Pars plana vitrectomy for acute infectious endophthalmitis can be challenging due to severe inflammation in the anterior chamber creating significant media opacity. We describe a surgical technique combining limbal based vitrectomy and pars plana vitrectomy to manage acute infectious endophthalmitis. Limbal based vitrectomy facilitates removal of anterior chamber fibrin and inflammatory membran...

The Geometry modeller is a key component of the Geant4 toolkit [1,2]. It has been designed to exploit at the best the features provided by the Geant4 simulation toolkit, allowing the description of the geometrical structure of complex detectors in a natural way, ranging from a few up to hundreds of thousands volumes of the LHC experiments, as well as human phantoms for medical applications or d...

This paper describes RolEnact: a process-modelling notation used to provide enactable models of process instances. The paper shows how RolEnact models may be produced which are equivalent to role activity diagrams (RADs). This allows the modeller to describe processes in a notation (RADs); which can be understood both by process consultants and process users, whilst retaining the ability to gen...

Granularmaterials—conglomerates ofmacroscopic particles —are challenging systems to model. It is simply too costly to simulate the huge amount of particles in most systems in full detail. Even most intricate simulation methods, such as discrete particle simulations for modelling the full particle dynamics and direct numerical simulations to model a fluid flowing through the granular material, n...

In software engineering, regression testing allows to validate expected properties of a software after each change of the code. In this paper, we present a tool that transfers this idea to the area of visual modelling, in particular to ı̇∗ modelling. The modeller can select typical properties (expressed in natural language) from a menu. Then these properties will be stored together with the ı̇∗ m...

Given any observed demand behavior by means of a demand function, we quantify by how much it departs from rationality. The measure of the gap is the smallest Frobenius norm of the correcting matrix function that would yield a Slutsky matrix with its standard rationality properties (symmetry, singularity, and negative semidefiniteness). A useful classification of departures from rationality is s...
