Internal Parametricity for Cubical Type Theory [PDF]

open access: yesLogical Methods in Computer Science, 2021
We define a computational type theory combining the contentful equality structure of cartesian cubical type theory with internal parametricity primitives.

Centering: A Parametric Theory and Its Instantiations

open access: yesComputational Linguistics, 2021
Centering theory is the best-known framework for theorizing about local coherence and salience; however, its claims are articulated in terms of notions which are only partially specified, such as “utterance,” “realization,” or “ranking.” A great deal of research has attempted to arrive at more detailed specifications of these parameters of the theory;

Representing Parametric Concepts with Situation Theory [PDF]

open access: yesAnnals of computer science and information systems, 2015
We use higher-order, type-theoretic Situation Theory to model semantic concepts as situation-theoretic objects consisting of parametric information. Situation Theory contributes by representing concepts as classes of parametric objects, in a computational way.

Ancient Chinese architecture in the future –An investigation with parametric modeling tools [PDF]

open access: yesE3S Web of Conferences, 2021
With the flexibility and modularity of the construction system, the ancient Chinese architecture was a configurative system until the modern time when it became figurative with nationalistic symbolism, and lost its flexibility to adapt in different ...

A Parametric Functional Equation Originating from Number Theory

open access: yesAnnales Mathematicae Silesianae, 2022
Let S be a semigroup and α, β ∈ ℝ. The purpose of this paper is to determine the general solution f : ℝ2 → S of the following parametric functional equation f(x1+x2+αy1y2,x1y2+x2y1+βy1y2)=f(x1,y1)f(x2,y2),f\left( {{x_1} + {x_2} + \alpha {y_1}{y_2},{x_1 ...

Focused Information Criterion for Restricted Mean Survival Times: Non-Parametric or Parametric Estimators

open access: yesEntropy, 2022
Restricted Mean Survival Time (RMST), the average time without an event of interest until a specific time point, is a model-free, easy to interpret statistic.

Hull-shape parametric for minimising wave energy

open access: yesEnergy Reports, 2023
This study presents a hull-ship parametric in reducing drag for minimising wave energy by comparing various numerical methods. The methods are Thin-ship theory, Rankine method, and Computational Fluid Dynamics (CFD).

Parametric Resonance in Quantum Field Theory [PDF]

open access: yesPhysical Review Letters, 2003
We present the first study of parametric resonance in quantum field theory from a complete next-to-leading order calculation in a 1/N-expansion of the 2PI effective action, which includes scattering and memory effects. We present a complete numerical solution for an O(N)-symmetric scalar theory and provide an approximate analytic description of the ...
