The Impact

The use of unmanned aerial vehicles (UAVs) in various spheres of human activity is a promising direction for countries with very different types of economies. This statement refers to resource-rich economies as well. The peculiarities of such countries are associated with the dependence on resource prices since their economies present low diversification. Therefore, the employment of new technologies is one of the ways of increasing the sustainability of such economy development. In this context, the use of UAVs is a prospect direction, since they are relatively cheap, reliable, and their use does not require a high-tech background. The most common use of UAVs is associated with various types of monitoring tasks. In addition, UAVs can be used for organizing communication, search, cargo delivery, field processing, etc. Using additional elements of artificial intelligence (AI) together with UAVs helps to solve the problems in automatic or semi-automatic mode. Such UAV is named intelligent unmanned aerial vehicle technology (IUAVT), and its employment allows increasing the UAV-based technology efficiency. However, in order to adapt IUAVT in the sectors of economy, it is necessary to overcome a range of limitations. The research is devoted to the analysis of opportunities and obstacles to the adaptation of IUAVT in the economy. The possible economic effect is estimated for Kazakhstan as one of the resource-rich countries. The review consists of three main parts. The first part describes the IUAVT application areas and the tasks it can solve. The following areas of application are considered: precision agriculture, the hazardous geophysical processes monitoring, environmental pollution monitoring, exploration of minerals, wild animals monitoring, technical and engineering structures monitoring, and traffic monitoring. The economic potential is estimated by the areas of application of IUAVT in Kazakhstan. The second part contains the review of the technical, legal, and software-algorithmic limitations of IUAVT and modern approaches aimed at overcoming these limitations. The third part—discussion—comprises the consideration of the impact of these limitations and unsolved tasks of the IUAVT employment in the areas of activity under consideration, and assessment of the overall economic effect.

Error Method

This paper presents an enhanced particle swarm optimization (PSO) for the path planning of unmanned aerial vehicles (UAVs). An evolutionary algorithm such as PSO is costly because every application requires different parameter settings to maximize the performance of the analyzed parameters. People generally use the trial-and-error method or refer to the recommended setting from general problems. The former is time consuming, while the latter is usually not the optimum setting for various specific applications. Hence, this study focuses on analyzing the impact of input parameters on the PSO performance in UAV path planning using various complex terrain maps with adequate repetitions to solve the tuning issue. Results show that inertial weight parameter is insignificant, and a 1.4 acceleration coefficient is optimum for UAV path planning. In addition, the population size between 40 and 60 seems to be the optimum setting based on the case studies.

Global Hawk

In October 2018, the Korean Army established a Dronebot unit. The future battleground is expected to be led by drones and robots. However, in order to utilize new weapons systems such as drones and unmanned aerial vehicles (UAVs) in the Korean army, it is necessary to go through complicated and long-term defense acquisition procedures, which make it difficult to adopt and reflect the latest technologies immediately. The purpose of this study is to derive some implications for the efficient development and acquisition of UAVs in Korea through in-depth case analysis on the evolutionary development and acquisition of U.S. military UAVs. Accordingly, this study focused on the tactical/strategic U.S. fixed-wing UAVs which have been developed and mass-produced since 1990s, weighing more than 150kg. They include Shadow-200 as brigade/division-level UAV, Predator and Reaper as midium altitude UAVs, and Global Hawk as high altitude UAV. These must not only satisfy the required operational capability (ROC), but also receive strict airworthiness certification. Among them, Predator and Global Hawk were carried out as New Conceptual Technology Development Demonstration (ACTD), and prototypes under development were put into the Middle East battle. Although there were several accidents, flexible development processes such as system development or initial mass production were applied after ACTD. The initial target performance was set to be low and operability verification was prioritized, and the performance was improved through the evolutionary development of initial low rate mass production, subsequent mass production, and subsequent performance improvement. Despite the initial mass production phase, all required performance was not confirmed, and the required performance was presented in a range of flexibility. On the other hand, there have been large-scale changes such as engine replacement, aircraft change and communication systems upgrade to improve performance. Mission equipment was developed separately and applied to mass production when operability was confirmed. In the process of the development and acquisition of these UAVs, unforeseen accidents, huge losses and increased costs happened, but the U.S. government continued to pursue an evolutionary development policy for military drones. Therefore, in developing and acquiring new high-tech military unmanned aerial vehicles, it is necessary for Korea to develop and acquire them based on operability in the initial development stage, and to enhance its combat capabilities by improving its performance in the stages of initial mass production, follow-up mass production and performance improvement.

The Impact

Unmanned aerial vehicles, commonly called drones, are being increasingly used in ecological research, in particular to approach sensitive wildlife in inaccessible areas. Impact studies leading to recommendations for best practices are urgently needed. We tested the impact of drone colour, speed and flight angle on the behavioural responses of mallards Anas platyrhynchos in a semi-captive situation, and of wild flamingos ( Phoenicopterus roseus ) and common greenshanks ( Tringa nebularia ) in a wetland area. We performed 204 approach flights with a quadricopter drone, and during 80% of those we could approach unaffected birds to within 4 m. Approach speed, drone colour and repeated flights had no measurable impact on bird behaviour, yet they reacted more to drones approaching vertically. We recommend launching drones farther than 100 m from the birds and adjusting approach distance according to species. Our study is a first step towards a sound use of drones for wildlife research. Further studies should assess the impacts of different drones on other taxa, and monitor physiological indicators of stress in animals exposed to drones according to group sizes and reproductive status.

Better Than

This paper investigates how counterterrorism targeting terrorist leaders affects terrorist attacks. This effect is theoretically ambiguous and depends on whether terrorist groups are modeled as unitary actors or not. The paper exploits a natural experiment provided by strikes by Unmanned Aerial Vehicles (drones) “hitting” and “missing” terrorist leaders in Pakistan. Results suggest that terrorist groups increase the number of attacks they commit after a drone “hit” on their leader compared with after a “miss.” This increase is statistically significant for 3 out of 6 months after a hit, when it ranges between 47.7% and 70.3%. Additional analysis of heterogenous effects across groups and leaders, and the impact of drone hits on the type of attack, terrorist group infighting, and splintering, suggest that principal-agent problems—(new) terrorist leaders struggling to control and discipline their operatives—account for these results better than alternative theoretical explanations.
