Summary: This study proposes an extended theoretical formula to characterize the relationship between geometric concentration ratio and arbitrary incidence-angle range in vehicle-integrated concentrator photovoltaics (VICPVs). The maximum annual optical efficiency can be achieved by selectively collecting sunlight within a specific incidence-angle range, regardless of geographic location. The design of solar concentrators based on the formula shows that the optical efficiencies of systems with different lens types are 64-89% of the theoretical limit, depending on the location for C-g = 3.5x. However, there is further room for improvement in concentrator design for practical applications.

Summary: This paper presents a general theoretical framework for ordinal classification methods, which use pairwise comparisons to assign actions to classes. The new assignment rules use a reflexive binary relation, S, and its asymmetric part, P. These rules fulfill fundamental properties and relax the requirements for limiting and representative profiles compared to other pairwise classification methods. Many ordinal classification methods can be derived from this proposal, each consisting of two correlative assignment rules. Various existing methods, such as ELECTRE TRI-nB and ELECTRE TRI-nC, can be seen as particular cases of this generalized framework.
