A Linear Category of Polynomial Diagrams [PDF]

open access: yes, 2012
We present a categorical model for intuitionistic linear logic where objects are polynomial diagrams and morphisms are simulation diagrams. The multiplicative structure (tensor product and its adjoint) can be defined in any locally cartesian closed ...

One-Class Drift Compensation for an Electronic Nose

open access: yesChemosensors, 2021
Drift compensation is an important issue in an electronic nose (E-nose) that hinders the development of E-nose’s model robustness and recognition stability.

Study of Natural Ventilation Strategies in the São Cristóvão Church in Lisbon Using a Multizone Airflow Model

open access: yesApplied Sciences, 2023
Visitors have a significant impact on the indoor climate of buildings housing works of art, and the relationship between the number of visitors, the indoor air quality and the protection of exposed works of art is an important factor in the overall study

⊗-Pure model structure on the category of N -complexes

open access: yesExtracta Mathematicae
Let G be a closed symmetric monoidal concrete Grothendieck category. In this paper, we introduce a model structure on (CN (G), P⊗dw ) the exact category of N -complexes with the degree-wise ⊗-pure exact structure.

A Graph Theoretic Perspective on CPM(Rel) [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2015
Mixed states are of interest in quantum mechanics for modelling partial information. More recently categorical approaches to linguistics have also exploited the idea of mixed states to describe ambiguity and hyponym / hypernym relationships.

Development and Implementation of a Four-Tier Close-Ended Test to Analyze Students' Misconceptions of Optical Instruments

open access: yesTadris: Jurnal Keguruan dan Ilmu Tarbiyah, 2023
The research aims to develop a four-tier test for optical instrument materials. The method used in this study is a 4D design that includes defining, designing, developing, and disseminating. The instrument used consisted of fifteen items in the form of a

Semantics of higher inductive types

open access: yes, 2019
Higher inductive types are a class of type-forming rules, introduced to provide basic (and not-so-basic) homotopy-theoretic constructions in a type-theoretic style.

The social dynamics of basins of attraction

open access: yesEcology and Society, 2021
In this paper we conceptualize transformations as societal shifts from one basin of attraction to another. Such shifts occur when a society's information processing system is no longer fit to deal with the dynamics with which the society is involved.

Closed model categories for uniquely S-divisible spaces

open access: yesJournal of Pure and Applied Algebra, 2003
For each integer n > 1 and a multiplicative system S of non-zero integers, we give a distinct closed model category structure to the category of pointed spaces Top and we prove that the corresponding localized category Ho(Top(S,n)), obtained by inverting the weak equivalences, is equivalent to the standard homotopy category of uniquely (S,n)-divisible,
