A reformulation of the dual control problem makes it possible to interpret and understand the nature of different approximations to dual control, in particular the Adaptive Predictive Controller (APC) and the Active Suboptimal Dual Controller (ASOD). The analysis makes the origin of the computational problems more clear, and suggests new alternatives for approximations.

We have computed the quark anti-quark expectation value in finite volume at two loop in chiral perturbation theory and compare it with a formula obtained in analogy to the Luscher formula for pion mass in finite volume. We observe that due to the small finite size correction at two loop it is not possible to obtain conclusions on the accuracy of the extended Luscher formula

Abstract This paper addresses the importance of networks for entrepreneurs in bankruptcy, based on interviews with entrepreneurs who have experienced at least one bankruptcy. Analysis of the interviews reveals two discursive themes: entrepreneurship and bankruptcy. Entrepreneurship is expressed in terms of initiative and of contacts in business contexts; bankruptcy concerns economic marginalizatio

One of the instances that have often been suggested as a possible link between Indo-European and biblical traditions and thought constructs is that of the battle against the dragon or sea monster – a special instance of the Chaoskampf motif. Suggestions in this direction have been put forth by Nicolas Wyatt and by Ajoy Kumar Lahiri, who have argued that Semitic traditions concerning the divine bat

This paper presents narrowband path loss measurements carried out at the 5.1 GHz band. The focus has been on building-shielding loss in office-building areas. Both azimuth and elevation dependence have been studied. The measurement campaign was performed in a multi-storey building on three different floors in an indoor office environment. A helicopter was used to simulate a mobile satellite system

Many analyses and debates developed in the last decades around trade unions’ revitalisation, pointing to different national traditions in the varieties of capitalism. Gender equality adds a new perspective to these debates, showing that women can be a crucial test for, and an instrument of, trade union revitalisation. In the current situation in Italy, what are the main challenges facing working w

One of the most significant political changes over the past 25 years in Tamil Nadu, as elsewhere in India, is the implementation of a statutory status for a local elected government in accordance with the 73rd and 74th amendments to the Constitution passed by the Indian Parliament in 1993. The performance of the new system in Tamil Nadu is rather average and not very vibrant. Nevertheless, it has
