Heat kernel asymptotics for scaling limits of isoradial graphs
We consider the asymptotics of the discrete heat kernel on isoradial graphs for the case where the time and the edge lengths tend to zero simultaneously. Depending on the asymptotic ratio between time and edge lengths, we show that two different regimes arise, corresponding to the short-time asymptotics of the heat kernel on (i) Euclidean spaces and (ii) on graphs
Enseñanza de la escritura de Max Aub: comprensión y memoria
Este texto analiza a obra testimonial de Max Aub sobre su experiencia en los campos de concentración en Francia desde una perspectiva de discursos comparados. Para destacar las estrategias de la escritura del autor recuperables por otros proyectos discursivos que persigan la sensibilización y la denuncia a través del cruce entre la comunicación y la éticaThis text analyses the testimonial work of Max Aub about his experience in the French concentration camps in France from comparative discourses approach. It emphasizes the writing strategies used by the author useful for other awareness and denounce discourses through the dialogue among communication and ethic

Max Frisch's novel: Stiller. A study
The attempt is made in the following study to present an interpretation of the novel "Stiller" by the Swiss author, Max Frisch, by tracing through the novel the dominant themes of the graven-image or 'Bildnis' and that of the problem of freedom with reference to the novel's main character.

A Transfer Report on the Development of a Framework to Evaluate Search Interfaces for their Support of Different User Types and Search Tactics
As the understanding of search systems, user needs and seeking strategies is developing, the design of search user interfaces is evolving to support more complicated and exploratory forms of search. With the design of new search features that enable these richer modes of exploration, comes the need to better understand the support they provide. In this report a new evaluation framework is presented that analyses search features for how they a) contribute to an overall interface, b) allow users to carry out different search tactics, and c) support different types of users and their needs. The novel contributions of the framework improve on some of the limitations of typical user studies, and allow search systems to be systematically analysed in much more detail and in much less time. The presented evaluation framework is then validated in three ways. First the validity of the models used as the building blocks of the framework are investigated through related work. Second the method of integrating these building-block models is validated and strengthened by consensus of expert opinion. Third, the overall approach is validated by comparing its analyses to the results of previously carried out user studies. The validation process has shown both the value of the framework and identified areas of future work that should be addressed for the framework to be completed. This report concludes with the set of contributions that the framework makes, and why the remaining work will be challenging, but critical to the final design
Sub-Riemannian Random Walks: From Connections to Retractions
We study random walks on sub-Riemannian manifolds using the framework of retractions, i.e., approximations of normal geodesics. We show that such walks converge to the correct horizontal Brownian motion if normal geodesics are approximated to at least second order. In particular, we (i) provide conditions for convergence of geodesic random walks defined with respect to normal, compatible, and partial connections and (ii) provide examples of computationally efficient retractions, e.g., for simulating anisotropic Brownian motion on Riemannian manifolds
Efficient Itô diffusions on Riemannian manifolds
A generalization of Donsker’s theorem states that, under mild conditions, Itô diffusions
on complete Riemannian manifolds can be approximated by geodesic random walks. Generally,
this does not provide an efficient way of simulating Itô diffusions on Riemannian
manifolds, since a non-linear differential equation must be solved at every step. In the
special case of Brownian motion on a compact manifold, approximate geodesic random
walks based on approximations of the exponential map called retractions have been proposed
and shown to be efficiently computable and convergent to Brownian motion. Using
the theory of Feller processes, we generalize the method of retraction-based random walks
and its convergence results to Itô diffusions on compact Riemannian manifolds under mild
assumptions on the drift and diffusion terms
