We show that the geometric Hermite interpolant can be easily calculated without solving a system of nonlinear equations. In addition we give geometric conditions for the existence and uniqueness of a solution to the interpolation problem. Finally we compare geometric Hermite interpolation with standard cubic Hermite interpolation. x1 Introduction Since parametric representations of curves are n...

the effect of drought on the seed yield and some associated characteristics of common been under normal and drought stress conditions and determination of durable genotypes to drought were studied by planting 32 genotypes in two separate augmented designs in normal and stress conditions. these genotypes were evaluated in randomized complete block design with 3 replications in the field of facul...

in order to evaluate drought tolerance of cultivars and advanced grain sorghum lines, an experiment was conducted as split-plot on randomized complete blocks design with three replications at experimental field of seed and plant improvement institute, karaj in 2009. three levels of irrigation regimes including normal irrigation (ir0=60 mm), moderate stress (ir2=120 mm) and sever stress (ir3=180...

in order to study and determine the most effective traits, drought tolerance indices and identify tolerant genotypes in terminal drought stress on the cowpea, an experiment was carried out based on an augment design in two separate conditions in the karaj farm, faculty of agriculture, tehran university in 2009. drought stress was imposed by cutting irrigation after flowering against normal irri...

The context of this paper is the use of formal methods for topology-based geometric modelling. Topology-based geometric modelling deals with objects of various dimensions and shapes. Usually, objects are defined by a graph-based topological data structure and by an embedding that associates each topological element (vertex, edge, face, etc.) with relevant data as their geometric shape (position...

The reflectance factors of transparent fibers, free delustering agent, are predicted by geometric as well as Kubelka-Munk models. Transparent fibers are simulated by a net of glass capillary tubes containing different solutions of dyestuffs. Based on the results, prediction of the reflectance factor of capillary net by geometric model is relatively better than those obtained from Kubelka-Munk...

Motivation Recently, many researchers have begun to attempt to solve dense correspondence problem for more challenging images which have high variability in terms of photometric and/or geometric conditions [4]. For these challenging scenarios, there exist two principal bottlenecks which make conventional methods provide limited performances; (1) photometric variations derived from different cam...
