mCLT: an application for collaborative learning on a mobile telephone
2005
Mobile technologies offer new opportunities for distance learning and enable people to collaborate anywhere. This paper introduces an innovative mobile platform for computer-supported collaborative learning in which traditional methodologies of collaboration have been improved, based on 3rd-generation mobile telephones. Students can collect and share live data immediately, anywhere and at any time. This enables them to play an active role in the knowledge-building process. The mCLT is potentially an application for ubiquitous collaborative learning.
A Fuzzy-based Clinical Decision Support System for coeliac disease
2022
Coeliac disease (CD) is a permanent inflammatory disease of the small intestine characterized by the destruction of the mucous membrane of this intestinal tract. Coeliac disease represents the most frequent food intolerance and affects about 1% of the population, but it is severely underdiagnosed. Currently available guidelines require CD-specific serology and atrophic histology in duodenal biopsy samples to diagnose CD in adults. In paediatric CD, but recently in adults also, non-invasive diagnostic strategies have become increasingly popular. In order to increase the rates of correct diagnosis of the disease without the use of biopsy, researchers have recently been using approaches based …
A study of the effect of molecular and aerosol conditions in the atmosphere on air fluorescence measurements at the Pierre Auger Observatory
2010
The air fluorescence detector of the Pierre Auger Observatory is designed to perforin calorimetric measurements of extensive air showers created by Cosmic rays of above 10(18) eV. To correct these measurements for the effects introduced by atmospheric fluctuations, the Observatory contains a group Of monitoring instruments to record atmospheric conditions across the detector site, ail area exceeding 3000 km(2). The atmospheric data are used extensively in the reconstruction of air showers, and are particularly important for the correct determination of shower energies and the depths of shower maxima. This paper contains a summary of the molecular and aerosol conditions measured at the Pierr…
Measurement of the Depth of Maximum of Extensive Air Showers above 10(18) eV
2010
We describe the measurement of the depth of maximum, Xmax, of the longitudinal development of air showers induced by cosmic rays. Almost four thousand events above 10¹⁸ eV observed by the fluorescence detector of the Pierre Auger Observatory in coincidence with at least one surface detector station are selected for the analysis. The average shower maximum was found to evolve with energy at a rate of (106⁺³⁵₋₂₁) g/cm²/decade below 1018.24 ± 0.05 eV and (24 ± 3) g/cm²/decade above this energy. The measured shower-to-shower fluctuations decrease from about 55 to 26 g/cm². The interpretation of these results in terms of the cosmic ray mass composition is briefly discussed.
Potential of the atmospheric monitoring system of JEM-EUSO mission
2009
The existance of high energy particles with energies >1020 eV in the space is a basic problem in fundermental physics, because it means a violation of the GZK theoretical limitation. JEM-EUSO will try to detect such high energy particles in the space by the oprical fluorescence from the high energy paticles incident to the atmosphere. For caliblation of the optical background an atmospheric monitoring system consisting of a spaceborne lidar with an ultraviolet pulsed laser and an IR camera will be used. The IR camera takes images at suitable time intervals, monitoring the cloud cover in the whole field of view (FoV) of the telescope. Moreover stereo images are also taken to retrieve pixel b…
Image segmentation to evaluate islets of langherans
2008
This contribution deals with an unsupervised system to process digital photomicrographs in order to locate and analyze islets of Langherans in human pancreases. The experiment has been conducted on real data and, though we are still going to complete the evaluation of the whole method, we expect to define a set of proper features (e.g. area, perimeter, fractal dimension, shape complexity, texture and entropy) useful for a fast and reliable counting of healthy cells. In particular, this research aims to measure the advisability of a possible implantation in patients affected by type I diabetes mellitus
Proceedings - International Workshop on Computer Architecture for Machine Perception, CAMP
2005
This volume contains the proceedings of the 2005 IEEE International Workshop on Computer Architecture for Machine Perception. CAMP05 is the seventh in the series of workshops which began with CAMP91 in Paris and followed by CAMP93 in New Orleans, CAMP95 in Como, CAMP97 in Boston, CAMP00 in Padova, CAMP03 in New Orleans. The CAMP workshops represent a continuation of the very successful IEEE CAPAMI (Computer Architectures for Pattern Analysis and Machine Intelligence) workshops held during the 1970's and 1980's. Besides the traditional topics of highly parallel architectures, distributed computing, real time systems, VLSI architectures and image analysis algorithms, this edition of the works…
