A general overview of the problem of automatically generating aesthetically pleasing drawings of graphs is presented. Requirements particular to diagrams in Rational Rose is discussed. The Sugiyama layout algorithm and the Spring Embedder algorithm together with a number of proposed modifications and improvements to these algorithms are discussed. Examples of drawings generated by these algorit...

This paper presents the results of an evaluation of the effects of a local water harvesting project in Kenya concerning the construction of small scale sand dams by communities. Sand dams are small structures built in ephemeral rivers to store excess water to overcome periods of drought. For this evaluation we developed a method using socio-economic vulnerability indicators, which are linked to...

1. The rate of urine production in the terrestrial crabs Gecarcinus lateralis (Freminville) and Cardisoma guanhumi Latreille maintained on s.w.-moist sand was measured by inulin clearance. 2. The inulin U/B ratios in both species rose to about unity after 48 h, and remained at this level. It was concluded that neither species withdrew water from the primary urine. 3. The relatively high rate of...

Abstract Human communication is by default polysemiotic : it involves the spontaneous combination of two or more semiotic systems , most important ones being language gesture and depiction . We formulate an original cognitive-semiotic framework for analysis polysemiosis, contrasting this with familiar based on ambiguous term “multimodality.” To be fully explicit, we developed a coding system ut...

Vanuatu sand drawing has been listed by UNESCO since 2006 and both fascinated puzzled researchers from various disciplines for over a century. The inherent multi-dimensionality of the practice makes analysis complex, until very recently developing systematic methodology to study this intangible art form was difficult. This paper aims contribute filling gap with corpus drawings documented on isl...

Parametric and feature-based design is a modern approach for product modeling to save time and money during the product development and manufacturing process, especially in the preliminary stages of design. Parametric modeling can be used to improve customer satisfaction by facilitating rapid product customization to achieve specific customer requirements. In this paper, we discuss a parametric...

in desert areas high temperature and low precipitation limit growth and development of plants. under this circumstances wind becomes the most important erosion and transportation factor in these areas. there are four great sand masses in the central part of dasht-e-kavir namely rig-e-jen, rig-e-sargardan (shotori or halvan), rig-e-kharturan, and rig-e- chah-e-jam. these great sandy masses show ...

An increase in intracellular Ca2+ concentration ([Ca2+]) and morphological were simultaneously observed by epifluorescence and differential interference contrast (DIC) microscopy during fertilization of the sand dollar, Clypeaster japonicus. [Ca2+], which was detected by a Ca2+ indicator, Fluo-3, initially increased just beneath the sperm-attached site on the egg surface 8.6 sec after attachmen...
