In the surveillance of interested regions by unmanned aerial vehicle (UAV), system performance relies greatly on the motion control strategy of the UAV and the operation characteristics of the onboard sensors. This paper investigates the 2D path planning problem for the lightweight UAV synthetic aperture radar (SAR) system in an environment of multiple regions of interest (ROIs), the sizes of w...

Unmanned Airborne Vehicles (UAVs) today are designed for specific applications in mind, with the majority of UAV applications being focussed on reconnaissance-type missions, reflecting the large military interest in the platform. While a UAV usually is much cheaper than a military attack or surveillance aircraft, the cost of constructing, running and maintaining a UAV is often beyond what civil...

In future mobile networks, it is difficult for static base stations (BSs) to support the rapidly increasing data services, especially for cell-edge users. Unmanned aerial vehicle (UAV) is a promising method that can assist BSs to offload the data traffic, due to its high mobility and flexibility. In this paper, we focus on the UAV trajectory at the edges of three adjacent cells to offload traff...

This paper introduces the Agile and Virtual University (UAV) model for continuing education and training, which, supported by a Market of Teaching Resources and a broker, promotes the matching between the ‘offer’ of units of learning and the ‘demand’ of individualized learning projects. The answer to the particular and specific needs of each learner is provided through a network of resources pr...

Human errors are responsible for 67.57% of accidents in one hundred years of aviation history (1905-2005). UAV technology was developed to eliminate human limitations and reduce chances of human factor in accidents. However, this experiment proved to be questionable, as the statistics show higher number of accidents involving human errors in unmanned systems. The aim of study is to determine ca...

For multimulti-unmanned aerial vehicle (UAV) air combat decision problems, this paper proposes a multi-UAV task allocation method based on cloud model. Firstly, we analyses air combat situation advantage of random and fuzzy information. The cloud model is applied to multi-UAV task allocation. We establish air combat superiority index model based on cloud model. And then through comprehensive cl...

This chapter presents an overview of linear flight control and guidance methods for Unmanned Aerial Vehicles (UAVs). The chapter begins with a discussion of rotation matrices and kinematic equations of a UAV. The six-degree of freedom UAV equations of motion are also derived using rigid body dynamics principles. The equations of motion are then linearized and several linear multi-loop closure t...

Complex UAV systems, due to the high cost and the risks associated with their development become a prime candidate for the adoption of systems engineering methodologies. A successful UAV designer needs not only a good understanding of design, but also systems engineering approach. The design of a UAV begins with the requirements definition and extends through functional analysis and allocation,...

Phenotyping plays an important role in crop science research; the accurate and rapid acquisition of phenotypic information of plants or cells in different environments is helpful for exploring the inheritance and expression patterns of the genome to determine the association of genomic and phenotypic information to increase the crop yield. Traditional methods for acquiring crop traits, such as ...

At first glance, most aspects of border protection activity look like classical examples of zero-sum games, in which the interests of the two sides are exactly opposite. This is how such situations are planned now: this is how border patrol agents are assigned to different segments of the border, this is how routes of coast guard ships are planned, etc. However, there is a big difference betwee...
