The proper functioning of the control systems and transportation security has a big impact in the economic process of the country not only by the price of production of these systems, but also for its impact on the environment, human life and bless you. Early detection of faults and critical operations control systems avoids degradation of machinery and safety for citizens.
In this regard, a poster and a scientific paper have involved the presentation of SIDRA ('Smart Identification and Detestion of Radioactive Anomalies' - Detection and Intelligent Identification of Radioactive Anomalies) project during the ninth edition of SAFEPROCESS 2015 (International Symposium on Detection Faults, Supervision and Safety of Technical Processes), held in early September in Paris.
The SIDRA project aims to obtain an improvement in the capacity of detection and identification of illicit trafficking of radioactive materials by sea ports, borders and checkpoints in general, especially in ports and borders. "This is achieved through the application of innovative algorithms and integration of various sources of information to reduce the number of innocent alarms, plus the system itself is designed to support the operator's decision also", explains Luis Felipe Blazquez.
Funded by the European Commission and part of the program Prevention of and Fight against Crime (ISEC), this project has six participating partners: Indra as project leader, Spanish Customs, Valenciaport Foundation, the Politecnico di Milano, the Polytechnic University of Madrid and the University of León (ULE).
SAVE TIME AND MONEY
The work assigned to the ULE in the project has resulted in the development of intelligent algorithms "that can be applied to reduce the number of innocent alarms based on data obtained solely porches (RPMs) Polyvinyl toluene (PVT)" . These frames are used to detect and prevent the entry or exit of radioactive sources in vehicles passing slowly through their detectors.
These detectors panels contain a solvent that polymerizes and produces a solid solution machinable, and sometimes the interpreted information does not distinguish whether the gamma rays generated are from dangerous goods or other types of benign load radioactivity emitted as cat litter, porcelain, stoneware, granite, bananas ... Hence these erroneous alarms which represent over 95% of total detectadas- alarms "cause loss of time and money and you have to inspect cargo with more accurate and more expensive detectors to identify whether it is benign or dangerous goods. "
This entire process is substantially reduced with the research provided by the ULE in SIDRA project. "Our intelligent discrimination algorithms use the limited energy provided by the detectors to automatically decide if the alarm is not hazardous or radioactive source explains Blázquez-; this serves as great supporting staff do not have to re-check the load and thus saving time and money is recorded. "
Luis Felipe Blazquez SIDRA presented the project in the 'Industry Day' symposium by the corresponding poster and through scientific paper 'Classification of Radionuclides on Polyvinyl Toluene Radiation Portal Monitors by a Neural Network Based System', presented as a paper in the session ' Neural Network and Classification Approaches'. Scientific dissemination of the project is complete the above symposium conducted by the ULE in the 19th World Congress of the International Federation of Automatic Control and 22nd IFAC2014 Mediterranean Conference on Control & Automation MED2014.
