  A Priori and A Posteriori [Internet Encyclopedia of Philosophy]
We can thus refine the characterization of a priori justification as follows: one is a priori justified in believing a given proposition if, on the basis of pure thought or reason, one has a reason to think that the proposition is true.
While these differences may seem to point to an adequate basis for characterizing the relevant conception of experience, such a characterization would, as a matter of principle, rule out the possibility of contingent a priori and necessary a posteriori propositions.
More needs to be said, however, about the positive characterization, both because as it stands it remains less epistemically illuminating than it might and because it is not the only positive characterization available.

  Parts characterization - OpenWetWare
Characterization of standard biological parts is an essential step in enabling construction of more complicated devices and systems based on these parts.
A standard method of characterization (or several standards) will better enable sharing of parts between different laboratories, as well as improve our ability to design devices.
This is an attempt to organize some of the available characterization methodologies as well as the type of information that they generate.

  Characterization Accuracy Requirements
The characterization requirements used for an MFL inspection depend on the pipeline operator's goals in performing the inspection.
Characterization accuracy is important in differentiating between defects, imperfections, pipeline components, and non-relevant indications.
Characterization accuracy is also a function of the number of inspection indications found on a line.

Descriptive hazard characterization serves to structure and present the available information on the spectrum of human illness associated with a particular pathogen, and how this is influenced by the characteristics of the host, the pathogen and the matrix, as indicated in Figure 3.
When a hazard characterization is being undertaken, one of the initial activities will be to evaluate the weight of evidence for adverse health effects in humans in order to determine, or confirm, the ability of the pathogen to cause disease.
When not already included in the characterization of the pathogen, specific consideration should be given to the intrinsic properties of the pathogen that influence infectivity, virulence and pathogenicity; their variability; and the factors that may alter the infectivity, virulence or pathogenicity of the microorganism under consideration.

 Research: Characterization
Characterization processes span the range from molecular to landscape scales, and significant knowledge gaps exist that impair accurate risk assessment, limit remediation and restoration activities, and often make cost-effective management decisions difficult or impossible.
Characterization also includes elucidation of the environmental and ecological patterns and processes that influence organismal distributions, (micro) biological diversity and function, health, reproduction, mortality, and other factors.
Characterization is necessary to construct models of the way natural and engineered systems function both in the presence and absence of environmental perturbations such as anthropogenic contamination.

Such characterization can help utilities assess the potential impact of the deposits on steam generator integrity and performance and plan for deposit removal by mechanical or chemical means.
Characterization of deposits is necessary to determine the potential for deleterious effects to occur.

 An Introduction to Workload Characterization
Therefore, workload characterization is the science that observes, identifies and explains the phenomena of work in a manner that simplifies your understanding of how the network is being used.
Workload characterization provides the equivalent view of a network - scale drawings detailing the total bandwidth of the network, the significance of users, and the bandwidth requests of a particular workload.
Not only does the characterization allow you to easily compare the workload of one server to another and observe general trends, the graph allows you to communicate accurate information about the server's workload characteristics to others.

 Bench Characterization of ADCs Using a Low-Cost PC-Based Data-Acquisition Board - Maxim/Dallas
In cases where design errors need to be identified and corrected, this rapid bench characterization allows for a controlled, iterative evaluation loop (that is, hypothesis, experimental design, measurement and evaluation of results, leading to further hypothesis, experimental design, etc.) and consequently faster identification of the design error.
This approach works well for signals traveling from the characterization board to the PC interface card, because terminating resistors can be placed at the source end of the characterization board.
A number of advantages of this approach to bench characterization have been pointed out and include ease of interfacing to complex devices, more complete and faster characterization of both static and dynamic parameters, the ability to improve design-error identification, and faster resolution of correlation issues.

The conclusions of the risk characterization are only valid if the extent of the release has been properly defined and all possible affected media and migration pathways have been considered.

When the risk characterization does not demonstrate that a condition of "No Significant Risk of harm" exists, the conclusion of the risk characterization should clearly state that fact, and should acknowledge that remediation would be necessary to achieve a permanent solution.
