On the Effectiveness of UAS for Anti-Poaching in the African Arid Savanna

AbstractThis paper describes a field study that examined the effectiveness of unmanned aerial vehicles (UAV) in anti-poaching enforcement in parks and game reserves. In the field study, a UAV attempted to spot mock poachers while the mock poachers tried to spot the UAV. The field study was conducted at N/a’an ku sê, an operational game reserve in the central region of Namibia. In total, 118 trials were completed, providing 236 UAV-poacher interdiction scenarios. Of these, 198 were during the day, 152 with a quadcopter and 46 with a fixed-wing. Live spotting success during the day varied due to the hiding behavior of the mock poachers, with the highest and lowest success rates of spotting being 86% for poachers in the open and 25% for poachers hiding under canopy cover. The UAVs were demonstrated to be a potentially effective tool for anti-poaching patrol and interdiction, in part, because of their ability to spot poachers. The pursuit of integrating the UAV into current anti-poaching patrol and interdiction efforts in arid savanna landscapes is strongly recommended.

A field study explored driver behavior at complex interchanges throughout the United States in order to better understand geometric, signing, and marking characteristics that influence driving behavior and lane selection. Two types of data were collected at 13 interchanges spanning four states: videos from fixed-location cameras, and videos from unmanned aerial vehicles. Findings from the study highlight common behavior as drivers negotiate complex interchanges. For each interchange studied, video was reduced to track vehicle paths throughout the study site. Although data were captured on both through and exiting traffic, the focus of this review was on the exiting vehicles. No major safety issues were observed through the study. One common finding across all sites was that exiting traffic was found to most commonly use the EXIT ONLY lane rather than the option lane. In addition, few common behaviors identified through the video show last-minute lane changes; drivers typically entered their target lane well upstream of the interchange.

Nowadays, the creation of remotely-piloted aerial vehicles for various purposes is regarded as one of the most relevant and promising trends of aircraft development. FAU "25 State Research Institute of Chemmotology of the Ministry of Defense of the Russian Federation" have studied the operation features of aircraft piston engines and developed technical requirements for motor oil for piston four-stroke UAV engines, as well as a new engine oil M-5z/20 AERO in cooperation with NPP KVALITET, LLC. Based on the complex of qualification tests, the stated operational properties of the experimental-industrial batch of M-5z/20 AERO oil are generally confirmed.
