Models and muddles: comment on ‘Calibration of agricultural risk programming models using positive mathematical programming’

open access: yesAustralian Journal of Agricultural and Resource Economics, 2022
There is an emerging strand in the agricultural economics literature which examines the calibration of risk programming models using the principles of Positive Mathematical Programming (PMP). In a recent contribution to this journal, Liu et al. (2020) compare three different PMP approaches and attempt to find the ‘most practical’ method for calibrating

Programming pulse width dependent charge retention characteristics of low-power synaptic thin film transistors [PDF]

open access: yesScientific Reports
A study on a programming-pulse width dependent synaptic characteristics of a sub-threshold operating hafnium doped zinc oxide (Hf-ZnO) thin-film transistor (TFT) is presented. For this, the static and pulsed characteristics of fabricated Hf-ZnO TFTs need

Positive Mathematical Programming with Generalized Risk [PDF]

open access: yesSSRN Electronic Journal, 2014
Price risk in a mathematical programming framework has been confined for a long time to a constant risk aversion specification originally introduced by Freund in 1956. This paper extends the treatment of risk in a mathematical programming framework along the lines suggested by Meyer (1987) who demonstrated the equivalence of expected utility and a wide
