Abstract: Preventive maintenance is early access or pre-planned maintenance of the problems occur in any machinery units and it has become the important part of today’s industry to avoid breakdown as it can save costly faults, keep Continues production with standardize machinery, reduce waste and also important for safety of deployment. The paper describes the way to avoid breakdown in CNC’s by using time based scheduled preventive maintenance for different parameters, while taking 20 CNC machines under observation. PM sheet of CNC’s is divided into parts over time for different parameters like chuck pressure inspection is kept in daily basis list while ATC Arm in 4 month check list. Some parameters set on the basis of theoretical studies of material fatigue life and some on experimental basis in the resultant sheet. The developed sheet could help manufacturers to figure out the problems in CNC’s on their usage over time range, simply the sheet can be taken as survey of performance of CNC’s. Also a proper planed PM sheet can save a valuable amount of money on maintenance.

Abstract: The people around the world live a safe life due to the sacrifices of the brave soldiers, in order repay the favor, so we must shield them from risks due to they face in the warfare by equipping them with advanced technology. Equipping people especially soldiers to guarantee the security of the state and its stability. Terrorism in a lot area around the world (Sinai Peninsula that is considered one of the dangerous area) is represented threat on people life. This work designed smart monitoring system for soldiers who protecting the homeland so, it is necessary to help them by using smart monitoring system to avoid any terrorist attack or know their places when the abduction of any one of these soldiers. Supply soldier with modern technological devices makes it easy for us to know the health status and their location and this makes the control rooms in the military full-time to monitor the enemy rather than preoccupation with monitoring soldiers. Wireless communications devices play an important role in monitoring the soldiers through the use of the devices Global Positioning System (GPS) system, and also SOS messages that help the soldier to adapt with different situation. All the data collected from the sensors and send to the web server to make analysis also statistics depending on these information Base Stations can make the right decision and send it to the soldier to follow thanks to this smart control system.

Abstract: Embedded real-time systems are combinations of hardware and software fully integrated into the systems they control. Due to the continuous technological evolution in the hardware and software and the diversity of the targeted areas of application, these systems have become omnipresent in our professional and personal lives. Thus, various approaches based on model driven engineering (MDE) have been proposed in order to control the inefficiency of the methods of their current design. Each of these approaches has its own meta-model and its corresponding UML profile, specialized or adapted to a particular category of these systems. Indeed, in this paper we will propose a generic meta-model, taking advantage of a large number of these meta-models, which can be adapted to the majority of embedded real-time systems.
