We propose an illumination strategy for interferometric imaging that allows for robust depth recovery from intensity-only measurements. For an array with colocated sources and receivers, we show that all the possible interferometric data for multiple sources, receivers and frequencies can be recovered from intensity-only measurements provided that we have sufficient source location and frequenc...

BACKGROUND some cohort studies of ageing and health supplement questionnaire-based surveys with in-home measurements of biological parameters and others have required respondents to attend assessment centres. Centre-based assessments facilitate detailed measurements and novel technologies, but may differentially influence participation. The aim of this paper is to compare the characteristics of...

Conversational technologies such as email, chat rooms, and blogs have made the transition from novel communication technologies to powerful tools for learning. Currently virtual worlds are undergoing the same transition. We argue that the next wave of innovation is at the level of the computer interface, and that mixed-reality environments offer important advantages over prior technologies. Thu...

HOUSTON H . CARR, Ph.D, PE, is an Assistant Professor of Management (MIS) in the College of Business Administration at The University of Georgia. Before completing his doctorate in information systems, he spent twenty-one years in industry, the last nine of which were active in analysis, design, and consulting in the area of computer-based pricing and proposal monitoring systems. His research i...

With the emergence of video on community media sites such as YouTube or TED, there is a need to understand interactions by community participants around video in order to maximise the potential of these systems to support communities and create meaningful interactions online. In this paper, we illustrate how ethnomethodologically-informed studies of the social interactions among a small group o...

Recent advancements in sequencing technology have made it possible to study the mechanisms of gene regulation, such as protein-DNA binding, at greater resolution and on a greater scale than was previously possible. We present an expectationmaximization learning algorithm that identifies enriched spatial relationships between motifs in sets of DNA sequences. For example, the method will identify...

In this paper an interactive game is described, that has been developed for a company using new technologies for raising awareness at job fairs. An already existing framework of a game terminal for job fairs is used. The corporate identity, the content of the advertised job, but also the attraction of a young and technologically interested audience is combined in a game in order to develop an i...
