A Graph Theoretic Approach to General Euler Diagram Drawing [PDF]
, 2010 Euler diagrams are used in a wide variety of areas for representing information about relationships between collections of objects. Recently, several techniques for automated Euler diagram drawing have been proposed, contributing to the Euler diagram ...

Euler–Lagrange equations for the spectral element shallow water system [PDF]
, 2006 We present the derivation of the discrete Euler–Lagrange equations for an inverse spectral element ocean model based on the shallow water equations. We show that the discrete Euler–Lagrange equations can be obtained from the continuous Euler–Lagrange ...

Numerical aspects of two coupled harmonic oscillators
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2020 In this study an interesting symmetric linear system is considered. As a first step we obtain the Lagrangian of the system. Secondly, we derive the classical Euler- Lagrange equations of the system.

The Impact of Shape on the Perception of Euler Diagrams [PDF]
, 2014 Euler diagrams are often used for visualizing data collected into sets. However, there is a significant lack of guidance regarding graphical choices for Euler diagram layout.

How Should We Use Colour in Euler Diagrams? [PDF]
, 2014 This paper addresses the problem of how best to use colour in Euler diagrams. The choice of using coloured curves, rather than black curves, possibly with coloured fill is often made in tools that automatically draw Euler diagrams for information ...

Artificial-Delay Adaptive Control for Under-actuated Euler-Lagrange Robotics [PDF]
, 2021 Artificial-delay control is a method in which state and input measurements collected at an immediate past time instant (i.e. artificially delayed) are used to compensate the uncertain dynamics affecting the system at the current time.

On networked Euler–Lagrangian systems consensus under switching topologies
The Journal of Engineering, 2021 This paper studies the consensus of multiple Euler–Lagrangian systems with dynamic uncertainties and the challenges to be solved lie on weak interaction, time‐varying interaction and parametric uncertainties.

Evaluating the Comprehension of Euler Diagrams [PDF]
, 2007 We describe an empirical investigation into layout criteria that can help with the comprehension of Euler diagrams. Euler diagrams are used to represent set inclusion in applications such as teaching set theory, database querying, software engineering ...
