Deriving the Derivative

open access: yesSigns and Society, 2018
AbstractThe anthropology of finance has been dominated by ethnographic field research and the performativity thesis advanced by Donald Mackenzie and Michel Callon. This essay takes a different tack and proposes a semiotic framework to look at the central concept in derivative finance, that of volatility.

Solving Parabolic Partial Delay Differential Equations Using The Explicit Method And Higher Order Differences

open access: yesJournal of Kufa for Mathematics and Computer, 2013
In this paper we use the higher order differences for second order (derivative)  in solving  parabolic partial delay differential equations by using the explicit method and we get results are more closer to the exact values than the results which can ...

Derivative chameleons [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2012
We consider generalized chameleon models where the conformal coupling between matter and gravitational geometries is not only a function of the chameleon field , but also of its derivatives via higher order co-ordinate invariants. Specifically we consider the first such non-trivial conformal factor A( ,X), where X is the canonical kinetic term for
