Morphological pattern spectra computed from granulometries are frequently used to classify the size classes of details in textures and images. An extension of this technique, which retains information on the spatial distribution of the details in each size class is developed. Algorithms for computation of these spatial pattern spectra for a large number of granulometries on binary images are pr...

Article history: There exist rich cooperative behaviors and their transitions in biological neuronal systems as some key biological factors are changed. Among all of cooperative behaviors of neuronal systems, the existing experiments have shown that the spatiotemporal pattern and synchronization dynamics are very crucial, which are closely related to normal function and dysfunction of neuronal ...

Understanding the self-regulatory mechanisms controlling the spatial and temporal structure of multicellular organisms represents one of the major challenges in molecular biology. In the context of plants, shoot apical meristems (SAMs), which are populations of dividing, undifferentiated cells that generate organs at the tips of stems and branches throughout the life of a plant, are of particul...

Abstract: The spatial pattern analysis can be used to discover the distribution of people’s behaviors in space. Traditional spatial pattern analysis does not consider the decision making process of human activities. This paper presents two adjusted spatial choice models that include models of decision-making process. These new adjusted spatial choice models are applied to detect the spatial pat...

Based on the habituation mechanism found in biological neural systems, novel dynamic neural networks are proposed for recognizing temporal patterns. The speciic task considered in this paper is the classiication of whale songs from passive SONAR data, but the networks are also readily applicable to other temporal pattern recognition problems. The fact that the networks designed operate dynamica...

Design, and in particular the design of the built environment in which we live and work, is an enterprise about which it is surprisingly difficult to talk. Part of the problem is that the right words don’t exist to discuss an activity which seems at once to be highly personal, but whose product is public and, preeminently among the arts, social in its intent. However, if we look at the way that...

This paper proposes an online segmentation scheme for broadcasted American football TV programs. The TV video streams are online partitioned into a series of play-break patterns with a relatively short delay. All the detected plays form an event-based summarization which contains complete information about the original match. The main contributions of the proposed scheme are twofold. First, an ...

This paper proposes a methodological framework to analyze the activity and travel pattern of workers during the evening commute. The framework uses a discrete-continuous econometric system to jointly model the decision to participate in an activity during the evening commute and the following attributes of the participation: activity type, activity duration, and travel time deviation to the act...

In the early stages location theory mainly concentrated on the spatial pattern of industrial activities. Although the focal point of theoretical considerations and empirical analysis has shifted towards the service sector in the meantime, the location of knowledge-based activities has not yet been explained in a satisfying way. Especially the spatial dimension of innovation processes needs furt...

When a reinforcement is delivered according to a fixed-ratio schedule, it has been found that responding occurs in a specific temporal pattern (Ferster & Skinner, 1957). Periods of no responding characteristically follow the delivery of the reinforcer. Once responding begins, it assumes a very high rate of several responses per second. The resulting performance is bivalued; responding occurs ei...
