This volume contains the proceedings of the international workshop Variational Problems in Materials Science. Coverage includes the study of BV vector fields, path functionals over Wasserstein spaces, variational approaches to quasi-static evolution, free-discontinuity problems with applications to fracture and plasticity, systems with hysteresis or with interfacial energies, evolution of interfaces, multi-scale analysis in ferromagnetism and ferroelectricity, and much more.

This is a sweet and magical story about a little boy and his pet cloud named Harold. We have all seen shapes in the sky, but this young boy looks up and finds a special cloud that becomes his friend for life. The two play and share adventures, and the cloud is a reassuring presence. The boy learns that he can count on Harold for support, and that even though he may go away for a little while, as people in our lives sometimes do, their connection assures that Harold will always come back to him. This book speaks to a child's sense of wonder, imagination, friendship, and the ability to...

This collection of articles (the Vercelli conference proceedings) places the theme of scepticism within its philosophical tradition. It explores the English philosophical thinkers, the French context, as well as major Italian figures and Spanish culture. It pays special attention to the relationships between history of philosophical ideas and the problems rising from the history of sciences (medicine, physics, linguistics, historical scholarship) in the 17^th and the18^th centuries.

The sense of touch is fundamental during the interaction between humans and their environment; in virtual reality, objects are created by computer simulations and they can be experienced through haptic devices. In this context haptic textures are fundamental for a realistic haptic perception of virtual objects.

This book formalizes the specific artefacts corrupting the rendering of virtual haptic textures and offers a set of simple conditions to guide haptic researchers towards artefact-free textures. The conditions identified are also extremely valuable when designing psychophysical...
