“…Numerous issues remain unresolved, a part of which are resulted from poorly understood EC-implications [52][53][54][55][56][57][58]. Brain-inspired modelling approach to such implications in the present study majorly depends on amounts of attention data and length of attention time, ignoring the differences in real scenarios.…”

Video surveillance plays a vital role in maintaining the social security although, until now, large uncertainty still exists in danger understanding and recognition, which can be partly attributed to intractable environment changes in the backgrounds. This article presents a brain-inspired computing of attention value of surrounding environment changes (EC) with a processes-based cognition model by introducing a ratio value of EC-implications within considered periods. Theoretical models for computation of warning level of EC-implications to the universal video recognition efficiency (quantified as time cost of implication-ratio variations from to +1 , = 1, 2, . . .) are further established. Imbedding proposed models into the online algorithms is suggested as a future research priority towards precision security for critical applications and, furthermore, schemes for a practical implementation of such integration are also preliminarily discussed.

“…Because they can switch between two distinct flight modes, hybrid UAVs are quickly becoming increasingly popular. Several researchers were explored the enhancement of the hybrid VTOL UAV design [10][11][12][13][14][15][16][17][18][19][20][21][22]. A wingtip designs for a Quad+Tilt configuration with different control principles were proposed and gain of 3% improvement in cruise endurance for a 5 kg Quad+Tilt UAV [12].…”

Over the past few decades, unmanned aerial vehicles, commonly known as UAVs, have been widely used in a number of consumer and military applications, such as surveillance, tracking, monitoring, and aerial photography. Fixed-wing and rotary UAVs are the two primary categories in UAV. Interestingly, the hybridization of fixed-wing and rotary UAV gives better performance in terms of energy consumption and the needs of runaway. Designing new hybrid fixed wing-rotary UAV or hybrid vertical take-off and landing (VTOL) is challenging especially to identify the critical location in the UAV and material selection. Therefore, the objective of this research is to study the effect of empennage location and material selection on the structural strength of a hybrid VTOL UAV. The SolidWorks software was employed to design a 3D model of the UAV with different empennage locations, as well as perform a simulation of the structural strength of fibre glass, carbon fibre and kenaf for the hybrid VTOL UAV. The simulation analysis presents stress (Von Mises). The results show that the fibre glass (4.342 N/m2) at top empennage gives the best performance as compared to other parameters. In conclusion, this study is necessary to give a better picture of structural strength of composite materials and best design location in hybrid VTOL UAV for future research.

“…This is evident in urban environment where the usage of a runway is not possible, and UAVs usually have to fly at a relatively low speed and altitude. This "U-Space" [9] covers altitude up to 150 meters in the European Union and is an area for the development of a strong and dynamic drone services market [10]. In turn, multirotors [11,12] have the capability of vertical take-off and landing (VTOL), which increases their operational flexibility.…”

A challenging issue associated with fixed wing Unmanned Aerial Vehicles (UAVs) is that these vehicles are often not appropriate for operating effectively in limited airspace. This problem emerges especially in urban environment where the usage of a runway is not possible, and UAVs usually have to fly at a relatively low speed and altitude. The development of a vertical take-off and landing (VTOL) fixed-wing plane is a promising trend which hopefully will solve this issue. This project aims to address difficulties relating to reconnaissance and surveillance for military and civilian applications. The design concept simplifies tilt-rotor systems by using only the control fins to shift from horizontal to vertical flight and vice-versa, allowing the motor/rotor elements to be fixed. All the basic maneuvering of the aircraft is handled by the control surfaces of the airframe. The system consists of one wing with two motors and two elevons creating a tractor configuration airframe. The active flow over the surfaces assists in VTOL and allows the aircraft to seamlessly carry out vertical flight, such as hovering, and offer maneuverability at slow speeds during horizontal flight.
