Parallel projection—An improved return mapping algorithm for finite element modeling of shape memory alloys [PDF]
Computer Methods in Applied Mechanics and Engineering, 2021 We present a novel finite element analysis of inelastic structures containing Shape Memory Alloys (SMAs). Phenomenological constitutive models for SMAs lead to material nonlinearities, that require substantial computational effort to resolve.

RETURN-MAP CRYPTANALYSIS REVISITED [PDF]
International Journal of Bifurcation and Chaos, 2006 As a powerful cryptanalysis tool, the method of return-map attacks can be used to extract secret messages masked by chaos in secure communication schemes. Recently, a simple defensive mechanism was presented to enhance the security of chaotic parameter modulation schemes against return-map attacks. Two techniques are combined in the proposed defensive

TOPOGRAPHIC MAPPING WITH MANIPULATOR ARM CAMERA IN LUNAR SAMPLE RETURN MISSION [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 The topographic mapping of sampling areas, providing basic sampling environment information, is crucial in sample return mission. The fixed monitoring cameras were designed for mapping of sampling areas in fixed effective resolution.

Identifying robust bias adjustment methods for European extreme precipitation in a multi-model pseudo-reality setting [PDF]
Hydrology and Earth System Sciences, 2021 Severe precipitation events occur rarely and are often localised in space and of short duration, but they are important for societal managing of infrastructure.

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

Return mapping algorithm for elasto-plastic deformation of thin walled pipes
International Journal of Pressure Vessels and Piping, 2020 Return mapping algorithms are popular procedures for evaluating elasto-plastic material behaviour. This paper presents a dedicated return mapping algorithm for thin walled pipes and vessels with Von Mises plasticity and isotropic hardening, for which it ...
