A unified relational semantics for intuitionistic logic, basic propositional logic and orthologic with strict implication
In this paper, by slightly generalizing the notion of 'proposition' in
'Propositional Logic and Modal Logic - A Connection via Relational Semantics'
by Shengyang Zhong, we propose a relational semantics of propositional language
with bottom, conjunction and imlication, which unifies the relational semantics
of intuitionistic logic, Visser's basic propositional logic and orthologic with
strict implication. We study the semantic and syntactic consequence relations
and prove the soundness and completeness theorems for eight propositional
logics
The State of the Art in Creating Visualization Corpora for Automated Chart Analysis
We present a state-of-the-art report on visualization corpora in automated
chart analysis research. We survey 56 papers that created or used a
visualization corpus as the input of their research techniques or systems.
Based on a multi-level task taxonomy that identifies the goal, method, and
outputs of automated chart analysis, we examine the property space of existing
chart corpora along five dimensions: format, scope, collection method,
annotations, and diversity. Through the survey, we summarize common patterns
and practices of creating chart corpora, identify research gaps and
opportunities, and discuss the desired properties of future benchmark corpora
and the required tools to create them.Comment: To appear at EuroVis 202
Thermal analysis of dual-phase-lag model in a two-dimensional plate subjected to a heat source moving along elliptical trajectories
In this paper, we focus on the study of heat transfer behavior for the
dual-phase-lag heat conduction model, which describes the evolution of
temperature in a two-dimensional rectangular plate caused by the activity of a
point heat source moving along elliptical trajectories. At first, Green's
function approach is applied to derive the analytical solution of temperature
for the given model. Based on the series representation of this analytical
solution, the thermal responses for the underlying heat transfer problem,
including the relations between the moving heat source and the concomitant
temperature peak, the influences of the pair of phase lags and the angular
velocity of heat source on temperature, are then investigated, analyzed and
discussed in detail for three different movement trajectories. Compared with
the results revealed for the common situation that the heat source moves in a
straight line with a constant speed, the present results show quite distinctive
thermal behaviors for all cases, which subsequently can help us to better
understand the internal mechanism of the dual-phase-lag heat transfer subjected
to a moving heat source with curved trajectory.Comment: 15 pages, 41 figure
