from the rat bioassay performed by the NTP (National Toxicology Program, 1989). The occurrence of combined adenomas and carcinomas in the kidneys of the male rats (Table 2), as the most sensitive sex and species for kidney carcinogenicity of ochratoxin A, was considered the most appropriate data for modelling. 

The unfortunate truth is that it is difficult to solve for critical a expressions analytically, even with concrete knowledge of the controllability conditions. Furthermore, repeated higher order derivatives of r bring into question the underlying reliability of the rate expressions themselves (rate functions are typically based on experiment and therefore only valid to within a certain range of accuracy). Nevertheless, these are the conditions for which a critical DSR must abide. It is still valuable to have knowledge of these points, even if they are impractical to achieve in reality, for they serve as targets from which performance benchmarks may be performed. 

Another possibility that arises when the growth path is parameterized is to perform benchmark analyses for example inside the own enterprise between different development sections (although this issue is highly compUcated due to social aspects). The question that always and ever will arise is to determine if differences in processes have a significant effect onto the leUability growth path. Contributing to answering that question is the sense of this paper. 

Benchmarking A search for those best practices that will lead to superior performance. Benchmarking is usually executed with those who perform a targeted activity the best, regardless of the industry they are in. Internal benchmarking makes comparisons within an organization, such as developing best practices from several stores that perform similar functions. 

Kjffir and Sauer ° have reported the construction of new Pople style basis sets for the calculation of NMR spin-spin couplings, 6-31G-J and 6-31IG-J. New basis sets were optimized to the calculation of Fermi-contact (FC) term, and were not expected to provide correctly the values of the remaining contributions (SD, PSO, DSO). The authors performed benchmark calculations of J(C.H). J(N.H), J(N.C), J(C.C), J(O.C), J(O.H), J(H,H), and couplings dominated by the FC contribution, using... 

A third important component of the audit process is the performance indexing of the audit results. The task of performance indexing requires the results of the audit to be quantified in a manner that allows for comparisons against performance benchmarks. While the actual audits may identify the number of unsafe actions performed by personnel during an observation period, the raw numbers are really meaningless until they are placed in a context which is comparable to an established index. The performance indices established from an audit can include the percentages of unsafe acts performed, the frequencies of hazardous conditions identified, or the accident rates for a period of time to name a few.

The criticality detection sensitivity tests conducted in 1968 and 1980 at the LANL Critical Facility have provided important operational performance benchmarks for the Rocky Flats criticality Marm systems. These tests confirm that the response of these systems meet or exceed the performance requirements of ANSI 8.3-1979 and DOE Manual Chapter 0530.
