A relationship among language, gender, and discourse genre has previously been observed in informal, spoken interaction and formal, written texts. This study investigates the language/gender/genre relationship in weblogs, a popular new mode of computer-mediated communication (CMC). Taking as the dependent variables stylistic features identified in machine learning research and popularized in a ...

On 1-4 June 2003, the Danish Institute of Agricultural Sciences (DIAS) hosted the International Symposium on Gaseous and Odour Emissions from Animal Production Facilities. This symposium can be considered a follow-up of the first special symposium on gaseous and odour emissions, held in 1997 in Vinkeloord, the Netherlands (Voermans and Monteny, 1997). The organizers of the 2003 symposium were S...

The aim of this set of exercises is to build up experience in developing Bayesian networks for realistic clinical problems. The exercises included in this assignment learn you something about the relationship between consulting Bayesian networks, using tools such as SamIam or Genie (See below), and problem solving. We start by describing two software tools for building Bayesian networks by hand...

For any given short code (referred to as the basic code), block Markov superposition transmission (BMST) provides a simple way to obtain predictable extra coding gain by spatial coupling the generator matrix of the basic code. This paper presents a systematic design methodology for BMST systems to approach the channel capacity at any given target bit-error-rate (BER) of interest. To simplify th...

447 This discussion paper surveys the current state of software for scientific and engineering applications, and the foreseeable evolutions. It argues that a serious change in the attitude of scientists and engineers is necessary in order to master the growth of problem size. The discussion includes aspects of methodology, tools and languages ; we feel that much progress is needed in all three ...

If mobile computing is to become the predominant computer usage paradigm in the coming years as is widely anticipated, a substantial increase in the demand for mobile computing applications and services will arise. How best to engineer such applications remains an open question and is naturally the focus of much research. In this article, we propose the use of intelligent agents as the constitu...

We have extended the 3-D ocean based “Grid ENabled Integrated Earth system model” (GENIE-1) to help understand the role of ocean biogeochemistry and marine sediments in the long-term (∼100 to 100 000 year) regulation of atmospheric CO2, and the importance of feedbacks between CO2 and climate. Here we describe the ocean carbon cycle, which in its first incarnation is based around a simple single...

The time needed to apply a hierarchical clustering algorithm is most often dominated by the number of computations of a pairwise dissimilarity measure. Such a constraint, for larger data sets, puts at a disadvantage the use of all the classical linkage criteria but the single linkage one. However, it is known that the single linkage clustering algorithm is very sensitive to outliers, produces h...

BACKGROUND The presence of dual HIV-1/HIV-2 infection in Ghana and the different drug requirements for the treatment of HIV-1 and HIV-2 presents difficulties for the treatment of dual infections with both viruses. OBJECTIVES To determine the prevalence of the dual sero-positive profile in treatment naive patients at a principal ART Clinic in Accra, Ghana and to investigate if rapid screening ...

In this paper, we discuss the capacity region of the deterministic Y-channel with private and common messages. Each user aims to deliver two private messages to the other two users in addition to a common message directed towards both of them. As there is no direct link between the users, all messages must pass through the relay. We present outer-bounds on the rate region using genie aided and ...
