On 15th May of  2012 named by A. Alikhanyan National Labaratory aspirant's, A. Hovhannisyan's  dissertation defense of the candidature of science degree of physics and mathematics was held. The theme of the thesis was called  "The research of  secondary cosmic ray modulation effects and the creation of possible radiation storms alert system". The aspirant supervisor was professor Ashot Chilingaryan. The opponents were N. Akopov and A. Toneyan.

The dissertation was devoted to the research of flows modulation effects of secondary cosmic rays and to the alert signal system creation of the Aragats scientific research station by the detector data received from the radiation storms. 

The main goals and completed works are:
  • The creation of the alert signal system from radiation storms
  • To calculate the possibility of alert system effectiveness and of wrong alert 
  • The application of the detectors of the Aragats research station as well as of time series filtration algorithm  of multivariate detectors. The enhancement research of particles flows during the thunderstorm. 

There was also a reference to the suggestion of the cosmic weather, to the modern research methods and to the existing foreseeing methods.   
The opponent has highly appreciated the aspirant work and mentioned that the work was done at the highest scientific level and it was an independent scientific research and consisted of new scientific results. He also expressed a wish that the aspirant continued the research on the selected theme and reached rather bigger successes in his chosen field.
