A Theorem on Preference Aggregation [PDF]
I present a general theorem on preference aggregation. This theorem implies, as corollaries, Arrow's Impossibility Theorem, Wilson's extension of Arrow's to non-Paretian aggregation rules, the Gibbard-Satterthwaite Theorem and Sen's result on the ...

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.This paper proposes an online method for calculating loop closing current that addresses the uncertainties in source and load fluctuations. By using a dual‐stack dynamic monitoring system and Thevenin's theorem for network modelling, the method accurately calculates both steady‐state and transient loop closing currents.

A Unifying Impossibility Theorem [PDF]
This paper considers social choice correspondences assigning a choice set to each non-empty subset of social alternatives. We impose three requirements on these correspondences: unanimity, independence of preferences over infeasible alternatives and ...

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.This paper first derives an analytical expression for the transient overvoltage (TOV) magnitude at critical nodes in the system caused by DC blocking (DCB) faults. Subsequently, an analytical formula is developed to characterize the relationship between the multiple renewable energy stations short circuit ratio (MRSCR) and the transient voltage rise ...

Dilworth's Theorem Revisited, an Algorithmic Proof [PDF]
Dilworth's theorem establishes a link between a minimal path cover and a maximal antichain in a digraph.A new proof for Dilworth's theorem is given. Moreover an algorithm to find both the path cover and the antichain, as considered in the theorem, is ...

Modal Analysis of Power System With High IBR Penetration Based on Impedance Models
IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.A unified physical interpretation of modal analysis based on the impedance model (MAI), based on the electrical distance perspective is further presented.To make MAI more applicable and accurate, a new total evaluation index is proposed to fix the potential misjudgment when computing the admittance sensitivity factor.

A proof of the four-colour theorem
, 2013 The four-colour problem remained unsolved for more than a hundred years has played a role of the utmost importance in the development of graph theory. The four-colour theorem was confirmed in 1976, which is not completely satisfied due to: i) part of the

A generalisation of the nonlinear small-gain theorem for systems with abstract initial conditions
, 2013 We consider the development of a general nonlinear small-gain theorem for systems with abstract initial conditions. Systems are defined in a set theoretic manner from input-output pairs on a doubly infinite time axis, and a general construction of the ...

Disproof of Bell's Theorem: Further Consolidations [PDF]
, 2007 The failure of Bell's theorem for Clifford algebra valued local variables is further consolidated by proving that the conditions of remote parameter independence and remote outcome independence are duly respected within the recently constructed exact ...

Kochen-Specker theorem for von Neumann algebras [PDF]
, 2005 The Kochen-Specker theorem has been discussed intensely ever since its original proof in 1967. It is one of the central no-go theorems of quantum theory, showing the non-existence of a certain kind of hidden states models. In this paper, we first offer a
