Theories of shapes are important for object recognition and for reasoning about the behaviour of objects, both tasks strongly constrained by shape. Whereas the extraction of shape properties has extensively been studied in vision, there is still a lack of qualitative shape descriptions which allow reasoning about shapes with AI techniques in a flexible manner. In this paper we present a qualita...

The Qualitative Modelling and Interpretation (QMi) system translates noisy sensor data into a qualitative description of the underlying behaviorof a chemical plant and uses this information together with qualitative models to identify faults and operating regimes. Qualitative models of normal and faulty equipment are simulated to describe the range of possible behaviors in a chemical plant with...

In this paper, we present an approach to qualitative description of images containing non-overlapping 2D objects. This approach consists of extracting the properties of the main points of the objects in an image and applying qualitative models to them. Qualitative models of shape and size describe visual features of the objects in the image, while qualitative models of orientation and distance ...

One key element in the successful dissemination and utilization of qualitative findings is the well-written research report. In contrast to quantitative research, there is no one style for reporting the findings from qualitative research. Qualitative researchers must select from an array of representational styles and formats those that best fit their research purposes, methods, and data. Quali...

Despite nursing's enthusiastic endorsement of the applicability of qualitative research approaches to answering relevant clinical questions, many nurse researchers have been hesitant to depart from traditional qualitative research methods. While various derivations of phenomenology, grounded theory, and ethnography have been popularized within qualitative nursing research, the methodological pr...

The complexity of the atmosphere endows it with the property of turbulence by virtue of which, wind speed variations in the atmospheric boundary layer (ABL) exhibit highly irregular fluctuations that persist over a wide range of temporal and spatial scales. Despite the large and significant body of work on microscale turbulence, understanding the statistics of atmospheric wind speed variations ...
