Revisit and optimisation of spectral data collection techniques from vegetation using handheld non-imaging spectroscopic sensor for minimising errors Spectral data are now-a-days widely used for assessment of biochemical, biophysical and structural traits of vegetation by analysing their spectral signatu......
Is interrater reliability described? Are the techniques for recording observations described? How is self-reported data collected? With this type of strategy, the subjects or participants provide data Can be done using the following strategies: Interviews Questionnaires or surveys Scales What do unstruct...
Outlining your business’s goal for collecting data will help you determine which data collection methods to use, how much to collect, and what to do with the information once you have it.2. The type of data you need to collectBefore you can start collecting data, you need to know what...
These data access techniques allow you to interact with the conceptual entities defined within the entity model rather than the objects of a physical store such as a relational database. The data model and associated mappings are created by using either the visual designer tool or by manually edi...
where refactoring tools and unit testing techniques are generally more effective, then create the database model later when the object model is stable. The Data Mapper pattern is also more applicable to the Domain Driven Design architectural approach that is gaining in popularity in the .NET ...
Use of questionnaires (1) Definition of Questionnaires Techniques of data collection in which each person is asked to respond to the same set of questions in a predetermined order Adapted from deVaus (2002) Use of questionnaires (2) When to use questionnaires For explanatory or descriptive researc...
This article compared the performance of several alternative techniques to solve the same problem. The approach has been to use standard interfaces as they’re described and to assume a simple shared-memory model for the processors and threads. There was, however, no significant effort to probe ...
Big data collection entails structured, semi-structured and unstructured data generated by people and computers. Big data's value doesn't lie in its quantity, but rather in its role inmaking decisions, generating insights and supporting automation-- all critical to business success in the...
