What Is a Polyolefin? A Critical Overview of Ethylene Copolymers Used as Solar Photovoltaic Module Encapsulants

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
Polyolefin encapsulants are gaining dominance in PV modules, yet confusion persists around PO, POE, and TPO definitions. This study clarifies terminology, reviews materials, and properties and proposes a taxonomy to improve understanding, communication, and reliability in solar module manufacturing.

Liberalization of the Postal Service Market in Europe: Entry with Universal Service and Partial Coverage [PDF]

open access: yes
In the advent of postal market liberalization in several European countries we expect that the incumbent operators anticipate entry by competitors who are not required to offer universal service, i.e.

Exploring strongly coupled land/atmosphere data assimilation for numerical weather prediction

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Soil moisture and soil temperature can be analyzed effectively in a numerical weather prediction system by expanding the atmospheric ensemble‐based data assimilation to update the soil states also. The best results were obtained here using a strongly coupled land/atmosphere data assimilation to assimilate the standard atmospheric observations plus ...

Risk Times in Mission‐Oriented Systems

open access: yesQuality and Reliability Engineering International, EarlyView.
ABSTRACT This article assesses risk times in mission‐oriented systems with high safety standards. We examine critical times under two safety policies. The first requires that the system's reliability function, known the first failure of the components, must exceed a reliability level throughout the mission.
