This paper studies interference alignment scheme and minimum mean square error (MMSE) improvement in Internet of Things (IoT)-oriented cognitive systems, where IoT devices share the licensed spectrum by cognitive radio in spectrum underlay. Target to manage the inter-tier interference caused by cognitive spectrum sharing as well as ensure an MMSE at receivers, the interference alignment algorit...

Precision Agriculture (PA) is an approach to maximizing crop productivity in a sustainable manner. PA requires up-to-date, accurate and georeferenced information on crops, which can be collected from different sensors ground, aerial or satellite platforms. The use of optical thermal Unmanned Aerial Vehicle (UAV) platform emerging solution for mapping monitoring PA, yet many technological challe...

the six-degree equations of flight in their classic form do not provide a proper physical perception due to a number of interferences. nor do they render visible the important role of attack angles. in this study, attempts have been made to develop a complete set of 3d acceleration equations from the equations of normal and tangential acceleration αn=vωv, αt=v ̇. for this purpose, a coordinate s...

Autonomous unmanned aerial vehicle (UAV) landing can be useful in multiple applications. Precise is a difficult task because of the significant navigation errors global positioning system (GPS). To overcome these and to realize precise control, various sensors have been installed on UAVs. However, this approach challenging for micro UAVs (MAVs) strong thrust forces are required carry sensors. I...

Learning to fly an aircraft is a complex task that requires the development of control skills and goal achievement strategies. This paper presents a behavioural cloning system that learns to successfully fly manoeuvres, in turbulence, of a realistic aircraft simulation. A hierarchical decomposition of the problem is employed where goal settings and the control skill to achieve them are learnt. ...

Because the amount of fuel usage is huge, and exhaust emissions of commercial transports is regulated under the Kyoto Protocol, how to reduce fuel consumption is an urgent problem for all airlines. The airlines urgently need a practical method to reduce fuel consumptions within constraints to accomplish the mission. The objective for the present paper is to use a model-based method and flight d...
