KPV: A clear-sky index for photovoltaics
Solar Energy, 2014 Abstract The rapidly growing installed base of distributed solar photovoltaic (PV) systems is causing increased interest in forecasting their power output. A key step towards this is accurately estimating the output from a PV system based on the known output from a nearby PV system.

Some Psychometric Properties of the Brazilian CDC Clear Communication Index
HLRP: Health Literacy Research and Practice, 2022 The Centers for Disease Control and Prevention (CDC) Clear Communication Index (CCI) was cross-culturally adapted to Brazilian Portuguese (BR). It was necessary to analyze the reliability and validity of the BR-CDC-CCI for its use in Brazil. This study aimed to evaluate the psychometric properties of the instrument in its Brazilian version.

A Semi-Analytical Model for Separating Diffuse and Direct Solar Radiation Components
Applied Sciences, 2022 The knowledge of the solar irradiation components is required by most solar applications. When only the global horizontal irradiance is measured, this one is typically broken down into its fundamental components, beam and diffuse, by applying an ...

Using the Clear Communication Index to Improve Materials for a Behavioral Intervention [PDF]
Health Communication, 2018 Ensuring that written materials used in behavioral interventions are clear is important to support behavior change. This study used the Clear Communication Index (CCI) to assess the original and revised versions of three types of written participant materials from the SIPsmartER intervention. Materials were revised based on original scoring. Scores for
