Engineering Graphics in Geometric Algebra
, 2010 We illustrate the suitability of geometric algebra for representing structures and developing algorithms in computer graphics, especially for engineering applications. A number of example applications are reviewed.

Convex functions and inequalities in the secondary school
Lietuvos Matematikos Rinkinys, 2008 A function f : Df → R is called convex if for any x, y ∈ Df the inequality f ( x+y/2 ) \leq (f (x)+f (y) )/2 holds. We prove the main property of the convex fonctions (inequality (4)) and also the inequalities which the arithmetic, geometric, harmonic ...

HETEROGENEITY IN THE DEGREE OF QUASI-GEOMETRIC DISCOUNTING: THE DISTRIBUTIONAL IMPLICATIONS [PDF]
This paper modifies the standard one-sector growth model with uninsurable idiosyncratic risk and liquidity constraints to include multiple types of quasi-geometric consumers. For a calibrated version of the model, we show that a modest difference between

A pentagonal surface patch for computer-aided geometric design [PDF]
, 1981 A vector valued interpolation scheme for a pentagon is described which is compatible with surface patches which have a rectangular domain of definition. Such a scheme could be useful in computer- aided geometric design problems, where a pentagonal patch ...

The Effect of Distinct Geometric Semantic Crossover Operators in Regression Problems [PDF]
, 2015 This paper investigates the impact of geometric semantic crossover operators in a wide range of symbolic regression problems. First, it analyses the impact of using Manhattan and Euclidean distance geometric semantic crossovers in the learning process ...

Exploring the relationship between optic nerve geometry, proptosis, and intraocular pressure in optic neuropathy through MRI [PDF]
Romanian Journal of NeurologyBackground and objectives. Intraocular pressure (IOP) fluctuations can cause visual disturbances that impair daily activities. Optic neuropathy can lead to increased IOP. Magnetic resonance imaging (MRI) is considered a potential predictor of IOP because
