The validation of satellite ocean color data products is a critical component in establishing their measurement uncertainties, assessing their scientific utility, and identifying conditions for which their reliability is suspect. Such efforts require a considerable amount of high quality in situ data, preferably consistently processed and spanning the satellite mission lifetime. This paper outl...

The high energy consumption of GPS modules has kept long-term outdoor localisation with battery-powered devices an unsolved challenge. While lowpower sensors can trigger GPS sampling to reduce energy consumption, validating the long-term reliability of these sensors in unconstrained environments is challenging due to sensor drifts and the lack of ground truth data in the field. We describe the ...

Why Read This Chapter? To help you decide how to check your simulation – both against its antecedent conceptual models (verification) and external standards such as data (validation) – and in this way help you to establish the credibility of your simulation. In order to do this the chapter will point out the nature of these processes, including the variety of ways in which people seek to achiev...

BACKGROUND The DOGRISK questionnaire is an internet-based ongoing study of canine nutrition, living environment, and disease. Here we aim to assess the performance of the questionnaire using data from the first three years in relation to some descriptive and disease variables. We used associated questions, official register records, test-retest repeatability, and email/mail contact with questio...

This paper intended to record the process of developing and validating a Semantic Differential Scale assess teacher’s belief on socially disadvantaged students in Indian context. Social Identity Theory (SIT) Stereotype Content Model (SCM) has been adopted. Following new method SDS proposed by Ding et al. (2008), resulted 15-item scale with three-factorial structure. The reliability validity acc...
