Pervasive Healthcare – i.e. designing pervasive computing technologies for healthcare usage – is an especially promising area within pervasive and ubiquitous computing research. However, it is extremely difficult to evaluate such systems because establishing clinical evidence for medical benefits would require longitudinal, randomized, doubleblind, placebo-controlled trials involving a homogene...

New computer-based writing environments are being developed which combine a hypertext ‘ideas organiser’ with a text editor. We compare two algorithms which could be used in such environments for turning networks of notes representing ideas into linear draft documents. The algorithms treat the notes network as a directed, labelled graph and they are designed to produce a linear ordering of the n...

We completely solve the problem of enumerating combinatorially inequivalent d-dimensional polytopes with d + 3 vertices. A first solution of this problem, by Lloyd, was published in 1970. But the obtained counting formula was not correct, as pointed out in the new edition of Grünbaum’s book. We both correct the mistake of Lloyd and propose a more detailed and self-contained solution, relying on...

September 2011 this is a rough and incomplete first draft please do not distribute or quote Abstract: Recent theoretical work has demonstrated that holdout is the appropriate efficiency justification for eminent domain. In parallel, recent empirical work has demonstrated that state legislatures either grant discretion to local authorities, or constrain them from using eminent domain. This paper...

In recent past, the connection between aspects of top level athletes’ careers and success in top-level sport range was focussed by a sociological based theory of training in sports. Several studies showed, that simply structured connections between training in top level sports and success are far from being able to explain the emergence of success in sport in collectives from processes of indiv...

Charmonium is an attractive system for the application of lattice QCD methods. While the sub-threshold spectrum has been considered in some detail in previous works, it is only very recently that excited and higherspin states and further properties such as radiative transitions and two-photon decays have come to be calculated. I report on this recent progress with reference to work done at Jeff...

Little research has been conducted to investigate highly advanced ESL learners’ written production of suggestions when addressing interlocutors of lower social power. The present study fills this gap by examining non-native speaking (NNS) composition instructors’ pragmatic choices of suggestions as compared to those made by their native speaking (NS) counterparts when providing written feedback...

The paper defines a simple tâtonnement process of adjustments in prices and quantities, where excess demand results in nominal price increases and excess supply results in quantity rationing of supply at unchanged prices. Under reasonable assumptions, the process converges to a supply-constrained equilibrium. The result contributes to our understanding of how supply-constrained equilibria come ...
