Assessing Capability Complexity Using Enterprise Architecture Framework

Systems Engineering, EarlyView.
ABSTRACT This study proposes a structured and quantitative methodology to evaluate the holistic complexity of system‐of‐systems (SoSs), employing the Zachman Architecture Framework (ZAF) as its foundational analytical tool. A five‐phase analytical procedure is developed and empirically validated, encompassing: (1) refinement of complexity measures, (2)

Research on a Drone‐Based Vacant Parking Detection System

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
It can be difficult to know which spaces are available in parking lots and bicycle parking areas, so knowing the availability status is necessary for efficient parking. Therefore, in this study, we developed the drone that can display the availability status. Availability is determined by whether it can read a QR code attached to the ground. To conduct

Light tuned to the avian eye elicits early detection and escape from an approaching aircraft

Royal Society Open Science
Collisions between birds and aircraft are a global problem. We identified different behavioural parameters affecting the probability of escape from a potential collision with an approaching aircraft, which is a function of the probability that the animal

Monitoring GPS‐collared moose by ground versus drone approaches: efficiency and disturbance effects

Wildlife Biology, EarlyView.
Efficient wildlife management requires precise monitoring methods, for example to estimate population density, reproductive success, and survival. Here, we compared the efficiency of drone (equipped with a RGB camera) and ground approaches to detect and observe GPS‐collared female moose Alces alces and their calves. We also quantified how drone (n = 42)

Spraying drones: efficacy of integrating an avian repellent with drone hazing to elicit blackbird flock dispersal and abandonment of sunflower fields

Wildlife Biology, EarlyView.
Multiple management strategies exist to combat bird damage to agriculture. We explored combining two tools, drones as frightening devices and an avian repellent, to assess effectiveness of an integrated method to deter large flocks on complex landscapes. We evaluated the ability of a spraying drone (DJI Agras MG‐1P) deploying Avian Control (i.e. active
