MAPPING UNDERSTORY TREES USING AIRBORNE DISCRETE-RETURN LIDAR DATA [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
Understory trees in multi-layer stands are often ignored in forest inventories. Information about them would benefit silviculture, wood procurement and biodiversity management. Cost-efficient inventory methods for the assessment of the presence, density,

Virtual Network Mapping Algorithm Based on Adjacent Node and Topology Awareness [PDF]

open access: yesJisuanji gongcheng, 2018
The existing Virtual Network(VN) mapping algorithms have poor correlation between node mapping and link mapping,and the longer link mapping path leads to lower request acceptance rate and lower revenue overhead.To solve this problem,a VN mapping ...

Using intervention mapping to develop evidence-based toolkits that support workers on long-term sick leave and their managers

open access: yesBMC Health Services Research, 2023
Background Managing long-term sickness absence is challenging in countries where employers and managers have the main responsibility to provide return to work support, particularly for workers with poor mental health.

Implicit yield function formulation for granular and rock-like materials [PDF]

open access: yes, 2014
The constitutive modelling of granular, porous and quasi-brittle materials is based on yield (or damage) functions, which may exhibit features (for instance, lack of convexity, or branches where the values go to infinity, or false elastic domains ...

Elastoplastic analysis by complete implicit stress-update algorithm based on the extended subloading surface model

open access: yesNihon Kikai Gakkai ronbunshu, 2016
Elastoplastic analysis of solid structures under cyclic loadings is increasingly required in recent years. To this end, it is necessary to adopt elastoplastic model capable of describing cyclic loading behavior and to employ stress integration algorithm ...

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.
