In this paper we analyze normal vector representations. We derive the error of the most widely used representation, namely 3D floating-point normal vectors. Based on this analysis, we show that, in theory, the discretization error inherent to single precision floating-point normals can be achieved by 250.2 uniformly distributed normals, addressable by 51 bits. We review common sphere parameteri...

This paper articulates the concept of space and gender using illustrations from the cultural iconography of Hindu Goddesses. The boundary and control of public and private spaces leading to differences in toleration of women within them is discussed. I apply the popular conception of values outlined within Ramayana and Mahabharata texts as they impacted Goddess Sita and Princess Draupadi. I hav...

Original scientific paper The paper deals with the comparison of usage of three basic types of neural units in order to create the most suitable model predicting determining the final thickness of the alumina layer formed at surface with current density of 1 A∙dm. In addition, the reliability of obtained prediction models, depending on the amount of training data, has been monitored. With prope...

We studied ocular surface pH in 161 subjects. The mean pH for 133 normal volunteers was 7 . 11, SD 1 . 5. We found that older women had a more alkaline pH than other subjects, that the pH shifted from acid to alkaline during the day, that one hour of eyelid closure caused an acid shift in pH, and that pH recovered to baseline values within 40 minutes after acid drop instillation. We explored th...

Handwriting recognition has been one of the active and challenging research areas in the field of image processing and pattern recognition. It has numerous applications that includes, reading aid for blind, bank cheques and conversion of any hand written document into structural text form. Neural Network (NN) with its inherent learning ability offers promising solutions for handwritten characte...

Examining the relationship between brain activity and religious fundamentalism, this study explores whether fundamentalist religious beliefs increase responses to errorrelated words among participants intolerant to uncertainty (i.e., high in the need for closure) in comparison to those who have a high degree of toleration for uncertainty (i.e., those who are low in the need for closure). We exa...
