Sequential plan

Thus, a sequential plan is safe, cost-effective in terms of resources and manageable by most organisations. Unfortunately, such a plan has a cost in terms of unacceptable delays to... 

Safety was a concern and a formal rule was implemented (Bolland and Whitehead (2000)) with an overall one-sided type I error of 0.025 and 90 per cent power to detect an excess death rate in the ancrod group of 29 per cent compared to 18 per cent on placebo. This sequential plan was updated following the recruitment of every 20 patients. 

The sequential planning for the systems C02-Diphenyl and C02-n-Propylbenzene is shown in Tables 2 and 3, respectively. In Figure 1 is depicted the Hunter-Reiner and Ferraris-Forzatti deviations for the C02-n-Propylbenzene system. It can be noted that the selected points for both methodologies are (essentially) the same. This can be explained due to the very small estimated variances of the responses and, hence the Ferraris-Forzatti methodology reduces to the Hunter-Reiner, as can be verified by Equations (5) to (7). This occurred because of, for the systems studied here, the parameters were estimated with small uncertainties. So, the additional effort of the Ferraris-Forzatti methodology is not justified for these systems (the same result was obtained for the C02-Diphenyl), However, the same can not be true when considering multiple responses. 

Eor a process with k factors and one response, relation (5.117) can be used to estimate the number of experiments needed by a sequential plan ... 

The construction of a sequential plan with k = 2 is shown in Fig. 5.10. Points A B C D are the components of the 2 CFE and points A B C D are the components added to the basis plan. The notation no in the centre of the plan shows that we must repeat the experiments. The recommended values of a dimensionless a, corresponds to the situation when the obtained composition plan keeps almost all the properties of the CFE plan. 

When we select the good value of the dimensionless a, then the corresponding sequential plan remains orthogonal like its CFE basic plan. At the same time, if we do not have any special request concerning a sequential plan, the number of experiments to determine fundamental factors can be drastically reduced to... 

Even though the second order orthogonal plan is not a rotatable plan (for instance see Eqs. (5.114) and (5.115)), the errors of the experimental responses (from the response surface) are smaller than those coming from the points computed by regression. It is possible to carry out a second order rotatable plan using the Box and Hunter [5.23, 5.27] observation which stipulates that the conditions to transform a sequential plan into a rotatable plan are concentrated in the dimensionless a value where a = for k<5 and a = for k>5 respectively. Simulta-... 

Sequential planning is particularly helpful in multiresponse experiments to select informative sets of responses for supplemental events. Replicate... 

The package GREGPLUS, included in Athena Visual Studio, tests user-provided models against data on one or more observed response types and assists sequential planning of experiments. Nonlinear and overparameterized models are handled directly. The following types of information can... 

Some critical information about the retrieved implant can only be obtained immediately at the time of harvesting. Some investigational techniques require sample preparation while others require the sample to be first thoroughly cleaned. Due to the destructive nature of some analytical techniques, they have to be performed only after various other tests have been carried out. Given the limited size of samples, sequential planning of sample analysis is very important. Both the ASTM and ISO implant retrieval standards prescribe a three-stage approach to implant analysis ...

The estimates of constants are refined by methods of sequential planning of precise experiments. If necessary, additional chemical investigations are executed in order to come to conclusions about the most probable mechanism. Fishtik and Datta [57,58] have shown that the fundamental equations of thermodynamics have the property of being decomposed into a linear sum of contributions associated with a unique class of reactions referred to as response reactions. This property can also be used for the discrimination among reaction mechanisms. 

The B,P imposes a further restriction that the potency estimate shall be between 90 and 111 per cent of that claimed the values to limit this are also given. Up to the twelfth pair of guinea pigs the sequential plan itself controls the material adequately. Beyond that the acceptability of the material is controlled by the estimated potency alone.

The B,P. test is based on a sequential plan which permits a 10 per cent chance of accepting material which would cause a rise of 0 78°. 

The pyrogen test of the B.P. fits a sequential plan having the characteristics ... 

A sequential plan may be derived in which these weights are considered sequentially when by definition the variance of a single unit of weight is itself unity. 

The objective of a Project Major Emergency Plan (PMEP) is to ensure that all members of the project s management are able to respond to a major emergency quickly and systematically, by following a sequential plan of action. There is no statutory requirement to include a PMEP within the Health and Safety Plan, but their value has been proved beyond doubt. The remainder of this chapter offers suggestions on the format and development of a PMEP.
