A comparative study of the use of large margin classifiers on seismic data

In this work we present a study on the analysis of a large data set from seismology. A set of different large margin classifiers based on the well-known support vector machine (SVM) algorithm is used to classify the data into two classes based on their magnitude on the Richter scale. Due to the imbalance of nature between the two classes reweighing techniques are used to show the importance of reweighing algorithms. Moreover, we present an incremental algorithm to explore the possibility of predicting the strength of an earthquake with incremental techniques.

A List Sequential Sampling Method Suitable for Real-Time Sampling

Abstract.  A flexible list sequential π ps sampling method is introduced and studied. It can reproduce any given sampling design without replacement, of fixed or random sample size. The method is a splitting method and uses successive updating of inclusion probabilities. The main advantage of the method is in real-time sampling situations where it can be used as a powerful alternative to Bernoulli and Poisson sampling and can give any desired second-order inclusion probabilities and thus considerably reduce the variability of the sample size.     

Emergent Uses of a Multiplayer Location‐aware Mobile Game: the Interactional Consequences of Mediated Encounters

This case study of the behaviours of players in an advanced location‐aware gaming environment provides a first glimpse of what the experience of living in a mobile‐based augmented urban public space might be like, and of the kind of social order and emergent ‘form‐of‐life’ that might characterize it. We have focused our analyses on three key features. First, game‐related mobility: how users adjust their movements to the ‘augmented’ ecologies that they encounter (augmented with localized informational objects relevant to the ongoing game activity). Second, ‘Onscreen encounters’, which occur when players notice one another's position on their mobile screen. The management of such interactions, where players are open to interaction because their location is a public matter, is a key feature of the construction of the social order in such a location‐aware environment. Third, the management of situations of actual or potential misalignment between ‘ordinary’ and screen‐mediated perceptions. The very possibility of such misalignment is also a peculiarity of location‐aware technologies. These technologies entail collaborative work by the actors to appropriately tame the power relationships that might emerge from such perceptual asymmetries.

Knowledge-based reactive scheduling

Reactive scheduling has emerged as a new concept in production planning and control over the past few years. It is attracting the increased interest of both academic and industrial researchers in developing available knowledge-based techniques in real-time shop floor control applications and providing advanced tools for subsequent industrial applications. In this paper, we provide an overview of research results in the domain of knowledge-based reactive scheduling and some related industrial applications. Since reactive scheduling is a new and not well-defined paradigm, we start by examining some definitions of the problem given by different practitioners in the field. We then examine alternative knowledge-representation technologies and reasoning approaches which, because of t heir flexibility and reactive capability, are often applied in real-time decision-making environments. This is followed by a review of some reported industrial applications, and a summary on major areas for further research, which gives a picture of the width of the gap between the results of current research and their application in practice. Finally, some major trends apparent in the domain are outlined.
