DC Side Impedance Modelling of an Actual Line Commutated Converter High Voltage Direct Current System and DC Resonance Characteristics

High Voltage, EarlyView.
ABSTRACT The stability analysis of Line Commutated Converter High Voltage Direct Current (LCC‐HVDC) is of considerable engineering importance. Establishing its analytical mathematical model helps to analyse stability and the factors that affect stability of the system.

Ideals and congruences in $L$-algebras and pre-$L$-algebras [PDF]

Categories and General Algebraic Structures with Applications
We link the recent theory of $L$-algebras to previous notions of Universal Algebra and Categorical Algebra concerning subtractive varieties,  commutators, multiplicative lattices, and their spectra.

Revisiting Ontology to Reshape Transgenerational Justice

Global Policy, EarlyView.
ABSTRACT This article develops a philosophical framework for understanding transgenerationality as a foundational concept for intergenerational justice. Drawing on social ontology and the philosophy of action, it introduces the notion of transgenerational civitas—a temporally extended community composed of past, present and future generations.

q-Uncertainty Relations

, 1997
As one would anticipate from the realization of the q-commutators by difference operators, the states of maximum localization are smeared delta functions depending on q.Comment: 10 pages, tex ...

Computerized dynamic assessment of seriational thinking modifiability: Effects of mediation on seriation and readiness for math among kindergarten and grade 1 children

British Journal of Educational Psychology, EarlyView.
Abstract Background and Aims A vast body of theory and research highlights the operation of seriation as a prerequisite to mathematical thinking in young children. However, there is limited evidence that seriation interventions improve early years mathematics.

Lieb-Robinson bounds for commutator-bounded operators

, 2010
We generalize the Lieb-Robinson theorem to systems whose Hamiltonian is the sum of local operators whose commutators are bounded.Comment: 5 pages, minor editorial ...

Fused Collapsing for Wide BVH Construction

Computer Graphics Forum, EarlyView.
Abstract We propose a novel approach for constructing wide bounding volume hierarchies on the GPU by integrating a simple bottom‐up collapsing procedure within an existing binary bottom‐up BVH builder. Our approach directly constructs a wide BVH without traversing a temporary binary BVH as done by previous approaches and achieves 1.4 – 1.6 × lower ...

Pseudodifferential operators and their commutators on Morrey type spaces

Demonstratio Mathematica
This paper discusses the boundedness of the commutators generated by pseudodifferential operators with Lipschitz functions, and sets up the sufficient condition such that these operators are bounded on classical Morrey spaces and generalized Morrey ...

Canonical Commutation Relation Derived from Witt Algebra

Mathematics
From an arbitrary definition of operators inspired by oscillators of Virasoro, an algebra is derived. It fits the structure of Virasoro algebra with null central charge or Witt algebra. The resulting formalism has yielded commutators with a dependence on
