The positivity preserving property for the biharmonic operator with Dirichlet boundary condition is investigated. We discuss here the case where the domain is an ellipse (that may degenerate to a strip) and the data is ...
In 1976 Procesi and Schacher developed an Artin–Schreier type theory for central simple algebras with involution and conjectured that in such an algebra a totally positive element is always a sum of hermitian squares. In ...
Ostrowski showed that there are intimate connections between the gap structure of a Taylor series and the behaviour of its partial sums outside the disk of convergence. This paper investigates the corresponding problem for ...
Herein a two stage Kalman filter based algorithm is proposed for processing of Inertial Measurement Unit (IMU) data to obtain accurate position estimation over a short period of time. The proposed algorithm uses a novel ...
We survey some work concerned with small universal Turing machines, cellular automata, tag systems, and other simple models of computation. For example it has been an open question for some time as to whether the smallest ...
This paper presents data on single pregnant women's encounters
in public in an Irish context. Data were collected using in-depth
interviews, which were analysed using a grounded theory
strategy. The study was conducted ...
Annual Irish data are used to estimate a model which allows for the joint determination of commodity demands and labour supply. Consumer preferences are modelled by a cost function of the Gorman polar form which permits ...
Based on a qualitative study of non-marital pregnancy and childbearing in the Republic of Ireland, this article reports on the gendered power position of unmarried women who return to their parental homes following their ...
Many recent approaches to modeling social networks have focussed on embedding
the actors in a latent “social space”. Links are more likely for actors that are
close in social space than for actors that are distant in ...
Do people care more about the environment as their income increases? In this paper we use micro data to tackle this question in two different ways. We first look at the correlation between income and attitudes towards the ...
