We consider the problem of generating art with a computer system, as it relates to the understanding of a drawing style. Our system in its present development is able to sketch faces automatically, starting from a picture, typically a photographic snapshot of a scene with humans. Once a digital image is considered, the system automatically finds where some of the faces (or face-like patterns) a...

I come from a family of lawyers. When I was growing up, the only scientist in the family was my uncle, who was a physicist. But I was interested in science, and as a boy collected rocks and kept my “chemistry cabinet” in a spare room at my father’s law firm in Rome where I smelled up the place from time to time with failed experiments. When I finished high school at the Liceo Classico Torquato ...

verbal broadsides. Two chapters are devoted to differential diagnosis. rhe wvork is based on the author's experience of 1,000 operations for lumbar disc lesions, but he omits to state how nany cases this represents altogether. However, he mentions that operation is carried out in somewhere between 10 and 20 per cent of cases, so that he must have seen a veiy large rnulmber o,f patients with low...

Retrieving photography ideas corresponding to a given location facilitates the usage of smart cameras, where there is a high interest among amateurs and enthusiasts to take astonishing photos at anytime and in any location. Existing research captures some aesthetic techniques and retrieves useful feedbacks based on one technique. However, they are restricted to a particular technique and the re...

We compute (algebraically) the Euler characteristic of a complex of sheaves with constructible cohomology. A stratified Poincaré-Hopf formula is then a consequence of the smooth Poincaré-Hopf theorem and of additivity of the Euler-Poincaré characteristic with compact supports, once we have a suitable definition of index. AMS classification: 55N33 57R25

As to the relationship between extraverted disposition and preference for social communication on Internet community, there have been two hypotheses: “Social Enhancement” (“Rich Get Richer”) and “Social Compensation” (“Poor Get Richer”). In this paper, we examined the role of using real-life portrait as facial picture in determining whether an extraverted user would be sociable on Internet comm...
