In this paper, a new guidance law is designed to improve the performance of a homing missiles guidance system in terminal phase. For this purpose first of all, the two dimensions equations of motion are formulated, then the approximation dynamic of missile control loop is added to these equations which are nonlinear whit unmatched uncertainty. Then, a new adaptive back-stepping method is develo...

This paper presents a context-aware guidance and messaging system for large buildings and surrounding venues. Smart Signs are a new type of electronic doorand way-sign based on wireless sensor networks. Smart Signs present in-situ personalized guidance and messages, are ubiquitous, and easy to understand. They combine the easiness of use of traditional static signs with the flexibility and reac...

conclusions the sophistication of electronic prescription and integration with ehr will become a reality, if all its stakeholders collaborate in developing fast and secure electronic prescription systems. it is plausible that the required infrastructure should be provided for implementation of the national integrated electronic prescription systems in countries without the system. given the bar...

Electronic Orientation Aids (EOA) usually guide visually impaired pedestrians using turn-by-turn instructions. However, several studies have demonstrated that mental representations of space seem difficult to build when turn-by-turn instructions only are provided. This is a crucial point as getting an accurate spatial representation of the surroundings can make the difference between successful...
