Evaluation of prestress losses in concrete beams using destructive and non‐destructive methods
Structural Concrete, EarlyView.Abstract Over the past few decades, prestressing techniques have become essential in the construction of key structures, infrastructure, and bridges. The serviceability and safety of prestressed concrete (PC) elements are closely tied to the effectiveness of the prestressing process.

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

Ungulate substrate use in fauna passages
Wildlife Biology, EarlyView.Fauna passages are increasingly constructed at major roads and railways to mitigate the negative effects of infrastructure and traffic on wildlife. The function of such passages depends on design, including the construction materials, soil, and vegetation.

Wildlife Biology, EarlyView.Urban green spaces experience a mix of natural and anthropogenic noises, which could disrupt the vocal communication of several species. This study investigated how such complex soundscapes affect the occurrence of Anaxipha pallidula, which communicates through calls, focusing on both sound level and quality.
