Rounding, stipulation and notation issues in measurement

Some issues related to double rounding

Double rounding is a phenomenon that may occur when different floatingpoint precisions are available on the same system. Although double rounding is, in general, innocuous, it may change the behavior of some useful small floating-point algorithms. We analyze the potential influence of double rounding on the Fast2Sum and 2Sum algorithms, on some summation algorithms, and Veltkamp’s splitting.

Issues of Rendering Arabic Mathematical Notation in Computer Software

Typeface technology has become quite complex over the years. There have been several attempts to use Arabic calligraphic styles in computer typography. These proved to be useful, but they had their shortcomings and drawbacks. Computational time cost and lack of Arabic script documentation were the most crucial issues with that work. In a few studies, the accuracy of results obtained also was an...

Descriptive theories of decision making are constrained by the need to explain the following behavioral phenomena: risk aversion, gambling, purchases of insurance, investment, the paradoxes of Allais and Ellsberg, intransitivity of preference, irregularities of choice, preference reversals, risk judgments, violations of branch independence, the difference between buying and selling prices, viol...

Nature , custom , and stipulation in the semiotic of John Poinsot

A fundamental fact of human existence is that we have no access to nature or to another mind, or even to our own mind, except through signs. Our cognition of the external world is always mediated by perceptual and conceptual signs, just as our social relations are always mediated by linguistic and gestural signs. As Deely says (1988: 31): There is nothing in thought or in sensation which was no...
