Evaluation criteria

Experience has shown that abstract testing of labels is for the most part of limited usefulness. Useful results require a fairly precise statement of what the labeler wants the proposed label to achieve, e.g., the goals of the specific labeling project. Once goals have been decided on there are usually three major criteria against which to evaluate results. 

In developing a label it is crucial that the labeler be able to state what the design must communicate in a given period of exposure time. Testing at various exposure periods will therefore yield desired effectiveness data. 

Optical Efficiency As discussed in above sections, the ability to perceive a label design varies with certain optical characteristics. After establishing the exposure time criterion the labeler must also define the distance at which viewing is to be tested and the level of illumination required and then state what elements of the label are to be perceived and remembered. Two criterion variables are then measured for the test label and compared to another version or to a competitive label. 

Legibility—The number and type of label elements perceived and remembered by the viewer at a given distance, exposure duration and illumination level. (Respondent color weakness should be tested at this step). 

Readability—The ease with which written materials are perceived, remembered and comprehended given the distance, duration of exposure and illumination levels set for the label.

Finally, preliminary diagnostic evaluation criteria, based on preventive identification of critical areas of interest on the monitored item, spatial concentration of localized AE events as compared with average AE event density and evolution of local event concentration vs time and/or plant parameters, have been worked out and submitted to extensive testing under real operation conditions. Work on this very critical issue is still to be consohdated. 

Other Fiber Evaluation Methods. The extent of fiber separation (fiber openness) is an important evaluation criteria that is commonly measured by several techniques, namely ak permeabiUty, adsorbed gas volume, bulk density, and residence (compression and recovery). The adsorption and retention of kerosene is also used as a measure of fiber openness and fiber adsorption capacity (34).

After the conceptual designs for each candidate corrective measure alternative have been developed, each can be compared using the following evaluation criteria ... 

After each issue outlined in the evaluation criteria has been developed for each corrective measure, the selection of the most appropriate alternative can be made. Trade-offs among health risks, environmental effects and other pertinent technical, environmental and human health factors enter into this decisionmaking process. In the RCRA context, cost is not a factor in the selection process except when two or more corrective measure alternatives are determined by EPA to provide similarly adequate levels of protection of human health and the environment. 

Clearly defined assessment criteria. Clearly defining the criteria against which existing PSM programs will be evaluated helps to minimize the margin for error and maximize objectivity. Ill-defined evaluation criteria require the person conducting the assessment to rely solely on individual skill and experience, which may or may not yield objective results. 

What does it really mean to do well on such audits i.e. what evaluation criteria are being used ... 

Usually, there will be a department or individual with a central role in the planning process. You should spend time with these staff developing an understanding both of the planning process and the evaluation criteria they use for including expenditures in their budgets. If your project has top level backing, some costs may be absorbed by corporate this is most likely to be the case if costs are incurred well ahead of any benefits. 

An overall economic evaluation must be made to ensure that the contemplated project for petroleum development will recover sufficient capital to pay for the total cost of development, installation and assembly effort of the company. Further, the capital return must yield a financial return consistent with the overall company risk involved. Thus, it is very important that the petroleum engineer designing a recovery system understand the company s evaluation criteria that will be used by management in judging whether a new project is to go forward. Chapter 7 (Petroleum Economics) has detailed discussions of general engineering economics and product (or project) evaluation criteria. 

Finally, the coupling of SLCA, further evaluation criteria and multi-objective optimisation are demonstrated with the help of a second case study dealing with the improvement of synthesis strategies for ionic liquids (see Section 7.5). 

But as will be seen in paragraphi. 3.3 LEL presents an indirect factor of interest in the estimation of flashpoints and in this respect will be considered as an essential parameter in the study of evaluation criteria of fire hazard. This point of view will be reinforced when using LEL as a parameter in the calculation of the 11 code of fire hazard presented in paragraph 1.5.5.

During the detailed analysis, each alternative is assessed against the evaluation criteria. The results provide decision-makers with sufficient information to adequately compare the alternatives, select an appropriate remedy for a site, and demonstrate satisfaction of the CERCLA remedy selection requirements in the record of decision ... 

The alternatives are evaluated in relation to one another for each of seven evaluation criteria. The purpose of this analysis is to identify the relative advantages and disadvantages of each alternative. Table 16.10 shows how these five alternatives comply with the seven major criteria ... 

Those activities are generally conducted during the course of official registration of a plant-protection product. Because, according to Council Directive 91/414/EEC, the registration procedures and evaluation criteria are currently harmonized between the member states of the European Union, the objective of this paper is to contribute to the discussion about a future Union-wide evaluation and assessment scheme for re-entry exposure.

Many different alternative process configurations can be created for a process in the conceptual design phase. In choosing the most feasible alternative safety should be one of the major evaluation criterias. Therefore information on the safety features of alternative process structures are needed on preliminary process design. 

This phase is intended as a final check of the model as a whole. Testing of individual model elements should be conducted during earlier phases. Evaluation of the model is carried out according to the evaluation criteria and test plan established in the problem definition phase. Next, carry out sensitivity testing of the model inputs... 

Beside these selection criteria, the analysis used evaluation criteria to cover quantifiable and non-quantifiable aspects ... 

These selection and evaluation criteria were applied systematically to four technological fields, three of which contribute to new energy-efficient solutions. Passive houses, for example, with their major components of insulation solutions, window systems, ventilation and control techniques are close to market diffusion within the next ten years. Fuel cells for mobile uses in vehicles, however, are still a long way from market introduction, for instance, because of unresolved problems regarding the deactivation of the membrane electrode assembly (MEA) and the need for cost reductions by about one order of magnitude. Other types of fuel cells for stationary uses may be closer to market introduction, owing to less severe technical bottlenecks and better economic competitiveness. 

As analyzed by philosophers, sociologists, and historians, perhaps the most striking characteristic of scientific work is its penchant for turning up new problems and its elaboration of evaluative criteria for choosing one theory over another. Scientific disciplines identify new problems and solve them. This happens within well-established disciplines and within areas of investigation that become new specialties or disciplines. It is the shared problemsolving activity, then, that initially establishes and ultimately prolongs the disciplinary identity. 

Phase II examined the leaching characteristics of C R materials, full development of a predictive model, and the validation of the overall evaluation methodology. Validation of the methodology was achieved by evaluating a number of C R materials and by broadening the evaluation criteria to include leaching kinetics, reference environments, and impact interpretation. 

Accuracy, Precision, and Detection Limits — Analytical cost, accuracy, precision, and detection limits are the four main evaluation criteria for selecting an analytical method. Detection limit information will not be givdn here, as it is easily obtained from the literature or from instrument manufacturers. The analysis of NBS orchard leaves and bovine liver is often used to demonstrate the accuracy and precision of ICP analysis. We feel that the analysis of United States Geological Survey (USGS) and Canadian Centre for Mineral Energy Technology (CANMET) standard rocks, is a more rigorous test of ICP analytical accuracy because of the resistance to sample... 

Common technical specifications (CTS) are to be adopted by the Article 7.2 Committee (a working group of scientific experts appointed by the Member States) which will apply to devices in Annex II List A and, when required, devices in Annex II List B. There is some uncertainty about the circumstances in which the requirement might apply to List B devices. CTS establish appropriate performance evaluation and re-evaluation criteria, batch release criteria, reference methods, and reference materials. If, for duly justified reasons, manufacturers do not comply with the CTS, they must adopt other solutions which are at least equivalent to these specifications. CTS are intended mainly for the evaluation of the safety of the blood supply and organ donations.
