10 Jul 2006TL;DR: This paper describes how the plans of the enemy are built up so that their intended effects are achieved and discusses the need for including termination states in the plan recognition method and ontologies aimed to support the construction of the Bayesian networks needed for capability-based plan recognition.
Abstract: The new types of opponents and new kinds of situations that the Swedish defence forces are facing today calls for new information fusion methods. In order to provide commanders with the ability to predict the enemy's future actions, tools for automatic plan recognition are needed. In this paper, we take the first step towards constructing such a method based on recognizing plans using information about the capabilities of the enemy. The method combines our previous work on plan recognition using bayesian networks based on comparing enemy movements to their doctrines and methodology for force aggregation using capabilities. We describe how the plans of the enemy are built up so that their intended effects are achieved. The relations between these, their resources and the context in which they are acting are used to construct the plan recognition network. We discuss the need for including termination states in the plan recognition method and describe ontologies that are aimed to support the construction of the bayesian networks needed for capability-based plan recognition. We conclude with a discussion of possible extensions of the method.

TL;DR: In this article, the fatigue behavior of single overlap mechanically fastened aluminium joints tested in the FALSTAFF spectrum was investigated, and the overall test results indicated that the friction wear between the joint parts significantly affected the fatigue behaviour of the inspected joints.

TL;DR: By investigating the group of people in a systematic way with different K values, analyze cluster density, cluster quality and changes in cluster shape, the unsupervised K-means clustering and the semi-supervised hidden Markov model can automatically detect anomalous motion patterns.
Abstract: We investigate the unsupervised K-means clustering and the semi-supervised hidden Markov model (HMM) to automatically detect anomalous motion patterns in groups of people (crowds). Anomalous motion patterns are typically people merging into a dense group, followed by disturbances or threatening situations within the group. The application of K-means clustering and HMM are illustrated with datasets from four surveillance scenarios. The results indicate that by investigating the group of people in a systematic way with different K values, analyze cluster density, cluster quality and changes in cluster shape we can automatically detect anomalous motion patterns. The results correspond well with the events in the datasets. The results also indicate that very accurate detections of the people in the dense group would not be necessary. The clustering and HMM results will be very much the same also with some increased uncertainty in the detections.

TL;DR: This novel assay provides a powerful tool for diagnosis of hantaviruses from different clades and regions and may also be useful in surveys with the purpose of finding new hantviruses in rodent or insectivore species.
