An oriented-design simplified model for the efficiency of a flat plate solar air collector [PDF]
, 2010 In systems design, suitably adapted physical models are required. Different modelling approaches for a solar air collector were studied in this paper. First, a classical model was produced, based on a linearization of the conservation of energy equations.

OF RENT COLLECTORS AND DEBT COLLECTORS
Obiter, 2023 This note examines the question whether an estate agent collecting or receiving monies in the course of his or her business as an estate agent is also a “debt collector” as defined in the Debt Collectors Act 114 of 1998. The matter is of some importance: if the answer is in the affirmative it would mean that estate agents mandated to collect rentals ...

Energetic Comparison of Linear Fresnel and Parabolic Trough Collector Systems [PDF]
, 2012 Within the last years, Linear Fresnel (LF) collector systems have been developed as a technical alternative to parabolic trough collector (PT) systems. In the past, LF systems focused on low- and medium temperature applications.
