No full textFractal Dimension Logarithmic Differences Method for Low Voltage Series Arc Fault Detection
No full textSeries arc faults introduce singularities in the current signal and changes over time. Fractal dimension can be used to characterize the dynamic behaviour of the current signal by providing a degree of signal chaos. This measure of irregularity exhibits changes in signal behaviour that can suitably be used as a basis for series arc fault detection. In this paper, an efficient low voltage series arc fault detection method based on the logarithmic differences of the estimate of the fractal dimension of the current signal using the multiresolution length-based method is presented. The discrete wavelet transform and the hard thresholding denoising with the universal threshold are also used. Experimental results in both normal and arcing condition with different loads in compliance with the standard IEC 62606 show the effectiveness of the method that allows reliable series arc fault detection within 80ms
A novel procedure for medial axis reconstruction of vessels from Medical Imaging segmentation
Full text linkA procedure for reconstructing the central axis from diagnostic image processing is presented here, capable of solving the widespread problem of stepped shape effect that characterizes the most common algorithmic tools for processing the central axis for diagnostic imaging applications through the development of an algorithm correcting the spatial coordinates of each point belonging to the axis from the use of a common discrete image skeleton algorithm. The procedure is applied to the central axis traversing the vascular branch of the cerebral system, appropriately reconstructed from the processing of diagnostic images, using investigations of the local intensity values identified in adjacent voxels. The percentage intensity of the degree of adherence to a specific anatomical tissue acts as an attraction pole in the identification of the spatial center on which to place each point of the skeleton crossing the investigated anatomical structure. The results were shown in terms of the number of vessels identified overall compared to the original reference model. The procedure demonstrates high accuracy margin in the correction of the local coordinates of the central points that permits to allocate precise dimensional measurement of the anatomy under examination. The reconstruction of a central axis effectively centered in the region under examination represents a fundamental starting point in deducing, with a high margin of accuracy, key informations of a geometric and dimensional nature that favours the recognition of phenomena of shape alterations ascribable to the presence of clinical pathologies
The systemic approach in sustainable environmental planning: References to the ecology of living systems
Full text linkThe article investigates the possibility of adopting indicators and analytical methods characteristic of the living systems ecology to understand different territorial metabolism phenomena. In addition to explore and orient deep sustainability processes in the transformation of the urban fabric, supporting a circular and self-sustaining economic model. The interpretation of the horizontal / vertical theme is twofold: on one hand, the material substrate of the design process is observed by a high level, such as enabling to grasp systemic connections necessary to eco-environmental scale; on the other hand, the construction of interactive networks promotes the emergence of new configurations in decision-making processes. The in-depth analysis of the analytical tools applied to natural metabolic processes combines the choice of horizontal or vertical physical configuration to achieve the following objective: maximizing the work obtainable (ie. the service provided to live, feed and move) with the same solar energy used. This constitutes the main law that regulates the evolution of natural terrestrial ecosystems (Odum, 1996) and represents the fundamental criterion for defining profound sustainability in the planning / design production processes of the built environment (Daly, 2008)
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
