Confessions of a Poverty Researcher: My Journey Through the Foothills of Scholarship
Australian Journal of Social Issues, EarlyView.ABSTRACT This paper describes the key events, experiences and ideas that influenced the author's career as a poverty researcher. He describes how his early disillusion with economics was replaced by a spark of interest in social issues and how his migration from the UK to Australia in the mid‐1970s provided the impetus to begin what became a lifetime ...

Study on Natural Gas Decarbonization Process Based on CO2 Desublimation Characteristics
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Natural gas decarbonization is a crucial processing step. In this study, the snow separation technology for removal of carbon dioxide in natural gas based on CO2 desublimation characteristics was introduced. The phase equilibrium calculation of CH4‐CO2 and N2‐CO2 system was carried out by using cubic equations of states (EOSs), and identified ...

Computing generating functions of ordered partitions with the transfer-matrix method [PDF]
Discrete Mathematics & Theoretical Computer Science, 2006 An ordered partition of $[n]:=\{1,2,\ldots, n\}$ is a sequence of disjoint and nonempty subsets, called blocks, whose union is $[n]$. The aim of this paper is to compute some generating functions of ordered partitions by the transfer-matrix method.

Boolean complexes for Ferrers graphs [PDF]
, 2010 In this paper we provide an explicit formula for calculating the boolean number of a Ferrers graph. By previous work of the last two authors, this determines the homotopy type of the boolean complex of the graph. Specializing to staircase shapes, we show
