A 3D Interferometer-Type Lightning Mapping Array for Observation of Winter Lightning in Japan

open access: yesRemote Sensing, 2023
We have developed and deployed a 3D Interferometer-type Lightning Mapping Array (InLMA) for observing winter lightning in Japan. InLMA consists of three broadband interferometers installed at three stations with a distance from 3 to 5 km.

UAS FOR GEO-INFORMATION: CURRENT STATUS AND PERSPECTIVES [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
Recent and ongoing developments of state-of-the-art sensor technologies have resulted in smaller and lighter photogrammetric cameras with IMU, lidar scanners and other sensors that can now be integrated with and mounted on the larger Light UAS.

On decomposing mixed-mode oscillations and their return maps [PDF]

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 2011
Alternating patterns of small and large amplitude oscillations occur in a wide variety of physical, chemical, biological, and engineering systems. These mixed-mode oscillations (MMOs) are often found in systems with multiple time scales. Previous differential equation modeling and analysis of MMOs have mainly focused on local mechanisms to explain the ...

Development of a workplace intervention for sick-listed employees with stress-related mental disorders: Intervention Mapping as a useful tool

open access: yesBMC Health Services Research, 2007
Background To date, mental health problems and mental workload have been increasingly related to long-term sick leave and disability. However, there is, as yet, no structured protocol available for the identification and application of an intervention ...

A Return Mapping Algorithm for Nonlinear Yield Criteria with the Equivalent Mohr–Coulomb Strength Parameters

open access: yesAdvances in Civil Engineering, 2020
This paper proposes a modified return mapping algorithm for a series of nonlinear yield criteria. The algorithm is established in the principal stress space and ignores the effect of the intermediate principal stress.

Mapping snow depth return levels: smooth spatial modeling versus station interpolation [PDF]

open access: yesHydrology and Earth System Sciences, 2010
For adequate risk management in mountainous countries, hazard maps for extreme snow events are needed. This requires the computation of spatial estimates of return levels. In this article we use recent developments in extreme value theory and compare two

Assessing the capacity of large-scale hydrologic-hydrodynamic models for mapping flood hazard in southern Brazil

open access: yesRBRH, 2022
Mapping flood risk areas is important for disaster management at the local, regional, and national scales. The aim of this study was to evaluate the ability of large-scale models to obtain flood hazard maps.

Analysis of the springback phenomenon using finite element method

open access: yesVietnam Journal of Mechanics
The springback phenomenon is a significant concern in manufacturing processes, particularly in metal component forming, as it directly affects dimensional control and the shape of formed parts.
