This paper reviews ways in which many artists have constructed large sculptures from tubular elements, ranging from single cylinders to toroidal or knotted structures, to assemblies of a large number of bent tubes. A few parameterized generators are introduced that facilitate design and evaluation of a variety of such sculptural forms.

research on ancient dna (adna) has the potential to enable molecular biologists and archeologists to decipher certain aspects of history by direct looking into the past. however, several major problems in this field limit the applicability of adna studies, most importantly contamination with modern dna and postmortem dna degradation. in this study we extracted and analyzed adna obtained from ~3...

We present a graphical user interface that allows an artist to virtually design and visualize net sculptures. Net sculptures consist of net pieces that are seamlessly connected to each other and to fixed rails. They are flexible and hence dynamic under external forces such as gravity and wind. The interface that we describe allows an artist to create net sculptures made up of multiple net piece...

This paper introduces a design guideline to construct a family of symmetric, connected sculptures with high number of holes and handles. Our guideline provides users a creative flexibility. Using this design guideline, sculptors can easily create a wide variety of sculptures with a similar conceptual form.

cystic echinococcosis caused by echinococcus spp. is considered endemic in iran. to clarify the pre­sent status of hydatidosis in iran the present review article is presented. authentic databases and search engines from 1996 onwards were utilized to enquire the situation of the disease in iran. human hydati­dosis is responsible for approximately 1% of admission to surgical wards and the rate of...

animal welfare considerations are becoming increasingly important for farming of animals, both in tunisia and internationally. practices which may have once been deemed acceptable are now being reassessed in the light of new knowledge and changing attitudes. and a clearly defined concept of welfare is needed for use in precise scientific measurements. if animal welfare is to be compared in diff...

Charles Perry’s monumental sculpture Solstice is analyzed and its generative geometrical logic based on a twisted toroidal sweep is captured in a computer program with interactively adjustable control parameters. This program is then used to generate other models of ribbed sculptures based on one or more interlinked torus knots. From this family of sculptures related to Perry’s Solstice we deri...
