Thermoelectric energy harvesting using vapour chamber coolers for aerospace applications
No full textThermoelectric generators (TEGs) have shown great potentials to supply low-power sensor nodes in aerospace applications due to their relatively small size, adequate output power and reliability. TEGs convert waste heat available at aircraft locations into a usable potential difference. However, TEGs’ performance greatly depends on the use of passive cooling systems such as heatsinks to enhance their energy supply. This paper reports the first proof-of-concept use of vapour chambers coupled to traditional circular pin-fin heatsinks to enhance the output power of TEGs. Vapour chambers are compact and small capillary-driven heat spreaders that incorporate a cavity in their volume containing a working fluid to provide a high effective thermal conductivity. Numerical simulations and experimental tests revealed that the use of vapour chambers provided significant increase of the output power, with a maximum produced power of 28.2 W and a relative difference of 6.27 W against conventional energy scavenging configurations. Results demonstrate the high thermal cooling performance of vapour chambers to efficiently support thermal energy harvesting solutions designed for condition and structural health monitoring
The demand for commodity insurance by developing country agricultural producers - theory and an application to cocoa in Ghana
No full textThe author considers the benefit to agricultural producers of commodity price insurance that provides in every year-but in advance of the resolution of production and price uncertainty-a minimum price for a fixed or variable portion of production. Under the assumption that producers do not change their long term production and income diversification pattern, the author suggests a theoretical framework that leads to explicit formulas of the benefit in providing this type of insurance. He shows that this benefit depends not only on the actuarially fair insurance premium, but also on household-specific factors that depend on the attitudes to risk, the consumption smoothing parameters, and the household-specific exposures to income risks. The author applies the theoretical framework for Ghana, using the Ghana Living Standards Survey data to specify various classes of cocoa-producing households and monthly price data for both domestic and international prices, to formulate appropriate models for ascertaining price risks faced by producers. The author gives empirical estimates of the actuarially fair premium, and shows that they are smaller than market-based put option prices from organized exchanges. The overall benefit in providing minimum price insurance to households, however, turns out to be substantially higher than the actuarially fair premiums and the market-based put option prices. This is due to both the magnitude of the uncertainties facing the households, as well as their risk and consumption smoothing behavior.Labor Policies,Environmental Economics&Policies,Health Economics&Finance,Economic Theory&Research,Payment Systems&Infrastructure,Environmental Economics&Policies,Economic Theory&Research,Health Economics&Finance,Insurance&Risk Mitigation,Services&Transfers to Poor

The Author of the Alexander Romance
No full textThis paper, which is based on a portion of the introduction of the author’s edition of Il Romanzo di Alessandro (Mondadori: Fondazione Valla 2007), surveys the generic components of the Alexander Romance in an attempt to arrive at a definition of the work. The argument builds on Merkelbach’s categorisation of elements and uses Fusillo’s insight into the novel as an ‘encyclopaedic genre’ to propose that ‘historical novel’ is not, as Hägg contended, a misnomer for the work. The main components I discuss are: ‘life’; praxeis; chreiai; Cynic elements, including choliambic poetry and utopian perspectives; and the Egyptian aspects of the narrative. A concluding jeu d’esprit offers a characterisation of the putative author, his antecedents and his process of composition.Richard Stoneman was for 25 years editor for classics at Croom Helm and then Routledge. In 1997 he was appointed an Honorary Fellow in the department of classics, University of Exeter. After retiring from publishing in 2006 he has been pursuing his researches on the Alexander legends and teaching a course on the subject at Exeter. His Penguin translation of the Alexander Romance was published in 1991, and a volume of translated Legends of Alexander the Great appeared from Everyman in 1994. Also in 1994 he co-edited Greek Fiction with John Morgan. His edition of the Greek recensions of the Alexander Romance was published (volume I) by the Fondazione Valla in 2007 – volumes II and III will follow over the next few years – and his Alexander the Great: A Life in Legend appeared from Yale University Press in spring 2008. He is the author of a number of other books on Greek history and travel, and is writing a book on oracles
