Changing Euler Diagram Properties by Edge Transformation of Euler Dual Graphs [PDF]
, 2009 Euler diagrams form the basis of several visual modelling notations, including statecharts and constraint diagrams. Recently, various techniques for automated Euler diagram drawing have been proposed, contributing to the Euler diagram generation problem:

Drawing Graphs in Euler Diagrams [PDF]
, 2004 We describe a method for drawing graph-enhanced Euler diagrams using a three stage method. The first stage is to lay out the underlying Euler diagram using a multicriteria optimizing system. The second stage is to find suitable locations for nodes in the

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.
