Abstract. This work introduces a system of algorithms to compute period matrices for general surfaces with arbitrary topologies. The algorithms are intrinsic to the geometry, independent of surface representation. The computation is efficient, stable and practical for real applications. The algorithms are experimented to real surfaces including human faces and sculptures, and applied for surfac...

In Julian Voss-Andreae’s recent work “Synergy,” angular strands of stainless steel tubing cluster together, extending into the air like a metallic Lego braid. “Synergy,” which Voss-Andreae says is “techy, but sensual,” is an homage to collagen, our body’s most abundant protein. Collagen is a tough, flexible molecule that supports ligaments, tendons, cartilage, bones, and teeth. The molecule is ...

A-life sculptures are dynamic art works in which human participants function as co-creators. This paper describes a collaborative project to develop an A-life art work that has as its main component a heterogeneous population of agents. The human interactant is represented within the agent population and their role as co-creator of the artwork is mediated by their presence in the population of ...

Visualizing higher dimensional polytopes through computer graphics offers a way to understand and to analyze these interesting objects. Such advantages can be improved by considering polytopes’ three-dimensional projections which are embedded in our space. In this work we will describe basic methodologies for polytopes’ visualization and the way such procedures assist the creation of sculptures...

introduction toxoplasma gondii is one of the most important pathogen that has adverse effect on reproductive function. evidence acquisition recent studies revealed that infection with t. gondii not only affect female reproduction, also cause male reproductive impairment. in clinical studies, high prevalence of toxoplasmosis in sterile men has been reported. in animal models, toxoplasmosis is as...

The paper presents the final part of the research project carried out by authors, concerning use of photogrammetric approaches to support the archaeological hypotheses on the origin of various sculptures. Connection of the separate pieces to the complete sculptures would allow to identify more accurately their origin. The first part of this research, presented already by the authors in 2006 dur...

Mathematics, as a subject dealing with abstract concepts, poses a special challenge for educators. In students' experience, the subject is often associated with (potentially) unflattering adjectives—"austere", "remote", "depersonalized", and so forth. This paper describes a computer program named HyperGami whose purpose is to alleviate this harsh portrait of the mathematical enterprise. HyperGa...
