Nowadays, international and national events clearly point out the need for cooperation between different defense organizations in crisis and emergency situations (disaster events, migration issues, and other emergencies) for successful tasks. The fundamental basis of this cooperation is always the command and control activity supported by modern technical equipment that ensures the coordinated implementation of tasks. The key, human element of info-communication support is the preparation and training of the successful professionals. In this paper, the authors intend to present the importance of vocational training.

Nowadays the Romanian Armed Forces are subject to a process of modernization of the defence capabilities, and the process is mainly focussed towards the military assets. However, the human factor is decisive in manipulating the new military technology in accordance with its technical specification. In this context we assess that the process of ensuring the proper human resource is a vulnerability factor, and therefore we tackled the demographic decline as a threat for our national security, as it has been less studied in the last period of time. Considering this social phenomenon as one of great importance for our national security, we conducted a research that would lead to pertinent conclusions regarding the trend of the demographic decline and would provide solutions to increase the number and the quality of human resource selected for the military system.

An HVAC system contains heating, ventilation and air conditioning equipment used in office or industrial buildings. The goal of this research is to design a controller for the process of cooling an office building that is made up of three rooms. The desired room temperature can be achieved by controlling the fans making up the fan coil units and the cooling medium’s temperature. By these means the building connected to the electrical grid becomes a smart office. The used building model includes several dynamically changing interior and exterior heat sources affecting the inner climate, which introduces a level of uncertain prediction into the system. We have determined the controller’s performance by the rate of deviation from the expected temperature, the consumed electrical energy and the generated noise. The controller was created in Matlab Simulink with the possibility of migration to a Siemens PLC.
